The First Open Source Multilingual Language Model Red-teamed according to the U.S. Executive Order https://huggingface.co/papers/2404.
Pretrained language models underpin several AI applications, but their high computational cost for training limits accessibility.
By contrast, information on coronary inflammation can provide crucial early warning signs of a cardiac event. Yet traditional diagnostic methods of measuring inflammation are not specific for cardiovascular diseases. Inflammation is invisible to CT scans, for instance. And biomarkers such as hsCRP (High-sensitivity C-reactive Protein) measure systemic inflammation, rather than cardiovascular inflammation, so the test may show up high in the case of inflammation driven by non-heart organs.
CaRi-Heart leverages AI tech to detect and quantify coronary inflammation, giving it an edge over traditional diagnostic methods. Cheng explains that while it is important to find patients who already have significantly narrowed coronary arteries, and obviously need immediate treatment, cardiologists often end up archiving many cases of patients with no visible signs of disease but who potentially have high coronary inflammation. This inflammation, driven by cholesterol, or smoking, or diabetes and other risk factors, ultimately causes the wall of the artery to become thickened and narrowed.
Caristo’s CaRi-Heart technology is a non-invasive cloud-based solution that utilizes AI to analyse CT scans, overcoming the limitations of traditional diagnostic methods, offering a more sensitive and specific approach to detecting and quantifying coronary inflammation, says Cheng. CaRi-Heart is the only commercially available technology that can detect and measure coronary inflammation on routine cardiac CT scans, and it has been cleared for clinical use in the UK, EU and Australia.
Professor Jürgen Götz and Dr Pranesh Padmanabhan from the Queensland Brain Institute comment on the successful human trial by the WVU Rockefeller Neuroscience Institute which found a five-fold reduction of amyloid-β in Alzheimer’s patients.
The latest trial results underscore the safety of using…

After three years of collecting scores of data on hundreds of stars, the ULLYSES (Ultraviolet Legacy Library of Young Stars as Essential Standards) survey conducted by NASA’s Hubble Space Telescope officially ended in December 2023, culminating in 220 total stars examined during the survey on data regarding their size, distance from Earth, temperature, chemical characteristics, and rotational speed. Additionally, ULYYSES also contains another 275 stars from the Hubble archive, providing researchers with several decades of new stellar data and holds the potential to help astronomers gain new insights into stellar formation and evolution throughout the universe.

“I believe the ULLYSES project will be transformative, impacting overall astrophysics – from exoplanets, to the effects of massive stars on galaxy evolution, to understanding the earliest stages of the evolving universe,” said Dr. Julia Roman-Duval, who is Implementation Team Lead for ULLYSES and an Associate Astronomer at the Space Telescope Science Institute (STScI). “Aside from the specific goals of the program, the stellar data can also be used in fields of astrophysics in ways we can’t yet imagine.”

The world’s first supercomputer capable of simulating networks at the scale of the human brain has been announced by researchers at the International Centre for Neuromorphic Systems (ICNS) at Western Sydney University.
DeepSouth uses a neuromorphic system which mimics biological processes, using hardware to efficiently emulate large networks of spiking neurons at 228 trillion synaptic operations per second — rivalling the estimated rate of operations in the human brain.
While during Apollo 13 the phrase “Failure is Not an Option” was coined, in life and especially for students, failure must be an option for growth. In this talk, Michelle Lucas encourages failing forward. Michelle Lucas was raised in the Chicagoland area and found a passion for space very early in her life. She studied Aerospace Engineering, Communications & Space Studies at Purdue University and Embry Riddle Aeronautical University. During this time she conducted microgravity fluids research on NASA’s KC-135 aircraft and also worked as a counselor at Space Camp in Florida. After graduation from college, Michelle spent 11 years working at NASA’s Johnson Space Center. She began on the Safety Reliability & Quality Assurance Contract as part of the Payload Safety Review Panel for experiments flying to the International Space Station. After this she worked as a Flight Controller in Mission Control for the International Space Station for the Ops Plan Group and as a Astronaut Technical Instructor in the Daily Operations Group. Additionally she worked with each of the International Partners (European Space Agency – ESA, Japanese Space Agency – JAXA and the Russian Space Agency) in the field of Daily Operations, Flight Controller and Instructor Training. Michelle was responsible for the basic instructional training of all technical instructors for in the US as well as for the ISS International Partners. Michelle was part of the Core NASA Extreme Environment Mission Operations (NEEMO) team for 9 missions where astronauts would carry out analog space missions underwater in the Aquarius habitat. Along the way, Michelle found she has a passion for exciting the next generation and founded the non-profit Higher Orbits to use space to excite and inspire students about STEM, STEAM, Leadership, Teambuilding and Communication. Higher Orbits flagship program is called Go For Launch! This program allows students work with an astronaut and other accomplished individuals in the fields of Space, STEM and STEAM. Additionally, Michelle and a business partner run uniphi space agency – a talent management company for retired astronauts. Michelle is proud to be a Space Camp Alumni and member of the Space Camp Hall of Fame and believes that collaboration in space and STEM is the key to the stars! Space Inspires! This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
A new approach to monitoring arachnid behavior could help understand their social dynamics, as well as their habitat’s health.
Cancer cells release a significantly more concentrated level of acid than previously known, forming an “acid wall” that could deter immune cells from attacking tumors, UT Southwestern Medical Center scientists show in a new study.
Paralysed patients can regain movement and a sense of feeling after being injected with stem cells grown from their own fat, scientists have found.
The research into new experimental therapy has shown that patients who had suffered devastating injuries after car accidents and falls showed a number of improvements.
The treatment involves taking fat from the abdomen or thigh and removing the mesenchymal stem cells – a special type of stem cell that can hone in on injuries, and encourage repair and regeneration.
