Help With Stuttering Could Come From Electricity

At the University of Oxford, [Jen Chesters] conducts therapy sessions with thirty men in a randomized clinical trial to test the effects of tDCS on subjects who stutter. Men are approximately four times as likely to stutter and the sex variability of the phenomenon is not being tested. In the randomized sessions, the men and [Jen] are unaware if any current is being applied, or a decoy buzzer is used.

Transcranial Direct Current, tDCS, applies a small current to the brain with the intent of exciting or biasing the region below the electrode. A credit-card sized card is used to …read more

Jerri Nielsen: Surviving the Last Place on Earth

There may be no place on Earth less visited by humans than the South Pole. Despite a permanent research base with buildings clustered about the pole and active scientific programs, comparatively few people have made the arduous journey there. From October to February, up to 200 people may be stationed at the Amundsen-Scott South Pole Station for the Antarctic summer, and tourists checking an item off their bucket lists come and go. But by March, when the sun dips below the horizon for the next six months, almost everyone has cleared out, except for a couple of dozen “winter-overs” who …read more

The Physics of Healing: Radiation Therapy

Few days are worse than a day when you hear the words, “I’m sorry, you have cancer.” Fear of the unknown, fear of pain, and fear of death all attend the moment when you learn the news, and nothing can prepare you for the shock of learning that your body has betrayed you. It can be difficult to know there’s something growing inside you that shouldn’t be there, and the urge to get it out can be overwhelming.

Sometimes there are surgical options, other times not. But eradicating the tumor is not always the job of a surgeon. Up to …read more

Delivery Drone Aims To Make Package Handoffs Safer Than Ever

Picture this: you’re at home and you hear a rapping on your door. At last!– your parcel has arrived. You open the door, snatch a drone out of the air, fold it up, remove your package, unfold it and set it down only for it to take off on its merry way. Hand-delivery courier drones might be just over the horizon.

Designed in the [Laboratory of Intelligent Systems] at Switzerland’s École Polytechnique Fédérale de Lausanne and funded by [NCCR Robotics], this delivery drone comes equipped with its own collapsible carbon fibre shield — it fold up small enough to fit …read more

Using A Thermal Camera To Spot A Broken Wrist

Chemist and Biochemist [Thunderf00t] has shown us a really interesting video in which you can spot the wrist he broke 10 years ago using a thermal camera.

He was on an exercise bike while filming himself on a high-resolution thermal camera, As his body started to heat up he noticed that one hand was not dumping as much heat as the other. In fact one was dumping very little heat. Being a man of science he knew there must be some explanation for this. He eventually came to the conclusion that during a nasty wrist breaking incident about 10 years …read more

Hackaday Prize Entry: Heart Failure Detection Device

Early and low-cost detection of a Heart Failure is the proposal of [Jean Pierre Le Rouzic] for his entry for the 2017 Hackaday Prize. His device is based on a low-cost Doppler device, like those fetal Doppler devices used to listen an unborn baby heart, feeding a machine learning algorithm that could differentiate between a healthy and an unhealthy heart.

The theory behind it is that a regular, healthy heart tissue has a different acoustic impedance than degenerated tissue. Based on the acoustic impedance, the device would classify the tissue as: normal, degenerated, granulated or fibrous. Each category indicates specific …read more
