Ocean currents can power the world, say scientists

A revolutionary device that can harness energy from slow-moving rivers and ocean currents could provide enough power for the entire world, scientists claim.

The technology can generate electricity in water flowing at a rate of less than one knot – about one mile an hour – meaning it could operate on most waterways and sea beds around the globe.

Water vapour discovered on Saturn’s moon

Huge plumes of water vapour and ice particles are bursting out from Saturn’s moon Enceladus at supersonic speeds in a way that strongly suggests they come from liquid water down below the icy surface, scientists have said.

The research, published in the journal Nature, offers new evidence that the moon may harbor an underground ocean of water, meaning conditions might exist that could support life, even if only microbial organisms.

‘We think liquid water is necessary for life and there is more evidence that there is liquid water there,’ said lead researcher Candice Hansen of NASA’s Jet Propulsion Laboratory in Pasadena, California.

‘You also need energy, you need nutrients, you need organics. It looks like the pieces are there. Whether or not there’s actually life, of course, we can’t say.’

Scientists are aware of only three places where liquid water exists near the surface of a planet or other body – Earth, Jupiter’s moon Europa and now Enceladus.

In July Nasa’s Phoenix Mars Lander confirmed the presence of ice on Mars.

‘Heavy water’ could help us live longer

Drinking “heavy water” enriched with a rare form of hydrogen could prolong our lives by up to ten years, it has been claimed.

Mikhail Shchepinov, a former Oxford University scientist, says that the modified drink protects against dangerous chemicals known as free radicals that are known to contribute to conditions such as cancer, Alzheimer’s and Parkinson’s.

He also claims that foods such as steak and eggs could be enriched with the special hydrogen isotope, known as deuterium, raising the possibility of people being able to “eat themselves healthy”.

His research has shown that worms live 10 per cent longer and fruitflies up to 30 per cent longer when fed on heavy water, which is slightly sweeter than normal water.

Stubborn glaciers fail to retreat, awkward polar bears continue to multiply

Second only to the melting of the Arctic ice and those “drowning” polar bears, there is no scare with which the global warmists, led by Al Gore, more like to chill our blood than the fast-vanishing glaciers of the Himalayas, which help to provide water for a sixth of mankind.

Oceans Passing Critical CO2 Threshold

UXBRIDGE, Canada – An apparent rapid upswing in ocean acidity in recent years is wiping out coastal species like mussels, a new study has found.

“We’re seeing dramatic changes,” said Timothy Wootton of the Department of Ecology and Evolution at the University of Chicago, lead author of the study published Monday in the Proceedings of the National Academy of Sciences. The study shows increases in ocean acidity that are more than 10 times faster than any prediction.

“It appears that we’ve crossed a threshold where the ocean can no longer buffer the effects of CO2 in the atmosphere,” Wootton told IPS.

Mass testing plan to tackle Aids

    A radical new strategy to stop the Aids epidemic in its tracks was proposed yesterday by World Health Organisation scientists but ran into immediate controversy over its implications for human rights.

    The plan involves testing everybody for HIV every year in hard-hit areas like sub-Saharan Africa and immediately putting those who are positive on Aids drugs. It could slash dramatically the number of new infections, because Aids drugs lower the levels of virus in the body, making HIV transmission through unprotected sex much less likely.

    But the strategy, expounded in a paper published online today by the Lancet medical journal, raises major issues both over implementation and over ethics.

    Currently people who are HIV positive are not put on treatment until they need it, because of the toxicity and side-effects of antiretroviral drugs. It raises the prospect of subjecting people to potential medical harm for the public good, rather than their individual benefit. “We wouldn’t do that in the UK,” said John Howson of the International HIV/Aids Alliance. “These are huge issues.”

    Pine Bark Cuts Jet Lag in Half

    (NaturalNews) If you’ve ever taken a super long flight that lasts seven to nine hours and crossed a time zone or two, you probably know that jet lag can make you feel just plain awful — and it can keep you from enjoying your trip for at least a day or two. That can be especially aggravating when you travel over the holidays. But now comes news that a natural plant substance, an extract from the French maritime pine tree, can cut jet lag symptoms by about fifty percent.

    The new research, conducted at the G. D’Annunzio University in Pescara, Italy, and just published in the journal Minerva Cardioangiologica, reveals pine bark extract, or pycnogenol, reduced symptoms of jet lag including feeling exhausted, headaches, insomnia and brain edema (swelling). It was effective in both healthy individuals and those with high blood pressure. In addition,airline passengers experienced far less lower leg edema, a common condition associated with long flights, when they took pine bark extract.

    Plants from the Mint Family Found Highly Effective Against HIV and Herpes

    (NaturalNews) Herbs from the Lamiaceae family, also known as the mint family have been shown to drastically reduce the infectivity of HIV-1 virions, single infective viral particles. A research team from the University of Heidelberg has found that extracts of lemon balm, sage and peppermint work rapidly to produce their effects in amounts that display no toxicity. The extracts were seen to enhance the density of the virions prior to their surface engagement. They also displayed a strong activity against herpes simplex virus type 2.

    The researchers examined water extracts from the leaves of lemon balm, sage and peppermint for their potency to inhibit infection by HIV-1. They found that the extracts exhibited a high and concentration-dependent activity against the infection of HIV-1 in T-cell lines, primary macrophages, and in ex vivo tonsil histocultures. This effect was produced at extract concentrations as low as 0.004% without affect to cell viability.

    Austrian Government Study Confirms Genetically Modified (GM) Crops Threaten Human Fertility and Health Safety

    Advocates Call for Immediate Ban of All GM Foods and GM Crops

    (Los Angeles, CA.) – A long-term feeding study commissioned by the Austrian Agency for Health and Food Safety, managed by the Austrian Federal Ministry of Health, Family and Youth, and carried out by Veterinary University Vienna, confirms genetically modified (GM) corn seriously affects reproductive health in mice. Non-GMO advocates, who have warned about this infertility link along with other health risks, now seek an immediate ban of all GM foods and GM crops to protect the health of humankind and the fertility of women around the world.

    Feeding mice with genetically modified corn developed by the US-based Monsanto Corporation led to lower fertility and body weight, according to the study conducted by the University of Veterinary Medicine in Vienna. Lead author of the study Professor Zentek said, there was a direct link between the decrease in fertility and the GM diet, and that mice fed with non-GE corn reproduced more efficiently.

    In the study, Austrian scientists performed several long-term feeding trials over 20 weeks with laboratory mice fed a diet containing 33% of a GM variety (NK 603 x MON 810), or a closely related non-GE variety used in many countries. Statistically significant litter size and pup weight decreases were found in the third and fourth litters in the GM-fed mice, compared to the control group.

    The corn is genetically modified with genes that produce a pesticidal toxin, as well as genes that allow it to survive applications of Monsanto’s herbicide Roundup.
