In this week’s episode of Radio Corona, we explore why the US has no idea how to manage all the testing data it’s collecting. Last week, reporter Neel Patel wrote about how the US’s decentralized public health system means there are no common standards for reporting testing data. That could create chaos in attempts to fight the pandemic,...
Each of our cells is surrounded by a complex membrane that functions as a biological border, letting ions and nutrients such as salt, potassium and sugar in and out. The guards are membrane proteins, which do the hard work of permitting or blocking the traffic of these molecules.

Researchers have discovered that a fasting-mimicking diet could be more effective at treating some types of cancer when combined with vitamin C. In studies on mice, researchers found that the combination delayed tumor progression in multiple mouse models of colorectal cancer; in some mice, it caused disease regression.
A new tool using cutting-edge technology is able to distinguish different types of blood clots based on what caused them, according to a new study.
In a new study, researchers have discovered two important functions of a protein called RTEL1 during cell division. The researchers hope that the new knowledge will help to find new cancer treatments.
A new study examining the effect of the immune receptor known as Toll-like Receptor 4, or TLR4, on how memory functions in both the normal and injured brain has found vastly different cellular pathways contribute to the receptor's effects on excitability in the uninjured and injured brain. Further, the researchers found novel mechanisms for how TLR4 regulates memory function in the normal,...

The news: In its latest Community Standards Enforcement Report, released today, Facebook detailed the updates it has made to its AI systems for detecting hate speech and disinformation. The tech giant says 88.8% of all the hate speech it removed this quarter was detected by AI, up from 80.2% in the previous quarter. The AI can remove content automatically if the system has high confidence that it...
Finding could help solve mystery of where plastic goes after it leaks into the sea Hundreds of thousands of tonnes of mismanaged waste could be blowing ashore on the ocean breeze every year, according to scientists who have discovered microplastics in sea spray.The study, by researchers at the University of Strathclyde and the Observatoire Midi-Pyrénées at the University of Toulouse, found tiny...
What would you do if the person standing next to you suddenly screamed and ran away? Would you be able to carry on calmly with what you're doing, or would you panic? Unless you're James Bond, you're most likely to go for the second option: panic.
The National Research Council of Canada said Tuesday it will work with a Chinese company to try to develop its potential vaccine for COVID-19 more...
