Astronomers have discovered a rare binary star system with an orbital period of just 51 minutes – a blazing new record.
In a recent study published in the eLife journal, researchers demonstrated that tumor cells evade immunotherapy by generating unique transient cell-in-cell structures, resistant to chemotherapy and destruction by T cells.
Despite some remarkable success stories, cancer immunotherapies that use the body’s immune system to combat cancer stops working in many patients. It is unclear why this occurs, but how the immune system attacks cancer cells might have a role to play in this phenomenon.
Immunotherapies activate specialized killer T-cells, which trigger the immune response to tumors. These cells can identify cancer cells and inject toxic granules through their membranes to kill them. However, killer T-cells are not always effective because cancer cells are inherently good at avoiding detection. During treatment, their genes tend to mutate, giving them novel ways to evade the human immune system.
Mojo Vision’s smart contact lens has finally made the leap to human testing, bringing the future of AR a major step closer.
This video is the 1st of a series of “What is Aging” webinars that aims to unravel what aging is, how we age, why we age, and how to reverse it.
We welcome Jason C. Mercurio, MFE, Dr. Jose Cordeiro, and Dr. Ian Hale to discuss the topic.
Stanford University researchers have discovered a rapid and sustainable way to synthetically produce a promising cancer-fighting compound right in the lab. The compound’s availability has been limited because its only currently known natural source is a single plant species that grows solely in a small rainforest region of Northeastern Australia.
The compound, designated EBC-46 and technically called tigilanol tiglate, works by promoting a localized immune response against tumors. The response breaks apart the tumor’s blood vessels and ultimately kills its cancerous cells. EBC-46 recently entered into human clinical trials following its extremely high success rate in treating a kind of cancer in dogs.
Given its complex structure, however, EBC-46 had appeared synthetically inaccessible, meaning no plausible path seemed to exist for producing it practically in a laboratory. However, thanks to a clever process, the Stanford researchers demonstrated for the first time how to chemically transform an abundant, plant-based starting material into EBC-46.

At a luxury resort in the Swiss Alps, wealthy investors and scientists are cooking up plans to push the limits of the human lifespan.
Microsoft has revised its mitigation measures for the newly disclosed and actively exploited zero-day flaws in Exchange Server after it was found that they could be trivially bypassed.
The two vulnerabilities, tracked as CVE-2022–41040 and CVE-2022–41082, have been codenamed ProxyNotShell due to similarities to another set of flaws called ProxyShell, which the tech giant resolved last year.
In-the-wild attacks abusing the shortcomings have chained the two flaws to gain remote code execution on compromised servers with elevated privileges, leading to the deployment of web shells.
