A new study reveals that most massive stars in the early universe were born as binary systems, similar to those in our own galaxy. This finding provides the first strong evidence for the common existence of massive binary stars in the early universe, shaping black holes and supernovae.
UCLA investigators unveil decade-long survival data for immunotherapy in advanced lung cancer and promising results for novel therapies targeting PSMA, DKK1, and FGFR3 in various aggressive cancers. These breakthroughs hold promise for improved treatment outcomes and quality of life for patients with difficult-to-treat diseases.
Researchers have unveiled the molecular mechanisms underlying L1's retrotransposition and integration into genomic DNA. The study reveals that ORF2p interacts primarily with the DNA backbone through electrostatic forces, enabling site-specific cleavage during retrotransposition.
The Japan Science and Technology Agency hosts an international symposium on weather controllability technologies as part of Moonshot Goal 8. The goal aims to mitigate the effects of extreme weather disasters by 2050 through innovative research and development of weather-control technologies.
Researchers propose a novel analytical model that considers multiple nonlinear factors in motor performance calculation, reducing errors caused by magnetic saturation. The new method significantly improves design efficiency and prediction accuracy, cutting development time and cost.
A research team at DGIST developed a new alloy structure that enhances oxygen reduction reaction efficiency in hydrogen fuel cells. The catalyst, which combines platinum and transition metals with magnetic properties, exceeded durability targets set by the US Department of Energy.
Researchers proposed a four-level modulation strategy for dual three-phase open-winding PMSM drives, achieving higher efficiency and lower current harmonics. The proposed strategy reduces average current THD by more than 29% and switching frequencies by up to 90%.
Researchers at NIT Puducherry unveiled an energy-efficient model predictive current control (MPCC) method that enhances induction motor drive performance in electric vehicles. The CSVVV-based MPCC introduces a novel way to synthesize voltage vectors, reducing switching losses and current ripple.
A team of researchers identified a unique protein signature that can predict which patients are likely to resist standard therapies, paving the way for personalized treatments. By blocking a specific transporter system, they made tumors more sensitive to treatment, suggesting a promising new avenue for treating colorectal cancer.
A team of scientists has created a detailed model of how cells regulate traffic through the nuclear pore complex, revealing that flexible protein chains create an entropic barrier that admits only properly escorted cargo. This breakthrough sheds light on diseases like cancer, Alzheimer's, and ALS, where this transport system fails.
A new control strategy for hybrid magnetic bearing systems is proposed, employing an improved cascaded reduced-order linear active disturbance rejection controller. The strategy significantly enhances rotor suspension stability by employing feedforward compensation, reducing displacement fluctuations and improving system robustness. Ex...

Research reveals that even native ecosystems can't adapt to extreme drought conditions, leading to significant impacts on plant growth and productivity. Productivity declines by up to 77% in four years under consecutive extreme droughts.
A sub-study of KEYMAKER-U03 found pembrolizumab-based triplet combinations to be effective in treating advanced renal cell carcinoma, with an objective response rate of 78% and a median progression-free survival of 31.8 months. The most promising combination included pembrolizumab, belzutifan, and lenvatinib.
Patients receiving mRNA-based COVID vaccines showed improved survival rates and responses to immunotherapy, especially in 'cold' tumors with low PD-L1 expression. The study suggests that these vaccines can reprogram immune responses against cancer, potentially improving outcomes for patients with treatment-resistant disease.
A recent study found that patients with advanced lung and skin cancer who received a COVID-19 mRNA vaccine within 100 days of starting immunotherapy drugs lived significantly longer than those who did not get the vaccine. The observation marks a significant step toward a long-awaited universal cancer vaccine to boost tumor-fighting eff...
The VT3989 trial demonstrated a disease control rate of 86% in refractory mesothelioma patients, with notable partial responses and stable disease. The YAP-TEAD inhibitor also showed an encouraging safety profile, supporting continued clinical development in this unmet clinical need.
A clinical trial showed a new drug combination reduced deaths in patients with recurrent prostate cancer after surgery or radiation therapy. The combination of hormone therapy and enzalutamide cut the risk of death by 40%, offering a meaningful treatment option for high-risk patients.
A new antibody drug conjugate (ADC) sacituzumab govitecan has been shown to improve progression-free survival in patients with advanced triple-negative breast cancer who are ineligible for immune checkpoint inhibitors. The ADC targets the protein Trop2 on TNBC cells and delivers a potent chemotherapy drug directly to tumor sites.
