Lessons learned from addressing myths about Zika and yellow fever outbreaks in Brazil

When disease epidemics and outbreaks occur, conspiracy theories often emerge that compete with the information provided by public health officials. A new study finds that information used to counter myths about Zika in Brazil not only failed to reduce misperceptions but also reduced the accuracy of people's other beliefs about the disease.

Scientists make human organs transparent to allow 3D maps at cellular level

For the first time, researchers managed to make intact human organs transparent. Using microscopic imaging they could revealed underlying complex structures of the see-through organs at the cellular level. Resulting organ maps can serve as templates for 3D-bioprinting technologies. In the future, this could lead to the creation of on demand artificial organs for many patients in need.

10,000 steps a day: Not a magical formula for preventing weight gain

For years now, 10,000 steps a day has become the gold standard for people trying to improve their health -- and recent research shows some benefits can come from even just 7,500 steps. But if you're trying to prevent weight gain, a new study suggests no number of steps alone will do the trick.

'Multitasking' AI tool to extract cancer data in record time

To better leverage cancer data for research, scientists are developing an artificial intelligence (AI)-based natural language processing tool to improve information extraction from textual pathology reports. In a first for cancer pathology reports, the team developed a multitask convolutional neural network (CNN) -- a deep learning model that learns to perform tasks, such as identifying key words in a body of text, by processing language as a two-dimensional numerical dataset.

Huge bacteria-eating viruses close gap between life and non-life

Bacterial viruses, called bacteriophages, are simple genetic machines, relying on their bacterial hosts to replicate and spread. But scientists have found hundreds of huge phages that carry a slew of bacterial proteins that the phages evidently use to more efficiently manipulate their microbial hosts. These proteins include those involved with ribosomal production of proteins and the CRISPR bacterial immune system, as if the phages are a hybrid between living microbes and viral machines.

Antibiotics discovered that kill bacteria in a new way

A new group of antibiotics with a unique approach to attacking bacteria has been discovered, making it a promising clinical candidate in the fight against antimicrobial resistance. The newly-found corbomycin and the lesser-known complestatin have a never-before-seen way to kill bacteria, which is achieved by blocking the function of the bacterial cell wall. The discovery comes from a family of antibiotics called glycopeptides that are produced by soil bacteria.
