Phys.org / Fossil teeth yield 18-million-year-old proteins, offering new clues to mammal evolution
Proteins degrade over time, making their history hard to study. But new research has uncovered ancient proteins in the enamel of the teeth of 18-million-year-old fossilized mammals from Kenya's Rift Valley, opening a window ...
Medical Xpress / Peripheral nerve regeneration driven by hundreds of unknown RNA molecules
Unlike the brain and spinal cord, peripheral nerve cells, whose long extensions reach the skin and internal organs, are capable of regenerating after injury. This is why injuries to the central nervous system are considered ...
Phys.org / Seeking moral advice from large language models comes with risk of hidden biases
More and more people are turning to large language models like ChatGPT for life advice and free therapy, as it is sometimes perceived as a space free from human biases. A new study published in the Proceedings of the National ...
Medical Xpress / A 'Google Maps' for tau movement sheds light on why some brain regions resist Alzheimer's
It's been recognized for some time that Alzheimer's disease affects brain regions differently and that tau—a protein known to misbehave—plays an important role in the disease. Normally, tau helps stabilize neurons, but ...
Phys.org / Climate change and aerosols drive persistent drought and lower rainfall in Southwest, study finds
In the late 2010s, when Assistant Professor Flavio Lehner worked for the National Center for Atmospheric Research in Boulder, Colorado, water managers often asked him about the drought in the Southwest. Was the low precipitation ...
Medical Xpress / Novel AI method sheds light on how enzyme linked to Alzheimer's selects its targets
Researchers from DZNE, Ludwig-Maximilians-Universität München (LMU), and Technical University of Munich (TUM) have found that the enzyme "gamma-secretase"—implicated in Alzheimer's disease and cancer—selects its reaction ...
Phys.org / More phytoplankton in Southern Ocean can help combat global warming
New international research led by Professors Willy Baeyens and Yue Gao of the Vrije Universiteit Brussel (VUB), published in One Earth, demonstrates that plankton is not only the basis of the marine food chain but also a ...
Phys.org / Low-loss spin waveguide network could pave way for energy-efficient AI hardware
The rapid rise in AI applications has placed increasingly heavy demands on our energy infrastructure. All the more reason to find energy-saving solutions for AI hardware. One promising idea is the use of so-called spin waves ...
Phys.org / How the wind shapes the waves: Laser measurements reveal previously hidden interactions above the ocean
An international research team led by the Helmholtz-Zentrum Hereon has, for the first time, succeeded in visualizing and quantifying the complex airflow dynamics directly above the ocean surface in high resolution. Using ...
Medical Xpress / Stepping up the potential of wearables: Predicting pediatric surgery complications
An estimated 4 million children undergo surgical procedures in hospitals across the United States each year. Although postoperative complications, such as infections, can pose significant health risks to kids, timely detection ...
Phys.org / Astronomers investigate pulsar PSR J1930+1852 and its pulsar wind nebula
Using NuSTAR and XMM-Newton satellites, astronomers from New York University (NYU) Abu Dhabi have observed a pulsar known as PSR J1930+1852 and its pulsar wind nebula (PWN). Results of the observational campaign, published ...
Medical Xpress / Largest review of antidepressants to date finds most people do not experience severe withdrawal
The largest review of "gold standard" antidepressant withdrawal studies to date has identified the type and incidence of symptoms experienced by people discontinuing antidepressants, finding most people do not experience ...
