Getting into shape pre-surgery to aid recovery for older patients - study
Older adults about to undergo elective surgery should undertake a sustained programme of targeted exercise beforehand to counteract the muscle-wasting effects of bedrest, new research suggests.

Study sheds new light on how the brain distinguishes speech from noise
For the first time, researchers have provided physiological evidence that a pervasive neuromodulation system - a group of neurons that regulate the functioning of more specialized neurons - strongly influences sound processing in an important auditory region of the brain.

Socioeconomic background linked to survival after having a cardiac arrest in hospital
Hospital in-patients from lower socioeconomic backgrounds are less likely to receive prompt cardiopulmonary resuscitation (CPR) after their hearts stop beating and less likely to survive than patients from higher socioeconomic backgrounds.

Study resolves the position of fleas on the tree of life
A study of more than 1,400 protein-coding genes of fleas has resolved one of the longest standing mysteries in the evolution of insects, reordering their placement in the tree of life and pinpointing who their closest relatives are.

COVID-19: avoiding hospital caused heart disease death rise
Lower rates of hospital attendance for urgent heart problems during the initial phase of the COVID-19 pandemic may have contributed to avoidable deaths in England, finds a new study led by UCL researchers.

Modeling rainfall drop by drop
A high-frequency model developed using data from new high-precision rain gauges gives fresh insight into the dynamics of rain and runoff events.

Protecting against atherosclerosis at the molecular level
Researchers from the University of Tsukuba identified a novel mechanism by which CREB3L3 protects against atherosclerosis.

Performance breakthrough by topological-insulator into a waveguide-resonator system
Topological insulator (TI), a major discovery in condensed matter physics since this century, has now been introduced into waveguide-resonator systems.

How cancers hurt themselves to hurt immune cells more
A study of melanoma cells explains a puzzling response they exhibit to ward off T cell attacks.

Medical oddity reveals unheard-of 'immunity gene' mutations and new way to screen them
Researchers baffled by an infant's rare encephalitis case unusual in children found unheard-of mutations and a new way to examine the 'immunity gene.'

A community-level intervention reduces alcohol-related crashes
New research from the Prevention Research Center of the Pacific Institute for Research and Evaluation shows that a community-level alcohol intervention in California resulted in a 17% reduction in alcohol-involved crashes among drivers aged 15-30.

Goldilocks and the three quantum dots: Just right for peak solar panel performance
Maximizing the efficiency of renewable energy technology is dependent on creating nanoparticles with ideal dimensions and density, new simulations have shown.

New Singapore obstetrics and gynaecology research network established
Singapore's three public hospitals offering maternity services -- KK Women's and Children's Hospital (KKH), Singapore General Hospital (SGH) and the National University Hospital (NUH), have established a collaborative research network.

Scientists solve 'flea mystery'
Researchers from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) and the University of Bristol in the UK solved the 'Flea Mystery.'
