Mapping the biology of drug-resistant multiple sclerosis

Researchers from Duke University have identified two specific receptors, CXCR2 and LTBR, that play a key role in the development of drug-resistant multiple sclerosis. The study found that targeting these receptors may lead to successful treatment for patients who do not respond to interferon-beta treatment.

Food is hard to forget

A recent study published in Brain and Cognition found that lexical and semantic knowledge related to food is relatively well preserved even in diseases like Alzheimer's and Aphasia Primary Progressive. Food information was processed better than non-food, with caloric foods being more resiliently remembered.

Salty batteries

Sodium-oxygen batteries have shown improved cycle life and rechargeability thanks to a highly concentrated electrolyte solution. The new approach stabilizes DMSO in the presence of sodium, resulting in a passivating protective layer that enhances battery performance.

Blood vessels control brain growth

New UCL research reveals that blood vessels play a vital role in telling neural stem cells when and how to reproduce. The study found that preventing blood vessel growth interferes with normal neuron production, causing stem cells to disappear from the brainstem.

Scientists discover a cause of multiple resistance to cancer chemotherapy

Researchers at IDIBELL have found a common cause of multiple resistance in cancer chemotherapy, highlighting the loss of TP53TG1 molecule as a key driver. This discovery has significant implications for understanding treatment failure and may lead to new therapeutic strategies to overcome chemoresistance.

Tracing the ivory trail

A new study by the University of Utah uses radiocarbon dating and genetic analysis to track the origin of seized ivory, revealing that nearly all shipments come from elephants killed in the past three years. This intelligence can help combat illegal animal product trade and inform strategies for protecting elephant populations.

Common food additive promotes colon cancer in mice

A recent study published in Cancer Research found that emulsifiers in processed foods can alter the gut microbiota in mice, leading to increased tumor development and inflammation. The study suggests that dietary emulsifiers may be partially responsible for the increasing incidence of colorectal cancer worldwide.

New technique aids search for genetic roots of disease

A new technique allows researchers to quickly and cheaply generate DNA variants in a particular stretch of DNA, enabling the distinction between harmless and potentially hazardous genetic variations. This technique has the potential to speed up gene catalog creation and aid clinicians in interpreting genetic mutations.

Childhood cancer survivors living longer but do not report improvement in health status

A new study of over 14,000 childhood cancer survivors found that while treatments have extended their lifespan, patients do not report better health status. The study, which looked at three decades of therapy, highlights the need for interventions to improve quality of life and health outcomes for these survivors.
