Astronomers have found wildly misaligned planet-forming gas discs around the two young stars in the binary system HK Tauri. These new observations provide the clearest picture ever of protoplanetary discs in a double star. The new result also helps to explain why so many exoplanets — unlike the planets in the Solar System — came to have strange, eccentric or inclined orbits.
Companies who make their money in the 'sin' industries such as the tobacco, alcohol and gaming industries typically receive less attention from institutional investors and financial analysts. But new research shows social norms and attitudes towards these types of businesses are subject to compromise when their share price looks to be on the rise.
Exotic pests, shrinking ranges and a changing climate threaten some of the world's most rare and ecologically important plants, and so conservationists establish seed collections to save the seeds in banks or botanical gardens in hopes of preserving some genetic diversity. For decades, these seed collections have been guided by simple models that offer a one-size-fits-all approach for how many seeds to gather. A new study, however, has found that more careful tailoring of seed collections to specific species and situations is critical to preserving plant diversity.
Researchers have, for the first time, conducted a study under real conditions on the body clocks of members of an international polar research station. The researchers have shown that a particular kind of artificial light is capable of ensuring that their biological rhythms are correctly synchronized despite the absence of sunlight.
Printing whole new organs for transplants sounds like something out of a sci-fi movie, but the real-life budding technology could one day make actual kidneys, livers, hearts and other organs for patients who desperately need them. In the ACS journal Langmuir, scientists are reporting new understanding about the dynamics of 3-D bioprinting that takes them a step closer to realizing their goal of making working tissues and organs on-demand.
Sir David Attenborough narrates and appears in a video about the digital curation of a 20-million-year-old amber collection at the Illinois Natural History Survey at Illinois. Scientists are searching through a massive collection of 20-million-year-old amber found in the Dominican Republic more than 50 years ago, and the effort is yielding fresh insights into ancient tropical insects and the world they inhabited.
Benjamin Hause has joined the Kansas State Veterinary Diagnostic Laboratory as a research assistant professor. Hause uses next-generation sequencing and other new methods to rapidly identify pathogens. He calls himself the bug hunter, but the target of his work consists of viruses that can only be found and identified with special methods and instruments. Benjamin Hause, an assistant research professor at the Kansas State Veterinary Diagnostic Laboratory at Kansas State University, recently published an article about one of his discoveries, porcine enterovirus G, which is an important find in the United States.
Fifteen years ago, MIT professor John Essigmann and colleagues from the University of Washington had a novel idea for an HIV drug. They thought if they could induce the virus to mutate uncontrollably, they could force it to weaken and eventually die out — a strategy that our immune system uses against many viruses.
Wild tomato species are not edible, but they can be bred with domestic tomatoes to introduce new traits such as flavor and drought resistance. A new genome sequence for wild... The genome of Solanum pennellii, a wild relative of the domestic tomato, has been published by an international group of researchers including the labs headed by Professors Neelima Sinha and Julin Maloof at the UC Davis Department of Plant Biology. The new genome information may help breeders produce tastier, more stress-tolerant tomatoes.
