Scientists have discovered hundreds of unusually large, bacteria-killing viruses with capabilities normally associated with living organisms, blurring the line between living microbes and viral machines.

These phages — short for bacteriophages, so-called because they “eat” bacteria — are of a size and complexity considered typical of life, carry numerous genes normally found in bacteria and use these genes against their bacterial hosts.

I agree, Michael is 100 % spot-on-as usual. Dr Ian Hale.

Shana tells Inverse she’s been battling consistent fevers and muscle aches ever since the first, and most severe, symptoms subsided.

“I go through periods of hope mixed with periods of despair. I want to be able to run again and have the energy to do physical activity, but my body isn’t letting me,” she says. “I never expected this.”

Few recognize the vast implications of materials science.

To build today’s smartphone in the 1980s, it would cost about $110 million, require nearly 200 kilowatts of energy (compared to 2kW per year today), and the device would be 14 meters tall, according to Applied Materials CTO Omkaram Nalamasu.

That’s the power of materials advances. Materials science has democratized smartphones, bringing the technology to the pockets of over 3.5 billion people. But far beyond devices and circuitry, materials science stands at the center of innumerable breakthroughs across energy, future cities, transit, and medicine. And at the forefront of Covid-19, materials scientists are forging ahead with biomaterials, nanotechnology, and other materials research to accelerate a solution.

Memory is the natural extension of attention and learning. The act of memory facilitates the formation, activation, and retention of circuits that contribute to the brain’s optimal functioning. Dr. Restak explains how we are the sum total of the memory we retain. Without memory, we wouldn’t know who we are.

The hippocampus, a portion of the brain located in the temporal lobe of each cerebral cortex, is the entry portal for information to be remembered. If the hippocampus is damaged, we have difficulty forming new memories.

This was demonstrated by Patient H. M., whose real name was Henry Molaison. He started having seizures when he was 10 years old. By age 20, he was completely incapacitated.

An article about Jacob Gunn Glanville and team’s work.

As scientists race to create a vaccine, a parallel quest to engineer effective antibody treatments for the coronavirus is vital, too—and may provide relief sooner.

The MQ-25 could be more than just a tanker.

E-noses come in a variety of architectures, but most rely exclusively on chemical sensors, such as metal oxides or conducting polymers. The TruffleBot goes a step further: A 3.5-inch-by-2-inch circuit board that sits atop a Raspberry Pi contains eight pairs of sensors in four rows of two. Each sensor pair includes a chemical sensor to detect vapors and a mechanical sensor (a digital barometer) to measure air pressure and temperature.

Then comes the sniffing bit: Odor samples are pushed across these sensors by small air pumps that can be programmed to take up puffs of air in a pattern. “When animals want to smell something, they don’t just passively expose themselves to the chemical. They’re actively sniffing for it—sampling the air and moving around—so the signals that are being received are not static,” says Rosenstein.

A German startup has developed a modular marine platform able to simultaneously generate energy from three different renewable sources.

A new weapon in the arsenal against the coronavirus may be sitting in your home entertainment console. A team led by physicist Chris Barty of the University of California, Irvine is researching the use of diodes from Blu-ray digital video disc devices as deep-ultraviolet laser photon sources to rapidly disinfect surfaces and the indoor air that swirls around us.

Barty, UC Irvine distinguished professor of physics & astronomy, said that such UV light sterilizers would be cheap compared to current medical- and scientific-grade systems and that it’d be possible to deploy them almost anywhere.

“If these sources are successful, I think you could build them into a mask and clean the air that’s coming in and out of you,” he said. “Or you could set these things up in the air circulation ducts of major buildings, and the airflow that goes through could be sterilized.”
