This 3D-printed wearable mosquito repellent could finally end re-applying sprays

The study is in the early phase but promising.

We use body sprays to get rid of mosquitos most of the time. We can even use herbs such as sage and rosemary to keep them out of our homes. Martin Luther University Halle-Wittenberg scientists have created a novel method of delivering insect repellent (MLU). The results were published in the.

The researchers used “IR3535,” an insect repellent created by MERCK, to create their prototypes.

Auroras are responsible for punching holes in the ozone layer

A type of aurora briefly tore a 400 km wide hole in Earth’s ozone layer.

An international team of researchers showed that a certain type of aurora called the “Isolated proton aurora” depletes our atmosphere’s ozone layer. They discovered a nearly 250-mile-wide (400 kilometers) hole in the ozone layer right above where an aurora occurred. Before now, the influence of these particles was only vaguely known. The study is published in Scientific reports.

What causes the auroras?

Solar storms on the sun’s surface give out huge clouds of electrically charged particles. These particles can travel millions of miles, and some may eventually collide with the Earth. Most of these particles are deflected away, but some become captured in the Earth’s magnetic field. When they are entrapped, their charge ionizes the atmosphere and produces nitrogen oxides and hydrogen oxides. Both compounds contribute to ozone loss.

Researchers looked deep inside the brain to see how memory is stored

This is the first study to record such electrical activity from inside the brain.

How do people remember the things they’ve learned? To get to the bottom of the mystery, scientists undertook a study that looked deep inside the brain.

Neuroscientists from Northwestern University and clinicians from the University of Chicago Epilepsy Center examined the electrical activity in the brains of five patients at the center in response to sounds administered by the research team as part of a learning exercise.

To get to the bottom of the mystery, scientists undertook a study that looked deep inside the brain, where “previous learning was reactivated during sleep,” resulting in a refined memory.

Video: An engineer produces a torch-like prosthetic for his lost eye

He turned a crisis into an opportunity.

Brian Stanley is a living human cyborg. He has gone viral after sharing a video on social media with an eye flashlight that can light up the whole room. After losing one eye to cancer.

As Brian Stanley suggested in the video, the eye has a battery life of roughly 20 hours, and “it does not get hot.”

FDA gives clearance to Philips for its AI powered MRI scans

The artificial intelligence software speeds up the process of taking scans.

Philips received clearance from the FDA for its artificial intelligence MR platform that is used to detect cancerous tumors in the head and neck.

FDA clearance for AI technology

The company announced that the FDA gave clearance for Philip’s AI-enabled MRCAT radiotherapy. The clearance, also known as the 510(k) clearance, requires device manufacturers to register, and notify FDA of their intent to market a medical device at least 90 days in advance.

Rats with backpacks will be the savior of earthquake survivors

They’re tiny but have a knack for saving human life.

The Belgian non-profit organization APOPO trains rats to help earthquake survivors. Called RescueRATs, these rats are preparing to save those under the earthquake debris with their high-tech backpacks on their backs.

As CNN reported, “Rats are typically quite curious and like to explore — and that is key for search and rescue,” says Donna Kean, a behavioral research scientist and leader of the project. She also adds that they train rats because they have a good sense of smell and can easily fit into small spaces.

How are the rats trained?

SpaceX shares an image of Falcon Heavy’s 27 Merlin engines ahead of launch

The world’s most powerful operational rocket could finally launch again as soon as next week.

SpaceX’s Falcon Heavy, the most powerful rocket in the world, is approaching its first launch in over three years. The massive launch system, which is powered by three modified Falcon 9 first-stage boosters, is now linked together and awaiting launch from Pad 39A at NASA’s Kennedy Space Center.

Ahead of the launch, SpaceX has shared an image of the behemoth’s 27 Merlin engines on Twitter. “Falcon Heavy in the hangar at Launch Complex 39A,” the company wrote alongside the impressive photo.
