ASHGABAT — Authorities in Turkmenistan have yet to admit there are any cases of the coronavirus in the country. Now, officials are making sure the word doesn’t appear in print or casual conversations either.
The word “coronavirus” also has disappeared from newly published state brochures on disease prevention in the tightly controlled Central Asian nation.

In place of old brochures instructing citizens about ways to prevent the spread of the virus, new publications replace the word “coronavirus” with words like “illness” and “acute respiratory diseases.”
“The Turkmen authorities have lived up to their reputation by adopting this extreme method for eradicating all information about the coronavirus,” said Jeanne Cavelier, head of the Eastern Europe and Central Asia desk of the media rights group Reporters Without Borders (RSF).
The lack of any report confirming even one coronavirus infection in Turkmenistan has raised suspicions and criticism about the country’s official data on the pandemic.
Countries that border Turkmenistan — including Kazakhstan, Uzbekistan, and Afghanistan — have registered dozens of infections.
To the south, nearby Iran had reported more than 44,700 infections by March 31, including nearly 3,000 deaths.
Turkmenistan’s government sealed off Ashgabat on March 20 without any public announcement by authorities or state media about the reasons for the closure.
Traffic between the country’s provinces has been restricted as well, with checkpoints set up on highways.
Concern over the outbreak among locals, along with the restrictions, has pushed food prices to record highs.
“This denial of information not only endangers the Turkmen citizens most at risk but also reinforces the authoritarianism imposed by President Gurbanguly Berdymukhammedov,” Cavelier said on March 31. “We urge the international community to react and to take him to task for his systematic human rights violations.”
Members of the House Veterans Affairs Committee called on the Senate on Dec. 20, 2018, to vote on the Blue Water Navy Vietnam Veterans bill before the legislative body heads home for the holidays.
During a press conference, committee chairman Rep. Phil Roe, R-Tenn., and Rep. Mark Takano, D-Calif., the ranking member and committee’s next chairman, pressed for a floor vote after an effort failed Dec. 19, 2018, in the Senate.
“There’s a joke that sometimes the enemy is not the other party, it is the Senate. They are not really the enemy, but they are being very difficult,” Takano said.
On Dec. 19, 2018, Sen. Mike Lee, R-Utah, blocked a move to pass the bill, the Blue Water Navy, Vietnam Veterans Act of 2018, by unanimous consent. Lee wants to wait for a Department of Veterans Affairs report, due out in 2017, on whether health issues diagnosed in Blue Water veterans actually are related to Agent Orange exposure.

“The brave men and women who have sacrificed so much for our country should undoubtedly get the medical care they need in connection with their service. But … it’s also our duty to ensure that this is done in a prudent and proper way with all the relevant information available to us,” Lee said, speaking on the Senate floor on Dec. 19, 2018.
Lee’s objection, as well as concerns by Sen. Mike Enzi, R-Wyoming, over the bill’s estimated .2 billion cost over 10 years, was enough to block the bill in the Senate, where lawmakers hoped to pass it by unanimous consent, which would not require a floor vote of all senators.
But House members, who passed the bill 382-0 in June 2018, proposed that the Senate hold a floor vote.
Roe admitted that the existing studies that link health conditions in Navy veterans to Agent Orange aren’t definitive, but he added that it’s time to “move past that.”
“We’re this close to solving a decades-old problem for 90,000 of our colleagues. If we wait long enough, it won’t matter because they’ll all be gone,” Roe said.
The bill would provide compensation for veterans who served on Navy ships off Vietnam and have diseases that have been linked to Agent Orange in ground-based Vietnam veterans. These “Blue Water” veterans have pushed for years to get health care and compensation for their service-connected illnesses and disabilities.
In 2002, the VA ruled that veterans must have served on the ground in Vietnam to receive Agent Orange-related benefits; personnel who served on certain vessels that patrolled inland waterways also are eligible.

Veterans and their advocates say the exclusion of personnel who served on ships offshore is unfair, as studies indicate that troops may have been exposed when they showered or drank water on their vessels that was distilled from contaminated sea water.
Under the House proposal, the cost of the bill would be offset by raising interest rates for VA home loans for active-duty service members. “I feel very comfortable that this bill is fully funded,” Roe said.
VA officials, however, have objected to the measure, saying it puts a burden on young active-duty troops as well as disabled veterans.
