Scientists determine structure of a DNA damage ‘first responder’ — ScienceDaily

[ad_1] DNA is often likened to a blueprint. The particular sequence of As, Cs, Gs, and Ts in DNA provides information for building an organism. What’s not captured by this analogy is the fact that our DNA requires constant upkeep to maintain its integrity. Were it not for dedicated DNA repair machinery that routinely fixes…

New enzyme discovery is another leap towards beating plastic waste — ScienceDaily

[ad_1] Scientists who helped to pioneer the use of enzymes to eat plastic have taken an important next step in developing nature-based solutions to the global plastics crisis. They have characterised an enzyme that has the remarkable capacity to help break down terephthalate (TPA), one of the chemical building blocks of polyethylene terephthalate (PET) plastic,…

Genomic analysis supports ancient Muwekma Ohlone connection — ScienceDaily

[ad_1] A new genetic comparison study between ancient people buried east of San Francisco Bay and modern members of California’s Muwekma Ohlone people supports the tribe’s assertion — backed by family histories, government records and records from the Bay Area Spanish missions — that they and their ancestors have lived in this area longer than…

Finding ways to turn down the heat in cities — ScienceDaily

[ad_1] Rooftop gardens and greenery can help ease some of the severe heat in cities, according to research from climate scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. For several decades, researchers have promoted replacing black tar and other dark-colored roofing materials with bright, Sun-reflecting surfaces or “green roofs” full of…

Harnessing the power of AI to advance knowledge of Type 1 diabetes — ScienceDaily

[ad_1] An interdisciplinary team of researchers from the University of Missouri, Children’s Mercy Kansas City and Texas Children’s Hospital has used a new data-driven approach to learn more about persons with Type 1 diabetes, who account for about 5-10% of all diabetes diagnoses. The team gathered its information through health informatics and applied artificial intelligence…

With land grabs comes competition for water — and local farmers are likely to lose — ScienceDaily

[ad_1] Water from Ethiopia’s Omo River, which flows for 472 miles along the country’s southwest side, has helped sustain the livelihood of tribal populations for hundreds of years. Human rights organizations have estimated 200,000 people from various tribes in the region rely on the Omo’s water for cattle and to grow crops like sorghum and…

Researchers discover that anti-malaria drugs can fight pulmonary disease — ScienceDaily

[ad_1] A research team at Colorado State University has discovered that drugs used to treat malaria are also effective at treating a pulmonary disease similar to tuberculosis. Their findings were featured on the cover of the Feb. 23 issue of Science Translational Medicine. The study is a significant development in the fight against infections caused…

Engineers develop a ‘magnetic tentacle robot’ to pass into the narrow tubes of the lung — ScienceDaily

[ad_1] Engineers and scientists have developed proof of concept for a robot that can reach some of the smallest bronchial tubes in the lungs — to take tissue samples or deliver cancer therapy. Known as a magnetic tentacle robot, it measures just 2 millimetres in diameter, about twice the size of the tip of a…
