New deep reinforcement learning technique helps AI to evolve

Posted by in categories: robotics/AI, virtual reality

Hundreds of millions of years of evolution have produced a variety of life-forms, each intelligent in its own fashion. Each species has evolved to develop innate skills, learning capacities, and a physical form that ensures survival in its environment.

But despite being inspired by nature and evolution, the field of artificial intelligence has largely focused on creating the elements of intelligence separately and fusing them together after the development process. While this approach has yielded great results, it has also limited the flexibility of AI agents in some of the basic skills found in even the simplest life-forms.

Scientists pinpoint personality traits that increase risk of Alzheimer’s

Posted by in categories: biotech/medical, neuroscience

There is no cure for the disease, for which Alzheimer’s is the most common form (about 75% of dementia cases).

But finding out what raises the risk can help people try and prevent it.

A new study has offered more clues about the type of people who typically get Alzheimer’s.

UPDATED: Facebook changes parent company name to ‘Meta’

Posted by in categories: internet, virtual reality

Facebook chief Mark Zuckerberg on Thursday announced the parent company’s name is being changed to “Meta” to represent a future beyond just its troubled social network.

The new handle comes as the social media giant tries to fend off one its worst crises yet and pivot to its ambitions for the “metaverse” virtual reality version of the internet that the tech giant sees as the future.

Facebook, Instagram and WhatsApp will keep their names under the rebranding.

Can Blue Origin help replace the International Space Station?

Posted by in categories: business, life extension

So would the private station be a viable replacement for the ISS? The ageing station, which is a partnership between the US, Russia and other nations, is only funded until 2,024 with a 2028 extension looking probable, but it cannot last forever.

Blue Origin says its space station will be fully operational in the late 2020s, but deadline slippage is common when it comes to huge space-related projects like this one. “They can dream of being fully operational in the late 2020s, but in the space sector they often aim for aspirational targets and if they miss it by a year or two or three then they at least have something they’re aiming for until then,” says space analyst Laura Forczyk. “It’s almost inevitable that things take longer and are more expensive than planned.”

Hydrogen power generator for isolated areas, construction sites, events

Posted by in category: energy

Dubbed GEH2, the hydrogen system has a size of 1,150×2,200x3350mm and weighs in at 3.5 tons. It features IP43 ingress protection and is able to operate at temperatures between-5 and 45 degrees Celsius. Its output voltage is between 230 and 400 V.

The generator has a power of 110 kVA and its lifetime is guaranteed for two years or 15,000 hours. Its autonomy at 50% of prime running power is around eight hours. It can be started instantaneously and also features a double adduction system that allows continuous operation.

Sun fires off major solar flare from Earth-facing sunspot

Posted by in categories: particle physics, space

Solar particles blasted out in association with the flare could hit Earth tomorrow (Oct. 29).


A major solar flare erupted from the sun on Thursday (Oct. 28) in the strongest storm yet of our star’s current weather cycle.

The sun fired off an X1-class solar flare, its most powerful kind of flare, that peaked at 11:35 a.m. EDT (1535 GMT), according to an alert from the U.S. Space Weather Prediction Center (SWPC), which tracks space weather events.

The spike protein of SARS-CoV-2 variant A.30 is heavily mutated and evades vaccine-induced antibodies with high efficiency

Posted by in categories: biotech/medical, economics, health

The COVID-19 pandemic, caused by SARS-CoV-2, continues to rage in many countries, straining health systems and economies. Vaccines protect against severe disease and death and are considered central to ending the pandemic. COVID-19 vaccines (and SARS-CoV-2 infection) elicit antibodies that are directed against the viral spike (S) protein and neutralize the virus. However, the emergence of SARS-CoV-2 variants with S protein mutations that confer resistance to neutralization might compromise vaccine efficacy[1]. Furthermore, emerging viral variants with enhanced transmissibility, likely due to altered virus-host cell interactions, might rapidly spread globally. Therefore, it is important to investigate whether emerging SARS-CoV-2 variants exhibit altered host cell interactions and resistance against antibody-mediated neutralization.
