Elon Musk’s SpaceX: Now 1 million Starlink user terminals OKed for US internet service

April 3rd, 2020 at 11:52 am » Comments Off

The Federal Communications Commission has approved SpaceX’s application to roll out a million user terminals in the US to connect with its growing Starlink satellite broadband network. The approval gives SpaceX a 15-year “blanket license for the operation of up to 1,000,000 fixed earth stations that will communicate with its non-geostationary orbit satellite system”.

Crumpled graphene makes ultra-sensitive cancer DNA detector

April 3rd, 2020 at 11:22 am » Comments Off

Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient’s blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it more than ten thousand times more sensitive to DNA by creating electrical “hot spots,” researchers at the University […]

Old human cells rejuvenated with stem cell technology

April 2nd, 2020 at 11:20 am » Comments Off

Old human cells can become more youthful by coaxing them to briefly express proteins used to make induced pluripotent cells, Stanford researchers and their colleagues have found. The finding may have implications for aging research. Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of […]

YC startup Felix wants to replace antibiotics with programmable viruses

April 2nd, 2020 at 11:17 am » Comments Off

Right now the world is at war. But this is no ordinary war. It’s a fight with an organism so small we can only detect it through use of a microscope — and if we don’t stop it, it could kill millions of us in the next several decades. No, I’m not talking about COVID-19, […]

A neural network can help spot Covid-19 in chest x-rays

April 2nd, 2020 at 11:05 am » Comments Off

COVID-Net could help scientists develop an AI tool that can pick up telltale signs. The news: An open-access neural network called COVID-Net, released to the public this week, could help researchers around the world in a joint effort to develop an AI tool that can test people for Covid-19. What is it? COVID-Net is a […]

Smartphone data reveal which Americans are social distancing (and not)

D.C. gets an ‘A’ while Wyoming earns an ‘F’ for following coronavirus stay-at-home advice, based on the locations of tens of millions of phones  Location data firm Unacast identified places where residents are engaging in more social distancing in green — and less in orange. If you have a smartphone, you’re probably contributing to a […]

Stanford makes giant soft robot from inflatable tubes

April 1st, 2020 at 1:19 pm » Comments Off

As much as we love soft robots (and we really love soft robots), the vast majority of them operate pneumatically (or hydraulically) at larger scales, especially when they need to exert significant amounts of force. This causes complications, because pneumatics and hydraulics generally require a pump somewhere to move fluid around, so you often see […]

How to understand – and report – figures for ‘Covid deaths’

April 1st, 2020 at 1:15 pm » Comments Off

Every day, now, we are seeing figures for ‘Covid deaths’. These numbers are often expressed on graphs showing an exponential rise. But care must be taken when reading (and reporting) these figures. Given the extraordinary response to the emergence of this virus, it’s vital to have a clear-eyed view of its progress and what the […]

The coronavirus is showing us how clean the air can be if electric cars were the norm

March 31st, 2020 at 11:18 am » Comments Off

With all the loss of lives and financial destruction that the coronavirus has brought us, it’s hard to look at silver linings from this crisis, but there’s one that’s becoming obvious: cleaner air. It might not last for long, but it’s giving us a glimpse at what we could experience if the world was to […]

Coronavirus: Robots use light beams to zap hospital viruses

March 31st, 2020 at 11:13 am » Comments Off

The UVD robot takes about 20 minutes to treat a room “Please leave the room, close the door and start a disinfection,” says a voice from the robot. “It says it in Chinese as well now,” Simon Ellison, vice president of UVD Robots, tells me as he demonstrates the machine. Through a glass window we […]

Researchers create stretchable super capacitors for our next wearables

March 31st, 2020 at 11:09 am » Comments Off

Carbon nanotube forests improve the stretchable supercapacitor’s performanceDuke University The supercapacitors still functioned well when stretched to eight times their original size. Imagine a new type of supercapacitor that can be repeatedly stretched to eight times its original size, yet still retaining its full functionality. Only after 10,000 cycles of charging and recharging does it […]
