From Yahoo News/AP:

WASHINGTON – More than 2 trillion tons of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming.

More than half of the loss of landlocked ice in the past five years has occurred in Greenland, based on measurements of ice weight by NASA's GRACE satellite, said NASA geophysicist Scott Luthcke. The water melting from Greenland in the past five years would fill up about 11 Chesapeake Bays, he said, and the Greenland melt seems to be accelerating.

NASA scientists planned to present their findings Thursday at the American Geophysical Union conference in San Francisco. Luthcke said Greenland figures for the summer of 2008 aren't complete yet, but this year's ice loss, while still significant, won't be as severe as 2007.

Can Nuclear Power Compete?

From Science America:

Newly approved reactor designs could reduce global warming and fossil-fuel dependence, but utilities are grappling with whether better nukes make market sense

On an August afternoon in Washington, D.C., typically miserable for its heat, humidity and stillness, reporters gathered at a downtown hotel not known for its air-conditioning. Stuffed inside a windowless conference room that was being heated still further by the television people’s lights, we waited for Michael J. Wallace, who had been trying, in fits and starts, to unveil nuclear power’s second act.

On arrival, Wallace, a meticulous manager not known for ad-libbing, looked out over the sweating reporters and smiled. “It’s days like today that highlight the real need for new, emissions-free, baseload power,” he said. Unless we get started soon, he added, rolling blackouts could become the norm.

'Death Map' Shows Heat A Big Hazard To Americans

From Reuters:

WASHINGTON, Dec 16 (Reuters) - Heat is more likely to kill an American than an earthquake, and thunderstorms kill more people than hurricanes do, according to a U.S. "death map" published on Tuesday.

Researchers who compiled the county-by-county look at what natural disasters kill Americans said they hope their study will help emergency preparedness officials plan better.

Heat and drought caused 19.6 percent of total deaths from natural hazards, with summer thunderstorms causing 18.8 percent and winter weather causing 18.1 percent, the team at the University of South Carolina found.

Earthquakes, wildfires and hurricanes combined were responsible for fewer than 5 percent of all hazard deaths.

Writing in BioMed Central's International Journal of Health Geographics, they said they hoped to dispel some myths about what the biggest threats to life and limb are.

"According to our results, the answer is heat," Susan Cutter and Kevin Borden of the University of South Carolina wrote in their report, which gathered data from 1970 to 2004.

From NPR:

Plummeting gasoline and diesel prices have given consumers relief at the pump. But oil pessimists believe the current slump in demand will pass. And when it does, the world will be in the same fix it was before the global recession. The era of easy oil is behind us. According to those who believe in what's called "peak oil theory," world oil production has already peaked, or flattened, and in the foreseeable future, the declining resource will inevitably change the way we live.

Google Says It Still Stands By Net Neutrality

From Yahoo Finance/AP:

Google denies Wall Street Journal claim that it's giving up on `Net neutrality'

NEW YORK (AP) -- Google Inc. denied that it had reversed its stance on the issue of "Net neutrality" and dismissed a story in Monday's edition of The Wall Street Journal on the subject as "confused."

Citing undisclosed sources, the newspaper reported that Google had been in talks with major cable and phone companies about getting preferential treatment for traffic to and from its sites.

That would conflict with the principle of Net neutrality, under which carriers traditionally give the same treatment to traffic from different sites. The Federal Communications Commission has voiced support for the principle, and sanctioned Comcast Corp. this year for slowing some types of file-sharing traffic. Google has been a vocal supporter of Net neutrality.

Google Wants Its Own Fast Track On The Web

From The Wall Street Journal:

The celebrated openness of the Internet -- network providers are not supposed to give preferential treatment to any traffic -- is quietly losing powerful defenders.

Google Inc. has approached major cable and phone companies that carry Internet traffic with a proposal to create a fast lane for its own content, according to documents reviewed by The Wall Street Journal. Google has traditionally been one of the loudest advocates of equal network access for all content providers.

At risk is a principle known as network neutrality: Cable and phone companies that operate the data pipelines are supposed to treat all traffic the same -- nobody is supposed to jump the line.