Sen. Richard Blumenthal, D-Connecticut, pledged Dec. 19, 2018, that the Senate would take up the measure next year. “[These veterans] have been denied year after year. … Asking them to wait denies them justice. … These veterans very simply are passing away; they will be denied of these benefits owed them.”
The bill also would broaden coverage for veterans who served in the Korean demilitarized zone, where defoliants were tested, and also expand benefits to children with spina bifida caused a parent’s exposure in Thailand.

The Magnum P.I. and Blue Bloods star may be best known for Hawaiian shirts and the Gatling gun of mustaches, but did you know he also served in the Guard?
After he was drafted during the Vietnam War, Selleck joined the 160th infantry regiment of the California National Guard. “I am a veteran. I’m proud of it,” he said. “I was a sergeant in the U.S. Army infantry, National Guard, Vietnam era. We’re all brothers and sisters in that sense.”
Selleck served from 1967 to 1973, including six months of active duty. Before his military career, however, Selleck had already begun to pursue the entertainment industry, including commercial work and modeling, which makes it no surprise that he would later appear on California National Guard recruiting posters.
Former National Guard member, Tom Selleck, shares Guard facts in this 1989 commercial
In the video, Selleck uses a mixture of voiceover and direct-to-camera dialogue interspersed with facts about the National Guard throughout modern conflicts and operations: “Some people think the National Guard is just an excuse for a bunch of guys to get together and have a good time. That they’re not as trained or committed as other branches of the military. That they’re weekend warriors — not real soldiers. And people wonder what business they have being in a foreign country. Well I can’t clear up all the misconceptions people have about the National Guard so let me leave you with one important fact: if you bring together all the ready forces of the Army, Air Force, Navy, Marines and Reserves, you still have only half the picture. The other half? The National Guard, skilled, capable, intelligent people. People like you and me. American’s at their best.”
The video is certainly different from what contemporary audiences are accustomed to. While modern recruiting videos show off assets and firepower, this one feels a little more solemn and defensive. This may be a reflection of the nation’s shift in National Guard duty rights during the 80s.
In 1986, Congress passed a Federal law known as the Montgomery Amendment, which removed state governors’ power to withhold consent for orders summoning National Guard units to active duty without a national emergency. The law was originally created in response to the decision made by several governors to withhold their consent to send units for training in Honduras. In 1989, a Federal appeals court upheld the law when it was challenged by the Massachusetts and Minnesota governors.
According to the 1989 Profile of the Army, additional missions were transferred to the National Guard and Army Reserve as the Army increased its focus as an integrated and cohesive “TOTAL FORCE” ready to respond to Soviet attacks on NATO or the Persian Gulf and defend U.S. interests abroad.
Selleck’s patriotism extended beyond his service to recruitment just in time to help boost numbers before the Persian Gulf War the following year.
Ukraine has become a defining feature of the 2020 presidential election season. Here are some facts to help you better understand Ukraine’s role on the global stage:
Traditional Ukrainian embroidered blouses.
Medieval Ukraine, known as “Kievan Rus,” was the birthplace of Slavic culture. Ukraine was formerly part of the Soviet Union and became an independent country in 1991. The country has long been known as the “breadbasket of Europe” due to its fertile soil. Although its economy has improved steadily since 2000, Ukraine continues to suffer from poverty and corruption. Ukraine is a close ally of the United States, and polls have shown a generally positive attitude toward the U.S. by Ukrainians.

Ukraine has been at war since 2014
Ukraine was rocked with instability in 2014 due to a political protest movement called “Euromaidan.” Russia seized this opportunity to invade Ukraine’s Crimean peninsula and claim it as Russian territory while also stirring up pro-Russian separatists in eastern Ukraine. Crimea was conquered without bloodshed, and a large proportion of Crimea’s residents actually support the annexation. The insurrection in eastern Ukraine, however, quickly became violent.
Today the Ukrainian military continues to fight heavily armed, Russian-backed separatists and Russian military forces (although Russia publicly denies the latter) in eastern Ukraine. The conflict, which has claimed at least 13,000 lives and displaced over 1.4 million people, has since become a stalemate.

