Computer Pop-Ups Waste Time Even After They Have Disappeared

Computer annoyance: Pop-ups waste more time than they take to close, a study has found

From The Daily Mail:

The annoyance of computer screen pop-ups lasts long after they have disappeared or been closed, research has found.

Although they might stay on the screen for just a few seconds, pop-ups make us lose more time trying to find our place and resume the task that was interrupted, a Cardiff University study concluded.

The research, led by Dr Helen Hodgetts and Professor Dylan Jones, examined the cost of on-screen interruptions in terms of the time taken to complete a simple seven-step computer task.

From The BBC:

Archaeologists have found evidence of mass cannibalism at a 7,000-year-old human burial site in south-west Germany, the journal Antiquity reports.

The authors say their findings provide rare evidence of cannibalism in Europe's early Neolithic period.

Up to 500 human remains unearthed near the village of Herxheim may have been cannibalised.

The "intentionally mutilated" remains included children and even unborn babies, the researchers say.

The German site was first excavated in 1996 and then explored again between 2005 and 2008.

From Cosmos:

SYDNEY: The extinction of mammoths in North America at the end of the last ice age was not caused by a change in the ecosystem: it's what triggered the changes, a new study suggests.

The study also elucidates a possible cause for the demise of mammoths and mastodons 15,000 years ago, and researchers say that the expanded incidence of fire in the landscape - suspected of being caused by human arrival - only appeared after the extinction.

Large Moon Of Uranus May Explain Odd Tilt

A massive moon that orbited Uranus in the past may explain the planet's extreme tilt (Image: NASA/ESA/M. Showalter/SETI Institute)

From New Scientist:

Please try to resist the childish jokes, but the fact is that the odd tilt of Uranus may be the result of a particularly large moon.

Uranus spins on an axis almost parallel with the plane of the solar system, rather than perpendicular to it – though why it does this nobody knows. One theory is that the tilt is the result of a collision with an Earth-sized object, but this "hasn't succeeded in explaining much of anything", says Ignacio Mosqueira of the SETI Institute in Mountain View, California. Why, for example, are the orbits of Uranus's 27 known moons not also tilted?

From The Telegraph:

The Earth may be 50 per cent more sensitive to the warming effect of carbon dioxide greenhouse gas than has previously been thought, scientists claim.

A new study suggests bigger cuts in carbon dioxide (CO2) emissions may be needed to prevent drastic long term climate change.

The evidence was obtained by scientists looking back three million years to the Pliocene epoch, when global temperatures were 5.4F (3C) to 9F (5C) higher than they are today.

They found that levels of CO2 in the atmosphere at the time should not have produced such a warm world.

Nanowires Key To Future Transistors, Electronics

Researchers are closer to using tiny devices called semiconducting nanowires to create a new generation of ultrasmall transistors and more powerful computer chips. The researchers have grown the nanowires with sharply defined layers of silicon and germanium, offering better transistor performance. As depicted in this illustration, tiny particles of a gold-aluminum alloy were alternately heated and cooled inside a vacuum chamber, and then silicon and germanium gases were alternately introduced. As the gold-aluminum bead absorbed the gases, it became "supersaturated" with silicon and germanium, causing them to precipitate and form wires.

Having a tough time recalling a phone number someone spoke a few minutes ago or forgetting items from a mental grocery list is not a sign of mental decline; in fact, it's natural.

Countless psychological experiments have shown that, on average, the longest sequence a normal person can recall on the fly contains about seven items. This limit, which psychologists dubbed the "magical number seven" when they discovered it in the 1950s, is the typical capacity of what's called the brain's working memory.

From Science Daily:

Science Daily (Dec. 6, 2009) — Getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories, new research funded by the Wellcome Trust and Research into Ageing suggests.

The research may help explain why 'dietary restriction' (also known as calorie restriction) -- reducing food intake whilst maintaining sufficient quantities of vitamins, minerals and other important nutrients -- appears to have health benefits. In many organisms, such as the fruit fly (drosophila), mice, rats and the Rhesus monkey, these benefits include living longer. Evidence suggests that dietary restriction can have health benefits for humans, too, though it is unclear whether it can increase longevity.

Is nuclear fusion the ultimate energy source, or the ultimate pipe dream? Millions upon millions of dollars are being spent to find out which answer is the right one. For some technologies, the answer could come sooner than later. For others, it may be later rather than sooner.

The easiest way to access fusion power is to go outside on a sunny day: Nuclear fusion is the reaction that powers the sun, by crushing hydrogen atoms into helium atoms and converting the small blips of extra mass into energy. Hydrogen bombs, tested by the world's armies but never used on the battlefield, do the same thing.

Copying Birds May Save Aircraft Fuel

Photo: Corbis

From The Economist:

BOTH Boeing and Airbus have trumpeted the efficiency of their newest aircraft, the 787 and A350 respectively. Their clever designs and lightweight composites certainly make a difference. But a group of researchers at Stanford University, led by Ilan Kroo, has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use, and it would not require them to buy new aircraft.

The answer, says Dr Kroo, lies with birds. Since 1914, and a seminal paper by a German researcher called Carl Wieselsberger, scientists have known that birds flying in formation—a V-shape, echelon or otherwise—expend less energy. The air flowing over a bird’s wings curls upwards behind the wingtips, a phenomenon known as upwash. Other birds flying in the upwash experience reduced drag, and spend less energy propelling themselves. Peter Lissaman, an aeronautics expert who was formerly at Caltech and the University of Southern California, has suggested that a formation of 25 birds might enjoy a range increase of 71%.

From Science Daily:

Science Daily (Dec. 3, 2009) — Washington, D.C.—Hawaii may be paradise for vacationers, but for geologists it has long been a puzzle. Plate tectonic theory readily explains the existence of volcanoes at boundaries where plates split apart or collide, but mid-plate volcanoes such as those that built the Hawaiian island chain have been harder to fit into the theory. A classic explanation, proposed nearly 40 years ago, has been that magma is supplied to the volcanoes from upwellings of hot rock, called mantle "plumes," that originate deep in the Earth's mantle. Evidence for these deep structures has been sketchy, however. Now, a sophisticated array of seismometers deployed on the sea floor around Hawaii has provided the first high-resolution seismic images of a mantle plume extending to depths of at least 1,500 kilometers (932 miles).
