For a long time, ecologists have relied on their senses when it comes to recording animal populations and species diversity. However, modern programmable sound recording devices are now the better option for logging animal vocalisations. Scientists lead by the University of Göttingen have investigated this using studies of birds as an example. The results were published in the journal Ecological Applications.
Blood tests that detect inflammation, known as inflammatory marker tests, are not sensitive enough to rule out serious underlying conditions and GPs should not use them for this purpose, according to researchers from the University of Bristol's Centre for Academic Primary Care, University of Exeter and the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care West (NIHR CLAHRC West).
If you've ever pressed a picture-hanging strip onto the wall only to realize it's slightly off-center, you know the disappointment behind adhesion as we typically experience it: it may be strong, but it's mostly irreversible. While you can un-stick the used strip from the wall, you can't turn its stickiness back on to adjust its placement; you have to start over with a new strip or tolerate your mistake.
Language in Facebook posts may help identify conditions such as diabetes, anxiety, depression and psychosis in patients, according to a study from Penn Medicine and Stony Brook University researchers. It's believed that language in posts could be indicators of disease and, with patient consent, could be monitored just like physical symptoms. This study was published in PLOS ONE.
The formation of air bubbles in a liquid appears very similar to its inverse process, the formation of liquid droplets from, say, a dripping water faucet. But the physics involved is actually quite different, and while those water droplets are uniform in their size and spacing, bubble formation is typically a much more random process.
Now, a study by researchers at MIT and Princeton University shows that under certain conditions, bubbles can also be coaxed to form spheres as perfectly matched as droplets.
Scientists from the University of Massachusetts Amherst, Vanderbilt University and Clark University have shed new light on the genomic foundation of the polar bear's ecological adaption by pinpointing rapid changes in the bear's gene copy numbers in response to a diet shifting from vegetation to meat.
DURHAM, N.C. - Immunotherapies have transformed cancer care, but their successes have been limited for reasons that are both complex and perplexing.
In breast cancer especially, only a small number of patients are even eligible to undergo treatment with immunotherapies, and most see little benefit.
But in a pre-clinical study led by the Duke Cancer Institute, researchers outlined a potential way to improve those results by uncloaking breast cancer tumors to the body's immune system.
Tropical Cyclone Vayu was fading as it neared the coast of southwestern Pakistan and northwestern India. Dry air and wind shear were preventing development the development of thunderstorms, making the clouds on the storm's western side appear wispy in an image from NASA-NOAA's Suomi NPP satellite.
ITHACA, N.Y. - New research from Cornell University offers a new pathway for targeting pathogens in the fight against antibiotic resistant bacteria.
As antibiotic resistance rises, the search for new antibiotic strategies has become imperative. Researchers used the Cornell High Energy Synchotron Source (CHESS) to reveal an unexpected mechanism of activation and inactivation in the protein ribonucleotide reductase (RNR).
The findings were published in "Convergent Allostery in Ribonucleotide Reductase" in Nature Communications.
ITHACA, N.Y. - Cornell University engineers have taken a step in understanding how iron in the soil may unlock naturally occurring phosphorus bound in organic matter, which can be used in fertilizer, so that one day farmers may be able to reduce the amount of artificial fertilizers applied to fields.
PITTSBURGH, June 17, 2019 - A new study from the University of Pittsburgh and UPMC Children's Hospital of Pittsburgh finds that an antibody in breastmilk is necessary to prevent necrotizing enterocolitis (NEC)--an often deadly bacterial disease of the intestine--in preterm infants.
How did the Red Planet get all of its clouds? CU Boulder researchers may have discovered the secret: just add meteors.
Astronomers have long observed clouds in Mars' middle atmosphere, which begins about 18 miles (30 kilometers) above the surface, but have struggled to explain how they formed.
NEW YORK, June 17, 2019 -- The maturation of visual acuity in both amblyopia and myopia may be closely associated with the development of pathways signaling bright features in the brain, according to research published in the Journal of Neuroscience by SUNY College of Optometry doctoral candidate Carmen Pons Torres and colleagues in the laboratory of distinguished professor Dr. Jose-Manuel Alonso.
For the first time, researchers have mapped the building blocks of the human lungs and airways, in both asthma patients and normal people. The research from the Wellcome Sanger Institute, University Medical Center Groningen, Open Targets, GSK and collaborators revealed the identity of each cell type, creating the first draft Human Cell Atlas of the lung. They also discovered an entirely new cell state that produces mucus in asthma patients.
Up to 80% of metastatic colorectal cancers are likely to have spread to distant locations in the body before the original tumor has exceeded the size of a poppy seed, according to a study of nearly 3,000 patients by researchers at the Stanford University School of Medicine.
Identifying patients with early-stage colorectal tumors that are born to be bad may help doctors determine who should receive early treatments, such as systemic chemotherapy, to kill cancer cells lurking far from the tumor's original location.