Euromaidan was a really big deal
In 2014, growing discontent against president Viktor Yanukovych erupted in a massive protest movement. The activists, who hoped for a Ukraine more oriented toward Western Europe, accused Yanukovych of being a puppet of Vladimir Putin trying to pull Ukraine closer into Russia’s orbit. The Euromaidan movement led to street battles between police and protesters and over 100 deaths.
Euromaidan eventually succeeded, however. Yanukovych abandoned the presidency and fled to Russia, where he remains to this day. (In 2019 a Ukrainian court convicted him, in absentia, of treason.) Euromaidan was historic because it reflected the will of many Ukrainians to choose a trajectory free of Russian domination, but it also aggravated simmering tensions within Ukraine’s population and triggered Russia’s armed interventions in Crimea and the eastern regions.

The Ukrainian population is deeply divided
Many Ukrainians, especially in western Ukraine, are staunch Ukrainian patriots. They take great pride in Ukrainian culture, history, and language and generally hold negative attitudes toward Russia.
More eastern regions of the country, however, have larger percentages of Ukrainians who speak Russian as a first language and consider themselves more Russian than Ukrainian. This is the root of the current war in eastern Ukraine, and the reason many Ukrainians in Crimea welcomed Russian annexation in 2014.
Choose your words carefully when referring to Ukraine
There are some semantics involved when speaking of Ukraine which cannot be divorced from the country’s complicated history and politics. Even the name “Ukraine” means “borderland” in Russian. The Ukrainian capital city has historically been transliterated as “Kiev,” the traditional Russian spelling, although the Ukrainian-language “Kyiv” is increasingly preferred.
Likewise, many English speakers incorrectly refer to the country as “the Ukraine,” a dated reference to the Soviet era when Ukraine was a Soviet republic (similar to saying “the Midwest” in relation to the United States). Both the Ukrainian government and many Ukrainians strongly discourage the term “the Ukraine.”
Even language itself is contentious: the majority of Ukrainians can speak both Ukrainian and Russian, but the use of either language can be seen as a political and social statement by the speaker.

Ukraine’s current president is literally a comedian
Current president Volodymyr Zelensky, whose phone call with President Donald Trump in July 2019 has triggered controversy within the United States, was a comedian before being elected in a landslide in 2019. He is most famous for playing the lead role in “Servant of the People,” a hugely popular sitcom about a schoolteacher who is unexpectedly elected president of Ukraine.
The 41-year-old Zelensky ran for office as a reformer whose priorities include fighting corruption and negotiating an honorable end to the war. Zelensky also wants to maintain U.S. support, particularly American shipments of “lethal” aid such as anti-tank missiles, which Ukrainian troops need to counter the Russian-equipped rebels.
Although a longtime Ukrainian patriot, Zelensky’s first language is Russian, and he has been criticized for not being entirely fluent in Ukrainian.
Although the U.S. mission in Iraq is often referred to as one of advising and assisting, only about 25 percent of the 101st Airborne Division‘s 2nd Brigade Combat Team was doing that during its deployment to Iraq, which concluded in January, the brigade’s commander said at the Pentagon May 3 during a media roundtable discussion of the deployment.
Army Col. Brett Sylvia, the brigade’s commander, told reporters that the other 75 percent of his Task Force Strike soldiers were engaged in route clearance, expedited communications, air and ground coordination, and logistics, which enabled Iraq to build up its forces up and get to their tactical assembly area for the push into eastern Mosul, which began Oct. 17 as part of the effort to liberate Iraq’s second-largest city from the control of the Islamic State of Iraq and Syria.
When Task Force Strike arrived in Iraq in April 2016, the Air Force was delivering all the precision strike capability to the Iraqis fighting ISIS, Sylvia said. Over the course of the deployment, Task Force Strike soldiers augmented much of that strike capability with their own artillery and unmanned aerial vehicle assets. About 6,000 artillery rounds were fired, he added.
Sylvia said he was pleased with the authorities the U.S. commanders on the ground were given to call for fire to enable the Iraqi ground forces to move forward. In March 2016, the month before the task force arrived in Iraq, the authority was granted not only to the general in charge of the operation, but also for colonels, lieutenant colonels, and in at least one case, a captain near the front of the fighting, he explained.
Although the Iraqis did the fighting, some limited situations arose when U.S. soldiers accompanied them to provide “niche capability,” Sylvia said. For example, he said, soldiers accompanied an Iraqi battalion on a bridge-building mission on the Tigris River, where the enemy had blown up the bridge. The soldiers advised them on establishing area security as the U.S.-made bridge was erected, he told reporters.
