What secrets of the sea have dolphins been waiting to tell us? We may soon find out (hopefully not just tuna jokes). New Scientist reports:

A diver carrying a computer that tries to recognize dolphin sounds and generate responses in real time will soon attempt to communicate with wild dolphins off the coast of Florida. If the bid is successful, it will be a big step towards two-way communication between humans and dolphins.
Since the 1960s, captive dolphins have been communicating via pictures and sounds. In the 1990s, Louis Herman of the Kewalo Basin Marine Mammal Laboratory in Honolulu, Hawaii, found that bottlenose dolphins can keep track of over 100 different words. They can also respond appropriately to commands in which the same words appear in a different order, understanding the difference between “bring the surfboard to the man” and “bring the man to the surfboard”, for example.
But communication in most of these early experiments was one-way, says Denise Herzing, founder of the Wild Dolphin Project in Jupiter, Florida.
After years of forgetting your friends’ numbers because they were saved on your cellphone, new technology allows you to make calls by simply thinking the phone number. Via MIT Technology Review:

Researchers in California have created a way to place a call on a cell phone using just your thoughts. Their new brain-computer interface is almost 100 percent accurate for most people after only a brief training period.
The system was developed by Tzyy-Ping Jung, a researcher at the Swartz Center for Computational Neuroscience at the University of California, San Diego, and colleagues. Besides acting as an ultraportable aid for severely disabled people, the system might one day have broader uses, he says. For example, it could create the ultimate hands-free experience for cell-phone users, or be used to detect when drivers or air-traffic controllers are getting drowsy by sensing lapses in concentration.
New York Republican Peter King has made national headlines in 2011 with his congressional hearings on the (dis)loyalties of Muslim-Americans. However, that is not the only trouble he has been stirring up. The media largely missed his recent introduction of House Resolution 607, which would auction off for commercial use the frequency bands used by amateur radio operators (for the purpose of funding the use of other frequency bands by the police in emergencies). The American Radio Relay League fumes:

On February 10, 2011, Rep. Peter King (R-NY), Chairman of the House Homeland Security Committee, introduced H.R. 607, the “Broadband for First Responders Act of 2011,” which has been referred to the House Energy and Commerce Committee (which handles telecommunications legislation).
The Bill provides for the allocation of the so-called “D-Block” of spectrum in the 700 MHz range for Public Safety use. HR 607 uniquely, provides for the reallocation of other spectrum for auction to commercial users, in order to offset the loss of revenue that would occur as the result of the allocation of the D-Block to Public Safety instead of commercial auction.
Lightspeed Magazine has a fun rundown of humanity’s historical efforts to send space transmissions to whatever intelligent life might be out there. The whole endeavor is slightly desperate and pathetic — “The chances of an alien civilization having the means, motive, and opportunity to catch any of these messages are slim; certainly it’s not likely that humanity will last long enough to catch any return messages.” Still, it’s nice knowing that Morse code and theremin music has been beamed into the heavens.

1. The Morse Message (1962)
This audio salute, one of the first radio signals intended specifically for interstellar intelligence, was meant as a test of the new Evpatoria Planetary Radar (EPR). In November 1962, the Unique Korenberg Telescope Array transmitted the greeting towards Venus, using simple Morse Code. Given the location of Venus in November 1962, the message is even now winging its way towards Libra.
Message Content: The words “MIR,” “LENIN,” and “SSSR,” in Morse.
In case video chat wasn’t realistic enough for you. Via Brisbane Times:
Japanese researchers say they have developed a human-shaped mobile phone with a skin-like outer layer that enables users to feel closer to those on the other end.
“The mobile phone may feel like the person you are talking to,” the Advanced Telecommunications Research Institute International (ATR) said in a press release, describing the gadget as a “revolutionary telecom medium”.
The project is a collaboration between Osaka University, the mobile telephone operator NTT DoCoMo and other institutes.
They hope to put it into commercial production within five years by adding image and voice recognition functions.

Just more evidence that non-human animal species have deeper intelligence than we give them credit for, and communicate in ways to which we are oblivious. Wired Science discusses a secret form of bird-language, which we should probably learn if we hope to foil the coming avian takeover:

The discovery of messages in raptors’ nests has raised the possibility that many bird species encode signals into these structures, with seemingly decorative flourishes actually full of meaning.
Among black kites, scraps of white plastic are used to signal territorial dominance. To other kites, the scraps are a warning sign. To humans, they hint at an unappreciated world of animal communication.
“It’s probably very common that other bird species decorate their nests in ways compatible with what we found,” said Fabrizio Sergio, a biologist at the Doñana Biological Station in Spain. “And not only birds, but fish and mammals.”
A few species, such black wheateaters and bowerbirds, are already known to use nest design in courtship displays.
If you’re going to rely on a phone app to keep your children safe, I suppose this is a good one. BBC News reports:
A mobile phone application which claims to identify adults posing as children is to be released.
The team behind Child Defence says the app can analyse language to generate an age profile, identifying potential paedophiles.
Isis Forensics developed the tool after parental concerns over children accessing sites on their mobiles.
But child protection experts warned against such technology lulling people into thinking they are safe.
Child Defence project leader James Walkerdine, based at Lancaster University, said: “This software improves children’s chances of working out that something isn’t right.
