Rapid-acting antidepressants, including ketamine, scopolamine and psilocybin, have been found to have immediate and lasting positive effects on mood in patients with major depressive disorder but how these effects arise is unknown. New research has exp…

The widely used dry-cleaning and degreasing solvent perc can be converted to useful chemicals by a new clean, safe and inexpensive procedure. The discovery using on-demand UV activation may open the path to upcycling perc and thus contribute to a more …

Soy compounds called isoflavones are among the plant-derived compounds that may significantly reduce the risk of breast cancer recurrence or death, according to a new meta-analysis.

Researchers uncovered a fundamental mechanism that controls the body’s response to limited oxygen and regulates blood vessel disease of the lung.

By exploiting the technology used in Covid-19 vaccines, a team of scientists has created an effective therapy for a rare disease, in a study in mice, demonstrating the technology’s potential therapeutic use in people.

Increases in symptoms of depression are associated with a subsequent increase in bodyweight when measured one month later, new research has found. The study found that the increase was greatest among people with overweight or obesity, but found no link…

An atlas revealing the activity of individual placental cells during childbirth offers insight on what happens at the maternal-fetal interface during term labor, according to a new study.

More than 200 genes linked to depression have been newly identified in a worldwide study.

A new CRISPR interference (CRISPRi) model explores how the pioneer transcription factor FOXA controls human endoderm differentiation during liver development, and how the pioneer transcription factor OCT4 influences the behavior of pluripotent stem cel…

Picrodontids — an extinct family of placental mammals that lived several million years after the extinction of the dinosaurs — are not primates as previously believed.

Novel findings from a preclinical head-to-head comparison show that administering a COVID-19 vaccine as a nasal spray rather than a subcutaneous injection enhances the body’s long-term immune memory, thereby increasing the vaccine’s overall effectivene…

Research reveals that adults with PTSD have a 2% smaller cerebellum than people without the disorder. The finding expands understanding of the cerebellum’s role in the brain beyond balance and movement to include emotion and cognition and also suggests…

The North Arabian Desert oases were inhabited by sedentary populations in the 4th and 3rd millennia BCE. A fortification enclosing the Khaybar Oasis — one of the longest known going back to this period — was just revealed by a team of scientists. Thi…

New research from the Netherlands Institute for Neuroscience shows that chandelier cells, a specific type of brain cell, become active during unexpected situations. ‘Researchers have been wondering about the functionality of these cells for a long time’.

New research has revealed how light can be used to destroy infectious coronavirus particles that contaminate surfaces. Scientists are interested in how environments, such as surgeries, can be thoroughly disinfected from viruses such as SARS-CoV-2 that …

Exposure therapy for a specific fear can also help reduce other fears. This is the conclusion reached by psychologists who studied 50 people with a fear of spiders and heights. Although they only treated the fear of spiders, the fear of heights was lik…
