A miracle machine that cracks the code of life within hours and could revolutionise healthcare was the talk of Davos, grabbing the imagination of a forum otherwise shrouded in gloom.

Although robotic vacuum cleaners are still a relatively recent invention, they’re evolving quickly. After the SR8845 and SR8855, Samsung has launched the SR8895, which also goes by the name of ‘Silencio’. As you’d expect then, the main new feature of this vac is that it’s much quieter than the firm’s previous models.

While the prices of the two other models are now starting to come down, the SR8895 has launched with a rather extravagant £500 price tag!

Memories in our brains are maintained by connections between neurons called “synapses”. But how do these synapses stay strong and keep memories alive for decades? Neuroscientists at the Stowers Institute for Medical Research have discovered a major clue from a study in fruit flies: Hardy, self-copying clusters or oligomers of a synapse protein are an essential ingredient for the formation of long-term memory.

“We envision coupling a nanomechanical membrane to an electrical circuit so that an electrical signal, even if exceedingly faint, will cause the membrane to quiver slightly as a function of the strength of that signal,” said Jake Taylor, a physicist at the Joint Quantum Institute. “We can then bounce photons from a laser off that membrane and read the signal by measuring the modulation of the reflected light as it is shifted by the motion of the membrane. This leads to a change in the wavelength of the light.”

The technology could be used to significantly reduce the size of MRI machines by lowering the strength of signals needed, which would result in smaller magnets employed.

It could also be used to perform calculations that are currently impossible for existing computers, taking advantage of quantum physics to use light to transfer information among qubits. The system also automatically cools itself, which means that we won’t have to worry about the additional processing power leading to overheating.

Grape seed extract creates these conditions that are unfavorable to growth. Specifically, the paper shows that grape seed extract both damages cancer cells’ DNA (via increased reactive oxygen species) and stops the pathways that allow repair (as seen by decreased levels of the DNA repair molecules Brca1 and Rad51 and DNA repair foci).

“Yet we saw absolutely no toxicity to the mice, themselves,” Agarwal says.

Again, the grape seed extract killed the cancer cells but not the healthy cells.

“I think the whole point is that cancer cells have a lot of defective pathways and they are very vulnerable if you target those pathways. The same is not true of healthy cells,” Agarwal says.

True Knowledge is hoping the semantic database it has built up over the past few years could provide this edge.

Evi’s availability and promise as an artificial intelligence app, coupled with its low price (99 cents on the iPhone and free on Android phones), caused its popularity to skyrocket following its Monday release, and made it difficult for those downloading it to try it out. Evi isn’t the only Siri competitor—and in fact its capabilities are somewhat different from Siri’s offerings—but plenty of smart-phone users, it seems, are eager for Evi’s help in particular.
…
Essentially, the app takes your spoken or typed question and uses its vast store of knowledge along with outside data from websites like Yelp to give pertinent answers. This is similar to how Siri works, but Apple’s assistant focuses more on accomplishing tasks, such as making calls, setting alerts, or dictating text messages, by working with the iPhone’s other apps. Evi does not do these things, but Tunstall-Pedoe says it will eventually be able to take on more tasks.

This virus infects bacteria, specifically, the common E. coli bacterium. Although Lambda isn’t dangerous to humans, the new research highlights how viruses are capable of evolving complex and potentially deadly new traits.

“We were surprised at first to see Lambda evolve this new function, this ability to attack and enter the cell through a new receptor – and it happened so fast,” explained MSU graduate student Justin Meyer.

“But when we re-ran the evolution experiment, we saw the same thing happen over and over.”

Eating chocolate could stave off bowel cancer, say scientists.

A study found having daily doses of cocoa reduced the risk of developing the disease.

It is the latest piece of research to highlight the health benefits of the cocoa bean, most of which is harvested in West Africa.