But phone and cable companies argue that Internet content providers should share in their network costs, particularly with Internet traffic growing by more than 50% annually, according to estimates. Carriers say that to keep up with surging traffic, driven mainly by the proliferation of online video, they need to boost revenue to upgrade their networks. Charging companies for fast lanes is one option.

Doctor's Advice: Leave the Toilet Seat Up

From Live Science:

One of the longest-running spousal debates may now be settled in favor of men and for the sake of little boys.

Leave the toilet seat up, some British doctors now say. The reason: a rising trend for heavy wooden and ornamental toilet seats to fall down onto the penises of unsuspecting (and just potty-trained) toddlers.

Dr. Joe Philip and his colleagues of Leighton Hospital, Crewe, in England detail such penis-crush injuries in the December issue of the journal BJU International. The team reports on four boys between the ages of 2 and 4 who were admitted to hospitals with injuries serious enough to require an overnight stay.

Supermassive Black Hole Dissected With Natural Magnifying Glasses: 1,000 Times Clearer Than Best Telescopes Can Do

Close-up of the Einstein Cross, as observed with the SINFONI instrument on ESO's Very Large Telescope. SINFONI makes use of the adaptive optics technique and so, allows astronomers to overcome the blurring effect of the atmosphere, thereby providing very sharp images. The central blob is the nucleus of the lensing galaxy, surrounded by the four mirage images of the distant quasar. (Credit: ESO/F. Courbin et al)

From Science Daily:

ScienceDaily (Dec. 13, 2008) — Combining a double natural "magnifying glass" with the power of ESO's Very Large Telescope, astronomers have scrutinised the inner parts of the disc around a supermassive black hole 10 billion light-years away. They were able to study the disc with a level of detail a thousand times better than that of the best telescopes in the world, providing the first observational confirmation of the prevalent theoretical models of such discs.

The team of astronomers from Europe and the US studied the "Einstein Cross", a famous cosmic mirage. This cross-shaped configuration consists of four images of a single very distant source. The multiple images are a result of gravitational lensing by a foreground galaxy, an effect that was predicted by Albert Einstein as a consequence of his theory of general relativity. The light source in the Einstein Cross is a quasar approximately ten billion light-years away, whereas the foreground lensing galaxy is ten times closer. The light from the quasar is bent in its path and magnified by the gravitational field of the lensing galaxy.

Year's Biggest Full Moon Friday Night

From Space.com

The full moon Friday night will be the biggest one of the year as Earth's natural satellite reaches its closest point to our planet.

Earth, the moon and the sun are all bound together by gravity, which keeps us going around the sun and keeps the moon going around us as it goes through phases. The moon makes a trip around Earth every 29.5 days. But the orbit is not a perfect circle.

The moon's average distance from us is about 238,855 miles (384,400 km). Friday night it will be just 221,560 miles (356,567 km) away. It will be 14 percent bigger in our sky and 30 percent brighter than some other full moons during the year, according to NASA.

Tides will be higher Friday night, too. Earth's oceans are pulled by the gravity of the moon and the sun. So when the moon is closer, tides are pulled higher. Scientists call these perigean tides, because the moon's closest point to Earth is called perigee. The farthest point on the lunar orbit is called apogee.

At this time of the year, the pressure to shop, buy and wrap is overwhelming. And so we drag ourselves to the mall, a hopefully one-stop shopping place where any number of stores can accommodate any holiday shopping list.

Look Up Tonight For A Spectacular Treat In The Sky

From Times Online:

Biggest full moon for years enhanced by shooting stars

If the full moon tonight looks unusually large, it is not your imagination – it is the biggest and brightest full moon to be seen for 15 years.

Each month the Moon makes a full orbit around the Earth in a slightly oval-shaped path, and tonight it will swing by the Earth at its closest distance, or perigee. It will pass by 356,613km (221,595 miles) away, which is about 28,000km closer than average.

The unusual feature of tonight is that the perigee also coincides with a full moon, which will make it appear 14 per cent bigger and some 30 per cent brighter than most full moons this year – so long as the clouds hold off from blocking the view.

