Queen’s University researchers uncover brain-based marker of new thoughts and discover we have more than 6,000 thoughts each day.

Researchers at Queen’s University have established a method that, for the first time, can detect indirectly when one thought ends and another begins. Dr. Jordan Poppenk (Psychology) and his master’s student, Julie Tseng, devised a way to isolate “thought worms,” consisting of consecutive moments when a person is focused on the same idea. This research was recently published in Nature Communications.

“What we call thought worms are adjacent points in a simplified representation of activity patterns in the brain. The brain occupies a different point in this ‘state space’ at every moment. When a person moves onto a new thought, they create a new thought worm that we can detect with our methods,” explains Dr. Poppenk, who is the Canada Research Chair in Cognitive Neuroscience. “We also noticed that thought worms emerge right as new events do when people are watching movies. Drilling into this helped us validate the idea that the appearance of a new thought worm corresponds to a thought transition.”

Scientists successfully edited RNA in a living animal in such a way that the repaired RNA then corrected a mutation in a protein that gives rise to a debilitating neurological disorder in people known as Rett syndrome.

The advance by researchers at Oregon Health & Science University publishes in the journal Cell Reports.

“This is the first example of using programmable RNA editing to repair a gene in mouse models of a neurological disease,” said senior author Gail Mandel, Ph.D., senior scientist in the OHSU Vollum Institute. “This gives us an approach that has some traction.”

A new method developed at Cold Spring Harbor Laboratory (CSHL) uses DNA sequencing to efficiently map long-range connections between different regions of the brain. The approach dramatically reduces the cost of mapping brain-wide connections compared to traditional microscopy-based methods.

Neuroscientists need anatomical maps to understand how information flows from one region of the brain to another. “Charting the cellular connections between different parts of the brain—the connectome—can help reveal how the nervous system processes information, as well as how faulty wiring contributes to mental illness and other disorders,” says Longwen Huang, a postdoctoral researcher in CSHL Professor Anthony Zador’s lab. Creating these maps has been expensive and time-consuming, demanding massive efforts that are out of reach for most research teams.

#HubbleClassic On January 19, 2015, Hubble captured a global map of Jupiter. This video was made from the observations.

Today, Jupiter is at opposition, meaning it shines in our sky all night long and is the closest to Earth that it’ll be all year.

Moderna, Inc.’s COVID-19 vaccine candidate mRNA-1273 will advance to a 30,000-participant Phase III trial later this month, following publication of additional positive Phase I data from a study led by the National Institutes of Health (NIH)’s National Institute of Allergy and Infectious Diseases (NIAID).

Moderna said its closely-watched COVID-19 vaccine candidate mRNA-1273 will advance to a 30,000-participant Phase III trial later this month, following publication of additional positive Phase I data from a study led by the NIH’s National Institute of Allergy and Infectious Diseases (NIAID).

The Phase III “COVE” study (NCT04470427) is expected to begin registration at study centers nationwide beginning on July 21 with study initiation set for six days later. The primary endpoint of the randomized, 1:1 placebo-controlled trial will be the prevention of symptomatic COVID-19 disease. Key secondary endpoints include prevention of severe COVID-19 disease as defined by the need for hospitalization, and prevention of infection by SARS-CoV-2, Moderna said.

The first episode of “Hubble – Eye in the Sky” is here! 🎥

Have you ever wondered how a telescope in space is operated from down on Earth? Welcome to the Hubble control center. Find out how extraordinarily detailed observations are made with an orbiting space telescope, and get a look at Hubble’s on-the-ground replica that engineers and scientists use down here to fix problems up there.
