Participation in a prevention program known as the Strong African American Families Program, which enhances supportive parenting and strengthens family relationships, removes the effects of poverty on brain development, research demonstrates for the first time.
In a remote area of north-central Tanzania, men leave their huts on foot, armed with bows and poison-tipped arrows, to hunt for their next meal. Dinner could come in the form of a small bird, a towering giraffe or something in between. Meanwhile, women gather tubers, berries and other fruits. The Hadza live a very different kind of lifestyle -- and a very active one, engaging in significantly more physical activity than what is recommended by U.S. government standards. They also have extremely low risk of cardiovascular disease.
The island of Madagascar off the coast of Africa was largely unexplored seismically until recently. The first broadband seismic images of the island help solve a longstanding mystery: why are there volcanoes far from any tectonic boundary?
Incentives that are designed to enable smarter use of the ocean while also protecting marine ecosystems can and do work, and offer significant hope to help address the multiple environmental threats facing the world’s oceans, researchers conclude in a new analysis.
Venezuelan equine encephalitis virus (VEEV) is an unforgiving killer of horses, donkeys and zebras, resulting in mortality as high as 80 percent of infected animals. It causes rapid, catastrophic swelling of the brain and spinal cord, leading to severe neurological symptoms and—in many cases—sudden death. The virus can also infect humans, with similar results. Now a research team has exploited a weakness in VEEV's genetic code, resulting in a far less deadly mutant version of the virus when tested in laboratory mice.
Wildlife ecologists who study the effects of climate change assume, with support from several studies, that warming temperatures caused by climate change are forcing animals to move either northward or upslope on mountainsides to stay within their natural climate conditions. But a new study of lowland and higher-mountain bird species now shows an unexpected and "unprecedented" inconsistency in such shifts.
A smart patch has been designed to monitor a patient’s blood and release blood-thinning drugs as needed to prevent the occurrence of dangerous blood clots – a condition known as thrombosis. In an animal model, the patch was shown to be more effective at preventing thrombosis than traditional methods of drug delivery.
Under the right conditions, 2 1/2-year-old children can answer questions about people acting on false beliefs, an ability that most researchers believe does not develop until age 4, new research demonstrates.
Disruptions in the Hedgehog signaling pathway can interfere with taste bud maintenance in mice, potentially explaining why some cancer patients experience a loss of taste during treatment with Hedgehog-blocking drugs, researchers have found.
Some people claim to experience pain just watching something painful to happen. This is true especially of people suffering from complex regional pain syndrome (CRPS), a disabling chronic pain disorder in a limb. In CPRS patients, both own movements and just observing other persons’ movements may aggravate the pain.
A breakthrough advance has been made by trapping an intermediate in the mechanism of enzymes called heme peroxidases and determining its structure using a beam of neutrons from the heart of a nuclear reactor.
Researchers have created sOPTiKO, a more efficient and controllable CRISPR genome editing platform. In a new article, they describe how the freely available single-step system works in every cell in the body and at every stage of development. This new approach will aid researchers in developmental biology, tissue regeneration and cancer.
Graphene is currently one of the most extensively studied materials in the world, both on a scientific and industrial level. The world’s first two-dimensional material, this single layer of carbon atoms arranged in a hexagonal lattice has a series of unique and outstanding properties. As well as being the thinnest, strongest and lightest known material, graphene is flexible, impermeable and extremely electrically and thermally conductive. All properties well suited for next generation NFC antennas.
An international group of plant biologists has succeeded for the first time in visualizing how egg cells in plants divides unequally (asymmetric cell division) after being fertilized. The direction of this asymmetric cell division determines the body axis of flowering plants, i.e. the top part producing leaves and flowers, and the bottom part developing into roots. This mechanistic discovery on asymmetric cell division in plants provides insight into finding out how flowering plants have evolved to form their body shape.
Approximately one third of people with Alzheimer’s disease use prescription medicines for pain after their diagnosis, reports a recent study. The use of analgesics was as common among persons with Alzheimer’s disease as it was among those of the same age without the disease, but there were significant differences in the types of medicines used.
Fairness is a central concept in the adult world. But how do children learn what is fair and what is not? When do children learn to distribute resources in an equitable manner, and what do they do when it is impossible to divide the pie equally?
Disruptions of daily rhythms of the body's master internal clock cause depression- and anxiety-like behaviors in mice, reports a new study. The findings provide insight into the role of the brain's internal time keeping system in the development of mood disorders, such as bipolar disorder and major depressive disorder, which have been associated with disturbed daily (circadian) rhythms.
In science news around the world, a new containment structure slides into place over a Chernobyl Nuclear Power Plant reactor, scientists in Argentina brace for budget cuts in 2017, a new report finds that harm reduction strategies for illegal drug injectors are underused, a U.K. parliamentary committee warns that the government needs to ensure that research is at the center of Brexit negotiations, and the U.S. Surgeon General calls for accelerating research on alcohol and drug addiction. Also, Science discusses censorship research with computer scientist Phillipa Gill of the University of Massachusetts in Amherst. And a new interactive visualization tool lets users monitor air pollution around the planet in real time.
