Diabetic Mice Cured With Human Stem Cells

Posted by in category: biotech/medical

Human stem cells have successfully been converted into cells that are capable of producing insulin by a team of researchers from the Washington University School of Medicine; the insulin producing cells were able to control blood sugar levels in experiments with diabetic mice.

“These mice had very severe diabetes with blood sugar readings of more than 500 milligrams per deciliter of blood — levels that could be fatal for a person — and when we gave the mice the insulin-secreting cells, within two weeks their blood glucose levels had returned to normal and stayed that way for many months,” lead researcher Jeffrey Millman, assistant professor at Washington University, said in a statement.

The research was described in the journal Nature Biotechnology and it builds upon previous work in which the researchers developed the insulin producing cells out of human stem cells but were not able to demonstrate effectiveness in animal models until now.

Mind-Reading Brain Scanners Could Give Voice to Intensive Care Patients

Posted by in categories: biotech/medical, neuroscience

What happens to people who suffer severe injuries that make it impossible for them to communicate? They are often left at the mercy of doctors and families who are obligated to make vital decisions for them. According to New Scientist, however, now there are new mind-reading brain scanners that may remedy this situation.


The new scanners use functional near-infrared spectroscopy.

Eavesdropping on “conversations” between gut stem cells and gut bacteria

Posted by in category: biotech/medical

Baltimore, MD— They say a picture is worth 1,000 words. But what about a real-time window into the complexity of the gastrointestinal system?

A new research tool allowed biologists to watch in real time the cell renewal process that keeps gut tissue healthy, as well as the interactions between bacterial species that make up the microbiome. Their work, led by Lucy O’Brien and KC Huang of Stanford University and Carnegie’s Will Ludington, was recently published by PLOS Biology.

The system, dubbed Bellymount, allowed researchers to peer into the live tissue of the fruit fly gut and better understand the many complex, overlapping processes occurring there.

Dynamic Role of the GTP Energy Metabolism in Cancers

Posted by in category: biotech/medical

O.o circa 2016.


Keio J Med. 2016;65:21. doi: 10.2302/kjm.65–001-ABST.

Rapid growing cells like tumor cells need a vast amount of energy to match their high metabolic demand. Guanine triphosphate (GTP) is one of major cellular metabolites and served as a building block for RNA and DNA as well as an energy source to drive cellular activities such as intracellular trafficking, the cell migration and translation. However, how cancer cells regulate GTP energy levels to adapt for their high demand remain largely unknown yet. In addition, how cells detect GTP levels remains unknown. In this seminar, I will introduce our recent findings that uncover dramatic change of GTP metabolism in cancer cells and a GTP sensing kinase that regulate metabolism for tumorigenesis.(Presented at the 1918th Meeting, March 3, 2016).

Is Sex for Reproduction About to Become Extinct?

Posted by in categories: bioengineering, biotech/medical, genetics, sex

As the coming genetic revolution plays out, we’ll still have sex for most of the same reasons we do today. But we’ll increasingly not do it to procreate.


Another rocket booster will be the application of gene editing technologies like CRISPR to edit the genomes of pre-implanted embryos or of the sperm and eggs used to create them. Just this week, Chinese researchers announced they had used CRISPR to edit the CCR5 gene in the pre-implanted embryos of a pair of Chinese twins to make them immune to HIV, the first ever case of gene editing humans and a harbinger of our genetically engineered future. The astounding complexity of the human genome will put limits on our ability to safely make too many simultaneous genetic changes to human embryos, but our ability and willingness to make these types of alterations to our future children will grow over time along with our knowledge and technological ability.

Blood test method may predict Alzheimer’s protein deposits in brain

Posted by in categories: biotech/medical, life extension, neuroscience

Researchers report an advance in the development of a blood test that could help detect pathological Alzheimer’s disease in people who are showing signs of dementia. This approach could be less invasive and less costly than current brain imaging and spinal fluid tests. The blood test detects the abnormal accumulation of a form of tau protein known as phosphorylated-tau-181 (ptau181), which is a biomarker that suggests brain changes from Alzheimer’s. The study, funded by the National Institutes of Health, was published on March 2 in Nature Medicine.

Over the past 15 years, research advances in the development of biomarkers like tau protein have enabled investigators to more accurately diagnose Alzheimer’s disease, select research participants, and measure response to investigational therapies. Tau and other biomarkers can be detected with PET scans of the brain and lab tests of spinal fluid. However, PET imaging is expensive and involves radioactive agents, and spinal fluid tests require spinal taps, which are invasive, complex and time-consuming. Simpler biomarker tests are still needed.

“The considerable time and resources required for screening research participants with PET scans and spinal taps slow the pace of enrollment for Alzheimer’s disease treatment studies,” said Richard J. Hodes, M.D., director of NIH’s National Institute on Aging (NIA), which funded much of the study. “The development of a blood test would enable us to rapidly screen a much larger and more diverse group of volunteers who wish to enroll in studies.”

Alibaba’s new AI system can detect coronavirus in seconds with 96% accuracy

Posted by in categories: biotech/medical, robotics/AI

Chinese technology giant Alibaba recently developed an AI system for diagnosing the COVID-19 (coronavirus).

Alibaba’s like Amazon, Microsoft, a video game company, and a nation-wide healthcare network all rolled into one with every branch being fed solutions from the company’s world-class AI department.

Per a report from Nikkei’s Asian Review (h/t TechSpot), Alibaba claims its new system can detect coronavirus in CT scans of patients’ chests with 96% accuracy against viral pneumonia cases. And it only takes 20 seconds for the AI to make a determination – according to the report, humans generally take about 15 minutes to diagnose the illness as there can be upwards of 300 images to evaluate.
