These scientists used CRISPR to put an alligator gene into catfish

Posted by in category: biotech/medical

These scientists seem to be enjoying themselves. đŸ€Ł

They just want stronger more disease free fish.


The resulting fish appear to be more resistant to disease and could improve commercial production—should they ever be approved.

Determinants of escapism in adult video gamers with autism spectrum conditions: The role of affect, autistic burnout, and gaming motivation

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

😉


Persons with autism spectrum conditions (ASC) often engage in video gaming, one of the most common leisure activity in this population. Escapism, aimed at the avoidance of negative experiences or self-development, is considered as one of the main gaming motivations. Furthermore, escapism is a self-regulatory strategy used while suffering from autistic burnout, consisting of exhaustion, reduced social skills, anhedonia, and withdrawal. The goal of the current study was to determine predictors of escapism in video gaming among adult gamers with ASC. It was hypothesized that two types of escapism – self-suppression and self-expansion – would differentiate gaming motivations, affective outcomes, anhedonia, and autistic burnout rates. A total of 189 persons participated in the study (Mage = 27.52, SDage = 7.25), including 105 females. The results obtained indicated that self-suppression escapism was predicted by introjected regulation, positive and negative affect, and hedonic tone (F = 8.760, p < .001), while self-expansion was predicted by identified and integrated gaming motivations, hedonic tone, and positive affect (F = 23.066, p < .001). PLS-SEM analysis revealed good fit of the model with autistic burnout predicting self-suppression escapism. These results acknowledge the two-dimensional approach to escapism and highlight potential risk factors of self-suppression, especially among persons presenting symptoms of autistic burnout. Future research and clinical application directions are outlined.

Study uncovers a surprising level of heterogeneity in psychopathy among condemned capital murderers

Posted by in category: biotech/medical

New research sheds light on the psychological profiles of individuals who have been convicted of capital murder in California and sentenced to death. The study, published in the Journal of Forensic Sciences, found a “pronounced heterogeneity” concerning clinical psychopathy. While a substantial proportion of the offenders exhibited heightened psychopathic features, others showed no signs of psychopathy.

Psychopathy is considered important to understanding criminal behavior because it is a personality disorder characterized by a lack of empathy and remorse, along with impulsive and reckless behavior. Research has shown that individuals with psychopathic traits are overrepresented among offenders, particularly those who have committed violent or repeat offenses.

Understanding the characteristics and behaviors associated with psychopathy can aid in the prediction and prevention of criminal behavior, as well as the development of more effective treatment and rehabilitation programs for offenders.

Scientists find drug that can increase life span

Posted by in categories: biotech/medical, life extension

In a study from the University of Auckland, scientists found a drug that can increase life span. The age-old quest for immortality has taken a step forward. The team that long-term treatment of healthy mice from middle age (one year) with a drug currently used to treat cancer can increase their lifespan by an average of 10% to around three years.

How a Brain Molecule Could Halt Multiple Sclerosis

Posted by in categories: biotech/medical, neuroscience

Summary: Injecting the brain molecule into mouse models of multiple sclerosis increased the number of oligodendrocytes. The findings suggest fractalkine may help to slow the progression, or potentially halt multiple sclerosis.

A University of Alberta researcher is one step closer to demonstrating the potential of a brain molecule called fractalkine to halt and even reverse the effects of multiple sclerosis and other neurodegenerative diseases.

Starling Medical’s new urine-testing device turns your toilet into a health tracker

Posted by in categories: biotech/medical, health

If you enjoy some good toilet technology, then I think “urine” for a treat. Starling Medical is poised to launch its at-home urine diagnostic patient-monitoring platform, dubbed “StarStream,” that doesn’t rely on the traditional catching containers or dipsticks.

Now, if you’re thinking this technology sounds familiar, you would be correct: My colleague Haje Jan Kamps wrote about Withings’ U-Scan, a urinalysis device, earlier this month when the health-focused consumer tech company debuted it at CES. U-Scan also sits in the toilet for at-home monitoring.

However, Alex Arevalos, Starling’s co-founder and CEO, told TechCrunch that this is an underserved market — the global urinalysis market is forecasted to be valued at $4.9 billion by 2026, meaning there is plenty of room for Withings and a scrappy startup.

These record-breaking twins were born from 30-year-old frozen embryos. Their mom is only 3 years older than that

Posted by in category: biotech/medical

Three of them were transferred, and two developed. Rachel, who said she had a relatively straightforward pregnancy, gave birth on October 31 at 37 weeks and two days.

Timothy weighed 6 pounds and 7 ounces. Lydia weighed 5 pounds and 11 ounces.

The twins’ record-breaking delivery was verified by the University of Tennessee’s Preston Medical Library. The previous record holder was a child named Molly Gibson, who was born in 2017. The frozen embryo that later became Molly had been stored for 24 years.
