Chronic stress can lead to behavioral problems. A team of researchers has discovered an important synaptic mechanism: the activation of a cleaving enzyme, leading to these problems.
Considered to be at the forefront of microscopy technology in agriculture, the Donald Danforth Plant Science Center in St. Louis, Missouri supports education, industry and innovation under one roof.
Creating unmown areas in an urban park can significantly increase flowers and pollinating insects while also leading to a greater enjoyment of the space by people, according to a year-long study.
Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that they would have an optimistic outlook on life. But, some dogs are distinctly more pessimistic than others.
A genetically engineered tobacco plant, developed with two genes from blue-green algae holds promise for improving the yields of many food crops.
Ensuring that corn absorbs the right balance of nitrogen, phosphorus and potassium is crucial to increasing global yields. A review of data from more than 150 studies from the U.S. and other regions showed that high yields were linked to production systems in which corn plants took up key nutrients at specific ratios— nitrogen and phosphorus at a ratio of five-to-one and nitrogen and potassium at a ratio of one-to-one.
A wild berry native to North America may strengthen the effectiveness of a chemotherapy drug commonly used to treat pancreatic cancer. A new study suggests that adding nutraceuticals to chemotherapy cycles may improve the effectiveness of conventional drugs, particularly in hard to treat cancers.
Think the flu's only a big threat to kids and seniors? Influenza hospitalized a surprisingly high number of young and middle-aged adults last winter— and this time around, the government wants more of them vaccinated.
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity.
New studies of ancient DNA are shifting scientists' ideas of how groups of people migrated across the globe and interacted with one another thousands of years ago. By comparing nine ancient genomes to those of modern humans, scientists have shown that previously unrecognized groups contributed to the genetic mix now present in most modern-day Europeans.
Using artificial sweeteners may set the stage for diabetes in some people by hampering the way their bodies handle sugar, suggests a preliminary study done mostly in mice. The researchers and outside experts said more study is needed, while industry groups called the research limited and said other evidence shows sweeteners are safe and useful for weight control.
The idea of the Ebola virus becoming airborne is not far-fetched as its ability to enter cells that line the trachea and lungs has been shown under controlled laboratory conditions, a virus expert says.
Up to 80 percent of sexually active women are infected by the human papillomavirus at some point in their lives and infection with specific "high risk" strains of HPV has an established link to cervical cancer. Current screening by smear test is invasive and time-consuming. Urine samples may be a viable alternative.
Polish medical experts say that the preserved heart of 19th century composer Frederic Chopin shows signs of tuberculosis and possibly some other lung disease.
A new study into meat tenderness could refine the way people cook steak. Researchers conducted studies using microscopes to see what happens to meat cells while being cooked. They found that meat shrinks while cooking not once but twice.
The amazing variety of human faces– far greater than that of most other animals– is the result of evolutionary pressure to make each of us unique and easily recognizable. Our highly visual social interactions are almost certainly the driver of this evolutionary trend.
The meteorite impact that spelled doom for the dinosaurs 66 million years ago decimated the evergreens among the flowering plants to a much greater extent than their deciduous peers. Researchers have found evidence that, after the event, fast-growing, deciduous angiosperms had replaced their slow-growing, evergreen peers to a large extent.
Scientists working together around the world have discovered a significant link between genetic changes near the ROBO2 gene and the number of words spoken by children in the early stages of language development.
A colossal squid weighing 770 pounds, as long as a minibus and one of the sea's most elusive species was caught by fishermen. It was frozen for eight months until today, when scientists in New Zealand got a long-anticipated chance to thaw out the animal and inspect it. About 142,000 people from 180 countries watched streaming footage of the squid examination on the Internet.
Starting next month, America's remaining tobacco growers will be totally exposed to the laws of supply and demand. The last buyout checks, totaling about $916.5 million, go out in October to about 425,000 tobacco farmers and landowners. They're the last holdovers from a price-support and quota system that had guaranteed minimum prices for most of the 20th century.
A peek inside the brains of more than 750 children and teens has revealed a key difference in brain architecture between those with attention deficit hyperactivity disorder and those without. Kids and teens with ADHD lag behind others of the same age in how quickly their brains form connections within— and between— key brain networks.
During cancer development, tumor cells decorate their surfaces with sugar compounds called glycans that are different from those found on normal, healthy cells. New research has found that sialic acids at the tips of these cancer cell glycans are capable of engaging with immune system cells and changing the latter’s response to the tumor– for good and bad.
New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms. The finding could be a first step toward improved diagnosis and treatment for the debilitating psychiatric illness.
Jeanne Calment, who died in 1997 at the age of 122, remains the oldest person on record. One might assume that she led a faultless, healthy lifestyle. Not at all. Instead, scientists have discovered that longevity is prevalent in certain families and the focus is now on discovering the genes— or the DNA instructions— that favor a long, healthy life.
Sixteen years after scientists found the genes that control the circadian clock in all cells, researchers have discovered the mechanisms responsible for keeping the clock in sync. The find has implications for the development of drugs for various diseases such as cancers and diabetes, as well as conditions such as metabolic syndrome, insomnia, seasonal affective disorder, obesity and even jetlag.
