Eight signals from far-off stars probably aren't aliens, but the machine learning method that found them holds promise in the search for real extraterrestrials.

Researchers have identified two distinct processes that are triggered in the brain when a person is exposed to prolonged or repeated sensory input.

Glucose takes longer to get into the nucleus accumbens of obesity-prone rat models. Researchers also discovered excess levels of glutamate in obesity-prone rats, implying a deficiency in the neurotransmitter recycling pr...

An eye drop product linked to a cluster of serious bacterial infections has been voluntarily recalled by its manufacturer.

When molecules form from many atoms, the atoms can combine in different ways. Two forms of the same molecule can have the same composition but have different arrangements of atoms, giving rise to isomers. Some isomers ma...

The advent of intense ultrashort coherent light pulses has revolutionized the spectroscopy field. They allow easy observation of various nonlinear optical effects and facilitate the characterization of materials with non...

Over eighty years ago, Rabi oscillations were proposed to describe the strong coupling and population transfer in a two-level quantum system exposed to an oscillatory driving field. As compared to atoms, molecules have a...

Researchers at Purdue University have made a groundbreaking discovery in the field of thermal radiation, uncovering a new method for generating spinning thermal radiation in a controlled and efficient manner using artifi...

From step rates to stride lengths, here's everything you need to know about cadence in running.

Nestled in the mountains of western South Dakota is the little town of Lead, which bills itself as "quaint" and "rough around the edges." Visitors driving past the hair salon or dog park may never guess that an unusual--...

As plasma circulates in a fusion device, the surface of the device that faces the plasma erodes. This releases particles of surface material. Most erosion occurs through a process called sputtering, where a particle stri...

Some 540 million years ago, diverse life forms suddenly began to emerge from the muddy ocean floors of planet Earth. This period is known as the Cambrian Explosion, and these aquatic critters are our ancient ancestors. A...

Grab a student laptop bargain as Best Buy slashes the price of the MacBook Air M1.

A new material changes its infrared colour when a small electric current is applied, raising the possibility of buildings that store or release heat depending on outside temperatures

Many historians consider the fall of the Western Roman Empire to have been when the emperor Romulus Augustulus abdicated, but not all historians agree.

Receiving more intensive treatment for high blood pressure results in positive alterations in brain structures associated with clearing toxins and other by-products. Findings reveal intensive blood pressure treatments ca...

Researchers report people who share political ideologies have similar neural fingerprints when it comes to political words and process new information in similar ways. The study shows how polarization arises at the point...

Natural resistance to capsaicin's effect in birds drove researchers to investigate a specific genetic variant that appears to be associated with pain resistance. They discovered the K710N human variant dialed down pain a...

A new method dubbed STARmap PLUS was utilized to track and map changes in tau and amyloid beta in the brain as Alzheimer's disease progressed in mouse models.
