Feed aggregator
Contrary to popular belief, the benefits of physical activity do not outweigh the risks of cardiovascular disease associated with drinking sugar-sweetened beverages, according to a new study.
Surprise discovery of tiny insect-killing worm
Scientists have discovered a tiny worm species that infects and kills insects. These worms, called nematodes, could control crop pests in warm, humid places where other beneficial nematodes are currently unable to thrive.
Are environmental toxins putting future generations at risk?
In a study that signals potential reproductive and health complications in humans, now and for future generations, researchers have concluded that fathers exposed to environmental toxins, notably DDT, may produce sperm with health consequences for their children.
How fruit flies control the brain's 'steering wheel'
A newly discovered neural circuit mediates between navigational brain cells, acting as a sort of mental steering wheel.
Pregnant women should avoid ultraprocessed, fast foods, experts urge
Research shows that phthalates, a class of chemicals associated with plastics, can shed from the wrapping, packaging and even from plastic gloves worn by food handlers into food. Once consumed during pregnancy, the chemicals can get into the bloodstream, through the placenta and then into the fetal bloodstream. The chemical can cause oxidative stress and an inflammatory cascade within the fetus, researchers noted. Previous literature has indicated that exposure to phthalates during pregnancy can increase the risk of low birth weight, preterm birth and child mental health conditions such as autism and ADHD.
Africa could grow more rice -- new study shows how
African demand for rice is projected to more than double during the next 25 years because of population growth and increased rice consumption. A research project shows that the average yield for Africa's rice sector represents less than half the yield that could be achieved with improved agronomic practices. That means African farmers have the ability to significantly increase crop production without tilling more land.
'Legacy' phosphorus delays water quality improvements in Gulf of Mexico
The same phosphorus that fertilizes the thriving agriculture of the Midwest is also responsible for a vast 'dead zone' in the Gulf of Mexico near the Mississippi Delta. Efforts to reduce the amount of phosphorus that enters the Mississippi River system are underway, but research suggests that remnants of the contaminant are left behind in riverbeds for years after introduction and pose an overlooked -- and lingering -- problem.
Ancient rocks improve understanding of tectonic activity between earthquakes
Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.
Friend or foe? Ancient partnership between moss and fungi
Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.
Psychology study unearths ways to bolster global climate awareness and climate action
An international team of scientists has created a tool that can aid in increasing climate awareness and climate action globally by highlighting messaging themes shown to be effective through experimental research.
Scientists reveal why blueberries are blue
Tiny external structures in the wax coating of blueberries give them their blue color, researchers reveal.
Researchers discover new cell that remembers allergies
Researchers have made a groundbreaking discovery: a new cell that remembers allergies.
What turned Earth into a giant snowball 700m years ago? Scientists now have an answer
Inspired during field work in South Australia's Flinders Ranges, geoscientists have proposed that all-time low volcanic carbon dioxide emissions triggered a 57 million year-long global 'Sturtian' ice age.
Replacing animal-based foods with alternative proteins would unlock land for carbon removal
Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.
Green doesn't always mean clean: Cleaning products urgently need better regulation, researchers warn
Researchers say there needs to be better regulation and more guidance for consumers about how safe cleaning products really are.
New research uncovers biological drivers of heart disease risk
Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.
Illustrating the relationship between pedestrian movement and urban characteristics using large-scale GPS data
Researchers developed the pedestrian movement index to capture pedestrian count, distance walked, and time spent in metro station areas using large-scale Global Positioning System data. This index elucidates the relationship between pedestrian behavior and various urban-space elements (such as density, diversity, design, accessibility, and distance).
EVs that go 1,000 km on a single charge: Gel makes it possible
Engineers apply electron beam technology to develop an integrated silicon-gel electrolyte system.
Organic compound found in trees could prevent contact lens eye infections
Researchers say hydroquinine could be an effective naturally occurring disinfecting solution for contact lenses and help combat keratitis infections.
Dinosaurs' success helped by specialized stance and gait, study finds
Dinosaurs' range of locomotion made them incredibly adaptable, researchers have found.
