As a cutting-edge subject in the cross research field, solid high-order harmonics not only provide a new strategy for high-efficiency, wide energy spectrum, short pulse light source, but also can be used to better study the electronic structure and nonlinear optical properties of condensed matter.
The greater sage-grouse is an iconic bird that lives in the western United States, and its populations are in decline. A new study published in the Journal of Wildlife Management reveals that energy development has negative impacts on sage-grouse reproduction.
Imagine purchasing products from your local grocer, only to find out that those products are comprised of critically endangered species! That's what a team from the University of Hong Kong, Division of Ecology and Biodiversity has recently discovered on Hong Kong supermarket shelves. A team led by Dr David Baker from the University's Conservation Forensics laboratory, has recently published the results from an investigation into European eel products on sale in Hong Kong supermarkets.
Many studies seek to estimate the adverse effects of climate change on crops, but most research assumes that the geographic distribution of crops will remain unchanged in the future.
New research using 40 years of global data, led by Colorado State University, has found that exposure to rising high temperatures has been substantially moderated by the migration of rainfed corn, wheat and rice. Scientists said continued migration, however, may result in significant environmental costs.
Researchers at the University of Texas Southwestern Medical Center and University of Chicago have discovered that bacteria that usually live in the gut can accumulate in tumors and improve the effectiveness of immunotherapy in mice.
Military spouses can struggle to find and maintain employment and face severe restrictions on their social lives because of their partners' working patterns.
New research from Lancaster University and the University of Manchester, published in the European Journal of Marketing, studied the wives of British Army personnel.
WEST LAFAYETTE, Ind. -- By 2030, global warming alone could push Chicago to generate 12% more electricity per person each month of the summer.
Any less than that, and the city would be risking a power shortage that may require drastic measures to avoid rolling blackouts, according to projections from a model designed by Purdue University researchers.
Chemotherapy halves the risk of a rare form of kidney cancer coming back after surgery, the largest ever trial conducted in the disease worldwide has found.
Patients given chemotherapy within three months of surgery saw the risk of their cancer coming back or spreading reduced and were much more likely to live cancer free for three years or more.
In a study of epilepsy patients, researchers at the National Institutes of Health monitored the electrical activity of thousands of individual brain cells, called neurons, as patients took memory tests. They found that the firing patterns of the cells that occurred when patients learned a word pair were replayed fractions of a second before they successfully remembered the pair. The study was part of an NIH Clinical Center trial for patients with drug-resistant epilepsy whose seizures cannot be controlled with drugs.
Collaboration is everything - also in the quantum world. To build powerful quantum computers in the future, it will be necessary to connect several smaller computers to form a kind of cluster or local network (LAN). Since those computers work with quantum mechanical superposition states, which contain the logical values "0" and "1" at the same time, the links between them should also be "quantum links".
The news in brief:
1) Red Sea corals and especially corals of the Gulf of Aqaba in the northern Red Sea may be one of the last reefs to survive the century. Scientists estimate 70 to 90 percent of all coral reefs will disappear by mid-century, primarily as a result of climate change and pollution.
Our day-to-day lives can be seen as a series of complex motor sequences: morning routines, work or school tasks, actions we take around mealtimes, the rituals and habits woven through our evenings and weekends. They seem almost automatic, with little conscious thought behind them.
In reality, however, they are the result of the myriad decisions and physical adjustments we make along the way, thanks to the continual signal processing in the brain that is guided by information we receive through our senses.
CORVALLIS, Ore. - Tapping into 35 years of satellite imagery, researchers at Oregon State University have dramatically enlarged the database regarding how climate change is affecting kelps, near-shore seaweeds that provide food and shelter for fish and protect coastlines from wave damage.
And the Landsat pictures paved the way to some surprising findings: A summer of warm water isn't automatically bad news for kelps, and large winter waves aren't either.
The study was published in Ecology.
Myocardial blood flow (MBF) and myocardial flow reserve (MFR) have been identified as accurate indicators for graft failure after cardiac transplantation, according to a new study published in The Journal of Nuclear Medicine. Utilizing positron emission tomography (PET) myocardial perfusion imaging to quantify MBF and MRF, researchers were able to successfully detect patients with cardiac allograft vasculopathy (CAV), the most serious condition facing transplant patients late after their surgery.
Some of the first animals on Earth were connected by networks of thread-like filaments, the earliest evidence yet found of life being connected in this way.
Scientists from the Universities of Cambridge and Oxford discovered the fossilised threads - some as long as four metres - connecting organisms known as rangeomorphs, which dominated Earth's oceans half a billion years ago.