Ancient Indian Ocean Coral Points To Another Disastrous Tsunami

From Times Online:

The eastern Indian Ocean could be due for another earthquake rivalling the one that caused the deadly tsunami in December 2004, according to research on ancient corals in the area.

It has long been said that earthquakes occur in cycles, yet until now evidence has been hard to come by. Now a pioneering study of the corals off the west coast of Sumatra has revealed that the region's earthquakes during the past 700 years occurred in series of shocks that spanned decades.

Corals lay down growth rings every year, just like trees, and these record environmental changes including upheavals of the seabed. They show that the region's earthquakes usually come in a sequence.

(PhysOrg.com) -- NASA's Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. This is an important step along the trail of finding the chemical biotracers of extraterrestrial life as we know it.

The Jupiter-sized planet, called HD 189733b, is too hot for life. But the Hubble observations are a proof-of-concept demonstration that the basic chemistry for life can be measured on planets orbiting other stars. Organic compounds can also be a by-product of life processes, and their detection on an Earth-like planet may someday provide the first evidence of life beyond Earth.

The Energy Debates: Ocean Thermal Energy Conversion

From Live Science:

The Facts

Most of the planet is covered by the oceans, and they absorb a staggering amount of energy from the sun each day. Ocean thermal energy conversion, or OTEC, taps into this energy to produce electricity.

Ocean thermal energy conversion relies on the fact that water near the surface is heated by sunlight while seawater deep in the dark is much colder. OTEC plants use warm surface water to heat ammonia or some other fluid that boils at a low temperature. The resulting gas is used to drive turbines that produce electricity. The gas is then cooled by cold water pumped up from the ocean depths and the resulting fluid is recycled to help generate power.

It didn’t start that way: His land was once a low hill in a rugged hardwood forest – cherry, oak, hickory – skipping from ridge to ridge across one of the poorest, most rural areas of the Lower 48.

Then came the mining companies with their dynamite and trucks. They clear-cut the forest, blew the tops off the ridges and scraped the rocks into the hollows, pushing hundreds of feet of mountains into the valleys below.

They came for the coal – energy that provides half of the nation’s electricity and has been touted as a major plank in the United State’s bid for energy independence. They left, in Gibson’s view, a swale of extirpation and death.

1/5 Of Coral Reefs Lost Due To Acid-Filled Oceans

From National Geographic:

The world has lost nearly one-fifth of its coral reefs, and much of the rest could be destroyed by increasingly acidic seas if climate change continues unchecked, a conservation group warned Wednesday.

Rising temperatures from greenhouses gases are the latest and most serious threats to coral, which are already being damaged by destructive fishing methods and pollution, according to the International Union for Conservation of Nature (IUCN).

About 19 percent of coral reefs have disappeared during the last 20 years, said IUCN's director general, Julia Marton-Lefèvre.

"If current trends in carbon dioxide emission continue, many of the remaining reefs will be lost in the next 20 to 40 years," Marton-Lefèvre said at Wednesday's U.N. talks, which are focused on creating a new climate change treaty.

Hubble Finds Carbon Dioxide on Extrasolar Planet

From Wired Science:

The Hubble Space Telescope has detected carbon dioxide in the atmosphere of a planet outside of the solar system, a significant step in the search for extraterrestrial life.

Though the planet is more similar to Jupiter than Earth and is too hot to harbor life, the ability to identify organic compounds on other planets is key to being able to find other habitable worlds, and potentially life.

"The carbon dioxide is kind of the main focus of the excitement, because that is a molecule that under the right circumstances could have a connection to biological activity as it does on Earth," astronomer Mark Swain of NASA's Jet Propulsion Laboratory said in a press release. "The very fact that we're able to detect it, and estimate its abundance, is significant for the long-term effort of characterizing planets both to find out what they're made of and to find out if they could be a possible host for life."

Step aside, quacks. The search for longer life is a real science now.

