The ocean is getting too loud even for crabs. Normally, shore crabs (Carcinus maenas) can slowly change their shell color to blend in with the rocky shores in which they live, but recent findings show that prolonged exposure to the sounds of ships weakens their camouflaging powers and leaves them more open to attack. The work, appearing March 9 in the journal Current Biology, illustrates how man-made undersea noise can turn common shore crabs into sitting ducks for potential predators.
Colour-changing crabs struggle to camouflage themselves when exposed to noise from ships, new research shows.
Shore crabs - the most common on UK shores - can change colour to match their surroundings.
But University of Exeter scientists have discovered that crabs exposed hourly to ship noise change colour half as quickly. As a result, they don't match the background as closely.
What The Study Did: The risk of physical and sexual violence faced by gay, lesbian, bisexual and questioning U.S. high schoolers was quantified in this observational study that used pooled data from a survey conducted every two years by the Centers for Disease Control and Prevention.
Author: Theodore L. Caputi, M.P.H., of Harvard Medical School, Cambridge Health Alliance in Cambridge, Massachusetts, is the corresponding author.
A world-first study, led by Australia's Monash University, has patented a new filtration technique that could slash lithium extraction times.
The research team has developed a synthetic MOF-based membrane that can filter lithium ions in an ultra-fast and highly selective manner.
Preliminary studies have shown this technology has a lithium recovery rate of approximately 90 per cent.
An international research team has pioneered and patented a new filtration technique that could one day slash lithium extraction times and change the way the future is powered.
HOUSTON - (March 9, 2020) - A novel system to amplify gene expression signals could be a game-changer for scientists who study the regulatory processes in cells that are central to all life.
The Rice University lab of bioscientist Laura Segatori has developed a versatile gene signal amplifier that can do a better job of detecting the expression of target genes than current methods.
PULLMAN, Wash. - A breakthrough into splitting water into its parts could help make renewable energy pay off, even when the sun isn't shining and the wind isn't blowing.
Using solar and wind power when it is available for water splitting, a process that uses electricity to split H2O into hydrogen and oxygen, offers a way to store energy in the form of hydrogen fuel.
One of the most challenging tasks for drivers is parallel parking, which is why automatic parking systems are becoming a popular feature on some vehicles. However, the cost of designing and implementing such computing-intensive systems can significantly increase a vehicle's price, creating a barrier to adding the feature in many models.
Optical fibers enable our era of the internet, as they carry vast amounts of data all around the world. Fibers are also an excellent sensor platform. They can reach over hundreds of kilometers, simply embedded within structures, and can be installed in hazardous environment where the use of electricity is prohibited. However, optical fiber sensors also face an inherent, fundamental challenge.
COLUMBUS, Ohio - Go ahead and be grateful for the good things in your life. Just don't think that a gratitude intervention will help you feel less depressed or anxious.
In a new study, researchers at The Ohio State University analyzed results from 27 separate studies that examined the effectiveness of gratitude interventions on reducing symptoms of anxiety and depression.
The results showed that such interventions had limited benefits at best.
It is a project geared towards the study of cancer, melanoma and breast cancer, in particular, and seeks to better understand the growth and dynamics of tumours, which also avoids the need for animal experiments. 4DbioSERS is a five-year project funded by 2.4 million euros from the European Research Council (ERC) as part of the prestigious ERC Advanced Grants call awarded to high-risk and high-gain projects.
Certain purchases are better than others at sparking people's in-the-moment happiness, according to new research from the McCombs School of Business at The University of Texas at Austin.
Lead author Amit Kumar, assistant professor of marketing, and his research team found that consumers are happier when they spend on experiential purchases versus material ones. The paper, "Spending on Doing Promotes More Moment-to-Moment Happiness than Spending on Having," is published in the May 2020 issue of the Journal of Experimental Social Psychology.
A collaborative approach is required to build health care pathways that will end homelessness in Canada. Clinicians can play a role by tailoring their interventions using a comprehensive new clinical guideline on homelessness published in CMAJ (Canadian Medical Association Journal).
Researchers from King's College London & Homerton University Hospital have found babies born before 32 weeks' gestation can rapidly acquire some adult immune functions after birth, equivalent to that achieved by infants born at term.
Experts discover a new 'toolkit' of proteins which can repair breaks in DNA.?
An accumulation of DNA breaks can cause ageing, cancer and Motor Neurone Disease (MND).?
The finding could also help repair DNA breaks caused deliberately during chemotherapy treatment to kill cancerous cells.
A new 'toolkit' to repair damaged DNA that can lead to ageing, cancer and Motor Neurone Disease (MND) has been discovered by scientists at the Universities of Sheffield and Oxford.
A new study says that hurricanes Irma and Maria combined in 2017 to knock down a quarter of the biomass contained in Puerto Rico's trees -- and that massive rainfall, more than wind, was a previously unsuspected key factor. The surprising finding suggests that future hurricanes stoked by warming climate may be even more destructive to forests than scientists have already projected. The study appears this week in the journal Scientific Reports.
