Breaking into the 31st week of 2023, from July 31 to Aug. 6, not much is held in store in terms of launches. Up first this week — following an aborted launch attempt last week — Rocket Lab will launch Capella Space’s Acadia satellite to a mid-inclination low-earth orbit. Later, a momentous flight will take place, when the last Antares 230+ will fly to low-Earth orbit (LEO) during the NG-19 resupply mission to the International Space Station (ISS).

Following slightly more than a day later, a Chang Zheng 4C carrying the Fengyun-3F meteorological satellite will take to the skies from Jiuquan, China. Shortly after that, it will be the turn of a Falcon 9 transporting Maxar-built Galaxy 37 inside its fairing. It will be deployed into a geostationary transfer orbit (GTO), with the satellite reaching a geostationary orbit (GEO) by itself.

While Artificial Intelligence has the ability to crunch huge amounts of data in a short span of time, it still falls behind when it comes to finding an energy-efficient way to make complex decisions. Researchers from John Hopkins University in the US are now proposing that 3D cell structures that mimic brain functions can be used to create biocomputers.

The gut microbiota is a key player in multiple facets of human health, influencing disease development and prevention. An interdisciplinary collaboration is needed to unravel its complexities and to finding potential avenues for therapeutic interventions.

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature’s smallest building blocks.

It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers at the University of Bonn and ETH Zurich have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics. The publication has now been released in the journal Nature Physics.

If you cool water below zero degrees Celsius, it solidifies into ice. In the process, it abruptly changes its properties. As ice, for example, it has a much lower density than in a liquid state—which is why icebergs float. In physics, this is referred to as a phase transition.

CAR T-cell (chimeric antigen receptor) therapy, a promising form of immunotherapy, involves reprogramming the patient’s T cells to enhance their ability to identify and combat antigens on the surface of cancer cells.

However, this therapy, which is currently approved for the treatment of leukemia and lymphoma, has a significant downside. During the process of destroying cancer cells, many of the engineered T cells get contaminated with residual cancer antigens, leading them to attack fellow T cells. This eventually results in a decrease in the body’s population of cancer-fighting cells, opening the door for a recurrence of cancer.

A new Yale study, however, has identified a way to tame the self-destructive tendencies of these killer T cells. Simply fusing a molecular tail onto the engineered T cells used in therapy, researchers say, can inhibit their proclivity to attack each other. The study was published July 27 in the journal Nature Immunology.

According to the team, the soft gripper can be put to use right after it comes off the 3D printer and is equipped with built-in gravity and touch sensors, which enable it to pick up, hold, and release objects. “It’s the first time such a gripper can both grip and release. All you have to do is turn the gripper horizontally. This triggers a change in the airflow in the valves, making the two fingers of the gripper release,” said a statement by the university.

Could this be the future of medicine?

In order for chatbots to be useful to doctors and other health professionals, they are going to need access to the latest research. But current models simply don’t have access to data beyond their latest update. Daniel Nadler has been working to resolve this issue with his new startup OpenEvidence.

He plans to achieve his lofty goal by “marrying these language models with a real-time firehose of clinical documents,” Nadler told Forbes on Thursday. He claims that his new model “can answer with an open book, as opposed to a closed book.”
