In California's Central Valley, just as many bird species use riparian habitats in the winter as in the summer, and genetic diversity is actually higher in the winter than during summer months, research shows.
Researchers are calling for improvements to the way early miscarriage is diagnosed, following a new study. An accurate diagnosis is vital since a misdiagnosis could result in a healthy pregnancy being inadvertently terminated. The current standard for diagnosis may require a single ultrasound scan or two scans with the second occurring after a seven days.
Treatment with clomiphene, a standard therapy for couples with unexplained infertility, results in more live births than treatment with a potential alternative, letrozole, according to a study of more than 900 couples.
The ability to walk has been restored following a spinal cord injury, using one's own brain power, according to research. The preliminary proof-of-concept study shows that it is possible to use direct brain control to get a person's legs to walk again.
A computer scientist will use three grants to develop approaches to safeguarding sensitive genetic information. Along with co-researchers, he will systematically evaluate potential privacy breaches due to released genomic statistics and analyses. They will design genetic privacy course modules and hands-on projects on privacy infringement and protection to enhance genetic privacy education in computer science, bioinformatics and genomics.
For the past 27 years, cord blood transplants have been a life-saving treatment option for thousands of people with leukemia, non-Hodgkins lymphoma, Hodgkins disease and myelodysplastic disorders. Cord blood helps replace cancerous blood cells and replenish a patient's own bone marrow and immune system. Researchers have now completed a pilot clinical trial that tested the use of hyperbaric oxygen therapy to improve the outcomes of umbilical cord blood transplant patients, with positive results.
The inventor of the lithium-ion battery, and his team of researchers, have identified a new cathode material made of the nontoxic and inexpensive mineral eldfellite for sodium-ion batteries.
A new strategy has been developed for meeting one of today's most significant challenges in genomic medicine - determining whether a specific DNA variant in the non-protein-coding genome is the actual cause of an associated disease risk.
For certain cancer drugs, participants in clinical trials are often not representative of the patients that ultimately take the drugs, raising questions about the direct applicability of trial data, a new article explains.
As much as 47 percent of the edible US seafood supply is lost each year, mainly from consumer waste, new research suggests. The findings come as food waste in general has been in the spotlight and concerns have been raised about the sustainability of the world's seafood resources. In the U.S. and around the world, people are being advised to eat more seafood, but overfishing, climate change, pollution, habitat destruction and the use of fish for other purposes besides human consumption threaten the global seafood supply.
By studying a system that couples matter and light together, like the universe itself, researchers have now found that crossing a quantum phase transition at intermediate speeds generates the richest, most complex structure. Such structure resembles 'defects' in an otherwise smooth and empty space.
If you read a report whose message was that people consume too much, would you then be likely to curb your own consumption? In some cases yes, says a new study. According to the study, people who place a high value on materialism are likely to reduce their consumption after reading such a report.
The findings of a new study may provide a new way of treating kidney cancer, opening the potential for more potent and less toxic therapies that would give cancer patients a better quality of life.
To encourage consumers to lower their caloric intake, the US Food and Drug Administration now requires most chain restaurants to state the number of calories that each menu item contains. But is a number the only effective way of helping diners make low-calorie choices? No, says a new study. According to the study, another popular way of indicating calorie information, an image of a green, yellow, or red traffic light, can be just as effective.
People who get dizzy several minutes after standing up may be at risk of more serious conditions and even an increased risk of death, according to new research. Feeling dizzy, faint or light-headed after standing due to a sudden drop in blood pressure can be a minor problem due to medication use or dehydration. But when it happens often, it can be a sign of a more serious condition called orthostatic hypotension.
Liquid crystals are familiar to most of us as the somewhat humdrum stuff used to make computer displays and TVs. Even for scientists, it has not been easy to find other ways of using them. Now a group of researchers is putting liquid crystals to work in a completely unexpected realm: as detectors for the protein fibers implicated in the development of neuro-degenerative diseases such as Alzheimer's.
Why do babies smile when they interact with their parents? Could their smiles have a purpose? A team of computer scientists, roboticists and developmental psychologists confirm what most parents already suspect: when babies smile, they do so with a purpose -- to make the person they interact with smile in return. To verify their findings, researchers programmed a toddler-like robot to behave like the babies they studied and had the robot interact with undergraduate students.
Scientists have successfully defeated a dangerous intestinal pathogen, Clostridium difficile, with a drug targeting its toxins rather than its life. C. difficile is responsible for more than 250,000 hospitalizations and 15,000 deaths per year in the United States, costing the country more than $4 billion in health-care expenses, said the study's senior author.
Researchers used a brain-to-brain interface they developed to allow pairs of participants to play a '20 question' style game by transmitting signals from one brain to another over the Internet. Their experiment is thought to be the first to demonstrate that two brains can be directly linked to allow someone to accurately guess what is on another person's mind.
A 9,000-year-old case of human decapitation has been found in the rock shelter of Lapa do Santo in Brazil.
