Synaptic connectivity motifs contribute to memory storage and retrieval in hippocampus

Fri, 09/09/2016 - 3:17pm
The hippocampal CA3 region plays a key role in learning and memory. One of the most remarkable properties of the network is its ability to retrieve previously stored memories from incomplete or degraded versions, a phenomenon that is widely known as pattern completion. It is generally accepted that the synapses between CA3 pyramidal cells, the recurrent CA3-CA3 synapses, play a key role in pattern completion, but how this exactly works has remained enigmatic.

Are fitness trackers fit for security?

Fri, 09/09/2016 - 1:51pm
The popularity of fitness trackers is constantly growing. Worldwide, nearly 20 million of these devices have been sold in the first quarter of 2016. Many of them track via GPS the kilometers the user run, measure heart rate and pulse or check if the user is asleep. Now researchers reveal some serious security flaws in these devices.

Scientists expect to calculate amount of fuel inside Earth by 2025

Fri, 09/09/2016 - 1:48pm
Scientists have developed numerous models to predict how much fuel remains inside Earth to drive its engines -- and estimates vary widely -- but the true amount remains unknown. In a new article, a team of geologists and neutrino physicists boldly claims it will be able to determine by 2025 how much nuclear fuel and radioactive power remain in the Earth's tank.

Physicists discover 'smoke rings' made of laser light

Fri, 09/09/2016 - 1:48pm
Physicists have discovered that self-focused laser pulses generate violent swirls of optical energy that resemble smoke rings. In these light structures, known as 'spatiotemporal optical vortices,' light energy flows through the inside of the ring and loops back around the outside. The vortices travel with the laser pulse and control energy flow around it.

Dances with waves: Breakthrough in moving small objects using acoustics

Fri, 09/09/2016 - 1:48pm
Researchers have made a breakthrough in controlling the motion of multiple objects on a vibrating plate with a single acoustic source. By playing carefully constructed melodies, the scientists can simultaneously and independently move multiple objects on the plate towards desired targets. This has enabled scientists, for instance, writing words consisting of separate letters with loose metal pieces on the plate by playing a melody.

Three in four don't know obesity causes cancer

Fri, 09/09/2016 - 12:39am
Three out of four people in the United Kingdom are unaware of the link between obesity and cancer, according to a new report. The nationwide survey found that people from lower socioeconomic backgrounds are less likely to know about the link. And men are less likely than women to be aware of the increased risk of cancer caused by obesity.

Major review to help doctors, patients and public make informed decisions about the use of statins

Fri, 09/09/2016 - 12:39am
A major review of the available evidence on the safety and efficacy of statin therapy intends to help doctors, patients and the public make informed decisions about the use of the drugs. The authors warn that the benefits of statin therapy have been underestimated, and the harms exaggerated, because of a failure to acknowledge properly both the wealth of evidence from randomized trials and the limitations of other types of studies.
