1.   Study Finds Electric Vehicles Provide Lower Carbon Emissions Through Additional Channels

19 Dec 2021

A recent study found that the total indirect emissions from electric vehicles pale in comparison to the indirect emissions from fossil fuel-powered vehicles. This is in addition to the direct emissions from combusting fossil fuels — either at the tailpipe for conventional vehicles or at the power plant smokestack for electricity generation — showing electric vehicles have a clear advantage emissions-wise over conventional vehicles.


2.   Computer Attacks with Laser Light

Computer systems that are physically isolated from the outside world (air-gapped) can still be attacked. This is demonstrated by IT security experts of KIT in the LaserShark project. They show that data can be transmitted to light-emitting diodes of regular office devices using a directed laser.


3.   Artificial Intelligence Accurately Detects Fractures on X-rays, Alerts Human Readers

A new study has found that artificial intelligence (AI) can help physicians in interpreting x-rays after an injury and suspected fracture. The AI algorithm (AI BoneView), was trained on a very large number of X-rays from multiple institutions to detect fractures of the limbs, pelvis, torso and lumbar spine, and rib cage.


4.   Face Detection in Untrained Deep Neural Networks​

Researchers have found that higher visual cognitive functions can arise spontaneously in untrained neural networks. A research team has shown that visual selectivity of facial images can arise even in completely untrained deep neural networks.


5.   Mind-Controlled Robots Now One Step Closer

Two EPFL research groups teamed up to develop a machine-learning program that can be connected to a human brain and used to command a robot. The program adjusts the robot’s movements based on electrical signals from the brain. The hope is that with this invention, tetraplegic patients will be able to carry out more day-to-day activities on their own.

6.   ‘Pop-up’ Electronic Sensors Could Detect When Individual Heart Cells Misbehave

23 Dec 2021

Engineers have developed a powerful new tool that monitors the electrical activity inside heart cells, using tiny “pop-up” sensors that poke into cells without damaging them. The device directly measures the movement and speed of electrical signals traveling within a single heart cell—a first—as well as between multiple heart cells. It is also the first to measure these signals inside the cells of 3D tissues.