Militia fighters not attached to the Iraqi army who also were fighting ISIS were pretty much segregated from Iraqi forces, Sylvia said. U.S. forces were aware of their location and movements, he added, but did not interact with them in any way.
In one day alone, 12 appeared, he noted — mostly quadcopters operated by Wi-Fi with about 45 minutes of flight time.
At first, he said, the enemy used them for intelligence, surveillance, and reconnaissance and to obtain video for use as propaganda on social media sites.
Over time, Sylvia said, the enemy managed to mount 40 mm grenades on the UAVs and drop them. It was primitive, such as when World War I pilots tossed bombs out of their airplanes by hand, he said. It’s not precision bombing, but it’s more effective than their indiscriminate bombing, the colonel told reporters.
Over time, U.S. forces employed countermeasures that stopped or slowed their flight, enabling Iraqi ground forces to shoot them out of the sky, he said, noting that the new threat from the air led to dusting off old manuals on how to respond to threats from the air with countermeasures such as camouflage.
Best Day in Iraq
Sylvia said he clearly recalls his best day in Iraq. It was Christmas Day, and Iraqi forces, who are Muslim, invited him and his soldiers to a Christian church just outside Mosul to attend services. ISIS had gutted the church, but the Iraqis had rebuilt it with their own money.
“It was a powerful symbol, and was amazing,” he said of the visit to the church, adding that he hopes the relationship forged with the Iraqis will be enduring.

While Russia likes to point to the “successes” of its state re-armament program, the fact is that many of the weapons have fallen well short of their touted potential. The T-14 is underfunded and probably overhyped. The Su-57 can’t be stealthy and fast at the same time. The nuclear-powered cruise missile might be what killed Russian scientists last month.
The RSM-56 Bulava missile has some problems that we’ll get into in a minute, but on paper, it’s one of the most impressive weapons in the world today.
These nuclear-armed missiles are able to fly over 5,000 miles from the Borei-class submarine that launched them. That’s far enough for the sub to fire from the southern coast of Brazil and hit anywhere on the U.S. East Coast. And when it hits, it hits hard. Estimates of its punching power vary, but it’s thought to carry between 6 and 10 independently targeted warheads. And each warhead has a 100-150 kiloton yield.
While it’s hard to get good numbers for how far the different warheads can spread, each one can essentially take out a city, and those cities can likely be spread 100 miles or more apart. Oh, and each sub carries 12-16 missiles.
Add to all of that the warhead follows a lower arc, foiling many missile defenses, and can deploy decoy warheads. It’s a recipe for absolute destruction. Each submarine can take out, conservatively, 72 city-sized targets. Well, they can do so if each missile works properly.
Russia overhyped the Su-57, failed to field the T-14 in significant numbers, and then claimed its nuclear-powered cruise missile was ready to go about a year before that missile blew up in testing and killed top scientists. So, yeah, there’s always the possibility that the Bulava doesn’t work as advertised.
But since the missiles have had successful tests and can take out entire regions of America, it could legitimately be the last thing millions of Americans ever see if there’s a nuclear shooting match between the U.S. and Russia. But hey, at least the suspense won’t last long.
As tensions rise to historic heights on the Korean Peninsula, both the U.S. and China have begun taking unprecedented steps to prepare for the worst-case scenario.
Across North Korea’s border in China’s Jilin province, state-run media ran a full-page instructional package on how to survive a nuclear blast. The page doesn’t mention North Korea, but it doesn’t need to.
But China’s preparations don’t just indicate a defensive, wait-and-see approach. China’s air force engaged in exercises along “routes and areas it has never flown before” earlier this month, with surveillance aircraft over the Yellow and East seas near the Korean Peninsula, according to the South China Morning Post.
“The timing of this high-profile announcement by the PLA is also a warning to Washington and Seoul not to provoke Pyongyang any further,” Li Jie, a military expert based in Beijing, told the Post, using the abbreviation for the Chinese People’s Liberation Army.
In addition to flexing its military muscle against the U.S., China has been increasingly assertive in the South China Sea. It has also dispatched military spy planes to encircle Taiwan and provide up-to-date info, which the Macau-based military observer Antony Wong Dong told the Post was “very unusual.”
