Graphene could help boost broadband internet speeds

Graphene, the strongest material on Earth, could help boost broadband internet speed, say UK researchers.

Scientists from Manchester and Cambridge universities, have found a way to improve its sensitivity when used in optical communications systems.

Their discovery paves the way for faster electronic components, such as the receivers used in fibre optic data connections.

Graphene was discovered in 2004 and has been hailed as a wonder material — via redwolf.newsvine.com

Split-Minded about Smoking

However, in my time studying, discussing, and thinking about these issues, I came across a new horn of the dilemma. I discovered that the severely mentally ill members of our country are smokers in massive numbers. For example, more than 80% of schizophrenics are smokers (some studies show numbers as high as 95%). The self-reported reasons for smoking by schizophrenics are the same as those for the general population: relaxation and habit. However, there has been a growing body of evidence, which many have now termed proof, that schizophrenics are using cigarette smoking as a means of self-medication — via redwolf.newsvine.com

Stanford researchers invent sutureless method for joining blood vessels

Reconnecting severed blood vessels is mostly done the same way today — with sutures — as it was 100 years ago, when the French surgeon Alexis Carrel won a Nobel Prize for advancing the technique. Now, a team of researchers at the Stanford University School of Medicine has developed a sutureless method that appears to be a faster, safer and easier alternative.

In animal studies, a team led by Stanford microsurgeon Geoffrey Gurtner, MD, used a poloxamer gel and bioadhesive rather than a needle and thread to join together blood vessels, a procedure called vascular anastomosis. Results of the research were published online 28 August in Nature Medicine. Lead authors of the study were postdoctoral scholar Edward Chang, MD, and surgery resident Michael Galvez, MD — via redwolf.newsvine.com

Scientists Claim New Map of Spiralling Light to Boost Fibre Optic Broadband Speed

Scientists working at the Institute of Ultrafast Spectroscopy and Lasers (IUSL), which is part of the City College of New York (CUNY), have discovered a new way of mapping spiralling light that could allow telecommunications operators the ability to harness untapped data channels” within fibre optic broadband ISP cables — via redwolf.newsvine.com

Underground river discovered below Amazon

A huge underground river appears to be flowing thousands of feet beneath the Amazon river, Brazilian scientists said Thursday.

Valiya Hamza of Brazil’s National Observatory said researchers found indications the subterranean river is 3,700 mileslong, about the same length as the Amazon on the surface — via redwolf.newsvine.com

Doing away with the dentist’s drill by helping teeth regenerate themselves

The fear of having a mechanical drill crammed into one’s mouth is enough to keep many people from regularly seeing a dentist. New technology developed by researchers at the University of Leeds that is based on knowledge of how the tooth forms in the first place could soon be providing a pain-free way of tackling the first signs of tooth decay. It uses a peptide-based fluid that is literally painted onto the damaged tooth’s surface to stimulate the tooth to regenerate itself.

The fluid developed by researchers in the University of Leeds’ School of Chemistry contains a peptide known as P 11-4 that will assemble into fibres under certain conditions. When applied to a tooth, the fluid seeps into the micro-pores that form when the acid produced by bacteria in plaque dissolves the mineral in the teeth — via redwolf.newsvine.com

Copper Pipe Magnet

The neodymium magnets are super powerful and even though they are not attracted to the copper, they still produce eddy currents that buffer the fall as seen in the video. Lenz’s Law make a great experiment for kids to adult. Also, great at parties when conversation goes stale

New Pacific eel is a living fossil, scientists say

A new type of eel that inhabits an undersea cave in the Pacific Ocean has been dubbed a living fossil because of its primitive features.

It is so distinct, scientists created a new taxonomic family to describe its relationship to other eels.

The US-Palauan-Japanese team say the eel’s features suggest it has a long and independent evolutionary history stretching back 200m years.

Details appear in the journal Proceedings of the Royal Society B — via redwolf.newsvine.com

Donors help to reboot US listening post for aliens

A California institute plans to reboot its listening post for intelligent life in space, with private donations to replace government cutbacks.

Back in April, the Search for Extraterrestrial Intelligence (SETI) Institute was forced to shut down its $30 million radio telescope array, designed to hear potential signals from alien life forms, for lack of funds.

But officials with the nonprofit institute in northern California’s Mountain View appealed for donations. This week, they said the total raised had surpassed their $200,000 goal.

That was due to the generosity of more than 2,400 donors, including actress Jodie Foster and Apollo 8 astronaut Bill Anders, they said — via redwolf.newsvine.com

Our brains aren’t built to understand altitude

Animal brains, ours included, have evolved to be powerfully aware of where we are at any given moment. But it turns out that our brains are surprisingly, frustratingly two-dimensional, and that we’re only dimly aware of changes in altitude.

That’s the finding of new research from University College London. The team studied specific brain cells as rats moved through space: grid cells, which are used to measure distance, and place cells, which are used to understand location. When the rats moved upwards in altitude on little spiral staircases and climbing walls, the researchers found that the grid cells didn’t respond at all, and the place cells only barely registered. This indicates that animal brains simply do not have the complexity to handle full three-dimensional awareness, and so we shortchange our knowledge of height in order to better navigate horizontally — via redwolf.newsvine.com
