Half a century after the last person walked on the moon, original footage has been digitally overhauled to show NASA’s lunar missions in a new light.
Several antiviral drugs kill viruses by inducing lots of mutations, but a computer model suggests this could have unpredictable consequences.
The almost unnoticed hack of MiMi points to a growing trend of software supply chain attacks, including by the Chinese government.
Iran’s recent seizure of unmanned US Navy boats shined a light on a pioneering Pentagon program to develop networks of air, surface and underwater drones for patrolling large regions, meshing their surveillance with artificial intelligence.
The year-old program operates numerous unmanned surface vessels, or USVs, in the waters around the Arabian peninsula, gathering data and images to be beamed back to collection centers in the Gulf.
The program operated without incident until Iranian forces tried to grab three seven-meter Saildrone Explorer USVs in two incidents, on August 29–30 and September 1.
What does GPT-3 “know” about me?

Large language models are trained on troves of personal data hoovered from the internet. So I wanted to know: What does it have on me?
Sure, asteroids did some of the work. But a few came from the fringes of our Solar System — and were kicked in by other stars.
A team of researchers at the University of Illinois Chicago has discovered a way to restore memory loss from Alzheimer’s disease in mice by boosting the production of neurons, the basic cells of the brain.
O.o!!!
According to recent research, the protein CHIP can control the insulin receptor more effectively while acting alone than when in a paired state. In cellular stress situations, CHIP often appears as a homodimer – an association of two identical proteins – and mainly functions to destroy misfolded and defective proteins. CHIP thus cleanses the cell. In order to do this, CHIP works with helper proteins to bind a chain of the small protein ubiquitin to misfolded proteins.
As a result, the cell detects and gets rid of defective proteins. Furthermore, CHIP controls insulin receptor signal transduction. CHIP binds to the receptor and degrades it, preventing the activation of life-extending gene products.
Researchers from the University of Cologne have now shown via tests using human cells and the nematode Caenorhabditis elegans that CHIP can also label itself with ubiquitin, preventing the formation of its dimer. The CHIP monomer regulates insulin signaling more effectively than the CHIP dimer. The research was conducted by the University of Cologne’s Cluster of Excellence for Cellular Stress Responses in Aging-Associated Diseases (CECAD) and was recently published in the journal Molecular Cell.
A set of six high-severity firmware vulnerabilities impacting a broad range of HP devices used in enterprise environments are still waiting to be patched, although some of them were publicly disclosed since July 2021.
Firmware flaws are particularly dangerous because they can lead to malware infections that persist even between OS re-installations or allow long-term compromises that would not trigger standard security tools.
As Binarly highlights in the report, even though it’s been a month since they made some of the flaws public at Black Hat 2022, the vendor hasn’t released security updates for all impacted models, leaving many customers exposed to attacks.
A growing number of ransomware groups are adopting a new tactic that helps them encrypt their victims’ systems faster while reducing the chances of being detected and stopped.
This tactic is called intermittent encryption, and it consists of encrypting only parts of the targeted files’ content, which would still render the data unrecoverable without using a valid decryptor+key.
For example, by skipping every other 16 bytes of a file, the encryption process takes almost half of the time required for full encryption but still locks the contents for good.
