In vertebrate retinas, specialized photoreceptors responsible for color vision (cone cells) arrange themselves in patterns known as the “cone mosaic.” Researchers at the Okinawa Institute of Science and Technology (OIST) have discovered that a protein called Dscamb acts as a “self-avoidance enforcer” for color-detecting cells in the retinas of zebrafish, ensuring they maintain perfect spacing for optimal vision.
A groundbreaking study has revealed a significant link between the frequency of chest X-ray referrals from GPs and earlier diagnosis and improved survival rates for lung cancer patients.
A study in Alzheimer’s & Dementia has demonstrated the high accuracy of plasma p-tau217 as a blood-based biomarker for detecting abnormal brain beta-amyloid (Aβ) pathology, a hallmark of Alzheimer’s disease (AD).
Chewing gum releases hundreds of tiny plastic pieces straight into people’s mouths, researchers said on Tuesday, also warning of the pollution created by the rubber-based sweet.
A new open-source model of brain metabolism—the most complex ever generated—has shown how altering key chemicals could restore aged cells to their youthful activity and resilience.
Scientists at deCODE genetics/Amgen have identified associations between bipolar disorder and rare loss-of-function variants in two genes.
Depression is a mental health condition that affects 280 million people worldwide. It is twice as common in women than men and this pattern starts to develop during adolescence. Researchers have studied the biological processes that drive depression in adults and have shown a potential role for the kynurenine pathway, but this is the first time it has been investigated in adolescents in relation to biological sex.
Hepatitis B is a liver infection caused by the hepatitis B virus (HBV), and long-term hepatitis B infections that last longer than six months are considered “chronic.” Chronic hepatitis B (CHB) poses a huge health care burden as it is a common cause of chronic liver disease and is also associated with the development of liver cirrhosis and liver cancer.
Atherosclerosis (AS) is a chronic inflammatory disease characterized by the buildup of lipids and immune cells in arterial walls, increasing the risk of cardiovascular conditions. While multiple factors contribute to AS, recent research highlights the role of copper, an essential trace element, in disease progression.
Researchers from NYU Abu Dhabi’s Advanced Microfluidics and Microdevices Laboratory (AMMLab) have developed an innovative sensing system that restores the missing tactile feedback in minimally invasive surgery (MIS), enhancing precision, ease of use, and safety. The new “off-the-jaw” system integrates force and angle sensors into the handle of laparoscopic tools, providing surgeons with real-time measurements of grasping forces and insights into tissue stiffness and thickness.
