While many of us have a nebulous familiarity with the universe, a very clever animation by the Royal Observatory Greenwich explains the height and purposes of the different layers of the Earth’s atmosphere before it is officially considered to be “space”. These layers include the troposphere, stratosphere, mesosphere, and the Kármán Line. The thermosphere, which continues on and on eventually becomes the exosphere and then on to space as we know it.

Have you ever wondered how far away space is; how far are the different things you see above your head? Join the Royal Observatory Greenwich astronomers as they ascend up through the different layers of the Earth’s atmosphere to reveal what we would see at different heights.

The Royal Observatory also put together an equally clever animation that describes how the solar system was formed.

Wow!

USGS scientists and park staff stress that there’s nothing to worry about in terms of the supervolcano underlying Yellowstone.

“We have zero concerns that anything is happening volcanically,” Stovall said, adding that there hasn’t been a Yellowstone supervolcano eruption in more than 600,000 years. “There’s been geysers erupting through that whole time and that doesn’t mean that anything is happening with magma underground.”

Long regarded as a laggard in the fight against climate change, India is building massive solar stations at a furious clip, helping to drive a global revolution in renewable energy and reduce its dependence on coal and other carbon-spewing fossil fuels blamed for warming the planet.

G iving all men with suspected prostate cancer an immediate MRI scan would save thousands of lives a year, the results of a new study suggest.

A trial by British scientists found the comprehensive scan was 12 per cent more likely to detect dangerous tumours than the traditional biopsy, and that the number of men who undergo a biopsy needlessly could be reduced by 28 per cent.

Every year more than 120,000 men in the UK undergo a biopsy, which involves inserting an ultrasound probe into the affected area to take a sample of cells from the prostate that might contain cancer.

You may have heard of Numerai — the unorthodox hedge fund that crowdsources predictive stock market models from data scientists around the world. It is now seeking more brain power and announced today that it is giving away $1 million worth of cryptocurrency to Kaggle users who sign up. The San Francisco-based hedge fund incentivizes its community members by giving them digital tokens they can stake during tournaments to express confidence in their predictions. The best trading algorithms are then selected based on how they perform on the live market, and their creators are rewarded with more tokens.

Looking at most Wall Street hedge funds’ models, it’s fair to say open, collaborative efforts aren’t at their core. Movies like Wall Street, which portrays a greedy Gordon Gekko, and The Wolf of Wall Street, which highlights the derailing decadence of power and money, paint a rather unflattering picture of egocentric traders and financiers. Numerai founder and CEO Richard Craib is looking to change that.

The 30-year-old South African wants to create a more open and decentralized ecosystem for hedge funds. Rather than restricting access to trading data, Craib encrypts it before sharing it with his global network of data scientists, which effectively prevents them stealing and replicating the trades on their own. They can, however, use the shared information to build predictive models for the hedge fund.

Elon Musk has a reputation for pushing the envelop and making bold declarations. In 2002, he founded SpaceX with the intention of making spaceflight affordable through entirely reusable rockets. In April of 2014, his company achieved success with the first successful recovery of a Falcon 9 first stage. And in February of this year, his company successfully launched its Falcon Heavy and managed to recover two of the three boosters.

But above and beyond Musk’s commitment to reusability, there is also his longer-term plans to use his proposed Big Falcon Rocket (BFR) to explore and colonize Mars. The topic of when this rocket will be ready to conduct launches was the subject of a recent interview between Musk and famed director Jonathon Nolan, which took place at the 2018 South by Southwest Conference (SXSW) in Austin, Texas.

It seems Mastercard is gradually softening its stance on cryptocurrency, after CEO Ajay Banga downplayed non-government mandated digital currencies as “junk” back in October last year.

In a conversation with Financial Times, Ari Sarkar, Mastercard co-president for the Asia-Pacific region, said the company is open to explore cryptocurrencies created and backed by governments.

“If governments look to create national digital currency we’d be very happy to look at those in a more favourable way [compared with existing cryptocurrencies],” Sarkar told Financial Times.

Editor’s Note: The American Chemical Society is also issuing a press release today embargoed for 5am Eastern Time that can be requested at [email protected] or call 504−670−6721.

NEW ORLEANS, March 19, 2018 — Up until now, local inflammation and scar tissue from the so-called “foreign body response” has prevented the development of in-body sensors capable of continuous, long-term monitoring of body chemistry. But today scientists are presenting results showing tiny biosensors that become one with the body have overcome this barrier, and stream data to a mobile phone and to the cloud for personal and medical use.

“While fitness trackers and other wearables provide insights into our heart rate, respiration and other physical measures, they don’t provide information on the most important aspect of our health: our body’s chemistry,” explained Natalie Wisniewski, Ph.D. “Based on our ongoing studies, tissue-integrated sensor technology has the potential to enable wearables to live up to the promise of personalized medicine, revolutionizing the management of health in wellness and disease.” Dr. Wisniewski, who leads the team of biosensor developers, is the chief technology officer and co-founder of Profusa Inc., a San Francisco Bay Area-based life science company.
