Space debris poses growing threat, but new study suggests cleanup is feasible
High up in Earth's orbit, millions of human-made objects large and small are flying at speeds of over 15,000 miles per hour. The objects, which range from inactive satellites to fragments of equipment resulting from explosions or collisions of previously launched rockets, are
Quantum technology moves from lab to life, but widespread use remains years away
Quantum technology is accelerating out of the lab and into the real world, and a new article argues that the field now stands at a turning point—one that is similar to the early computing age that preceded the rise of the transistor and modern computing.
A new look at TRAPPIST-1e, an Earth-sized, habitable-zone exoplanet
Of the seven Earth-sized worlds orbiting the red dwarf star TRAPPIST-1, one planet in particular has attracted the attention of scientists. This planet orbits the star within the "Goldilocks zone"—a distance where water on its surface is theoretically possible, but only if the
Astrophysicists test a new piece of the sky to probe dark matter and dark energy
In the leading model of cosmology, most of the universe is invisible: a combined 95% is made of dark matter and dark energy. Exactly what these dark components are remains a mystery, but they have a tremendous impact on our universe, with dark matter exerting a gravitational

Q&A: Why understanding stem cells is the root of treating diseases from psoriasis to cancer
Your skin is in a constant state of reinvention. Every month, your body sheds and regenerates its entire outer layer—a complete turnover powered by tiny, tireless stem cells. These same cells spring into action when you get a cut, healing wounds with remarkable speed.
Frequent flares from TRAPPIST-1 could impact habitability of nearby planets
Like a toddler right before naptime, TRAPPIST-1 is a small yet moody star. This little star, which sits in the constellation Aquarius about 40 light-years from Earth, spits out bursts of energy known as "flares" about six times a day.
Ultrasonic pest control can protect beehives
Bees, and other pollinator species, are dying. Between pesticides, the climate crisis, and habitat loss, bee colonies are becoming weaker, leaving them more vulnerable to parasites like the greater and lesser wax moths. Vulnerable bees have cascading effects on beekeepers and

Cracking the code of why and when some choose to 'self-handicap'
Partying the night before a big exam. Preparing last-minute for a work presentation. Running a 5K in a 10-pound Halloween costume. All are examples of what psychologists call "self-handicapping"—creating obstacles to success to order to bolster or protect one's own reputation.
Seeding jet exhaust with ice-nucleating particles could reduce aviation's climate impact
If you look up at the sky on a clear day, chances are you'll notice thin, white clouds—also known as contrails—following behind airplanes.

University of Pittsburgh researchers have made an important step toward providing hospitals and water treatment facilities with a safer, greener alternative to chlorine-based disinfection.
Researchers find promising adaptations to climate change in tropical forests
As tropical forests experience chronic drying and more extreme droughts due to climate change, some plants are adapting by growing longer root systems to reach water deep within soils, according to a study published in November in New Phytologist.
New statistical tools sharpen the search for causal DNA changes in livestock
Researchers at North Carolina State University have developed a new suite of statistical methods that dramatically improves the ability to pinpoint DNA changes responsible for important traits in livestock. The work addresses long-standing challenges in fine-mapping—the process
