SYDNEY, June 22 (Reuters) — Starlink, the satellite internet unit of Elon Musk’s SpaceX, expects to be able to provide continuous global coverage by around September but will then need to seek regulatory approvals, its president Gwynne Shotwel said on Tuesday.

“We’ve successfully deployed 1800 or so satellites and once all those satellites reach their operational orbit, we will have continuous global coverage, so that should be like September timeframe,” she told a Macquarie Group (MQG.AX) technology conference via webcast.

“But then we have regulatory work to go into every country and get approved to provide telecoms services.”

More than 90 years ago, astronomer Edwin Hubble observed the first hint of the rate at which the universe expands, called the Hubble constant.

Almost immediately, astronomers began arguing about the actual value of this constant, and over time, realized that there was a discrepancy in this number between early universe observations and late universe observations.

Early in the universe’s existence, light moved through plasma — there were no stars yet — and from oscillations similar to sound waves created by this, scientists deduced that the Hubble constant was about 67. This means the universe expands about 67 kilometers per second faster every 3.26 million light-years.

Clickbait headlines might not be as enticing to readers as once thought, according to a team of researchers. They added that artificial intelligence—AI—may also come up short when it comes to correctly determining whether a headline is clickbait.

In a series of studies, the researchers found that clickbait—headlines that often rely on linguistic gimmicks to tempt readers to read further—often did not perform any better and, in some cases, performed worse than traditional headlines.

Because fake news is a concern on social media, researchers have explored using AI to systematically identify and block clickbait. However, the studies also suggest that identifying fake news with artificial intelligence may be even more complicated than anticipated, said S. Shyam Sundar, James P. Jimirro Professor of Media Effects in the Donald P. Bellisario College of Communications and co-director of the Media Effects Research Laboratory.

The Export-Import Bank of the U.S. has arranged financing for the SpaceX launch of a Hispasat satellite, the first space deal it has done in six years.

WASHINGTON — The Export-Import Bank of the United States has arranged financing for the SpaceX launch of a Hispasat satellite, the first space deal the bank has done in six years.

Ex-Im announced June 21 that it approved $80.7 million in financing for a Falcon 9 launch of a Hispasat satellite, Amazonas Nexus, as well as launch and initial in-orbit insurance. The bank said the financing will be in the form of either a direct loan or a loan guarantee.

Biologists in the UK and Austria have discovered 71 new imprinted genes in the mouse genome.

Biologists at the Universities of Bath and Vienna have discovered 71 new ‘imprinted’ genes in the mouse genome, a finding that takes them a step closer to unraveling some of the mysteries of epigenetics – an area of science that describes how genes are switched on (and off) in different cells at different stages in development and adulthood.

To understand the importance of imprinted genes to inheritance, we need to step back and ask how inheritance works in general. Most of the thirty trillion cells in a person’s body contain genes that come from both their mother and father, with each parent contributing one version of each gene. The unique combination of genes goes part of the way to making an individual unique. Usually, each gene in a pair is equally active or inactive in a given cell. This is not the case for imprinted genes. These genes – which make up less than one percent of the total of 20000+ genes – tend to be more active (sometimes much more active) in one parental version than the other.

Chipmaker patches nine high-severity bugs in its Jetson SoC framework tied to the way it handles low-level cryptographic algorithms.

Flaws impacting millions of internet of things (IoT) devices running NVIDIA’s Jetson chips open the door for a variety of hacks, including denial-of-service (DoS) attacks or the siphoning of data.

NVIDIA released patches addressing nine high-severity vulnerabilities including eight additional bugs of less severity. The patches fix a wide swath of NVIDIA’s chipsets typically used for embedded computing systems, machine-learning applications and autonomous devices such as robots and drones.
Impacted products include Jetson chipset series; AGX Xavier, Xavier NX/TX1, Jetson TX2 (including Jetson TX2 NX), and Jetson Nano devices (including Jetson Nano 2GB) found in the NVIDIA JetPack software developers kit. The patches were delivered as part of NVIDIA’s June security bulletin, released Friday.

A global semiconductor shortage is causing havoc, delaying car production and affecting operations at large consumer electronics manufacturers.