U.S. preparing to denuclearize North Korea, possibly by force
The U.S. appears resolutely determined to put the pressure on North Korea.
At a speech at the Atlantic Council last week, Secretary of State Rex Tillerson said the U.S. was preparing plans to seize loose nuclear weapons, should North Korea somehow collapse or become unstable.
President Donald Trump’s national security adviser, H.R. McMaster, also flatly rejected the clearest path to peace by saying the U.S. would never accept a nuclear-armed North Korea. He recommitted the U.S. to using force if necessary.
“We’re not committed to a peaceful resolution — we’re committed to a resolution,” McMaster told the BBC. “We have to be prepared, if necessary, to compel the denuclearization of North Korea without the cooperation of that regime.”
The Trump administration’s approach to North Korea explicitly calls for every means of pressure to bear down on the country. Threats of war, military deployments, increased drills, stealthier and more lethal weapons systems, sanctions, and even a possible shipping blockade could become a daily fact of life for Pyongyang under Trump.
But North Korea is not the only one to have noticed the U.S.’s new approach. China has closely watched the U.S. ratchet up tensions along its border, and its recent military movements reflect a country that is considering all-out war a possibility.

Proposed amendments to the fiscal 2021 National Defense Authorization Act would add three diseases to the Department of Veterans Affairs‘ list of illnesses presumed to be linked to Agent Orange — measures that, if approved, would provide health care and disability benefits to roughly 22,000 affected veterans.
The House and Senate amendments, proposed by Rep. Josh Harder, D-California, and Sen. Jon Tester, D-Montana, would add bladder cancer, hypothyroidism and Parkinsonism to the VA’s list of 14 conditions considered related to herbicide exposure during the Vietnam War.
In 2016, the National Academies of Sciences, Engineering and Medicine deemed the three named diseases to be associated with exposure to defoliants used during the war.
But the proposals do not include hypertension, a condition that the Academies also linked to Agent Orange in 2018. Hypertension, or high blood pressure, is common among the elderly and, if included, could add more than 2 million veterans to VA disability rolls in the next 10 years, at an estimated cost of $11.2 billion to $15.2 billion, according to department estimates.
Thirty veteran and military groups have backed the proposals and asked congressional leaders to do the same.
On Tuesday, the Veterans of Foreign Wars, Vietnam Veterans of America, Military Officers Association of America and 27 other groups wrote House and Senate leaders urging them to get behind the provisions.
“We call on you to lead and pass House Amendment 264 into law and end the waiting for many of our nation’s ill veterans so they can receive disability benefits,” stated letters sent to House Speaker Nancy Pelosi, House Minority Leader Kevin McCarthy, Senate Majority Leader Mitch McConnell and Senate Minority Leader Chuck Schumer.
“There is more work to be done to care for those who are ill from toxic exposures, including adopting hypertension as a presumptive disease … but with your leadership, tens of thousands of Vietnam War veterans will receive their benefits and justice,” they wrote.
A decision on whether to add the three conditions has been delayed since 2017, when then-VA Secretary David Shulkin expressed support for including them but never formally announced his decision.
According to internal VA documents, Shulkin had been on the verge of including the three conditions when the Office of Management and Budget and other White House officials objected, citing what they called “limited scientific evidence” and cost.
Meanwhile, thousands of veterans have waited.
“Vietnam vets have been waiting for this for decades, and it’s a national shame that it’s not fixed yet,” Harder told Military.com. “We have a real chance here to make this right after all this time, and we should seize the opportunity.”
VA Secretary Robert Wilkie told lawmakers late last year he wants the results of two studies — the Vietnam Era Health Retrospective Observational Study, or VE-HEROES, and the Vietnam Era Mortality Study — to be reviewed for publication before announcing a decision on whether to broaden the presumptives list.
But lawmakers and advocacy groups have balked at the delay.
“This is something we are still fighting after how many decades from the Vietnam War?” asked Corey Titus, director of veterans benefits and Guard/reserve affairs at MOAA. “We should be making sure there aren’t any service members with illnesses who aren’t getting the care and benefits they earned.”
In February, Rep. Mark Takano, D-California, chairman of the House Veterans Affairs Committee, penned a letter to President Donald Trump asking him to “take corrective action” and add all four diseases to the list, including hypertension.
