Stone Age black bears didn't just defecate in the woods - they did it in a cave too
2021-04-19
Scientists have sequenced ancient DNA from soil for the first time and the advance will transform what is known about everything from evolution to climate change.
The findings have been described as the 'moon landings' of genomics because researchers will no longer have to rely on finding and testing fossils to determine genetic ancestry, links and discoveries - and it is thanks to Stone Age black bears who defecated in a remote cave in Mexico 16,000 years ago.
A team of scientists from The Lundbeck Foundation GeoGenetics Centre, University of Copenhagen, led by Professor Eske Willerslev, director of the foundation and a Fellow of St John's College, University of Cambridge, recreated ...

Two blood thinners at once: More risk with the same reward
2021-04-19
More blood thinners aren't automatically better, another study confirms.
A new publication in JAMA Internal Medicine focuses on the minimal pros and the concerning cons of combining a daily aspirin with a drug from the newer class of anticoagulants that include apixaban, dabigatran, edoxaban and rivaroxaban.
Patients were taking one of these direct oral anticoagulants known as DOACs to prevent strokes from non-valvular atrial fibrillation or for the treatment of venous thromboembolic disease (deep vein thrombosis or pulmonary embolism). The included patients did not have another reason to take aspirin ...
Gene therapy shows promise in initial trial for patients with childhood blindness
2021-04-19
PHILADELPHIA - A new gene therapy for one of the most common forms of congenital blindness was safe and improved patients' vision, according to initial data from a clinical trial led by researchers at the Scheie Eye Institute in the Perelman School of Medicine at the University of Pennsylvania.
The therapy delivers working copies of GUCY2D to the eyes of patients who have severe vision impairments caused by mutations in the gene. Each of the first three treated patients experienced improvement in some aspects of vision, without serious side effects, according to the new study, published in the journal iScience.
"We found sustained improvements in both day and night vision, even with a relatively low dose of the gene therapy," said study lead author Samuel G. Jacobson, MD, ...

