Houston establishes itself as a pioneer in regenerative medicine

Posted by in categories: biotech/medical, life extension

Inside Doris Taylor’s lab at the Texas Heart Institute are ethereal white pig hearts, stripped of their cells and now a blank slate of an organ.

Removing cells from an organ is fairly simple for scientists like Taylor. Rebuilding the organ by injecting stem cells is the tricky part.

But that’s exactly what Taylor hopes to do: grow a human heart by injecting human stem cells into a “decellularized” organ.

We’ll Soon Trust AI More Than Doctors to Diagnose Disease

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

It probably goes without saying, but medicine has improved a lot in modern times. No one would willingly go back to the days of sketchy anesthetics and experimental surgery.

We know a lot more about what ails the body and how to treat disease.

But could we do better? Sure. Some conditions yet confound doctors. Patients still suffer. As much as the situation has improved—some things haven’t changed a bit.

Atomic-scale MRI holds promise for new drug discovery

Posted by in categories: biotech/medical, computing, quantum physics

Researchers at the University of Melbourne have developed a way to radically miniaturise a Magnetic Resonance Imaging (MRI) machine using atomic-scale quantum computer technology.

Capable of imaging the structure of a single bio-molecule, the new system would overcome significant technological challenges and provide an important new tool for biotechnology and drug discovery.

The work was published today in Nature Communications, and was led by Prof Lloyd Hollenberg at the University of Melbourne, working closely with researchers at the ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) to design the quantum molecular microscope.

Brain modulyzer provides interactive window into the brain

Posted by in categories: biotech/medical, computing, neuroscience

For the first time, a new tool developed at the Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory (Berkeley Lab) allows researchers to interactively explore the hierarchical processes that happen in the brain when it is resting or performing tasks. Scientists also hope that the tool can shed some light on how neurological diseases like Alzheimer’s spread throughout the brain.

Created in conjunction with computer scientists at University of California, Davis (UC Davis) and with input from neuroscientists at UC San Francisco (UCSF), the software, called Brain Modulyzer, combines multiple coordinated views of functional magnetic resonance imaging (fMRI) data — like heat maps, node link diagrams and anatomical views — to provide context for brain connectivity data.

“The tool provides a novel framework of visualization and new interaction techniques that explore the brain connectivity at various hierarchical levels. This method allows researchers to explore multipart observations that have not been looked at before,” says Sugeerth Murugesan, who co-led the development of Brain Modulyzer. He is currently a graduate student researcher at Berkeley Lab and a PhD candidate at UC Davis.

Scholars call for probe into genome editing technology claims

Chinese biologists reiterate doubts over validity of genome editing study

A number of Chinese scientists have announced publicly that they cannot replicate the breakthrough genome editing technology NgAgo discovered by a Hebei-based researcher, Han Chunyu, urging to investigate his team for the sake of “reputation of Chinese scientists.”

After months of study, 13 biologists including Wei Wensheng and Sun Yujie from Peking University’s School of Life Science, and other biologists from prestigious institutes such as the Chinese Academy of Sciences, Zhejiang University and Shanghai Jiao Tong University, said publicly that they cannot replicate Han’s results, and called on Han to publicize his raw data.

First human clinical trial for nicotinamide riboside

In the first controlled clinical trial of nicotinamide riboside (NR), a newly discovered form of Vitamin B3, researchers have shown that the compound is safe for humans and increases levels of a cell metabolite called NAD+ that is critical for cellular energy production and protection against stress and DNA damage.

Levels of NAD+ (first discovered by biochemists in 1906) diminish with age, and it has been suggested that loss of this metabolite may play a role in age-related health decline.
