People in crowded urban areas - especially poor areas - see fewer songbirds such as tits and finches, and more potential "nuisance" birds, such as pigeons, magpies and gulls, new research shows.
The University of Exeter and the British Trust for Ornithology examined ratios of birds-to-people and found areas of high-density housing have fewer birds overall - and the birds people do see are just as likely to cause a nuisance as to make them happy.
Engineers have proposed a coordinated control architecture for motion management in advanced driver assistance systems (ADAS) to increase safety and comfort across all vehicles, regardless of ADAS specifics.
They published their proposal in IEEE/CAA Journal of Automatica Sinica, a joint publication of the IEEE and the Chinese Association of Automation.
In 2013, the Nobel Prize in Physiology or Medicine was awarded to three scientists for their contributions to uncovering the mechanisms governing vesicle transport in cells. Their explanations provided both a conceptual and a mechanistic understanding of basic processes at the most fundamental level.
BUFFALO, N.Y. -- Each year, farmers in the U.S. purchase tens of millions of pounds of antibiotics that are approved for use in cows, pigs, fowl and other livestock.
When farmers repurpose the animals' manure as fertilizer or bedding, traces of the medicines leach into the environment, raising concerns that agriculture may be contributing to the rise of antibiotic-resistant bacteria.
New research holds troublesome insights with regard to the scope of this problem.
Researchers at the University of Washington have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities.
The research finding was first published in ACS Biomaterials Science and Engineering.
"Remineralization guided by peptides is a healthy alternative to current dental health care," said lead author Mehmet Sarikaya, professor of materials science and engineering and adjunct professor in the Department of Chemical Engineering and Department of Oral Health Sciences.
Things are getting real for researchers in the UC Santa Barbara John Martinis/Google group. They are making good on their intentions to declare supremacy in a tight global race to build the first quantum machine to outperform the world's best classical supercomputers.
But what is quantum supremacy in a field where horizons are being widened on a regular basis, in which teams of the brightest quantum computing minds in the world routinely up the ante on the number and type of quantum bits ("qubits") they can build, each with their own range of qualities?
About a year and a half ago, a 6-year-old boy arrived at Children's Emergency Department after accidently removing his own gastrointestinal feeding tube. He wasn't a stranger to Children's National Health System: This young patient had spent plenty of time at the hospital since birth. Diagnosed in infancy with an intestinal pseudo-obstruction, a rare condition in which his bowels acted as if there were a blockage even though one was not present, parts of his intestine died and had been removed through multiple surgeries.
UCLA biochemists have achieved a first in biology: viewing at near-atomic detail the smallest protein ever seen by the technique whose development won its creators the 2017 Nobel Prize in chemistry. That technique, called cryo-electron microscopy, enables scientists to see large biomolecules, such as viruses, in extraordinary detail.
First study to show 'owls' have higher risk of mortality
Switch to daylight savings time is much harder for them
They suffer from more diseases and disorders than morning larks
Employers should allow greater flexibility in working hours
Consider abolishing daylight savings time, scientists say
Deep space is not as silent as we have been led to believe. Every few minutes a pair of black holes smash into each other. These cataclysms release ripples in the fabric of spacetime known as gravitational waves. Now Monash University scientists have developed a way to listen in on these events. The gravitational waves from black hole mergers imprint a distinctive whooping sound in the data collected by gravitational-wave detectors. The new technique is expected to reveal the presence of thousands of previously hidden black holes by teasing out their faint whoops from a sea of static.
Analyzing the famous academic aphorism "publish or perish" through a modern digital lens, a group of emerging ecologists and conservation scientists wanted to see whether communicating their new research discoveries through social media--primarily Twitter--eventually leads to higher citations years down the road.
Turns out, the tweets are worth the time investment.
How do you measure a chemical compound that lasts for less than a second in the atmosphere?
URBANA, Ill. - When a natural disaster strikes, major disaster databases tend to compile information about losses such as damages to property or cost of repairs, but other economic impacts after the disaster are often overlooked--such as how a company's lost ability to produce products may affect the entire supply-chain within the affected region and in other regions.
British researchers have discovered a hormone imbalance that explains why it is very difficult to control blood pressure in around 10 per cent of hypertension patients.
The team, led by Queen Mary University of London, found that the steroid hormone 'aldosterone' causes salt to accumulate in the bloodstream. The salt accumulation occurs even in patients on reasonable diets, and pushes up blood pressure despite use of diuretics and other standard treatments.
The divide that separates conservative and liberal values may be as wide now as it has ever been in our country. This divide shows itself in areas of everyday life, and health care is no exception.
But do doctors' political beliefs influence the way they practice medicine, choose therapies and treat patients?
