More than half the people in some developing countries could become newly at risk for malnutrition if crop-pollinating animals -- like bees -- continue to decline, experts say. Despite popular reports that pollinators are crucial for human nutritional health, no scientific studies have actually tested this claim -- until now.
Targeting a key enzyme and its associated metabolic programming may lead to novel drug development to treat lung cancer, researchers report. Cancer cells undergo metabolic alterations to meet the increased energy demands that support their excess growth and survival. The Krebs cycle in the mitochondria of cells is used to supply both energy and building materials for cell growth. Two mitochondrial enzymes -- pyruvate carboxylase (PC) and glutaminase replenish carbon to the Krebs cycle.
The metabolic function of the essential enzyme laforin has been identified by researchers, which opens new pathways to treating the deadly Lafora's disease. Lafora disease occurs as a result of the laforin gene being mutated. Mutations in the gene encoding the laforin protein result in the accumulation aberrant glycogen-like accumulations called Lafora bodies that resemble plant starch more than human glycogen.
A critical molecule has been identified by a team of dental scientists that helps explain why diabetics suffer from impaired healing. Their results pinpoint a target for therapies that could help boost healing.
Most patients presenting to the emergency department with syncope or dizziness may not benefit from head CT unless they are older, have a focal neurologic deficit, or have a history of recent head trauma.
Brain scans confirm significant differences in play behavior, brain activation patterns and stress levels in children with autism spectrum disorder as compared with typically developing children, new research demonstrates.
Nearly three-quarters of homeless adults with mental illness in Canada show evidence of cognitive deficits, such as difficulties with problem solving, learning and memory, new research has found. The study-believed to be the largest of its kind -assessed neurocognitive functioning indicators such as mental processing speed, verbal learning and memory in 1,500 homeless adults in five Canadian cities.
People who use cochlear implants for profound hearing loss do respond to certain aspects of music, contrary to common beliefs and limited scientific research, says a research team. The scientists say exposure to the beat in music, such as drums, can improve the emotional and social quality-of-life of cochlear implant users and may even help improve their understanding and use of spoken language.
The inaccuracy of weather forecasts has personal implications for people around the world. New research from Tel Aviv University prioritizes, for the first time, the reasons for forecasting failures across different regions of the planet, quantifying the causes -- man-made and natural -- for weather prediction inaccuracies.
Using one of the largest supercomputers in the world, a team of researchers has identified potential materials that could improve the production of ethanol and petroleum products. The discovery could lead to major efficiencies and cost savings in these industries.
A swarm of tiny probes each with a different sensor could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere. The probes would last an estimated 15 minutes according to planetary scientists. Transmitting 20 megabits of data over 15 minutes would be sufficient to allows scientists to get a picture of a large part of the atmosphere of the planet.
Most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth's atmosphere warms. They also provide inconsistent explanations of why these wiggles occur in the first place, a new study finds. These inconsistencies may undermine the models' reliability for projecting the short-term pace and extent of future warming, and indicate that we shouldn't over-interpret recent temperature trends. The study analyzed 34 models used in the most recent IPCC assessment report.
Although nearly four in 10 workers wouldn't tell their manager if they had a mental health problem, half said that if they knew about a coworker's illness, they would desire to help, a new survey shows. The survey reveals that workers have both negative and supportive attitudes about mental health in the workplace.
On 24 January 2015, Meteosat-7 becomes the longest-serving operational satellite in EUMETSAT history, clocking up 17 years of monitoring the weather from space.
Scientists have pinned down how a dangerous tropical parasite which is transmitted by ticks manages to turn healthy cells into cancer-like invasive cells, according to research. Microscopic Theileria parasites infect the blood of mammals, particularly cattle, causing serious illness.
Infants show distinct, consistent patterns of brain activity in response to painful vaccinations, new research shows.
New details in a cellular mechanism that serves as a defense against stress have been identified by a team of biologists. The findings potentially offer insights into tumor progression and neurodegenerative diseases, such as Parkinson's and Alzheimer's -- the cell's inability to respond to stress is a major cause of these diseases.
As nanomachine design advances, researchers are moving from wondering if the nanomachine works to how long it will work -- an important question as there are so many potential applications, e.g., for medical uses including drug delivery and early diagnosis. Scientists observed a molecular shuttle powered by kinesin motor proteins and found it to degrade when operating, marking the first time degradation has been studied in detail in an active, autonomous nanomachine.
Scientists have identified a circuit in the brains of mice that regulates thirst. When a subset of cells in the circuit is switched on, mice immediately begin drinking water, even if they are fully hydrated. A second set of cells suppresses the urge to drink.
A panorama from one of the highest elevations that NASA's Mars Exploration Rover Opportunity has reached in its 11 years on Mars includes the U.S. flag at the summit.
