Author: Claire Hendershot, Broad Institute of MIT and Harvard Developing a new drug can take years of research and cost millions of dollars. Still, more than 90% of drug candidates fail in clinical trials, with even more that never make it to the clinical stage. Many drugs fail because they simply aren’t safe. Researchers at […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. There is strong evidence that […]
Jupiter spot’s decline may be due to fewer small storms Decreasing numbers of smaller storms that feed Jupiter’s Great Red Spot, the solar system’s largest windstorm, may be causing the spot to shrink, according to 3D simulations. Numerical simulations feeding the Great Red Spot a diet of smaller storms, as has been known to occur […]
Adopting a more sustainable energy portfolio is imperative to address and alleviate the impacts of climate change. A key process is energy harvesting versus energy “production”. In this vein, a potentially viable approach involves the conversion of dissipated heat into electrical energy via the use of thermoelectricity. This method has the potential to contribute significantly […]
The evolution of the human being has a complex form in which some branches bifurcate and form two different species and some different branches come together again and form individuals with a certain degree of hybridization. The only hominin remaining today is Homo sapiens and the last to disappear was Homo neanderthalensis. Neanderthals, our closest […]
You can think of our atmosphere as a big chemistry set, a global churn of gaseous molecules and particles that constantly bounce off and change each other in complicated ways. While the particles are very small, often less than 1% of the thickness of human hair, they have outsized impacts. For example, particles are the […]
Analysis amends human-Neanderthal genetic exchange Human genes may have been replacing Neanderthal genes as long ago as 250,000 years, accounting for the disappearance of the Neanderthal Y chromosome, according to a paper in Science that closely analyzes the gene flow from humans to Neanderthals instead of the reverse, as past research has done. The study […]
The evolution of the cosmic star formation rate density paints a dynamic picture of galaxy evolution, with rapid stellar build-up at redshifts above 2, followed by a stark drop in SFRs of galaxies towards the present day. The origins of this down-turn are likely due to a mixture of feedback processes, broadly categorized as caused […]
Memory is so much more than a storage unit in our minds. The people involved in memories influence what we recall, and, as our study shows, the connections we make between memories. Our memory helps us learn from experiences and develop new knowledge by integrating and updating information. This process goes beyond recalling individual events […]
