From Science In Africa:

Studies published in the journal Science reports that early modern humans living 72 000 years ago along the south coast of South Africa used fire to improve the quality and efficiency of their stone tool manufacturing. This research provides further evidence that this area may have been the origin location for the lineage that leads to all modern humans, which appeared between 100,000 and 200,000 years ago in Africa.

From Science Daily:

Science Daily (Oct. 6, 2009) — One hundred and fifty years ago, Charles Darwin's Origin of the Species revolutionised how we view the natural world. Now his voyages on HMS Beagle are influencing modern research on the evolution of our climate.

A ground-breaking partnership between JISC, the University of Sunderland, the Met Office Hadley Centre and the British Atmospheric Data Centre sees historical naval logbooks being used for the first time in research into climate change. The logbooks include famous voyages such as the Beagle, Cook’s HMS Discovery and Parry’s polar expedition in HMS Hecla.

Does Taste Decrease With Age?

From Live Science:

This Week’s Question: I have a bet with a friend that you start losing your sense of taste as you get older. She says that her taste is as strong as ever and thinks I’m wrong. Who wins the bet?

In general, sensitivity to taste gradually decreases with age. But there are some whose taste isn’t affected by getting older. Who wins the bet? I won’t touch that one.

The ability to taste food and beverages means a lot to seniors. Let’s face it; we lose a lot of the pleasures of our youth, but eating well isn’t usually one of them.

Abruptly Forgotten: Working Memory Disappears In A Blink

From Scientific American:

Certain memories die suddenly rather than fading away.

When you go from bed to bathroom on a dark night, a quick flick of the lights will leave a lingering impression on your mind’s eye. For decades evidence suggested that such visual working memories—which, even in daylight, connect the dots to create a complete scene as the eyes dart around rapidly—fade gradually over the span of several seconds. But a clever new study reported in the journal Psychological Science finds that such memories actually stay sharp until they are suddenly lost.

From The Telegraph:

Global warming could reveal lucrative reserves of untapped oil, gas and precious metals beneath the ice caps in the near future - but at what environmental cost?

For all the talk among world leaders of the perils of climate change, many are scenting an opportunity. As the Arctic ice retreats, surrounding nations are looking to plunder those natural resources under the surface, estimated by the US Geological Survey to constitute as much as 13 per cent of the world’s undiscovered oil and 30 per cent of its undiscovered natural gas – as well as precious metals including iron ore, gold, zinc and nickel.

From Times Online:

Nasa will not be able to meet its target of sending humans back to the Moon by 2020, or even dream of landing on Mars, because it is suffering from chronic underfunding, a presidential review panel has warned.

The US space agency needs at least another $50 billion (£30 billion) over the next decade if it is to come close to delivering on its vision for retiring the space shuttle, completing construction of the International Space Station and launching ambitious new voyages of discovery.

The bleak assessment comes from a ten-member committee established by President Obama to review America’s manned spaceflight programme. Made up of aerospace experts and former astronauts, it is not due to make its final report until the end of this month.

Why Women Have Sex

RCWW Inc. / Corbis

From Time Magazine:

While figuring out what women want has stumped men for centuries, understanding how they think about sex may have just gotten easier. Cindy Meston and David Buss, psychologists at the University of Texas, interviewed over 1,000 women around the world for their book Why Women Have Sex and managed to come up with 237 reasons, ranging from the predictable — commitment — to the puzzling — curing a headache. Spoiler alert: love may be further down on the list than one might think. TIME spoke to Buss about the myriad mind games, turn-ons and turn-offs involved in female sexuality, and what a guy can do to stand a chance.

Acidic Clouds Nourish World's Oceans

Water droplets in clouds generally form around dust and other particles. When clouds evaporate, as they often do naturally, the surface of the particle can become very acidic. This is especially true where the air is polluted. Paradoxically, scientists suggest that large scale industry in countries like China could be combating global warming to some extent by creating more bioavailable iron in the oceans, and therefore increasing carbon dioxide removal from the atmosphere. (Credit: Copyright Michele Hogan)

From Science Daily:

Science Daily (Oct. 6, 2009) — Scientists at the University of Leeds have proved that acid in the atmosphere breaks down large particles of iron found in dust into small and extremely soluble iron nanoparticles, which are more readily used by plankton.

