“When I first heard [of these startups], I thought this was going to be bad for the field,” Ramasamy tells Inverse. “This is going to be a disservice to our patients. And more importantly, I thought there was going to be some harm involved on the patient side.”

Direct-to-consumer telehealth companies aim to provide accessible, speedy, stigma-free care for everything from erectile dysfunction to herpes — without a physical exam. However, troubled by the risks of mistakes and misdiagnoses, as well as privacy breaches, some physicians and patients have been skeptical.

Then Covid-19 hit. In a pandemic that makes a visit to the doctor riskier than ever before, telehealth has seemingly come to the rescue, promising efficient care from the safety of home.

A widespread power outage left about 130,000 customers in darkness across a large area of Upper Manhattan early Friday, a Con Edison spokesman said.

Three networks in the utility’s transmission system in Manhattan lost their electricity supply at 5:13 a.m., Con Ed spokesman Philip O’Brien told The Post at 6:30 a.m., adding that the power has been restored.

“And we’re back! Here’s the moment electricity returned to upper Manhattan,” @kendisgibson said in a tweet.

In the first billion years, there was no oxygen on Earth. Life developed in an anoxic environment. Early bacteria probably obtained their energy by breaking down various substances by means of fermentation. However, there also seems to have been a kind of “oxygen-free respiration.” This was suggested by studies on primordial microbes that are still found in anoxic habitats today.

“We already saw ten years ago that there are genes in these microbes that perhaps encode for a primordial respiration . Since then, we—as well as other groups worldwide—have attempted to prove the existence of this respiratory enzyme and to isolate it. For a long time unsuccessfully because the complex was too fragile and fell apart at each attempt to isolate it from the membrane. We found the fragments, but were unable to piece them together again,” explains Professor Volker Müller from the Department of Molecular Microbiology and Bioenergetics at Goethe University.

Through hard work and perseverance, his doctoral researchers Martin Kuhns and Dragan Trifunovic then achieved a breakthrough in two successive doctoral theses. “In our desperation, we at some point took a heat-loving bacterium, Thermotoga maritima, which grows at temperatures between 60 and 90°C,” explains Trifunovic, who will shortly complete his doctorate. “Thermotoga also contains Rnf genes, and we hoped that the Rnf enzyme in this bacterium would be a bit more stable. Over the years, we then managed to develop a method for isolating the entire Rnf enzyme from the membrane of these bacteria.”

O,.o well then anything could be a computer even a mushroom or a rock :3.


A complex process can modify non-magnetic oxide materials in such a way to make them magnetic. The basis for this new phenomenon is controlled layer-by-layer growth of each material. An international research team with researchers from Martin Luther University Halle-Wittenberg (MLU) reported on their unexpected findings in the journal Nature Communications.

In solid-state physics, oxide layers only a few nanometres thick are known to form a so-called two-dimensional electron gas. These thin layers, separated from one another, are transparent and electrically insulating materials. However, when one grows on top of the other, a conductive area forms under certain conditions at the interface, which has a metallic shine. “Normally this system remains non-magnetic,” says Professor Ingrid Mertig from the Institute of Physics at MLU. The research team has succeeded in controlling conditions during growth so that vacancies are created in the atomic layers near the interface. These are later filled in by other atoms from adjoining atomic layers.

The and explanations for this newly discovered phenomenon were made by Ingrid Mertig’s team of physicists. The method was then experimentally tested by several research groups throughout Europe—including a group led by Professor Kathrin Dörr from MLU. They were able to prove the magnetism in the materials. “This combination of computer simulations and experiments enabled us to decipher the complex mechanism responsible for the development of magnetism,” explains Mertig.

The Army is developing a system to allow autonomous ground robots to communicate with soldiers through natural conversations — and, in time, learn to respond to soldier instructions no matter how informal or potentially crass they may be.

Researchers from the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory, working in collaboration with the University of Southern California’s Institute for Creative Technologies, have developed a new capability that allows conversational dialogue between soldiers and autonomous systems.

While new cases of the novel Coronavirus are still popping up in China, the country is facing yet another potentially contagious viral infection. This time, it’s jumping from ticks to people.

According to a report by Global Times, cases of the Severe Fever with Thrombocytopenia Syndrome (SFTS) virus first appeared in April and since then more than 37 people in East China’s Jiangsu Province have contracted with the virus and 23 people were found infected in East China’s Anhui Province. As of 6 August, around seven people have died from the infection.

Great interview with planetary scientist Isaac Smith, an expert on Mars polar science at York University in Toronto. Well worth a listen.


Three spacecraft are currently en route to Mars, but none will visit the poles. Yet Mars’ poles drive much of the Martian climate. And their understanding is key to deciphering what might have been happening on the Red planet some 3.5 billion years ago when it had lakes, deltas, rivers, and perhaps even transient oceans. I’m very pleased to welcome planetary scientist Isaac B. Smith of York University in Toronto — an expert on Mars polar science and exploration — to discuss the need for a Martian polar lander as well as a broader look at Mars science.
