NASA is crashing a spacecraft into an asteroid to test a plan that could one day save Earth from catastrophe

On Sept. 26, 2022, NASA plans to change an asteroid’s orbit.

The large binary asteroid Didymos and its moonlet Dimorphos currently pose no threat to Earth. But by crashing a 1,340-pound (610-kilogram) probe into Didymos’ moon at a speed of approximately 14,000 mph (22,500 kph), NASA is going to complete the world’s first full-scale planetary defense mission as a proof of concept. This mission is called the Double Asteroid Redirection Test, or DART.

Super-Earths are bigger, more common and more habitable than Earth itself – and astronomers are discovering more of the billions they think are out there

Astronomers now routinely discover planets orbiting stars outside of the solar system – they’re called exoplanets. But in summer 2022, teams working on NASA’s Transiting Exoplanet Survey Satellite found a few particularly interesting planets orbiting in the habitable zones of their parent stars.

One planet is 30% larger than Earth and orbits its star in less than three days. The other is 70% larger than the Earth and might host a deep ocean. These two exoplanets are super-Earths – more massive than the Earth but smaller than ice giants like Uranus and Neptune.

HIV therapies currently need to be taken regularly for life – longer-lasting antibody treatments could one day offer an equally effective one-shot alternative

Antiretroviral therapy has had an enormous impact on treating HIV infections around the world. The millions of people currently taking these treatments under medical supervision can reasonably expect to reduce their viral loads to undetectable levels, eliminate the risk of transmission and live a normal life span. However, antiretroviral therapy is not without shortcomings. People need to take these medications regularly for life, and low compliance can lead to drug resistance.

There is a promising new option on the horizon. I am a researcher who studies AIDS treatments, and I believe that monoclonal antibodies could become game-changers for the treatment of HIV infections.

Trump with 'large group' at Virginia golf club — but 'not appearing to play'

The internet went wild with speculation Sunday evening, with even top attorneys making law jokes after Donald Trump was seen getting off a private plane at Dulles International Airport outside Washington, D.C., wearing golf shoes and casual attire.

Some on social media insisted that he was being arrested, or there was a sealed indictment awaiting him, while others speculated he might be attending his son-in-law's private fundraising dinner, but all those guesses – or wishful thinking by some – were apparently false.

Your mighty tendons help you sprint, jump and move – a genetic mutation in one key protein may increase athletic performance

The ability to move is an essential part of daily life. The locomotor, or musculoskeletal, system of the body consists of muscles, bones, tendons, ligaments, joints, cartilage and other connective tissue. Loss of motor function due to disease or injury can result in a lifetime of disability. In a rapidly aging society, maintaining and improving motor function can be a significant challenge for many people.

But there are ways to get around motor failure. As molecular biologists and orthopedic surgeons who study the locomotor system, we believe one key part of it has been underestimated – the tendons.

A seismic change has taken place at the Supreme Court

In the summer of 2022, the U.S. witnessed a dramatic change in how the majority of Supreme Court justices understand the Constitution.

At the end of a single term, the court rejected the long-standing constitutional right to abortion, expanded gun rights and ruled that religion can have a bigger role in public institutions.

Ukraine war: Russia’s problems on the battlefield stem from failures at the top

For authoritarians like the Russian president, Vladimir Putin, the military can serve a number of functions. Not only is it a key aspect of maintaining control and projecting power, but in Putin’s case it has served as a key national resource to plunder for personal wealth and to enrich key allies. Yet while the military is a key pillar that keeps his regime in power, Putin is also conscious of the threat it could pose to his role.

Since taking power, Putin has instituted a range of measures to maintain oversight and control over the Russian state, with the military being no exception. While this approach helps him keep his grip on power, it is not without drawbacks. Indeed, the rigid and inflexible command structure hampering Russian forces on the battlefield can be linked back to both Putin’s coup-proofing efforts and attitudes left over from the nation’s Soviet past.
