Elon Musk blames data scraping by AI startups for his new paywalls on reading tweets

Posted by in categories: Elon Musk, robotics/AI

Now unverified accounts will only be able to see 600 posts per day, and for “new” unverified accounts, just 300 in a day. The limits for verified accounts (presumably whether they’re bought as a part of the Twitter Blue subscription, granted through an organization, or verification Elon forced on people like Stephen King, LeBron James, and anyone else with more than a million followers) still allow reading only a maximum of 6,000 posts per day.

Shortly after that, Musk tweeted that the rate limits would “soon” increase to 8,000 tweets for verified users, 800 for unverified, and 400 for new unverified accounts.

Astronomers identify 19 new Wolf-Rayet stars in Andromeda Galaxy

Posted by in categories: cosmology, evolution

Wolf-Rayet (WR) stars are not only hot, bright, and massive. They are also in an advanced stage of evolution, losing mass at an incredible rate.

While surveying the neighboring Andromeda galaxy, astronomers discovered a new batch of Wolf-Rayet stars.

Some huge stars in galaxies may develop into Wolf-Rayet stars before going supernova. That’s why, Wolf-Rayet stars are intriguing candidates for studying the universe’s evolution.

Euclid successfully launched into space by Falcon 9 rocket

Posted by in categories: cosmology, space travel

In three months, the tool will begin a six year exploration of dark energy and dark matter.

Dark energy and dark matter discovery tool Euclid successfully launched on a SpaceX Falcon 9 rocket from Cape Canaveral in Florida, USA, at 11:11 local time / 16:11 BST / 17:11 CEST on Saturday 1 July 2023. The first stage proceeded to return to Earth to be recaptured and reused at later flights.

A Nikola Tesla Statue That Provides Free Wi-Fi

Posted by in category: internet

Statues of famous and noteworthy people are a usual sight in a city or town, but one particular statue of Nikola Tesla in Palo Alto, California, in the heart of Silicon Valley, doesn’t just stand there and do nothing. It emits free Wi-Fi.

This is what it’s like to control an autonomous car from miles away

Posted by in categories: robotics/AI, transportation

The exit ramp is a long, curving slope, and you have to make sure the 50-foot big rig you’re driving carefully navigates the bend and doesn’t fly out of control at a high speed.

But the thing is, you’re not actually there. You’re in a room in Silicon Valley, watching the ramp unfold in front of you on several screens. That heavy load you’re carrying is thousands of miles away in Florida.

Welcome to teleoperated driving, or remote-controlled driving with a human in front of a steering wheel, brake, and gas pedals, and a “windshield” plastered with monitors. It’s a method that allows autonomous vehicles to operate without anyone inside. Instead, there’s a watchful remote driver, or operator,… More.

The NK cell checkpoint NKG2A maintains expansion capacity of human NK cells

Posted by in category: biotech/medical

Human natural killer (NK) cells are cytotoxic effector cells that are increasingly harnessed in cancer immunotherapy. NKG2A/CD94 is an inhibitory receptor on NK cells that has established regulatory functions in the direct interaction with target cells when engaged with its ligand, the non-classical HLA class I molecule HLA-E. Here, we confirmed NKG2A as a checkpoint molecule in primary human NK cells and identified a novel role for NKG2A in maintaining NK cell expansion capacity by dampening both proliferative activity and excessive activation-induced cell death. Maintenance of NK cell expansion capacity might contribute to the preferential accumulation of human NKG2A+ NK cells after hematopoietic cell transplantation and enrichment of functionally impaired NK cells in human cancers. Functional silencing of NKG2A for cancer immunotherapy is highly attractive but will need to consider that this might also lead to a reduced survival by driving activation-induced cell death in targeted NK cells.
