Lakes on Greenland Ice Sheet can drain huge amounts of water, even in winter

Using satellite data to 'see in the dark', researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter, a finding with implications for the speed at which the world's second-largest ice sheet flows to the ocean.

Increased rates of organ damage after discharge from hospital with COVID-19

People discharged from hospital after COVID-19 appear to have increased rates of organ damage ("multiorgan dysfunction") compared with similar individuals in the general population, finds a study published by The BMJ today.

Adherence to UK's test, trace, and isolate system is low

Levels of adherence to the UK's test, trace, and isolate system and understanding of the main symptoms of COVID-19 are low, particularly among men, younger age groups, people with a dependent child in the home, key workers, and those experiencing greater financial hardship, finds an analysis of online survey data published by The BMJ today.

US, China consulted on safety as their crafts headed to Mars

Japan's Hitachi acquires GlobalLogic for $9.6 billion

Hitachi Ltd. is buying U.S. digital engineering services company GlobalLogic Inc. for $9.6 billion, the Japanese industrial, electronic and construction conglomerate said Wednesday.

Researchers urge a closer examination of sunlight's efficacy in inactivating the SARS-CoV-2 virus

A year ago scientists everywhere were scrambling to get their minds around the SARS-CoV-2, a novel coronavirus that caused the pandemic from which we are only now beginning to emerge. The world clung to every new development, every bit of science that could provide clues to managing life in the presence of this mysterious killer.

COVID-19-associated seizures may be common, linked to higher risk of death

COVID-19 can have damaging effects on multiple organs in the body, including the brain. A new study led by investigators at Massachusetts General Hospital (MGH) and Beth Israel Deaconess Medical Center (BIDMC) indicates that some hospitalized patients with COVID-19 experience non-convulsive seizures, which may put them at a higher risk of dying. The findings are published in the Annals of Neurology.

Architecture of Eolian successions under icehouse and greenhouse conditions

Anthropogenic climate change is one of the foremost scientific and societal challenges. In part, our response to this global challenge requires an enhanced understanding of how the Earth's surface responds to episodes of climatic heating and cooling. As historical records extend back only a few hundred years, we must look back into the ancient rock record to see how the surface of the Earth has responded to shifts between icehouse (presence of ice at the Earth's poles) and greenhouse (no substantial ice at Earth's poles) climates in the past.

Heart attacks in young adults more deadly in those with systemic inflammatory disease

Heart attacks in young adults are twice as likely to be fatal in those with inflammatory conditions like psoriasis, lupus or rheumatoid arthritis. That's the finding of a study published today in the European Journal of Preventive Cardiology.

Lab-made hexagonal diamonds stiffer than natural diamonds

Nature's strongest material now has some stiff competition. For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than the common cubic diamonds found in nature and often used in jewelry.

Floating gardens as a way to keep farming despite climate change

Bangladesh's floating gardens, built to grow food during flood seasons, could offer a sustainable solution for parts of the world prone to flooding because of climate change, a new study has found.

Sounds like home: Murrelets choose breeding locations by eavesdropping on other murrelets

Oregon State University researchers broadcast marbled murrelet calls in mature forests and found that the threatened seabirds' choice of breeding locations is strongly influenced by whether they hear other murrelets in the area.

Study investigates non-verbal signs of resistance

A new study examining how people with severe and profound intellectual disabilities resist activities while in care recommends that institutions improve training to help carers better understand non-verbal cues, as well as offer greater flexibility to allow individual preferences to take priority over institutional schedules.

Preventive treatment reduces diabetic retinopathy complications

Early treatment with anti-VEGF injections slowed diabetic retinopathy in a clinical study from the DRCR Retina Network (DRCR.net). However, two years into the four-year study its effect on vision was similar to standard treatment, which usually begins at the onset of late disease. The intermediate findings published today in the JAMA Ophthalmology. The study was supported by the National Eye Institute (NEI), a part of the National Institutes of Health.

Decellularized spinach serves as an edible platform for laboratory-grown meat

Spinach, a cost-efficient and environmentally friendly scaffold, provided an edible platform upon which a team of researchers led by a Boston College engineer has grown meat cells, an advance that may accelerate the development of cultured meat, according to a new report in the advance online edition of the journal Food BioScience.

'Mop up' malaria vaccine advances to trials in people

University of Florida researcher Rhoel Dinglasan, Ph.D., was awarded $6 million today by the Global Health Innovative Technology Fund to test a new malaria vaccine in people. The process leading to a phase 1 clinical trial begins this April.

Dementia and COVID: What families and physicians should know

Early in the pandemic, neurologists expressed concern that COVID-19 patients with dementia may be at higher risk for complications and mortality.

Scientists discover new genetic disease that delays brain development in children

Scientists have discovered a new genetic disease, which causes some children's brains to develop abnormally, resulting in delayed intellectual development and often early onset cataracts.

Human hiking trails custom built for sauntering grizzlies

In the run up to hibernation, grizzly bears go on a colossal binge, consuming as many calories as possible to get them through the long winter. Yet, little was known about how much energy the massive mammals use as they shamble around their rugged territories. "Moving across the landscape in search of food can be a huge energetic expense for some animals," Carnahan says. Fortunately, the Washington State University Bear Research, Education and Conservation Center (WSU BREC), where Carnahan is based, is home to 11 bears, including four that formerly lived in Yellowstone National Park, so he and Charles Robbins (also at WSU BREC) decided to measure the animals' metabolic rates as they sauntered on the flat, and up and down gradients to find out how much energy they use on a daily basis. The team publishes their discovery that grizzly bears prefer to walk on shallow paths to save energy in Journal of Experimental Biology, explaining why the animals often appear on human hiking trails.

New research shows risk of COVID-19 from aerosols to healthcare workers

New research published in Anaesthesia (a journal of the Association of Anaesthetists) challenges the guidance that special aerosol precautions are only needed when using oxygen therapies for COVID-19 patients, and raises concerns about safety of staff and patients on hospital wards, if they are not protected from infectious aerosols.

Experimental treatment offers hope of fertility for early menopausal women

Menopause typically signals the end of a woman's ability to become pregnant. However, in a small new study, a novel approach of administering platelet-rich plasma and gonadotropins near the ovarian follicles is showing promise in restoring ovarian function. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
