Universities not only provide the ideal petri dish for cultivating bioscience with commercial potential, but have a moral obligation to do so, given the opportunity to translate public funding into health and jobs, according to a new case study by UCSF researchers.
In an analysis published Wednesday in Science Translational Medicine, researchers at the California Institute for Quantitative Biosciences
(QB3) assessed the impact of the institute’s efforts over the past
eight years in supporting entrepreneurs on the three UC campuses in
which it operates: UCSF, UC Berkeley and UC Santa Cruz.
The study found that, by lowering the hurdle even very slightly for
scientists to become entrepreneurs, the scientists were able to gain
extraordinary traction in translating academic research into public
benefit, generating 60 new companies in the first six years and
attracting 75 new bioscience...

Whitehead scientists identify major flaw in standard approach to global gene expression analysis
The assumption in traditional genetic expression analysis that mRNA
content is similar between cells (represented by orange and black dots)
does not affect the final results when the cells in fact do have
equivalent mRNA content, as in Figure A. In Figure B, the cell
represented by the orange dots has a significantly higher mRNA content,
but when the data is normalized with the assumption that their contents
are equal, the perceived response is skewed and inaccurately indicates
that some of the genes are repressed (green bars). Using a standardized
control, as in Figure C, eliminates the assumptions about mRNA content
and presents accurate results.
Whitehead Institute researchers report that common assumptions
employed in the generation and interpretation of data from global gene
expression analyses can lead to seriously flawed conclusions about gene
activity...

A new glow for electron microscopy
In this electron microscope image of a mitochondrion, the matrix has
been
stained with APEX, making it appear dark. The lighter
projections
into the matrix represent the intermembrane space.

The glowing green molecule known as green fluorescent protein (GFP) has
revolutionized molecular biology. When GFP is attached to a particular
protein inside a cell, scientists can easily identify and locate it
using fluorescence microscopy. However, GFP can’t be used with electron
microscopy, which offers much higher resolution than fluorescence
microscopy.
Chemists from MIT have now designed a GFP equivalent
for electron microscopy — a tag that allows scientists to label and
visualize proteins with unprecedented clarity.

may appear only a few pixels...

Scientists Pinpoint Key Player in Parkinson's Disease Neuron Loss
By reprogramming skin cells from Parkinson's disease patients with a known genetic mutation,
researchers at the Salk Institute for Biological Studies have identified damage to neural stem cells as a powerful player in the disease. The findings, reported online October 17th in Nature, may lead to new ways to diagnose and treat the disease.
The
scientists found that a common mutation to a gene that produce the
enzyme LRRK2, which is responsible for both familial and sporadic cases
of Parkinson's disease, deforms the membrane surrounding the nucleus of a
neural stem cell. Damaging the nuclear architecture leads to
destruction of these powerful cells, as well as their decreased ability
to spawn functional neurons, such as the ones that respond to dopamine.
The
researchers checked their laboratory findings with brain samples from
Parkinson's disease patients and found the same nuclear...

No Antibodies, No Problem
Researchers at the Johns Hopkins Bloomberg School
of Public Health have determined a new mechanism by which the
mosquitoes’ immune system can respond with specificity to infections
with various pathogens, including the parasite that causes malaria in
humans, using one single gene. Unlike humans and other animals, insects
do not make antibodies to target specific infections. According to the
Johns Hopkins researchers, mosquitoes use a mechanism known as
alternative splicing to arrange different combinations of binding
domains, encoded by the same AgDscam gene, into protein repertoires that
are specific for different invading pathogens. The researchers’
findings were published October 18 in the journal Cell Host & Microbe and could lead to new ways to prevent the spread of a variety of mosquito born illnesses.
Mosquitoes
and other insects use their primitive innate immune systems to
successfully fight infections with a broad spectrum of viruses,
bacteria, fungi and parasites, despite the lack of antibodies that are
part of the more sophisticated human immune system. The effectiveness of
the human immune system is to a large degree based on the ability to
produce an enormous variety of antibodies containing different
immunoglobulin domains that can specifically tag and label a pathogen
for destruction. This great variety of pathogen-binding antibodies is
achieved by combining different immunoglobulin gene segments and further
mutate them through mechanisms called somatic recombination and
hypermutation. While mosquitoes also have genes encoding immunoglobulin
domains, they lack these specific mechanisms to achieve pathogen
recognition diversity.

Caltech Modeling Feat Sheds Light on Protein Channel's Function
Chemists at the California Institute of Technology (Caltech) have
managed, for the first time, to simulate the biological function of a
channel called the Sec translocon, which allows specific proteins to
pass through membranes. The feat required bridging timescales from the
realm of nanoseconds all the way up to full minutes, exceeding the scope
of earlier simulation efforts by more than six orders of magnitude. The
result is a detailed molecular understanding of how the translocon
works.
The ribosome (red-blue) in complex with the translocon
channel (green)
which is embedded in the cell membrane
(yellow, white).
Proteins that are inserted via the
ribosome into the
channel
can either
be
laterally
integrated into the cell membrane or secreted across the
cell membrane
(inset).
Modeling behavior across very different timescales is a
major challenge in modern simulation research....

Eco-friendly Optics: Spider Silk’s Hidden Talents Brought to Light for Applications in Biosensors, Lasers, Microchips
Spiders use their silk to catch lunch. Now physicists are using it to
catch light. New research shows that natural silk could be an
eco-friendly alternative to more traditional ways of manipulating light,
such as through glass or plastic fiber optic cables. Two teams
independently exploring possible applications for the material’s
photonic talents will present their latest breakthroughs at the Optical
Society's (OSA) Annual Meeting, Frontiers in Optics (FiO) 2012, to be held next week in Rochester, N.Y.

make use of silk’s optical properties for implantable sensors and other
biology-technology interfaces.

University of Washington researchers focus on quorum sensing to better understand bacteria
The relatively new field in microbiology that focuses on quorum
sensing has been making strides in understanding how bacteria
communicate and cooperate. Quorum sensing describes the bacterial
communication between cells that allows them to recognize and react to
the size of their surrounding cell population. While a cell's output of
extracellular products, or "public goods," is dependent on the size of
its surrounding population, scientists have discovered that quorum
sensing, a type of bacterial communication, controls when cells release
these public goods into their environments.
In a study appearing in the Oct. 12 issue of the journal Science, University of Washington researchers examine the pathogen Pseudomonas aeruginosa,
which colonizes in the lungs of cystic fibrosis patients. While most
cells "cooperate" with each other by producing and sharing public goods
when...
