Leading reason for corneal transplants comes into focus

...lier Fuchs gene-hunting studies. The Hopkins group tracked down its first FCD-related gene in a Virginia family with multiple, early onset cases. That gene, labeled COL8A2, was mapped to chromosome 1. Prior to that, a large Indiana family with FCD, including a boy of 10, led the team to yet another gene ...

Innovative movies show real-time immune-cell activity within tumors

...able to peer inside living tissues. The microscope tracked and recorded the movements in three dimensions over time of T cells in a transgenic mouse developed by Weninger and Ulrich von Andrian at Harvard Medical School in which the cells fluoresce green. In addition, for this study, tumor cells in the mice ...

Pure carbon nanotubes pass first in vivo test

... is what we expected to find." The study, which tracked where the nanotubes went within 24 hours of being injected, also revealed trace amounts of nanotubes in the kidneys ?another common expulsion route for drugs. There was no evidence that nanotubes remained in other tissues in the body. Nanotubes ar...

Cell death following blood 'reflow' injury tracked to natural toxin

...ut what triggers the death switch, the researchers tracked PAR-polymer's journey after cells made it. After 15 minutes, PAR-polymer hadn't gone anywhere. But after 30 to 60 minutes, the researchers discovered that much of it traveled right to areas where the switch normally resides. The fate of the cell is...

Breastfeeding boosts mental health

Cutting calories slightly can reduce aging damage

... when aging-related damage happens, UF researchers tracked levels of biomarkers - chemicals and molecules present in the liver - in groups of rats. The liver, a crucial organ for maintaining good health during aging, cleans the blood and helps regulate the body's immune system. The researchers also plan to a...

Dragonfly migration resembles that of birds, scientists say

They have also demonstrated the accelerating pace of the boom and bust pattern of exploitation, a characteristic dynamic of unregulated high-value c...

Pollution threatens coral health by preventing lesions from healing, UCF study shows

...ege of Charleston and Nova Southeastern University tracked how quickly coral regenerated lost tissue from lesions they created while collecting samples. Scientists have long been concerned about declining coral reef health off the southeastern Florida coast, in the Florida Keys and worldwide. The World Res...

Ecologists home in on how sperm whales find their prey

...erm whales with suction cups. The whales were then tracked acoustically with a towed hydrophone array. The researchers used the tags to record the sounds that sperm whales produce while foraging. As sperm whales descended from the surface, they emitted a regular series of "clicks". When the whales reach the...
