Χρησιμοποιώντας σαν μοντέλο την δροσόφιλα (Drosophila melanogaster) μια νέα μελέτη εικονογραφεί τον τρόπο με τον οποίο δύο πρωτεΐνες λειτουργούν σαν μαέστροι δίνοντας συνθήματα κατά τη διάρκεια των πολύ πρώιμων σταδίων της ανάπτυξης της φρουτόμυγας.
The results of their research, reported Aug. 22 in Neuron, reveal that TMC1, a protein discovered in 2002, forms a sound- and motion-activated pore that allows the conversion of sound and head movement into nerve signals that travel to the brain—a signaling cascade that enables hearing and balance.
Tiny robots need not fear obstacle courses in the future: Scientists from the Max Planck Institute for Intelligent Systems in Stuttgart have developed a minuscule, flexible robot that can master a variety of forms of movement. Its magnetic drive allows it to walk, crawl and roll through difficult terrain. Moreover, it can transport small loads and swim on and in liquids. In future, tiny robots moving in this way could transport medication specifically to where it is needed._ Max Planck Gesellschaft.
EPFL mathematician Alfio Quarteroni and his team are building a virtual heart model based on personalized medical images that may one day help cardiologists and cardiac surgeons non-invasively diagnose pathological heart conditions. The team recently modeled and simulated the behavior of a patient’s aortic valve._EPFL
Scientists at King’s College London have developed a blood test that accurately and reliably predicts whether depressed patients will respond to common antidepressants, which could herald a new era of personalised treatment for people with depression._ King’s College of London
In a cutting-edge treatment for Alzheimer’s disease, EPFL scientists have developed an implantable capsule that can turn the patient’s immune system against the disease._EPFL
Scientists at the University of Cambridge have for the first time shown that it is possible to derive from a human embryo so-called ‘naïve’ pluripotent stem cells – one of the most flexible types of stem cell, which can develop into all human tissue other than the placenta.__The University of Cambridge
An analysis of data from two major, long-term epidemiologic studies finds that the regular use of aspirin significantly reduces the overall risk of cancer, a reduction that primarily reflects a lower risk of colorectal cancer and other tumors of the gastrointestinal tract. __MGH News
Hebrew University researchers develop a solution for long-term preservation of cells and organs for transplant, as part of a global alliance to bank organs__The Hebrew University of Jerusalem
This isn’t new technology – the first animal EEG was published a century ago – but computational neuroscientist Chennu has come up with a way of combining its output with a branch of maths called graph theory to measure the level of a person’s consciousness. What’s more, he’s developing the technology as a bedside device for doctors to diagnose patients suffering from consciousness disorders (such as a vegetative state caused by injury or stroke) to work out the best course of action and to support family counselling._ The University of Cambridge
A new genetic test to improve diagnosis in people with inherited heart conditions has been developed by researchers

In patients with heart failure, the pumping power of the heart decreases in a fatal downward spiral. Pharmacologists at ETH Zurich and the University of Zurich have now succeeded in breaking this vicious circle in the mouse model. Their approach could one day also benefit humans