“Your administration has the ability to add these conditions to the presumptive list and provide lifesaving benefits to more than 190,000 veterans. Without your action, tens of thousands of sick and aging veterans will continue to go without VA resources and health care in their time of need,” he wrote.
The letter was signed by 77 members, all Democrats.
While hypertension is not included in the proposed amendment, the coalition of veterans and military organizations pledged to continue working on adopting it as a “presumptive disease as linked by the National Academies.”
“This needs to be covered as well. This is not something that we will forget — hypertension,” Titus said.
The House and Senate Armed Services Committees have both passed their versions of the fiscal 2021 defense bill and forwarded them to their respective chambers for consideration. Currently, committees are weighing the rules for amending and deliberating the bills before they move ahead for debate.
Both Harder and Tester’s proposals must make it through that process before coming up for a vote.
A legislative source said Tester’s amendment has been identified for a vote.
“With a bipartisan team of lawmakers and the support of the entire veterans community, we have a strong chance to finally get this done,” Harder said.
They don’t even put Charms in MREs anymore. Because if everyone is just going to chuck the candy out the Humvee window, that’s just a gross waste of high-fructose corn syrup.
Those who aren’t new to the service and have ever deployed with Marines probably saw the same scene at some point. Hungry Marines pour into their MREs and take out their favorite parts and toss the rest into the MRE box (a process known as ratf*cking). Let’s face it, some MRE parts are definitely better than others.
No matter what an individual’s tastes were, one item was always discarded: the Charms candy. The reason for that was a mixture of superstition and because the younger guys knew someone would slap the candy out of their hands or out of their mouths for the cardinal sin of even opening the wrapper.
The simplest answer is that Marines grow up in the Corps learning that Charms are just plain bad luck. Whether it was learned from saltier Marines or experienced firsthand, those things might as well be pure evil.
Eating Charms is like begging for the world’s largest thunderstorm to rain down on you and your platoon – even in the desert. Or they might set off a roadside bomb. Some think you’ll get mortared just for opening an MRE with Charms in it – unless you bury it.

The luck varied as much as the flavors did. As Sgt. Kenneth Wilson told Agence France-Presse just before the U.S.-led invasion of Iraq, a lemon-flavored Charm could cause a vehicle breakdown. The green ones were the ones that brought the rain. Raspberry meant certain death.
A growing body of research indicates that there are likely billion of Earth-like planets that we haven’t yet discovered.
That’s good news for astronomers seeking alien life. Since Earth is our only example of a life-bearing world, scientists try to pinpoint planets like ours when they search for life elsewhere.
That’s what NASA’s Kepler space telescope set out to do. Kepler scanned the skies from 2009 to 2018, and it found over 4,000 planets outside our solar system. A dozen or so of these planets seem like prime real estate for life.
Kepler’s data has produced a growing body of research that indicates there are likely billions more Earth-like planets that we haven’t discovered.
Here’s why scientists are starting to think planets like Earth might be common.
Nine years’ worth of observations by the Hubble Space Telescope revealed about 10,000 galaxies in one of the deepest, darkest patches of night sky in the universe.
Most of what we know about exoplanets comes from the planet-hunting Kepler space telescope.
Kepler, which first launched in 2009, retired last year after it ran out of fuel. NASA passed the planet-hunting torch to the Transiting Exoplanet Survey Satellite (TESS), which launched in April 2018.
From the International Space Station, astronaut Scott Kelly took this photo of Earth and the Milky Way. He posted it to Twitter on Aug. 9, 2015.
So Ford’s team built a simulation of a universe like ours and “observed” its stars as Kepler would have.
The simulation gave the scientists a sense of how many exoplanets Kepler would have detected in each hypothetical universe, and which kinds. They then compared that data to what the real Kepler telescope detected in our universe, to estimate the abundance of Earth-sized planets in the habitable zones of sun-like stars.
This artist’s impression shows an imagined view from nearby one of the three planets orbiting an ultracool dwarf star just 40 light-years from Earth.
The result: up to 10 billion rocky, Earth-sized planets in the habitable zones of sun-like stars.
“There are significant uncertainties in what range of stars you label ‘sun-like,’ what range of orbital distances you consider to be ‘in the habitable zone,’ what range of planet sizes you consider to be ‘Earth-like,'” Eric Ford, a professor of astrophysics and co-author of the study, told Business Insider in August 2019. “Given those uncertainties, both 5 and 10 billion are reasonable estimates.”

