The new zinc batteries are made up of electrodes that are screen-printed onto both sides of a sheet of hydrogel-reinforced cellulose paper. A layer of gold thin foil is coated on the electrodes to increase the conductivity of the battery. The battery is about 0.4mm thick, which is roughly the thickness of two strands of human hair.

Impressively, once the battery has reached the end of its lifespan, it can be buried in soil, where it will break down completely within a month.

The NTU researchers, who outlined their findings in the journal Advanced Science 0, demonstrated how a 1.5 in x 1.5 in (4 cm x 4 cm) square printed paper battery could power a small electric fan for up to 45 minutes. The researchers emphasized the fact that bending the battery did not interrupt the supply of power to the fan.

Having completed sea trials, it will now have its combat system activated.

Back in December of 2017, we brought you news of the U.S. Navy’s stealth destroyer the U.S.S. Monsoor breaking down during sea trails. At the time, we asked the question if this event would spell the end for Zumwalt-class destroyers?

It seems the Zumwalts are alive and well with the U.S. Navy’s third and final Zumwalt-class ship, the U.S.S. Lyndon B. Johnson, recently completing basic sea trials, according to 1945. This means that the massive ship will now have its combat system activated.

Zumwalt-class destroyers are top-of-the-range warships with advanced electrical generation systems. These systems power the ship’s engines, electronics, weapons, and propulsion systems.

Two different versions of the 35-meter-wide subsonic parachute flew perfectly.

The European Space Agency (ESA) completed the first successful high-altitude drop test of the ExoMars mission parachute, which will be the largest to ever fly on Mars, a press statement reveals.

The first and second stage parachutes have now both flown this year, meaning the ExoMars Rosalind Franklin rover mission is on course to launch for the Red Planet in Sept. 2022.

ExoMars mission is ‘on the road to launch’ The latest high-altitude drop tests took place in Oregon on Nov. 21 and Dec. 3 as part of a series of parachute tests aimed at ensuring the safe landing of the Exomars rover aboard the Kazachok lander, which is currently scheduled for some time in June 2023. The 35-meter-wide subsonic parachute will be the second parachute to deploy during the ExoMars descent modules final moments before touchdown. Two different versions of the 35-meter subsonic parachute were tested, with one developed by European firm Arescosmo, and the backup by U.S.-based Airborne Systems.

And it can allegedly survive a ‘once-in-10,000-years weather event’.

A safe reactor is a seaworthy reactor.

Or at least, it should be.

China claims its floating nuclear reactors, which will power off-shore oil rigs, can withstand “once-in-10,000-year” storms, according to an initial report from The South China Morning Post. That means hurricane-force winds, and more. To test its resilience, marine engineers subjected a model of the newly designed 60-megawatt reactors to strong winds and dangerously powerful undercurrents.

Referring to Tesla’s Autopilot and Full Self Driving features.

Elon Musk has claimed that no other CEO cares as much about safety as he does in an interview with Financial Times.

In the year that has seen his private wealth balloon like never before, Musk has also been showered with titles, beginning with the richest person in the world and more recently, the person of the year by Time Magazine. The Time accolade is probably one of the many titles Musk will receive as he embarks on his mission to send humanity to Moon with his space company, SpaceX.

Before we get there though, there are some issues with his other company Tesla that needs addressing. The company’s short history is peppered with incidents that have risked human lives as it pushes the boundaries of autonomous driving. The company offers features called Autopilot and Full Self-Driving (FSD) which are still in beta stages and have been involved in accidents. In August, this year, the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) launched an investigation into the Autopilot feature that involves 750,000 Tesla vehicles.

Speaking to FT, Musk said that he hasn’t misled Tesla buyers about Autopilot or FSD. “Read what it says when you order a Tesla. Read what it says when you turn it on. It’s very, very clear,” said Musk during the interview. He also cited the high ratings Tesla cars have achieved on safety and also used SpaceX’s association with NASA to send humans into space to highlight his focus on safety. He also went a step further to say that he doesn’t see any other CEO on the planet care as much about safety as he does.

Monash University, Australia scientists have discovered an enzyme that is key to why exercise improves our health. Importantly this discovery has opened up the possibility of drugs to promote this enzyme’s activity, protecting against the consequences of aging on metabolic health, including type 2 diabetes.

The proportion of people worldwide over 60 years old will double in the next three decades and by 2031, more than six million Australians will be over 65 years old. The incidence of type 2 diabetes increases with age so this aging population will also result in an increased incidence of the disease globally.

One of the main reasons for the increased prevalence of type 2 diabetes with age is the development of insulin resistance, or an inability for the body to respond to insulin, and this is often caused by reduced physical activity as we age.

Controversial facial recognition company, Clearview AI, which has amassed a database of some 10 billion images by scraping selfies off the Internet so it can sell an identity-matching service to law enforcement, has been hit with another order to delete people’s data.

France’s privacy watchdog said today that Clearview has breached Europe’s General Data Protection Regulation (GDPR).

In an announcement of the breach finding, the CNIL also gives Clearview formal notice to stop its “unlawful processing” and says it must delete user data within two months.

Wasn’t it science-fiction writer, futurist, inventor, undersea explorer, and television series host, Arthur C. Clarke, who said, “Any sufficiently advanced technology is indistinguishable from magic?” Yes, in fact, it was! And the same is true today! Technology is magic! And the great thing about living in the future is we get to reap the benefits of all this technological advancement. Who doesn’t want lazer-precise internet? Why not take a vacation in outer space? Where is the driverless car taking us? These are the questions we face when we take a look at the future — up close… 15 Emerging Technologies That Will Change Our World.

ROCHESTER, Minn. ― Adding messenger RNA, or mRNA therapy improves the response to cancer immunotherapy in patients who weren’t responding to the treatment, Mayo Clinic research shows. Immunotherapy uses the body’s immune system to prevent, control and eliminate cancer. The study is published in Cancer Immunology Research, a journal of the American Association for Cancer Research.

The phrase messenger RNA and its acronym, mRNA, have become familiar to the public during the COVID-19 pandemic. The mRNA vaccines for COVID-19 work by instructing cells in the body how to make a protein that triggers an immune response against the virus.

MRNA technology has also been of interest to cancer researchers and physicians. One of the major obstacles in cancer treatment is the low response rate in patients who receive immune checkpoint inhibitors to prevent an immune response from being so strong that it destroys healthy cells in the body.

In this video Dr. Lustgarten introduces his N of 1 experiment and gives an overview of the processes that he follows. He also discusses why he thinks it is important to track your own markers and not just rely on published trials.

Dr. Michael Lustgarten is a scientist at the Tufts University Human Nutrition Research Center on Aging in Boston, Massachusetts. His research currently focuses on the role of the gut microbiome and serum metabolome on muscle mass and function in older adults.
In this series of interviews Dr Lustgarten shares his experience with his rigorous n of 1 experiment over the last 7 years and shows how we or anyone can conduct a similar trial by tracking food, exercise and sleep, measure results and derive relationships between them, with a goal of extending our healthspan.
