How whale shark rhodopsin evolved to see, in the deep blue sea      (via sciencedaily.com) 

A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions -- one of which is counterintuitively associated with congenital stationary night blindness in humans -- aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.

Highly charged ions melt nano gold nuggets      (via sciencedaily.com)     Original source 

Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.

The powerhouse of the future: Artificial cells      (via sciencedaily.com) 

Researchers identify the most promising advancements and greatest challenges of artificial mitochondria and chloroplasts. The team describes the components required to construct synthetic mitochondria and chloroplasts and identifies proteins as the most important aspects for molecular rotary machinery, proton transport, and ATP production. The authors believe it is important to create artificial cells with biologically realistic energy-generation methods that mimic natural processes; replicating the entire cell could lead to future biomaterials.

First silicon integrated ECRAM for a practical AI accelerator      (via sciencedaily.com) 

The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.

HIV genomes that hide in white blood cells offer new target to eliminate infections      (via sciencedaily.com) 

To develop treatments that may one day entirely rid the body of HIV infection, scientists have long sought to identify all of the places that the virus can hide its genetic code. Now, in a study using blood samples from men and women with HIV on long-term suppressive therapy, a team of scientists reports new evidence that one such stable reservoir of HIV genomes can be found in circulating white blood cells called monocytes.

Human cells help researchers understand squid camouflage      (via sciencedaily.com) 

Squids and octopuses are masters of camouflage. But some aspects of how they become reversibly transparent are still 'unclear,' because researchers can't culture cephalopod skin cells in the lab. Now, researchers have replicated the tunable transparency of squid skin in mammalian cells, which are more easily cultured.

Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells      (via sciencedaily.com) 

Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
