Toxins released by a type of bacteria that cause diarrheal disease hijack cell processes and force important proteins to assemble into "roads to nowhere," redirecting the proteins away from other jobs that are key to proper cell function, a new study has found.

Rapid changes in marine oxygen levels may have played a significant role in driving Earth's first mass extinction, according to a new study led by Florida State University researchers.

Depending on age, humans need 7 to 13 hours of sleep per 24 hours. During this time, a lot happens: Heart rate, breathing and metabolism ebb and flow; hormone levels adjust; the body relaxes. Not so much in the brain.

A new study has revealed the true shape of the diffuse cloud of stars surrounding the disk of our galaxy. For decades, astronomers have thought that this cloud of stars—called the stellar halo—was largely spherical, like a beach ball. Now a new model based on modern observations shows the stellar halo is oblong and tilted, much like a football that has just been kicked.

Researchers discuss how mimicking sleep patterns of the human brain in artificial neural networks may help mitigate the threat of catastrophic forgetting in the latter, boosting their utility across a spectrum of research interests.

Triple threat. Tripledemic. A viral perfect storm. These frightening phrases have dominated recent headlines as some health officials, clinicians, and scientists forecast that SARS-CoV-2, influenza, and respiratory syncytial virus (RSV) could surge at the same time in Northern Hemisphere locales that have relaxed masking, social distancing, and other COVID-19 precautions. But a...

China has made few friends lately with the serial, uncontrolled reentries of the spent first stages of its Long March 5B spacecraft, which have posed potential threats to populations on the ground. Now, as the South China Morning Post reports, a Chinese rocket has created yet another mess—this time in orbit 500 km (310 mi.) above Earth, at an altitude that could imperil SpaceX’s...

A study has found that anti-hyperglycemic medications used to treat Type 2 diabetes resulted in an increased risk of multiple sclerosis for people older than 45, particularly among women.

A new isotope labeling and catalyst quenching-based direct visualization technique was developed to explain the oxygen storage and release process in three-way catalysts (TWCs) used in vehicular exhaust treatment systems.

New data throws out the textbook picture of a spherical stellar halo and reinforces a dynamic origin story of two galaxies that collided billions of years ago.

Fruit flies can quickly compensate for catastrophic wing injuries, researchers found, maintaining the same stability after losing up to 40% of a wing. This finding could inform the design of versatile robots, which face the similar challenge of having to quickly adapt to mishaps in the field.

Researchers developed a technique to effectively measure the thermal expansion coefficient of two-dimensional materials. With this information, engineers could more effectively and efficiently use these atomically-thin materials to develop next-generation electronic devices that can perform better and run faster than those built with conventional materials.

The flash Joule heating process turns asphaltenes, a byproduct of crude oil production, into graphene for use in composite materials.

A research team showed how drugs can reduce alcohol preference in animal models of post-traumatic stress disorder.

Inspired by the biomechanics of the manta ray, researchers have developed an energy-efficient soft robot that can swim more than four times faster than previous swimming soft robots. The robots are called 'butterfly bots,' because their swimming motion resembles the way a person's arms move when they are swimming the butterfly stroke.

Second added periodically to synchronise atomic time and Earth time can cause problems for GPS systems, software and telecomsScientists and government representatives meeting at a conference in France have voted to scrap leap seconds by 2035, the organisation responsible for global timekeeping has said.Similar to leap years, leap seconds have been periodically added to clocks over the last half...

Astronomy is driven by big questions, and they don't come much bigger than wondering how the first stars and galaxies began to form—eventually giving rise to our own existence.

Researchers of the University of Malaga (UMA) and the University of Jaen (UJA) have discovered Egypt's oldest tomb oriented to the winter solstice. Located in the necropolis of Qubbet el-Hawa (Aswan), it is precisely oriented to the sunrise of the winter solstice, in such a way that the sun's rays bathed with its light the place that was intended to house the statue of a governor of the city of...
