From Science Daily:

Science Daily (Dec. 19, 2009) — Why does a human baby need a full year before it can start walking, while a newborn foal gets up on its legs almost directly after birth? Scientist have assumed that human motor development is unique because our brain is unusually complex and because it is particularly challenging to walk on two legs. But now a research group at Lund University in Sweden has shown that human babies in fact start walking at the same stage in brain development as most other walking mammals, from small rodents to elephants.

15 Cigarettes: All It Takes To Harm Genes

Scientists believe this new insight into the genetics of cancer will eventually lead to new drugs that target the specific changes to the gene that helps to trigger the disease. ALAMY

From The Independent:

Study reveals the genetic mutations suffered by smokers who go on to develop lung cancer.

One genetic mutation occurs on average for every 15 cigarettes that a typical lung-cancer patient smokes, according to a study that has identified for the first time all of the mutations acquired during the lifetime of a cancer patient.

Scientists have completed a full genetic analysis of the genomes of cancer patients, and hope the information will lead to a fundamental understanding of the causes of cancer – and possibly drugs and treatments – by identifying the mutations that turn a healthy cell into a cancerous tumour cell.

Marijuana, Alcohol Addiction May Share Genes

From Yahoo News/Health Day:

FRIDAY, Dec. 18 (HealthDay News) -- The genes that make people susceptible to alcoholism also make them prone to becoming addicted to marijuana, a new study suggests.

Researchers interviewed almost 6,300 men and women aged 24 to 36, including almost 2,800 sets of twins who were part of the Australian Twin Registry, about their use of alcohol and marijuana over their lifetime.

Twins are valuable to researchers in determining the role of genetics in various diseases or conditions because identical twins share 100 percent of their genes, while fraternal twins share 50 percent of their genes, the same as other siblings.

Data Deluge Will Reboot Our Brains

We are being bombarded with increasing amounts of information, although scientists say the brain itself is not under threat. (Pete Saloutos)

From Times Online:

The speed of modern life is 2.3 words per second, or about 100,000 words a day. That is the verbiage bombarding the average person in the 12 hours they are typically awake and “consuming” information, according to a new study.

Through emails, texting, internet surfing, reading and other media, our brains are being deluged with increasing quantities of information. Although we may not actively read 100,000 words a day, that is the approximate number reaching our eyes and ears. Add images, such as videos and computer games, and we are faced with the equivalent of 34 gigabytes of information each day — enough to overload the typical laptop inside a week.

Cooking Is What Made Us Human


From New Scientist:

What was the central mystery of human evolution that you were trying to solve?

I was sitting next to the fire in my living room and I started asking the question, when did our ancestors last live without fire? Out of this came a paradox: it seemed to me that no human with our body form could have lived without it.

Why can't a human exist on the same diet as a chimpanzee?

A chimpanzee's diet is like eating crab apples and rose hips. Just go into the woods and find some fruits, and see if you can come back with a full stomach. The answer is you can't. The big difficulty is that the nutrient density is not very high. This is problematic for humans because we have a very small gut, about 60 per cent of the volume it would be if we were one of the other great apes. We don't have enough intestine to keep low-quality food in our gut long enough to digest it.

Avatar's Moon Pandora Could Be Real, Planet-Hunters Say

This artist's conception shows a hypothetical gas giant planet with an Earth-like moon similar to the moon Pandora in the movie Avatar. New research shows that, if we find such an "exomoon" in the habitable zone of a nearby star, the James Webb Space Telescope will be able to study its atmosphere and detect key gases like carbon dioxide, oxygen, and water. The key is to find a planet that transits its star, and then find a moon orbiting that planet more than one stellar radius away, so that the moon can be studied independently of the planet. Moreover, an alien moon orbiting the gas giant planet of a red dwarf star may be more likely to be habitable than tidally locked Earth-sized planets or super-Earths. (Credit: David A. Aguilar, CfA)

From Science Daily:

Science Daily (Dec. 18, 2009) — In the new blockbuster Avatar, humans visit the habitable -- and inhabited -- alien moon called Pandora. Life-bearing moons like Pandora or the Star Wars forest moon of Endor are a staple of science fiction. With NASA's Kepler mission showing the potential to detect Earth-sized objects, habitable moons may soon become science fact.

If we find them nearby, a new paper by Smithsonian astronomer Lisa Kaltenegger shows that the James Webb Space Telescope (JWST) will be able to study their atmospheres and detect key gases like carbon dioxide, oxygen, and water vapor.

How High Will The Seas Go In A Warmer World?

Remi Benali / Corbis

From Time Magazine:

Even as negotiators scramble to salvage an agreement at the foundering Copenhagen climate talks, a new study in this week's issue of Nature shows that the consequences of inaction on reducing emissions could be more severe than anyone thought.

