Someday, Doctors May Test Circulation With Blood-Boiling Sonic Blasts

Currently, doctors use ultrasound to measure blood flow in the body. Doppler effect, just like bats! But it can’t detect flow in the small, slow-moving vessels where diseases often start. The solution? Sonic blasts that heat up a tiny drop of blood, then watch where it goes. Science! While this might sound like a comic…

This 3D Gesture-Detecting Chip Could Actually Make Smartwatches Useful

If idea of fiddling around with a tiny, wrist-mounted touchscreen is enough to make you want to give up on smartwatches before they even really arrive, then whoa. This 3D gesture-recognition might actually make these things useful. Researchers at the University of California at Berkeley and Davis are developing a tiny chip which uses ultrasound…

Watch These Water Drops Levitate and Form Spinning, Pulsating Stars

If you play around with an ultrasound field for long enough, you can set up standing waves that allow you to levitate water drops in mid-air—but that’s only where the fun starts. The drops, held in a node of low pressure and supported in mid-air by a high-pressure zone sat beneath them, can be excited…

Hawkmoths use their genitals to scare off bats

Bats hunt moths and other insects by using echolocation, where they emit ultrasonic calls and analyze the rebounding sound. So to avoid getting eaten by hungry bats, hawkmoths blast the flying mammals with their own ultrasound…which comes from their genitals. Seriously. Bats and insects have engaged in an evolutionary arms race lasting nearly 65 million…

Amazing and Adorable: 4D Scan Shows a Fetus Yawning in the Womb

Medical imaging’s come a long way in the past few decades—but it’s now so good that doctors can use it to tell the difference between a baby opening its mouth and it yawning. A team of researchers from Durham University, UK, has been analyzing data from 4D ultrasound scans which create three dimensional renderings of…

Scottish Scientists Invent “Sonic Screwdriver”

Part Tricorder and part lock-pick, Dr. Who’s famous all-in-one device could handle any crisis—save deadlock seals. Now, researchers from Dundee University have replicated at least some of the screwdriver’s functionality with a machine capable of lifting and turning suspended objects. The Dundee device is able to raise and turn disks suspended in a water-filled tube.…

Ultrasound Treatment Cures Prostate Cancer Perfectly Nine Times in Ten

A new treatment, using highly focused ultrasound, effectively kills cancerous prostate tumors nine times out of ten. What’s more, the technique produces virtually no side effects and means patients only have to spend a single evening in hospital. Prostate cancer is a massive killer, but existing treatments—such as conventional surgery or radiotherapy—often leave patients with…

Hear the ultrasonic scream of this pint-sized primate!

At just five inches long, tarsiers are among the world’s smallest primates. And yet they communicate much like humans, using a wide range of calls to communicate. That’s why it’s so weird that some tarsiers apparently stay completely silent. Tarsiers are like living fossils — a tiny link back to the ancient beginnings of primate…