Many of those planets could be Earth-like in other ways, too. Last week, a study found that 87% of Earth-like planets in two-star systems should have a stable axis tilt like Earth’s.
“Multiple-star systems are common, and about 50% of stars have binary companion stars,” Gongjie Li, a co-author on the study, said in a press release. “So, this study can be applied to a large number of solar systems.”
The surface of Mars.
That stable tilt is crucial for life on Earth. The tilt of Mars’s axis changes wildly over tens of thousands of years, creating drastic shifts in global climate that could prevent life from taking hold.
Some scientists think Mars’s changing axial tilt contributed to the disappearance of its atmosphere.
A star like our sun dies by casting off its outer layers of gas, leaving only the star’s hot core behind.
In an autopsy of six dead stars, researchers found that the shredded remains of rocky planets contained oxygen and other elements found in rocks on Earth and Mars.
The researchers used telescope data to calculate how much the iron in these rocks had oxidized — the process where iron chemically bonds with oxygen and rusts.
“The fact that we have oceans and all the ingredients necessary for life can be traced back to the planet being oxidized as it is. The rocks control the chemistry,” Edward Young, a co-author on the study, said in a press release. “We have just raised the probability that many rocky planets are like the Earth, and there’s a very large number of rocky planets in the universe.”
An artist’s representation of Venus with land and water.
Earths might even be common in our own solar system. Venus may have had oceans and a climate like Earth’s for billions of years.
In September 2019, researchers presented the results of five different simulations of the climate history of Venus. In all five scenarios, the planet maintained temperatures between 20 and 50 degrees Celsius for up to 3 billion years.
NASA’s Galileo spacecraft took this colorized picture of Venus on Feb. 14, 1990, from a distance of almost 1.7 million miles.
The researchers think that a mysterious catastrophe about 700 millions years ago transformed Venus into the uninhabitable hothouse it is today.
“Something happened on Venus where a huge amount of gas was released into the atmosphere and couldn’t be re-absorbed by the rocks,” Michael Way, a NASA scientist and study co-author, said in a press release.
It could have been magma bubbling up from below Venus’s surface, releasing tons of carbon dioxide into the atmosphere. That would have trapped enough heat to reach the broiling surface temperatures that average 462 degrees Fahrenheit today.
“It is possible that the near-global resurfacing event is responsible for its transformation from an Earth-like climate to the hellish hothouse we see today,” Way added.
On the morning of June 22, 2019, astronauts in the ISS captured the plume of ash and gases rising from the erupting Raikoke Volcano on the Kuril Islands in the North Pacific.
Even that susceptibility to disaster is, in fact, quite Earth-like.
A supervolcano eruption or asteroid impact could one day make our planet uninhabitable. That could be the end of life on this Earth, but the research shows there may be plenty more Earth-like planets to spare.

The world’s vast oceans and seas offer seemingly endless spaces in which adversaries of the United States can maneuver undetected. The U.S. military deploys networks of manned and unmanned platforms and sensors to monitor adversary activity, but the scale of the task is daunting and hardware alone cannot meet every need in the dynamic marine environment. Sea life, however, offers a potential new advantage. Marine organisms are highly attuned to their surroundings — their survival depends on it — and a new program out of DARPA’s Biological Technologies Office aims to tap into their natural sensing capabilities to detect and signal when activities of interest occur in strategic waters such as straits and littoral regions.
The Persistent Aquatic Living Sensors (PALS) program, led by program manager Lori Adornato, will study natural and modified organisms to determine which ones could best support sensor systems that detect the movement of manned and unmanned underwater vehicles. PALS will investigate marine organisms’ responses to the presence of such vehicles, and characterize the resulting signals or behaviors so they can be captured, interpreted, and relayed by a network of hardware devices.
“The U.S. Navy’s current approach to detecting and monitoring underwater vehicles is hardware-centric and resource intensive. As a result, the capability is mostly used at the tactical level to protect high-value assets like aircraft carriers, and less so at the broader strategic level,” Adornato said. “If we can tap into the innate sensing capabilities of living organisms that are ubiquitous in the oceans, we can extend our ability to track adversary activity and do so discreetly, on a persistent basis, and with enough precision to characterize the size and type of adversary vehicles.”
