Intensity modulated radiotherapy (IMRT) enables physicians to deliver targeted radiation doses to tumors, improving treatment outcomes for various cancers. By using advanced imaging techniques and computer algorithms, IMRT minimizes damage to surrounding healthy tissues.
Researchers discovered a simple geometric explanation for protein spiral shapes, which could aid in understanding protein functions and structures. The finding uses mathematical ideas to optimize protein shape for maximum 'thickness,' leading to the natural occurrence of helical motifs in proteins.
Researchers at Ohio University are developing an algae-based system to remove carbon dioxide from smokestacks, reducing greenhouse gas emissions. The system uses photosynthesis and could process up to 20% of a plant's CO2 emissions, producing 200,000 tons of algae per year.
Experts examine parasitic and infectious diseases that can be spread by animals to people, highlighting the importance of integrated perspectives on human-animal interaction. The symposium aims to create a forum for discussing public health and food safety issues related to animal-human relationships.
Scientists at Northwestern University have identified the structure of the interaction complex between two molecules central to the allergic response in humans. The discovery could lead to a new class of drugs that target allergies at their source, preventing symptoms like itching and congestion.
A team of neuroscientists, led by University of Chicago neurologist John Milton, partnered with LPGA professionals to investigate how the brain manages complex physical tasks. They used functional MRI to study how professional golfers prepare to swing a club and how their brains acquire new skills.
Dr. Steven D. Douglas, a leading expert in immunology, has been recognized with the Erwin Neter Award for his groundbreaking research on innate immunity and disease. He has developed several major diagnostic tests used globally and is a leader in the Pediatric AIDS Clinical Trials Group.
Researchers at the University of Rochester have determined an improved pattern for artificial light-harvesting molecules, finding a point of diminishing returns for larger dendrimers. This breakthrough could lead to more efficient chemical reactions and applications in fields like medicine and renewable energy.
A study published by Emory University researchers found that a naturally occurring neurotransmitter called CART peptide produces behaviors associated with cocaine and methamphetamine. The finding suggests a role for the brain chemical in modulating or mediating the actions of drugs and potentially treating addiction.
Two studies found sigmoidoscopy detects few cancerous growths and none in asymptomatic patients with polyps, supporting the use of colonoscopy for regular screening. The research suggests that colonoscopy should be done every 5-10 years for people over 50 to save lives.
