Gender diversity and brain morphology among adolescents

JAMA Network Open

2023-05-12

(Press-News.org) About The Study: The findings of this study of 2,165 adolescents from the Netherlands general population suggest that global brain volumetric measures did not differ between adolescents who reported gender diversity and those who did not. However, these findings further suggest that gender diversity in the general population correlates with specific brain morphologic features in the inferior temporal gyrus among youths who are assigned male at birth. Replication of these findings is necessary to elucidate the potential neurobiological basis of gender diversity in the general population.

Association of hospital adoption of probiotics with outcomes among neonates with very low birth weight

2023-05-12

About The Study: In this study of 307,000 neonates with very low birth weight, adoption of routine use of probiotics in neonatal intensive care units increased slowly from 2012 to 2019 and was associated with lower necrotizing enterocolitis risk but not with sepsis or mortality rates.

A look inside stem cells helps create personalized regenerative medicine

2023-05-12

Organelles – the bits and pieces of RNA and protein within a cell – play important roles in human health and disease, such as maintaining homeostasis, regulating growth and aging, and generating energy. Organelle diversity in cells not only exists between cell types but also individual cells. Studying these differences helps researchers better understand cell function, leading to improved therapeutics to treat various diseases. In two papers out of the lab of Ahmet F. Coskun, a Bernie Marcus Early Career professor in the Coulter Department of Biomedical Engineering at the Georgia Institute of Technology and Emory University, researchers examined a specific ...

The beginning is the end

2023-05-12

All cells in an organism contain identical DNA sequence. What determines the identity and function of individual cells and tissues, is the set of genes that will be active in a given place, at a given time. These active genes are transcribed from the DNA template into distinct messenger RNA (mRNA) molecules and will encode the proteins the cell needs to function. At specific places called promoters, a complex molecular machinery starts transcribing DNA sequences into mRNA. Interestingly, most genes contain multiple possible sites where transcription ...

New artificial intelligence algorithm for more accurate plant disease detection

2023-05-12

Every year, plant diseases caused by bacteria, viruses, and fungi contribute to major economic losses. The prompt detection of these diseases is necessary to curb their spread and mitigate agricultural damage, but represents a major challenge, especially in areas of high-scale production. Smart agriculture systems use camera surveillance equipped with artificial intelligence (AI) models to detect features of plant diseases, which often manifest as changes in leaf morphology and appearance. However, conventional methods ...

Visualizing PET's degradation by bacterial enzymes

2023-05-12

The rigidity, transparency and hardness of PET (Polyethylene Terephthalate) make it one of the most valuable plastics for the manufacture of plastic bottles, packaging and other single-use products. However, these characteristics make it highly persistent in the environment, to the point that a plastic PET bottle may take several hundred years to degrade in the ocean. At the molecular level, PET, and all plastics, have a polymeric structure made up of tens of thousands of repetitions of small subunits called monomers. In the last decades, the degradation ...

Study highlights best practices in buffelgrass control

2023-05-12

WESTMINSTER, Colorado – 9 May, 2023 – Buffelgrass is a highly invasive perennial found in arid regions around the globe. It is known to reduce the biodiversity of native ecosystems and to increase the frequency and intensity of wildfires. A team of researchers recently took a close look at efforts to control buffelgrass in Arizona’s Saguaro National Park, located in the Sonoran Desert. An article featured in volume 16, issue 1 of the journal Invasive Plant Science and Management describes what that investigation can tell us about effective control strategies. ...

Scientists discover a deadly brain cancer’s hidden weakness

2023-05-12

The difficult-to-treat brain cancer glioblastoma steals a person’s mental faculties as it spreads, yet the tumor’s insidious ability to infiltrate neighboring networks in the brain could also prove its undoing. Scientists at UC San Francisco have discovered that neural activity in these deadly tumors can restructure connections in surrounding brain tissue, causing the cognitive decline associated with the disease, and that the drug gabapentin, commonly used to prevent seizures, could block this growth-causing ...

Researchers discover a way to improve nonviral gene editing as well as a new type of DNA repair

2023-05-12

(Santa Barbara, Calif.) — Gene editing is a powerful method for both research and therapy. Since the advent of the Nobel Prize-winning CRISPR/Cas9 technology, a quick and accurate tool for genome editing discovered in 2012, scientists have been working to explore its capabilities and boost its performance. Researchers in UC Santa Barbara biologist Chris Richardson’s lab have added to that growing toolbox, with a method that increases the efficiency of CRISPR/Cas9 editing without the use of viral material to deliver the genetic template used to edit the target genetic sequence. According to their new paper ...

Vast majority of tweets about obesity are negative, study finds

2023-05-12

**Note: the release below is a special early release from the European Congress on Obesity (ECO, Dublin, 17-20 May). Please credit the conference if you use this story** New research to be presented at next week’s European Congress on Obesity (ECO) in Dublin, Ireland (17-20 May), has found that tweets about obesity are predominantly negative. The analysis, by researchers in Switzerland and the UK, also found that Twitter activity spiked around the time of significant political events. These included comments about Donald Trump’s weight when he was US president and ...

USC research identifies biomarker that may predict treatment response to chemoimmunotherapy

2023-05-12

Cutting-edge cancer treatments like immunotherapy are offering new hope for patients, often in combination with more common approaches such as chemotherapy. But determining the best treatment combination isn't always straightforward. Many patients spend valuable time on expensive therapies with serious side effects that aren’t effective against their cancer. Now, a new discovery is poised to help. Researchers from USC Norris Comprehensive Cancer Center have identified a biomarker that indicates which patients with non-small cell lung cancer (NSCLC) will respond well to chemoimmunotherapy. The biomarker, ...
