Whole exome sequencing predicts whether patients respond to cancer immunotherapy

Posted: 08 Jul 2022 09:36 AM PDT

Immunotherapies, such as immune checkpoint inhibitors, have transformed the treatment of advanced stage cancers. Unlike chemotherapies that kill cancer cells, these drugs help the body's immune system to find and destroy cancer cells themselves. Unfortunately, only a subset of patients responds long-term to immune checkpoint inhibitors -- and these treatments can come at a high cost and with side effects. Researchers have developed a two-step approach using whole exome sequencing to zero in on genes and pathways that predict whether cancer patients will respond to immunotherapy. The study, published in Nature Communications and conducted by researchers at New York University, Weill Cornell Medicine, and the New York Genome Center, illustrates how the use of whole exome sequencing can better predict treatment response than current laboratory tests.

Many of the species were uncovered as the by-product of ecological research: the species diversity in tropical forests is still so poorly known that field trips and herbarium work keep discovering previously unknown species.

Narwhals show physiological disruption in response to seismic survey ship noise

Posted: 08 Jul 2022 06:56 AM PDT

The reaction of narwhals to the loud noise from seismic air guns used in oil exploration involves a disruption of the normal physiological response to intense exercise as the animals try to escape the noise. The overall effect is a large increase in the energetic cost of diving while a paradoxically reduced heart rate alters the circulation of blood and oxygen.

Genetically-enhanced biocontrols can help fight large invasive mammals, study finds

Posted: 08 Jul 2022 06:56 AM PDT

Genome engineering using CRISPR offers novel solutions for controlling invasive alien species, but its efficiency for eradicating harmful vertebrates is yet to be tested. In a new study, researchers confirm that genetic biocontrols could rapidly eradicate animals like rats, mice and rabbits. Others -- like cats and foxes -- would, however, take a lot longer.

When words fail, gestures can help to get the message across -- especially for people who have a language disorder. An international research team has now shown that listeners attend the gestures of people with aphasia more often and for much longer than previously thought. This has implications for the use of gestures in speech therapy.

Posted: 07 Jul 2022 11:19 AM PDT

Financial incentives play an important role in the widespread adoption of electric vehicles. New research, however, finds that not all financial incentives are created equal in the eyes of prospective car buyers, and the current federal incentive -- a tax credit -- is, in fact, valued the least by car buyers.

Scientists use mini-kidney models to identify potential drugs for polycystic kidney disease

Posted: 07 Jul 2022 11:18 AM PDT

Scientists hsve generated simple kidney-like structures called organoids and used them to identify potential drugs to treat adult-onset polycystic kidney disease. To accelerate the quest for new treatments for ADPKD, researchers used pluripotent stem cells to grow organoids consisting of one or two structures resembling the kidney's filtering units, known as nephrons. To make the organoids useful for studying ADPKD, the scientists used CRISPR/Cas9 gene editing to inactivate PKD1 or PKD2. As anticipated, the gene-edited organoids began to form cysts. After testing a collection of 247 enzyme inhibitor compounds on the organoids, the scientists found nine that inhibited the growth of the cysts, without stunting the overall growth of the organoids. One compound, quinazoline, was particularly effective.

Oceanographers develop new model to better predict barrier island retreat

Posted: 07 Jul 2022 11:18 AM PDT

Barrier islands protect the coastline from storms, storm surge, waves and flooding. They can act as a buffer between the ocean and beachfront property. As sea level rises, barrier islands retreat, or move closer toward the shore, which diminishes the buffer and protection. New information shows the retreat of coastal barrier islands will accelerate by 50 percent within a century, even if sea level continues to rise at its present rate.
