AI Could Make Quantum Computing Obsolete, Nobel Prize Winner Says

Last week, DeepMind’s Demis Hassabis said that AI might be able to solve problems that quantum computers were supposedly necessary for. Indeed he said that classical systems – AI run on conventional computers – can model quantum systems. Sounds like an innocent claim but is certain to upset a lot of quantum computing researchers. Hassabis bases his argument on the surprising success of Alphafold.

CAR T-Cell Therapy Generates Long-Lasting Remission for Leukemia Patients

Posted by in category: biotech/medical

Immunotherapies have shaped the cancer research space over the past decade, proving effective for the treatment of some advanced cancers that previously had no therapeutic options. Chimeric antigen receptor T-cell (CAR T-cell) therapy is one immunotherapeutic approach that has recently garnered significant attention. In brief, CAR T-cell therapy involves removing a patient’s immune cells, altering them in a laboratory setting to make them better primed to detect and kill cancer cells, and delivering the modified cells back to the patient.

A recent study published in the New England Journal of Medicine shows exciting new evidence of the benefits of CAR T cell therapy. The study (NCT04404660) tested the treatment modality called obecabtagene autoleucel (obe-cel), a CAR T-cell therapy that recognizes CD19, a marker expressed on leukemia cells. Unlike other CAR T-cell modalities used to treat leukemia, obe-cel recognizes the CD19 marker with only “intermediate affinity” instead of the “high affinity” recognition of comparable therapies. Researchers suspected the lower affinity associated with obe-cel would correlate with reduced adverse effects experienced by patients receiving other CAR T-cell therapies.

The phase 1b-2 multicenter study, which included 153 adults with relapsed or refractory B-cell acute lymphoblastic leukemia (ALL), revealed promising results. Of the 127 patients who received at least one infusion of obe-cel, 77% experienced remission, with 55% achieving complete remission. The observed remission rates were significantly higher than expected, indicating notable efficacy of the treatment.

How Artificial Intelligence Could Automate Genomics Research

Posted by in category: robotics/AI

New research from UC San Diego suggests that large language models like GPT-4 could streamline the process of gene set enrichment, an approach what genes do and how they interact. Results bring science one step closer to automating one of the most widely used methods in genomics research.

‘Electronic’ scalp tattoos could be next big thing in brain monitoring

Posted by in category: neuroscience

During an EEG test, technicians normally use rulers and pencils to mark up a person’s head before gluing electrodes across the scalp. These electrodes are then connected via long wires to a machine that records brain activity. Alternatively, a cap with electrodes can be directly placed on the head.

However, this whole process is time-consuming and inconvenient, say the developers of the new technology. It generally takes around one to two hours to set up an EEG test, said co-developer Nanshu Lu, a professor of engineering at the University of Texas at Austin. The electrodes then need to be monitored about every two hours because the glue that attaches them to the scalp dries up, she told Live Science in an email.

Study reveals how stem cells respond to environmental signals, with implications for IBD and colorectal cancer

Posted by in categories: biotech/medical, chemistry, health

A new study from The Hospital for Sick Children (SickKids) and Institut Curie reveals how stem cells sense and respond to their environment, with implications for inflammatory bowel disease and colorectal cancer.

Stem cells constantly adapt to their environment to maintain organ and tissue health, informed by and physical forces. When they do not function as intended, stem cells can result in a number of health conditions including (IBD) and colorectal (bowel) cancer, where they continue to divide until a tumor forms.

Until now, how stem cells sense the physical forces around them has remained unclear, but novel findings published in Science led by Dr. Meryem Baghdadi, a former SickKids postdoctoral researcher, Dr. Tae-Hee Kim at SickKids and Dr. Danijela Vignjevic at Institut Curie, has revealed that stem cells depend on two , called PIEZO1 and PIEZO2, for their survival.

Newfound mechanism may explain why some cancer treatments boost risk of heart disease

Posted by in categories: biotech/medical, health, neuroscience

A cancer therapy that prompts the body’s immune defenses against viruses and bacteria to attack tumors can make patients more vulnerable to heart attack and stroke. A possible explanation for this side effect is that the treatment interferes with immune regulation in the heart’s largest blood vessels, a new study suggests.

Led by researchers at NYU Langone Health and its Perlmutter Cancer Center, the new work focused on a potent class of cancer-fighting drugs called . These medications work by blocking molecules embedded on the surface of cells—immune checkpoints—which normally serve as “brake pedals” that prevent excess immune activity, or inflammation. Some tumors are known to hijack these checkpoints to weaken the body’s defenses, so by blocking the checkpoints, the treatments enable the to kill .

However, this treatment type may also trigger damaging levels of inflammation in the heart, brain, stomach, and other organs, the researchers say. For example, past studies have shown that about 10% of those with atherosclerosis, the buildup of hardened fatty deposits (plaques) within artery walls, have a heart attack or stroke following . However, the specific mechanisms behind this issue had until now remained unclear.
