A new type of phase-change concrete could completely revolutionize how we handle icy conditions. That’s because the new concrete is capable of melting ice and snow, removing the need to use salt or shoveling. Scientists have created a new self-heating material that could heavily reduce the amount of plowing and salting needed to keep roadways safe. As it stands, more than 70% of roads are within snowy regions, the US Department of Transportation (DOT) claims. As such, there are many times throughout the year…

In preparation for a permanent human colony on the Moon, DARPA has awarded a contract to Northrop Grumman to develop a lunar railway concept, as part of the 10-year Lunar Architecture (LunA-10) Capability Study.Running a train on the Moon may seem profoundly silly, but there is some very firm logic behind it. Even as the first astronauts were landing on the Sea of Tranquility in 1969, it was realized that a permanent human presence on Mars would require an infrastructure to maintain it. That includes mines for water ice,…

Intermittent fasting is being touted for a range of short-term benefits revealed in recent studies, but we don't know much about its long-term effects. A new study has found some concerning links that may outweigh the benefits of intermittent fasting in the long run. One form of this popular dietary intervention, known as time-restricted eating (TRE), has dieters restricting their food intake to within a window of just eight hours or less in a day, and fasting for the remaining 16 hours or more. While some people…

X owner Elon Musk recently described using small amounts of ketamine "once every other week" to manage the "chemical tides" that cause his depression. He says it's helpful to get out of a "negative frame of mind". This has caused a range of reactions in the media, including on X (formerly Twitter), from strong support for Musk's choice of treatment, to allegations he has a drug problem. But what exactly is ketamine? And what is its role in the treatment of depression? It was first used as an anestheticKetamine is a…

Scientists in the US claim to have boiled down some of the health benefits of exercise into a swallowable pill.The novel drug is in the very early stages of development, but in initial experiments on rodents, the medicine appears to tap into a natural metabolic pathway usually triggered by exercise. When administered to mice daily, the drug, called SLU-PP-332, seems to improve muscle function, fitness, and endurance – all without the animals having to move more than they're used to. Presenting the latest results at the…

Recent research presented at the American Heart Association’s 2024 sessions found that individuals adhering to an 8-hour time-restricted eating plan had a significantly higher risk of cardiovascular mortality compared to those eating over longer periods.Research Highlights:A study of over 20,000 adults found that those who followed an 8-hour time-restricted eating schedule, a type of intermittent fasting, had a 91% higher risk of death from cardiovascular disease.People with heart disease or cancer also had an increased…

In recent years, broccoli has gained a reputation as an excellent vegetable due to its high levels of a particularly beneficial compound called sulforaphane.With some early-stage studies showing how this compound plays a role in blood sugar control and potentially even has anti-cancer benefits, it's no wonder that broccoli pills are on the rise. However, a 2011 study showed that eating the whole vegetable gets you more sulforaphane than taking a supplement – so a team of Chinese researchers decided to try and find the…

MIT economists analyzed the “winner’s curse” in job-training and housing voucher programs, introducing analytical tools to improve policy evaluation accuracy. Their work highlights the complexities of replicating initial successes and underscores the importance of sound evidence in decision-making.

An MIT economist’s tools can help planners recognize this trap.Back in the 1980s, researchers tested a job-training…
