His
DNA had been decoded; samples from his stomach and intestines have
allowed us to reconstruct his very last meal. The circumstances of his
violent death appear to have been explained. However, what had, until
now, eluded scientists was identifying any traces of blood in Ötzi, the
5,000 year old glacier mummy.

A
new Agriculture Department program will begin tracing the source of
potentially contaminated ground beef as soon as there is an initial
positive test. Current procedures require USDA officials to wait until
additional testing confirms E. coli before starting
their investigation. Under the new process, the source could be traced
24 to 48 hours sooner.

Protein
folding is the process by which not-yet folded chains of amino acids
assume their specific shapes and functions. At these sizes, friction
becomes an all-important factor in the way proteins form, slowing down
the arrangement of amino acids. Now, researchers in California are
finding that internal friction may actually result in unfolded or
misfolded proteins.

Small-angle
neutron scattering instrument at the High Flux Isotope Reactor at Oak
Ridge National Laboratory can be used for a surprising variety of
biological studies. Recently, researchers in The Netherlands
successfully analyzed and characterized the internal protein structure
and composite particles of a cow named Martha.

Plants
that contain the ingredients for the popular licorice treat employ a
complex assembly line of enzymes to produce the glycyrrhizin molecule, a
potent sweetener that is also an effective anti-inflammatory and
antiviral agent. A newly discovered enzyme brings scientists one step
closer to understanding how plants like licorice root manufacture a
molecule with potent medicinal properties.

The
conventional image about the inside of the brain is that it resembles a
bowl of spaghetti noodles. A research team say they have now discovered
that a more uniformed grid-like pattern makes up the connections of the
brain, and the pathways can be described as woven sheets of fiber
running two directions.

From
an extensive study that grew out of an initial research cruise to the
Gulf of Mexico in October 2010, scientists have published the first
evidence of the impact of the Deepwater Horizon oil spill on deep-sea
corals. The team used underwater vehicles and 2D gas chromatography to
determine precisely the source of the petroleum hydrocarbons they found.

After
a year in Asia and South America visiting labs that lacked the basics,
University of California, Berkeley’s Lina Nilsson and a team of
engineering colleagues realized they could develop low-cost, accessible
tools that could produce research-grade results. The team has evolved
into Tekla Labs, which creates protocols for do-it-yourself laboratory
equipment.

Researchers
in Japan have built a multimodal bio-image sensor that can render
images of the 2D distribution of proton concentration (pH) and
fluorescence intensity for multimodal analyses of biochemical objects.

“Rolling”
is a common mechanism cells use to navigate through the body. White
blood cells, for example, roll along a blood vessel’s walls to reach
inflamed areas. A team of biotechnology experts have invented a
microfluidic device that uses this natural cell-rolling mechanism to
sort cells. The device features tiny channels coated with sticky
molecules that bind weakly with certain cells, forcing them to roll into
a different spot.
