Genomic Analysis Uncovers New Targets for HIV Vaccine

...g their cohorts of carefully selected patients and using the latest in genome-wide screening technology, 18 months to discover the three genes, that together greatly increase our knowledge of why patients differ in how well they can control the virus that causes AIDS. These findings represent only the fir...

Research identifies protein that signals flowering in squash plants

...ystem. Next, heterografting studies were conducted using flowering Cucurbita maxima (pumpkin) stocks (the stock is the portion below the graft union containing the roots) grafted to non-induced, LD-grown C. moschata scions (the portion above the graft union). These experiments led to flowering of the C. mo...

Enzyme delivered in smaller package protects cells from radiation damage

...D enzyme into mouse hematopoietic progenitor cells using a newly constructed gene therapy vector called a "minicircle" plasmid. To determine if the cells transfected with the MnSOD minicircle plasmid retained radioprotective capacity, they irradiated those cells as well as another cell line transfected ...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...e Eastman Department of Dentistry and an expert on using a class of viruses known as lentiviruses for use in gene therapy. The team used a lentivirus to boost levels of IL-1 beta in select brain regions of its engineered mouse, then applied the technology in mice specially designed to develop Alzheimer’s d...

Soils offer new hope as carbon sink

...richar alone was about as beneficial for yields as using nitrogen fertiliser only. "And that is without considering the other benefits of agrichar." Regarding soil chemistry, Dr Van Zwieten said agrichar raised soil pH at about one-third the rate of lime, lifted calcium levels and reduced aluminium tox...

Math that powers spam filters used to understand how brain learns to move our muscles

...visually track rapid flashes of light. Experiments using such rapid eye movements, or saccades, are a staple in studying how the brain controls movement. Initially, the animal learner made large errors, but also stored the information about its mistakes in a memory bank so it could adapt and make more a...

CSIRO scientists join fight to save 'Tassie devil'

...Church and his team will look to extend their work using the Australian synchrotron infrared beam line when it comes on-line later this year. Steve Marvanek, Spatial Data Analyst at CSIRO Land and Water, integrated historical wildlife spotlight data, devil monitoring data and geo-referenced reports of d...

Research team identifies new Alzheimer's gene

... organizations contributed to the genome-wide scan using Affymetrix microarray technology. The team screene...r, it paves the way for even more advanced studies using larger sample populations, more powerful array chips that can distinguish more genetic markers, and ...

Envisat captures first image of Sargassum from space

...ed has been detected from space for the first time using optical radiance data from the Medium Resolution I...for climate modellers. The discovery was made using the MERIS maximum chlorophyll index (MCI) which provides an assessment of the amount of chlorophyll ...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

.... They then "back translated" the protein sequence using a computer program to change the parasite gene sequence − which combines nucleotide base pairs in a way that is found in no other life form − into one that could be "read" by yeast. The yeast are then able to produce the PfMDR1 protein, in its pr...

Loss of stem cells correlates with premature aging in animal study

... Yaroslava Ruzankina, and Amma Asare are currently using this mouse model to discover compounds that preserve stem cells and may, consequentially, suppress aging. ...

Pesticides choke pathway for nature to produce nitrogen for crops

.... The paper in PNAS reports their in-vivo findings using real plants and bacteria. None of the chemicals used in the research, including PCP, proved to be toxic to either the plants or bacteria, Fox said, "but PCP was unique in that it inhibited both seed germination and nitrogen fixation." More than 20...

U-M researchers discover gene switched off in cancer can be turned on

...the development of cancer cells can be switched on using drugs, report researchers from the University of Michigan Comprehensive Cancer Center. The finding could lead to a new class of targeted cancer therapies with potential to benefit many different cancer types. Popular new drugs such as Herceptin and ...

Now, self-healing materials can mimic human skin, healing again and again

...ials, the researchers begin by building a scaffold using a robotic deposition process called direct-write assembly. The process employs a concentrated polymeric ink, dispensed as a continuous filament, to fabricate a three-dimensional structure, layer by layer. Once the scaffold has been produced, it is...

Researchers examine carbon capture and storage to combat global warming

...he added. ''Maybe we have another hundred years of using fossil fuels, and then we'll be on to better and smarter things, one hopes. If we're going to be creating greenhouse gases for another hundred years, it's a huge problem right now, so you have to get on this point. But nonetheless, our dependence on ...

Undergraduate research shows leaderless honeybee organizing

... The researchers document that the workers stop using the vibration signal when the queen flies and leaves the nest with the swarm. Piping, however, continues in the swarm, as the bees need to make the queen fly again once a new nest site has been selected. “Drew Pierce did this project last summe...

Australian wins prestigious prize in biodiversity informatics
