Black hole 'donuts' are actually 'fountains'

Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut ...

Using a material's 'memory' to encode unique physical properties

A new study published in Science Advances found that certain types of materials have a "memory" of how they were processed, stored, and manipulated. Researchers were then able to use this memory to control how a material ...

Hero proteins are here to save other proteins

Researchers at the University of Tokyo have discovered a new group of proteins, remarkable for their unusual shape and abilities to protect against protein clumps associated with neurodegenerative diseases in lab experiments. ...

Pull-chain 'polymer' solves puzzle of complex molecular packing

(PhysOrg.com) -- Sometimes the simplest things hold the key to understanding complex effects. It turns out that a humble metal pull-chain -- just like those used on ceiling fans -- can be a pretty good model for complex properties ...

A chain mail fabric that can stiffen on demand

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and the California Institute of Technology (Caltech), United States, have developed a new type of 'chain mail' fabric that is flexible like cloth ...

Pass the lycopene: Scientist can protect supplements inside food

(PhysOrg.com) -- A Purdue University food scientist has developed a way to encase nutritional supplements in food-based products so that one day consumers might be able to sprinkle vitamins, antioxidants and other beneficial ...

Nanobowls serve up chemotherapy drugs to cancer cells

For decades, scientists have explored the use of liposomes—hollow spheres made of lipid bilayers—to deliver chemotherapy drugs to tumor cells. But drugs can sometimes leak out of liposomes before they reach their destination, ...

Powering a pacemaker with a patient's heartbeat

Implantable pacemakers have without doubt altered modern medicine, saving countless lives by regulating heart rhythm. But they have one serious shortcoming: Their batteries last only five to 12 years, at which point they ...
