What is the new LB.1 variant and is it causing a summer COVID-19 wave? Experts discuss symptoms, vaccines, isolation guidelines, and more.
A new antibiotic that works by disrupting two different cellular targets would make it 100 million times more difficult for bacteria to evolve resistance, according to new research from the University of Illinois Chicago.
In recent years, batteries have become ubiquitous in consumers’ daily lives. However, existing commercial battery technologies, which use liquid electrolytes and carbonaceous anodes, have certain drawbacks such as safety concerns, limited lifespan, and inadequate power density particularly at high temperatures.
Yet, there is an increasing need for batteries that can operate in extreme conditions, such as the high temperatures required in various industrial sectors, including medical device sterilization, subsurface exploration, and thermal reactors.
This has prompted researchers to search for solid electrolytes that are safe and compatible with lithium metal anodes, which are known for their high theoretical specific power capacity.
From 2018, Dr. Jon LaPook’s groundbreaking report following an Alzheimer’s patient and her caregiver husband for 10 years to document the struggles they face. From 2019, Bill Whitaker’s heartbreaking look at frontotemporal dementia. From July 2017, Lesley Stahl’s examination of efforts to prevent Alzheimer’s. And from this past January, Sharyn Alfonsi’s story on a new approach to brain surgery that could revolutionize the treatment of Alzheimer’s disease.

Researchers at the Technion – Israel Institute of technology in Haifa have shown that boosting a person’s mental state could help them recover from a heart attack.
The researchers focused on the reward system – a network in the brain that is activated when a person is motivated or in a positive emotional state – in order to ascertain its impact on recovery from a heart attack, formally known as an acute myocardial infarction (AMI).
They found that activating this system in mice led to better clinical outcomes and reduced scarring of the heart tissue. And while the science behind the link between the brain and the heart is still undefined, the Technion said the study raises hopes of improved treatment for heart disease.
A 13-year-old boy named Oran Knowlson has become the world’s first patient to test out a brain stimulation implant to treat severe epilepsy.
Knowlson was sometimes having hundreds of seizures per day before the device was fitted. His family has stated that he’s already seeing positive changes compared to his condition before implanting the device.
An exciting overview of progress made by the startup Tome Biosciences towards clinical application of the PASTE technology, a way of using CRISPR and integrases (or ligases) to programmably insert very long DNA sequences into the human genome.
Each year, Nature Biotechnology highlights companies that have received sizeable early-stage funding in the previous year. Tome Biosciences inserts large DNA sequences into precise genomic locations, overcoming limitations of base and prime editing.
Several studies have indicated that interrupted epigenetic reprogramming using Yamanaka transcription factors (OSKM) can rejuvenate cells from old laboratory animals and humans. However, the potential of OSKM-induced rejuvenation in brain tissue has been less explored. Here, we aimed to restore cognitive performance in 25.3-month-old female Sprague–Dawley rats using OSKM gene therapy for 39 days. Their progress was then compared with the cognitive performance of untreated 3.5-month-old rats as well as old control rats treated with a placebo adenovector. The Barnes maze test, used to assess cognitive performance, demonstrated enhanced cognitive abilities in old rats treated with OSKM compared to old control animals. In the treated old rats, there was a noticeable trend towards improved spatial memory relative to the old controls.
Trained on 1.5 million whole-slide images from 100,000 patients, a pathology foundation model is shown to improve performance of specialized models in detection of rare cancers.

Experts from the Universities of East Anglia, Sheffield, and Leeds have developed a new groundbreaking AI method that improves the accuracy and efficiency of analyzing MRI heart scans. This innovation could provide a way for faster, more accurate, and non-invasive diagnosis of heart failure and other cardiac conditions, thus saving valuable time and resources for the healthcare sector.
According to Innovation News Network, the research team used data from 814 patients at Sheffield and Leeds Teaching Hospitals to train an AI model, which was then tested using scans and data from 101 patients at Norfolk and Norwich University Hospitals to ensure accuracy.
