Research at the Queen’s University Belfast has produced a major (and mind-bending) breakthrough, in the form of the first synthesized porous liquid. The new material has the potential for a massive range of new technologies including carbon capture.
Scientists at the Georgia State University, Georgia Regents University and Charlie Norwood VA Medical Center found that the brain uses sweet foods to form the memory of a meal. The paper shows how the neurons in the dorsal hippocampus — a part of the brain that is critical for episodic memory — are activated by consuming sweets.
Women suffering from polycystic ovary syndrome (PCOS) show elevated levels of testosterone and testosterone derivatives in their systems, as well as an increased risk of anxiety and depression. As the offspring of these women (both sons and daughters) show similar symptoms, it’s been believed that PCOS can be transmitted through genetic code. However, a new idea comes to question this — specifically, the fact that the fetuses of mothers with PCOS are gestating in high levels of testosterone is what causes these symptoms.
For the first time, astronomers have detected primordial oxygen gassing out from a comet
When there’s rain, let alone a storm, city streets form puddles and in some extreme cases get flooded. That’s because concrete mostly keeps water out, and only a tiny volume gets absorbed. A company from the UK, however, has come up with such an innovative solution that it almost seems like magic were it not pure science at work. Namely, they came up with a new kind of concrete that allows more water to percolate through its gaps, so much that 1,056 gallons were gobbled up in under 60 seconds during a test. It all seems unreal – but it’s as concrete as it gets.
North Carolina State University researchers have succeeded in proving that the crystalline structure of a material can be formed by disorder at an atomic level and not chemical bonds, by creating the world’s first entropy-stabilized alloy incorporating oxides.
After they analyzed more than 2,000 traditional Indian recipes down to the molecular levels, scientists now think they know what makes Indian cuisine so appealing. Unlike western dishes, Indian recipes are based on ingredients whose flavors don’t overlap for a unique taste that dumbstrucks anyone who tries it for the first time.
Middle Age Europe was a place ruled by superstition and mythical beliefs – at least some parts of it were. Now, researchers are trying to figure out what made some people in Poland believe there was an ‘outbreak of vampires’ in the 17th and 18th century.
What happens when you mix the physical properties of glass (brittle and flowing) and metal (stiff and tough)? You get metal glass, of course. Since the 1960s, scientists showed you can make certain alloys into metal glass by rapidly cooling them. Really, really fast. Hundreds of degrees in a fraction of a second. Eventually you end up with an alloy that both behaves like a metal and glass. Some are three times stronger than titanium and have the elastic modulus of bone, all while being extremely lightweight. They’re also a lot more easy to machine than metals. All in all, metal glass is amazing and has the possibility to transform the world, just like another wonder material: graphene. So, why aren’t we seeing more of it? Part of the problem is that research is moving painfully slow, but this may set to change after a team of researchers in Sydney reported a model for the atomic structure of metal glass. If until now scientists were testing various alloys and technique in the dark, by trial and error, now they have a cook book for metal glass.
This fashionable triangle-shaped glassware isn’t an office decoration, but a true vestige of the early analytical chemistry. It’s called the kaliapparat, a hollow glass tubular device used to measure carbon content in substances in 1830 by German chemist Justus Liebig, widely considered the father of organic chemistry.After it first appeared, because it was so reliable, it spread throughout labs in Europe and North Africa within a matter of years. Look at this device again. Does it look familiar? It’s none other than the American Chemical Society’s logo – the same logo still in use today more than a century later. As such, the kaliapparat is one of the most important chemistry vessel and analytical tool in history. It’s also one of the most obscure. Few chemists know about it. Most ACS members have no clue what it is or what the logo means for that matter.
