A species of tiger moth can evade hungry bats by making extra-loud clicks that jam the bats' ability to echolocate. In a study published in Science, researchers found that as long as moths could emit clicks, the bats could not catch them. However, when the scientists pierced a small hole in the moths' vibrating tymbals, the muffled moths were promptly eaten. More info and video at Wired.com.
NASA's Lunar Reconnaissance Orbiter (LRO) has captured images from five of the six Apollo sites, the space agency reported Friday. The photos show the Apollo missions' lunar module descent stages sitting on the moon's surface, with distinct shadows making the modules' locations evident. LRO should see the Apollo 12 site, the only one not yet photographed, in the coming weeks. More at NASA.
The US military is experimenting with creating half-robot, half-insect "cybugs," that could function as spies and fly undetected into enemy locations. They will attempt to surgically implant microchips into insects...
Astronomers have found the most ancient and distant supernova-- a star that detonated just 3 billion years after the Big Bang. The new technique they used to find it may reveal many other ancient supernovae...
A sunspot that suddenly appeared on July 3rd, 2009 was thought by some to support the crop circle prediction that there'd be a major solar storm today, July 7th. However, Spaceweather.com is reporting that Sunspot 1024 is decaying...
DARPA-contractor AeroVironment has developed a tiny drone that mimics the wing movement of a hummingbird, allowing it fly about and hover just like the actual bird...
Dean Warsing has posted a set of video clips showing various aerial phenomena captured through Night Vision. In a number of the clips, they point a laser at objects in the sky...
A recent photo shows an Air Force F-22 Raptor as it executes a supersonic flyby over the deck of an aircraft carrier in the Gulf of Alaska. The breaking of the sound barrier is sometimes accompanied by a visual phenomenon referred to as a "vapor cone"...
Last week's guest with George Knapp, John Alexander, an expert in non-lethal weapons, claimed that no one has ever been killed by a Taser. George received a number of emails to the contrary. In this letter, Alexander responds...
A new humanoid robot that can express emotions was unveiled in Tokyo on Tuesday. Named KOBIAN, it's able to express a variety of emotions through "actuators" that allow its face and body to move in different ways...

Astronomers may have discovered the first planet in another galaxy. Through a technique called microlensing, they detected a world about six times the size of Jupiter...
SignalTheorist.com captured this beautiful long-exposure shot of a Roomba robotic vacuum as it ran through its cleaning cycle. What appears to be a seemingly random and inefficient pattern actually ends up thoroughly covering the entire floor area.
Some of the technology Nick Begich discussed in the 6/3/09 show is featured in an article on Wired's Danger Room.
The new ABC special "Earth 2100", airing Tuesday night, looks at how the combination of population growth, resource depletion, and climate change could have catastrophic consequences.
While vacuuming may have succumbed to the expanse of robots, most of today's challenges and chores still await their mechanical "helping hand."
The new Iceman photoscan website allows you to explore the body of the famous mummy known as Otzi the Iceman in amazing detail, including 3D images. Discovered in a glacier in the Alps in 1991, Otzi is thought to have died around 3300 BC.
A 47-million-year-old fossil of a primate may be the long sought missing link between humans and apes. Nicknamed "Ida," the lemur-like creature had opposable thumbs, and fingernails instead of claws.
Two spacewalking astronauts, John Grunsfeld and Drew Feustel, spent six and a half hours on Saturday installing a new high-tech instrument on Hubble as well as performing complex repairs to the space telescope's broken planetary camera.
Amateur Astronomer Thierry Legault snapped this one of kind photograph of Space Shuttle Atlantis, in silhouette against the Sun, on its way to upgrade the Hubble Space Telescope.
Astronauts aboard the shuttle Atlantis latched onto the Hubble today using a robotic arm. They are preparing for a series of spacewalks to repair and upgrade the telescope, which is pictured here as seen from the shuttle.
