This deep brain stimulator needs no batteries, only your breath

Posted by in categories: biotech/medical, neuroscience

“This is the first system that combines all the pieces; efficient energy harvesting, energy storage, and the controlled brain stimulator.”

Researchers have devised an ingenious way to power deep brain simulators — Using the person’s breathing movements.

About 150,000 deep brain stimulators are implanted every year. Normally placed under the skin in the chest area with electrodes implanted in the brain, these stimulators are known to help with neurological and psychiatric diseases when traditional treatments fail.

Solar cells one-thousandth the size of human hair can resist space radiation

Posted by in categories: physics, solar power, space, sustainability

Earth’s low orbit is filling up, meaning radiation-tolerant cell designs are required as satellites head to higher orbits. Will these new ones do?

Scientists have developed a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material. According to a new study published today (Nov .08) in the Journal of Applied Physics by AIP Publishing.

Significantly, the ultra-thin solar cells not only surpass earlier suggested thicker solar cells in resilience to irradiation; they also produce the same amount of power from converted sunlight after 20 years of use. Additionally, the novel photovoltaic cells could reduce load and considerably lower launch expenses. Barthel.

In a world first, astronomers observed a star with a solid outer surface

Posted by in category: space

“This was completely unexpected.”

Stars are essentially large fiery balls of plasma, which is often referred to as the “fourth state of matter” as it forms when gas is heated into a soup of positively charged ions and negatively charged electrons.

The star’s magnetic field is so strong it appears to have “frozen” its surface into a solid outer crust, a press statement reveals.

Meet the Large Hadron Collider, the world’s most powerful atom-smasher

Posted by in category: particle physics

The Large Hadron Collider is one of the most important scientific instruments in the world — and also one of the biggest humans have ever built.

The Large Hadron Collider is the world’s most powerful particle accelerator, situated along the border between Switzerland and France, just outside the Swiss city of Geneva. Still, that description doesn’t quite do it justice.

It is also one of the largest scientific instruments ever built; the result of a decade of collaboration between over 100 countries, hundreds of universities and scientific institutes, and more than 10,000 scientists and researchers.

A professor’s work on prime numbers could solve a 150-year-old puzzle in math

Posted by in category: mathematics

His work will be published soon.

Shanghai-born Zhang Yitang is a professor of mathematics at the University of California, Santa Barbara. If a 111-page manuscript allegedly written by him passes peer review, he might become the first person to solve the Riemann hypothesis, The South China Morning Post (SCMP)

The Riemann hypothesis is a 150-year-old puzzle that is considered by the community to be the holy grail of mathematics. Published in 1,859, it is a fascinating piece of mathematical conjecture around prime numbers and how they can be predicted.

This new VR headset will kill you if you die in an online game

Posted by in categories: entertainment, virtual reality

The designer has equipped the headset with explosive charges.

Palmer Luckey, the guy who co-founded the virtual reality (VR) headset-making company Oculus, has now made another VR headset that can kill you if you die in an online game. Luckey’s company was acquired by Facebook, now Meta, and his product is now a critical component of the metaverse that Mark Zuckerberg plans to build the company around.

At the outset, it might seem that Zuckerberg did the right thing by acquiring Oculus. Otherwise, we would not really know what sort of products they would bring to the market.

These engineered viruses are delivering DNA to E.coli instead of killing it- here’s why

Posted by in categories: bioengineering, biotech/medical

Turns out, altering bacteria from within could be the solution to antibiotic resistance.

In an ironic twist, researchers used viruses engineered with the CRISPR-Cas system to alter bacterial defense mechanisms and edit their genomes selectively in complex environments. Significantly, the novel approach may help address the pressing issue of antibiotic resistance.

Is the Higgs boson the first step to a ‘Star Trek’ transporter?

Posted by in categories: particle physics, satellites

A century after Albert Einstein came up with his theories of relativity, a constellation of Global Positioning System satellites is orbiting Earth, making practical use of his ground-breaking understanding of time.

If the discovery of the Higgs boson particle pans out, will even more mind-bending technologies result?

The future of manufacturing is iterative, collaborative and data-driven

Posted by in categories: biotech/medical, business, engineering

Digital transformation has been positioned as a cure-all to many of the challenges today’s enterprises face. But to fully reap the benefits of a digital transformation, businesses need to do more than just adopt the latest tools and apps. They also have to change their attitudes, practices and processes around data and technology, throughout their own organization and in their interactions with partners and customers.

“Digital transformation requires a jump on the technology side, but it requires a leap on the people side,” says Bill Gundrey, executive director for digital engineering and operations at Raytheon Missiles & Defense. “At Raytheon, digital transformation is a team sport. It impacts every function in our company, as well as customers and suppliers. We had to change the way people think about data and technology.”
