Human Cell Atlas achieves leap in the understanding of the human body
Researchers with the global Human Cell Atlas (HCA) consortium report significant progress in their quest for a better understanding of the cells of the human body in health and disease, with the publication on 20 November of a collection of more than.....»»
Structural analysis reveals how human eyelashes promote water drainage
Throughout human evolution, body and facial hair have notably diminished, yet eyelashes have remained a distinguishing feature. The physiological or functional purpose of eyelashes—traditionally thought to be for catching dust or filtering air—ha.....»»
Discovery of enzyme pathway may lead to lifesaving leishmaniasis treatments
A breakthrough in understanding how a single-cell parasite makes ergosterol (its version of cholesterol) could lead to more effective drugs for human leishmaniasis, a parasitic disease that afflicts about 1 million people and kills about 30,000 peopl.....»»
Inequality weakens local governance and public satisfaction, study finds
Local governments in developing countries are crucial for providing public services that promote human development and address challenges like extreme weather, unemployment and crumbling infrastructure. Yet, they often face difficulties in implementi.....»»
Neutrality has played a pivotal, but under-examined, role in international relations, new research shows
Researchers have developed a new way of understanding international relations by analyzing almost 200 years of alliances, hostilities and neutrality between countries......»»
Researchers take "significant leap forward" with quantum simulation of molecular electron transfer
Researchers at Rice University have made a meaningful advance in the simulation of molecular electron transfer—a fundamental process underpinning countless physical, chemical and biological processes. The study, published in Science Advances, detai.....»»
New AA-powered AirTag case promises 10-year lifespan

Heterogeneous host populations drive evolution of more virulent pathogens, modeling study shows
The evolution of pathogens has received attention in a wide range of scientific fields, such as epidemiology, demography, and evolutionary ecology. Understanding pathogen evolution is particularly urgent for rapidly evolving pathogens, such as SARS-C.....»»
Mitigating animal-vehicle collisions with field sensors, AI and ecological modeling
Collisions between animals and vehicles are a threat to conservation efforts and human safety, and have a massive cost for transport infrastructure managers and users......»»
Biosensors mimic human olfactory system to discriminate between very similar odors
The human olfactory system discriminates between thousands of odors by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different intensities, and the same odorant can activate more th.....»»
The technosphere: A hidden long-term carbon sink in everyday items
We know a lot about how much fossil-derived carbon is emitted to the atmosphere but less about how much is stored in human-made products......»»
Dual-comb method achieves first precise absolute distance measurement over 100 km
A team of physicists and engineers at China's Hefei National Laboratory has succeeded in conducting the first instance of precise absolute distance measurement over a path exceeding 100 km. The group has written a paper describing how they achieved s.....»»
Chang"e-6 farside basalts reveal a reinforced lunar dynamo
The evolution of the lunar dynamo is crucial for understanding the moon's deep interior structure, thermal history, and surface environment. A study by Chinese scientists conducted paleomagnetic analyses on basalts returned by the Chang'e-6 mission a.....»»
Most precise measurement of electrically neutral beauty meson lifetime achieved
The ATLAS collaboration at the Large Hadron Collider (LHC) has released a new high-precision measurement of the lifetime of the electrically neutral beauty (B0) meson—a hadron composed of a bottom antiquark and a down quark......»»
By looking at individual atoms in tooth enamel, researchers are learning what happens to our teeth as we age
Teeth are essential for helping people break down the food they eat, and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away. Unlike other materials in the body, enamel has no way to repa.....»»
Scientists achieve collective quantum behavior in macroscopic oscillators
Quantum technologies are radically transforming our understanding of the universe. One emerging technology is macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications. In the q.....»»
Molecular tool demonstrates how bad eggs are identified for destruction by reproductive system
The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs with chromosomal abnormalities. For years, cell biologists have sought to uncover the mechanisms behind this system, relying on.....»»
Climate change could trigger more earthquakes, study suggests
A recent Colorado State University study published in the journal Geology demonstrates that climate change can affect the frequency of earthquakes, adding to a small but growing body of evidence showing that climate can alter the seismic cycle......»»
Apollo lunar mission samples reveal origins of lunar water and its connection to Earth"s early history
A team of international scientists has unveiled groundbreaking research on the origins of lunar water, offering insights that could reshape our understanding of the Earth-moon system and the broader solar system. Published in the journal Proceedings.....»»
Cellular RNA plays key role in antiviral defense, study finds
Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune re.....»»
Call to ban Apple Intelligence summary feature after Luigi Mangione error
The Apple Intelligence summary feature should be banned after it falsely claimed that Luigi Mangione had shot himself, says Reporters Sans Frontières (RSF). The non-profit body advises the United Nations, Council of Europe, and other governmental.....»»
