Novel insights of how prostate cancer causes secondary tumors

An increased awareness on a molecular level of what mechanisms prostate cancer cells use to become mobile and start spreading may in the long run provide new opportunities for treatment of aggressive prostate cancer. This according to a new study by researchers at Umeå University, Sweden, in collaboration with researchers in Uppsala and Tokyo.

Operation Outbreak simulation teaches students how pandemics spread

In 2015, a team of specialists in modeling disease outbreaks got together with educators to create Operation Outbreak, an educational platform and simulation intended to teach high school and college students the fundamentals of responses to pandemics. The program, which is open source and freely available, includes a Bluetooth-based app that carries out contact tracing by recording transmission...

Peculiar planetary system architecture around three Orion stars explained

In our Solar System, the eight planets and many other minor objects orbit in a flat plane around the Sun; but in some distant systems, planets orbit on an incline --sometimes a very steep one. New work published in Science by an international team could explain the architecture of multi-star systems in which planets are separated by wide gaps and do not orbit on the same plane as their host star's...

Quantum leap for speed limit bounds

Nature's speed limits aren't posted on road signs, but Rice University physicists have discovered a new way to deduce them that is better -- infinitely better, in some cases -- than prior methods.

Radiology research funding has increased -- still no association with citation rate

According to ARRS' AJR, almost half of the research articles published in AJR, Radiology, and European Radiology declared funding -- a proportion that has increased from 17% of articles in 1994 and 26.9% published between 2001 and 2010. Most funded articles received support from federal sponsors or nonprofit foundations, whereas only a minority of funded articles were supported by private...

Researchers probe Soldier sleep deprivation effects

New Army-funded study looks at effects of sleep deprivation, which can greatly affect Soldiers on the battlefield.Research conducted at the University of Rochester Medical Center and funded by the Army Research Office, an element of the U.S. Army Combat Capabilities Development Command's Army Research Laboratory, suggests that people who rely on sleeping during daytime hours are at greater risk...

Researchers redesign the face mask to improve comfort and protection

Imagine a reusable face mask that protects wearers and those around them from SARS-CoV-2, is comfortable enough to wear all day, and stays in place without frequent adjustment. Based on decades of experience with filtration and textile materials, Georgia Institute of Technology researchers have designed a new mask intended to do just that -- and are providing the plans so individuals and...

Seeing progress

As we get older, many of our body's processes start slowing down. For instance, a cut on the hand will take longer to heal after middle age than in youth. That said, it still heals.

Start here to make a protein

Researchers at UC Davis and the MRC Laboratory of Molecular Biology in Cambridge, U.K. have solved the the structure of the complex formed when mRNA is being scanned to find the starting point for translating RNA into a protein. The discovery, published Sept. 4, 2020 in Science, provides new understanding of this fundamental process.

Study in half a million adults with overweight or obesity suggests benefit of weight loss on serious health problems

People with obesity who intentionally (not because of illness) lost an average (median) 13% of their initial body weight reduced their relative risk of developing type 2 diabetes by 42%-44%, sleep apnoea by 22%-27%, high blood pressure by 18%-25%, and dyslipidaemia (unusually high levels of cholesterol and other fats in the blood) by 20-22%, according to a study of over 550,000 adults in primary...

Study of siblings finds moderate cannabis use impacts cognitive functioning

A new study led by researchers from the University of Colorado School of Medicine compares adolescent siblings to determine the impact of early and frequent use of marijuana on cognitive function. This study, published in the journal Addiction, contrasts with previous studies by finding that moderate adolescent cannabis use may have adverse effects that cannot be explained by the genetic or...

Study: Vitamin D deficiency may raise risk of getting COVID-19

In a retrospective study of patients tested for COVID-19, researchers at the University of Chicago Medicine found an association between vitamin D deficiency and the likelihood of becoming infected with the coronavirus. The findings were published Sept. 3, 2020 in JAMA Network Open.

Tear gas should be banned, researchers find; here's why

Tear gas should be banned as it is inherently indiscriminate and frequently abused when deployed against peaceful assemblies, in enclosed spaces, in excessive quantities and against vulnerable populations. It cannot distinguish between the young and the elderly, the healthy and the sick, the peaceful and the violent. Its deployment can also cause myriad health harms, including severe injuries and...
