New materials mimic mussel adhesive proteins to deliver self-setting antibacterial hydrogels, seal fetal membrane defects, and target cancer cells with precision. Researchers collaborate on in-vivo testing of these innovative biomedical applications.
Researchers face challenges in engaging the public in their work due to institutional barriers and limited training. Leah Gerber recommends developing new incentives, communications training, and boundaries for scientists to prioritize public engagement.
Researchers studying ice sheet movement in Greenland and Antarctica have found that warming temperatures cause sea levels to rise. The speed of ice shelf movement has nearly doubled in recent years, leading to increased sea level rises and uncertainty about future projections.
Researchers found that warmer ocean temperatures weaken mussels' fibrous threads, making them more prone to detachment. This can have cascading effects on the marine food web and commercial mussel farming.
The symposium explores the leading edge of interdisciplinary collaboration in microscopy, featuring experts who are developing new techniques to visualize life processes at unprecedented spatial and temporal resolution. The goal is to advance the visualization of life from the scale of a single molecule to the whole organism., Research...
Efforts to reduce lead pollution have been largely successful, but the problem persists due to new industrial inputs and consumer product contamination. Blood lead levels remain high, with no known threshold for toxicity, posing ongoing health risks to people and animals worldwide.
Mentoring models can significantly improve diversity in STEM, according to Arizona State University's executive director, who will share concrete strategies at the AAAS annual meeting. The institute has developed successful programs that have contributed to over 89 PhDs and 59 underrepresented minorities since 2005.
Researchers propose bioenergy with carbon capture and storage (BECCS) and biochar as solutions to achieve net-negative emissions. BECCS captures CO2 emissions from power plants, while biochar uses pyrolysis to produce a fertilizer that absorbs atmospheric CO2.
Climate change is projected to increase the risk of heat waves, heavy rains, and droughts. Preparing resilient communities with disaster preparations, early warning systems, and well-built infrastructure can help mitigate these impacts.
Early humans lost hair to efficiently sweat away heat, later using decorative methods like tattooing and makeup to increase attractiveness. Researchers found evidence of early skin decoration through fossil records and molecular genetics.
Researchers at Northwestern University have made significant breakthroughs in understanding the effects of brain damage on language processing and recovery. Studies have shown that with targeted training, patients can regain speech abilities years after a stroke.
Dr. Bruce J. Peterson has made seminal contributions in oceanography, limnology, biogeochemistry, ecology, and hydrology through his use of new methods and scientific publications. His research on the freshwater cycle of the Arctic has made fundamental advances in understanding land-ocean interactions.
A research project in Malawi has led to significant increases in crop yields, with corn production rising by 200% through crop rotation. Meanwhile, children's weight and height have improved, meeting international norms for healthy children. The program's success is attributed to the adoption of bushy legumes and diverse crop rotations.
Aerobic exercise increases critical brain structures and improves cognition in children and older adults. Physical activity also reduces susceptibility to diseases like hypertension, diabetes, and osteoporosis.
Aphasia affects 80,000 people annually in the US, causing difficulty speaking and understanding language. Researchers at Brown University have developed a therapy to strengthen speech networks using guided speech and repetition exercises. Early testing with four patients showed improved precision and reduced errors.
Researchers worldwide are embarking on DEMO projects to demonstrate fusion energy production, following the construction of ITER in France. The challenges ahead include finding solutions to well-known scientific and technical issues.
A study by Northwestern University's Noshir Contractor aims to enhance cross-cultural mentoring among women in sustainable development. The researcher has created a social media recommender system that connects mentors and mentees across different regions and cultures.
As people move more often and become more urbanized, their skin color may lose its evolutionary advantage. With limited exposure to sunlight in cities, many people are at risk of a vitamin D catastrophe. Using vitamin D supplements is the safest way to address this issue.
Nicole Calakos studies synaptic defects in the basal ganglia that underlie compulsive behavior, including Huntington's and Parkinson's diseases. Mice with overactive metabotropic glutamate receptors exhibit impaired synaptic plasticity, leading to obsessive-like behaviors.
A computational model developed by Northwestern University's Dirk Brockmann can pinpoint the source of an outbreak and predict disease spread using transportation data. The model generates accurate findings on origin and predicted arrival times, providing a lifesaving advantage in responding to diseases.
Researchers at Duke University have developed a brain prosthetic that allows rats to sense infrared light as a tactile sensation, enabling them to navigate virtual environments and recognize textures. This breakthrough could lead to the development of neural prosthetics for quadriplegics to regain sensory perception.
