A new method for controlling naturally magnetized bacteria has improved the prospects of applying them as vehicles for intratumoral delivery of cancer drugs and in hyperthermia therapy.

Modern molecular techniques have progressed to the point where sequencing can seem almost quaint. At the Basic Science Symposium of The Liver Meeting 2022, new techniques were on full display, with sessions devoted to epigenetics, microbiome analysis and spatial transcriptomics. But the first session was still on genetic variants in all their forms – rare variants, common variants and non-germline mutations.

By pairing the expression of an inhibitory ion channel with an activity-dependent promoter, researchers have developed the first on-demand gene therapy that specifically silenced hyperactive cells and prevented epileptic seizures.

Diwali, the Festival of Light, marks different events depending on where it is celebrated. In some areas of India, it marks the return of Lord Rama to his birthplace of Ayodhya after defeating the demon Ravana.

Diwali, the Festival of Light, marks different events depending on where it is celebrated. In some areas of India, it marks the return of Lord Rama to his birthplace of Ayodhya after defeating the demon Ravana. For Vivek Subbiah, associate professor at the Department of Investigational Cancer Therapeutics, Division of Cancer Medicine of the MD Anderson Cancer Center, the story of how Rama defeated Ravana has parallels in drug discovery. Ravana had 10 heads, and when one was cut off, it grew back. Rama defeated Ravana by means of a magic arrow that entered through the demon’s navel.

There is little doubt that progress in many brain diseases is being hampered because many, maybe most, diagnostic categories do not reflect underlying brain processes. In other disease areas, modern genetic and genomic methods have arrived in the form of approved drugs, from KRAS inhibitors in cancer to PCSK9 inhibitors to lower cholesterol. But brain diseases are different. Psychiatry is simultaneously the most personal area of medicine, and the least precise.

Peking University researchers in collaboration with the NIH have discovered a new biochemical pathway related to a bacterium that eliminates nicotine in the intestine. The findings could lead to new ways to improve nonalcoholic fatty liver disease in smokers.

“Epilepsy is really a classical neurological disorder,” Lars Pinborg told the audience at the European College of Neuropsychopharmacology (ECNP) annual conference on Sunday. “Or is it?” Pinborg, of Rigshospitalet's The Neuroscience Center in Denmark, was chairing a session dedicated to an alternative hypothesis, summed up in the session title: “Is epilepsy a psychiatric disorder?”
