The Importance of Hydration

In all organisms, water’s pH has a profound effect. Because the interaction of carbon dioxide and water explains the natural acidity of water and all accompanying reactions, it is considered a vital reaction by scientists. Researchers recently made a discovery about how dissolved dioxide bonds.

Antimatter Catches a Wave at SLAC

A study led by researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and the University of California, Los Angeles has demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons. The method may help boost the energy and shrink the size of future linear particle colliders – powerful accelerators that could be used to unravel the properties of nature’s fundamental building blocks.

New Data From Antarctic Detector Firms Up Cosmic Neutrino Sighting

Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos. The evidence is important because it heralds a new form of astronomy using neutrinos, the nearly massless high-energy particles generated in nature’s accelerators: black holes, massive exploding stars and the energetic cores of galaxies.

‘Diamonds From the Sky’ Approach Turns CO₂ Into Valuable Products

article637961.image1.jpg

Finding a technology to shift carbon dioxide (CO2), the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream. Now, a team of chemists says they have developed a technology to economically convert atmospheric CO2 directly into highly valued carbon nanofibers for industrial and consumer products. They will present the research at the 250th National Meeting & Exposition of the American Chemical Society.

Better-Tasting Grocery Store Tomatoes Could Soon Be on Their Way

Tomato lovers rejoice: Adding or rearranging a few simple steps in commercial processing could dramatically improve the flavor of this popular fruit sold in the grocery store, according to researchers. They will present their new work on the topic in Boston at the 250th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

Change in Process of Disinfecting Spinach, Salad Greens Could Reduce Illness Outbreaks

Cross contamination in commercial processing facilities that prepare spinach and other leafy greens for the market can make people sick. But researchers are reporting a new, easy-to-implement method that could eliminate or reduce such incidences. The scientists will present their work at the 250th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

New Technology Can Expand LED Lighting, Cutting Energy Use and Greenhouse Gas Emissions

article637649_1.jpg

Highly efficient, light-emitting diodes (LEDs) could slash the world’s electricity consumption. They are already sold in stores, but are expensive, and many of them give off “harsh” light. But researchers will report today that they have developed a less expensive, more sustainable white LED with a warm glow. The scientists will discuss their research at the 250th National Meeting & Exposition of the American Chemical Society.
