A cutting-edge radar system could be a front-line tool to fight dangerous space junk

Posted by in categories: mapping, satellites

Plenty of potential solutions have been put forward to deal with the problem, but they all face a similar problem at the first step: how to track the debris they’re attempting to eliminate. Enter a new idea from researchers in Iran — using a novel type of radar to detect and track space debris before it becomes a danger.

The novel type of radar is called inverse synthetic aperture radar, or ISAR. As one might expect from the name, it’s the opposite of synthetic aperture radar (SAR). SAR has become much more prominent lately, especially by satellites attempting to collect data about the Earth, especially terrain data that might be useful for geospatial mapping.

Breakthrough study reveals that human and octopus brains have common features

Posted by in categories: evolution, neuroscience

The study’s findings could play a crucial role in developing a complex brain.

A common feature that connects humans and octopuses has only recently been revealed. It may sound a little bit quirky to you, but not to scientists.

Published very recently in Science Advances today, a team led by Nikolaus Rajewsky of the Max Delbrück Center has now shown that their evolution is linked to a dramatic expansion of their microRNA repertoire.

Banned: Huawei and ZTE telecommunications ‘threat’ to national security, says US

Posted by in category: security

Huawei, ZTE, Hytera Communications Corp., Hikvision, and Dahua have made it to the list.

United States has prohibited selling and importing new Huawei and ZTE telecommunications devices due to “national security concerns.”

The Federal Communications Commission (FCC) approved new regulations that forbade the sale and import of new Huawei and ZTE, according to the documents released by the agency on Friday.

Tesla phones an ‘alternative’ if Apple and Google ‘boot’ Twitter, Musk responds

Posted by in categories: business, Elon Musk, mobile phones, sustainability, transportation

The business mogul’s opening up to more ‘free speech’ on Twitter may have ruffled some feathers.

Elon Musk might have just hinted at making Tesla phones (Tesla Pi) a reality if Apple and Google were to “boot” Twitter from their app stores.

“If Apple & Google boot Twitter from their app stores, @elonmusk should produce his own smartphone,” Liz Wheeler, a video podcaster, said in a Twitter thread on Friday.

Black Friday 2022 e-commerce reaches record $9.12B, Thanksgiving $5.3B; BNPL and mobile are big hits

Posted by in categories: biotech/medical, economics

Analysts and e-commerce leaders have been predicting a muted online holiday shopping season this year, with sales in the first three weeks of November essentially flat over a year ago due to a weaker economy, inflation, and more people returning to shopping in stores again in the wake of the Covid-19 pandemic. But on the face of it, the Thanksgiving long weekend appears to be more buoyant than expected — albeit growth has definitely slowed down this year after the pandemic-period boom.

Black Friday broke $9 billion in sales for the first time yesterday, with online sales of $9.12 billion, according to figures from Adobe Analytics. This is a record figure for the day, and up 2.3% on sales figures a year ago, and slightly higher than Adobe had estimated leading up to the day. Adobe doesn’t break out volumes in its report, so it’s hard to know if those figures are due to items simply costing more this year because of inflation, or if the higher numbers are a result of more buying.

Black Friday is a key focus for those gauging how the e-commerce market, and consumer confidence, are both faring in what is the most important and biggest period for shopping in the year.

Amazon to shut down food delivery business in India

Posted by in categories: business, food

Amazon will shut down its food delivery business in India by the end of the year, the retailer said Friday, retreating from a $20 billion vertical it entered less than three years ago.

The retailer will shut down the food delivery business, called Amazon Food, on December 29 in India. It launched Food in India in May 2020 in parts of Bengaluru. The company later expanded the service across the city, tying up with additional restaurants, but it never heavily promoted or marketed the platform.

“Customers have been telling us for some time that they would like to order prepared meals on Amazon in addition to shopping for all other essentials. This is particularly relevant in present times as they stay home safe,” the company said at the time of Food launch.

History Of AI In 33 Breakthroughs: Digital Storage

Posted by in categories: business, robotics/AI

On September 14, 1956, IBM announced the 305 and 650 RAMAC (Random Access Memory Accounting) “data processing machines,” incorporating the first-ever disk storage product. The 305 came with fifty 24-inch disks for a total capacity of 5 megabytes, weighed 1 ton, and could be leased for $3,200 per month.

In 1953, Arthur J. Critchlow, a young member of IBM’s advanced technologies research lab in San Jose, California, was assigned the task of finding a better data storage medium than punch-cards.


The information explosion (a term first used in 1941, according to the Oxford English Dictionary) has turned into the big digital data explosion. And the data explosion enabled deep learning, an advanced data analysis method, to perform today’s AI breakthroughs in image identification and natural language processing.

Humans v nature: our long and destructive journey to the age of extinction

Posted by in category: sustainability

The story of the damage done to the world’s biodiversity is a tale of decline spanning thousands of years. Can the world seize its chance to change the narrative?

The story of the biodiversity crisis starts with a cold-case murder mystery that is tens of thousands of years old. When humans started spreading across the globe they discovered a world full of huge, mythical-sounding mammals called “megafauna”, but by the end of the Pleistocene, one by one, these large animals had disappeared. There is no smoking gun and evidence from ancient crime scenes is — unsurprisingly — patchy. But what investigators have learned suggests a prime suspect: humans.
