Dolphins form life raft to help dying friend

Everybody's favourite cetacean just got a little more lovable. For the first time, dolphins have been spotted teaming up to try to rescue an injured group member. The act does not necessarily mean dolphins are selfless or can empathise with the pain of their kin, however.

Kyum Park of the Cetacean Research Institute in Ulsan, South Korea, and colleagues were surveying cetaceans in the Sea of Japan in June 2008. They spent a day following a group of about 400 long-beaked common dolphins (Delphinus capensis).

In the late morning they noticed that about 12 dolphins were swimming very close together. One female was in difficulties: it was wriggling and tipping from side to side, sometimes turning upside-down. Its pectoral flippers seemed to be paralysed.

Life raft

The other dolphins crowded around it, often diving beneath it and supporting it from below. After about 30 minutes, the dolphins formed into an impromptu raft: they swam side by side with the injured female on their backs. By keeping the injured female above water, they may have helped it to breathe, avoiding drowning.

Arizona bill would compel hospitals to check immigration status

By Cindy Carcamo
January 26, 2013, 6:00 a.m.
Under a bill introduced this week in Arizona, hospital staffs would be compelled to check whether uninsured patients are in the country illegally.

If the patients can't provide proof that they are in the country legally, hospital staff would have to call federal immigration officials or local law enforcement. The bill by state Rep. Steve Smith also would require hospital officials to file annual reports of how many people they treated who were in the country illegally.

Smith, a Republican from Maricopa, was not available for comment, but has said that H.B. 2293 is designed to track how many people who are in the country illegally receive free medical care in the state. The aim, he has said, is not to withhold care but to collect information.

Immigrant rights organizations say the bill is misguided, targets immigrants and essentially requires hospital workers to police immigration.

In Orion, There Really is a Hole in the Sky



A new image from ESO’s APEX instrument shows a cloud of gas and dust in the Orion region. Image credit: ESO

When astronomers see dark regions in nebula in visible light, they know there’s something going on. There’s got to be some kind of star forming activity pumping out material that obscures the view to the newly forming starts. Switch to infrared and you can peer through that intervening dust to see the young stars at work.

Astronomers using the European Southern Observatory’s Atacama Pathfinder Experiment (APEX) telescope in Chile were surprised to see a dark region in the nebula NGC 1999, even in infrared, when the cause of the dark region should have been apparent.

Ooo, mystery.

Curiosity’s Robotic Arm Camera Snaps 1st Night Images



Image caption: This image of a Martian rock illuminated by white-light LEDs (light emitting diodes) is part of the first set of nighttime images taken by the Mars Hand Lens Imager (MAHLI) camera at the end of the robotic arm of NASA’s Mars rover Curiosity. The image was taken on Jan. 22, 2013, after dark on Sol 165. It covers an area about 1.3 inches by 1 inch (3.4 by 2.5 centimeters). Credit: NASA/JPL-Caltech/MSSS


Curiosity’s high resolution robotic arm camera has just snapped the 1st set of night time images of a Martian rock of the now 5 1/2 month long mission – using illumination from ultraviolet and white light emitting LED’s. See the images above and below.

The Mars Hand Lens Imager (MAHLI) camera is located on the tool turret at the end of Curiosity’s 7 foot (2.1 m) long robotic arm.
MAHLI took the close-up images of a rock target named “Sayunei” on Jan. 22 (Sol 165), located near the front-left wheel after the rover had driven over and scuffed the area to break up rocks in an effort to try and expose fresh material, free of obscuring dust.
