[ad_1] Kirsten Siebach has to persevere a little longer, waiting for her ship to arrive. That ship is in space and is carrying a rover called Perseverance to Mars. And Siebach, a Martian geologist at Rice University, is now one of 13 scientists recently selected by NASA to help run …

[ad_1] Hurricanes, pollution, disease, bleaching and the effects of an ever-warming planet all have a negative impact on the health of coral reefs around the world. However, those in the Caribbean are facing a new threat: an aggressive, golden-brown, crust-like algae that is rapidly invading shallow coral reefs. Algae, known …

[ad_1] The periodic table of the elements, created mainly by the Russian chemist Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance as an organizing principle in chemistry: all budding chemists know it from the earliest stages of their education. Given the …

[ad_1] The Borexino Experiment research team was able for the first time to detect neutrinos from the sun’s second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle). This means that now all theoretical predictions about how energy is generated inside the sun have also been experimentally verified. The findings …

[ad_1] Scientists from EPFL and the Friedrich Miescher Institute used cryo-electron microscopy to explain how a DNA-sensitive biomolecule that is key to our innate immune response is inactivated when it comes into contact with the cell’s DNA. One biomolecule that has garnered considerable attention in recent years is cGAS, a …

[ad_1] I. University chemistry professor Liviu Mirica and his colleagues found that diagnostic agents containing copper isotopes can detect amyloid deposits in the brain associated with Alzheimer’s disease. Photo by L. Brian Stauffer Researcher Hong-Jun Cho is the first author of the study. Photo courtesy of Hong-Jun Cho CHAMPAIGN, Ill. …

[ad_1] Two teams of scientists have resolved a longstanding controversy over the origins of complex life on Earth. The joint studies found that molecular fossils extracted from 635-million-year-old rocks are not the earliest evidence of animals, but instead common algae. Researchers from the Australian National University (ANU), Max Planck Institute …

[ad_1] If you’ve ever studied chemistry or biology, there’s a very good chance you’ve come across the common pictorial representation of what a chromosome should look like. As millions of high school and college students attest, it is a tall, narrow X shape, displaying the appearance of two chromatids joined …

[ad_1] Binary stars are systems containing two stars that orbit each other due to their mutual gravitational attraction. There is a range of different varieties of binary stars. A new study by researchers from Lund University, among others, studied binary stars made up partly of a normal star like our …

[ad_1] First introduced in wide use in the mid 1920sth century, nuclear magnetic resonance (NMR) has since become an indispensable technique for examining materials down to their atoms, revealing molecular structure and other details without interfering with the material itself. “It is a widely used technique in chemical analysis, material …
