New research reaffirms that human footprints found in White Sands National Park, NM, date to the Last Glacial Maximum, placing humans in North America thousands of years earlier than once thought.  In September 2021, scientists announced that ...
Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light. This observation is hard to ...
Scholars have discovered evidence of a sixth basic taste. The tongue responds to ammonium chloride, a popular ingredient in some Scandinavian candies. The OTOP1 protein receptor, previously linked to sour taste, is activated by ammonium chloride. ...
Researchers have produced an engineered tissue representing a simplified cerebral cortex by 3D printing human stem cells. When implanted into mouse brain slices, the structures became integrated with ...

A new study has found that people may experience long-term symptoms -- or 'long colds' -- after acute respiratory infections that test negative for ...

Structural patterns can be created due to the chasing interactions between two bacterial species. In a new model, scientists describe how interactions on the individual level can result in a global ...

A team of computer scientists has created a neural network that can explain how it reaches its predictions. The work reveals what accounts for the functionality of neural networks--the engines that ...

Researchers have discovered the master regulator responsible for balancing the expression of X chromosome genes between males and females in the malaria mosquito. This discovery helps scientists ...

Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, ...

Researchers have identified a 'guard mechanism' for a protein which attacks microbes in infected cells, opening the possibility of new treatments for Toxoplasma, Chlamydia, Tuberculosis and ...

Researchers found that pre-existing immunity to Cytomegalovirus (CMV) can limit its transmission during pregnancy and protect against associated birth defects. The study marks an important step ...

Researchers have shown that pregnancy hormones ‘rewire’ the brain to prepare mice for motherhood. The findings show that both estrogen and progesterone act on a small population of neurons in the ...

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in ...

Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...

A new attempt to predict earthquakes has raised hopes that artificial intelligence could one day be used to limit earthquakes’ impact on lives and economies. The AI algorithm correctly predicted ...

New research shows that plants such as oak and poplar trees will emit more of a compound called isoprene as global temperatures climb. Isoprene from plants represents the highest flux of hydrocarbons ...

When we’re married or in a long-term romantic relationship, we may eventually come to take each other for granted and forget to show appreciation. A new study finds that it doesn’t have to stay ...

Imagine a life form that doesn't resemble any of the organisms found on the tree of life. One that has its own unique control system, and that a doctor would want to send into your body. It ...

Physicists have experimentally detected how so-called Hubbard excitons form in ...

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity ...

Researchers play ultra-brief tones to stimulate the brain during deep sleep. This stimulation improves cardiac output and relaxation of the left ventricle. Such technology to improve cardiovascular ...

As we age, many of us will eventually need hearing aids. In some cases, the reason for this may be a signaling pathway that controls auditory sensory cell function and is downregulated with ...
