Phys.org / Radiocarbon dating rewrites angiosperm trees' lifespan records worldwide

For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many flowering trees—sometimes ...

Phys.org / Wildlife imaging shows that AI models aren't as smart as we think

Using AI to identify wildlife reveals a potential "transferability crisis," researchers say. Marketing for AI imaging systems often suggests that models can easily tackle novel scenarios across ecosystems and settings, much ...

Phys.org / Discovery of natural mechanism behind ferroptosis solves longstanding puzzle in cell biology

After more than a decade of research, scientists have discovered the natural mechanism behind a novel form of cell death called ferroptosis. The work, described in the current issue of Cell, points toward an entirely new ...

Phys.org / Rewilding could fill gap left by Panama's lost giants

Many large herbivores that once roamed modern-day Panama have declined or died out—including the 6-meter-long giant ground sloth and elephant-related creatures called Cuvieronius. New research suggests that introducing ...

Phys.org / Poking a nanostring: Scientists uncover energy cascades in tiny resonators

Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. ...

Phys.org / Brain structure volume linked to increased social tolerance in macaques

Researchers have found that the size of the amygdala—a region of the brain involved in processing emotions—could be linked to social tolerance in macaque monkeys. Their research, published today in eLife, is described ...

Phys.org / Studying snakes' ability to stand upright could inform soft robotics and more

Snakes may be best known for slithering. But consider that these animals also perform one of the most extreme feats of posture control found in nature: They can stand nearly straight upright on a narrow perch without falling, ...

Phys.org / Newly excavated Maya wetland settlement shows the civilization's adaptation to changing climate

Past civilizations have been significantly affected by climate change, but how they adapted to new conditions centuries ago is less clear. In research newly published in the Proceedings of the National Academy of Sciences, ...

Phys.org / Paternal mitochondria in plants can rescue defective maternal DNA, study reveals

In most plants and animals, including humans, mitochondria are inherited exclusively, or nearly exclusively, from the mother. By contrast, paternal transmission is observed only occasionally, and the mechanisms behind this ...

Phys.org / Four decades of data give unique insight into the sun's inner life

Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their findings in Monthly Notices ...