By the time it reaches the age of 18 days, the average roundworm is old, flabby, sluggish and wrinkled. By 20 days, the creature will likely be dead—unless, that is, it's one of Cynthia Kenyon's worms. Kenyon, director of the Hillblom Center for the Biology of Aging at the University of California, San Francisco, has tinkered with two genes that turn simple worms into mini-Methuselahs, with life spans of up to 144 days. "You can beat them up in ways that would kill a normal worm—exposing them to high heat, radiation and infectious microbes—and still they don't die," she says. "Instead, they're moving and looking like young worms. It's like a miracle—except it's science."

Virus could explain one symptom of colony collapse

There’s bad news for diehards still arguing that honeybees are getting abducted by aliens.

Beehives across North America continue to lose their workers for reasons not yet understood, a phenomenon called colony collapse disorder. But new tests suggest how a virus nicknamed IAPV might be to blame for one of the more puzzling aspects of the disorder—the impression that substantial numbers of bees vanish into thin air.

In tests on hives in a greenhouse, bees infected with IAPV (short for Israeli acute paralytic virus) rarely died in the hive. Sick bees expired throughout the greenhouse, including near the greenhouse wall, Diana Cox-Foster of Pennsylvania State University in University Park reported November 18 in Reno, Nev., at the annual meeting of the Entomological Society of America.

The two tests took place in Kenya and Tanzania, and included 340 and 894 children, respectively. After vaccination, children were visited in their homes to follow up on their health and most importantly, their contraction (or not) of malaria.

Here are some highlights from the results:

Making Vinegar At Home

Maple Vinegar: Aki Kamozawa and H. Alexander Talbot

From Popsci:

Turn sour old wine into a beautiful holiday gift -- thanks to science.

Vinegar is one of those ingredients that people don't think of as often as they should. It is mostly just seen in salad dressings and pickles, which is a shame, because there is a whole world of flavor there just waiting to be tapped into. There are often times, especially during the holidays, when there is leftover wine after a festive dinner. Many of us will cork the bottle, with or without various safeguards to preserve the contents, and set it aside for the next day. Occasionally the bottles are forgotten, and when you finally open them again you find that the wine has evolved into something quite a bit different from what you were expecting. In these moments the change is often viewed with disappointment, as a delicate beverage has transformed into something sharper and edgier. Frankly, though, a smart cook will see the change as an opportunity. Good wine makes good vinegar and good vinegar is a stellar cooking ingredient.

Why Do Men Buy Sex?

From Scientific Magazine:

* In the U.S., police officers detained about 78,000 people in 2007 for prostitution-related crimes, according to the Federal Bureau of Investigation. Only about 10 percent of these arrests are of the sex patrons, who almost exclusively are men.
* A considerable proportion of men worldwide buy sex from female prostitutes, with most estimates of lifetime prevalence ranging from 7 to 39 percent, depending on the country and study. Many experts argue that it is a male appetite—and not the choices of prostitutes—that fundamentally drives the sex trade.
* Men’s motives for buying sex are hotly contested among researchers. Some believe the practice serves as a salve for common psychological afflictions, such as an unfulfilled craving for sex or romance. Others, meanwhile, paint a dimmer portrait of johns, believing they are driven by chauvinistic motives, such as a desire to dominate and control women.

Large Hadron Collider Repairs To Cost £14million

Extensive work will be needed to fix the Large Hadron Collider after a problem thought to be related to a faulty electrical connection Photo: GETTY IMAGES

From The Telegraph:

Repairs to the Large Hadron Collider, dubbed the biggest experiment in history, will cost almost £14m and take until at least next summer to be completed.

A faulty electrical connection between magnets was likely to blame for a large helium leak which caused the £4.4m LHC to be shut down in September.

At first the European Organization for Nuclear Research (CERN) thought it would only be out of action until last month but the damage was worse than expected.

Now it is hoped repairs will be completed by May or early June with the machine restarted at the end of June or later.

James Gillies, a CERN spokesman, said: "If we can do it sooner, all well and good. But I think we can do it realistically (in) early summer.

Early Snowfalls In Europe Hit Historic Levels

From Watts Up With That?:

Early snowfalls in Europe hit Historic Levels
Posted Wednesday 3rd December 2008, 2:15 pm by Dunx

* 20 year record snowfall in Dolomites enough to last all season
* Some Swiss train services cancelled due to excess snow
* Still more heavy snow in the Pyrenees
* More snow for Scotland

www.Skiinfo.com is following still more heavy snowfalls across Europe over the past 48 hours, with much more snow in other parts of Europe and many areas of North America too.

