Order AI, a health-tech company operating in Boston, US, has released its new AI app to facilitate healthier dining choices when ordering in or eating out at restaurants. “Unlike traditional diet or tracking apps, Menu – Order AI focuses on real-world decision-making,” details the company. The AI engine scans restaurant and delivery menus in real time to determine which options align best with users’ health goals, from high-protein preferences to diets that are GLP-1 friendly, low-carbohydrate, or low in Weight Watchers points.The app provides personalized meal suggestions within seconds, helping users make “confident, health-aligned decisions without restriction or confusion.”“Our mission…
The black mamba is one Africa’s most deadly venomous snakes.Credit: Matthijs Kuijpers/AlamyAn antivenom using antibodies from a llama and an alpaca can neutralize venom from some of the world’s most venomous snakes, according to a study published today in Nature1. When administered to mice, the treatment conferred protection against toxins from 17 African snake species and reduced skin damage caused by venoms.Snakebites are a neglected public-health issue that is estimated to kill roughly 20,000 people in sub-Saharan Africa every year. Around 300,000 snakebites occur annually in this region, and tissue death from venom leads to approximately 10,000 amputations.Current antivenom treatments…
New research in mice from scientists at New York University Langone Health (NYU Langone Health) and their colleagues elsewhere identifies brain circuits that make memories more stable during learning. The study, which was published in Science, shows that activity in signaling pathways connecting two brain regions, the entorhinal cortex and the CA3 region of the hippocampus, helps mice form stable neural maps of places. The paper, which details the work, is titled “Cortical glutamatergic and GABAergic inputs support learning-driven hippocampal stability.” It builds on data from previous studies that demonstrated the importance of the entorhinal/hippocampal circuit for memory formation and…
Scientists traced how social interaction activates the neurons in the brain to reduce stress signaling and tumor growth, paving the way for brain-targeted treatments that could work in parallel with other cancer therapies.Image credit:©iStock, Fly View ProductionsIn the 1970s and ‘80s, scientists began noticing that people who had few or poor social relationships had a higher risk of developing illnesses and all-cause mortality.1,2 A slew of follow-up studies suggested that social support could protect people from pathological conditions like arthritis, alcoholism, depression, and even death. This link holds true for cancer as well. Upon analyzing disease progression and survival rates…

Thousands of patients with undiagnosed hepatitis B, hepatitis C, or HIV have been identified through a testing programme for bloodborne viruses run in hospital emergency departments.The programme was launched in April 2022 and now covers 34 emergency departments in areas in England with the highest HIV prevalence.1 Blood tests taken during emergency care are automatically tested for HIV, hepatitis B, and hepatitis C unless patients choose to opt out.A new evaluation report2 commissioned by NHS England shows that over 33 months more than 7 million tests for bloodborne viruses were conducted at the 34 sites, with a …

Genomic Proximity Mapping (GPM) captures 3D chromatin interactions, enabling concealed, disease-causing structural variants to be detected in a way not possible through conventional means. The high-throughput chromosome conformation capture sequencing (HiC) method, outlined in The Journal of Molecular Diagnostics, provides a sequence-efficient approach for detecting large-scale chromosomal rearrangements. Unlike traditional linear approaches that treat DNA as a one-dimensional sequence, the Hi-C mapping tool reveals the spatial arrangement…

“Straining really hard during a bowel movement can activate the vagus [nerve],” says Ellen M. Stein, MD, associate professor of medicine in the division of gastroenterology and hepatology at Rutgers Medical School in New Brunswick, New Jersey.The vagus nerve is one of the main nerves in your parasympathetic nervous system, which controls functions like digestion, heart rate, and immune system function.[1] For some people, vagus nerve activation can slow heart rate and lower blood pressure, leading to something called vasovagal syncope, which can cause sudden lightheadedness and fatigue, says Dr. Stein.[2]“If you’re straining or pushing hard, your stomach muscles are…
