From renting your tree, to sponsoring a turkey, a growing number of people are having a greener Christmas.
Reductions in air pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, according to new findings.
Victoria city council has an ambitious climate target, and it's asking the cruise industry to get on board. The harbour authority is looking into installing shore power and also cutting back on emissions from land transportation, once passengers...
Land speed record holder Andy Green describes his final high-speed test run in the Bloodhound car.
A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium.
Using a clever technique that causes unruly crystals of iron selenide to snap into alignment, physicists have drawn a road map that reveals the quantum ''rules of the road'' that electrons must follow in the enigmatic superconductor.
Women who have C-sections are no more likely to have children who develop obesity than women who give birth naturally, according to a large study. The findings contradict several smaller studies that did find an association between C-section deliveries and offspring obesity but did not consider the numerous maternal and prenatal factors that the researchers did in this study.
Johns Hopkins engineers have created a new lens-free ultra-miniaturized endoscope, the size of a few human hairs in width, that is less bulky and can produce higher quality images.
Scientists report they have created a tiny, nanosize container that can slip inside cells and deliver protein-based medicines and gene therapies of any size -- even hefty ones attached to the gene-editing tool called CRISPR.
Gel-like materials have a wide range of applications, especially in chemistry and medicine. However, their usefulness is sometimes limited by their inherent random and disordered nature. Researchers have found a way to produce a new kind of gel which overcomes this limitation. It is still malleable and adaptable like existing gels, but it has a more ordered structure, which can open up a new range...
A physicist has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser.
Life has changed a lot for the environmental activist in the space of a year.
Using a clever technique that causes unruly crystals of iron selenide to snap into alignment, Rice University physicists have drawn a detailed map that reveals the "rules of the road" for electrons both in normal conditions and in the critical moments just before the material transforms into a superconductor.
Mode of delivery unrelated to whether a baby is overweight as a young adult, study suggestsDelivery by caesarean section does not increase the chance of a baby ending up overweight or obese as a young adult, researchers have found, contrary to previous research.The authors of the study say their work drew on a huge number of people and more fully takes into account a wide range of possible factors...
Scientists at Johns Hopkins Medicine report they have created a tiny, nanosize container that can slip inside cells and deliver protein-based medicines and gene therapies of any size—even hefty ones attached to the gene-editing tool called CRISPR. If their creation—constructed of a biodegradable polymer—passes more laboratory testing, it could offer a way to efficiently ferry larger medical...
Gel-like materials have a wide range of applications, especially in chemistry and medicine. However, their usefulness is sometimes limited by their inherent random and disordered nature. Researchers from the University of Tokyo's Institute for Solid State Physics have found a way to produce a new kind of gel which overcomes this limitation. It is still malleable and adaptable like existing gels,...
The Philippines' north has been hit by some of its worst flooding in decades, with torrents of muddy runoff forcing 66,000 from their homes and prompting rescues of trapped locals, authorities said Friday.
Researchers at Florida International University have found coating seeds with a fungus and a bacterium could help valuable crops block the one-two punch of saltier groundwater and soil.
A controversial pesticide linked to developmental problems in humans will be definitively banned in the EU in 2020 after a vote on Friday by member states, the European Commission said.
Biologists at Texas A&M University are making strides in understanding biological clock function in several model organisms and translating these studies into broader implications for human health.
Chocolate-producing cacao trees that are resistant to a major pathogen were identified by an international team of plant geneticists. The findings point the way for plant breeders to develop trees that are tolerant of the disease.
When a plant senses an invading pathogen, it activates a molecular signaling cascade that switch on its defense mechanisms. One such mechanism involves sacrificing host cells to the pathogen. This is a tightly controlled process that involves the work of plant proteins to ensure that the sacrificial cells are only killed if the pathogen is attacking. This process, called the cell death response,...
By monitoring crops through machine learning and satellite data, scientists have found farms that till the soil less can increase yields of corn and soybeans and improve the health of the soil -- a win-win for meeting growing food needs worldwide.
Physicists have designed an experiment to explain the concept of magnetic resonance. A versatile technique employed in chemistry, physics, and materials research, magnetic resonance describes a resonant excitation of electron or atomic nuclei spins residing in a magnetic field by means of electromagnetic waves.
