A trawl through a library of more than 50,000 small molecules has identified a potential candidate to inhibit the spread of cancer cells throughout the body. The molecule targets a mechanism of tumor development that had previously been considered “undruggable,” and could open the door to further promising new candidates.
The largest sunspot seen in 24 years is rotating back to face the Earth, and it looks to have grown even bigger. Last month, the solar active region known as AR12192 entertained the world with the sunspot clearly visible to the naked eye as it produced a series of large flares. But, after spending some time over on the far side of the sun, it hasn’t finished impressing us yet.
Salt- and acid-tolerant bacteria with the potential to be used in mining processing have been uncovered in Australia’s Wheatbelt. The bacteria were found during a "bio-prospecting" survey and are likely to become more important in coming decades as high-grade ore runs out.
Taking vitamin B12 and folic acid supplements may not reduce the risk of memory and thinking problems after all, according to research. The study is one of the largest to date to test long-term use of supplements and thinking and memory skills.
A new study suggests how scientists might deliberately engineer superconductors that work at higher temperatures. These findings open a new chapter in the 30-year quest to develop superconductors that operate at room temperature, which could revolutionize society by making virtually everything that runs on electricity much more efficient.
The normally bland face of Uranus has become increasingly stormy, with enormous cloud systems so bright that, for the first time ever, amateur astronomers are able to see details in the planet's hazy blue-green atmosphere.
Diego Garcia-Bellido and a team from the Univ. of Adelaide found fossils that were confirmed as distant cousins to humans.
The frequency of both serious and fatal lab accidents in academic chemistry labs in the past few years has become increasingly alarming. Two new sets of guidelines are taking lab safety to an elevated level, seeking to change an organization’s culture rather than rule set.
The National Medal of Science, created by Congress in 1959, is the country’s highest honor for achievement and leadership in advancing the fields of science and technology. A 12-member presidential committee, presented by the National Science Foundation, selects the award recipients. Recently announced by President Obama, the editors catch up with 2014 National Medal of Science winners to get their thoughts on the award.
The Univ. of Chicago recently opened the first Passive House-certified laboratory in North America. The 2,800-sq-ft Warren Woods Ecological Field Station is only the fifth Passive House-certified laboratory in the world and the first outside of Germany.
The American Association of Chemistry Teachers is the first organization of its kind in the U.S. dedicated to improving chemistry education and providing specialized resources to more than one million K-12 chemistry and physical science teachers nationwide.
The success of an experimental tobacco-based pharmaceutical in saving the lives of two people with Ebola may finally force big pharma to take plant-based drugs seriously.
Jocelyn Dunn, an industrial engineering doctoral student at Purdue Univ., is a part of a project to live on a landscape mimicking Mars for eight months. Along with five other researchers, she will be living in a domed habitat emulating what settlers might have on Mars. While exploring the environment, they will wear spacesuits and their communications will be delayed by 20 minutes to emulate the drag they would experience on the Red Planet.
A European spacecraft made history today by successfully landing on the icy, dusty surface of a speeding comet— an audacious cosmic first designed to answer big questions about the origin of the universe. However, two harpoons that were meant to anchor it to the comet appeared not to have fired.
Researchers have demonstrated a new process to convert all biomass into liquid fuel, and the method could make possible mobile processing plants. The new method, called fast-hydropyrolysis-hydrodeoxygenation, works by adding hydrogen into the biomass-processing reactor and is made possible by development of a new catalyst and innovative reactor design.
