A UK trial to blend 20% hydrogen with 80% methane in Keele University’s grid has shown that it’s possible to safely distribute and use hydrogen in a live grid, as well as cope with fluctuations in demand. The 18-month HyDeploy project, which delivered over 42,000m3 of hydrogen to 130 homes and faculty buildings, has already […]

The scars of past assaultslie scattered on the shore.The force of every blowetched into the earthwith the relentlessnessof your approach;ancillary depositswashed up in broken ridgesand battered covesalong the trembling coast.Combing through coresand tree trunkswe read rings like runes,searching for sedimentary survivorsin the hidden creasesof their blinkered testimonies.Fractured historiesweaved togetherto plot tendenciesfor future violence.

Scientists in Japan have identified metabolic compounds within the blood that are associated with dementia. The study revealed that the levels of 33 metabolites differed in patients with dementia, compared to elderly people with no existing health conditions. Their findings, published this week in PNAS, could one day aid diagnosis and treatment of dementia. “Metabolites are chemical […]

Wingtips of certain species of silkmoth are structured to reflect sound and throw off attackers, according to a new study. Researchers at the University of Bristol have discovered that the tips of some saturniid moth forewings are curiously rippled and folded. They found that these unique structures strongly reflect sound, meaning that a bat hunting […]

Linking the cost of prescription drugs in the United States to the prices paid in other high-income nations could have reduced American spending for the drugs by at least half in 2020, according to a new RAND Corporation study. Modeling a proposal that would cap U.S. prices at 120% of what is paid in six […]

This star-studded image from the NASA/ESA Hubble Space Telescope depicts NGC 6717, which lies more than 20,000 light-years from Earth in the constellation Sagittarius. NGC 6717 is a globular cluster, a roughly spherical collection of stars tightly bound together by gravity. Globular clusters contain more stars in their centers than their outer fringes, as this […]

Chewing gum after heart surgery may kickstart the digestive tract, helping patients feel better and potentially be discharged sooner than those who don’t use this generally safe and simple intervention, according to research presented today at the 18th Annual Perioperative and Critical Care Conference from The Society of Thoracic Surgeons. “Prior to our study, there […]

It’s an old adage: there’s no harm in getting a second opinion. But what if that second opinion could be generated by a computer, using artificial intelligence? Would it come up with better treatment recommendations than your professional proposes? A pair of Canadian mental-health researchers believe it can. In a study published in the Journal of Applied Behavior […]

Humans acknowledge that personality goes a long way, at least for our species. But scientists have been more hesitant to ascribe personality—defined as consistent behavior over time—to other animals. A study from the University of California, Davis is the first to document personality in golden-mantled ground squirrels, which are common across the western U.S. and […]

Physicians prescribed opioids more often to their white patients who complained of new-onset low back pain than to their Black, Asian and Hispanic patients during the early days of the national opioid crisis, when prescriptions for these powerful painkillers were surging but their dangers were not fully apparent, according to a UCLA study. The findings suggest […]
