Dana-Farber researchers identify interventions for breast and colorectal cancer that could redefine standard of care

Dana-Farber researchers have identified several promising interventions for breast and colorectal cancer, including a potential new treatment approach for stage III deficient DNA mismatch repair colon cancer and improved strategies for treating rare and aggressive forms of brain lymphoma. The findings will be presented at the 2025 Annu...

Megalodon: The broad diet of the megatooth shark

New research finds megalodon preyed upon a variety of species, including fish, sharks, and even crustaceans, contrary to the long-held belief that it targeted large marine mammals. The discovery was made by analyzing zinc isotopes in fossilized teeth, providing insights into the prehistoric shark's ecological versatility.

Unlocking T-cell plasticity in the tumor microenvironment: Insights into cancer immunotherapy and therapeutic innovations

The review highlights three key regulatory layers of T-cell plasticity: cellular signals, metabolic reprogramming, and physical and biological factors. Innovative therapeutic strategies, such as immune checkpoint therapy and adoptive cell therapy, aim to restore T-cell function and enhance antitumor immunity.

Physically decoupled, performance amplified: A new design for resonant sensors

Researchers introduce virtually coupled resonators (VCRs) that eliminate the need for mechanical links, unlocking higher amplitude ratio (AR) sensitivity and enabling dual-loop control systems. VCRs achieve a 2.7-fold increase in sensitivity and at least fourfold improvement in bandwidth over traditional weakly coupled resonators.

Integrating pharmacogenomic guided prescribing into routine clinical practice – promising results from the NHS PROGRESS study

The NHS PROGRESS study integrates pharmacogenomic guided prescribing into routine clinical practice, providing actionable guidance to clinicians. The study found that over 95% of patients received a pharmacogenomic result related to their medication, with nearly one in four prescriptions adjusted to safer or more effective treatments.

Researchers uncover neural circuit mechanism behind individual differences in innate fear

A study published in Neuron reveals the neural circuit underlying individual differences in visual escape habituation, a key component of emotional responses. The research identifies distinct brain pathways involved in two types of defensive behaviors, providing new insights into arousal modulation and stress adaptation.

HHS panel recommend statins for adults with HIV at risk for cardiovascular disease

The US Department of Health and Human Services Panel has recommended moderate-intensity statin therapy as the primary prevention among adults with HIV aged 40-75 years with low to intermediate 10-year atherosclerotic cardiovascular disease (ASCVD) risk. For those with a 10-year ASCVD risk score of 5% or higher, statin therapy is strong...

Research reveals missed opportunities to save George Floyd’s life

Researchers analyzed 12 videos of bystanders' attempts to intervene during the 2020 George Floyd killing. They found that bystanders made over 205 direct verbal interventions, with most focused on checking George Floyd's well-being. However, police mostly ignored or rejected these interventions, leading to his tragic death.
