New CRISPR tool enables more seamless gene editing — and improved disease modeling

Advances in the gene-editing technology known as CRISPR-Cas9 over the past 15 years have yielded important new insights into the roles that specific genes play in many diseases. But to date this technology — which allows scientists to use a ‘guide’ RNA to modify DNA sequences and evaluate the effects — is able to target, delete, replace, or modify only single gene sequences with a single guide RNA and has limited ability to assess multiple genetic changes simultaneously. Now, however, scientists have developed a series of sophisticated mouse models using CRISPR (‘clustered regularly interspaced short palindromic repeats’) technology that allows them to simultaneously assess genetic interactions on a host of immunological responses to multiple diseases, including cancer.

The hidden risk in SaaS: Why companies need a digital identity exit strategy

In the face of sudden trade restrictions, sanctions, or policy shifts, relying on SaaS providers outside your region for identity services is a gamble that companies can no longer afford to take. With trade disputes set to escalate, a sudden policy change could result in SaaS providers pulling out of regions or being forced to comply with new regulations that render identity services inaccessible. While software companies have yet to be put in the crosshairs, … More → The post The hidden risk in SaaS: Why companies need a digital identity exit strategy appeared first on Help Net Security.

AI will make ransomware even more dangerous

Ransomware is the top predicted threat for 2025, which is especially concerning given 38% of security professionals say ransomware will become even more dangerous when powered by AI, according to Ivanti. In comparison to the threat level, only 29% of security professionals say they are very prepared for ransomware attacks – leaving a significant gap in preparedness (29%), highlighting the need for more robust security measures. Strong understanding of exposure management among security leaders A … More → The post AI will make ransomware even more dangerous appeared first on Help Net Security.

Novel memristors to overcome AI’s ‘catastrophic forgetting’

Memristors consume extremely little power and behave similarly to brain cells. Researchers have now introduced novel memristive that offer significant advantages: they are more robust, function across a wider voltage range, and can operate in both analog and digital modes. Their unique properties could help address the problem of ‘catastrophic forgetting,’ where artificial neural networks abruptly forget previously learned information.

Producing nuclear fusion fuel is banned in the US for being too toxic, but these researchers found an alternative

Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method.
