Facility for Rare Isotope Beams

Posted by in categories: biotech/medical, education, employment, security

FRIB) will be a scientific user facility for the Office of Nuclear Physics in the U.S. Department of Energy Office of Science (DOE-SC). FRIB is funded by the DOE-SC, MSU and the State of Michigan. Supporting the mission of the Office of Nuclear Physics in DOE-SC, FRIB will enable scientists to make discoveries about the properties of rare isotopes (that is, short-lived nuclei not normally found on Earth), nuclear astrophysics, fundamental interactions, and applications for society, including in medicine, homeland security, and industry.

This video — The Facility for Rare Isotope Beams at MSU — explains the history of FRIB, its role in research and education, and its future in rare-isotope discoveries. It includes an animated sequence to help viewers understand what FRIB is about.

Employment opportunities: FRIB is looking for engineers, physicists, and other talented professionals to build the world’s leading rare isotope facility.

Mental Candy Is Also Unhealthy

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

We take a somewhat humorous look at the messaging and the comfort stories people tell themselves to distract themselves from seeing why age-related diseases and dying from them is a problem that needs solving.


Here’s what might be considered a paradox: right now, the Facebook page of Death Cafe—a place where you go to talk about death—is a rather lively place, whereas pages about life extension are comparatively rather dead places. This screenshot shows the activity of a Death Cafe post:

The pharmacy of the future? Personalized pills, 3D printed at home

Posted by in categories: 3D printing, biotech/medical

We need to change how we prescribe drugs, says physician Daniel Kraft: too often, medications are dosed incorrectly, cause toxic side effects or just don’t work. In a talk and concept demo, Kraft shares his vision for a future of personalized medication, unveiling a prototype 3D printer that could design pills that adapt to our individual needs.

Bill Gates warns that nobody is paying attention to this state-of-the-art scientific technology that could make inequality even worse

Posted by in categories: bioengineering, biotech/medical

Gene editing is one of the most promising new approaches to treating human diseases today.

It also raises “enormous” ethical questions, Bill Gates recently warned, and “could make inequity worse, especially if it is available only for wealthy people.”

“I am surprised that these issues haven’t generated more attention from the general public,” he said in a December blog post, adding that “this might be the most important public debate we haven’t been having widely enough.”

Scientists could engineer a spicy tomato. Is it worth it?

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

Spicy food is popular the world over, but the active ingredient that makes food taste “hot”—capsaicinoids, a group of chemical compounds has useful properties beyond making food taste delicious. However, the plants that make them (the chili pepper family, or Capsicum) are small and have relatively low yields. A new paper published today in the journal Trends in Plant Science proposes an alternative: engineering tomato plants to produce capsaicinoids. If all goes well, someday, you could enjoy a spicy tomato, or even be treated with capsaicinoids extracted from one.

The paper, written by a group at Brazil’s Federal University of Viçosa, builds on recent work that showed the tomato has all the genetic information it needs to produce capsaicinoids. “We know that all the genes are there, but in the tomato they are silent,” study author Agustin Zsӧgӧn says. His paper proposes a method for using gene-editing techniques to activate the genetic machinery in the tomato that tells it how to produce capsaicinoids, transforming the plant into both a “biofactory” that could produce larger amounts of the chemicals than it’s currently possible to grow and a spicy snack.

Tomatoes have capsaicinoid genetic pathways like peppers because the two South American plants are related. “In our lab, we work with both species,” Zsӧgӧn says. Last year, his team used gene editing to “domesticate” a wild tomato in just a few generations, engineering the strain to produce larger fruit, and greater quantities of it, than in the wild. This kind of process is how we ended up with the crops we eat today—early farmers planted the offspring of the most fruitful plants of each generation, enabling their genetic survival. CRISPR-Cas9 is just a shortcut.

Intraoperative detection of blood vessels with an imaging needle during neurosurgery in humans

Posted by in categories: biotech/medical, neuroscience

Intracranial hemorrhage can be a devastating complication associated with needle biopsies of the brain. Hemorrhage can occur to vessels located adjacent to the biopsy needle as tissue is aspirated into the needle and removed. No intraoperative technology exists to reliably identify blood vessels that are at risk of damage. To address this problem, we developed an “imaging needle” that can visualize nearby blood vessels in real time. The imaging needle contains a miniaturized optical coherence tomography probe that allows differentiation of blood flow and tissue. In 11 patients, we were able to intraoperatively detect blood vessels (diameter, 500 μm) with a sensitivity of 91.2% and a specificity of 97.7%. This is the first reported use of an optical coherence tomography needle probe in human brain in vivo. These results suggest that imaging needles may serve as a valuable tool in a range of neurosurgical needle interventions.

Stereotactic brain biopsies are a minimally invasive procedure used to obtain samples of intracranial tissue for diagnostic purposes, most commonly related to brain tumors. Approximately 80,000 new cases of primary brain tumor are diagnosed, and 14,000 brain biopsies are performed each year in the United States (1, 2). Hemorrhage is the most frequent and devastating complication associated with this procedure. Perioperative hemorrhage is associated with rates of transient and permanent morbidity of 1.7 to 8.5% and 1.4 to 4.8%, respectively, and mortality rates of 0.6 to 2.8% (37).

The standard clinical practice is to identify blood vessels at risk of injury on preoperative imaging, using either contrast-enhanced magnetic resonance imaging (MRI) or x-ray computed tomography. Frameless stereotactic navigation techniques, guided by preoperative imaging, are then used to direct the biopsy needle trajectory to sample the target lesion, while avoiding vasculature or eloquent brain tissue (8).
