Astronomers get a rare glimpse of the exposed core of a star

Posted by in categories: chemistry, physics, space

Sometimes astrophysics gets super weird.


A recent study of the star’s surface, published in the journal Nature Astronomy, says that we’re seeing Gamma Columbae in a short, deeply weird phase of a very eventful stellar life, one that lets astronomers look directly into the star’s exposed heart.

What’s New – The mix of chemical elements on the surface of Gamma Columbae look like the byproducts of nuclear reactions that should be buried in the depths of a massive star, not bubbling on its surface.

China’s newly released drone is reportedly exact replica of MQ-28 Ghost Bat

Posted by in category: drones

The FH-97A closely resembles the MQ-28 Ghost Bat.

The China Aerospace Science and Technology Corporation (CASC) has unveiled a model of an FH-97A that is almost a direct replica of the Airpower Teaming System loyal wingman drone.

A newly found loophole enables researchers to see through walls

Posted by in categories: drones, internet

The Wi-Peep uses many messages to communicate with a target device while it is in the air.

A research team from the University of Waterloo created a drone-powered tool that uses WiFi networks to penetrate barriers.

Called Wi-Peep, the device can fly close to buildings and then use the WiFi network of the occupants to identify and locate any WiFi-enabled devices quickly.

Scientists create edible drone built of rice cakes and gelatin that can save lives

Posted by in categories: drones, food, robotics/AI

The size of the wing, made of compressed puffed rice, depends on the recipient’s nutrition requirements.

The IEEE/RSJ International Conference on Intelligent Robots and Systems in Kyoto last week saw an ingenious creation presented by researchers from the Swiss Federal Institute of Technology Lausanne. Their paper described a drone made from rice cakes.

Mind you, this was no light matter. Titled ‘Towards Edible Drones for Rescue Missions: Design and Flight of Nutritional Wings,’ by Bokeon Kwak, Jun Shintake, Lu Zhang, and Dario Floreano from EPFL, the paper detailed a drone that could “boost its payload of food from 30 percent to 50 percent of its mass”, according to a release.

Future humans may have abnormalities from using technology too much

Posted by in category: futurism

Excessive technology use could cause future humans to form a second eyelid and alterations in the hands and back.

Advancements in technology change how people work and function, often speeding up the process or creating efficiency. However, there is a possibility that technology is affecting our bodies, especially from using it often.

A research project commissioned by TollFreeForwarding warns that using technology too much could form abnormalities. Researchers collaborated with a 3D designer to make images of a “future human” that shows tech-related problems from daily technological use. Researchers named the 3D model “Mindy”.

Musk’s hyperloop site will be transformed into a parking lot- here’s why

Posted by in categories: Elon Musk, transportation

Does that spell the end of the project?

It’s not looking good for Elon Musk’s hyperloop. The site of the futuristic train-like vehicle is now going to be turned into a parking lot, according to a report by Bloomberg published on Thursday.

Still, it’s not all doom and gloom.

Scientists electrically charge ‘constipated’ clouds to make them rain

Posted by in category: futurism

Electrical charge can change the size of water droplets and cause them to ‘explode.’

A new scientific experiment has proven that electrically charging clouds can change the size of the droplets in fog or, possibly, droplets in a cloud that is having trouble moving to fall as rain.

The new experiment assists a “constipated cloud” in becoming rainy, according to a report published by The Guardian on Thursday.

New materials could enable longer-lasting implantable batteries

Posted by in categories: biotech/medical, engineering

For the last few decades, battery research has largely focused on rechargeable lithium-ion batteries, which are used in everything from electric cars to portable electronics and have improved dramatically in terms of affordability and capacity. But nonrechargeable batteries have seen little improvement during that time, despite their crucial role in many important uses such as implantable medical devices like pacemakers.

Now, researchers at MIT have come up with a way to improve the energy density of these nonrechargeable, or “primary,” batteries. They say it could enable up to a 50% increase in useful lifetime, or a corresponding decrease in size and weight for a given amount of power or energy capacity, while also improving safety, with little or no increase in cost.

The new findings, which involve substituting the conventionally inactive battery electrolyte with a material that is active for energy delivery, are reported today in the journal Proceedings of the National Academy of Sciences, in a paper by MIT Kavanaugh Postdoctoral Fellow Haining Gao, graduate student Alejandro Sevilla, associate professor of mechanical engineering Betar Gallant, and four others at MIT and Caltech.

Aubrey de Grey on longevity at scale

Posted by in categories: biotech/medical, education, life extension

New foundation aims for scientific and rhetorical value – and to run the debug cycle for longevity research.

The Longevity Investors Conference is quickly turning into one of the highlights in the longevity calendar, and we were delighted to be able to interview some of the speakers in a few ‘backstage’ moments.
