Over the years, computer chips have gotten smaller, thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore’s Law. But there’s one component of the chip-making process in need of an overhaul if Moore’s law is to continue: the chemical mixture called photoresist.

Researchers at The University of Tennessee are a step closer to creating a prophylactic drug that would neutralize the deadly effects of the chemical weapons used in Syria and elsewhere. Jeremy Smith, UT-ORNL Governor’s Chair and an expert in computational biology, is part of the team that is trying to engineer enzymes — called bioscavengers — so they work more efficiently against chemical weapons.
Every day thousands of people around the world have their lives saved or improved thanks to someone giving blood. But imagine how many more lives could be saved if a long-lasting blood substitute could be found, which could easily be stored at room temperature and available to all patients, regardless of their blood type. This is the challenge a team of scientists at the University of Essex are hoping to overcome with their Haem02 project
Like a Formula One race car stuck in a traffic jam, HPC hardware performance is frequently hampered by HPC software. This is because some of the most widely used application codes have not been updated for years, if ever, leaving them unable to leverage advances in parallel systems. As hardware power moves toward exascale, the imbalance between hardware and software will only get worse. The problem of updating essential scientific ...
Alexander Shulgin, a respected chemist famed for dusting off a decades-old recipe for the psychedelic drug ecstasy, died June 2, 2014, at his Northern California home. He was 88. Shulgin's wife, Ann, said liver cancer was the cause. She said he had been diagnosed about a year ago and was surrounded by family and friends when he died at "the farm," his sprawling residence and lab in a remote part of Lafayette, CA
LEGO has announced that a female minifigure set, featuring three scientists along with their lab gear, will be released as the next LEGO Ideas set. This “Research Institute” model is an official set of all-female scientist figures — a paleontologist, an astronomer and a chemist — made with regular LEGO minifigures.
Nine scientists won awards May 29, 2014, for theories about the first moments of the universe, discoveries about the brain and techniques to let researchers see ever-tinier things. The winners, announced by the Norwegian Academy of Science and Letters, will share three $1 million Kavli Prizes. Awarded biennially since 2008, the prizes are named after philanthropist Fred Kavli, a native of Norway. Kavli died last November.
Dassault Systèmes, a 3-D design software company, has announced the introduction of its newest brand, BIOVIA. The new brand is a combination of Dassault Systèmes’ own activities in BioIntelligence, its collaborative 3DEXPERIENCE technologies, and the life sciences and material sciences applications from the recent acquisition of Accelrys.
It’s the sort of thing you would expect Dr Who to do – join up someone’s damaged nerves by using a sonic screwdriver. But the scientists at the University of Glasgow are no time-travellers and their work is based in a lab — not a Tardis. Their research shows that cell patterning using a specific kind of sonic screwdriver — a Heptagon Acoustic Tweezer — may soon be in a position to deliver important results.
The stage is set for a new, super-heavy element to be added to the periodic table following research published by a multinational team of physicists and chemists. The team created atoms of element 117, matching the heaviest atoms ever observed, which are 40 percent heavier than an atom of lead.
The Vortex data analysis and visualization tool is designed for scientists working in the areas of chemistry, biology and engineering. It is compatible with the credit-card sized computer Raspberry Pi, as well as Windows, Mac OS X and Linux, offering an alternative to spreadsheets and providing the plots and functionality required by scientists to explore and understand large sets of complex data.
Scientists are using powerful analytical and imaging tools to study artworks from all ages, delving deep below the surface to reveal the process and materials used by some of the world’s greatest artists. Chemist Richard Van Duyne, in collaboration with conservation scientists at the Art Institute of Chicago, has been using a scientific method to investigate masterpieces by Pierre-Auguste Renoir, Winslow Homer and Mary Cassatt.
Tens of thousands of pot smokers wheezed a sigh of relief when recreational marijuana use was made legal January 1, 2014. Gone is the cottage industry of gray-area physicians rubber-stamping medical prescriptions for a well-informed gaggle of would-be stoners who memorized popular conditions sure to garner approval.
Glaciers are commonly thought to work like a belt sander. As they move over the land they scrape off everything — vegetation, soil, and even the top layer of bedrock. So scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice.
Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet's living kingdoms. How did it all begin?

When life on Earth was first getting started, simple molecules bonded together into the precursors of modern genetic material. A catalyst would have been needed, but enzymes had not yet evolved. One theory is that the catalytic minerals on a meteorite’s surface could have jump-started life’s first chemical reactions. But scientists need a way to directly analyze these rough, irregularly shaped surfaces.

A unique method to collect rain water samples during Hurricane Sandy has revealed the storm's chemical "signature" with a new level of detail. The technique may also lead to weather model advances that will ultimately improve storm prediction. Hurricane Sandy, also known as Superstorm Sandy, was the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season. Nearly 300 people perished along the path of the storm.
This month’s review is a bit off of the usual track, e.g. statistical, mathematical and genomics software. However, it does include much pertinent information for chemists, chemical engineers and biologists. SciFinder is a search engine for chemistry and biology references for just about anything that can be accurately described in the search feature.
Astronomers at the University of Washington have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, scientists may one day use this same technique to detect its biosignature — the telltale chemical signs of its presence — in the atmosphere of an alien world.
The ACD/Spectrus Platform enables organizations to apply chemical context to their spectroscopy, spectrometry, and chromatography content by making it easier to manage unified analytical data from multiple techniques and instruments, and to combine it with chemical and structural information in a homogeneous environment.
