Research idea for the treatment of Alzheimer's disease

Little presentation for the research idea for the treatment of Alzheimer's disease, which is a degenerative process of the brain.

Memory improvement through electrical shock; Research

Researchers have published in The New England Journal of Medicine that memory of the epileptic patients improved after slight electrical shock.

Researchers focused on the entorhinal cortex - part of the brain helpful in the formation and storage of memories - and hippocampus that is the brain's chief memory center.

"When we stimulated the hippocampus itself, there was not an effect. It was really stimulation in the gateway to the hippocampus - the entorhinal cortex - where we got the beneficial effect in terms of memory," Dr. Itzhak Fried, professor of neurosurgery at the David Geffen School of Medicine at UCLA, who worked on the study, said.

According to researchers, this can be of help for the patients of Alzheimer's disease.

Fourth quarter results by Sprint Nextel

“Our strong fourth quarter performance illustrates the power of matching iconic devices like the iPhone with our simple, unlimited plans and industry-leading customer experience,” said Dan Hesse, Sprint CEO, who is hopeful about the future of the company. “During the past year, Sprint added more than 5 million net new customers and grew wireless service revenue by more than 5 percent, including 17 percent for the Sprint platform.

DDoS attacks on the rise

According to DDoS mitigation companies, Prolexic and Arbor Networks, distributed denial-of-service (DDoS) attacks are on the rise. According to the reports by the companies, so-called layer-7 DDoS attacks have been increased especially targeting Internet facing applications.


From SayPeople,

Prolexic has reported 45% increased DDoS attacks in Q4 of the last year. That is double than the number of attacks in the third quarter of the year 2011. 

Paul Sop, Prolexic's chief technology officer, reported that there is shorter attack duration with bigger packer-per-second attack volume. Average attack bandwidth in Q4 2011 was 5.2Gbps (bits per second), 148 percent higher as compared to the third quarter. This is 136% increase on annual basis.

“We have seen a trend toward shorter overall attack duration, but with unprecedented high packet-per-second volume and lethal attack signatures,” said Sop. “This is a devastating cocktail that can quickly bring down even well protected sites and their mitigation providers. We are starting to see packet-per-second attack volumes that are simply off the charts.”
