As well as bright colours and subtle scents, flowers possess many invisible ways of attracting their pollinators, and a new study shows that bumblebees may use the humidity of a flower to tell them about the presence of nectar, according to scientists at the Universities of Bristol and Exeter.
This new research has shown that bumblebees are able to accurately detect and choose between flowers that have different levels of humidity next to the surface of the flower.
Coastal wetlands like seagrass meadows, mangroves, and salt marshes play vital roles along the shoreline, from providing a buffer against storm surges, to providing critical habitat for animals, to capturing atmospheric carbon.
WASHINGTON, June 22, 2021 -- About 2.2 billion people globally lack reliable access to clean drinking water, according to the United Nations, and the growing impacts of climate change are likely to worsen this reality.
A team of scientists from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has now discovered that the odorant receptor OR5K1 is specialized to recognize pyrazines in both humans and domesticated animals. These are volatile substances that contribute to the typical odor of many vegetables or are formed when food is heated. In addition, pyrazines also play a role as signaling substances in intra- or interspecific communication.
A single measurement result is not a proof - this has been shown again and again in science. We can only really rely on a research result when it has been measured several times, preferably by different research teams, in slightly different ways. In this way, errors can usually be detected sooner or later.
Cancer cells can become resistant to treatments through adaptation, making them notoriously tricky to defeat and highly lethal. Cold Spring Harbor Laboratory (CSHL) Cancer Center Director David Tuveson and his team investigated the basis of "adaptive resistance" common to pancreatic cancer. They discovered one of the backups to which these cells switch when confronted with cancer-killing drugs.
The shift to home working brought about by the pandemic could cost the UK economy up to £32bn a year in lost personal income tax.
Highly paid workers who live abroad but work in the UK will pay their income tax in their country of residence, rather than to HMRC - which researchers say could cost billions each year.
This new mobility of the workforce can also affect where corporate income tax is paid and value created, as well as VAT and where goods and services are purchased.
(SACRAMENTO, Calif.) -- The secret to healthier skin and joints may reside in gut microorganisms. A study led by UC Davis Health researchers has found that a diet rich in sugar and fat leads to an imbalance in the gut's microbial culture and may contribute to inflammatory skin diseases such as psoriasis.
Large thunderstorms in the Southern Great Plains of the U.S. are some of the strongest on Earth. In recent years, these storms have increased in frequency and intensity, and new research shows that these shifts are linked to climate variability.
Co-authored by Christopher Maupin, Courtney Schumacher and Brendan Roark, all scientists in Texas A&M University's College of Geosciences, along with other researchers, the findings were recently published in Nature Geoscience.
A research team from Northwestern Engineering and the University of Messina in Italy have developed a new magnetic memory device that could lead to faster, more robust Artificial Intelligence (AI) systems. Composed of antiferromagnetic materials, the memory technology is immune to external magnetic fields and could one day improve a variety of computing systems, including AI hardware, cryptocurrency mining, and space exploration programs.
Poll of 1,161 Ontario students shows attitudes toward cannabis differ from alcohol, creating potentially risky and dangerous driving behaviour
Ontario students are more likely to get behind the wheel of a vehicle after smoking cannabis than drinking alcohol, a new study from researchers at the University of Ottawa's Faculty of Medicine has revealed.
Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth's atmosphere are not equal to the climate changes from deliberate CO2 removals--and assuming such a balance could lead to different climate outcomes that may skew climate targets, according to new Simon Fraser University-led research.
New York, NY--June 22, 2021--Because corporations and governments rely on computers and the internet to run everything from the electric grid, healthcare, and water systems, computer security is extremely important to all of us. It is increasingly being breached: Numerous security hacks just this past month include the Colonial Pipeline security breach and the JBS Foods ransomware attacks where hackers took over the organization's computer systems and demanded payment to unlock and release it back to the owners.
As you drive down the highway, you may notice an increasing number of hybrid and electric vehicles. Alternative energy automobiles are on the rise contributing to the global effort to reduce carbon emissions. As we move together down this road, researchers are looking to determine new solutions to this ongoing problem.
Engineers at Duke University have devised a system for manipulating particles approaching the miniscule 2.5 nanometer diameter of DNA using sound-induced electric fields. Dubbed "acoustoelectronic nanotweezers," the approach provides a label-free, dynamically controllable method of moving and trapping nanoparticles over a large area. The technology holds promise for applications in the fields ranging from condensed matter physics to biomedicine.
The research appears online on June 22 in Nature Communications.
