Swimmers who wore Speedo’s controversial LZR Racer suit at the 2008 Beijing Olympics broke 23 world records, proving that being more streamlined has advantages. A new study out of Japan has shown that the same theory applies to sperm.

Scientists have developed a new method of providing information on 3D-printed foods, by printing a QR code within the food itself. Doing so doesn't affect the taste or outward appearance of the food, nor does it require the use of any labels.

Type 1 diabetes can be a rare but serious side effect of a cancer treatment that use what are known as immune checkpoint inhibitors. In a new study in mice, researchers in Japan have shown that administering stem cell therapy could help prevent this.

Australian nuclear fusion company HB11 says its disruptive laser-powered reactor design has demonstrated results "many orders of magnitude higher than those reported by any other fusion company," without requiring multi-million degree temperatures.

Scientists are reporting successful preclinical tests of a nasal spray designed to prevent the neurodegeneration associated with dementia. The spray combines two cheap drugs and was found to improve cognitive function in several mouse models of dementia.

The world of lab-grown meats is fast filling with all kinds of tasty bites, from burgers, to chicken breasts, to a series of increasingly complex cuts of steak. Now, Japan's famous Wagyu beef joins the list.

Metolazone, an anti-hypertension drug, has been found to kickstart a lifespan-extending cellular repair process in roundworms. The mechanism may be translatable to humans, offering new research pathways in the search for an anti-aging drug.

In order to observe specific behaviors, scientists will often rig wild animals up with tiny cameras or other "bio-logging" devices. A new technology could help these tools gather more data, by only fully powering up when needed.

Ordinarily, when using an off-the-shelf 3D printer, it's quite difficult to print a single object that incorporates multiple materials. An experimental new system could make it easier, though, by utilizing a "programmable filament."

Whether it's entangling marine animals or forming giant floating "garbage patches," oceanic plastic waste is a huge problem. There may be new hope however, in the form of what is claimed to be a better type of marine-biodegradable plastic.

In what is a world-first and potentially the dawn of a new medical technology to treat damaged hearts, scientists in Japan have succeeded in transplanting lab-grown heart cells into human patients for the first time ever.

We've already seen tactile-feedback displays that convey information by applying tiny vibrations to the user's fingertips. An experimental new technology takes a different approach, however – it gets sticky in select areas.
