Ancient Mongolian cemetery reveals power and status mattered more than blood ties‎

On the edge of the Mongolian steppe, overlooking where two rivers meet, lies an ancient cemetery. Buried within are two families, traced through ancient DNA across six generations, surrounded by dozens of "strangers." The obvious assumption is that this was a family cemetery. But a recent study used machine learning and a technique borrowed from evolutionary biology to reveal that what really mattered was wealth, status and political power, not blood.

How much clothing is too much? The math behind having a sustainable wardrobe‎

Most people suspect they own too many clothes, but they aren't sure exactly what the "right amount" is. Recent wardrobe studies, in which researchers literally peek inside people's closets, show the scale of the problem is far greater than most of us imagine.

Faster aptamer screening finds synthetic alternatives to antibodies in days instead of months‎

Aptamers are short DNA or RNA strands that can recognize and bind to a specific target molecule with high precision. Similar to antibodies, they can be used to detect these molecules or modulate their activity. Unlike antibodies, they are much more stable, can be produced synthetically and can be chemically modified to achieve the desired properties. As a result, they can offer capabilities that cannot be achieved with antibodies.

Pumice rafts encroach on Admiralty Islands‎

On May 8, 2026, satellites detected signs of an unexpected submarine volcanic eruption in the Bismarck Sea near the islands of Papua New Guinea. Over the next several weeks, plumes of steam and ash streamed over the sea, and areas of discolored water surrounded the eruption site. Relatively little is known about the ocean floor in this area or the volcanic feature that is presently erupting. But experts think the new activity, ongoing as of mid-June, might be occurring along the Titan Ridge and has the potential to form an ephemeral new island.

Antarctica is offering 30 to 50 years' worth of warning on sea level rise, models suggest‎

Scientists predict that the next three to five decades provide a critical window to anticipate and plan for Antarctic ice loss and its contribution to sea level rise. Research published in Nature, led by Monash University researcher Dr. Felicity McCormack from Securing Antarctica's Environmental Future (SAEF), looks at the predictability of Antarctic ice loss and what this means for sea level rise projections.

Australian farmers are desperate to escape the latest mouse plague—and may soon get relief‎

For months, a flood of mice has engulfed Western Australia's agricultural regions. For people living through it, this latest mouse plague is all-consuming. Houses, sheds, paddocks and roads are blanketed with mice. And the smell of mice, both dead and alive, is impossible to escape.

Novel generative AI model enables atomic-scale prediction of protein-protein interactions‎

Proteins are the molecular workhorses of the human body. They perform a vast range of essential functions, from building tissues and transporting molecules to regulating cellular communication and defending against infection. Many medicines, including antibody therapies for cancer and insulin therapy for diabetes, among many others, work by interacting with specific proteins or by replacing proteins that are missing or malfunctioning. Because proteins carry out so many critical biological tasks, the ability to predict and engineer how they interact with one another could open new possibilities for treating disease.

Landback returns of Indigenous lands happening across country, can lead public planning‎

Land acknowledgments, or statements in which planners, residents or organizations recognize that the land they exist and operate on originally belonged to Indigenous nations, have become increasingly common in recent years. New research from the University of Kansas has found that the landback movement, in which land is returned to its original occupants, has grown rapidly across the country as well.

AI-designed protein unlocks virus-like shells that could reshape vaccine and drug delivery‎

An international research team led by a Korean scientist has succeeded in designing large-scale protein structures that faithfully replicate the self-assembly principles found in naturally occurring viruses, using artificial intelligence (AI).

Training class increases time fathers spend with children and on housework, improving mothers' access to work‎

A one-off training session increased how much time fathers spent with their children and on chores by about two hours a week, reports a new study from the University of Tokyo. A team in Japan provided male employees and their managers with either information on positive office attitudes toward paternity leave or a work-life balance training session. The former corrected common misconceptions, but fathers who attended the training reported real behavioral change. This unexpectedly freed up 3.6 hours of time that mothers used for their own work. The study shows how small workplace interventions can have wider positive impacts for families and businesses.
