A Washington State University study of the chemistry of technetium-99 has improved understanding of the challenging nuclear waste and could lead to better cleanup methods.
Catnip is notorious for its euphoric effects on our feline companions. What is it about catnip that makes cats go nuts, and what benefit does this have for the plants? The secret may be a chemical that has more to do with six-legged creatures than our four-legged friends. Watch the latest Speaking of Chemistry video here: https://youtu.be/G-XUpY82S18.
Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an 'enormous Lyman-alpha nebula' (ELAN), it is the brightest and among the largest of these rare objects, only a handful of which have been observed.
In a recent paper, Joel Eissenberg, Ph.D., professor of biochemistry and molecular biology at Saint Louis University, explores questions that stem from new advances in direct-to-consumer DNA tests, which have the effect of separating the physician-patient relationship from access to new personal health data.
After a 12-day flight spent examining solar flares while tethered from an enormous balloon, the GRIPS telescope endured a one-year layover alone on the Antarctic snowscape before scientists could retrieve their hardware.
Pulse lasers built entirely on optical fibers are increasingly readily being used by industry. Optical scientists from the Warsaw Laser Centre of the Institute of Physical Chemistry of the Polish Academy of Sciences and the Faculty of Physics of the University of Warsaw have generated ultrashort laser pulses in an optical fiber, by using a method previously considered as physically impossible to achieve. Their solution is not only useful, but also surprisingly simple!
The New Horizons flyby of Pluto and its satellites returned a scientific treasure trove of information about these distant and surprisingly complex worlds, showing a vast nitrogen glacier as well as ice mountains, canyons, cliffs, craters and more. Now the categories for official names have been approved and the name proposals can be submitted by the New Horizons team.
A heel-down posture -- a feature that separates great apes, including humans, from other primates -- confers advantages in fighting, according to a new study published today in the journal Biology Open.
With sustainable solutions in mind, a new study published by eminent physicist Jo Hermans in MRS Energy and Sustainability--A Review Journal (MRS E&S) looks at the energy efficiency of current modes of transportion.
Researchers from the Basque institutions CIC nanoGUNE, Ikerbasque and Cidetec, and the German Robert Koch-Institut report the development of hyperspectral infrared nanoimaging. It is based on Fourier transform infrared nanospectroscopy (nano-FTIR) and enables highly sensitive spectroscopic imaging of chemical composition with nanoscale spatial resolution.
