20. HHV-6 Virus May Enter Brain via Nose 'Say Experts'

HHV-6 Virus May Enter Brain via Nose 'Say Experts': Human herpes virus-6 (HHV-6), a member of the family of viruses that includes genital herpes as well as oral herpes, has been observed as the culprit for causing cold sores and often linked with various brain disorders, including multiple sclerosis, encephalitis and a form of epilepsy as well as causing roseola, a disease common among infants that results in high fever along with skin rashes.

Recently, experts at the Proceedings of the National Academy of Sciences have suggested that the common virus tends to slink into the brain through nose via nasal mucus and travels along olfactory cells right into the brain.

While explaining the findings of the study, Coauthor Steven Jacobson, of the National Institute of Neurological Disorders and Stroke in Bethesda, MD, claimed that everyone is exposed to this virus. In addition, Steven Jacobson also expressed disappointment that very little is known about the virus. Some studies have suggested that the virus may live in tonsils or in saliva. Further, other viruses such as herpes simplex, influenza A and rabies can invade the brain by shooting through the nose.

During the study course, researchers observed high levels of HHV-6 in the olfactory bulb, a smell-related part of the brain, in two of three autopsy brain samples. source

Facebook' Could Become Adults Only

Alarming ... according to cyber security expert Susan McLean, Facebook gossip sites have "exploded in the last two or three months".

Facebook' Could Become Adults Only - Ways to force Facebook to give parents access to their kids' profiles will be discussed today by state and federal attorneys-general in a meeting that will also examine an 18+ Facebook age limit.

The idea was first proposed by a South Australian Family First MP, Dennis Hood, and is being championed by South Australian Attorney-General John Rau. Rau argued that giving parents assistance to supervise their children on Facebook would help protect against online predators and limit access to unsuitable material.

But Susan McLean, who was Victoria Police's first cyber safety officer and is now an online safety consultant, said the proposal was “ill informed and it shows a total lack of understanding of what the internet is”.

“It's not Facebook's fault that there are problems on Facebook. You can't legislate against stupidity or poor parenting or anything like that,” said McLean.

“It would be nice but it can't be done and it breaks down any level of trust that you should be trying to develop with your kids.”

Facebook's terms of use currently requires users to be aged at least 13 but there is no proof of age requirement and kids regularly lie to gain access.

At their meeting today, the country's top lawmakers will consider requiring proof of age checks and even raising the age limit to 18, federal Attorney-General Robert McClelland confirmed.

This would be at stark odds with recent comments from Facebook founder Mark Zuckerberg, who floated the idea of removing the 13 minimum sign-up age policy.

“Age verification is something that various platforms deal with and I can't see why it should be beyond the wit of Facebook to do the same thing, if that was the solution people wanted,” said Rau.

“I think people need to understand that just because they are operating in the virtual world, that is on the internet, it does not mean that there should not be boundaries or rules or standards of behaviour.

“Exactly how these boundaries and rules should be applied and enforced is a matter that we need to discuss.”

It is unclear how the attorneys-general could apply such regulations to Facebook given it is a US-based company. Rau said changing the rules on access to Facebook would require cooperation from operators and the federal government would need to use its communications powers.

McClelland said yesterday it would be Rau's task to come up with methods of implementing the restrictions.

He said Rau made a fair point as “there has been concern expressed by some parents that the images being put up by their own children are prejudicial to their future career prospects”.

“I think that all Attorneys recognise it as a legitimate issue to raise and … John having raised it, will be tasked … to come back with a few suggested solutions,” said McClelland.

“Having Australian jurisdiction extend off shore is the challenge. That's not to say a bit of discussion can't get some goodwill. Hopefully we will be able to look at a few options.”

Asked whether the issue could be solved simply by parents sitting down with their children, rather than with new regulations, McClelland agreed that this would be a preferable approach.

“Having said that, I have four kids, not in every situation can we reach an accommodation so I can understand some parents have raised the issue,” he said.

But McLean said implementing the proposals would be impossible.

“Say we get this law that says parents are allowed to access their kids facebook accounts, how am I going to prove that I'm your mother?,” she said.

“It's totally unworkable because there is nothing on the internet that allows anyone to age and identity verify anyone, so that's where it's going to fall down in the first place.

“Secondly, American companies aren't necessarily obliged to obey Australian law. Thirdly, tech savvy kids will set up two accounts – here's the one mum can see and here's the one where I do whatever it is I wanna do on it.”

Stephen Collins, spokesman for the online users' lobby group Electronic Frontiers Australia, agreed with McLean that any restrictions would be difficult to enforce.

"We'd very much prefer a social and educational approach - teach people good privacy practice, make it easy for them, educate about acceptable behaviors (e.g. why should online behaviors be different in terms of what we accept from those in the physical world?)," he said.