The snowfall has been so great that it has closed roads, brought down power lines and even led to the cancellation of some Swiss rail services this week.

Is Einstein The Last Great Genius?

From Live Science:

Major breakthroughs in science have historically been the province of individuals, not institutes. Galileo and Copernicus, Edison and Einstein, toiling away in lonely labs or pondering the cosmos in private studies.

But in recent decades — especially since the Soviet success in launching the Sputnik satellite in 1957 — the trend has been to create massive institutions that foster more collaboration and garner big chunks of funding.

And it is harder now to achieve scientific greatness. A study of Nobel Prize winners in 2005 found that the accumulation of knowledge over time has forced great minds to toil longer before they can make breakthroughs. The age at which thinkers produce significant innovations increased about six years during the 20th century.

Dogs Can Feel Envy, Study Suggests

Dogs can feel envy, a December 2008 study suggests. In experiments with 43 dogs, an Austrian research team showed that dogs reacted to inequity. One dog watched another dog receive a reward for a trick. When the watcher dog performed the same trick and was not rewarded, that dog refused to do the trick again.

From National Geographic:

The first scientific study to find envy in non-primates affirms what many already know: dogs can get jealous.

"Everybody who has a dog at home probably [suspects] that dogs can be very jealous of other dogs and also of people," said lead author Friederike Range of the University of Vienna, Austria.

In experiments with 43 dogs, Range's team showed that the canines reacted to inequity.

The team had one dog watch another dog receive a reward for doing a trick. When the watching dog performed the same trick and was not rewarded, that dog refused to do the trick again, Range said.

Will Solar Power Ever Be As Cheap As Coal?

From The Christian Science Monitor:

Some predict that within five years, it could rival fossil-fuel energy.

Lexington, Mass.

“Solar power is the energy of the future – and always will be.”

That tired joke, which has dogged solar-generated electricity for decades due to its high cost, could be retired far sooner than many think.

While solar contributes less than 1 percent of the energy generated in the United States today, its costs are turning sharply downward.

Whether using mirrors that focus desert sunlight to harvest heat and spin turbines or rooftop photovoltaic panels that turn sunshine directly into current, solar is on track to deliver electricity to residential users at a cost on par with natural gas and perhaps even coal within the next four to seven years, industry experts say.

Carbon Dioxide Helped Ancient Earth Escape Deathly Deep Freeze

Researchers speculate that during the Cryogenian Period, about 840 to 635 million years ago, advancing ice was stalled by the interaction of the physical climate system and the carbon cycle of the ocean, with carbon dioxide playing a key role in insulating the planet. (Credit: iStockphoto)

From Science Daily:

ScienceDaily (Dec. 8, 2008) — The planet’s present day greenhouse scourge, carbon dioxide, may have played a vital role in helping ancient Earth to escape from complete glaciation, say scientists in a paper published online today.

In their review for Nature Geoscience, UK scientists claim that the Earth never froze over completely during the Cryogenian Period, about 840 to 635 million years ago.

This is contrary to the Snowball Earth hypothesis, which envisages a fully frozen Earth that was locked in ice for many millions of years as a result of a runaway chain reaction that caused the planet to cool.

My Comment: I live half of the time up north in the Laurentians of Quebec. It is -22C. outside right now. Hmmmm .... more carbon dioxide please.

The Energy Debates: Solar Farms

From Ontario Solar Farms

From Live Science:

The Facts

The amount of energy from the sun that falls on Earth is staggering. Averaged over the entire surface of the planet, roughly each square yard collects nearly as much energy each year as you’d get from burning a barrel of oil. Solar farms seek to harness this energy for megawatts of power.

There are two ways solar power is used to generate electricity. Solar thermal plants — also known as concentrating solar power systems — focus sunlight with mirrors, heating water and producing steam that drives electric turbines, while photovoltaic cells directly convert sunlight to electricity.
