Google DeepMind spinoff Isomorphic Labs expects research of drugs it designed using artificial intelligence will begin this year, according to its Nobel Prize-winning chief executive officer.

Cancer cases surge in young; simple lifestyle changes to lower your risk
The rising trend of early-onset cancers in adults under 50, particularly women, is alarming. Genetic, lifestyle, and environmental factors contribute to this increase. Maintaining a healthy weight, quitting tobacco, avoiding alcohol, consuming fiber-rich foods, using sunscreen, and regular physical activity are small lifestyle changes that can significantly reduce cancer risk.
Brain implant that could boost mood by using ultrasound to go under NHS trial
In future, doctors hope the technology could revolutionise the treatment of conditions such as depression, addiction, OCD and epilepsy by rebalancing disrupted patterns of brain activity.
Jacques Carolan, Aria’s programme director, said: “Neurotechnologies can help a much broader range of people than we thought. Helping with treatment resistant depression, epilepsy, addiction, eating disorders, that is the huge opportunity here. We are at a turning point in both the conditions we hope we can treat and the new types of technologies emerging to do that.”
The trial follows rapid advances in brain-computer-interface (BCI) technology, with Elon Musk’s company Neuralink launching a clinical trial in paralysis patients last year and another study restoring communication to stroke patients by translating their thoughts directly into speech.
Study gathers new insight into the neural underpinnings of human cooperation
Collaboration and cooperation are key elements of human social interactions, which can contribute to the efficient achievement of shared goals. While many psychology and neuroscience studies have investigated cooperative behaviors among humans, the complex interplay between these behaviors and their neural underpinnings remain poorly understood.
A research team at Beijing Normal University, supervised by Dr. Yina Ma set out to further explore the neural basis of human cooperation, using a combination of behavioral tasks and intracranial electroencephalography (iEEG). Their paper, published in Nature Neuroscience, delineates distinctive neurocognitive profiles for different states during cooperative tasks.
“Our lab has long been dedicated to understanding how human brains communicate and interact in social contexts, such as collective decision-making, intergroup conflict and social cooperation,” Jiaxin Wang, co-first author of the paper, told Medical Xpress.
New water purification technology helps turn seawater into drinking water without tons of chemicals
As humans age, their brain function can progressively decline and they become more vulnerable to developing neurodegenerative diseases, such as dementia. Dementia and other progressive neurological conditions can significantly impair their memory, thinking skills and daily functioning, significantly reducing their quality of life.
Many psychology and neurological studies have tried to identify biological markers and lifestyle factors that can contribute to the development of dementia. Yet the contribution of psychological characteristics (e.g., traits, emotional well-being and cognitive resilience) to a decline in mental functions remains poorly understood.
Researchers at University of Barcelona, University College London (UCL), Normandy University and other institutes across Europe recently set out to fill this gap in the literature, by trying to determine whether specific sets of psychological characteristics relate to brain health in middle and late adulthood. Their paper, published in Nature Mental Health, identified three key psychological profiles that were linked to different cognitive and mental health trajectories after middle-age.
Student project discovers superconductor with hallmark of unconventional superconductivity
Researchers from Tokyo Metropolitan University have discovered a new superconducting material. They combined iron, nickel, and zirconium, to create a new transition metal zirconide with different ratios of iron to nickel. The findings are published in the Journal of Alloys and Compounds.
While both iron zirconide and nickel zirconide are not superconducting, the newly prepared mixtures are exhibiting a “dome-shaped” phase diagram typical of so-called “unconventional superconductors,” a promising avenue for developing high temperature superconducting materials which can be more widely deployed in society.
Superconductors already play an active role in cutting-edge technologies, from superconducting magnets in medical devices and maglev systems to superconducting cables for power transmission. However, they generally rely on cooling to temperatures of around four Kelvin, a key roadblock in wider deployment of the technology.
Re-engineered, blue light-activated immune cells penetrate and kill solid tumors
HERSHEY, Pa. — Immunotherapies that mobilize a patient’s own immune system to fight cancer have become a treatment pillar. These therapies, including CAR T-cell therapy, have performed well in cancers like leukemias and lymphomas, but the results have been less promising in solid tumors.
A team led by researchers from the Penn State College of Medicine has re-engineered immune cells so that they can penetrate and kill solid tumors grown in the lab. They created a light-activated switch that controls protein function associated with cell structure and shape and incorporated it into natural killer cells, a type of immune cell that fights infections and tumors. When these cells are exposed to blue light, they morph and can then migrate into tumor spheroids — 3D tumors grown in the lab from either mouse or human cell lines — and kill tumor cells. This novel approach could improve cell-based immunotherapies, the researchers said.
The findings were published today (Oct 23) in the Proceedings of the National Academy of Sciences. The researchers also filed a provisional application to patent the technology described in the paper.
