New research from bioengineers paints a surprisingly complex picture of limpets - the little seashore creatures that are ubiquitous on rocky patches of beaches in many parts of the world. The bioengineers have discovered that limpets are able to detect minor damage to their shells with surprising accuracy before remodelling them to make them stronger. In many ways, the way they heal is similar to the way broken bones mend in mammals.
CLEVELAND, Ohio (August 29, 2018)--A new study suggests chemotherapy may cause acute amenorrhea leading to early menopause in women with lung cancer. The study is the first to comment on amenorrhea rates in women younger than 50, concluding that women with lung cancer who desire future fertility should be educated about risks and options before starting treatment. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
A tiny pest can cause huge losses to soybean farmers.
Several top soybean producing states in the U.S. are in the Upper Midwest. In these states, an insect-the soybean aphid-is a damaging pest. Each year, soybean aphids cause billions of dollars in crop losses.
In a recent study, researchers have taken a big step toward identifying new soybean genes associated with aphid resistance.
AUSTIN, Texas -- New research from The University of Texas at Austin proves writing letters of gratitude, like Jimmy Fallon's "Thank You Notes," is a pro-social experience people should commit to more often. The gesture improves well-being for not only letter writers but recipients as well.
A team of researchers at the University of Minnesota have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a "bionic eye" that could someday help blind people see or sighted people see better.
The research is published today in Advanced Materials, a peer-reviewed scientific journal covering materials science. The author also holds the patent for 3D-printed semiconducting devices.
Researchers from the University of Hawai'i at Mānoa (UH Mānoa), WCS (Wildlife Conservation Society), and other groups are discovering how forest conservation in Fiji can minimize the impact of human activities on coral reefs and their fish populations.
A system designed by a University of Iowa ophthalmologist that uses artificial intelligence (AI) to detect diabetic retinopathy without a person interpreting the results earned Food and Drug Administration (FDA) authorization in April, following a clinical trial in primary care offices. Results of that study were published Aug. 28 online in Nature Digital Medicine, offering the first look at data that led to FDA clearance for IDx-DR, the first medical device that uses AI for the autonomous detection of diabetic retinopathy.
Ants and humans live in large societies that allow for elaborate structures -- nests, cities -- filled with resources. Sometime in the distant past, individuals must have organized themselves into the first simple groups, precursors of these complex societies. But how?
A team of researchers from Princeton University and Rockefeller University tackled this question by combining sophisticated mathematical models with detailed empirical observations of the clonal raider ant (Ooceraea biroi).
If you've ever experienced jet lag, you are familiar with your circadian rhythm, which manages nearly all aspects of metabolism, from sleep-wake cycles to body temperature to digestion. Every cell in the body has a circadian clock, but researchers were unclear about how networks of cells connect with each other over time and how those time-varying connections impact network functions.
As ocean conservation efforts kick into high gear amid concerns over climate change, food insecurity and habitat degradation, a disturbing phenomenon may also be on the rise: preemptive overfishing in a given area in anticipation of impending conservation policies.
Biodiversity plays a significant role in forest carbon storage, but surprisingly less than previously thought, new research in Ecology Letters suggests.
COLUMBUS, Ohio - Walleye and the fish they eat struggle to see in water clouded by algae, and that could potentially jeopardize the species' future if harmful algal blooms persist, according to a new study.
The research, led by Suzanne Gray of The Ohio State University, found that algae posed more of a threat to adequate vision than an equal amount of sediment - another common cause of murky waters in the western basin of Lake Erie.
DURHAM, N.C. - Over the long-run, the race will indeed go to the slower, steadier animal.
"The fable of 'The Tortoise and the Hare' is a metaphor about life, not a story about a race," said Adrian Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke University. "We see in animal life two starkly different lifestyles -- one with nearly steady feeding and daily sleep and another with short bursts of intermittent feeding interspersed with day-long siestas. Both of these patterns are the rhythms of living that Aesop taught."
Munich, Germany - 27 Aug 2018: The antithrombin drug rivaroxaban does not reduce the risk of a composite endpoint of survival, myocardial infarction and stroke after an episode of worsening heart failure in patients with heart failure, sinus rhythm, and coronary artery disease, according to late breaking results from the COMMANDER HF trial presented today in a Hot Line Session at ESC Congress 20181 and with simultaneous publication in NEJM.
Munich, Germany - 27 Aug 2018: Tafamidis is the first treatment to improve survival and reduce hospitalisations in a rare heart condition called transthyretin amyloid cardiomyopathy, according to late breaking research presented today in a Hot Line Session at ESC Congress 20181 and published in the New England Journal of Medicine.
