The famous 1700 Cascadia earthquake that altered the coastline of western North America and sent a tsunami across the Pacific Ocean to Japan may have been one of a sequence of earthquakes, according to new research.

A chemist has found a way to synthesize a compound to fight a previously 'undruggable' cancer protein with benefits across a myriad of cancer types.

An expansive project is examining the benefits, and limits, of environmental restoration on developed land after humans are done with it.

Concern tends to ratchet up a notch when pollution enters the river runoff discussion on a national scale, specifically when smaller, navigable intrastate bodies of water push pollution into larger interstate waters often involved in commerce (i.e. the Mississippi River, Great Lakes, Ohio River).

Mass extinctions are known as times of global upheaval, causing rapid losses in biodiversity that wipe out entire animal groups. Some of the doomed groups linger on before going extinct, and a team of scientists found these 'dead clades walking' (DCW) are more common and long-lasting than expected.

Using a widely known field of mathematics designed mainly to study how digital and other forms of information are measured, stored and shared, scientists say they have uncovered a likely key genetic culprit in the development of acute lymphoblastic leukemia (ALL).

As artificial intelligence has attracted interest, researchers are focused on understanding how the brain accomplishes cognition so they can construct systems with general intelligence comparable to humans' intelligence. Researchers propose an approach to AI that focuses on integrating photonic components with superconducting electronics; using light for communication and complex electronic...

Researchers have uncovered a new approach to structural topology optimization is outlined that unifies both design and manufacturing to create novel microstructures. Potential applications range from improved facial implants for cranial reconstruction to better ways to get materials into space for planetary exploration.

Fiber optic technology is the holy grail of high-speed, long-distance telecommunications. Still, with the continuing exponential growth of internet traffic, researchers are warning of a capacity crunch. Researchers show how quantum-enhanced receivers could play a critical role in addressing this challenge. The scientists developed a method to enhance receivers based on quantum physics properties...

Earthquake early warnings can be delivered successfully using a small network of off-the-shelf smartphones attached to building baseboards, according to a study conducted in Costa Rica last year.

Astronauts who spend prolonged time alone in space face mental health stressors like loneliness, isolation and more. A psychologist developed the Mental Health Checklist, a self-reporting instrument for detecting mental health changes in isolated, confined, extreme environments. She's reporting results that show significant declines in positive emotions.

To search for answers about how blood droplets from a gunshot wound can reverse direction while in flight, researchers explored the influence of propellant gases on blood backspatter. They report using numeric modeling to capture the behavior of gun muzzle gases and predict the reversal of blood droplet flight, which was captured experimentally. Their experiments also show the breakup of blood...

A real-life forensic puzzle inspired researchers to explore the physics involved, and in Physics of Fluids, they present theoretical results revealing an interaction of the incoming vortex ring of propellant muzzle gases with backward blood spatter. A detailed analytical theory of such turbulent self-similar vortex rings was given by this group in earlier work and is linked mathematically to the...

Scientists reveal several key factors that influence the number of bounces a skipping stone will undergo when hitting the water. The study involved theoretical modeling and an experimental setup using a model stone to gather data in real time and that allowed a motor to apply a controlled spin to the disk prior to launch. The investigators found that vertical acceleration and the spin direction...

Artificial intelligence (AI) can analyze large amounts of data, such as those generated when analyzing the properties of potential new materials, faster than humans. However, such systems often tend to make definitive decisions even in the face of uncertainty; they overestimate themselves. An international research team has stopped AI from doing this: the researchers have refined an algorithm so...

Researchers found a cause for severe epilepsy resulting in death in Parson Russell Terrier puppies at a few months of age. A change in the PITRM1 gene can lead to a dysfunction of mitochondria, the cellular energy pumps. Concurrently, amyloid-beta accumulation and widespread neurodegeneration associated with Alzheimer's disease were identified in the puppies' brains. Changes to the PITRM1 gene in...

Exposure to certain endocrine-disrupting chemicals could elevate the risk of breast cancer, according to a new comprehensive systematic review of epidemiological research. However, for many chemicals, evidence is inconsistent or still limited.

Perovskites have so far been used for solar cells, as anode materials or electronic components rather than for their catalytic properties. Now scientists have succeeded in producing a special perovskite that is excellently suited as a catalyst for converting CO2 into other useful substances, such as synthetic fuels. The new perovskite catalyst is very stable and also relatively cheap, so it would...

In extreme heat or in the vacuum of space: a novel nanomaterial delivers top performance in extreme situations.

Using data from the Human Cell Atlas, researchers have identified the differences in immune cells' response in those who had no symptoms compared to severe symptoms.

An international group of scientific experts has stated the requirements for coral reef survival in a recent article. Over 500 million people rely on coral reefs.

Researchers compared the R (basic reproduction number) of the original SARS-CoV-2 virus with the R of the British variant, and found that the British variant is almost 1.5 times more infectious.

Genetically engineered animals provide important insights into the molecular basis of health and disease. Research has focused mainly on genetically modified mice, although other species, such as pigs, are more similar to human physiology. Researchers have now generated chickens and pigs in which target genes in desired organs can be efficiently altered.

Frequent use of social media may not amount to the same as addiction, according to new research.
