U-M researchers use nanoparticles to target brain cancer

...r. What's more, these nanoparticles can be used to image and track tumors as well as destroy them, according to researchers at the University of Michigan Comprehensive Cancer Center. Researchers incorporated a drug called Photofrin along with iron oxide into nanoparticles that would target cancerous brain...

Biologists probe the machinery of cellular protein factories

...other major advance with an even higher-resolution image that enables them to construct an atom-by-atom model of the ribosome. The new picture shows details never seen before and suggests how certain parts of the ribosome move during protein synthesis. A paper describing the new findings will be publishe...

Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease

...ned cutting edge "proteomics" technology, detailed image analysis, and complex computational and statistical analyses to simultaneously compare 2,000 cerebrospinal fluid proteins from 34 patients with autopsy-proven Alzheimer's disease to those of 34 age-matched controls without the disease. "Just as the...

Nerve cell software keeps track of brain change

...matical software code libraries from many years of image analysis research and added a user-friendly, database-supported interface. "We're working with a leading Australian brain research institute to thoroughly validate HCA-Vision. The results will be reported in scientific journals in the near future",...

'Nymph of the sea' reveals remarkable brood

...k Briggs from Yale. The team has made a digital image of the fossil - an ostracod (a relative of the shrimps) - which is preserved exceptionally in volcanic ash rocks in Herefordshire. Their findings are published on line in the Proceedings of the Royal Society. Professor David Siveter, of the Depart...

Radiologists attempt to solve mystery of Tut's demise

...ar initiative called the Egyptian Mummy Project to image and preserve Egypt’s mummies and to solve various mysteries about the diseases and lifestyles of ancient Egyptians. King Tutankhamun, who ascended to the throne when he was just eight years old, was mummified and buried with other ancient royals....

Elasticity imaging identifies cancers and reduces breast biopsies

Pure carbon nanotubes pass first in vivo test

...uorescence to track the nanotubes in the blood and image them in tissues under the microscope. Cherukuri said Smalley initiated several follow-up projects shortly before his passing in 2005 from lymphoma. In one, researchers are working on methods that will allow nanotubes to circulate longer following ...

Beauty and the brain

...had gone into creating the mathematically averaged image in the first place). Other work has since demonstrated that humans have similar preferences for prototypes in a wide variety of other categories, including dogs, birds, fish, cars and even watches. Yet the question "why?" has remained open. A p...

Tests for 'face-blindness' reveal disorder may not be so rare

... to indicate, as quickly as possible, whether each image they see is new or repeated. Prosopagnosics who take these tests fail to recognize repetition among the faces in the series, even as they readily identify repeated pictures of other objects. Reports of prosopagnosia date back to antiquity, although ...

Where we change our mind

... using harmless magnetic fields and radio waves to image blood flow in brain regions, which reflects activity. Importantly, Yoshida and Ishii used sophisticated statistical probabilistic analysis of the subjects' movements to overcome a major obstacle to such studies. That obstacle is that the beliefs of ...

3-D ultrasound scanner could guide robotic surgeries

...t the scanner also can be used to laparoscopically image other organs, including the spleen, liver and gall bladder. In the current study, the researchers used the scanner to identify coordinates denoting the precise location of an artificial lesion inside a type of artificial organ, or "phantom," common...

...bjects a "value" symbol that signified whether the image of a scene that followed would yield $5 or ten cents if they remembered it the next day. Then they showed the subjects the scene, and the next day tested their ability to pick the scene out of a group. The researchers found that the subjects were fa...

Movie spies on malaria parasite's sneaky behavior

...asite has evolved this complex structure. The best image to describe it is the Trojan horse, because it both transports the parasites and camouflages them," said Ménard. Like the ancient Greek warriors who hid inside a giant hollow horse to gain entry to Troy, the malaria parasites wrap themselves in a str...
