A new study identifies key patterns and factors influencing insect pest establishment and detection across the U.S. and suggests public surveillance awareness and involvement is a critical component of efforts to protect agriculture and our ecosystems from harmful pests. The findings can be used to improve strategies for early detection and response to new insect

When doctors sit at hospitalized patients' bedsides, it can have a more positive impact than if they stand, a review of data suggests -- but a new study seeks to find out for sure. Doctors and others who take care of hospitalized patients may want to sit down for this piece of news. A new

Targeted physical training can improve the quality of life of patients with metastatic breast cancer and alleviate fatigue. This is shown by an international randomized multicenter study. In the course of the training program, which included two sessions per week over nine months, disease- and therapy-related symptoms were markedly reduced, which was associated with a

A new study brings researchers closer to better understanding the pathology of the fatty liver disease MASH, which stands for metabolic dysfunction-associated steatohepatitis. MASH is a consequence of poor diet and obesity and results in severe damage to the liver. In MASH, the liver becomes filled with active and rapidly multiplying T cells, which are

Mosquito-borne viral infections once confined to tropical regions are spreading. Dengue virus infects up to 400 million people worldwide each year according to World Health Organization estimates, and no available treatments exist for this disease. Now, research uncovered surprising strategies for how dengue and hundreds of other viruses replicate in their hosts, with the potential

Over the last century, a once-deadly mosquito-borne virus has evolved so that it no longer sickens humans. New research shows that changes in the virus's ability to target human cells paralleled the decline in illness and death. The findings offer important lessons in virology that may help guide better preparedness for future outbreaks of other

New research finds a tiny freshwater parasite known to cause health problems in humans defends its colonies with a class of soldiers that cannot reproduce. The discovery vaults this species of parasitic flatworm into the ranks of complex animal societies such as ants, bees and termites, which also have distinct classes of workers and soldiers

For patients with Afib, using a wearable device can lead to higher rates of anxiety about their Afib symptoms and treatment, doctor visits, and use of informal healthcare resources, according to a new study. Using a wearable device, such as a smart watch, to track health data and symptoms, is supposed to help people monitor

Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. The study showed that traffic-related UFPs impair mitochondrial functions in primary human olfactory mucosa cells by hampering oxidative phosphorylation and redox balance. Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder

The COVID-19 pandemic significantly widened existing economic and health disparities between wealthy and low-income countries and slowed progress toward health-related Sustainable Development Goals (SDGs), according to a new study.

People who speak a language that has multiple words for different shades of colour perceive the shades more quickly. Bees have a phenomenal ability to perceive different shades of colour, and their eyes are able to see ultraviolet light. This helps them find flowers that produce nectar. Human beings are also influenced by colours and

Tweaking the numbers of receptors in a key brain area changes the daily rhythms of rest and wake in mice. In humans and other animals, signals from a central circadian clock in the brain generate the seasonal and daily rhythms of life. They help the body to prepare for expected changes in the environment and