This is an important finding because lack of iron can be a limiting factor for plankton growth in the ocean - especially in the southern oceans and parts of the eastern Pacific. Addition of such iron nanoparticles would trigger increased absorption of carbon dioxide from the atmosphere.

Ancient Rome's Real Population Revealed

From Live Science:

The first century B.C. was one of the most culturally rich in the history of the Roman Empire — the age of Cicero, Caesar and Virgil. But as much as historians know about the great figures of this period of Ancient Rome, they know very little about some basic facts, such as the population size of the late Roman Empire.

Now, a group of historians has used caches of buried coins to provide an answer to this question.

During the Republican period of Rome (about the fifth to the first centuries B.C), adult male citizens of Rome could be taxed and conscribed into the army and were also given the right to vote. To keep track of this section of the population (and their taxable assets), the Roman state conducted periodic censuses.

My Book Is Mine, Not Google's -- A Commentary

Who's book is it anyway? (Image: Andrzej Krauze)

From New Scientist:

NEXT week details of a plan that could shape the future of books and publishing in the digital age will be spelled out in a New York courtroom. The plan is complex but, in a nutshell, search engine giant Google intends to scan and make available perhaps a million or more books that are out of print but still in copyright.

Google has the support of the Authors Guild and the Association of American Publishers, but it faces formidable opposition. Some 400 legal objections have been filed, and the US Department of Justice has serious concerns. The dispute was due to be resolved in court next week, but at the last minute Google and its partners asked for the case to be adjourned so they could make revisions. A hearing will still take place, but only to inform the parties concerned how Google intends to proceed.

Light Pollution: Night Skies, Dark No More

(Click Image to Enlarge)

From U.S. News And Report:

The ecological risks and health effects of a bright night are becoming more apparent.

The night is not what it was. Once, the Earth was cast perpetually half in shadow. Man and beast slept beneath inky skies, dotted with glittering stars. Then came fire, the candle, and the light bulb, gradually drawing back the curtain of darkness and giving us unprecedented control over our lives.

But a brighter world, it is becoming increasingly clear, has its drawbacks. A study released last month finding that breast cancer is nearly twice as common in brightly lit communities as in dark ones only added to a growing body of evidence that artificial light threatens not just stargazing but also public health, wildlife, and possibly even safety.

Why Nondrinkers May Be More Depressed

Ruediger Knobloch / A.B. / Corbis

From Time Magazine:

Alcohol has a peculiar relationship to happiness. We drink to celebrate, but because alcohol works as a depressant, it ends up deadening feelings. Not surprisingly, there's an observable correlation between alcoholism and depression, and even though it's not always clear which leads to which, everyone knows you can't drink like a Sterling Cooper employee for too long before becoming a perpetual sad sack.

But if alcohol can lead to depression, does that mean abstaining from alcohol will make you happier? A new study suggests that the opposite actually tends to be true. In fact, those who never drink are at significantly higher risk for not only depression but also anxiety disorders, compared with those who consume alcohol regularly.

New Vaccine May Immunize Addicts from Cocaine's Pleasurable Effects

HIGH HOPES: Vaccines to decrease cocaine use have been in the works for years, but this new trial has had some encouraging results. ISTOCKPHOTO/MILOSJOKIC

From Scientific American:

Clinical trial data suggest that although pharmacotherapy for cocaine may be on the horizon, challenges remain.

Unlike opiates such as heroin or prescription painkillers, there is no medication specifically approved to help curb cocaine consumption. Now, an experimental vaccine offers hope for a new approach, researchers say, that spurs on antibodies, which bind with cocaine molecules and apparently helps some addicts stop feeling the pleasurable effects of the drug—thus deconditioning them out of their dependency.
