Many potential pharmaceuticals end up failing during clinical trials, but thanks to new research, biological molecules once considered for cancer treatment are now being repurposed as organic semiconductors for use in chemical sensors and transistors.
Read moreResearchers have made a discovery that could provide new insights into how superconductors might move energy more efficiently to power homes, industries and vehicles. Their work showed that graphene — a material composed of a single layer of carbon atoms — is more likely to become a superconductor than originally thought possible.
Read moreSeagrass meadows put down deep roots, persisting in the same spot for hundreds and possibly thousands of years, a new study shows. Researchers used modern and fossil shells from seagrass-dwelling animals to estimate the age of these meadows, showing that, far from being transient patches of underwater weeds, they are remarkably stable over time.
Read moreA research team has developed methods to manipulate polymers in a way that changes their fundamental structure, paving the way for potential applications in cargo delivery and release, recyclable materials, shape-shifting soft robots, antimicrobials and more.
Read moreA nuclear war between India and Pakistan could, over the span of less than a week, kill 50-125 million people — more than the death toll during all six years of World War II, according to new research.
Read moreAs the Earth's temperature warms, its hydrological cycle kicks into overdrive – wet years get wetter, and dry years get drier. According to a new study, these increased rainfall extremes could have dire consequences for the semi-arid forests of the western U.S.
Read moreMicroliths are often interpreted as being part of composite tools, including projectile weapons, essential to efficient Homo sapiens hunting strategies. In Europe and Africa, these lithic toolkits are linked to hunting medium and large-sized animals in grassland or woodland settings, or as adaptations during periods of climatic change. The presence of microliths in Sri Lanka suggests the existence of more diverse ecological contexts for these technologies by some of the earliest members of our species.
Read moreScientists have now succeeded in using high-resolution imaging to make visible to the millisecond how the HI virus spreads between living cells and which molecules it requires for this purpose. The researchers provide direct proof for the first time that the AIDS pathogen creates a certain lipid environment for replication.
Read moreA non-invasive approach could help marine biologists monitor coral health in the face of climate change.
Read moreCorals exude chemical defenses against bacteria, but when heated in the lab, those defenses lost much potency against a pathogen common in coral bleaching. There's hope: A key coral's defense was heartier when that coral was taken from an area where fishing was banned and plenty of fish were left to eat away seaweed that was overgrowing corals elsewhere.
