The nascent field of nanotechnology-enabled metallurgy has great potential. However, the role of eutectic alloys and the nature of alloy solidification in this field are still largely unknown. To demonstrate one of the promises of liquid metals in the field, we explore a model system of catalytically active Bi-Sn nano-alloys produced using a liquid-phase ultrasonication technique and investigate their phase separation, surface oxidation, and nucleation.

Microplastics are increasingly found in drinking water, but there is no evidence so far that this poses a risk to humans, according to a new assessment by the World Health Organization.

Breaking the sub–2-h marathon in an official event has attracted growing interest in recent times with commercial and international momentum building.http://www.indiaenvironmentportal.org.in/c

Efforts to make heritable changes to the human genome are fraught with uncertainty. Here’s what it would take to make the technique safe and acceptable.

Rhino- and enteroviruses are important human pathogens, against which no antivirals are available. The best-studied inhibitors are “capsid binders” that fit in a hydrophobic pocket of the viral capsid.

Nectar robbing – foraging nectar illegitimately – has negative, neutral, or positive efects on maternal function of plant reproduction and/or on pollinators.

There is evidence that pathogenic bacteria can adapt to antiseptics upon repeated exposure. More alarming is the concomitant increase in antibiotic resistance that has been described for some pathogens. Unfortunately, efects of adaptation and cross-adaptation are hardly known for oral pathogens, which are very frequently exposed to antiseptics.

The assignment of a symbolic representation to a specific numerosity is a fundamental requirement for humans solving complex mathematical calculations used in diverse applications such as algebra, accounting, physics and everyday commerce. Here we show that honeybees are able to learn to match a sign to a numerosity, or a numerosity

Although the unifying hallmark of prion diseases is CNS neurodegeneration caused by conformational corruption of host prion protein (PrP) to its infective counterpart, contagious transmission of chronic wasting disease (CWD) results from shedding of prions produced at high titers in the periphery of diseased cervids. While deer and elk

The search for a bioactive natural antibacterial agent with wound healing properties is a common practice for the development of new-generation molecules.
