New computational microscopy technique provides more direct route to crisp images

Posted by in categories: biotech/medical, computing, information science

For hundreds of years, the clarity and magnification of microscopes were ultimately limited by the physical properties of their optical lenses. Microscope makers pushed those boundaries by making increasingly complicated and expensive stacks of lens elements. Still, scientists had to decide between high resolution and a small field of view on the one hand or low resolution and a large field of view on the other.

In 2013, a team of Caltech engineers introduced a called FPM (for Fourier ptychographic microscopy). This technology marked the advent of computational microscopy, the use of techniques that wed the sensing of conventional microscopes with that process detected information in new ways to create deeper, sharper images covering larger areas. FPM has since been widely adopted for its ability to acquire high-resolution images of samples while maintaining a large field of view using relatively inexpensive equipment.

Now the same lab has developed a new method that can outperform FPM in its ability to obtain images free of blurriness or distortion, even while taking fewer measurements. The new technique, described in a paper that appeared in the journal Nature Communications, could lead to advances in such areas as biomedical imaging, digital pathology, and drug screening.

AI Tool Using Single-Cell Data Has Promise for Optimally Matching Cancer Drugs to Patients

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

A team led by NCI researchers has developed an artificial intelligence (AI) tool that uses data from individual cells inside tumors to predict whether a person’s cancer will respond to a specific drug. Learn more about how these findings hold promise for optimally matching cancer drugs to patients:


Precision oncology, in which doctors choose cancer treatment options based on the underlying molecular or genetic signature of individual tumors, has come a long way. The Food and Drug Administration has approved a growing number of tests that look for specific genetic changes that drive cancer growth to match patients to targeted treatments. The NCI-MATCH trial, supported by the National Cancer Institute, in which participants with advanced or rare cancer had their tumors sequenced in search of genetic changes that matched them to a treatment, has also suggested benefits for guiding treatment through genetic sequencing. But there remains a need to better predict treatment responses for people with cancer.

A promising approach is to analyze a tumor’s RNA in addition to its DNA. The idea is to not only better understand underlying genetic changes, but also learn how those changes impact gene activity as measured by RNA sequencing data. A recent study introduces an artificial intelligence (AI)-driven tool, dubbed PERCEPTION (PERsonalized single-Cell Expression-based Planning for Treatments In ONcology), developed by an NIH-led team to do just this.1 This proof-of-concept study, published in Nature Cancer, shows that it’s possible to fine-tune predictions of a patient’s treatment responses from bulk RNA data by zeroing in on what’s happening inside single cells.

Researchers develop tiny, cost-effective Ti laser that fits on a chip

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

Stanford’s new tiny, cheap laser:


Researchers have achieved a potentially groundbreaking innovation in laser technology by developing a titanium-sapphire (Ti: sapphire) laser on a chip. This new prototype is dramatically smaller, more efficient, and less expensive than its predecessors, marking a significant leap forward with a technology that has broad applications in industry, medicine, and beyond.

Ti: sapphire lasers are known for their unmatched performance in quantum optics, spectroscopy, and neuroscience due to their wide gain bandwidth and ultrafast light pulses. However, their bulky size and high cost have limited their widespread adoption. Traditional Ti: sapphire lasers occupy cubic feet in volume and can cost hundreds of thousands of dollars, in addition to requiring high-powered lasers costing $30,000 each to feed it the energy it needs to operate.

Researchers discover ‘Trojan Horse’ Virus Hiding in Human Parasite

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

An international team led by researchers at the University of Toronto has found a new RNA virus that they believe is hitching a ride with a common human parasite.

The virus, called Apocryptovirus odysseus, along with 18 others that are closely related to it, was discovered through a computational screen of human neuron data — an effort aimed at elucidating the connection between RNA viruses and neuroinflammatory disease. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.

“We discovered A. odysseus in human neurons using the open-science Serratus platform to search through more than 150,000 RNA viruses” said Purav Gupta, first author on the study, recent high school graduate and current undergraduate student at U of T’s Donnelly Centre for Cellular and Biomolecular Research. “Serratus identifies RNA viruses from public data by flagging an enzyme called RNA-dependent RNA polymerase, which facilitates replication of viral RNA. This enzyme allows the virus to reproduce itself and for the infection to spread.”
