Scientists have used gene-editing advances to achieve a tenfold increase in the production of super-bug targeting formicamycin antibiotics.

Organizations seeking to fill internal roles traditionally have two options: promote from within or hire externally. Internal promotions benefit from being vetted talent who possess firm-specific skills while outside hires harbor external knowledge that can infuse an organization with new energy. Though this dichotomy is often accepted as unavoidable, there is a third option: boomerang employees.

Photosynthesis, the process by which plants and other organisms convert sunlight into chemical energy, has been a major player during the evolution of life and our planet's atmosphere. Although most of the ins and outs of photosynthesis are understood, how the necessary mechanisms evolved is still a topic of debate. The answer to this question, however, may actually lie buried in the mineral world.

How dark is the sky, and what does that tell us about the number of galaxies in the visible universe? Astronomers can estimate the total number of galaxies by counting everything visible in a Hubble deep field and then multiplying them by the total area of the sky. But other galaxies are too faint and distant to directly detect. Yet while we can't count them, their light suffuses space with a feeble glow.

As the rover has continued to ascend Mount Sharp, it's found distinctive benchlike rock formations.

María Martinón-Torres and José María Bermúdez de Castro, researchers at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have participated in a study published in the Journal of Human Evolution, on one of the few human fossils known from late Early Pleistocene China, the Meipu teeth, which provides new information on the early settlement of continental Asia.

Current means of fighting bacteria are no longer as good as they used to be because of antibiotic resistance. These days, people are dying from bacterial infections that could have been cured fifty years ago.

Most consumers of drinking water in the United States know that chemicals are used in the treatment processes to ensure the water is safe to drink. But they might not know that the use of some of these chemicals, such as chlorine, can also lead to the formation of unregulated toxic byproducts.

Insufficient interactions with advisers and peers, as well as financial problems, are derailing career aspirations of women and minority groups pursing graduate degrees in the nation's highest-funded chemistry programs.

Research on cycad trees in Colombia, Guam, and the Philippines has illuminated how knowledge of their branching behavior may benefit conservation decisions for the endangered plants. In a study published in the December issue of the journal Horticulturae, scientists from the University of Guam and the Montgomery Botanical Center in Florida show that the number of times a cycad tree produces a branch can be used to infer the sex of the tree. The findings have practical applications for use of the sexual dimorphism that is described.

There's an expanded nationwide recall of Sportmix pet food products underway, after links were found between a mold-borne toxin in the food and the deaths of 70 dogs, with 80 other dogs being sickened, the U.S. Food and Drug Administration announced Monday.

Every field has its underlying principles. For economics it's the rational actor; biology has the theory of evolution; modern geology rests on the bedrock of plate tectonics.

Researchers have developed a new laser-based process for 3-D printing intricate parts made of glass. With further development, the new method could be useful for making complex optics for vision, imaging, illumination or laser-based applications.

A team of researchers at Columbia University has developed a way to allow DNA strands to store more data. In their study, published in the journal Science, the group applied a small amount of electricity to DNA strands to allow for encoding more information than was possible with other methods.

While many research teams worldwide are trying to develop highly performing quantum computers, some are working on tools to control the flow of heat inside of them. Just like conventional computers, in fact, quantum computers can heat up significantly as they are operating, which can ultimately damage both the devices and their surroundings.

An international team of astronomers reports the discovery of a new exoplanet as part of the Next Generation Transit Survey (NGTS). The newly found alien world, designated NGTS-14Ab, is about 30% larger than Neptune. The finding was detailed in a paper published January 5 on arXiv.org.
