Computer scientists from Rice University have displayed an artificial intelligence (AI) software that can run on commodity processors and train deep neural networks 15 times faster than platforms based on graphics processors.

According to Anshumali Shrivastava, an assistant professor of computer science at Rice’s Brown School of Engineering, the resources spent on training are the actual bottleneck in AI. Companies are spending millions of dollars a week to train and fine-tune their AI workloads.

Deep neural networks (DNN) are a very powerful type of artificial intelligence that can outperform humans at some tasks. DNN training is a series of matrix multiplication operations and an ideal workload for graphics processing units (GPUs), which costs nearly three times more than general-purpose central processing units (CPUs).

So far, it seems like it’s been the worst week of the year for social media platforms in terms of data leaks, with Clubhouse seemingly joining the fray.

Days after scraped data from more than a billion Facebook and LinkedIn profiles, collectively speaking, was put for sale online, it looks like now it’s Clubhouse’s turn. The upstart platform seems to have experienced the same fate, with an SQL database containing 1.3 million scraped Clubhouse user records leaked for free on a popular hacker forum.

We reached out to Clubhouse in order to confirm whether the leaked database was genuine and whether Clubhouse was aware of any breach to their systems. As of the time of writing this report, we did not receive a reply from the company.

Abstract

Metal and essential element concentrations during pregnancy and associations with autism spectrum disorder and attention-deficit/hyperactivity disorder in children

Prenatal exposure to toxic metals or variations in maternal levels of essential elements during pregnancy may be a risk factor for neurodevelopmental disorders such as attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in offspring.

Norway’s sovereign wealth fund has agreed to pay around 1.375 billion euros ($1.63 billion) for a 50% stake in one of the world’s biggest offshore wind farms, Orsted’s 752 megawatt (MW) Borssele 1 & 2 facility.

Managed by Norges Bank Investment Management, the fund — whose wealth stems from Norway’s vast North Sea oil and gas reserves — is the world’s largest and worth more than $1.3 trillion. In an announcement Wednesday, NBIM described the deal as its “first investment in renewable energy infrastructure.”

The transaction is set to complete in the second or third quarter of 2021. Under the terms of the deal, Orsted will retain its position as co-owner of the wind farm and handle operations and maintenance.

NASA has delayed the first flight of its Ingenuity Mars helicopter after a crucial test-spin of the drone’s rotor blades abruptly stopped.

This was the last major test to make sure the helicopter would be ready for its first flight, which was originally scheduled for early Monday. Now NASA has delayed the historic liftoff — which would mark the first powered, controlled flight on another planet — to Wednesday.

For the test on Friday, Ingenuity was supposed to spin its blades at full speed while on the ground. The two pairs of blades should have spun in opposite directions at more than 2500 rotations per minute — about eight times faster than an Earth helicopter. On flight day, they’ll need that speed to lift the 4-pound drone into the thin Martian atmosphere. That air has just 1% the density of Earth’s atmosphere, making Ingenuity’s task the equivalent of flying three times higher than the peak of Mount Everest.

Humanity’s first helicopter on Mars has been cleared for a historic takeoff.

Ingenuity will take to the skies above Jezero Crater Sunday (April 11) on a 40-second flight — roughly four times longer than the Wright brothers’ first flight on Earth over 117 years ago. The first data, successful or not, should flow back to Earth on Monday (April 12) around 3:30 a.m. EDT (0830 GMT).

As the first papers under these mandates are published, Plan S supporters say it’s the start of a journey towards open science. But most research funders haven’t signed up yet, and negotiations over the plan have produced a complex landscape of options to avoid paywalls. Here’s what the initiative means for scientists and journals — and some of the controversies that will play out in 2021 and beyond.

The push to remove journal paywalls officially started this year. Here’s how it works.

As they researched why the avalanche occurred with such force, researchers studying climate change pored over images taken in the days and weeks before and saw that ominous cracks had begun to form in the ice and snow. Then, scanning photos of a nearby glacier, they noticed similar crevasses forming, touching off a scramble to warn local authorities that it was also about to come crashing down.

The images of the glaciers came from a constellation of satellites no bigger than a shoebox, in orbit 280 miles up. Operated by San Francisco-based company Planet, the satellites, called Doves, weigh just over 10 pounds each and fly in “flocks” that today include 175 satellites. If one fails, the company replaces it, and as better batteries, solar arrays and cameras become available, the company updates its satellites the way Apple unveils a new iPhone.

The revolution in technology that transformed personal computing, put smart speakers in homes and gave rise to the age of artificial intelligence and machine learning is also transforming space. While rockets and human exploration get most of the attention, a quiet and often overlooked transformation has taken place in the way satellites are manufactured and operated. The result is an explosion of data and imagery from orbit.
