Scientists have for the first time quantified how warming coastal waters are impacting individual glaciers in Greenland's fjords. Their work can help climate scientists better predict global sea level rise from the increased melting.
In a brain with a neurological disorder like epilepsy, synchronization between groups of neurons can grow to a dangerous extent when a collection of brain cells begins to emit excess electricity. Researchers used a mathematical model to explore the interplay between neurons that leads to these transitions in synchronization during the onset of seizures.
Astrocytes are the most abundant type of cells within the central nervous system (CNS), but they remain poorly characterized. Researchers have long assumed that astrocytes' primary function is to provide nutrients and support for the brain's more closely scrutinized nerve cells; over the years, however, increasing evidence has shown that astrocytes can also actively promote neurodegeneration, inflammation, and neurological diseases.
The TOI-178 planetary system, a 7.1-billion-year-old system of six planets in the super-Earth to mini-Neptune range, five of which are locked in a rare rhythm around their parent star, could provide important clues about how planets form and evolve. TOI-178 is a K-type star located approximately 205 light-years away in the constellation of Sculptor. Otherwise [...]
The enzymes in human cells known as histone deacetylases, or HDACs, are targets for a handful of anticancer drugs because of their ability to affect gene expression. Now, researchers have developed a new method to investigate how these enzymes work on a molecular level. This new method can also help identify more precise possible anti-cancer drug candidates at a very high pace.
Special immune cells found in the brain, microglia, play a key role in the processes that make you feel uneasy and depressed in correlation with inflammation. This is the conclusion of a study using mice. The results suggest that microglial cells contribute to the negative mood experienced during several neurological diseases, and maybe also depression.
Nature is full of color. For flowers, displaying color is primarily a means to attract pollinators. Insects use their color vision not only to locate the right flowers to feed on but also to find mates. The evolutionary interaction between insects and plants has created complex dependencies that can have surprising outcomes.
Neuroscientists and engineers have developed a system that can show the neural process of decision making in real time, including the mental process of flipping between options before expressing a final choice.
A new theory that could explain how unconventional superconductivity arises in a diverse set of compounds might never have happened if a team of physicists had chosen a different name for their 2017 model of orbital-selective superconductivity.
NASA's Roman Space Telescope will conduct a microlensing survey to reveal worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme planets and planet-like bodies in the heart of the galaxy, thanks to their gravitational tug on the stars they orbit.
A 1,500-year-old inscription that reads ‘Christ, born of Mary’ has been discovered by a team of archaeologists from the Israel Antiquities Authority (IAA). The early Christian inscription, written in ancient Greek, was found in the village of et-Taiyiba in the Jezreel Valley. It comes from the frame of an entrance door of the Byzantine-period (5th [...]
Researchers have developed an automated way to design customized hardware that speeds up a robot's operation. The system, called robomorphic computing, accounts for the robot's physical layout in suggesting an optimized hardware architecture.
A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to stabilize it with pressure from a diamond anvil cell. The required pressure is well within the reach of industrial manufacturing requirements.
A cross-cultural analysis found several factors may have played a role in building the relationship between humans and dogs, including temperature, hunting and surprisingly - gender. The analysis used ethnographic information from 144 traditional, subsistence-level societies from all over the globe. People were more likely to regard dogs as a type of person if the dogs had a special relationship with women -- such as having names and being treated as family.
A world-first discovery could become a game-changer for patients at risk of rapid health deterioration, such as heart complications, stroke, sepsis and cancer. Researchers developed an antibody as a biosensor, to continuously monitor rapid changes in the concentration of EGFR, a protein present on cancer cells and in body fluids.
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a new study. The research shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy - at least in the equatorial Pacific.
An international team of researchers has developed a new method to better understand how nanomedicines -- emerging diagnostics and therapies that are very small yet very intricate -- interact with patients' biomolecules.
Scientists have identified a key nutrient source used by algae living on melting ice surfaces linked to rising sea levels. They discovered that phosphorus containing minerals may be driving ever-larger algal blooms on the Greenland Ice Sheet.
The rate at which ice is disappearing across the planet is speeding up, according to new research. And the findings also reveal that the Earth lost 28 trillion tons of ice between 1994 and 2017 - equivalent to a sheet of ice 100 meters thick covering the whole of the UK.
