Researchers develop electronic biosensing technology that can detect gene mutations indicative of cancer, potentially leading to faster and more accurate diagnoses. The new platform uses disposable arrays containing thousands of electronic sensors connected to powerful signal processing circuitry.
A consortium of cancer researchers has identified four chromosome locations with genetic changes that may alter a woman's risk of developing ovarian cancer. These findings are based on a large genome-wide association study and could lead to individualized risk assessments for ovarian cancer.
Researchers at the NHLBI found that adding tiotropium bromide to low-dose inhaled corticosteroids is more effective than doubling corticosteroids alone and as effective as adding a long-acting beta agonist. The treatment showed significant improvements in asthma control, including increased symptom-free days.
Researchers at Newcastle University create a wireless sensor that can withstand extreme temperatures to monitor volcanic activity and collect real-time data. The device uses Silicon Carbide electronics, which also offers radiation tolerance for potential use in the nuclear industry.
A new material can mark early-stage tumors using ultrasound imaging, potentially reducing the need for second surgeries and making operations more comfortable for patients. The durable material is made of porous glass spheres filled with a gas that helps it last longer.
Two studies found new genetic variants linked to ovarian cancer risk in the general population, particularly in women with serous ovarian cancer. The variants were more common in women with aggressive disease and may be used for closer surveillance and preventive approaches.
Researchers have discovered a new type of nanoparticle shaped like the Star of David, which may lead to new ways for sensing glucose in diagnosing diabetes. The nano-cages also showed promise as sensors for hydrogen peroxide detection, boosting electrical signals by 200 fold.
Researchers identified five genetic variants associated with increased breast cancer risk in BRCA1 carriers, including those related to estrogen-receptor-negative and triple-negative disease. These findings may help identify individuals at lower or higher risk of cancer, enabling tailored cancer prevention strategies.
HIV-1 virus uses ATP to remove AZT, a widely used AIDS treatment, allowing it to replicate itself. This discovery helps researchers understand why anti-AIDS treatments can fail, enabling the development of more effective treatments for HIV patients.
Scientists have found a key protein regulating biological clocks also regulates glucose production in the liver, improving diabetic mice health. Altering this protein can open new treatments for obesity and type 2 diabetes.