The researchers used tissue samples from 385 brains donated to the Mayo Clinic Brain Bank, which houses more than 9,000 brain tissue specimens for the study of neurodegenerative disorders. The samples were from people who were diagnosed with Alzheimer's disease and lacked co-existing diseases found in ...
Green hydrogen: "Rust" as a photoanode and its limits
2021-04-19
Hydrogen will be needed in large quantities as an energy carrier and raw material in the energy system of the future. To achieve this, however, hydrogen must be produced in a climate-neutral way, for example through so-called photoelectrolysis, by using sunlight to split water into hydrogen and oxygen. As photoelectrodes, semiconducting materials are needed that convert sunlight into electricity and remain stable in water. Metal oxides are among the best candidates for stable and inexpensive photoelectrodes. Some of these metal oxides also have catalytically active surfaces that accelerate the formation of hydrogen at the cathode or oxygen at the anode.
Why is rust not much better?
Research has long focused on haematite (α-Fe2O3), ...
Microglia, Stockholm syndrome and miraculous cures in glioblastoma patients
2021-04-19
MINNEAPOLIS - April 19, 2021 - Despite access to some of the best possible medical care in the world, Senators John McCain and Edward Kennedy both died within 18 months of their diagnosis of glioblastoma, an aggressive form of brain cancer. While this deadly outcome typifies the nature of this disease, some glioblastoma patients see exceptional benefits from chemotherapy and survive beyond expectations. Why this happens has been revealed by researchers at the University of Minnesota in a new study published in the Proceedings of the National Academy of Sciences.
"Deciphering the molecular underpinning of these exceptional ...
Delaying cardiovascular surgeries due to COVID-19 has psychological effects on patients
2021-04-19
In March 2020, when the pandemic hit, everything slowed, including non-essential medical procedures such as elective surgeries, to reduce the spread of the coronavirus.
Six weeks later, Mary Byrnes, Ph.D., an assistant research scientist in the Department of Surgery at Michigan Medicine, began calling University of Michigan Frankel Cardiovascular Center patients whose surgeries had been canceled or delayed. She wanted to hear about their experiences -- what undergoing surgery meant to them, how postponing their operations had affected them, whether the existence of the coronavirus complicated how they felt about their bodies and ...
New factor in the development of psoriasis discovered
2021-04-19
Psoriasis is a common inflammatory skin condition. The underlying genetic factors have not yet been sufficiently researched. The skin inflammation is usually triggered by external factors such as infections or stress. A research team at the Institute of Cancer Research of the Medical University of Vienna has now managed to identify a new factor in signal transmission of the immune system that plays a major role in the development of a psoriatic episode. The scientists have shown that symptoms can be alleviated by inhibiting the "c-Jun" protein in signal transmission.
The common clinical manifestation of psoriasis is a pinkish-grey thickening of the epidermis in distinct foci of infection, ...
SARS-CoV-2 variants from mink evade inhibition by antibodies
2021-04-19
It has been known for about a year that minks can become infected with SARS-CoV-2. The virus had been transmitted from humans to farmed mink and mutated in infected animals. Mutations were acquired in the spike protein, which is crucial for the entry of the virus into host cells and represents the central point of attack for antibodies. These SARS-CoV-2 variants from mink were transmitted back to humans, raising concerns that minks could be a continuing source of infection of humans with SARS-CoV-2 variants with altered biological properties. Researchers at the German Primate Center (DPZ) - Leibniz Institute for Primate Research in Göttingen, Germany, have now shown that an antibody used for COVID-19 ...
Supplement treats schizophrenia in mice, restores healthy "dance" and structure of neurons
2021-04-19
A simple dietary supplement reduces behavioral symptoms in mice with a genetic mutation that causes schizophrenia. After additional experiments, including visualizing the fluorescently stained dancing edge of immature brain cells, researchers concluded that the supplement likely protects proteins that build neurons' cellular skeletons.
The supplement betaine was first isolated from sugar beets and is often associated with sweetness or umami flavor. Healthy levels of betaine come from both external food sources and internal synthesis in the body. Betaine ...
Beetles that pee themselves to death could be tomorrow's pest control
2021-04-19
Up to 25 percent of global food production is lost annually due to insects, primarily beetles. For the past 500 million years, beetles have successfully spread and adapted to life around the globe and now account for one of every five animal species on Earth. Yet as far back as ancient Egypt, these tough little bugs have invaded granaries and vexed us humans by destroying our crops.
As a result, food production and an abundant use of pesticides now go hand in hand. A large share of these pesticides damage biodiversity, the environment and human health. As various pesticides are phased out, new solutions are required to target and eradicate pests without harming humans or beneficial ...
UK waters are home again to the bluefin tuna
2021-04-19
Atlantic bluefin tuna have returned to UK waters and can once again be seen during the summer and autumn months.
Their numbers appear to be increasing, following a long period of absence linked to population decline, according to research led by Cefas and the University of Exeter.
Marine scientists in the UK and Ireland have analysed multiple datasets, spanning a 16-year period, to document the increase in bluefin, which arrive into the waters of the Celtic Seas and off South West England, the Scilly Isles, and North West Ireland to feed in late summer and autumn.
The research is part of the Defra-funded "Thunnus UK" research project. ...
Traumatic brain injuries can increase risk of stroke for up to five years, finds study
2021-04-19
Stroke risk for patients with traumatic brain injuries is at its highest in the four months following injury and remains significant for up to five years post-injury, finds a new systematic review led by a team at the University of Birmingham.
Traumatic brain injury (TBI) is a global health problem affecting over 60 million people a year worldwide. Incidences of TBI are rising due to a range of factors including increased falls in the elderly, military conflict, sports injuries and road traffic accidents. However, advances in critical care and imaging have led to a reduction in TBI-related mortality.
Previous studies have associated TBI with a long-term risk of neurological diseases including dementia, ...
Defects in a specific cell type may cause ulcerative colitis
2021-04-19
There are many variants of "goblet cells" in the intestines and they seem to have different functions, according to a new study from the University of Gothenburg. The study indicates that defects in goblet cells of a particular type may be a factor contributing to ulcerative colitis, an inflammatory bowel disease.
The entire inside of our intestines is covered by a thin layer of mucus that protects the fragile mucous membrane (mucosa) from bacteria and other microorganisms. If the microorganisms repeatedly come into contact with the intestinal mucosa, inflammation and even cell changes may result. These increase the risk of intestinal cancer. In a healthy colon, the mucus layer is up to a millimeter ...

Cotton wool proves effective in separating single-wall carbon nanotubes
2021-04-19
The project was kickstarted in 2017 when a delegation of YTC America (subsidiary of Yazaki Corporation) visited Kazan Federal University. During the talks, YTC suggested that KFU participate in developing effective methods of separating single-wall carbon nanotubes (SWCNTs) into metallic and semiconducting specimens. This was to be done on Tuball tubes produced by OCSiAl, since they are the only ones currently available in industrial quantities.
Carbon nanotubes (CNT) is a family of 1D nanostructures with numerous verified applications, made possible due to their ...
Study shows education is not enough to overcome inequality
2021-04-19
A recent study finds that social inequality persists, regardless of educational achievement - particularly for men.
"Education is not the equalizer that many people think it is," says Anna Manzoni, author of the study and an associate professor of sociology at North Carolina State University.
The study aimed to determine the extent to which a parent's social status gives an advantage to their children. The research used the educational achievements of parents as a proxy for social status, and looked at the earnings of adult children as a proxy for professional success.
