The behavior of 20 mice on the International Space Station is helping shed some light on how humans might adapt to living in space.

The female mice were flown out on the International Space Station aboard an uncrewed SpaceX Dragon capsule and spent up to 37 days floating in NASA’s Rodent Habitat. Video footage show that the mice immediately began their usual grooming, feeding, huddling and socializing, but within 10 days of leaving Earth, younger mice began to run in circles around their cage.

A part of growing up is becoming aware of changes. Have you ever wondered how your neighborhood completely changes when you are walking down those familiar streets ten to fifteen years later? Now, imagine if you lived in a place surrounded with trees and found all of them have vanished when you returned from a trip? That is what happens when we have rampant deforestation taking place all over the world. We are aware of the problem, but few countries are taking any step towards it. That’s why we need to step up as individuals and make a change.

Cell-by-cell genetic analyses of developing brain tissues in neonatal mice and laboratory models of brain cancer allowed scientists to discover a molecular driver of the highly aggressive, deadly, and treatment-resistant brain cancer, glioblastoma.

Published findings in Cell Stem Cell describe how the single-cell analyses identified a subpopulation of cells critical to glioblastoma formation—the early primitive progenitor cells of oligodendrocyte brain cells, pri-OPC progenitors, according to Q. Richard Lu, Ph.D., lead investigator and Scientific Director of the Brain Tumor Center at Cincinnati Children’s Hospital Medical Center.

The data suggest that reprogramming of primitive oligodendrocyte progenitors into a stem-like state plays an important role in glioma initiation and progression. The researchers’ primary molecular target in the study, a protein called Zfp36l1, launches biological programs that mirror those of healthy early brain development in the mice, but instead help fuel brain cancer growth. The discovery presents an opportunity to find out if new therapeutic approaches can stop glioblastoma at its earliest stages of initial formation or recurrence, Lu said.

MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) is developing a robot that sorts for recycling. Fundamentally, the squad’s robot arm has soft grippers ad the robot can take objects from a conveyor belt and identify what they are made from— by touch.

Tactile sensors on the robot are the main feature. The sensorized gripper is fully electrical driven. It can detect the difference between paper, metal and plastic.

In fact, according to IRENA’s new report, the most cost-effective strategy to achieve a “climate-safe future” — keeping global warming below 2 degrees Celsius (3.6 degrees Fahrenheit) — is an accelerated energy transition to renewables and energy efficiency coupled with electrification of key sectors like transportation.

This Renewable Energy Roadmap (REmap) scenario “would also save the global economy up to USD 160 trillion cumulatively over the next 30 years in avoided health costs, energy subsidies and climate damages.”

At the same time, IRENA reports, “every dollar spent on energy transition would pay off up to seven times.”

Researchers have identified ketamine-induced brain-related changes that are responsible for maintaining the remission of behaviors related to depression in mice—findings that may help researchers develop interventions that promote lasting remission of depression in humans. The study, funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, appears in the journal Science.

Major depression is one of the most common mental disorders in the United States, with approximately 17.3 million adults experienced a major depressive episode in 2017. However, many of the neural changes underlying the transitions between active depression, remission, and depression re-occurrence remain unknown. Ketamine, a fast-acting antidepressant which relieves depressive symptoms in hours instead of weeks or longer, provides an opportunity for researchers to investigate the short- and long-term biological changes underlying these transitions.

“Ketamine is a potentially transformative treatment for depression, but one of the major challenges associated with this drug is sustaining recovery after the initial treatment,” said study author Conor Liston, M.D., Ph.D., of Weill Cornell Medicine, New York City.

The ions at its core will be seven times hotter than those of the real Sun.

In quantum physics, a vacuum is not empty, but rather steeped in tiny fluctuations of the electromagnetic field. Until recently it was impossible to study those vacuum fluctuations directly. Researchers at ETH Zurich have developed a method that allows them to characterize the fluctuations in detail.

Emptiness is not really empty – not according to the laws of quantum physics, at any rate. The vacuum, in which classically there is supposed to be “nothing,” teems with so-called vacuum fluctuations according to quantum mechanics. Those are small excursions of an electromagnetic field, for instance, that average out to zero over time but can deviate from it for a brief moment. Jérôme Faist, professor at the Institute for Quantum Electronics at ETH in Zurich, and his collaborators have now succeeded in characterizing those vacuum fluctuations directly for the first time.

“The vacuum fluctuations of the electromagnetic field have clearly visible consequences, and among other things, are responsible for the fact that an atom can spontaneously emit light,” explains Ileana-Cristina Benea-Chelmus, a recently graduated Ph.D. student in Faists laboratory and first author of the study recently published in the scientific journal Nature. “To measure them directly, however, seems impossible at first sight. Traditional detectors for light such as photodiodes are based on the principle that light particles – and hence energy – are absorbed by the detector. However, from the vacuum, which represents the lowest energy state of a physical system, no further energy can be extracted.”