Beyond sheer ubiquity, sensor systems built around living organisms would offer a number of advantages over hardware alone. Sea life adapts and responds to its environment, and it self-replicates and self-sustains. Evolution has given marine organisms the ability to sense stimuli across domains — tactile, electrical, acoustic, magnetic, chemical, and optical. Even extreme low light is not an obstacle to organisms that have evolved to hunt and evade in the dark.
However, evaluating the sensing capabilities of sea life is only one of the challenges for PALS researchers. Performer teams supporting DARPA will also have to develop hardware, software, and algorithms to translate organism behavior into actionable information and then communicate it to end users. Deployed hardware systems operating at a standoff distance of up to 500 meters must collect signals of interest from relevant species, process and distill them, and then relay them to remote end users. The complete sensing systems must also discriminate between target vehicles and other sources of stimuli, such as debris and other marine organisms, to limit the number of false positives.
Adornato is aiming to demonstrate the approach and its advantages in realistic environments to convey military utility.
“Our ideal scenario for PALS is to leverage a wide range of native marine organisms, with no need to train, house, or modify them in any way, which would open up this type of sensing to many locations,” Adornato said.
DARPA favors proposals that employ natural organisms, but proposers are able to suggest modifications. To the extent researchers do propose solutions that would tune organisms’ reporting mechanisms, the proposers will be responsible for developing appropriate environmental safeguards to support future deployment. However, at no point in the PALS program will DARPA test modified organisms outside of contained, biosecure facilities.
DARPA anticipates that PALS will be a four-year, fundamental research program requiring contributions in the areas of biology, chemistry, physics, machine learning, analytics, oceanography, mechanical and electrical engineering, and weak signals detection.

Nobody wants to be the weakest troop in their unit. Some people are naturally gifted with the ability to put on layers of muscle quickly, while others spend hours in the gym to grow a single fiber.
However, natural ability aside, many newbies who go to the gym don’t know how to properly lift a weight or how many reps they should be doing in each set.
In general, certain muscle groups are easier to bulk up than others. One common problem area is the shoulders. Considered a weak joint, properly developing definition in the shoulder is best done by emphasizing form over heft.
There are a lot of advanced exercises in the workout vault, but beginners can get away with doing a few of these basic weighted movements to get those healthy-looking shoulders.
Seated overhead dumbbell press
The exercise allows you to use all three of your shoulder muscles at once. As an added bonus, this compound movement also works out your triceps. Sit down, grab some weights you’re comfy with and settle into a position with the weights lifted to about your ears, elbows bent at a 90-degree angle. Then, push up.
Make sure that you don’t lock your elbows out at the top of the rep. That’s bad for your joints and we want to avoid injury. So, always keep a slight bend in your elbow. After the rep, don’t use gravity to lower the weights. Instead, use your shoulder muscles to slowly lower the weight back to the original position.
Cool? Now go and do eight to twelve more, followed up by two to three more sets.
Plate press out
This one doesn’t requires a barbell, just a weighted plate heavy enough to challenge you. All you need to do is grab onto a weighted plate, usually gripping around 9 and 3 o’clock, and hold it close to your chest. Then, extend your arms out parallel to the deck and slowly bring it back in.
Cool? Now go and do eight to twelve more and follow it up with two to three additional sets.
For a lateral raise, you’re not going to need a lot of weight, so don’t use this movement to impress any girls or guys at the gym. Begin by sitting or standing up straight whiling holding a workable weight in each hand down by your sides (near your hips). Once you’re ready to start the rep, raise your hands up and away from your body to each side until your arms are parallel and lower slowly.
You’ll want to do two to three sets of eight to twelve.
You know when your first sergeant gives a lousy order and you shrug your shoulders out of silent, out-of-sight protest? It’s the same thing, but this time you have a manageable weight in your hands.
Cool? Now go and do eight to twelve more of those f*ckers and follow it up with two to three more sets.
Rear delt flys
Now it’s time to bend over and work the rear shoulder muscles, also known as your posterior deltoids. While using those same manageable weights, start in a static position, kick the weight back by rotating your thumbs downward like you’re pouring Patron into a shot glass, then slowly return to the starting position.
Got it? Good. Now go and do eight to twelve more, followed up by another two-to-three sets.
Remember, control and form are everything while trying to build muscle.
