Early-life exposure to traffic-related air pollution was significantly associated with higher hyperactivity scores at age 7, according to new research from the University of Cincinnati (UC) and Cincinnati Children's Hospital Medical Center.
It is the first time scientists have decoded the genome of a plant pathogen and its plant host from dried herbarium samples. This opens up a new area of research to understand how pathogens evolve and how human activity impacts the spread of plant disease.
The epigenetic modifications, which alter the way genes function without changing the underlying DNA sequence, can apparently be detected in the blood of pregnant women during any trimester, potentially providing a simple way to foretell depression in the weeks after giving birth, and an opportunity to intervene before symptoms become debilitating.
Herds of wooly mammoths once shook the earth beneath their feet, sending humans scurrying across the landscape of prehistoric Ohio. But then something much larger shook the Earth itself, and at that point these mega mammals' days were numbered.
The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical current as they are threaded through a nanoscopic hole.
New research from the University of Southampton has shown that blind and visually impaired people have the potential to use echolocation, similar to that used by bats and dolphins, to determine the location of an object.
Waterproof fabrics that whisk away sweat could be the latest application of microfluidic technology developed by bioengineers at the University of California, Davis.
Meeting the demand for more data storage in smaller volumes means using materials made up of ever-smaller magnets, or nanomagnets. One promising material for a potential new generation of recording media is an alloy of iron and platinum with an ordered crystal structure. Researchers led by Professor Kai Liu and graduate student Dustin Gilbert at the University of California, Davis, have now found
Individuals who learn two languages at an early age seem to switch back and forth between separate "sound systems" for each language, according to new research conducted at the University of Arizona.
Earthquakes that last minutes rather than seconds are a relatively recent discovery, according to an international team of seismologists. Researchers have been aware of these slow earthquakes, only for the past five to 10 years because of new tools and new observations, but these tools may explain the triggering of some normal earthquakes and could help in earthquake prediction.
The Amazon rain forest, popularly known as the lungs of the planet, inhales carbon dioxide as it exudes oxygen. Plants use carbon dioxide from the air to grow parts that eventually fall to the ground to decompose or get washed away by the region's plentiful rainfall.
Imagine a bendable tablet computer or an electronic newspaper that could fold to fit in a pocket.
A new study conducted at the University of Bristol and published online today in the Journal of Evolutionary Biology sheds light on how the brain and inner ear developed in dinosaurs.
Researchers have pinpointed a catalytic trigger for the onset of Alzheimer's disease – when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain.
As weather warms up off the coast of France, blooms of plankton have once again begun to form, creating a beautiful, multicolored swirl visible from space.NASA's Terra and Aqua satellites acquired these images of the colorful blooms on April 20 and May 4, according to the NASA Earth Observatory. On the later date, a noticeably larger bloom occurred, fueled by nutrient ru...
A largely forgettable rainfall provoked a growth in vegetation that, followed by a hot, near-record dry period, simply resulted in more fuel for potential wildfires.When it comes to Southern California's increasingly perilous fire season, you can blame both the lack of rain and the little rain we did have.
The appeal of owning your own property — and all the private goods that came with it — may have convinced nomadic humans to settle down and take up farming. So says a new study that tried to puzzle out why early farmers bothered with agriculture.
Douglas Trumbull's new project would use fast frame rates, huge screens, 4K digital for an "immersive" experience. Are audiences ready?
Chris Hadfield has conquered space. Now he's conquering the Internet, too.
Neuroscientist Henry Markram says he can build a supercomputer replica of the human brain. Now he has $1.3 billion to prove it.
Hospitals hoping to attract patients and build goodwill are teaming up with medical-screening companies to promote tests they say might prevent deadly strokes or heart disease. What their promotions don’t say is that an influential government panel recommends against many of the tests for people without symptoms or risk factors.
I detest household bugs. Abhor them. There isn’t a word strong enough to describe how I feel about bugs in my home. That hatred provokes guilt, because I fancy myself an environmentalist. As such, I’m supposed to feel a kinship with all creatures. We’re connected in a circle of life, a colorful tapestry, a delicate web of interdependence.
Bodily waste is widely considered a topic not to be discussed in polite company; it’s something to be flushed and forgotten. But a new book argues that waste, in all its human and animal forms, is worth getting to know intimately
Bacteria that live in the gut have been used to reverse obesity and Type-2 diabetes, animal studies show.
Vast reserves of shale oil is set to make the US an exporter rather than a leading importer, delivering a blow to Middle East oil producers that can expect to see demand fall, an International Energy Agency report observes.
The Sun has unleashed the most powerful eruption - a solar flare - of 2013 so far.
If Mercury was an orange, the juicy bit would all be dense metallic core, while planets further out would be peaches with pit-like cores – here's why
Big data might one day allow us to project how conflicts will develop, but choosing whether and how to intervene will always be difficult
New findings about the properties of fossil amber could shed light on glass and glass-like materials.
