Chemistry

Want to off someone but you are ethically against using anything made by Monsanto?
How lifeless materials became organic molecules that are the bricks of animals and plants is a science question for the ages.

Because government mandates and subsidies for ethanol have caused grain prices to increase, pig farmers have instead looked for alternatives. One of those is distillers dried grains with solubles (DDGS), a co-product of ethanol that has expanded along with that industry.

But it is an evolving feed and some believe that unsaturated fatty acids in distillers dried grains leads to increased oxidation, which affects texture, color, juiciness and the overall flavor of pork products, and therefore the shelf life.  Some producers believe they can counteract that by feeding pigs saturated fats which will undo the fat-softening effects of DDGS. Firmer fat means longer-lasting pork. 

 By simply manipulating chemical gradients in a beaker of fluid, researchers have been able to create delicate flower structures -  not at the scale of inches, but microns.

These minuscule sculptures don't resemble the cubic or jagged forms normally associated with crystals, though that's what they are. Rather, fields of carnations and marigolds seem to bloom from the surface of a submerged glass slide, assembling themselves a molecule at a time.

The most powerful batteries on earth are only a few millimeters in size but a cellphone version can jump-start a dead car battery and then recharge the phone in the blink of an eye. 

Led by Professor William P. King, researchers at the University of Illinois at Urbana-Champaign show that the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics.

A traditional Balkan bedbug remedy has been shown stab and trap the biting insects, according to a paper in the Journal of the Royal Society Interface.

Just in time, too. Bedbugs have made a dramatic comeback in the U.S. in recent years, infesting everything from homes and hotels to schools, movie theaters and hospitals. Although not known to transmit disease, their bites can cause burning, itching, swelling and psychological distress. It helps to catch infestations early, but the nocturnal parasites' ability to hide almost anywhere, breed rapidly and "hitchhike" from place to place makes detection difficult. They can survive as long as a year without a blood meal.

New research hopes to create reactions necessary for industries such as pharmaceutical companies but eliminate the resulting waste from traditional methods. 

Traditional methods – dating back thousands of years – involve using solutions to speed up chemical reactions that are used to make products that we use every day. However, the leftover waste or solvents can often be a volatile compound.

Disposal and recycling is also becoming a growing and more costly challenge for companies as they follow increasing federal environmental regulations.

If objects from space kindled life on Earth, how did it happen?

The terrestrial or extra-terrestrial case for important ingredients that led to the building blocks of life is a hot debate. A new paper says that  adenosine triphosphate, similar to what is now found in all living cells and vital for generating the energy that makes something alive, could have been created when meteorites containing phosphorus minerals landed in hot, acidic pools of liquids around volcanoes, which were likely to have been common across the early Earth.

Bodily fluids contain lots of information about the health of people, that is why medical doctors routinely have blood and urine analyzed.

But bodily fluids can do more than mark infectious diseases or cancer and organ failure, researchers at ETH Zurich and at the University Hospital Zurich have shown they can take advantage of modern high-resolution analytical methods to provide real-time information on the chemical composition of exhaled breath.

Yes, your breath has an identifiable individual chemical pattern. Call it a a 'breathprint'?
