New gene clue to ovarian cancer

New gene clue to ovarian cancer | JIS-Biology | Scoop.it
UK scientists have found a gene in mice that, if faulty, may increase the risk of ovarian cancer.
Sherriden Masters's insight:

Great article which reports the efforts of Cancer Research UK findings that the "Helq" gene may be related to an increased probability of developing ovarian cancer. The article shows how these studies can be rapidly evaluated in humans, by screening ovarian cancer sufferers, or those with a high likelihood of developing it, for the Helq gene.

 

Thank you Izzah

Tiny ‘brains’ built from stem cells could offer insight into genetic brain disorders

Tiny ‘brains’ built from stem cells could offer insight into genetic brain disorders | JIS-Biology | Scoop.it

"Researchers have, for the first time, used stem cells to build structures that resemble three-dimensional brain-like tissue, and the result could be of great use to medical researchers"

Sherriden Masters's insight:

This article describes how researchers have created tiny "cerebral organids" that resemble the early human brain. Fascinating article offering an insight into the cutting edge of neuroscience.

Thank you Elssa

Scientists Put Backpacks on Dragonflies to Track Their Brains in Flight | Wired Science | Wired.com | JIS-Biology | Scoop.it
The brain of a dragonfly has to do some serious calculations -- and fast -- if it hopes to nab a mosquito or midge in midair.
Sherriden Masters's insight:

Such an fascinating experiment, with significant challenges! The power harvesting using antenna, rather than having batteries, is brilliant. The labs they used, and the implications for studying neuron firing, are really interesting too! 

Also a little video on the site.

Sherriden Masters's insight:

Very interesting video, on the ways in which a smart phone may act as a medical diagnostic tool.  The implications for reduction in healthcare costs is significant, but how will self diagnosis impact treatment?

 

Dr Dr , my phone tells me I’m dead etc.....

Gene therapy to repair failing hearts starts trial - health - 30 April 2013 - New Scientist

Gene therapy to repair failing hearts starts trial - health - 30 April 2013 - New Scientist | JIS-Biology | Scoop.it
A pioneering treatment to deliver a vital protein to damaged hearts could restore proper beating

 

Doctors will inject participants with harmless viruses that ferry a gene calledSERCA2a into their heart muscle. The gene codes for a protein that recycles calcium within heart muscle cells, vital for driving each heartbeat and priming the next one.

 

In damaged cells, this recycling is impaired. By loading new copies of the gene the aim is to compensate for this decline. "The gene therapy will reset the calcium control," says Lyon.

Sherriden Masters's insight:

Cutting edge article on real applications of Gene therapy

Sherriden Masters's insight:

Incredible article from the same research team who cloned mice from dna frozen for 16 years.  The press release is here, and below are a few more "popular media" links.  The researcher say that this would be an ideal method for rearing cattle for better, more consistant meat supply.

Baby With H.I.V. Is Reported Cured | JIS-Biology | Scoop.it
The baby, born in rural Mississippi, was treated aggressively with antiretroviral drugs starting around 30 hours after birth; if further study shows this treatment works, it will almost certainly be recommended globally.
Sherriden Masters's insight:

An article you must read, as much of a game changer as the Berlin Patient. By using of aggressive retroviral therapy, scientists in Mississppi seem to have rolled back the onset of HIV in a newborn.

Super Sugar Keeps Naked Mole Rats Cancer-Free | Wired Science |

Super Sugar Keeps Naked Mole Rats Cancer-Free | Wired Science | | JIS-Biology | Scoop.it
Although they are quite ugly and confined to a life underground, naked mole rats have at least one attribute that other animals, even humans, might aspire to: They don't get cancer.
Sherriden Masters's insight:

Very elegant and ingenious scientific methods deduce that a sugar involved in cell to cell bonding (Hyaluronan) seems to protect naked mole rats from cancer, even when cancer is actively stimulated. Great, accessible article, especially interesting when discussing tumour suppressor genes and oncogenes.

Interesting choice of headline, using “Mutant” where the fact is that these creatures are not made like this by chance or accident, but by careful design and manipulation. Guess it’s all in the perspective?

Molecular trigger for Alzheimer's disease identified

Molecular trigger for Alzheimer's disease identified | JIS-Biology | Scoop.it
Researchers have pinpointed a catalytic trigger for the onset of Alzheimer's disease -- when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain.
Sherriden Masters's insight:

"They believe the breakthrough is a vital step closer to increased capabilities for earlier diagnosis of neurological disorders such as Alzheimer’s and Parkinson’s, and opens up possibilities for a new generation of targeted drugs, as scientists say they have uncovered the earliest stages of the development of Alzheimer’s that drugs could possibly target"

Scientists are looking at ways to lower the global temperature by removing greenhouse gases from the air. Could super-absorbent fake leaves be the answer?
Sherriden Masters's insight:

Amazing article and research regarding carbon capture. researchers at Columbia University have designed an artificial tree that passively soaks up carbon dioxide from the air using “leaves” that are 1,000 times more efficient than true leaves that use photosynthesis.

Amazing claim, read it and be impressed. I do sincerely hope they get cheaper (US$20,000 a pop at the moment)
