Restoration of distorted images is one of the most interesting and important problems of image processing - from the theoretical, as well as from the practical point of view. There are especial cases: blurring due to incorrect focus and blurring due to movement - and these very defects, which each of you knows very…
A differential diagnosis for the weird and the awkward
Modifying the optical properties of biological tissues with tartrazine
Scholarly research is often about the latest findings - the newest knowledge that our colleagues have gleaned from nature. Some articles bu...
The PCR diagnostic platform Vivalytic enables COVID-19 rapid tests — a blessing for Clemens Weller and his mother, who suffers from dementia. Learn more!
UChicago Pritzker Molecular Engineering Prof. Y. Shirley Meng’s Laboratory for Energy Storage and Conversion has created the world’s first anode-free sodium
Rootclaim helps people understand complex issues by combining the power of crowdsourced information with the mathematical validity of statistics.
Many public address systems emit a continuous near-ultrasonic sound that is used for system health monitoring.
The earth contains a lot of titanium - it’s the ninth most abundant element in the earth’s crust.
The environmental and cognitive factors at play that have people eating more without realising.
A single intravenous dose of Ewingella americana achieved complete tumor elimination in 100% of treated animals, with no detectable toxicity—outperforming chemotherapy and immunotherapy.
The post after this one on “black rust” describes why you should heat the pan before applying oil for seasoning. This helps the seasoning to adhere and makes the pan pleasantly black.
Nine observations about what happens when you eat only potatoes
The Nobel Prize in Physiology or Medicine 2025 was awarded jointly to Mary E. Brunkow, Frederick J. Ramsdell and Shimon Sakaguchi "for their discoveries concerning peripheral immune tolerance"
Comprehensive review brings together global evidence to strengthen public trust and counter misinformation as mRNA vaccines expand to prevent and treat more diseases.
A new study from Boston University is the first to illustrate that the brain’s cerebrospinal fluid pulses during sleep, and that these motions are closely tied with brain wave activity and blood flow. It may confirm the hypothesis that CSF flow and slow-wave activity both help flush toxic, memory-impairing proteins…
Can the current crop of vaccines get us to herd immunity even if variants become widespread? A Harvard immunologist says yes.
Scientists have discovered what they believe to be the central mechanism behind cognitive decline associated with normal aging.
LOS ANGELES — A new drug-releasing system, TAR-200, eliminated tumors in 82% of patients in a phase 2 clinical trial for individuals with high-risk non-muscle-invasive bladder cancer whose cancer had previously resisted treatment. In the majority of cases, the cancer disappeared after only three months of treatment…
Aayush Jain’s dissertation, “Indistinguishability Obfuscation from Well-Studied Assumptions,” established the feasibility of mathematically rigorous software obfuscation from well-studied hardness conjectures. The central goal of software obfuscation is to transform source code to make it unintelligible without…
Average blood levels far exceed those considered to cause impairment.
The world needs ideas and innovation to make progress. Creative and talented people are everywhere, but the opportunity to develop is limited to only a small number of well-off children. The world loses out as a result.
I wrote a little book about entropy; here’s the current draft: • What is Entropy? If you see typos and other mistakes, or have trouble understanding things, please let me know! An altern…
The Nobel Prize in Physics 2020 was divided, one half awarded to Roger Penrose "for the discovery that black hole formation is a robust prediction of the general theory of relativity", the other half jointly to Reinhard Genzel and Andrea Ghez "for the discovery of a supermassive compact object at the centre of our…
A new solar desalination system takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren’t needed often, meaning the system could potentially produce drinking water that is cheaper than tap water.