By looking back about 125,000 years, to a time when global temperatures were as high as they are expected to be by 2100, a team of scientists from Princeton and Harvard universities has calculated that the oceans were probably at least 26 ft. higher than they are now, maybe as much as 31 ft. higher. That's significantly higher than the 13-ft.-to-19-ft. range scientists have been counting on, and it is, write Peter Huybers of Harvard and Peter Clark of Oregon State University in an accompanying commentary in Nature, "a disconcerting message."

From Air And Space Smithsonian:

The blimp—that bloated, egg-shaped thing that blocks out the sun at major public events—remains one of aviation’s oddballs. Think Stay Puft Marshmallow Man in the movie Ghostbusters. And it’s a high-maintenance oddball: lots of construction and operating costs relative to the few people it carries. No speed. Huge amounts of hangar space needed to shelter it when nasty weather arrives. How does this thing get work? Other than hoisting cameras above the Super Bowl for 10-second shots during TV commercial breaks, the blimp, or zeppelin as it’s never called anymore, has been a caricature of itself for decades.

British scientists announced yesterday that they have sequenced a "cancer genome" for the first time. It means they have identified all of the many thousands of genetic mistakes that make a tumour cell different from a healthy cell taken from the same cancer patient.

Not all of these mistakes, or DNA mutations, were involved in triggering the cancer, but some of them – the "drivers" – clearly were. Scientists believe it will be possible eventually to identify these driver mutations and find the genetic faults that led to the changes in a healthy human cell that caused it to divide uncontrollably to form a cancerous tumour.

Davy Jones's Lock-Up


From The Economist:

Underwater robots can help study the world’s shipwrecks, a trove of information about the past, more easily and cheaply.

A SHIPWRECK is a catastrophe for those involved, but for historians and archaeologists of future generations it is an opportunity. Wrecks offer glimpses not only of the nautical technology of the past but also of its economy, trade, culture and, sometimes, its warfare. Until recently, though, most of the 3m ships estimated to be lying on the seabed have been out of reach. Underwater archaeology has mainly been the preserve of scuba divers. That has limited the endeavour to waters less than 50 metres deep, excluding 98% of the sea floor from inspection. Even allowing for the tendency of trading vessels to be coasters rather than ocean-going ships, that limits the number of wrecks available for discovery and examination.

Climate change is not the fault of man. It's Mother Nature's way. And sucking greenhouse gases from the atmosphere is too limited a solution. We have to be prepared for fire or ice, for fry or freeze. We have to be prepared for change.

'Jesus-Era' Burial Shroud Found

From The BBC:

A team of archaeologists and scientists says it has, for the first time, found pieces of a burial shroud from the time of Jesus in a tomb in Jerusalem.

The researchers, from Hebrew University and institutions in Canada and the US, said the shroud was very different from the controversial Turin Shroud.

Some people believe the Turin Shroud to have been Christ's burial cloth, but others believe it is a fake.

The newly found cloth has a simpler weave than Turin's, the scientists say.

From Stltoday:

When Sheila Effan found a Kindle electronic reader among her gifts last Christmas, one of her first thoughts was whether she'd miss the smell and feel of real paper. She got her answer five months later.

That's when a friend lent her a paperback. She lugged it around for a couple of days before tiring of the burden.

"I got annoyed with it. So I just downloaded it to my Kindle," Effan said. "I thought I would miss books. But I don't."

Oh, how the folks behind Amazon.com's Kindle, Sony's Reader and Barnes & Noble's Nook love the sound of that.

Climate Change Does Not Always Lead to Conflict

From Science Daily:

Science Daily (Dec. 17, 2009) — The climate change that took place in Mesopotamia around 2000 BC did not lead to war, but in fact led to the development of a new shared identity. Although increasing drought often leads to competition and conflict, there seems to be no evidence of this in northern Mesopotamia according to Dutch researcher Arne Wossink.

Wossink studied how the farmers and nomads in northern Mesopotamia -- currently the border area between Turkey, Syria and Iraq -- responded to the changes in climate that took place between 3000 and 1600 BC. He expected to find considerable evidence of competition: as food and water became scarcer the natural result could well be conflict. He discovered, however, that the farmers developed much closer bonds with the semi-nomadic cattle farmers.

Earth's Upper Atmosphere Cooling Dramatically

New research shows that the outermost layer of the atmosphere will lose 3 percent of its density over the coming decade, a sign of the far-reaching impacts of greenhouse gas emissions. As the density declines, orbiting satellites experience less drag. Credit: ©UCAR.

From Live Science:

SAN FRANCISCO — When the sun is relatively inactive — as it has been in recent years — the outermost layer of Earth's atmosphere cools dramatically, new observations find.

The results could help scientists better understand the swelling and shrinking of our planet's atmosphere, a phenomenon that affects the orbits of satellites and space junk.
