Technique improves the reasoning capabilities of large language models

CAMBRIDGE, MA - Large language models like those that power ChatGPT have shown impressive performance on tasks like drafting legal briefs, analyzing the sentiment of customer reviews, or translating documents into different languages. These machine-learning models typically use only natural language to process information and answer queries, which can make it difficult for them to perform tasks that require numerical or symbolic reasoning. For instance, a large language model might be able to memorize and recite a list of recent U.S. presidents and their birthdays, but that same model could fail if asked the question “Which U.S. presidents elected after 1950 ...

URI study examines challenges, barriers to care for individuals leaving residential substance use facilities

Residential treatment is among the most effective tools for treating substance use disorder, with people in these settings showing improvement not only in their substance use but also in their mental health, social functioning and quality of life. However, when people leave residential substance use facilities, they face immense challenges as they attempt to reintegrate into their communities and return to their normal lives. As many as 40 to 70 percent of people who complete residential treatment return ...

Some CRISPR screens may be missing cancer drug targets

CRISPR/Cas9 gene editing has made possible a multitude of biomedical experiments including studies that systematically turn off genes in cancer cells to look for ones that the cancer cells heavily depend on to survive and grow. These genes, or “cancer dependencies,” are often promising drug targets. But new research shows that many of these CRISPR screening experiments rely on components, called CRISPR/Cas9 guides, that do not perform equally well in cells from people of all ancestries, which can cause CRISPR screens to miss cancer dependencies. These CRISPR guides are short sequences of RNA that ...

$18.5 million U19 grant will study B and T memory cells in transplanted lungs, uteruses and kidneys

BIRMINGHAM, Ala. – Memory immune cells reside in many tissues, poised to react to a second infection or continuing antigen. Yet little is known about these tissue-resident memory cells — how they get there, how they evolve and how they compete in tissues. A five-year, $18.5 million grant will allow University of Alabama at Birmingham researchers to investigate T and B tissue-resident memory cells, known as TRM and BRM cells, in three unique sites — transplanted lungs, transplanted kidneys and the transplanted ...

St. Jude scientists solve decades long mystery of NLRC5 sensor function in cell death

(MEMPHIS, Tenn. – June 14, 2024) The innate immune system is responsible for protecting the human body from threats that could cause disease or infection. The system relies on innate immune sensors to detect and transmit signals about these threats. One of the key innate immune strategies to respond to threats is through cell death. New research from St. Jude Children’s Research Hospital discovered that NLRC5 plays a previously unknown role as an innate immune sensor, triggering cell death. The findings, published in Cell, show how NLRC5 drives PANoptosis, a prominent type of inflammatory cell death. This understanding has implications for the development of therapeutics ...

Gonadal function in male mice disrupted by prenatal risk factors

Researchers have consistently shown that prenatal exposure to Di (2-ethyhexyl) phthalate harms the reproductive system in male mice and causes fertility defects. In a new study, scientists from the University of Illinois Urbana-Champaign have shown that the combination of DEHP and a high-fat diet in pregnant mice can cause more damage to pups than each factor alone.  Male reproductive disorders are a growing issue due to the global decrease in sperm count and quality. Concerningly, chemicals like DEHP, which can be found in food storage containers, pharmaceuticals, and building materials, have been ...

Endangered sea cucumbers for sale in NYC food markets

ITHACA, N.Y. - After surveying food market retailers in three New York City Chinatown districts, Cornell University researchers have found genetic evidence that some endangered species of sea cucumbers – considered a pricey but nutritious dried delicacy – are being sold to consumers. The researchers collected 103 samples of dried sea cucumbers from retail food shops. By using mitochondrial DNA testing, they successfully identified 74 examples of sea cucumbers. Eight were classified as brown sea cucumbers– which are threatened and found on the International Union for the Conservation of Nature (IUCN) Red List due to overharvesting. “We ...

Novel insights into fluorescent ‘dark states’ illuminate ways forward for improved imaging

(MEMPHIS, Tenn. – June 14, 2024) Scientists at St. Jude Children’s Research Hospital today announced a way to improve molecular scale distance measurements using single-molecule fluorescence resonance energy transfer (smFRET). smFRET quantifies the excitation and emission properties of chemicals called fluorophores.    When an excited electron in the fluorophore relaxes, it emits light after a delay, causing the molecule to glow (fluoresce). However, fluorophores don’t always fluoresce after excitation. Instead, through quantum mechanical ...

AI enables faster, more effective antibiotic treatment of sepsis

Atlanta, GA—Sepsis is a life-threatening infection complication and accounts for 1.7 million hospitalizations and 350,000 deaths annually in the U.S. Fast and accurate diagnosis is critical, as mortality risk increases up to 8% every hour without effective treatment. However, the current diagnostic standard is reliant on culture growth, which typically takes 2-3 days. Doctors may choose to administer broad-spectrum antibiotics until more information is available for an accurate diagnosis, but these can have limited efficacy and potential toxicity to the patient. In a study presented at ASM Microbe, a team from Day Zero Diagnostics unveiled a novel approach to antimicrobial susceptibility ...

Quantum entanglement measures Earth rotation

A team of researchers led by Philip Walther at the University of Vienna carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work, just published in Science Advances, represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity. Optical Sagnac interferometers are the most sensitive devices to rotations. They have been pivotal in our understanding of fundamental physics since the early years of the last century, contributing to establish ...

Ex vivo gene editing and cell therapy for hereditary tyrosinemia type 1

Background: We previously demonstrated the successful use of in vivo CRISPR gene editing to delete 4-hydroxyphenylpyruvate dioxygenase (HPD) to rescue mice deficient in fumarylacetoacetate hydrolase (FAH), a disorder known as hereditary tyrosinemia type 1 (HT1). The aim of this study was to develop an ex vivo gene-editing protocol and apply it as a cell therapy for HT1. Methods: We isolated hepatocytes from wild-type (C57BL/6J) and Fah-/- mice and then used an optimized electroporation protocol to deliver Hpd-targeting CRISPR-Cas9 ribonucleoproteins into hepatocytes. Next, hepatocytes were transiently incubated in ...

Sharks have depleted functional diversity compared to the last 66 million years

New research by Swansea University and the University of Zurich has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million years to its lowest value in the present day. Modern sharks are among the ocean’s most threatened species; yet have notably survived numerous environmental changes in their 250-million-year history. Today, their more than 500 species play many different ecological roles, from apex predators to nutrient transporters. Ecological roles are determined by species’ traits such as body size, ...
