Phase 2 CAR-T study reports significant remission rates at 15-month follow up

A Phase 2 study of axi-cel, a CD19-targeting CAR T cell therapy, reported remarkable improvement in outcomes for patients with relapsed or refractory large B-cell lymphoma. The study showed that 42% of patients remained in remission at 15 months, with complete responses in 54% and measurable responses in 82%.

A bird in the bush is worth $223,851 in the hand

A single Black-backed Oriole bird's arrival in rural Pennsylvania attracted over 1,800 birders from across the US and Canada, generating an estimated $223,851 for the local economy. The study reveals that ecotourism events can have a substantial impact on the economy through travel, food, and accommodation costs.

Sandy claws

Research by University of Delaware scientist Danielle Dixson and her team found that decorator crabs primarily decorate their arms and legs first, which helps them hide from predators. The study also showed that habitat presence affects decorating patterns, with crabs decorating faster in the absence of a shelter.

Transformation to wind and solar achievable with low indirect GHG emissions

A comprehensive study found that wind and solar energy have lower indirect greenhouse gas emissions compared to fossil-based technologies. The researchers' findings suggest that a full decarbonization of the global power sector is achievable with these clean energy sources, resulting in modest indirect greenhouse gas emissions.

Long-term prevention of organ rejection

Researchers at the University of Konstanz have successfully prevented chronic antibody-mediated organ rejection in a rat model using immunoproteasome inhibition with the selective inhibitor ONX 0914. This approach reduces activated plasma cells producing allo-antibodies and leads to improved renal function.

Extreme fieldwork, climate modeling yields new insight into predicting Greenland's melt

A UCLA-led team used extreme fieldwork and climate modeling to unravel a meltwater mystery on Greenland's ice sheet. They discovered that sunlight penetrating into the ice causes subsurface melting and storage of meltwater, leading to discrepancies between models' estimates and real-time data.

PARP inhibitor improves progression-free survival in patients with advanced breast cancers and BRCA

A Phase III trial led by MD Anderson Cancer Center found that talazoparib, a PARP inhibitor, extends progression-free survival and improves quality-of-life measures for patients with metastatic HER2-negative breast cancer and BRCA1/2 mutations. Talazoparib was associated with a 46% lower risk of progression compared to chemotherapy.

New study shows HIV-infected women not using statins as recommended

A new study published in AIDS Patient Care and STDs found that HIV-infected women do not use statins as recommended by guidelines, which control blood lipid levels to prevent heart disease. This underuse may accelerate cardiovascular disease in HIV-positive individuals, underscoring the need for improved cardiac health monitoring.

Boosting the antibiotic arsenal

MIT researchers discovered a way to make bacteria more vulnerable to quinolones, enabling existing drugs to kill bacteria that cause chronic infections. Delivering quinolones along with glucose and fumarate can eliminate several types of bacteria, including Pseudomonas aeruginosa and Staphylococcus aureus.

Controlled burns limited severity of Rim Fire

Researchers found that areas recently treated with controlled burns fared better in the 2013 Rim Fire. The best predictor of fire severity was how severe the area last burned, indicating that reducing initial burn severity can limit future fires.

Going undercover to fight tuberculosis

Researchers have developed a new antibiotic, EZ120, that targets the mycomembrane biosynthesis of tuberculosis pathogen Mycobacterium tuberculosis. By inhibiting key enzymes, EZ120 significantly increases the effectiveness of conventional antibiotics, offering a novel approach for tuberculosis treatment.
