Scientists have developed a ground-breaking piezoelectric-based DC-DC converter that unifies all power switches onto a single chip to increase power density. This new power topology, which extends beyond existing topologies, blends the advantages of piezoelectric converters with capacitive-based DC-DC converters.
Scientists unveil metasurface technology, allowing for angle-dependent holograms.
Findings more than a decade in the making reveal a rich diversity of beneficial fungi living in boreal forest trees, with implications for the health of forests.
The drug finasteride, also known as Propecia or Proscar, treats male pattern baldness and enlarged prostate in millions of men worldwide. But a new study suggests the drug may also provide a surprising and life-saving benefit: lowering cholesterol and cutting the overall risk of cardiovascular disease.
Using a single photograph, researchers created an algorithm that computes highly accurate, full-color three-dimensional reconstructions of areas behind obstacles -- a concept that can not only help prevent car crashes, but help law enforcement experts in hostage situations, search-and-rescue and strategic military efforts.
AstroSat is India’s first multi-wavelength space observatory launched in 2015
A new study reveals that passive video use among toddlers can negatively affect language development, but their caregiver's motivations for exposing them to digital media could also lessen the impact.
Deep-water corals in the Gulf of Mexico are still struggling to recover from the devastating Deepwater Horizon oil spill in 2010, scientists report at the Ocean Science Meeting in New Orleans. Comparing images of more than 300 corals over 13 years -- the longest time series of deep-sea corals to date -- reveals that in some areas, coral health continues to decline to this day.
A team of scientists on location with a film crew in the remote Amazon has uncovered a previously undocumented species of giant anaconda.
A collaborative project has made a breakthrough in enhancing the speed and resolution of wide-field quantum sensing, leading to new opportunities in scientific research and practical applications.
Researchers have mapped out the proteins implicated in the early stages of motor neurone disease (MND). They have developed a longitudinal map of the proteins involved in MND across the trajectory of the disease, identifying potential therapeutic pathways for further investigation.
A pharmacy associate professor has developed a novel nanomedicine loaded with genetic material called small interfering RNAs (siRNA) to fight human immunodeficiency virus (HIV) using gene therapy.
A team of researchers has found a potential way to treat conditions like depression and anxiety with fewer side effects.
Researchers have created an artificial cell environment that could promote the regeneration of nerves. Usually, injuries to the brain or spinal cord don't heal easily due to the formation of fluid-filled cavities and scars that prevent tissue regeneration. One starting point for medical research is therefore to fill the cavities with a substance that offers neural stem cells optimal conditions for proliferation and differentiation.
Common pool resources comprise around 65 percent of Earth's surface and vast tracts of the ocean. While examples of successful governance of these resources exist, the circumstances and mechanisms behind their development have remained unclear. Researchers have developed a simulation model to examine the emergence, stability and temporal dynamics of collective property rights.
Biomolecules such as amino acids and sugars occur in two mirror-image forms -- in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.
For many genetic diseases, disabling or editing a gene using CRISPR is insufficient to overcome the effects of the underlying genetic mutation. A corrective gene needs to be added to the genome to fix the problem. Researchers have discovered a way to use a bird retrotransposon -- a type of junk DNA -- to insert whole transgenes into the human genome in a targeted way that does not risk damaging other genes.
Cycles of a diet that mimics fasting can reduce signs of immune system aging, as well as insulin resistance and liver fat in humans, resulting in a lower biological age, according to a new study.
Researchers have developed a multipronged strategy to identify the transporters used by different drugs. Their approach, which makes use of both tissue models and machine-learning algorithms, has already revealed that a commonly prescribed antibiotic and a blood-thinner can interfere with each other.
Physicists have used complex computer simulations to develop a new design for significantly more efficient solar cells than previously available. A thin layer of organic material, known as tetracene, is responsible for the increase in efficiency.
