Researchers are examining neurons and hormones associated with eating too much. This study is another step in understanding the brain circuits involved in eating disorders.

Intermittent fasting can produce clinically significant weight loss as well as improve metabolic health in individuals with obesity, according to a new study.

The structural integrity of the brain's white matter as measured with an advanced MRI technique is lower in cognitively normal people who carry a genetic mutation associated with Alzheimer's disease than it is in non-carriers, according to a new study. Researchers said the findings show the promise of widely available imaging techniques in helping to understand early structural changes in the...

At a time when only one country in the world is on track to reduce greenhouse gas emissions in line with limiting global warming to 1.5ºC, a new study published in Global Change Biology provides a comprehensive reference guide on the potential and feasibility of land-based climate solutions for over 200 countries.

Most people have already experienced first-hand how important a healthy microbiome is when they had to take a broad-spectrum antibiotic. Unfortunately, the drug does not only destroy the pathogens. It also affects the 'good' bacteria in the bowel that otherwise occupy the most important niches and help fend off pathogens. This protective mechanism is called colonization resistance. But which...

A team of researchers from Friedrich-Schiller-University Jena, Universit di Trento and the University of Birmingham has developed a way to "listen" to sounds generated in a fluid of light. In their paper published in the journal Physical Review Letters, the group describes their work and its possible use as a new way to study fluids.

Solar radio spikes are short duration, narrowband radio bursts that are signatures of the acceleration of non-thermal electrons in solar flares. They are observed over a wide range of frequencies from the tens of MHz (Melnik et al. 2014) to the GHz range (Benz et al. 1992) and have some of the shortest durations and narrow bandwidths of any solar radio bursts. The origin of spikes is not fully...

A team of researchers with the Far Western Anthropological Research Group and the Crow Canyon Archaeological Center, has found evidence of the earliest use of wild tobacco in the Americas. In their paper published in the journal Nature Human Behavior, the group describes what they found and where and suggest theories regarding how tobacco might have been used by people thousands of years ago.

China on Tuesday pledged about $290 million to establish a fund to protect biodiversity in developing...

An engineer is reporting fast screening of the surface proteins of exosomes for cancer diagnostics and biomarker discovery.

Researchers have discovered most pet owners have inadequate plans for their pets if a natural disaster strikes -- but disaster response planners may be able to turn this into a positive.

Scientists have developed a chemical compound that interferes with a key feature of many viruses that allows the viruses to invade human cells. The compound, called MM3122, was studied in cells and mice and holds promise as a new way to prevent infection or reduce the severity of COVID-19 if given early in the course of an infection, according to the researchers.

New research finds many women are screened too often for cervical cancer, leading to unnecessary procedures that may carry their own harms, while some women are not getting tested often enough, putting them at higher risk for poor outcomes.

Stress enhances the properties of a promising material for future technologies, with researchers' discovery of a new exotic state of a promising, room-temperature multiferroic material having exciting implications for future technologies using these enhanced properties.

A new study has found whole fat dairy is just as good for kids as low-fat.

Towards solving the heat concentration problem in power semiconductors, researchers have developed a highly efficient boiling immersion cooler using lotus metals. LTS succeeded in increasing the cooling performance from about 200 W/cm2 of the conventional cooler to 530 W/cm2 or more by using the boiling promotion technology using lotus metals. This technology is also considered as a highly...

The immune system protects the body from cancer. To protect healthy body cells from its own immune system, they have developed a protective shield: the protein CD47 is a so called 'don't eat me' signal, which tells the immune cells to stand back. Tumor cells exploit this CD47-based protection strategy for evading the immune system, by increasing presentation of CD47 on their cell surface. A team...

A novel electronic component could be an important key to the era of quantum information technology: Using a tailored manufacturing process, pure germanium is bonded with aluminum in a way that atomically sharp interfaces are created.

Materials consisting of a few atomic layers display properties determined by quantum physics. In a stack of such layers, vibrations of the atoms can be triggered by infrared light. New experimental and theoretical work shows that atomic vibrations within the layers of hexagonal boron nitride, the so-called transverse optical phonons, couple directly to motions of the layers against each other. For...

Spending a long time in space appears to cause brain damage. This is shown by a study of five Russian cosmonauts who had stayed on the International Space Station (ISS).

The intestines of a healthy person contains hundreds of different bacteria that provide efficient protection against infections. However, if the equilibrium of this community, known as the microbiota, is disturbed -- for example, due to antibiotic therapy -- pathogens such as salmonella or multiresistant hospital germs such as Klebsiella pneumoniae can gain the upper hand -- sometimes with severe...

A recent study reveals that inhibiting certain adhesion receptors on the surface of dendritic cells, the main antigen-presenting cells of the immune system, enhances antitumor responses.

Academics have undertaken research that proves Earth Observation satellite imagery can accurately assess the quality and quantity of some habitat types.
