Tech Xplore / Employing low-frequency noise can help electric vehicles stand out in busy environments
One of the many benefits of electric vehicles is that they are much quieter than traditional gasoline-powered vehicles. In some cases, though, they are too quiet. Automakers are required to design their vehicles so they emit ...
Phys.org / Death and devastation: Why a rare equatorial cyclone and other storms have hit southern Asia so hard
More than 900 people are dead, thousands more missing and millions affected by a band of cyclones and extreme monsoonal weather across southern Asia. Torrential rain has triggered the worst flooding in decades, accompanied ...
Phys.org / Sugar-coated sensor sniffs out look-alike molecules in the air
Scientists have designed a new type of gas sensor that can tell apart "mirror image" versions of the same smell molecule, even at very low concentrations. By coating carbon nanotubes with custom-built sugar-based receptors, ...
Medical Xpress / Compounded imiquimod ointment may be beneficial for some ocular surface cancers
Compounded imiquimod 5% ointment may be safe and effective for diffuse conjunctival melanoma in situ (MIS) or ocular surface squamous neoplasia (OSSN), according to a case series study published online Nov. 26 in JAMA Ophthalmology.
Phys.org / Factory farming in Africa: Development banks see it as a good idea, but it's bad for the climate
In sub-Saharan Africa, pastoral livestock farming—where cattle, goats and sheep roam freely across grasslands, grazing at will—has been the main form of livestock production. It has been a source of livelihoods for centuries, ...
Phys.org / Funding agencies can end profit-first science publishing
Funding organizations can fix the science publishing system—which currently puts profit first and science second—according to research published on the arXiv preprint server.
Medical Xpress / Telehealth boomed during COVID, but in some areas, its promise fell short
While telehealth use surged during the COVID-19 pandemic, some U.S. counties struggled to use resources efficiently, revealing widespread misallocation of health care infrastructure, workforce and technology, according to ...
Phys.org / Mineral fertilizer, not soil, found to supply most toxic cadmium in wheat grains
Plants absorb not only nutrients but also toxic metals such as cadmium through their roots. It was previously unclear whether the toxic metals came from the soil or the fertilizers applied. Under the leadership of the Helmholtz ...
Medical Xpress / Antifungal resistance is making thrush hard to treat. Here's why
Thrush is one of the most common infections in the world. It's caused by the fungi Candida—specifically, the yeast Candida albicans. Although yeast infections are normally treated easily with antifungal drugs, a growing ...
