Promising new pancreatic cancer treatment moves forward
Posted by Paul Battista in categories: biotech/medical, genetics
A study published today in the journal Nature Medicine led by researchers at Huntsman Cancer Institute (HCI) at the University of Utah (U of U) describes a new therapeutic approach with potential for patients with pancreatic cancer. These researchers discovered a combination drug therapy that may effectively combat the disease. HCI researchers first observed anti-cancer impacts in a laboratory setting and, subsequently, in its first use in a human patient.
The study has already progressed to a clinical trial that is now open at HCI and will soon be open at other sites in the United States. Details about the clinical trial, called THREAD, are available under National Clinical Trial Number 03825289. The combination therapy uses two drugs already approved for use by the Food and Drug Administration for other diseases, including cancer. The new drug combination is administered through pills taken orally.
Pancreatic tumors are characterized by mutations in a gene called KRAS. When KRAS is mutated in this way, it sends constant signals that promote abnormal cell division and growth in cancer cells. As a result, tumors grow out of control. At the same time, like all cells, pancreatic cancer cells must recycle their components to provide building blocks for new growth in an essential cell function known as autophagy. Previous studies to combat pancreatic cancer that were focused either on the role of KRAS or on impacting autophagy were not effective.

First CRISPR therapy administered in landmark human trial
Posted by Quinn Sena in categories: bioengineering, biotech/medical
The first confirmed CRISPR gene editing clinical trial to take place outside of China is officially underway, after pharmaceutical companies CRISPR Therapeutics and Vertex revealed a human patient has been administered the experimental treatment targeting a rare blood disease.
In the world of social media, this is just the most recent panic over children’s time on places like Youtube. however, it’s important to note that many of these things ARE just hoaxes. As the article mentions, this hoax plays on the guilt some parents have over how much time their children spend on computer screens.
The real “Momo Challenge” is the terror of parenting in the age of YouTube. Here’s the truth of what we know.

Rejuvenating Aged Brains by Waking Up Dormant Stem Cells
Posted by Steve Hill in categories: biotech/medical, neuroscience
Researchers from the University of Luxembourg and the German Cancer Research Center have rejuvenated stem cells in the brains of old mice. The rejuvenated stem cells appear to improve regeneration in areas of damaged or diseased brain tissue.
A new way to model stem cells
A new study that was published in the journal Cell sheds light on why many stem cell populations in aged brains stop dividing and enter a dormant state known as quiescence. Quiescent stem cells have ceased to divide, so they no longer support the tissues of which they are part and play no role in regenerating damaged tissue by supplying fresh cells to replace losses. As we age, an increasing number of stem cells, not just in the brain, enter this quiescent state and impair our ability to heal injury and recover from diseases.

Linking bacterial populations with health
Posted by Xavier Rosseel in categories: biotech/medical, food, health
The biggest source of variability in the microbiome is the person-to-person variability. It’s a problem if you’re looking for causality. That’s a red flag word for us – causality – meaning something about the bacterial community causes some disease. You actually don’t know whether it’s the bacteria or whether the bacteria are a sign of something that happened before. It’s very much individualized, so everybody’s history matters.
We are all teeming with bacteria that help us digest food or fight disease, but two people might play host to a very different array of bacteria due to diet, where they live, hobbies or even medical histories.
As a result, scientists have struggled to understand which bacteria are linked to disease and which protect against it. Studies comparing people’s bacterial companions – known as the microbiome – to explore what that variation means might disagree because they analyzed different groups or didn’t sample enough people.

Exploring China’s latest space ambitions
Posted by Michael Lance in categories: solar power, space, sustainability
China says it is working to develop a solar energy plant in space that could one day beam enough power back to Earth to light up an entire city.
If scientists can overcome the formidable technical challenges, the project would represent a monumental leap in combating the Earth’s addiction to dirty power sources which worsen air pollution and global warming.
A space-based solar power station could also provide an alternative to the current generation of earthbound and relatively ineffective renewable energy sources.