"So too, a parental right to access that is any greater than exists in law now (such as access to medical details for 16-18 year olds) seems heavy-handed."

Comment is being sought from Facebook. The site counts about 10 million Australian users, or almost half the population.

At the meeting today the attorneys-general will also discuss whether to allow an R18+ rating for video games. The federal government is a vocal supporter of the change but has had difficulty convincing some states that it won't result in a stream of ultra-violent and sexualised games flooding the market.

Privacy is also on the agenda after the government raised the idea of a statutory right to privacy following the hacking scandal that has engulfed News Corporation.

Ways to deal with the online publication of suppressed legal material will also be discussed. Rau said it was clear that suppression orders – which prevent media from reporting details of court cases - were being undermined by social networking sites. ( Sydney Morning Herald/KOMPAS.com)

A 120-million-year-old fossil of a pregnant lizard has been found in China

A 120-million-year-old fossil of a pregnant lizard has been found in China: BBC reported Thursday. The fossil is a complete 30 cm lizard with over a dozen embryos in its body.

Researchers from University College London, who studied the fossil, say it was just days from giving birth when it died and was buried during the Cretaceous period. The findings were published in the journal Naturwissenschaften. The fossil is interesting to scientists because it is a reptile that produced live young rather than laying eggs.

Only 20 percent of living lizards and snakes produce live young, and this shows it is an ancient, if unusual, trait. “I didn’t think much of the fossil when I first saw it,” BBC quoted Susan Evans, joint lead author of the paper, as saying.

But when her colleague, Yuan Wang, from the Chinese Academy of Sciences, examined the fossil he spotted the tiny remains of at least 15 almost fully developed embryos inside it, it said. The fossil is so well preserved that the minuscule teeth of the developing young are visible on very close inspection.

Scientists thought that, in extinct reptiles, live birth was restricted to aquatic species, such as marine ichthyosaurs. These creatures would have been able to move through water with relative ease, even when heavily pregnant. The fossilized mother lizard, found in northeastern China, has been identified as a specimen of Yabeinosaurus, a large, slow-growing and relatively primitive lizard. (IANS) link.1, Link2

Caffeine Consumption' Can Drive Female Infertility!

Caffeine Consumption' Can Drive Female Infertility! :

Caffeine reduces muscle activity in the fallopian tubes that carry eggs from a woman’s ovaries to her womb, which can reduce a woman’s chance of becoming pregnant. “This finding goes a long way towards explaining why drinking caffeinated drinks can reduce a woman’s chance of becoming pregnant,” says Sean Ward, who led the study.

Ward is professor of physiology and cell biology at the University of Nevada School of Medicine who conducted these experiments on mice. Human eggs are microscopically small, but need to travel to a woman’s womb if she is going to have a successful pregnancy, according to a Nevada statement.

Although the process is essential for a successful pregnancy, scientists know little about how eggs move through the muscular Fallopian tubes, reports the British Journal of Pharmacology. It was generally assumed that tiny hair-like projections, called cilia, in the lining of the tubes, waft eggs along assisted by muscle contractions in the tube walls.

By studying tubes from mice, Ward and his team discovered that caffeine stops the actions of specialised cells in the wall of the tubes. These cells coordinate tube contractions so that when they are inhibited, eggs can’t move down the tubes. In fact, these muscle contractions play a bigger role than the beating cilia in moving the egg towards the womb.

“This provides an intriguing explanation as to why women with high caffeine consumption often take longer to conceive than women who do not consume caffeine,” said Ward. “As well as potentially helping women who are finding it difficult to get pregnant, a better understanding of the way Fallopian tubes work will help doctors treat pelvic inflammation and sexually-transmitted disease more successfully,” said Ward.(IANS) via

Discussion with adults can decrease teens’ marijuana use

Discussion with adults can decrease teens’ marijuana use : A brief, voluntary conversation with adults leads to up to a 20 percent decrease in marijuana use for teenagers who frequently use the drug, according to a new research. To many people, smoking pot is no big deal. They cite reasons such as: "it isn't dangerous or addictive" and "everybody is doing it."

Denise Walker, co-director of the University of Washington's Innovative Programs Research Group, disagrees. "It's not a risk-free drug," she said.

"Lots of people who use it do so without problems. But there are others who use it regularly - almost daily - and want to stop but aren't sure how." "Many teens also have concerns about their use, even if they're not sharing them with family or friends," she added.

The participants in the motivational interviewing group-in which the health educator and student discussed the student's marijuana use and how it might be interfering with the student's life, goals and personal values, and about social norms of how much others use the drug-started the study using marijuana 40 out of the previous 60 days. Three months after counseling they had decreased their use 20 percent, to 32 out of 60 days. After a year they still showed a 15 percent decrease, 34 days out of 60. The study was published in the journal Psychology of Addictive Behaviors. (ANI)
