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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
