High doses of a widely used drug used in the hormonal treatment of conditions such as excessive hair growth, early puberty, and prostate cancer, are linked to an increased risk of meningioma – the most common type of benign brain tumour, finds a University of Bristol-led study of over 8 million patients. The study is published in Scientific Reports.
Typically slow growing, meningiomas are benign tumours that are often revealed incidentally by imaging but can cause significant...
University of Delaware (UD) engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical system powered by hydrogen.
It is a significant advance for carbon dioxide capture and could bring more environmentally friendly fuel cells closer to market, writes Karen Roberts of the University of Delaware.
The research team, led by UD professor Yushan Yan, reported its method in Nature Energy today.
Fuel cells work by converting fuel chemical energy directly into electricity. They can be used in...

Mobile phone companies' 5G networks are bringing more speed and innovation to consumers, but there is at least one trade-off: to open up airwaves for 5G, the companies are shutting down older networks that many devices and services still use, reports Jon Healey of the Los Angeles Times.
Those older 3G networks were heralded as a revolutionary advancement in bandwidth and connectivity when they debuted in the United States in 2002. Although 3G (short for third generation)...

Being overweight or obese has long been linked to poor heart health, but could it also impair your thinking?
New research out of Canada suggests it very well might.
Working with thousands of young, middle aged, and older adults, the new study highlights what appears to be fat's direct harm on one's ability to think quickly, with rising body fat levels linked to diminishing mental health returns.
"Our findings are intriguing, because we show that , as it increases, not...
Athletes and visitors heading to the 2022 Winter Olympics in Beijing should leave their phones at home and use temporary ones instead, the FBI has urged.
It comes in a wider warning about how cyber-activities may disrupt the events. Those include ransomware and denial of service attacks, the BBC reports.
But it also cautioned about malware, data theft, and the installation of "tracking tools" on mobile devices.
"The FBI urges all athletes to keep their personal cell phones...
Researchers have explored the cellular changes that occur in human mammary tissue in lactating and non-lactating women, offering insight into the relationship between pregnancy, lactation, and breast cancer, reports the University of Cambridge.
The study was led by researchers from the Wellcome-MRC Cambridge Stem Cell Institute (CSCI) and the Department of Pharmacology at the University of Cambridge.
Breast tissue is dynamic, changing over time during puberty, pregnancy, breastfeeding, and aging. The paper, published today in the journal Nature...

A state-of-the-art asteroid alert system operated by the University of Hawaii Institute for Astronomy (IfA) can scan the entire dark sky every 24 hours for dangerous bodies that could hurtle toward Earth.
The NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) has expanded its reach to the southern hemisphere, from two existing northern hemisphere telescopes on Hawaiian volcanoes Haleakalā and Maunaloa. Construction is complete, and operations are under way on telescopes in...
China Unicom has become the latest Chinese telecommunications giant to be banned from the U.S. over "significant" national security and espionage concerns, the BBC reports.
The Federal Communications Commission (FCC) said it had voted unanimously to revoke authorization for the company's American unit to operate in the U.S.
