Two recent papers from Hungarian researchers highlight the so far underrated relevance of pet dog biobanking in molecular research and introduce their initiative to make pioneering steps in this field. The Hungarian Canine Brain and Tissue Bank (CBTB) was established by the research team of the Senior Family Dog Project in 2017, following the examples of human tissue banks. In a recent paper, the team reports findings, which would not have been possible without the CBTB, and may augment further progress in dog aging and biomarker research.
Clinicians and scientists have long observed that cells in overstressed hearts have high levels of the simple sugar O-GlcNAc modifying thousands of proteins within cells. Now, researchers at Johns Hopkins Medicine have found evidence in mouse experiments that these excess sugars could well be a cause, not merely a consequence or marker of heart failure.
A new discovery led by Princeton University could upend our understanding of how electrons behave under extreme conditions in quantum materials. The finding provides experimental evidence that this familiar building block of matter behaves as if it is made of two particles: one particle that gives the electron its negative charge and another that supplies its magnet-like property, known as spin.
The chemical compound glyphosate, the world's most widely used herbicide, can weaken the immune systems of insects, suggests a study from researchers at the Johns Hopkins Bloomberg School of Public Health. Glyphosate is the active ingredient in Round Up™, a popular U.S. brand of weed killer products.
CORVALLIS, Ore. - Free from human disturbance for a century, an inland island in Central America has nevertheless lost more than 25% of its native bird species since its creation as part of the Panama Canal's construction, and scientists say the losses continue.
The Barro Colorado Island extirpations show how forest fragmentation can reduce biodiversity when patches of remnant habitat lack connectivity, according to a study by researchers at Oregon State University.
Leesburg, VA, May 13, 2021--According to an open-access Editor's Choice article in ARRS' American Journal of Roentgenology (AJR), CT features may help identify which patients with stage IA non-small cell lung cancer are optimal candidates for sublobar resection, rather than more extensive surgery.
When a piece of conducting material is heated up at one of its ends, a voltage difference can build up across the sample, which in turn can be converted into a current. This is the so-called Seebeck effect, the cornerstone of thermoelectric effects. In particular, the effect provides a route to creating work out of a temperature difference. Such thermoelectric engines do not have any movable part and are therefore convenient power sources in various applications, including propelling NASA's Mars rover Perseverance.
If you're a fan of spy movies, you've probably come across scenes where the intelligence agents try to identify or detect a perpetrator using some sophisticated image enhancement technology on surveillance camera images. While the idea behind surveillance cameras and object detection is the same in real life, unlike in movies, there is often a trade-off between the camera's field-of-view and its resolution.
A new study from North Carolina State University finds that greenhouse gas (GHG) emissions from standing dead trees in coastal wetland forests - colloquially called "tree farts" - need to be accounted for when assessing the environmental impact of so-called "ghost forests."
In 2020, stores sold out of garden seed, coops and rabbit cages. Now, we have an idea how much protein people can grow in their backyards.
A new, noninvasive method for measuring brain blood flow with light has been developed by biomedical engineers and neurologists at the University of California, Davis, and used to detect brain activation. The new method, functional interferometric diffusing wave spectroscopy, or fiDWS, promises to be cheaper than existing technology and could be used for assessing brain injuries, or in neuroscience research. The work is published May 12 in Science Advances.
MISSOULA - Only an anthropologist would treasure millennia-old human feces found in dry caves.
Just ask Dr. Meradeth Snow, a University of Montana researcher and co-chair of UM's Department of Anthropology. She is part of an international team, led by the Harvard Medical School-affiliated Joslin Diabetes Center, that used human "paleofeces" to discover that ancient people had far different microorganisms living in their guts than we do in modern times.
Wild orangutans are known for their ability to survive food shortages, but scientists have made a surprising finding that highlights the need to protect the habitat of these critically endangered primates, which face rapid habitat destruction and threats linked to climate change.
All modern life is composed of cells, from single-celled bacteria to more complex organisms such as humans, which may contain billions or even trillions of cells, but how life came to be cellular remains uncertain. New research led by specially appointed assistant professor Tony Z.
Scientists are exploring a number of ways for people with disabilities to communicate with their thoughts. The newest and fastest turns back to a vintage means for expressing oneself: handwriting.
For the first time, researchers have deciphered the brain activity associated with trying to write letters by hand. Working with a participant with paralysis who has sensors implanted in his brain, the team used an algorithm to identify letters as he attempted to write them. Then, the system displayed the text on a screen - in real time.
