Researchers discover Chimno, the gene responsible for the juvenile stage in insects. This gene is present in mammals and could play a key role in cancerous processes.

The study, which was published in the journal eLife and led by the Institute for Evolutionary Biology (IBE, CSIC-UPF) and the IRB Barcelona, has revealed that the Chinmo gene is responsible for establishing the juvenile stage in insects. It also confirms that the Br-C and E93 genes play a regulatory role in insect maturity. These genes, which are also present in humans, act as a promoter and as a suppressor, respectively, of cancerous processes.

The results of the research, which was carried out with the fruit fly Drosophila melanogaster and the cockroach Blatella germanica, reveal that these genes have been conserved throughout the evolution of insects. Therefore, it is believed that they could play a key role in the evolution of metamorphosis.

A long, long time ago, back in the early exciting days of raltegravir, the first HIV integrase inhibitor, we learned something important from a clinical trial with disappointing results. The trial bore the (barely) hidden name of the company that developed the drug — SWITCHMRK, get it? — and had a profound impact on how we managed virologically suppressed patients for years.

What did we learn? Namely, that it was risky to switch stable people from their “high resistance barrier” regimen of lopinavir/ritonavir plus NRTIs to raltegravir plus NRTIs if they harbored viruses with NRTI resistance. Some of the participants who had a history of treatment failure who switched ended up experiencing virologic rebound with integrase inhibitor resistance, which made the switch to raltegravir not noninferior (sorry for the double negative) to continuing lopinavir/ritonavir.

The interpretation was that despite the potency and excellent tolerability of raltegravir — massively better than lopinavir/ritonavir — it wasn’t enough to maintain viral suppression reliably unless the NRTIs were also fully active. Based on these results, for years we steered clear of use of this valuable drug class in any setting where we couldn’t use at least one other fully active drug.

Security researchers have detailed the inner workings of the commercial Android spyware called Predator, which is marketed by the Israeli company Intellexa (previously Cytrox).

Predator was first documented by Google’s Threat Analysis Group (TAG) in May 2022 as part of attacks leveraging five different zero-day flaws in the Chrome web browser and Android.

The spyware, which is delivered by means of another loader component known as Alien, is equipped to record audio from phone calls and VoIP-based apps as well as gather contacts and messages, including from Signal, WhatsApp, and Telegram.

But they’re not the only ones. Multiple companies are working on haptic devices, like gloves or vests, to add a sense of touch to virtual experiences. And now, researchers are aiming to integrate a fourth sense: smell.

How much more real might that peaceful meadow feel if you could smell the wildflowers and the damp Earth around you? How might the scent of an ocean breeze amplify a VR experience that takes place on a boat or a beach?

Scents have a powerful effect on the brain, eliciting emotions, memories, and sometimes even fight-or-flight responses. You may feel nostalgic with the cologne or perfume a favorite grandparent wore, comforted by a whiff of a favorite food, or extra-alert to your surroundings if it smells like something’s burning.
