A scientist has discovered a method for detecting and better defining meteorite impact sites that have long lost their tell-tale craters. The discovery could further the study of not only Earth's geology but also that of other bodies in our solar system.
Organic materials could soon be utilized for glow-in-the-dark products, which has the potential to diversify and expand the already US$400 million industry, thanks to new research.
A new international study shows how near-term mitigation can help to prevent an overshoot in global temperatures, thereby reducing climate risks and bringing long-term economic gains.
The Antarctic Circumpolar Current (ACC), the only ocean current that circumnavigates the planet, is speeding up. For the first time, scientists are able to tell that this is happening by taking advantage of a decades-long set of observational records.
Recent research compared the genetic expression profiles of a nonlethal canine tumor and the rare, devastating human oral tumor it resembles, laying the groundwork for potential translational medicine down the road.
Researchers have discovered a new marine reptile. The specimen, a stunningly preserved meter-long skull, is one of the last surviving ichthyosaurs -- ancient animals that look eerily like living swordfish.
Using observations from NASA's ICON mission, scientists presented the first direct measurements of Earth's long-theorized dynamo on the edge of space: a wind-driven electrical generator that spans the globe 60-plus miles above our heads. The dynamo churns in the ionosphere, the electrically charged boundary between Earth and space. It's powered by tidal winds in the upper atmosphere that are faster than most hurricanes and rise from the lower atmosphere, creating an electrical environment that can affect satellites and technology on Earth.
The world's eight most extreme wildfire weather years on record have occurred in the last decade, according to a new study that suggests extreme weather is being driven by a decrease in atmospheric humidity coupled with rising temperatures.
Research has long strived to develop computers to work as energy efficiently as our brains. A study has now succeeded in combining a memory function with a calculation function in the same component. The discovery opens the way for more efficient technologies, everything from mobile phones to self-driving cars.
A recent study in mice has uncovered that during chronic viral infection, a protein called BMI-1 gets turned on too early in B cells and messes up the delicate balance of gene expression, resulting in antibodies that are unsuccessful in their endeavor to clear the virus from the body.
Scientists have discovered a new form of biological reproduction -- and created self-replicating living robots. Made from frog cells, these computer-designed organisms gather single cells inside a Pac-Man-shaped 'mouth' -- and release Xenobot 'babies' that look and move like themselves. Then the offspring go and do the same -- over and over.
Researchers have developed a wearable device to detect and reverse an opioid overdose. The device, worn on the stomach like an insulin pump, senses when a person stops breathing and moving, and injects naloxone, a lifesaving antidote that can restore respiration.
Identical twins share the same DNA, but one twin can suffer from type 2 diabetes while the other twin does not develop the disease. Researchers have now discovered that there are differences in gene activity in twins where only one sibling had developed the disease. The discovery could contribute to the development of new treatment methods.
Poor sleep in the over 50s is linked to more negative perceptions of aging, which in turn can impact physical, mental and cognitive health, new research has revealed. A study found that people who rated their sleep the worst also felt older, and perceived their own physical and mental aging more negatively.
Researchers modeled what happens to respiratory droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smaller, easier-to-spread aerosolized particles.
How can we better diagnose blood diseases? A research group aims to answer this question with artificial intelligence (AI). Their goal is to facilitate the time-consuming analysis of bone marrow cells under the microscope. The researchers developed the largest open-source database on microscopic images of bone marrow cells to date. They use it as the basis for an AI model with high potential for routine diagnostics.
COVID-19 saliva testing kits that include a novel preservative can also be used measure microscopic organisms in the mouth, a new study has found. This enables study of the relationship between mouth and lung microbes and the SARS-CoV-2 virus that may allow for the development of new treatments.
