SpinLaunch's rocket-free kinetic launch system conducts first test flight

SpinLaunch has been developing its alternative launch system since 2015, imagining a future where satellites and spacecraft can escape the Earth's atmosphere with zero emissions. It aims to achieve this with the help of a giant accelerator powered by an electric drive that it says could cut fuel use by four times and the costs by 10 times compared to traditional rocket launches, while also firing multiple payloads into orbit each day.
Initially, it is pursuing these ambitions through its Suborbital Accelerator. This consists of an upright disc-shaped, vacuum chamber that uses a carbon fiber tether to whip a projectile around to speeds of up to 8,047 km/h, before releasing it through a launch tube and upward through the atmosphere.

‘Dancing molecules’ successfully repair severe spinal cord injuries

Northwestern University researchers have developed a new injectable therapy that harnesses “dancing molecules” to reverse paralysis and repair tissue after severe spinal cord injuries.

In a new study, researchers administered a single injection to tissues surrounding the spinal cords of paralyzed mice. Just four weeks later, the animals regained the ability to walk.

The research will be published in the Nov. 12 issue of the journal Science. The study is now available online.

NVIDIA plans to build the world's most powerful Al supercomputer dedicated to predicting climate change, named Earth-2.

The earth is warming. The past seven years are on track to be the seven warmest on record. The emissions of greenhouse gases from human activities are responsible for approximately 1.1°C of average warming since the period 1850-1900.

What we’re experiencing is very different from the global average. We experience extreme weather — historic droughts, unprecedented heatwaves, intense hurricanes, violent storms and catastrophic floods. Climate disasters are the new norm.

We need to confront climate change now. Yet, we won’t feel the impact of our efforts for decades. It’s hard to mobilize action for something so far in the future. But we must know our future today — see it and feel it — so we can act with urgency.

To make our future a reality today, simulation is the answer.

#health India’s Covaxin COVID-19 vaccine 77.8% effective, Lancet study finds.

A new study in The Lancet is offering the first peer-reviewed and published data on the efficacy of Covaxin, a COVID-19 vaccine developed in India. The vaccine was found to be 77.8 percent effective at preventing symptomatic COVID-19 in a large Phase 3 clinical trial (more than 25,000 subjects, randomly allocated either two doses of the vaccine (administered four weeks apart) or two doses of placebo). No serious adverse events were detected in the trial.

Delivering chemotherapy drugs directly to cancers could help reduce side effects, and soon that job could be done by tiny 3D-printed robotic animals. These microrobots are steered by magnets, and only release their drug payload when they encounter the acidic environment around a tumor.

UBC researchers train computers to predict the next designer drugs

They have trained computers to predict the next designer drugs before they are even on the market, technology that could save lives.

Law enforcement agencies are in a race to identify and regulate new versions of dangerous psychoactive drugs such as bath salts and synthetic opioids, even as clandestine chemists work to synthesize and distribute new molecules with the same psychoactive effects as classical drugs of abuse. Identifying these so-called “legal highs” within seized pills or powders can take months, during which time thousands of people may have already used a new designer drug.

But new research is already helping law enforcement agencies around the world to cut identification time down from months to days, crucial in the race to identify and regulate new versions of dangerous psychoactive drugs.

New Lie Detector Can Read Facial Muscles You Don't Even Know You're Using

➖ @sciencetoall ➖

Just in time for METAverse launch researchers from MIT Media Lab presented their new invention. From a VR mask they made a sleep mask that records EEG, EOG, EMG, heart rate, head movement and skin temperature. While a person is sleeping, facial expressions and emotions are displayed in real time on their avatar in virtual reality.

Research has shown that facial muscle tension is consistent with the emotional content of the dream. Thus the dreamer is simultaneously in two quasi-realities: in his dream and in the metaverse, as an avatar.

Alphabet is putting its prototype robots to work cleaning up around Google’s offices

The company announced today that its Everyday Robots Project — a team within its experimental X labs dedicated to creating “a general-purpose learning robot” — has moved some of its prototype machines out of the lab and into Google’s Bay Area campuses to carry out some light custodial tasks.
“We are now operating a fleet of more than 100 robot prototypes that are autonomously performing a range of useful tasks around our offices,” said Everyday Robot’s chief robot officer Hans Peter Brøndmo

Meta AI + Google AI create a unified model for understanding all human languages.
In 2021, this is no longer a fantasy, but a purely engineering challenge.

XLS-R is a neural network for speech recognition, language detection and translation. It uses 2 billion parameters and nearly half a million hours of public available speech audio in 128 languages, nearly 10 times more than the previous Facebook system. The result is already impressive - a decrease in the error rate by an average of 14-34%.



The business goal of the planned breakthrough:
• The final solution for the simultaneous translation of human speech using mobile gadgets (the dream of science fiction writers of the 20th century)
• Voice communication of human-machine entities in the virtual environments (Metaverse, science fiction writers did not have enough imagination for that, but BigTech has)

Cancer: Key factor sustaining malignant tumor state identified

In a study published in Nature Cancer, researchers led by Prof. Cedric Blanpain, WELBIO investigator, Director of the Laboratory of Stem Cells and Cancer and Professor at the Université libre de Bruxelles (ULB), Belgium, demonstrated that NR2F2 is an essential regulator of malignant tumor state by controlling cancer stem cell and tumor maintenance in mouse and human cancers.

It seems that in the future people will be able to control their dreams. Researchers at the MIT conducted several studies on this topic. For example, they created a "smart" sleep glove. When you wear it while sleeping sensors record your muscle movements, heartbeat and electrical activity in your skin.

Then this device analyzes all the incoming data and accurately determines which sleeping phase you are in. At the right moment, the device emits a quiet sound signal - for example, the word "bunny"... And a bunny will suddenly appear in your dream. And it really works! The glove has been tested on 50 volunteers.

Is it good or not? Time will tell. Just imagine how they'll use that technology in an advertisement industry. The companies will get a chance to interfere your dream with «drive only BMW» - and you will.
