Palo Alto, CA-- Understanding how plants respond to stressful environmental conditions is crucial to developing effective strategies for protecting important agricultural crops from a changing climate. New research led by Carnegie's Zhiyong Wang, Shouling, Xu, and Yang Bi reveals an important process by which plants switch between amplified and dampened stress responses. Their work is published by Nature Communications.
A negative experience with food usually leaves us unable to stomach the thought of eating that particular dish again. Using sugar-loving snails as models, researchers at the University of Sussex believe these bad experiences could be causing a switch in our brains, which impacts our future eating habits.
Low-income middle-aged African-American women with hypertension are likely to suffer from depression
Low-income middle-aged African-American women with high blood pressure very commonly suffer from depression and should be better screened for this serious mental health condition, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health.
The researchers found that in a sample of over 300 low-income, African-American women, aged 40-75, with uncontrolled hypertension, nearly 60 percent screened positively for a diagnosis of depression based on a standard clinical questionnaire about depressive symptoms.
New research shows that biodiversity is important not just at the traditional scale of short-term plot experiments--in which ecologists monitor the health of a single meadow, forest grove, or pond after manipulating its species counts--but when measured over decades and across regional landscapes as well. The findings can help guide conservation planning and enhance efforts to make human communities more sustainable.
With the help of the international Gemini Observatory, a Program of NSF's NOIRLab, and other ground-based telescopes, astronomers have confirmed that a faint object discovered in 2018 and nicknamed "Farfarout" is indeed the most distant object yet found in our Solar System. The object has just received its designation from the International Astronomical Union.
Farfarout was first spotted in January 2018 by the Subaru Telescope, located on Maunakea in Hawai'i. Its discoverers could tell it was very far away, but they weren't sure exactly how far. They needed more observations.
ITHACA, N.Y. - As more male-dominated industries look for ways to hire women, new Cornell University research offers employers a simple solution - make your initial job candidate short list longer.
Many professional advancement opportunities - jobs, promotions, trainings and mentorships - are filled through informal recruitment practices. But these practices pose an unintended barrier to gender diversity in male-dominant workplaces because when hiring managers consult their "mental Rolodex," they are more likely to associate certain jobs with specific genders.
Skoltech scientists have proposed a Mass Spectrometry Imaging (MSI) method leveraging the unique features of human vision. The research was published in the journal Analytical Chemistry.
Getting around without the need to concentrate on every step is something most of us can take for granted because our inner ears drive reflexes that make maintaining balance automatic. However, for about 1.8 million adults worldwide with bilateral vestibular hypofunction (BVH) -- loss of the inner ears' sense of balance -- walking requires constant attention to avoid a fall.
For some 15,000 years, dogs have been our hunting partners, workmates, helpers and companions. Could they also be our next allies in the fight against COVID-19?
According to UC Santa Barbara professor emeritus Tommy Dickey(link is external) and his collaborator, BioScent researcher Heather Junqueira, they can. And with a review paper(link is external) published in the Journal of Osteopathic Medicine they have added to a small but growing consensus that trained medical scent dogs can effectively be used for screening individuals who may be infected with the COVID-19 virus.
DURHAM, N.C. - People who have a gene variant associated with an increased risk of developing Alzheimer's disease also tend to have changes in the fluid around their brain and spinal cord that are detectable years before symptoms arise, according to new research from Duke Health.
New research from the Indiana University Kelley School of Business shows first evidence that watching and learning from others can help reduce bias and improve decision-making.
Irvine, CA - February 11, 2021 - Subconsciously, our bodies keep time for us through an ancient means - the circadian clock. A new University of California, Irvine-led article reviews how the clock controls various aspects of homeostasis, and how organs coordinate their function over the course of a day.
Space: the final frontier. What's stopping us from exploring it? Well, lots of things, but one of the major issues is space radiation, and the effects it can have on astronaut health during long voyages. A new review in the open-access journal Frontiers in Cardiovascular Medicine explores what we know about the ways that space radiation can negatively affect cardiovascular health, and discusses methods to protect astronauts.
A new study published in the journal Science Advances shows that Bantu-speaking communities in the Congo rainforest underwent a major population collapse from 1600 to 1400 years ago, probably due to a prolonged disease epidemic, and that significant resettlement did not restart until around 1000 years ago.
Birdwatchers get very excited when a 'rare' migratory bird makes landfall having been blown off-course and flown beyond its normal range. But these are rare for a reason; most birds that have made the journey before are able to correct for large displacements and find their final destination.
Now, new research by an international team shows for the first time, how birds displaced in this way are able to navigate back to their migratory route and gives us an insight into how they accomplish this feat.
