New research finds that the consumption of healthy plant-based foods, including fruits, vegetables, nuts, coffee, and legumes, is associated with a lower risk of developing type 2 diabetes (T2D) in generally healthy people and support their role in diabetes prevention.

What happens below the cellular level when the heart contracts and relaxes has long been unexplored. Thanks to new ultra-high-resolution electron microscopy techniques, scientists can now watch the heart beating -- almost at a molecular level.

Most simulations of our climate's future may be overly sensitive to Arctic ice melt as a cause of abrupt changes in ocean circulation, according to new research.

A group of bat viruses related to SARS-CoV-2 can also infect human cells but uses a different and unknown entryway. While researchers are still honing in on how these viruses infect cells, the findings could help in the development of new vaccines that prevent coronaviruses from causing another pandemic.

A new study finds that liberals and conservatives differ in how they perceive dominance in women, which may influence their likelihood to vote them into political office.

High-income nations are responsible for 74 percent of the global excess in resource extraction over the 1970-2017 period, driven primarily by the United States and the countries of the European Union. This is demonstrated in an international study, which determines national responsibility for ecological breakdown by calculating the extent to which each nation has overshot their fair share of sustainable resource use thresholds.

A combined study of genetics and skeletal remains show that the switch from primarily hunting, gathering and foraging to farming about 12,000 years ago in Europe may have had negative health effects as indicated by shorter than expected heights in the earliest farmers, according to an international team of researchers.

Scientists have developed a tunable graphene-based platform that allows for fine control over the interaction between light and matter in the terahertz (THz) spectrum to reveal rare phenomena known as exceptional points. The work could advance optoelectronic technologies to better generate, control and sense light and potentially communications, according to the researchers. They demonstrated a way to control THz waves, which exist at frequencies between those of microwaves and infrared waves. The feat could contribute to the development of 'beyond-5G' wireless technology for high-speed communication networks.

As a result of the UK leaving the European Union, logistics firms have faced additional friction at UK borders. Consequently, there have been calls for automated digital borders, but few such systems exist. Researchers have now discovered that a blockchain-based platform can improve supply chain efficiency and trust development at our borders.

Researchers have investigated how to prevent knowledge and skills that were learned long ago and are rarely used from getting rusty.

Two DNA defense systems protect the bacterial strains responsible for the ongoing seventh cholera pandemic from potentially harmful genetic material and viruses, scientists have found. Their study also shows that the defense systems may have been key in the evolution and success of these strains.

A team of scientists has discovered how working memory is 'formatted' -- a finding that enhances our understanding of how visual memories are stored.

Researchers have trained a machine learning model to identify people with post-traumatic stress disorder with 80 per cent accuracy by analyzing text data. The model could one day serve as an accessible and inexpensive screening tool to support health professionals in detecting and diagnosing PTSD or other mental health disorders through telehealth platforms.

People may feel less vulnerable and take fewer safety precautions about COVID-19 when they are with, or even just think about, their friends instead of acquaintances or strangers, according to new research.

Researchers have captured images of multiple radionuclides in mice using astronomy technology.
