A brand new type of HIV vaccine will move onto phase II clinical trials in 2017, after phase I trials showed that it was safe to use in humans.

The potential new vaccine will be tested on 600 people in North America, to see how well it can prevent them from getting the virus.

Before we get too excited, the phase I trials were only set up to show that the vaccine was tolerated well by the human body — they didn’t demonstrate if it actually works as a preventative treatment.

Scientists hoping to get a glimpse of molecules that control brain activity have devised a new probe that allows them to image these molecules without using any chemical or radioactive labels.

Currently the gold standard approach to imaging molecules in the brain is to tag them with radioactive probes. However, these probes offer low resolution and they can’t easily be used to watch dynamic events, says Alan Jasanoff, an MIT professor of biological engineering.

Jasanoff and his colleagues have developed new sensors consisting of proteins designed to detect a particular target, which causes them to dilate blood vessels in the immediate area. This produces a change in blood flow that can be imaged with magnetic resonance imaging (MRI) or other imaging techniques.

Great.

Research published in Acta Neuropathologica, identified alterations in a protein known as ATRX in human brain tumours; researchers might also be able to target microRNAs directly, altering their levels to make cancer cells less likely to form tumours.

A recent study suggests that two recently discovered genetic differences between brain cancer cells and normal tissue cells could offer clues to tumour behaviour and potential new targets for therapy.

MIT researchers and their colleagues have developed a new computational model of the human brain’s face-recognition mechanism that seems to capture aspects of human neurology that previous models have missed.

The researchers designed a machine-learning system that implemented their model, and they trained it to recognize particular faces by feeding it a battery of sample images. They found that the trained system included an intermediate processing step that represented a face’s degree of rotation — say, 45 degrees from center — but not the direction — left or right.

A new strict cyber security policy sees US tech companies in a stand-off with the Chinese authorities.

Hmmmm.

Sam Gussman arrived four years ago at Stanford University hoping to eventually parlay an engineering degree into a product manager job at Google or Facebook.

Working for the National Security Agency or other intelligence bureaus never crossed his mind. For Gussman, the government didn’t seem like the place for the most exciting, cutting-edge research in human computer interaction — his area of interest. Plus, it did no on-campus recruiting, unlike the many tech startups that e-mailed him daily about job opportunities and happy hours.
