New research led by scientists from the University of Bristol and Queen Mary University of London has revealed that bumblebees can tell flowers apart by patterns of scent.
Flowers have lots of different patterns on their surfaces that help to guide bees and other pollinators towards the flower's nectar, speeding up pollination.
These patterns include visual signals like lines pointing to the centre of the flower, or colour differences.
New findings from the long-running Whitehall II study of over 10,000 civil servants has found 50-year-olds who had blood pressure that was higher than normal but still below the threshold commonly used when deciding to treat the condition, were at increased risk of developing dementia in later life.
This increased risk was seen even when the study participants did not have other heart or blood vessel-related problems, according to the research, which is published in the European Heart Journal [1] today (Wednesday).
Researchers at the University of Bristol have discovered that more sociable fish suppress their own personality when they are with a partner.
Fish, much like humans, exhibit a wide range of different personalities. Individuals vary in qualities such as how social they are and their willingness to take risk (boldness).
The new study, published today in the journal Proceedings of the Royal Society B, was carried out on three-spined sticklebacks.
Recipe for the perfect balance of breaks and repairs in our genome could help fight cancer and brain ageing
New discovery gives insight into chemotherapy resistant cancers such as rhabdosarcoma - the most common soft tissue cancer in children
Findings could have significant implications in brain ageing which has an effect on memory and cognitive function
June 12, 2018 - CHAPEL HILL, N.C. -- Heart defects are the most common type of birth defect, and can be caused by mutations in the gene CHD4. Researchers at the UNC School of Medicine have now revealed key molecular details of how CHD4 mutations lead to heart defects.
A University of Central Florida team has designed a nanostructured optical sensor that for the first time can efficiently detect molecular chirality - a property of molecular spatial twist that defines its biochemical properties.
Determining chirality is critical for new drug development.
A new scientific report from an international team of psychological researchers aims to resolve the so-called "reading wars," emphasizing the importance of teaching phonics in establishing fundamental reading skills in early childhood.
People with higher empathy differ from others in the way their brains process music, according to a study by researchers at Southern Methodist University, Dallas and UCLA.
The researchers found that compared to low empathy people, those with higher empathy process familiar music with greater involvement of the reward system of the brain, as well as in areas responsible for processing social information.
DURHAM, N.C. -- Efforts to address social inequalities in income, education and employment opportunity can be boosted simply by the manner in which that inequity is presented, according to new research from Duke University's Fuqua School of Business.
If you benefit from an inequity, how you handle the situation could depend upon how it is described to you, Professor Ashleigh Shelby Rosette found.
Her study tested people's willingness to surrender part of a bonus at work as a way of studying the presentation of an unjust imbalance or inequity.
The decision to claim credit for a cyberattack on a government or institution depends on both the goals of the attack and the characteristics of the attacker, according to a study co-authored by a UConn political scientist that is one of the first to look into the voluntary claiming of cybersecurity operations.
WASHINGTON -- A systemwide change to the culture and climate in higher education is needed to prevent and effectively respond to sexual harassment, says a new report from the National Academies of Sciences, Engineering, and Medicine. There is no evidence that current policies, procedures, and approaches - which often focus on symbolic compliance with the law and on avoiding liability -- have resulted in a significant reduction in sexual harassment.
To prevent and treat Alzheimer's disease, scientists need to better understand how the disease differs between women and men, according to a paper published June 12 in Alzheimer's & Dementia: The Journal of the Alzheimer's Association.
Despite efforts to eradicate it, syphilis is on the rise. Until now, most health agencies focused on treating infected people and their sex partners but new discoveries may make a vaccine possible, UConn Health researchers report in the 12 June issue of mBio.
Every time we send an e-mail, a tweet, or stream a video, we rely on laser light to transfer digital information over a complex network of optical fibers. Dozens of high-performance lasers are needed to fill up the bandwidth and to squeeze in an increasing amount of digital data. Researchers have now shown that all these lasers can be replaced by a single device called a microcomb.
Doctors are increasingly fighting cancer by stimulating patients' immune systems. SNSF-supported researchers have now discovered a method for predicting the likelihood of treatment success.
Immunotherapy changes a patient's immune system to allow it to attack cancer cells and either destroy them or at least keep them from growing. But the therapy only works for a minority of patients. Researchers supported by the Swiss National Science Foundation (SNSF) have now discovered how to better predict who will respond to the therapy and who will not.
