Birds of prey constrained in the beak evolution race

Science Daily - Fri, 29/04/2016 - 2:55pm
How birds' beaks evolved characteristic shapes to eat different food is a classic example of evolution by natural selection. However, new research found this does not apply to all species, and that raptors in particular have not enjoyed this evolutionary flexibility.

Doctor Ready to Perform First Human Head Transplant

Slashdot - Fri, 29/04/2016 - 2:41pm
Ross Kenneth Urken, reporting for Newsweek (edited and condensed): Italian neurosurgeon Sergio Canavero had his Dr. Strange moment when he announced he'd be able to do a human head transplant in a two-part procedure he dubs HEAVEN (paywalled, this alternate link could help) (head anastomosis venture) and Gemini (the subsequent spinal cord fusion). [...] Canavero has a plan: It's a 36-hour, $20 million procedure involving at least 150 people, including doctors, nurses, technicians, psychologists and virtual reality engineers. In a specially equipped hospital suite, two surgical teams will work simultaneously -- one focused on Valery Spiridonov (patient) and the other on the donor's body, selected from a brain-dead patient and matched with the Spiridonov for height, build and immunotype. Both patients -- anesthetized and outfitted with breathing tubes -- will have their heads locked using metal pins and clamps, and electrodes will be attached to their bodies to monitor brain and heart activity. Next, Spiridonov's head will be nearly frozen, ultimately reaching 12 to 15 degrees Celsius, which will make him temporarily brain-dead.Shouldn't it be called a body transplant? Since a person is often defined by the brain. You can read the complete procedure here.

Detecting minute nano amounts in environmental samples

Science Daily - Fri, 29/04/2016 - 2:00pm
It is still unclear what the impact is on humans, animals and plants of synthetic nanomaterials released into the environment or used in products. It’s very difficult to detect these nanomaterials in the environment since the concentrations are so low and the particles so small. Now scientists have developed a method that is capable of identifying even minute amounts of nanomaterials in environmental samples.

Supreme Court Gives FBI More Hacking Power

Slashdot - Fri, 29/04/2016 - 2:00pm
An anonymous reader cites an article on The Intercept (edited and condensed): The Supreme Court on Thursday approved changes that would make it easier for the FBI to hack into computers, many of them belonging to victims of cybercrime. The changes, which will take immediate effect in December unless Congress adopts competing legislation, would allow the FBI go hunting for anyone browsing the Internet anonymously in the U.S. with a single warrant. Previously, under the federal rules on criminal procedures, a magistrate judge couldn't approve a warrant request to search a computer remotely if the investigator didn't know where the computer was -- because it might be outside his or her jurisdiction. The rule change would allow a magistrate judge to issue a warrant to search or seize an electronic device if the target is using anonymity software like Tor."Unbelievable," said Edward Snowden. "FBI sneaks radical expansion of power through courts, avoiding public debate." Ahmed Ghappour, a visiting professor at University of California Hastings Law School, has described it as "possibly the broadest expansion of extraterritorial surveillance power since the FBI's inception."
