Scientists find fossil proof of Egypt's ancient climate

...ticular snails have a life span of between one and two years, and build their shells in a classic spiral with whatever water is available that day. The snails were preserved in calcium carbonate deposits throughout the lake. "We're using the chemistry of the water over the course of a year or two, as re...

VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain

...e gene expression patterns regulated by alcohol in two mouse strains known as B6 and D2. The two mouse strains differ in a number of behavioral responses to acute alcohol and in their predispositio...

How an AIDS-Related Cancer Unleashes Inflammation

...less urgent threat in developed countries, because two factors are needed for KS lesions ?viral infection and immunodeficiency. Effective new treatments for HIV have strikingly reduced the immunodeficiency factor in developed countries; so new cases of KS have gone down by 90 percent since 1996,?he said....

PCRM develops world's first cruelty-free insulin assay

...et on patients with type 2 diabetes. "We only had two options available to us when we began our diabetes trials," said Dr. Barnard. "One, we could use test kits with insulin antibodies grown in vivo--literally from cells injected into the abdomens of live mice--or we could use kits containing antibodies...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...phospholipid chains, a polymersome is comprised of two layers of synthetic co-polymers. Like a living cell, the polymersome membrane has a hydrophobic core. The study shows that the fluorophores evenly disperse within this core, giving rise to a nanometer-sized light-emitting structure. "These polymers ...

Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss

...the hospital the same day and will be followed for two years as part of the study, and then indefinitely. The patients were recruited from a pool of about 5,000 applicants. The implants are designed for people with retinal diseases such as macular degeneration and retinitis pigmentosa, which cause blin...

Wiley announces publication of Databasing the Brain

Expertly edited by two pioneers in this growing discipline, the text covers the basic principles and specific applications across a range of problems in brain research. Extensively illustrated throughout, this book discusses the state-of-the-art informatic tools and models...

Kinovate Life Sciences Launches Nittophase?High Performance Solid Support For Oligonucleatide Synthesis

...oods. NittoPhase?will be commercially available in two grades; NittoPhaseTOS?for high loading applications, and NittoPhaseROS?for lower loading applications. In this way, NittoPhase?offers a solution for the entire spectrum of oligonucleotide synthesis applications. “Kinovate Life Sciences aims to be a ...

Bone Density Recovers After Teens Stop Injected Contraceptive

...egan, and every six months thereafter for the next two to three years. During the course of the study, 61 women stopped using the contraceptive. The researchers found that DMPA users had a greater reduction in bone density findings than did non-users. Dr. Scholes explained that these bone density losse...

Antibiotic might fight HIV-induced neurological problems

... as yet undefined biological pathways that involve two specific proteins -- MCP-1 and p38 -- implicated in damage in neurodegenerative diseases. The MCP-1 protein, when secreted from brain cells under attack from HIV or SIV, attracts infection-fighting cells known as macrophages, which then enter the br...
