Dr. Stephen Barr, a researcher in the Department of Medical Microbiology & Immunology at the U of A, says his team identified a human gene called TRIM22 that can block HIV infection in a cell culture by preventing the assembly of the virus.
Barr says “interestingly, when we prevent cells from turning on TRIM22, the normal interferon response (a natural defense produced by our cells to fight infection by viruses such as HIV) is useless at blocking HIV infection. This means TRIM22 is an essential part of our body’s ability to fight off HIV.”
Barr’s team finds the results very exciting because it shows our bodies have a gene that is capable of stopping the spread of HIV. They are now trying to figure out why this gene does not work in people infected with HIV and if there is a way to turn this gene on in those individuals.
“We hope that our research will lead to the design of new drugs and/or vaccines that can halt the person-to-person transmission of HIV and the spread of the virus in the body, thereby blocking the onset of AIDS.”

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
