Australian scientists have for the first time produced a new generation of experimental solar energy cells that pass strict International Electrotechnical Commission testing standards for heat and humidity.

The research findings, an important step towards commercial viability of perovskite solar , are published today in the journal Science.

Solar systems are now widespread in both industry and domestic housing. Most current systems rely on silicon to convert sunlight into useful energy.

A study published in Current Biology reports on one of the first comprehensive characterizations of poorly formed memories, and may offer a framework to explore different therapeutic approaches to fear, memory and anxiety disorders. It may also have implications for accuracy of some witness testimony.

Senior author Professor Bryce Vissel, from the UTS Centre for Neuroscience & Regenerative Medicine, said his team used novel behavioral, molecular and computational techniques to investigate memories that have not been well-formed, and how the deals with them. “For memories to be useful, they have to have been well-formed during an event—that is, they have to accurately reflect what actually happened.

”However, in the many memories are likely to be inaccurate—especially in situations where the experience was brief, sudden or highly emotional, as can often occur during trauma. Inaccurate memories can also occur when the is poorly encoded, potentially as a result of subtle differences in how each person processes memory or because of disease like Alzheimer’s or dementia.”

The feds have ordered 300 million doses of a potential coronavirus vaccine from British drugmaker AstraZeneca, officials said Thursday.

The company will get up to $1.2 billion from the US Department of Health and Human Services to speed the development and production of the vaccine with the goal of delivering the first doses as early as October, according to officials.

The deal between AstraZeneca and HHS’s Biomedical Advanced Research and Development Authority includes clinical studies that will start this summer with about 30,000 US volunteers, officials said.

A research study in mice by investigators at the University of Rochester Medical Center (URMC) suggests it would be possible to repair the brain cell damage caused by multiple sclerosis (MS). The research was published in the journal Cell Reports.

The research, led by Steve Goldman, professor of Neurology and Neuroscience at URMC and co-director of the Center for Translational Neuromedicine, manipulated embryonic and induced pluripotent stem cells to create glia, a type of brain cell. Glial progenitor cells, a subtype of these cells, eventually form the primary support cells of the brain, astrocytes and oligodendrocytes, which play essential roles in the health and signaling behavior of nerve cells.

MS is an autoimmune disorder where the body’s immune system attacks oligodendrocytes. Oligodendrocytes manufacture myelin, which makes the insulation that allows nerve cells to communicate with each other. As myelin decreases in MS, the signaling between nerve cells is interrupted, which causes the loss of function that leads to problems with sensation, motor function and cognitive problems.

But there’s just one problem, according to the magazine: Laser weapons basically don’t work underwater, where laser light scatters and gets absorbed almost immediately.

Top Secret

While public documents reveal certain details about the designs the Navy has been testing since at least 2011, the Navy has remained tight-lipped about the execution or purpose of such a system, PopMech reports. One theory, according to the magazine, is that the Navy plans to integrate the lasers into the submarines’ periscopes and use them as surface weapons.

Samsung has a hardened version of the Galaxy S20, but don’t reach for your credit card — it’s not what you were expecting, and you probably can’t get one. The company has introduced a Galaxy S20 Tactical Edition that, as the name suggests, is designed to meet the needs of the US military and federal government. It touts two layers of encryption strong enough to handle top secret data and connects to tactical radios and mission systems out of the box.

There are combat-related conveniences, too. One mode can turn the display on and off while you’re wearing night vision goggles, while a stealth mode turns off LTE and and mutes all RF broadcasts to eliminate even the slightest chance of eavesdropping. It’s also easy to unlock the phone in landscape mode so that you can quickly launch an app while the device is mounted to your chest.

This is otherwise a run-of-the-mill Galaxy S20 with a 6.2-inch, 1440p display, a Snapdragon 865 processor, 12GB of RAM, 128GB of expandable storage, a 4,000mAh battery and the usual arrays of front and rear cameras. Although Samsung shows the Tactical Edition in a rugged casing, there’s no mention of the phone itself being rugged.
