The Goldilocks of fairy-tale fame knew something about porridge. It needed to be just right--neither too hot nor too cold. Same with furniture--neither too hard nor too soft. In a different context, scientists at UC San Diego know something about DNA. They know that the strands of our genetic code, if extended, would measure two meters, or about six feet. They also know that the strands fold into and move within the cell nucleus the size of about a hundredth of a millimeter. But they don't know how and in what state of matter this occurs, so they decided to check.
A new publication in the journal Estuaries and Coasts investigates the use of a fluorescent dye to track movements of young oysters. The publication, "Field mark-recapture of calcein-stained larval oysters (Crassostrea virginica) in a freshwater-dominated estuary", provides new knowledge on methods for tracking oysters in low salinity environments common to coastal waters, particularly in the northern Gulf of Mexico.
Monarch butterflies purchased from a commercial breeder did not fly in a southward direction, even in offspring raised outdoors, in a new study conducted by scientists at the University of Chicago. Wild-caught monarchs bred indoors under simulated outdoor conditions also did not orient south, suggesting that captive breeding disrupts the monarch's famous annual migratory behavior.
Following a stroke, antibodies that inhibit the signaling molecule Nogo-A can help repair blood vessels in the affected brain regions. This also promotes the regaining of motor functions, researchers at the University of Zurich have shown in a mouse model. The study opens up new avenues for treatment.
BROOKLYN, New York, Monday, June 24, 2019 – For the first time, researchers have shown a causal link between print news media coverage of U.S. gun control policy in the wake of mass shooting events and increases in firearm acquisition, particularly in states with the least restrictive gun laws.
BOSTON - June 24, 2019 -- A study by scientists at Boston Children's Hospital and Brigham and Women's Hospital, published today in Nature Medicine, makes a strong case that the national epidemic of food allergy is caused by the absence of certain beneficial bacteria in the human gut. "The loss of these bacteria acts as a switch that makes children susceptible to food allergy," says Talal Chatila, MD, director of the Food Allergy Program at Boston Children's and a senior author on the paper.
You might expect that plants hoping to thrive in California's boom-or-bust rain cycle would choose to set down roots in a place that can store lots of water underground to last through drought years.
But some of the most successful plant communities in the state -- and probably in Mediterranean climates worldwide -- that are characterized by wet winters and dry summers have taken a different approach. They've learned to thrive in areas with a below-ground water storage capacity barely large enough to hold the water that falls even in lean years.
ANAHEIM, CA (Embargoed until 4:30 p.m. PDT, Saturday, June 22, 2019) - Researchers have discovered a novel radioligand that can effectively differentiate progressive supranuclear palsy (PSP) from similar brain disorders, allowing for earlier and more reliable diagnosis of the disease. Presented at the Society of Nuclear Medicine and Molecular Imaging's 2019 Annual Meeting, these findings bring physicians a step closer to being able to definitively diagnose PSP with imaging rather than waiting for confirmation upon autopsy.
ANAHEIM, CA - A first-in-human Phase 1/Phase II study demonstrates that intravenous administration of the radiopharmaceutical imaging agent technetium-99m (99mTc) tilmanocept promises to be a safe, well-tolerated, noninvasive means of monitoring rheumatoid arthritis disease activity. At present, there is no reliable noninvasive way to directly monitor inflammation in joints of RA patients. The study was presented at the 2019 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI).
Some MRSA infections could be tackled using widely-available antibiotics, suggests new research from an international collaboration led by scientists at the University of Cambridge and the Wellcome Sanger Institute.
New research led by climate scientists from the University of Bristol suggests that the representation of clouds in climate models is as, or more, important than the amount of greenhouse gas emissions when it comes to projecting future Greenland ice sheet melt.
Recent research shows that the whole of the Greenland ice sheet could be gone within the next thousand years, raising global sea level by more than seven metres.
Vienna, 24 June 2019: The increasingly popular trend for fertility clinics to freeze all IVF embryos for later transfer has been shown in a large multicentre randomised trial to offer no improvement in delivery rates over traditional 'fresh' embryo transfers. 'Our findings give no support to a general freeze-all strategy in normally menstruating women,' said investigator Dr Sacha Stormlund from Copenhagen University Hospital in Denmark, who presents the results today at the 35th Annual Meeting of ESHRE.
An induced feeling of awe, or state of wonder, may be the best strategy yet for alleviating the discomfort that comes from uncertain waiting.
Kate Sweeny's research explores the most excruciating form of waiting: the period during which one awaits uncertain news, the outcome of which is beyond one's control. It's waiting for news from a biopsy, or whether you aced -- or tanked -- the exam. That's distinguished from waiting periods such as when looking for a new job, when you have at least some control over the outcome.
High school students who take music courses score significantly better on math, science and English exams than their non-musical peers, according to a new study published in the Journal of Educational Psychology.
School administrators needing to trim budgets often look first to music courses, because the general belief is that students who devote time to music rather than math, science and English, will underperform in those disciplines.
One of the most challenging issues for game players looks to be resolved soon with the introduction of a zero-latency gaming environment. A KAIST team developed a technology that helps game players maintain zero-latency performance. The new technology transforms the shapes of game design according to the amount of latency.
