Dolphin Species Attempt 'Common Language'

A Guyana dolphin leaps to escape the attention of a bottlenose dolphin

From The BBC:

When two dolphin species come together, they attempt to find a common language, preliminary research suggests.

Bottlenose and Guyana dolphins, two distantly related species, often come together to socialise in waters off the coast of Costa Rica.

Both species make unique sounds, but when they gather, they change the way they communicate, and begin using an intermediate language.

That raises the possibility the two species are communicating in some way.

From The Guardian:

The Census of Marine Life is finally complete after a decade of work by 2,700 scientists from 80 countries.

It is the culmination of a decade of work by 2,700 scientists from 80 countries, who went on more than 540 expeditions into the farthest reaches of the most mysterious realm on the planet – the world's oceans.

Today, the US$650m Census of Marine Life (COML) project announced the culmination of its work, concluding that the deep is home to more than a million species – of which less than a quarter are described in the scientific literature.

From The Telegraph:

Life from outer space could be surviving on the outer fringes of the Earth's atmosphere, according to scientists who are to launch a mission to search for bacteria that could be living there.

In science fiction films the search for aliens involves travelling across the galaxy to planets millions of miles away.

But scientists believe they could be close to discovering alien life forms much closer to home – on the outer fringes of Earth's atmosphere.

Are the Ig Nobels losing their edge? The venue for this year's ceremony honouring science that "makes you laugh, then makes you think" was Harvard's Sanders Theater – a splendidly sober Victorian building that's housed many dignified graduations and historic lectures. The capacity audience was permitted to throw paper airplanes only during two designated intervals, rather than whenever the fancy took them.

Finding E.T. May Become Harder If Aliens Go Digital

Scientists may have an extra challenge when it comes to detecting alien civilizations: a time limit.

A new study suggests that intelligent aliens, if their technological progression is similar to that of humanity's, are likely to have moved away from noisy radio transmissions to harder-to-hear digital signals within a 100-year time frame. That offers Earth just a narrow window in which to pick up any signals from extraterrestrial civilizations.

As charged particles flow out from the sun, they eventually bump up against interstellar medium—the relatively empty areas between stars. These interactions "inflate" a protective bubble that shields Earth and the entire solar system from potentially harmful cosmic rays (solar system pictures).

How To Cyber Attack A Nuclear Plant

A Way To Attack Nuclear Plants -- Technology Review

Industrial computer systems are typically far less secure than they should be, experts say.

For the last few months, a sophisticated computer worm has wriggled its way between some of the most critical control systems in the world.

The timing of the worm's release, combined with several clues buried in its code, has led some experts to speculate that the worm, dubbed Stuxnet, was originally designed to sabotage an Iranian nuclear facility, possibly the enrichment plant in Natanz, roughly 180 miles south of Tehran. This week, officials in Iran confirmed that Stuxnet had been found on systems inside the plant, although they denied that it had caused any harm.

The Supernova's Secrets Cracked At Last?

Hank Childs / Lawrence Berkeley National Laboratory

From Time Magazine:

Most stars end their lives in a whimper — our own sun will almost certainly be one of them — but the most massive stars go out with an impressive bang. When that happens, creating what's known as a Type II supernova, the associated blast of energy is so brilliant that it can briefly outshine an entire galaxy, give birth to ultra-dense neutron stars or black holes, and forge atoms so heavy that even the Big Bang wasn't powerful enough to create them. If supernovas didn't exist, neither would gold, silver, platinum or uranium. The last time a supernova went off close enough to earth to be visible without a telescope, back in 1987, it made the cover of TIME.

We, Robot: What Real-Life Machines Can And Can’t Do

Photo: A lot of us teach ourselves how to reason, how to think, how to analyze new information....This has been very difficult for robots to be able to do.

From Science News:

As director of the Maryland Robotics Center, Satyandra Gupta oversees 25 faculty members working on all things robotic: snake-inspired robots, robotic swarms, minirobots for medicine and robots for exploring extreme environments on land, under the sea and in outer space. In September the Center hosted its first Robotics Day; afterward, Gupta talked robots with Science News writer Rachel Ehrenberg.

How do robots influence our lives today?

There are certain scenarios, such as manufacturing — making cars, making airplanes — where people are replacing human labor with robotic devices and the rationale is usually that it is less expensive, quality is consistent, that kind of thing. Then there are certain applications where very few humans can do the task because the skills required are so high…. Surgery would be an example. Let’s imagine that there’s a very hard-to-perform surgery that very few humans can do. Now if a robot can be trained or even teleoperated by these surgeons, then you would be able to get that performance from that robot.

From New Scientist:

Did Leonardo decipher traces of ancient life centuries before Darwin?

It was to be Leonardo da Vinci's most impressive work yet. In 1483, the Duke of Milan, Ludovico Sforza, commissioned the up-and-coming artist to create a huge bronze statue of a horse, standing over 7 metres tall. Da Vinci spent the next 10 years perfecting a full-size clay model. Sadly, it was never cast in bronze. Tonnes of the metal were needed, and Sforza ended up using the earmarked supplies to make weapons for use against invading French troops. When the French army took Milan in 1499, its archers used da Vinci's clay horse for target practice.

When it comes to bad record-keepers, no one expects the Roman Inquisition — but that's exactly what one historian discovered while trying to resolve a centuries-old controversy over the trials of Galileo.

The Roman Catholic Church's second trial of the famed Italian astronomer has come to symbolize a pivotal culture clash between science and religion.
