Engineering Creates Molecules That Target Cancer-Causing Proteins
Researchers have developed a new drug that targets cancer-causing HER2 proteins while sparing healthy cells with normal HER2. Unlike current treatments, this engineered antibody recognizes a specific mutation on HER2 proteins that leads to uncontrolled cell growth. By converting the antibody into a bispecific T-cell engager, scientists ensured that one end binds to the mutant HER2 on cancer cells, while the other triggers immune cells to attack. Early tests in mice have shown promising results, as the treatment reduced tumor growth without significant side effects. This innovation may pave the way for precise cancer therapies targeting mutant proteins with fewer risks to healthy cells.

Could Poor Sleep in Middle Age Speed Up Brain Aging?
A recent study suggests a possible link between poor sleep quality in early middle age and signs of accelerated brain aging in later years. Published in Neurology, the research examined sleep patterns in 589 participants who were, on average, 40 years old at the study’s start. Brain scans, conducted 15 years later, revealed that individuals with multiple sleep issues—such as trouble falling asleep or staying asleep—showed signs of increased brain aging. Those with consistent poor sleep quality had brains appearing up to 2.6 years older than those with better sleep. While this research highlights an association rather than direct causation, the findings underscore the importance of managing sleep quality earlier in life to potentially slow brain aging.

DNA Stores Data in Bits After Epigenetic Upgrade
Scientists have developed a groundbreaking method for using DNA as a binary data storage system, allowing it to store information in strings of 0s and 1s, just like computers. This approach leverages DNA’s dense information capacity while adding methyl groups to represent bits. Unlike previous methods that embed data in the DNA sequence, this new method enables prefabricated DNA bricks to store data cheaply and quickly. The technique’s potential was demonstrated by encoding images, including a panda, in nearly 270,000 bits. While still costly, this development may one day offer a sustainable alternative to electronic storage, which struggles to meet rising data demands.
