Scientists Claim New State of Matter Created
Scientists claim to have created a form of aluminum that's nearly transparent to extreme ultraviolet radiation and which is a new state of matter. It's an idea straight out of science fiction, featured in the movie "Star Trek IV." The work is detailed in the journal Nature Physics....... |

More holes found in Web's SSL security protocol
IDG News Service - Security researchers have found some serious flaws in software that uses the SSL (Secure Sockets Layer) encryption protocol used to secure communications on the Internet. At the Black Hat conference in Las Vegas on Thursday, researchers unveiled a number of attacks that could be used to compromise secure traffic travelling between Web sites and browsers. This type of attack could let an attacker steal passwords, hijack an on-line banking session or even push out a Firefox browser update that contained malicious code, the researchers said.--- |

'Bald' bird a first for Asia in 100 years
HANOI -- A "bald" bird discovered in Laos is Asia's first new species of bulbul -- a type of songbird -- in more than 100 years, the Wildlife Conservation Society (WCS) said Thursday. Scientists from the Society, as well as the University of Melbourne, identified the bird, which has a practically bald head, WCS said in a news release. They reported their findings in the July issue of Forktail, the scientific journal of the Oriental Bird Club, a United Kingdom charity.... This undated handout picture received from the Wildlife Conservation Society shows a "bald" bird newly discovered in Laos' Savannakhet province. |

Homeless Man Leaves Behind Surprise: $4 Million
Every day on NPR, listeners hear funding credits — or, in other words, very short, simple commercials. A few weeks ago, a new one made it to air: "Support for NPR comes from the estate of Richard Leroy Walters, whose life was enriched by NPR, and whose bequest seeks to encourage others to discover public radio." NPR's Robert Siegel wondered who Walters was. So Siegel Googled him. An article in the online newsletter of a Catholic mission in Phoenix revealed that Walters died two years ago at the age of 76. He left an estate worth about $4 million. Along with the money he left for NPR, Walters also left money for the mission. But something distinguished Walters from any number of solvent, well-to-do Americans with seven-figure estates: He was homeless... You can listen to some of this story here ( link ) |

'Taste test' for Neanderthal DNA
DNA analysis of ancient remains shows that Neanderthals shared with modern humans the gene that gives the ability to taste bitter flavours. Most people find the chemical, known as PTC, very bitter, but 25% cannot taste it at all. The two groups have different taste receptors on their tongues. Analysis of the 48,000 year-old bone shows that the genetic variation responsible for this difference also existed in Neanderthals.... |

This compound is now known as Ataluren. About 50 years ago, at a postgraduate seminary, the registrar handed round a tube of Phenylthiocarbamide and, like Arthur Fox, who discovered this anomaly, I was unable to taste it, while all the other medicos found it disgusting.

U.S. Population Distribution by Age, 1950 through 2050
An animated chart that shows t U.S. population distribution by age from 1950 to 2050, which could be helpful in figuring out when health care expenses might rise sharply From the author As I follow up to my post Sunday, Health Care Spending and PCE, here is an animation of the U.S population distribution, by age, from 1950 through 2050. The population data and estimates are from the Census Bureau. Note: the third graph (link) is a Dynamic Population Pyramid of the same data from the Census Bureau. Watch for the original baby bust preceding the baby boom. Those are the people currently in retirement. With the original baby bust now at the age of peak health care expenses, these are the best of times (from a demographics perspective) for health care. Animation updates every 2 seconds. |

Traffic noise could be ruining sex lives of frogs
Traffic noise could be ruining the sex lives of urban frogs by drowning out the seductive croaks of amorous males, an Australian researcher said Friday. A well-projected and energetic croak is the male frog's most important asset in the quest to attract mates to his pond, Melbourne University ecologist Kirsten Parris said. But competition from traffic noise in Melbourne could be a reason why frog numbers have declined in Australia's second-largest city since her survey of more than 100 ponds began in 2000, she said.... In this undated photo, a Southern Brown Tree Frog sits on a log in swampy lands near Melbourne, Australia. ![]() |

Single molecule's stunning image
The detailed chemical structure of a single molecule has been imaged for the first time, say researchers. The physical shape of single carbon nanotubes has been outlined before, using similar techniques - but the new method even shows up chemical bonds. Understanding structure on this scale could help in the design of many things on the molecular scale, particularly electronics or even drugs. The IBM researchers report their findings in the journal Science. It is the same group that in July reported the feat of measuring the charge on a single atom... ![]() |

Is quantum mechanics messing with your memory?
![]() A physicist has claimed that glass can un-break – but quantum entanglement prevents our brains from recording the event For all we know we may live in a world in which windows un-break and cold cups of coffee spontaneously heat up, we just don't remember. The explanation is quantum entanglement... |
