Humans Age Faster at 2 Sharp Peaks, Study Finds

Getting older might seem like a slow, gradual process – but research suggests that this is not always the case.

In fact, if you wake up one morning, look in the mirror, and wonder if your aging somehow accelerated, you might not be imagining things.

According to a 2024 study into the molecular changes associated with aging, humans experience two abrupt lurches forward, one at the average age of 44 and the other at around age 60.

Harvard researchers develop novel 3D printing method for soft robotics — rotational multi-material method creates muscle-like structures that can be programmed to twist, lift, or bend

Elon Musk reveals his most ambitious (and detailed) plan for Mars: 1,000 spacecraft, 20 years of launches, and a self-sustaining city of one million inhabitants on Mars by 2050

At the entrance to Starbase in south Texas, a glowing sign now welcomes visitors with the words “Gateway to Mars.” The display sits in front of SpaceX facilities where giant Starship rockets are being assembled with one bold purpose in mind: Elon Musk wants to build a self-sustaining city on Mars.

In recent years he has begun to put numbers on that dream. Musk has repeatedly said that building the first sustainable city on Mars would require around 1,000 Starship rockets and roughly 20 years of launch campaigns, moving up to 100,000 people per favorable Earth-Mars alignment and eventually reaching about one million settlers plus millions of tons of cargo.

It sounds like science fiction with a project plan. Yet the language he uses, “sustainable city,” is very familiar to climate and energy experts here on Earth. So what does sustainability really mean on a frozen, air-thin world and how does that huge effort interact with the environmental crisis on our own planet?

20-Year Mystery Solved: Scientists Discover an Entirely New Way Cells Transport Bile Acids

A long-standing mystery in bile acid biology has been solved. Bile acids are often introduced as digestion helpers, but they are also powerful chemical messengers that help coordinate metabolism throughout the body. To do their jobs, these cholesterol-derived molecules must be shuttled efficiently

Brain inspired machines are better at math than expected

Neuromorphic computers modeled after the human brain can now solve the complex equations behind physics simulations — something once thought possible only with energy-hungry supercomputers. The breakthrough could lead to powerful, low-energy supercomputers while revealing new secrets about how our brains process information.
