By combining brain scans and nutritional intake data, a study has found a nutrient profile that puts the brakes on brain aging. What's more, that profile matches an easy-to-follow popular eating plan that's been proven to convey multiple benefits.

We now know just how the earliest land plants, ancient algae, conquered terrestrial Earth hundreds of millions of years ago and laid the (literal) groundwork for all subsequent life. It highlights the fascinating genetic strategies of plant evolution.

Unusually high levels of lead and uranium has been found in the urine of teenagers who frequently use e-cigarettes. But experts have warned that, due to research flaws, not enough has been done to ensure the link isn't just smoke and mirrors.

Six doctors in Nebraska have successfully operated a surgical robot aboard the ISS. This time, the operation was on only rubber bands, but the milestone could have meaning for future missions to Mars or for rural operating rooms here on Earth.

Among the cargo that just blasted off from Cape Canaveral, Florida, bound for the ISS were two firsts: the world’s first metal 3D printer designed especially for use in orbit and the first miniaturized surgical robot to be sent to the station.

Name a type of organic matter and chances are some type of organism has evolved to eat it. Plants, meat, algae, insects and bacteria are all consumed by different creatures, but now scientists have discovered something new on the menu – viruses.

Although plain popcorn is a relatively healthy snack, it's still not one that most people would think of as being very nutritious. That could change, however, as a new variety reportedly offers nearly twice the normal levels of an important nutrient.

One shortcoming of carbon fiber that scientists have been working to address is its tendency to burn at high temperatures, and an international team of researchers have now found a low-cost and scalable solution to this problem.

The treatment of chronic wounds often involves the application of different medications, at different stages in the healing process. A new electronic bandage could allow this to happen, but without having to be removed for each application.

Over the last few years, perovskite has proven itself to be a promising material for photovoltaic solar cells, but it’s not without its problems. Now, a team has found a way to helps solve at least one of those issues, removing toxic lead from the device by substituting in titanium.

Aluminum is nice and light, but that comes at the cost of strength. By introducing faults into the metal’s crystalline structure, researchers at Purdue University have now developed new aluminum alloys that are about as strong as stainless steel, and they could make for corrosion-resistant coatings.

​Imagine if a bandage could release fresh doses of medication over time, or even different types of medication at specific times. Well, researchers from the University of Nebraska-Lincoln, Harvard Medical School and MIT have developed just such a thing … and it could be controlled by a smartphone.
