LG is releasing a face-mounted, battery-powered air purifier
Korean electronics giant LG has adapted its home air purifying technology into a battery-powered, air purifying face mask with twin H13 HEPA filters, multi-speed fans and a UV-LED sterilizing case. But there’s still a lot we don’t know.
The PuriCare Wearable Air Purifier, as LG is calling it, appears quite a remarkable device. It straps to the face with straps behind the ears like a regular face mask, but carries an 820-mAh battery to run an active air filtration and purification system for up to eight hours on low mode and two hours on high.
Despite the limited supply of organs available for patients on waitlists for transplantation, organs from older, deceased donors are frequently discarded or not utilized.
Available older organs have the potential to close the gap between demand and supply that is responsible for the very long wait-times that lead to many patients not surviving the time it takes for an organ to become available.
Older organs can also often provoke a stronger immune response and may put patients at greater risk of adverse outcomes and transplant rejection. But, as the world population ages, organs from older, deceased donors represent an untapped and growing resource for patients in need. Investigators from Brigham and Women’s Hospital are leading efforts to breathe new life into older organs by leveraging a new class of drugs known as senolytics, which target and eliminate old cells.
Using clinical and experimental studies, the team presents evidence that senolytic drugs may help rejuvenate older organs, which could lead to better outcomes and a wider pool of organs eligible for donation. Results are published in Nature Communications.
“Older organs are available and have the potential to contribute to mitigating the current demand for organ transplantation,” said corresponding author Stefan G. Tullius, MD, Ph.D., chief of the Division of Transplant Surgery at the Brigham. “If we can utilize older organs in a safe way with outcomes that are comparable, we will take a substantial step forward for helping patients.”
A Ford Escape automatically stops as a pedestrian crosses in front during a self park demonstration, Tuesday, Aug. 25, 2020 in Detroit.
Ford, Bosch and real estate company Bedrock are teaming up to test technology that will let vehicles park by themselves in parking decks. The companies are testing the technology using floor-mounted sensors and computers that can control mainly existing features in the Ford Escape.
They say the technology is likely to arrive before widespread use of fully autonomous vehicles because sensors and computers inside parking decks can be used.

With the fall semester upon us, colleges and universities unveiled their plans for students—and many are just as quickly upending those plans. The University of North Carolina and Notre Dame recently announced they were changing their on campus plans as COVID-19 cases spiked. Many other universities are sure to follow. Already, universities ranging from Syracuse to Ohio State are suspending hundreds of students for violating social distancing rules, while COVID-19 outbreaks are on the rise on campuses such as the University of Alabama. While there is considerable variety in the actual plans, ranging from mostly in-person to all virtual, they all share one imperative: to maintain an economic model that is as imperiled by the pandemic as the hardest hit service industries.
Artist’s rendition of an array of microscopic robots
A troop of a million walking robots could enable scientific exploration at a microscopic level.
Researchers have developed microscopic robots before, but they weren’t able to move by themselves, says Marc Miskin at the University of Pennsylvania. That is partly because of a lack of micrometre-scale actuators – components required for movement, such as the bending of a robot’s legs.
Miskin and his colleagues overcame this by developing a new type of actuator made of an extremely thin layer of platinum. Each robot uses four of these tiny actuators as legs, connected to solar cells on its back that enable the legs to bend in response to laser light and propel their square metallic bodies forwards.
All types of business events are in danger of their revenue streams of tickets, sponsorships, memberships, and other types of fees being eroded. This is happening as the world gets used to digital formats and alternatives emerge to physical networking, matchmaking, and other tasks we get out of these events. The threat sounds familiar?
I won’t bury the headline: the vast, global events industry is going through its Napster moment through this pandemic, and is in denial on what this will do to it.
Everything about the underlying economics of this sprawling, diverse, chaotic and highly profitable sector is being undercut by the move to virtual, and 2019 may be the year where the industry’s revenues peaked. This year could be the event industry’s 2000 moment à la what happened to the music industry.
I was there during the music industry’s Napster moment in late ’90s, a cub reporter covering the vast promise of early internet, and wrote hundreds of stories about what happened to labels and the economic structure of music industry and music acts. I wrote about the atomization of the album into singles and the download boom with rise of Apple’s iTunes, and then the start of the streaming boom that led to Spotify and others since.
