In the past, there has been much excitement over research that purported to show a link between changes in a woman's cycle and how attracted she was to men behaving in different ways. However, research at the University of Göttingen using the largest sample size to date questions these results. The new research showed that shifts in women's cycles did not affect their preferences for men's behaviour.
Astronauts in space live on processed, pre-packaged space rations such as fruits, nuts, chocolate, shrimp cocktails, peanut butter, chicken, and beef to name a few. These have often been sterilized by heating, freeze drying, or irradiation to make them last and key a challenge for the US Space Agency NASA has been to figure out how to grow safe, fresh food onboard.
Philadelphia, March 6, 2020 - Parents may let their children consume more sugar from their breakfast cereal than intended due to insufficient industry nutritional guidelines.
NEW YORK, March 6, 2020 -- Researchers at the Advanced Science Research Center at The Graduate Center, CUNY (CUNY ASRC) and Northwestern University have created a 4D printer capable of constructing patterned surfaces that recreate the complexity of cell surfaces. The technology, detailed in a newly published paper in Nature Communications (DOI: 10.1038/s41467-020-14990-x), allows scientists to combine organic chemistry, surface science, and nanolithography to construct precisely designed nanopatterned surfaces that are decorated with delicate organic or biological molecules.
The Imperial College London and UCL researchers say their proof-of-concept study, published today in npj Digital Medicine, paves the way for the development of high-fidelity clinical imaging of the human brain that could be superior to existing technology.
A groundbreaking study will enable scientists to better predict future warming of the world's lakes due to climate change, and the potential threat to cold-water species such as salmon and trout.
Pioneering research led by the UK Centre for Ecology & Hydrology (UKCEH) has devised the first system that classifies lakes globally, placing each of them in one of nine 'thermal regions' (see map).
Older parents are less flexible when it comes to raising their offspring, according to a new study of beetles.
University of Exeter scientists studied a species of burying beetle which raises its young on carcasses of small animals such as mice or birds.
They found that younger females adapted the number and total weight of offspring, and the effort they put into caring for them, based on the size of the carcass (smaller carcasses mean less food is available).
Caltech and JPL have been successful partners in space exploration since the mid-1930s. In their tradition of intermixing in unique ways fundamental science, technology and engineering they develop a collaborative multi-disciplinary cross-agency research program to advance and accelerate scalable hybrid quantum networking and communications technologies.
Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around 40% of its usual brightness. The activity fueled popular speculation that the red supergiant would soon explode as a massive supernova.
But astronomers have more benign theories to explain the star's dimming behavior. And scientists at the University of Washington and Lowell Observatory believe they have support for one of them: Betelgeuse isn't dimming because it's about to explode -- it's just dusty.
VANCOUVER, Wash. - Research at Washington State University has linked chronic depression with increased health problems for moms and children in poor rural communities, revealing the need for better treatment based on teamwork and trust.
Using data from the ongoing, multi-state Rural Families Speak project, a team led by Yoshie Sano, associate professor in WSU's Department of Human Development, examined the experiences of 23 mothers with clinical depression across three years.
Okazaki, Japan - Although a number of techniques are able to track changes in pH in the brain, precise measurements have not previously been possible. Now, however, researchers in Japan have developed a novel method for examining brain pH that may lead to new information about the role of pH in brain signaling.
New research has found that music therapy sessions have a positive effect on the neurorehabilitation of acute stroke patients, as well as their mood.
The study - the first large-scale investigation into the feasibility of delivering these exercises - was led by Dr Alex Street, of Anglia Ruskin University (ARU), and was carried out on a 26-bed stroke and rehabilitation unit at Addenbrooke's hospital in Cambridge.
Baltimore, MD--Antibiotics can make easy work of infections. But how do they affect the complex ecosystems of friendly bacteria that make up our microbiome?
"When a doctor prescribes antibiotics, it sets up a multi-faceted experiment in your gastrointestinal system," explains Carnegie's Will Ludington "What can this teach us about the molecular principles of species interactions in nature?"
Bethesda, Maryland (March 5, 2020) -- The world is bracing for the impact of the novel coronavirus, COVID-19, which has now spread to over 30 countries, infecting more than 80,000 people with over 2,600 deaths globally. A better understanding of how this virus is transmitted is key to preventing its spread.
In two new papers published online in Gastroenterology, investigators from China describe the impact of coronavirus on the digestive tract. Key findings:
Leesburg, VA, March 5, 2020--An article by radiologists from Wuhan, China--published open-access and ahead-of-print in the American Journal of Roentgenology (AJR)--concluded that chest CT had a low rate of misdiagnosis of COVID-19 (3.9%, 2/51) and could help standardize imaging features and rules of transformation for rapid diagnosis; however, CT remains limited for the identification of specific viruses and distinguishing between viruses.
