Is there a connection between cannabis use and binge eating? This is what a recent study published in Experimental and Clinical Psychopharmacology hopes to address as a team of researchers investigated the medical risks associated with cannabis use and binge eating, specifically the link between the two. This research marks only the third study conducted to make a connection between cannabis use and binge eating disorder and holds the potential for scientists, medical practitioners, and patients make better informed clinical decisions for treating binge eating.

“Distinguishing the relationship between cannabis use, eating disorder severity and other psychiatric symptoms in binge eating patients is necessary for informing screening and clinical recommendations,” said Megan Wilkinson, who is a PhD student in Drexel University’s College of Arts and Sciences and lead author of the study.

For the study, the researchers enlisted 165 participants who were pursuing medical treatment for binge eating and were asked to report both their cannabis and alcohol use as part of the survey. In the end, the researchers found that 23 percent of the participants had used cannabis within the prior three months. Additionally, the participants were also found to have increased alcohol consumption, as well. In terms of the connection between cannabis use and binge eating, while the researcher concluded that cannabis use did not result in increased binge eating, they found the opposite in that binge eating could result in increased cannabis use, as noted by the 23 percent participants who reported using cannabis.

A head injury serious enough to affect brain function, such as that caused by a car accident or sudden fall, leads to changes in the brain beyond the site of impact, Tufts University School of Medicine scientists report in the journal Cerebral Cortex. In an animal model of traumatic brain injury, the researchers found that both hemispheres work together to forge new neural pathways in an attempt to replicate those that were lost.

“Even areas far away from the injury behaved differently immediately afterward,” says first author Samantha Bottom-Tanzer, an MD/Ph. D. student in neuroscience at the School of Medicine. “Traumatic brain injury research tends to focus on the region of injury, but this study makes a good case that the entire brain can be affected, and imaging in distal regions can provide valuable information.”

Bottom-Tanzer and colleagues are the first to use an imaging technique combining fluorescent sensors of neuronal activity and electrodes to record how many parts of the brain talk to each other after a brain injury. The team tracked neural activity in mice for up to three weeks post-injury during periods of exercise and rest.

A U.S. company’s 14-foot-tall spacecraft began speeding to the moon, where the vehicle is expected to try to make history by pulling off the first-ever commercial lunar landing.

The lander, called Odysseus and developed by Houston-based Intuitive Machines, isn’t carrying crew, but rather is ferrying scientific and commercial payloads. It was launched at 1:05 a.m. ET Thursday from NASA’s Kennedy Space Center in Florida on a SpaceX rocket and later separated from the upper part of that vehicle to start a roughly 239,000-mile journey, according to a livestream.

The spacecraft had a successful launch and connected to radio communications with the company’s mission operations center in Houston, Intuitive Machines said.

SpaceX has launched a mission to the moon that will make history if it achieves a successful landing on the lunar surface week.

No American spacecraft has made a soft landing on the Moon since NASA’s Apollo 17 in 1972, but that could change soon as the Intuitive Machines’ Nova-C lander launched from the historic Launch Complex 39A at NASA’s Kennedy Space Center at 1:05 am EST (10:05 pm PST) last night. With a currently scheduled landing date of February 22, Nova-C (also called IM-1 Odysseus) is slated to land in Malapert-A crater, which is approximately 190 miles (300 kilometers) from the Moon’s south pole. This landing will also mark the first time a private company will perform a soft landing on the Moon and holds the potential to test technologies that could be used on future human missions with NASA’s Artemis program.

“NASA scientific instruments are on their way to the Moon – a giant leap for humanity as we prepare to return to the lunar surface for the first time in more than half a century,” NASA Administrator Bill Nelson said in a statement. “These daring Moon deliveries will not only conduct new science at the Moon, but they are supporting a growing commercial space economy while showing the strength of American technology and innovation. We have so much to learn through CLPS flights that will help us shape the future of human exploration for the Artemis Generation.”

The science instruments that will be traveling with Nova-C include the Lunar Node 1 Navigation Demonstrator, Laser Retroreflector Array, Navigation Doppler Lidar for Precise Velocity and Range Sensing, Radio Frequency Mass Gauge, Radio-wave Observations at the Lunar Surface of the Photoelectron Sheath, and Stereo Cameras for Lunar Plume-Surface Studies. All these instruments are designed to investigate how spacecraft can both land and operate on the lunar surface, specifically near the south pole of the Moon.

Previous research has suggested that false-positive mammogram results are associated with higher risk for subsequently developing breast cancer. To further examine this issue, researchers in Sweden used national mammography data to follow 500,000 women (median age, 52) during 30 years (1991–2020). About 45,000 women had false-positive results (i.e., they were recalled for further evaluation but didn’t receive diagnoses of breast cancer at that time). Women with false-positive results were matched with controls to compare rates of subsequent breast cancer diagnosis.

The results include:

Our understanding of how galaxies form and the nature of dark matter could be completely upended after new observations of a stellar population bigger than the Milky Way from more than 11 billion years ago that should not exist.

A paper published today in Nature details findings using new data from the James Webb Space Telescope (JWST). The results find that a massive galaxy in the early universe —observed 11.5 billion years ago (a cosmic redshift of 3.2)—has an extremely old population of stars formed much earlier—1.5 billion years earlier in time (a redshift of around 11). The observation upends current modeling, as not enough dark matter has built up in sufficient concentrations to seed their formation.

Swinburne University of Technology’s Distinguished Professor Karl Glazebrook led the study and the international team, who used the JWST for spectroscopic observations of this massive quiescent galaxy.
