Bacteria that were thought to be resistant to a powerful antibiotic may be susceptible to treatment after all, research has found.
The food-poisoning bug Listeria was shown to respond to an antibiotic even though the bacteria carry genes that should make it highly resistant.
Scientists say the antibiotic—called fosfomycin—should be reconsidered as a treatment for life-threatening Listeria infections.

The free market Adam Smith Institute says we could be on the cusp of a revolution.
When I wrote that 41% of land in the contiguous United States is used to feed livestock, I thought it was a pretty high number. According to a new report from the free market-leaning Adam Smith Institute, however, the UK has us beat on that front:
Apparently a full 85% of the UK’s land footprint is associated with animal product production.
It’s the year 2038. The word “flavor” has fallen into disuse. Sugar is the new cigarettes, and we have managed to replace salt with healthy plants. We live in a society in which we eat fruit grown using genetics. We drink synthetic wine, scramble eggs that do not come from chickens, grill meat that was not taken from animals, and roast fish that never saw the sea… Here’s a futurist outlook at the next two decades of food developments, from robot farmers to 3D-printed meals to AI monitoring of your daily calorie intake.
Sometimes science simply confirms what we already know to be true. You know what I’m talking about: researchers will find evidence that losing sleep makes you cranky and bad at your job, that eating lots of vegetables is good for your gut, or that Uranus is surrounded by a noxious fart cloud.
Indeed, the new findings on the latter published in Nature Astronomy come as no surprise to those who’ve spent time closely examining Uranus. More than a year ago, planetary scientists told Gizmodo’s Ryan F. Mandelbaum that the essence of this ice giant’s scent would probably be dominated by ammonia and hydrogen sulfide. Hydrogen sulfide gives rotten eggs their stink, but it’s also associated with the odor of a human fart.
Still, scientists had never directly detected the presence of these stinky molecules. Until now, that is. The authors of the new study examined sunlight bouncing off Uranus as captured by the 8-meter Gemini North telescope in Hawaii. Scientists determined what sorts of molecules were inside the atmosphere by examining the light it reflected in infrared. Different compounds absorb and cast off different wavelengths of light—creating a distinct and identifiable signature if you know what to look for. Think of it as dusting for fingerprints, but instead of a suspect, you’re looking for molecular compounds. The group says they were just barely able to detect the signatures they sought; it took a telescope as sensitive as Gemini and conditions as clear and perfect as those found at its home on Mauna Kea. Even though no one has ever smelt it, scientists can now say with certainty which molecules have dealt it.
A far better approach, then, is the middle course. Rather than prejudge the products of biotechnology, regulators should screen new plants and single out those that might need special monitoring or restrictions. In the U.S., the Food and Drug Administration does something similar on a voluntary basis for foods made from plants with engineered proteins. Companies submit data about their new products, and if the FDA decides it has no further questions, they can claim their foods are “generally recognized as safe.”
Europe and the U.S. should avoid an all-or-nothing approach to regulating plants made with Crispr.
Speedy, affordable water tests that can be used in on location and even run continuously will help scientists identify disease-causing bacteria in under an hour and potentially reduce the spread of common illnesses such as diarrhoea, which kills an estimated 842,000 people every year.
Hundreds of millions of samples are tested each year to detect harmful bacteria in drinking and environmental water, food and beverages, but tests can take days or, in some cases, even weeks to provide definitive results. By then, many people may have fallen ill from diseases caused by bacteria such as E. coli or legionella.
Shrinking the laboratory to the size of a home printer – and bringing down test times to an hour or less – could help to stop outbreaks in their tracks and keep people safe.
In 2018, what is left to explore in the world? It seems unlikely, say, that humans might find an untouched forest to study, someplace that hasn’t been bulldozed and burnt and exploited within an inch of its life for precious minerals or virgin timber. But that’s exactly what happened this past spring, when a Welsh researcher, Dr. Julian Bayliss, led a 28-person team that included scientists specially selected for their different talents as well as logistics experts, rock climbers, and filmmakers to the top of a mountain in Mozambique.
The story of the Mount Lico expedition began six years ago when Bayliss, a conservation scientist and butterfly expert, happened to spy a small forest atop a mountain using Google Earth. It wasn’t the first time he’d found such a place; Bayliss had been using Google Earth to explore high-altitude rainforests in Africa for around 15 years. In February 2017, the time was finally right: Bayliss brought a drone to the base of the 410-foot sheer rock protuberance (technically known as an inselberg) to confirm that there was a forest on top. This was no small feat. The area surrounding Mount Lico is a patchwork of smallholder farms, tea and eucalyptus plantations, and woodlands. There are no paved roads, no hotels — just rivers to cross, plants to hack away with machetes, and miles of dirt track to navigate.
While locals were aware of Mount Lico and used the natural resources of surrounding forests, its tall, sheer walls meant that it was nearly impossible to access, which made it likely that the land on top was untouched by humans. However, scientists would later find out that someone had been up there at least once.
Seed oil components of an ornamental flower could provide a direct pathway for designing a new class of environmentally friendly lubricants. Researchers at the School of Science at IUPUI identified the compound in the seed oil that is produced in a manner unlike any other fatty acid. The study was published today online in the journal Nature Plants.
The Orychophragmus violaceus plant is a purple flower native to China; it’s commonly referred to as the February orchid. While collaborating on the O. violaceus plant’s biology and genetic makeup, researchers at Huazhong Agricultural University in Wuhan, China, and the University of Nebraska-Lincoln encountered a bit of a mystery: All plant seeds contain oils as energy reserves for later growth, but researchers noticed the February orchid seed oils were unusual.
They called upon IUPUI bioorganic chemist Robert Minto, who specializes in identifying natural products and unknown compounds.
