A researcher examined the role of cholesterol in both Alzheimer's disease and Type 2 diabetes to identify a small molecule that may help regulate cholesterol levels in the brain, making it a potential new therapeutic target for Alzheimer's disease.

Narcissism is driven by insecurity, and not an inflated sense of self, finds a new study, which may also explain what motivates the self-focused nature of social media activity.

Materials that contain special polymer molecules may someday be able to warn us when they are about to fail, researchers said. Engineers have improved their previously developed force-sensitive molecules, called mechanophores, to produce reversible, rapid and vibrant color change when a force is applied.

Expectant women are more likely to give birth early if they have high blood levels of a chemical used in flame retardants compared with those who have limited exposure, a new study finds.

Rabbits and other hopping animals require a functional RORB gene to move around by jumping, according to a new study.

Bald eagles, as well as other wildlife, have been succumbing to a mysterious neurodegenerative disease in the southern United States since the 1990s. New research identifies the cause of these deaths: a toxin produced by cyanobacteria that grow on invasive aquatic plants. The problem is potentially exacerbated by herbicides used to control those plants.

The ocean's mammals are at a crucial crossroads - with some at risk of extinction and others showing signs of recovery, researchers say.

A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years. The results provide new insights into the inner workings of the global carbon cycle and, in particular, the processes by which carbon is removed from the environment through the deposition of...

Since 1990, California has used its authority under the federal Clean Air Act to enact more aggressive rules on emissions from diesel vehicles and engines compared to the rest of the U.S. Extending these standards to the rest of the U.S. could dramatically improve the nation's air quality and health, particularly in lower income communities of color, finds a new analysis.

Researchers have found the new mRNA COVID-19 vaccines to be highly effective in producing antibodies against the SARS-CoV-2 virus in pregnant and lactating women. They also demonstrated the vaccines confer protective immunity to newborns through breastmilk and the placenta.

Pregnant women who consumed the caffeine equivalent of as little as half a cup of coffee a day on average had slightly smaller babies than pregnant women who did not consume caffeinated beverages, according to a new study.

About two decades after first devising a new kind of vaccine, researchers are unlocking why it stops and ultimately clears the monkey form of HIV in about half of nonhuman primates - and why it's a promising candidate to stop HIV in people. Recent scientific papers describe how unusual biological mechanisms that make the cytomegalovirus vaccine platform work.

The claim that old-growth forests play a significant role in climate mitigation, based upon the argument that even the oldest forests keep sucking CO2 out of the atmosphere, is being refuted. Researchers document that this argument is based upon incorrectly analyzed data and that the climate mitigation effect of old and unmanaged forests has been greatly overestimated. Nevertheless, they reassert...

Researchers have discovered specific regions within the DNA of neurons that accumulate a certain type of damage (called single-strand breaks or SSBs). This accumulation of SSBs appears to be unique to neurons, and it challenges what is generally understood about the cause of DNA damage and its potential implications in neurodegenerative diseases.

Inspired by the mastery of artificial intelligence (AI) over games like Go and Super Mario, scientists have trained an AI agent - an autonomous computational program that observes and acts - how to conduct research experiments at superhuman levels by using the same approach.

A chance sighting of an ultra-rare moth kicked off a hunt for the insects across Hawaii, resulting in the rediscovery of one of the archipelago's oldest living lineages of native animals and the description of more than a dozen new moth species to science.

Scientists have taken the connection between wisdom, loneliness and biology one step further, reporting that wisdom and loneliness appear to influence -- and/or be influenced by -- microbial diversity of the gut.

Researchers have developed a mass spectrometry-based technique capable of measuring samples containing thousands of proteins within just a few minutes. It is faster and cheaper than a conventional blood count. To demonstrate the technique's potential, the researchers used blood plasma collected from COVID-19 patients. Using the new technology, they identified eleven previously unknown proteins...

Researchers have uncovered an innovative way to tap into the over-capacity of 5G networks, turning them into 'a wireless power grid' for powering Internet of Things (IoT) devices. The breakthrough leverages a Rotman lens-based rectifying antenna capable of millimeter-wave harvesting at 28 GHz. The innovation could help eliminate the world's reliance on batteries for charging devices by providing...

Researchers found that mice lacking the circadian clock gene called Rev-erb in the brain show characteristics similar to those of human dawn phenomenon in type 2 diabetes.

Millions of years ago, aphid-like insects called whiteflies incorporated a portion of DNA from plants into their genome. A research team reveals that whiteflies use this stolen gene to degrade common toxins plants use to defend themselves against insects, allowing the whitefly to feed on the plants safely.

Researchers have investigated how the X and Y chromosomes evolve and adapt to each other within a population. The results show that breaking up coevolved sets of sex chromosomes could lead to lower survival rates among the offspring - something that could be of importance in species conservation, for example.

A new study has shown substantial benefit to combining monoclonal antibodies and the antiviral remdesivir against advanced Marburg virus.

Early screening can mean the difference between life and death in a cancer and disease diagnosis. That's why researchers are working to develop a new screening technique that's more than 300 times as effective at detecting a biomarker for diseases like cancer than current methods. The technique uses nanoparticles to increase the sensitivity of ELISA.
