Currently, 90% of the hydrocarbon resources of the entire continental shelf of Russia are concentrated in the Arctic, including 70% on the shelf of the Barents and Kara Seas. Scientists understand that the shelf is a promising future, and the necessary technological basis for its future development should already be created.
Researchers from the group of Jeroen Bakkers at the Hubrecht Institute (KNAW) have found that the muscle cells in the heart of zebrafish change their metabolism, the way in which they generate energy, during heart regeneration. Contrary to the human heart, the zebrafish heart can regenerate after injury.
Ribonucleic acids (RNA) ensure that the blueprint in the cell nucleus is translated into vital proteins and that cell functions are regulated. However, little is known about the structure and function of particularly long RNAs, which consist of hundreds or thousands of building blocks. Chemists at the University of Bonn have now developed a new method for this purpose: They mark the complex molecules with tiny "flags" and measure the distances between them with a "molecular ruler".
Matching behavior with the way you feel - in other words, not faking it - is more productive at work and leads to other benefits, according to a new study co-authored by Chris Rosen, management professor in the Sam M. Walton College of Business at the University of Arkansas.
Rosen helped design and write a study led by Allison Gabriel, associate professor of management and organizations at the University of Arizona. They published their findings in the Journal of Applied Psychology.
URBANA, Ill. - Urban areas face increasing problems with stormwater management. Impervious surfaces on roads and buildings cause flooding, which impacts the water quality of streams, rivers and lakes. Green infrastructure, including features such as rain barrels, green roofs, rain gardens, and on-site water treatment, can provide affordable and environmentally sound ways to manage precipitation.
Over the course of 2017, positive trends in insurance coverage and healthcare access from the Affordable Care Act reversed, particularly for low-income residents of states that did not expand Medicaid.
A new Boston University School of Public Health (BUSPH) study finds that two million more Americans avoided health care because of inability to pay, and/or did not have health insurance, at the end of 2017 compared to the end of 2016.
Becoming a fossil is the ultimate game of chance.
From the manner of death, to the place where the corpse is buried, to the transformational events that follow, it's a rare occurrence for a specimen to hit a combo that will get it into the fossil record. And only the luckiest of fossils become part of a scientific collection you would see in a museum.
DURHAM, N.H.-- Scientists at the University of New Hampshire have unlocked one of the mysteries of how particles from flares on the sun accumulate at early stages in the energization of hazardous radiation that is harmful to astronauts, satellites and electronic equipment in space. Using data obtained by NASA's Parker Solar Probe (PSP), researchers observed one of the largest events so far during the mission.
New findings from a Dartmouth-led study, published in the February issue of Health Affairs, show that despite effort and attention on the part of some healthcare providers to better address their patients' social needs--such as transportation, housing, and food--little progress is being made to integrate social services with medical care.
HOUSTON - (Feb. 3, 2020) - New simulations by Rice University scientists tell a tale of two taus and how they relate to neurological disease.
Their work suggests tau proteins take either of two paths to form aggregates suspected of promoting, and perhaps causing, Alzheimer's and Pick's (aka frontotemporal dementia) diseases. Precisely why remains a mystery, but figuring it out offers the possibility of controlling their fates.
Blood banks have long known about high-quality donors - individuals whose red blood cells stay viable for longer in storage and in the recipient's body.
Now a new device developed at UBC is showing promise as a method to identify these "super donors", potentially helping more than 4.5 million patients who need blood transfusions every year in Canada and the United States.
Smart technology keeps getting smaller. There are smartphones, smartwatches and now, smart rings, devices that allow someone to use simple finger gestures to control other technology.
Engineering researchers have developed a device the size of a wristwatch that can monitor an individual's body chemistry to help improve athletic performance and identify potential health problems. The device can be used for everything from detecting dehydration to tracking athletic recovery, with applications ranging from military training to competitive sports.
A UCLA-led study has found that levels of six proteins in the blood can be used to gauge a person's risk for cerebral small vessel disease, or CSVD, a brain disease that affects an estimated 11 million older adults in the U.S. CSVD can lead to dementia and stroke, but currently it can only be diagnosed with an MRI scan of the brain.
SAN ANTONIO -- Feb. 3, 2020 -- Using data from NASA's Parker Solar Probe (PSP), a team led by Southwest Research Institute identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. PSP is venturing closer to the Sun than any previous probe, carrying hardware SwRI helped develop. Scientists are probing the enigmatic features of the Sun to answer many questions, including how to protect space travelers and technology from the radiation associated with solar events.
