The 2024 QS World University Rankings were released this week, and with three new key metrics added to the scoring process, several universities have rocketed to the international forefront, while traditional icons are being pushed below the fold.

Americans aged 25-65 years are dying at far higher rates than their peers from other high-income countries, even surpassing death rates in Central and Eastern Europe. A new study examines what's caused the three-decade rise in midlife mortality.

For anyone who thinks that all electric boats are really just aquatic golf carts, well … think again. A Princeton University student team recently broke a world speed record for electric-powered boats, with an average speed of 114.2 mph (183.8 km/h).

Although lithium can be found in hard mineral ores, it's more often extracted from very salty (aka briny) groundwater. The latter task could soon be much quicker and eco-friendlier, thanks to a new string-based extraction technique.

Although we've seen a number of systems that use sunlight to purify tainted water, their output is often quite limited. A new loofah-inspired hydrogel, however, uses sunlight to treat much more water in one go … enough to meet a person's daily needs.

If a robot is going to be tiny, then it better have a way of getting around the many obstacles that will block its way. A new type of robot takes a unique approach to doing so, by jumping like a click beetle.

As microplastics pollution and potable water scarcity both worsen, it's becoming increasingly important to find efficient ways of filtering and desalinating seawater. A new aerogel definitely holds some promise, and it's made from egg whites.

Before perovskite can become viable for solar cells, it needs to overcome a major durability issue. Engineers at Princeton have unveiled a new perovskite solar cell design that tests suggest could last as long as 30 years of real-world use.

Scientists regularly turn to nature for inspiration in their pursuit of next-generation materials, and engineers studying the porous microstructures of bone and wood have come up with a clever example of biomimicry with wide-ranging potential.

Evidence shows fasting diets can enhance cancer treatment and a new mouse study has found adding a keto diet to chemotherapy tripled survival time compared to chemotherapy alone. A human clinical trial testing the combination treatment is now underway.

Impressive new research has shown how a common diabetes drug can be inactivated by bacterial enzymes produced in the oral and gut microbiome. The researchers speculate this process may explain why the drug is not effective in some diabetic patients.

Princeton and the University of Washington researchers have developed a camera the size of a grain of salt that can snap sharp, full-color images. It’s made with a metasurface that captures light and could be scaled up to turn entire surfaces into sensors.
