A new gene panel may help personalize therapy for newly diagnosed glioblastoma patients by identifying those most likely to benefit from bevacizumab. Researchers observed a significant association between lower mesenchymal signatures and better survival in patients taking the drug.
A new drug called lambrolizumab has shown promising results in treating patients with advanced melanoma, with 77% of patients experiencing tumor response and minimal serious side effects. The treatment works by blocking a protein that allows cancer cells to hide from the immune system, reactivating an immune response to attack the cancer.
Oceanic oxygen levels decrease as ice sheets melt, leading to accelerated denitrification and a shift in the ocean's nitrogen cycle. Phytoplankton growth and productivity are affected, potentially altering atmospheric carbon dioxide concentrations.
A new therapy, magnetic resonance image-guided focused ultrasound (MRIgFU) ablation therapy, has significantly reduced pain in 67% of patients with bone cancer. The treatment uses heat to destroy tumors without invasive surgery.
A new method for manufacturing short, single-stranded DNA molecules has been developed by researchers at Karolinska Institutet and Harvard University. This technique can produce large amounts of DNA copies cheaply using bacteria, improving the quality and scalability of DNA fragment production.
Researchers developed a printing process called FLUENCE that produces semiconductors with strikingly higher quality than conventional methods. The technique enables thin films capable of conducting electricity 10 times more efficiently, paving the way for revolutionary advances in organic electronics.
A recent study found that night work can significantly impair glucose tolerance, increasing the risk of Type 2 diabetes among shift workers. The research showed peak glucose levels were 16% higher during night shifts compared to day shifts.
Researchers at MIT have identified 12 chemical compounds that help liver cells maintain their normal function while grown in a lab dish, and multiply to produce new tissue. The compounds can also mature induced pluripotent stem cells into fully functional hepatocytes.
Office workers with windows in their workplaces receive 173% more white light exposure during work hours and sleep an average of 46 minutes more per night. The research suggests that enhancing indoor lighting may improve office workers' physical well-being and sleep quality.
Researchers found that combining ipilimumab and nivolumab led to long-lasting tumor shrinkage in over half of patients with metastatic melanoma. The combination resulted in a 50% tumor size reduction in 40% of patients, with some experiencing shrinkages of over 80% within 12 weeks.
A Mayo Clinic-led study found that 45% of US oncologists experienced at least one symptom of burnout, despite 83% being satisfied with their careers. The study also revealed differences in practice characteristics between academic and private practices.
Researchers have identified a key growth factor, Fgf9, that promotes hair follicle regeneration after wounding. The study found that overexpressing Fgf9 in mouse models resulted in a two- to three-fold increase in new hair follicles produced.
A clinical trial found that adding bevacizumab to standard treatment for glioblastoma did not improve overall survival or progression-free survival. However, patients in the bevacizumab arm experienced a greater decline in cognitive function and symptom burden compared to those on placebo.
Experts urge for clear and unequivocal criteria to diagnose death, citing variability in brain death diagnosis and lack of global consensus. A proposed operational definition states death occurs when there is permanent loss of capacity for consciousness and loss of all brainstem functions.
A new study found that people with narcolepsy have a large increase in the number of neurons producing histamine, which may contribute to symptoms like preserved consciousness during cataplexy and fragmented nighttime sleep. This discovery suggests that drugs reducing histamine signaling at night may improve sleep in narcolepsy.
A subset of metastatic colorectal cancers responds to anti-EGFR drugs but develops resistance within months. The study found that MET gene amplification drives this resistance, and a blood test can detect its presence prior to relapse.
A Phase III study by MD Anderson Cancer Center found no overall survival (OS) or progression-free survival (PFS) benefits for bevacizumab in newly diagnosed glioblastoma patients. However, patients on bevacizumab experienced higher rates of toxicities and symptom burden compared to placebo.
Europe's national R&D budgets have stalled, leading to a brain drain and stunted scientific growth. Portugal's former science minister calls for sustained investment to strengthen universities and research facilities, promoting collaboration across borders.
A recent genome study identified genetic markers that can lead to higher yielding cocoa plants with better taste. Researchers sequenced the genome of the most commonly cultivated cacao plant and found a gene involved in pod color variation, which can help improve the quality of cocoa beans.
Researchers have discovered a new oncogene, RET rearrangement, which is present in 15.7% of lung adenocarcinoma patients and may be targeted with existing tyrosine-kinase inhibitors. This finding presents a promising treatment option for patients with this specific mutation.
A randomized phase III trial found sorafenib stops tumor growth and provides effective treatment for thyroid cancer patients who progress following standard therapies. The therapy also thwarts disease progression even among those whose tumors do not regress, with median progression-free survival of 10.8 months.
Researchers have discovered HER2 gene abnormalities in 14 different types of solid tumors, including breast, esophageal, and lung cancers. The study suggests that these irregularities may benefit from existing anti-HER2 therapies, providing new treatment options for patients with advanced cancer.
