Direct sound printing uses ultrasound to create microscopic oscillating bubbles, which in turn cause resin to solidify at specific locations

3D Printing

New type of 3D printing uses sound waves to build up objects

3D printing typically involves depositing layers of molten plastic, laser-melting powdered metal, or using UV light to harden gelatinous resin. A new technique takes yet another approach, however, by utilizing sound waves.

A new study suggests that avoiding high-intensity workouts within two hours of bedtime is best for a sound night's sleep

Intense workouts shortly before bed found to impact sleep quality

It is well known that a physically active day can make for a better night's rest, but a new study has delved into how the timing of our workouts matters and suggests steering clear of late-night sessions if you want to feel rejuvenated in the morning.

Knowing a second language has been shown to build regions of the brain that typically atrophy in Alzheimer's patients

Being bilingual might help save your brain

Researchers have analyzed brain scans from both multilingual and monolingual people, all of whom were previously diagnosed with either Alzheimer's disease or mild cognitive impairment (MCI). Their conclusion: knowing a second language may help offset the effects of degenerative brain disorders.

A sea lamprey shows off its sucker-like rasping mouth

Scientists tell lampreys to scram

If you've spent much time around the Great Lakes, then you're probably familiar with the sea lamprey. It's a destructive invasive species, which depletes stocks of native fish by feeding on their blood. Thanks to recent research, however, there may be new hope for controlling lamprey populations.

The team developed a technique that uses small recording devices to collect data, which is then run through mathematical models to pinpoint leaks

"Noise loggers" save water by listening for leaks

In the average distribution system, as much as 30 percent of treated water is lost due to leaks, but the problems can be hard to pinpoint. Now, researchers have developed a technique that could have a big impact on the problem, using “noise logger” devices to spot underground leaks.
