Boston, MA -- Despite the limited supply of organs available for patients on waitlists for transplantation, organs from older, deceased donors are frequently discarded or not utilized. Available older organs have the potential to close the gap between demand and supply that is responsible for the very long wait-times that lead to many patients not surviving the time it takes for an organ to become available. Older organs can also often provoke a stronger immune response and may put patients at greater risk of adverse outcomes and transplant rejection.
Radiation variations over the Tibetan Plateau (TP) are crucial for global climate and regional ecological environment. Previous radiation studies over the TP were widely based on ground and satellite measurements of the radiation budget at the surface and at the top of the atmosphere.
In situ vertical radiation measurements from the surface up to the upper troposphere and lower stratosphere (UTLS), about 10~22 km in altitude, are rare over the TP or even over a large territory of China.
Engineers at Australia's Monash University have developed world-first technology that can help industry identify and export high quality graphene cheaper, faster and more accurately than current methods.
Published today in international journal Advanced Science, researchers used the data set of an optical microscope to develop a machine-learning algorithm that can characterise graphene properties and quality, without bias, within 14 minutes.
Temperatures in the Arctic Ocean between Canada, Russia and Europe are warming faster than researchers' climate models have been able to predict.
Over the past 40 years, temperatures have risen by one degree every decade, and even more so over the Barents Sea and around Norway's Svalbard archipelago, where they have increased by 1.5 degrees per decade throughout the period.
This is the conclusion of a new study published in Nature Climate Change.
A kind of domino effect -- a convergence of rising temperatures and changing precipitation rates occurred across the planet during the last ice age, stretching from 120,000-11,700 years ago.
According to a study published 21'st of august 2020 in the journal Science, climate changes in several areas of the world affected each other.
Researchers from the Faculty of Physics and Engineering managed to achieve simultaneous power transfer at various frequencies with the help of a metasurface. It will allow us to simultaneously charge devices from different manufacturers with different power transfer standards. The paper was published in Applied Physics Letters.
Cancer therapies sometimes involve drugs that mediate the breakdown of specific intracellular proteins that participate in cancer formation and proliferation. Proteolysis-targeting chimeras or PROTACs are a promising type of protein-degrader molecules, but their effectiveness has been challenged by their limited ability to accumulate inside cells.
Typhoon Bavi is a large storm moving through the Yellow Sea. A NASA camera captured an image of the Northwestern Pacific Ocean that showed Bavi headed north.
NASA's Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope aboard NOAA's DSCOVR satellite in orbit 1 million miles from Earth, captured a full disk image of the Northwestern Pacific Ocean side of the globe. Typhoon Bavi was moving through the Yellow Sea on Aug. 25, 2020 when the image of it was captured.
Antimony sulfide, or stibnite (Sb2S3), has been investigated intensively in recent years as a promising material for nontoxic, environmentally friendly solar cells. It is now possible to fabricate thin photovoltaic films from an ink containing nanoparticles of stibnite, and to nanopattern those films for 2D and 3D structures of pretty much any shape. Such simple, cost-effective production methods fulfill prerequisites for reliable, widespread use.
Army researchers discovered a way to further enhance quantum systems to provide Soldiers with more reliable and secure capabilities on the battlefield.
Specifically, this research informs how future quantum networks will be designed to deal with the effects of noise and decoherence, or the loss of information from a quantum system in the environment.
BOSTON - (August 26, 2020) - Obesity is the main cause of type 2 diabetes and related chronic illnesses that together will kill more people around the globe this year than the Covid-19 coronavirus. Scientists at Joslin Diabetes Center have delivered a proof of concept for a novel cell-based therapy against this dangerous condition.
UC Davis researchers hope other states can use their study efforts as a basis for improving firearm injury prevention.
“We found that the number of nonfatal firearm injuries in California decreased over an 11-year period, primarily due to a drop in firearm assaults,” said Sarabeth Spitzer, lead author and a UC Davis research intern at the time of the study. “However, the lethality of those and other firearm injuries did not go down. In fact, it went up.”
DURHAM, N.C. - Biomedical engineers at Duke University have shown that the efficacy of a two-pronged type 2 diabetes treatment increases when the drugs are linked by a heat-sensitive tether rather than simply concurrently administered. The combination molecule is formed by an elastin-like polypeptide (ELP) linker that forms a gel-like depot when injected under the skin, which slowly dissolves and releases the active drug over time.
CORVALLIS, Ore. - In the American Southwest, native desert bighorn sheep populations found in landscapes with minimal human disturbance, including several national parks, are less likely to be vulnerable to climate change, according to a new study led by Oregon State University.
Up to 60 percent of patients with multiple sclerosis (MS) report that fatigue is the disease's most debilitating symptom. And yet, fatigue remains one of MS's mysteries -- despite its prevalence and significance, the root cause of the symptom remains unclear. In a study published in Neurology Neuroimmunology & Neuroinflammation, investigators from Brigham and Women's Hospital used positron emission technology (PET) imaging to look for brain's immune cells that may become erroneously activated in MS, leading to fatigue.
