Hallucinogen use other than LSD on the rise among young adults
Study: Hallucinogen use among young adults ages 19-30 in the United States: Changes from 2018 to 2021 Young adults ages 19 to 30 nearly doubled their past 12-month use of non-LSD hallucinogens in the United States from 2018 to 2021, according to a study by the University of Michigan and Columbia University.

Health insurance coverage rises for LGBT adults yet access lags, per study
LGBT adults remain significantly more likely than others to report going without health care because of cost despite closing gaps in the coverage itself, according to researchers at the University of Michigan, Harvard University and Massachusetts Institute of Technology. Those disparities in access to care have persisted despite the potential for improvements envisioned by the Affordable Care Act (ACA) insurance coverage expansions and the 2015 Supreme Court ruling on marriage equality.

Researchers make language models scalable self-learners
The scientists used a natural language-based logical inference dataset to create smaller language models that outperformed much larger counterparts. Socrates once said: "It is not the size of a thing, but the quality that truly matters.

New model offers a way to speed up drug discovery
By applying a language model to protein-drug interactions, researchers can quickly screen large libraries of potential drug compounds. Huge libraries of drug compounds may hold potential treatments for a variety of diseases, such as cancer or heart disease. Ideally, scientists would like to experimentally test each of these compounds against all possible targets, but doing that kind of screen is prohibitively time-consuming.

Observations by NASA's NuSTAR X-ray telescope give astronomers new clues about the brightest and most energetic gamma-ray burst ever detected. When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Most gamma-ray bursts occur when the core of a star more massive than our Sun collapses, becoming a black hole.
Electronic health records can contain bias, potentially impacting clinical trials
Results of clinical trials are only as good as the data upon which they rest. This is especially true in terms of diversity - if most people in a trial are from a certain race or socioeconomic group, then the results may not be broadly applicable. This form of potential bias is not a novel concept.

Black men are the most frequent victims of killings by off-duty officers
A new study assessed off-duty police-perpetrated violence, finding it often affected officers- own social networks and Black men were the most frequent victims. Black men are the most common victims of killings committed by off-duty police officers in the U.S., according to a new Yale-led study. In an analysis of 242 incidences in which people were killed by police officers when they were off duty between 2013 and 2021, a research team found that nearly 40% of the victims were Black men.

Machine learning helps scientists see how the brain adapts to different environments Visualizing connections between nerve cells in the brain could yield insights into how our brains change with learning, aging, injury, and disease Johns Hopkins scientists have developed a method involving artificial intelligence to visualize and track changes in the strength of synapses-the connection points through which nerve cells in the brain communicate-in live animals.
The impact of artificial intelligence in communication, the subject of a special edition of UPF’s journal Hipertext.net
In this special issue, some fifteen experts on communication and digital technologies from universities from around the world analyse the impact of artificial intelligence in areas of communication such as the generation of texts, images, videos and sound and the concept of copyright. During recent months, the social debate around the implications of artificial intelligence (AI) have intensified in many areas, such as the generation of texts and images or of audiovisual content.

A compound from fruit flies could lead to new antibiotics
Scientists at the University of Illinois Chicago have found that a peptide from fruit flies could lead to new antibiotics. Their research, which is published in Nature Chemical Biology, shows that the natural peptide, called drosocin, protects the insect from bacterial infections by binding to ribosomes in bacteria.

Finding clues about the process of cell plasticity
Study: ROS signaling-induced mitochondrial Sgk1 expression regulates epithelial cell renewal Researchers have long thought that once a cell starts down its path of differentiation, growing into a skin cell or a liver cell or a neuron, that path could not be changed. But over the past two decades, scientists have realized this pathway is more complex.

Nanobiotics: AI for discovering where and how nanoparticles bind with proteins
A new tool in the fight against superbugs goes beyond protein folding simulations like AlphaFold, potentially revealing antibiotic candidates Identifying whether and how a nanoparticle and protein will bind with one another is an important step toward being able to design antibiotics and antivirals on demand, and a computer model developed at the University of Michigan can do it.

Women’s gymnastics leads NCAA sports with most preseason concussions
Study: Under-representation of female athletes in research informing influential concussion consensus and position statements: an evidence review and synthesis Women's gymnastics has the highest rate of preseason concussion of all NCAA sports, with women gymnasts experiencing concussions at a rate 50% higher than football players.

New observations and excavations in South African caves have found that Homo naledi , an early human ancestor, intentionally buried their dead and made crosshatch engravings in the cave walls nearby. Fossils of Homo naledi were first discovered in these caves 10 years ago by a team of researchers led by paleoanthropologist Lee Berger , now a National Geographic Explorer in Residence, with key participation by John Hawks of the University of Wisconsin-Madison and other UW-Madison researchers.
Benefits of later school entry for kids spill over to younger siblings
A Yale-led study shows that having an older sibling who succeeds at school helps children, especially from disadvantaged families, perform well academically. Having a high-achieving older sibling helps children, especially those from socioeconomically disadvantaged families, succeed academically, according to a new Yale-led study.

U-M expert shares thoughts on next steps after US report on social media’s effects on youth
A University of Michigan public policy expert who has reviewed the U.S. surgeon general's advisory outlining social media's profound risks to children's mental health says policymakers will need a great deal more data before making any formal recommendations. That research, she adds, should involve those most affected by the technology-and those responsible for it should be working on effective solutions.

Scaling audio-visual learning without labels
A new multimodal technique blends major self-supervised learning methods to learn more similarly to humans. Researchers from MIT, the MIT-IBM Watson AI Lab, IBM Research, and elsewhere have developed a new technique for analyzing unlabeled audio and visual data that could improve the performance of machine-learning models used in applications like speech recognition and object detection.

40 Hz vibrations reduce Alzheimer’s pathology, symptoms in mouse models
Tactile stimulation improved motor performance, reduced phosphorylated tau, preserved neurons and synapses, and reduced DNA damage, a new study shows. Evidence that noninvasive sensory stimulation of 40 Hz gamma frequency brain rhythms can reduce Alzheimer's disease pathology and symptoms, already shown with light and sound by multiple research groups in mice and humans, now extends to tactile stimulation.

An unprecedented dataset containing the genetic information of 233 species promises to improve our understanding of primates- evolutionary biology. A new dataset of genetic information collected from 233 primate species, the largest and most complete of its kind, promises to yield insights into primates- evolutionary biology and how genetics influences their behavior, says Yale biological anthropologist Eduardo Fernandez-Duque.
