Vegetarians appear to have a healthier biomarker profile than meat-eaters, and this applies to adults of any age and weight, and is also unaffected by smoking and alcohol consumption, according to a new study in over 166,000 UK adults, being presented at this week's European Congress on Obesity (ECO), held online this year.

The first global review of complementary medicines (herbal and dietary supplements) for weight loss in 16 years--combining 121 randomised placebo-controlled trials including nearly 10,000 adults--suggests that their use cannot be justified based on the current evidence. The findings are presented at this year's European Congress on Obesity.

A study presented at this year's European Congress on Obesity (held online, 10-13 May) supports recommendations to avoid pregnancy for 12 months after bariatric (obesity) surgery due to an association with adverse outcomes in pregnancy including an elevated risk of preterm birth.

The finding that breast tumours can evolve to express low HER2 potentially widens the number of patients who can benefit from new investigational agents, typically novel antibody-drug conjugate therapies, that are currently in clinical trials for HER2-low tumours.

Mild Covid-19 infection is very unlikely to cause lasting damage to the structure or function of the heart, according to a study led by UCL (University College London) researchers and funded by the British Heart Foundation (BHF) and Barts Charity.

The use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, does not lead to higher rates of death or severe disease in patients who are hospitalised with COVID-19, according to a new observational study of more than 72,000 people in the UK published in The Lancet Rheumatology journal.

The most comprehensive study of the family tree for legumes, the plant family that includes beans, soybeans, peanuts, and many other economically important crop plants, reveals a history of whole-genome duplications.

Sleep disorders are associated with significantly higher rates of health care utilization including more doctors visits and prescriptions, placing an additional $94.9 billion in costs each year to the U.S. Health care system.

A bacterial protein helps to stop transcription--the process of making RNA copies of DNA to carry out the functions of the cell--by causing the cellular machinery that transcribes the DNA to pause at the appropriate spots in the genome.

Long-running archaeological research, boosted by airborne lidar sensing and machine-learning algorithms, finds that Cambodia's Greater Angkor region was home to 700,000-900,000 people. The new estimate, made possible by a study designed at the University of Oregon, is the first for the entire 3,000-square-kilometer low-density region.

Study examines neighborhood and social network relation to adult binge drinking.

Researchers with the University of Florida have developed a novel method for priming the immune system to fight salmonella infection.

This new form of regulation highlights its potential involvement in fundamental cellular processes that require profound changes in gene expression programmes, such as cell differentiation or reprogramming, as well as tumour transformation and progression.

After the most comprehensive review to date, a panel of leading medical experts conclude that ivermectin should be systematically and globally adopted for the prevention and treatment of COVID-19.

Induced bank filtration is a key and well-established approach to provide drinking water supply to populated areas located along rivers or lakes and with limited access to groundwater resources. It is employed in several countries worldwide, with notable examples in Europe, the United States, and parts of Africa. Contamination of surface waters poses a serious threat to attaining drinking water standards.

Probing the unique biology of human pancreatic cancer cells in a laboratory has yielded unexpected insights of a weakness that can be used against the cells to kill them.

A research team from the Skoltech Center for Design, Manufacturing and Materials (CDMM) studied the effects of processing additives - aluminum hydroxide and zinc stearate - on the polymerization kinetics of thermosets used in pultrusion.

A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping.This is the first time that a measurement has been made of the entropy - or heat loss - generated by a minimal clock tens of nanometers thick and 1.5 millimeters long. Understanding the thermodynamic cost involved in timekeeping is a central step along the way in the development of future technologies, as systems approach the quantum realm.

Neonatal hypothermia -- which occurs when an infant's core body temperature falls below the normal range needed to maintain health -- contributes to approximately one million deaths each year, and countless cases of stunted growth, almost exclusively in low- and middle-income countries. To address this common but preventable condition, researchers from Boston Children's Hospital, engineers at Lawrence Berkeley National Laboratory, and colleagues in Rwanda developed the Dream Warmer, a low cost, reusable non-electric infant warmer to prevent and treat hypothermia.

Training the artificial intelligence models that underpin web search engines, power smart assistants and enable driverless cars, consumes megawatts of energy and generates worrying carbon dioxide emissions. But new ways of training these models are proven to be greener.
