Scientists at Lehigh University are developing a tiny generating plant, housed on a silicon chip, that they believe can produce enough hydrogen to run power-consuming portable devices.

The amount of hydrogen produced was small, but it was enough to demonstrate that the Lehigh project is feasible. Given time the Lehigh group believes they will develop a working generating plant, housed on a silicon chip that produces sufficient quantities of hydrogen to run different types of power consuming portable devices.

‘About 10 years ago people starting thinking: ‘can we take the same fabrication methods for silicon chips and instead of using them for electronics, use them for something else? said Mayuresh Kothare, assistant professor of chemical engineering.

I saw an ad for a tiny chip 1 that provides 5 volts 2 of isolated power: You feed 5 volts in one side, and get 5 volts out the other side. What makes this remarkable is that the two sides can have up to 5000 volts between them. This chip contains a DC-DC converter and a tiny isolation transformer so there’s no direct electrical connection from one side to the other. I was amazed that they could fit all this into a package smaller than your fingernail, so I decided to take a look inside.

I obtained a sample chip from Texas Instruments. Robert Baruch of project5474 decapped this chip for me by boiling it in sulfuric acid at 210 °C. This dissolved the epoxy package, leaving a pile of tiny components, shown below with a penny for scale. At the top are two tiny silicon dies, one for the primary circuitry and one for the secondary. Below the dies are two magnetized ferrite plates from the transformer. To the right is one of five pieces of woven glass fiber. At the bottom is a copper heat sink, partially dissolved by the decapping process. 3.

Doses of monoclonal antibodies—Covid-19 therapies authorized for emergency use last month—are sitting unused in hospital pharmacies, even as cases surge across the country.

Hospitals say the rollout of the therapies has been stunted by a lukewarm response from infectious-disease specialists, who say they want more clinical trial data before using them on a regular basis. Medical centers are also grappling with a lack of awareness and interest from both the primary-care doctors who would normally prescribe the drug and patients who are offered it. And some places are dealing with a shortage of space and staff to administer the therapies.

When monoclonal antibody therapies from Eli Lilly & Co. and Regeneron Pharmaceuticals Inc. were approved for emergency use in November, health agencies were worried there wouldn’t be enough supply to meet demand. Now, health-care providers are administering just 20% of the doses they receive each week, according to officials with Operation Warp Speed, the federal initiative to support development of new drugs, vaccines and diagnostics for Covid-19.

No escape.

Checking your notifications on a dive or live-streaming from the reef may not be such a far-off reality thanks to an underwater internet dubbed “Aqua-Fi.”

Developed by researchers at the King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia, Aqua-Fi uses a combination of lasers and existing computing technology to connect devices to the internet more than 30 feet underwater.

^The end of the year in cybersecurity mirrored the wider world by concluding in catastrophe: With more than 10000 people dying every day from Covid-19, a highly sophisticated electronic espionage campaign targeted U.S. government agencies and critical private industry, all customers of a single company: SolarWinds.

But there are some champions trying to make the online world a safer place. Our inaugural Forbes Cybersecurity Awards celebrate their achievements.

The constant pressure of gravity affects our thoughts and perception, but it’s so constant we haven’t noticed – until now.

Sometimes, looking at things we thought we knew with fresh eyes (and new tools) can lead to incredible discoveries.

That’s what happened when Jeff Weinell, a graduate research assistant at the University of Kansas’ Biodiversity Institute, found out that three specimens of snakes preserved in the institute’s biodiversity collection, found in field missions between 2006 and 2012 and overlooked up to this point, belonged in a category of their own.

The three snake specimens are the only known members of a new snake genus, called Levitonius, and a new snake species, called Levitonius mirus.

“FUJIFILM Corporation (President: Kenji Sukeno) is pleased to announce that it has achieved the world’s record 317 Gbpsi recording density with magnetic tapes using a new magnetic particle called Strontium Ferrite (SrFe)*4. The record was achieved in tape running test, conducted jointly with IBM Research. This represents the development of epoch-making technology that can produce data cartridges with the capacity of 580TB (terabytes), approximately 50 times greater than the capacity of current cartridges*5. The capacity of 580TB is enough to store data equivalent to 120000 DVDs.”

TOKYO, December 162020 — FUJIFILM Corporation (President: Kenji Sukeno) is pleased to announce that it has achieved the world’s record 317 Gbpsi recording density with magnetic tapes using a new magnetic particle called Strontium Ferrite (SrFe) *4. The record was achieved in tape running test, conducted jointly with IBM Research. This represents the development of epoch-making technology that can produce data cartridges with the capacity of 580TB (terabytes), approximately 50 times greater than the capacity of current cartridges *5. The capacity of 580TB is enough to store data equivalent to 120000 DVDs.

SrFe is a magnetic material that has very high magnetic properties and is stable to maintain high performance even when processed into fine particles. It is widely used as a raw material for producing magnets for motors. Fujifilm has applied its proprietary technology to successfully develop ultra-fine SrFe magnetic particles, which can be used as a magnetic material for producing particulate magnetic tape media for data storage. The company has been conducting R&D for commercial use of SrFe magnetic particles as potential replacement of Barium Ferrite (BaFe) magnetic particles, currently used in magnetic tape data storage media. Magnetic tapes used in this test have been produced at the company’s existing coating facility, confirming the ability to support mass production and commercialization.

COSPAR’s Planetary Protection Policy ensures scientific investigations related to the origin and distribution of life are not compromised.

Protecting the Earth from alien life sounds like the latest plot for a blockbuster thriller set in outer space. Whether it’s an invasion or a mysterious alien illness, the extraterrestrial threat to our planet has been well-explored in science fiction. But protecting the Earth from extraterrestrial contamination is not just a concept for our entertainment; as we explore further across our solar system and begin to land on our neighbouring planetary bodies, ensuring that we don’t bring potentially dangerous material home to Earth or indeed carry anything from Earth that may contaminate another planet is a responsibility we must take seriously.

So, who is responsible for ensuring that our space exploration is completed safely? Many nations around the world have their own space agencies, such as NASA and the European Space Agency, who run many different types of missions to explore space. States are responsible for their space activities under the Outer Space Treaty of 1967, including governmental and non-governmental actors. The Outer Space Treaty, among several provisions, regulates in its Article IX against harmful contamination. One of the core activities of the Committee on Space Research (COSPAR) is to develop, maintain, and promote a Policy on Planetary Protection, as the only international reference standard for spacefaring nations and in guiding compliance with Article IX of the Outer Space Treaty.
