We are all familiar with the image of electrons zipping around an atom's nucleus and forming chemical bonds in molecules and materials. But what is less known is that electrons have an additional unique property: spin. It is difficult to make an analogy, but one could crudely describe electron spin as a spinning-top rotating around its axis. But what is even more interesting is that, when spins of electrons align together in a material, this leads to the well-known phenomenon of magnetism.
PELLSTON--In an aspen-dominated hardwood forest at the northern tip of the state's Lower Peninsula, University of Michigan scientists are testing ways to make the region's forests more resilient to climate change.
About 12,000 mature trees--mostly aspen--are being cut on 77 acres at the U-M Biological Station, a 10,000-acre research and teaching facility just south of the Mackinac Bridge, near the town of Pellston.
A nationwide phase II clinical trial, coordinated out of Tufts Medical Center in Boston, has found that a topical cream was extremely effective in reversing the effects of vitiligo, a relatively common autoimmune disease that causes loss of skin pigmentation. Topical application of the medicated cream, ruxolitinib, which is currently used as an oral treatment for certain blood disorders, resulted in substantial improvement of facial vitiligo symptoms in nearly half of the trial's participants.
Physicists from the Immanuel Kant Baltic Federal University conduct a study on nanomaterials that have been synthesized by the method of the electric explosion. Research group of the Laboratory of Novel Magnetic Materials has studied the magnetic and structural properties of metallic α-Fe magnetic nanoparticles, which were covered with non-magnetic iron oxide.
AMES, Iowa - New research may explain why an antioxidant that protects the brain is also associated with deterioration in areas susceptible to Alzheimer's disease.
Earlier research has shown that growing up on a farm with animals may as much as half the risk of asthma and allergies. The protective effect is thought to be attributable to the diverse microbial exposures encountered on farms.
A new study shows that the complement system, part of the innate immune system, plays a protective role to slow retinal degeneration in a mouse model of retinitis pigmentosa, an inherited eye disease. This surprising discovery contradicts previous studies of other eye diseases suggesting that the complement system worsens retinal degeneration. The research was performed by scientists at the National Eye Institute (NEI), part of the National Institutes of Health, and appears in the Journal of Experimental Medicine.
A recent study published in the peer-reviewed journal PeerJ - the Journal of Life and Environmental Sciences highlights the fact that the economic benefits of commodity export for primate habitat countries has been limited relative to the extreme environmental costs of pollution, habitat degradation, loss of biodiversity, continued food insecurity and the threat of emerging diseases.
BINGHAMTON, N.Y. -- Citizens from the island of Aneityum in the Republic of Vanuatu are working with faculty from Binghamton University, State University of New York to test their true value as humans.
Strategies to cope with body heat in sports is a pressing issue. The Tokyo Olympics will be held in the hot and muggy Japanese summer where the ambient temperature is expected to be above 33°C. Athletes have to worry about performing under pressure of the high-stakes competition but also now have to deal with a very hot and humid climate. The 2022 FIFA World Cup in Qatar will also have high temperatures and athletes must use cooling strategies during the competition.
DGIST research team succeeded in developing stem cell delivery of scaffold1 microrobot that can precisely deliver cells to a target body tissue. This research achievement is expected to enhance the treatment safety and efficiency of degenerative neural disorders as it can precisely transplant the exact amount of stem cell-based treatment cells to human body tissues and organs.
A recent study revealed that by decorating iron nanocubes with gold the functionality of nanoparticles can be increased.
One of the major challenges in nanotechnology is the precise control of shape, size and elemental composition of every single nanoparticle. Physical methods are able to produce homogeneous nanoparticles free of surface contamination. However, they offer limited opportunity to control the shape and specific composition of the nanoobjects when they are being built up.
A hair-sized probe that can measure key indicators of tissue damage deep in the lung has been developed by scientists.
The new technology could pave the way for accurate monitoring of tissue in areas where existing technologies cannot reach.
Experts say the probe can pick up tiny changes in tissue health and could improve how patients are assessed and treated, specifically those on ventilators in intensive care.
Having a child with a developmental disorder can cause parents to worry about the outcome of further pregnancies. In cases where the genetic mutation causing the disorder is not present in either parent it is assumed to be a one-off event with a very small chance of recurrence. But in some families, the risk of having another affected child is as high as 50%. Identifying such high-risk families and providing an accurate assessment of their chances of having a unaffected child is therefore a high priority for clinical geneticists.
"Power shift" needed to improve gender balance in energy research, report says
Women still face significant barriers in forging successful and influential careers in UK energy research, a new high-level report has revealed.
