Chemists develop simple technique to visualize atomic-scale structures

Chemists develop simple technique to visualize atomic-scale structures

Researchers at the California Institute of Technology (Caltech) have devised a new technique—using a sheet of carbon just one atom thick—to visualize the structure of molecules. The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a potentially unlimited number of other molecules, including antibodies and other biomolecules.

New self-assembling photovoltaic technology can keep repairing itself

New self-assembling photovoltaic technology can keep repairing itself

Plants are good at doing what scientists and engineers have been struggling to do for decades: converting sunlight into stored energy, and doing so reliably day after day, year after year. Now some MIT scientists have succeeded in mimicking a key aspect of that process.

Near infrared light may open new frontier in fighting cancer

Near infrared light may open new frontier in fighting cancer

A “game-changing” technique using near infrared light enables scientists to look deeper into the guts of cells, potentially opening up a new frontier in the fights against cancer and many other diseases. University of Central Florida chemists used near infrared light and fluorescent dye to take pictures of cells and tumors deep within tissue.

Making phosphorus safer

Making phosphorus safer

A MIT team has developed a new way to attach phosphorus to organic compounds by first splitting the phosphorus with ultraviolet light. Their method eliminates the need for chlorine, which is usually required for such reactions and poses health risks to workers handling the chemicals.

New Mountain Capital completes acquisition of Mallinckrodt Baker

A New York-based private equity firm has announced the completion of its acquisition of Mallinckrodt Baker, Inc. from Covidien for approximately $280 million. The New Jersey-based chemical manufacturer will continue operations as usual, according to the new owner, but the company must drop the Mallinckrodt name.

DNA code of the Golden Delicious apple sequenced for the first time

The DNA code of the Golden Delicious apple has been sequenced for the first time by a global team of 86 scientists from Italy, France, New Zealand, Belgium, and the United States. The breakthrough could help agricultural scientists selectively breed new apple varieties that have desired traits and that are more resistant to disease and drought.

Chloride binder functions like a light switch

Chloride binder functions like a light switch

Chemists at Indiana University Bloomington have designed a molecule that binds chloride ions, but can also be conveniently compelled to release the ions in the presence of ultraviolet light. The mechanism relies on a custom folding molecule and a polymer, and will eventually be adapted for use in a water-based system rather than the current organic-based solution.

Potential cancer drug arises from sponges

Potential cancer drug arises from sponges

Deep in the ocean, sponges of the Agelas family emit chemicals believed to help them defend their territory. Those chemicals, called agelastatins, have also shown the ability to kill cancer cells. For that reason, chemists have been trying to find ways to synthesize agelastatins in the laboratory since the chemicals were discovered in 1993. Now, chemists at MIT recently discovered the shortest and most productive way to synthesize all six of the known agelastatins.

Stretched molecule snaps back smaller than started

Stretched molecule snaps back smaller than started

Crazy bands are cool because no matter how long they've been stretched around a kid's wrist, they always return to their original shape, be it a lion or a kangaroo. Now a Duke and Stanford chemistry team has found a polymer molecule that's so springy it snaps back from stretching much smaller than it was before.

A better method for cultivating stem cells

A better method for cultivating stem cells

MIT chemical engineers, materials scientists, and biologists have devised a synthetic surface that includes no foreign animal material and allows stem cells to stay alive and continue reproducing themselves for at least three months. It’s also the first synthetic material that allows single cells to form colonies of identical cells, which is necessary to identify cells with desired traits and has been difficult to achieve with existing materials.

The irresistability of the end

The irresistability of the end

What is it about doomsday scenarios? Every once in a while, it seems, the general public can’t get enough of predictions about impending disaster. And the most recent spate of disaster ruminations seems more pervasive than ever.

Premature death notice

Premature death notice

Earlier this week, Wired editor Chris Anderson declared the death of the Web and the rise of everything else (on the Internet). It was a bit like twittering the death of your favorite celebrity on Twitter, except in this case it’s the one loved by billions.