A 3D illustration of brown fat cells, which both burn and store energy
White fat cells can be turned into energy-burning brown fat using CRISPR gene-editing technology. These engineered cells have helped mice avoid weight gain and diabetes when on a high-fat diet, and could eventually be used to treat obesity-related disorders, say the researchers behind the work.
Human adults have plenty of white fat, the cells filled with lipid that make up fatty deposits. But we have much smaller reserves of brown fat cells, which burn energy as well as storing it. People typically lose brown fat as they age or put on weight. While brown fat seems to be stimulated when we are exposed to cold temperatures, there are no established methods of building up brown fat in the body.
Yu-Hua Tseng at Harvard University and her colleagues have developed a workaround. The researchers have used the CRISPR gene-editing tool to give human white fat cells the properties of brown fat.
Plexiglass, masks, warning signs: Is this the office of the future?
New York (CNN Business)Bustling skyscrapers and office parks packed with workers could be a relic of the pre-pandemic world.
The health crisis has forced millions of Americans to abandon their offices in favor of working from home, for better or worse. Now there are signs this may not be a short-term phenomenon, but more of a permanent shift in favor of remote work even after a Covid-19 vaccine is in place.
More than two-thirds (68%) of large company CEOs plan to downsize their office space, according to a survey released Tuesday by KPMG.
LONDON (Reuters) – It sounds like a surefire bet. You lend money to a borrower who puts up collateral that exceeds the size of the loan, and then you earn interest of about 20%.
What could possibly go wrong?
That’s the proposition presented by “DeFi”, or decentralised finance, peer-to-peer cryptocurrency platforms that allow lenders and borrowers to transact without the traditional gatekeepers of loans: banks.
And it has exploded during the COVID-19 crisis.
Loans on such platforms have risen more than seven-fold since March to $3.7 billion, according to industry site DeFi Pulse, as investors hunt returns at a time when central banks across the world have slashed interest rates to prop up economies battered by the pandemic.
Proponents say DeFi sites, which run on open-source code with algorithms that set rates in real-time based on supply and demand, represent the future of financial services, providing a cheaper, more efficient and accessible way for people and companies to access and offer credit.
But with the promise of high rewards comes high risk.
A new study detected over 33,000 unique virus populations that reside in human gut microbiomes
Researchers from Ohio State University have created the first catalog of viral populations known to inhabit the human gut. Called the Gut Virome Database, the study suggests each person’s gut viral population is as unique as their fingerprints.
Our gut microbiome has become a major focus of research over the past few years after the trillions of micro-organisms living in out digestive system were found to play a key role in maintaining human health. The vast majority of these organisms in our gut are bacteria, but the gut microbiome isn’t just a massive bacterial population – it also consists of parasites, fungi and viruses.
Cataloging these other microbiome inhabitants is not easy. Viruses, unlike bacteria, lack any universal genomic markers. In fact, anywhere from 40 to 90 percent of viral genomic sequences are known as “viral dark matter,” meaning they don’t align with any known reference virus sequences.
So the first step for the researchers was to compile data from dozens of prior studies looking at viruses in the human gut. The ultimate dataset compiled encompassed nearly 2,000 people spanning 16 countries.
China’s largest delivery company completed its first autonomous cargo drone flight
SF Holdings wants plane-size cargo drones to deliver goods to rural areas in China.
Companies around the world are building unmanned civilian aircraft for the freight business
Using small drones to deliver packages straight to your door isn’t a new idea: businesses from Amazon to UPS are already experimenting with the technology. But now the company that owns China’s largest express delivery service is taking the concept further.
SF Holdings said it successfully completed a trial of the country’s first unmanned cargo flight in northwest China last Friday. Unlike some companies that are testing small delivery drones to drop off a single package at nearby locations, SF’s aircraft is said to be capable of flying longer with a payload of up to 1.5 tonnes.
The giant drone is designed to reach a maximum flight distance of 1,200km at a speed of 180km per hour. On Friday, it flew nearly an hour from the mountainous region of Ningxia to Inner Mongolia.
This puts autonomous delivery into a different category from what many other companies have been working on. Amazon revealed last year that its Prime Air drone can fly up to 24km and deliver a package that weighs a little more than 2kg.
