Asthma inhaler prototype is nearly as slim as a credit card

Asthma inhaler prototype is nearly as slim as a credit card

Asthma inhalers have largely had the same design for a very long time, and for good reason: they're relatively lightweight and small, and can be slipped into a pocket. Still, they're highly conspicuous and no one likes to pull them out in public for an impromptu puff; as well, having to carry it around is burdensome if it is reserved for the rare occasional asthma attack rather than daily use. That's where this new ultra-slim inhaler prototype comes in.

Mind-controlled prosthetic arm can wiggle its fingers

Mind-controlled prosthetic arm can wiggle its fingers

Prosthetic research has progressed rapidly over the past few years, with researchers demonstrating increasingly fine and complex control, in some cases using direct brain connects to facilitate the movements. The industry has just unveiled yet another milestone, with John Hopkins researchers successfully demonstrating individual prosthetic finger movements performed via mind control.

3D bioprinter used to print a transplantable human ear

3D bioprinter used to print a transplantable human ear

Scientists have developed a new 3D bioprinter that has been successfully used to print a replacement human ear that could be transplanted to a patient in need. A human ear isn't all that the scientists have used the 3D printer to create, so far the team has created part of a jawbone, muscle, and cartilage structures in addition to the ear. The team is led by Anthony Atala from the Wake Forest Institute for Regenerative Medicine and the printer is the result of almost a decade of work.

New polymer can retain shape changes, resets with body heat

New polymer can retain shape changes, resets with body heat

A team of University of Rochester researchers have developed a new polymer that may play a big part in the medical field in the future. The material is able to maintain a new shape after being stretched or manipulated, something in itself that isn't new, but the incredible part is that it then can be returned to its original shape with just body heat. The researchers say that's only half of their discovery, however, as during shape recovery the polymer is able to release a large amount of stored energy.

DARPA: ‘stentrode’ implant travels to brain via blood vessels

DARPA: ‘stentrode’ implant travels to brain via blood vessels

Under DARPA’s Reliable Neural-Interface Technology program, a team from the University of Melbourne has created a new device called a ‘stentrode’ that, when implanted near one’s brain, is able to read signals from neurons. The work was done as part of a DARPA project, and it is said to be safer than implants requiring brain surgery. The device is about the size of a paperclip, according to the researchers, and it is implanted through a blood vessel.

FDA guides makers on securing connected medical devices

FDA guides makers on securing connected medical devices

The FDA has released a draft guidance for companies that make connected medical devices, advising them of steps that should be taken to deal with cybersecurity risks. The guidance concerns medical devices that connect to a facility’s network, and comes at a time when an increasing number of companies — medical and otherwise — have been hit with massive data breaches.

This donkey has a prosthetic leg and her name is Bella Burro

This donkey has a prosthetic leg and her name is Bella Burro

A donkey in Minnesota is living the good life thanks to a prosthetic leg made specifically for her. Her name is Bella Burro, and if it weren't for a couple in Minneapolis, she'd be dead. Totally dead. But she's alive, and she's got her own Facebook page, and it's all thank to both that couple of folks and the fine people at Arise Orthotics. As of this article's posting, Bella is 2 years and 5 months old, and fabulous as ever.

Dissolving sensor can be used to measure intracranial pressure

Dissolving sensor can be used to measure intracranial pressure

A team of researchers from the University of Illinois led by professor John Rogers has designed an implantable sensor that can be injected into the brain to monitor intracranial pressure and temperature for about five days. That is the length of time where the pressure and temperature inside the head need to be monitored after some sort of traumatic brain injury.

Myo armband used to control prosthetic arm

Myo armband used to control prosthetic arm

Researchers around the world are working to make prosthetic limbs more lifelike to give people who have lost arms or legs the ability to have a more normal life. Researchers have recently used Myo armbands to allow a prosthetic wearer to control a robotic prosthetic arm wirelessly.

Myo gesture control band controls MPL prosthetic arm

Myo gesture control band controls MPL prosthetic arm

The Modular Prosthetic Limb has suddenly become a lot more versatile as the Johns Hopkins Applied Physics Laboratory-developed prosthetic works with the Myo armband. The Myo armband is a gesture-control accessory that allows people to control all manner of devices and software as it senses movements in their arm*. Muscles expand and contract and the armband sends signals wirelessly to other devices. In this case, it means that the armbands are able to give this MPL arm movement.

MC10 “BioStamp” connects to your body, shares data

MC10 “BioStamp” connects to your body, shares data

Amid waves of wearables at CES 2016, MC10 have revealed the BioStamp Research Connect System. This system works with a sort of soft stamp, or sticker, that sticks to your body and shares physiological data with computers. These flexible body-worn sensors allow the wearer to operate entirely normally as they bend and move with the body, rather than hindering it. This system reduces observation error at the same time as it improves data capture, so says MC10.

E-cigarette liquid ingredient can cause ‘popcorn lung’ disease

E-cigarette liquid ingredient can cause ‘popcorn lung’ disease

A new Harvard study has found that many e-cigarette liquids contain an ingredient linked to ‘popcorn lung,’ a serious lung disease that got its name after popcorn plant workers developed the disease from exposure to artificial butter fumes. The chemical in question is diacetyl, and Harvard researchers found that more than 75-percent of the liquids and ecigs they tested contained the ingredient.
