Caught in the act: Images capture molecular motions in real time

15-Jul-2019 - Researchers have used ultra-high-speed x-ray pulses to make a high-resolution "movie" of a molecule undergoing structural motions. The research, published in Nature Chemistry, reveals the dynamics of the processes in unprecedented detail -- capturing the excitation of a single electron in the ...

Spaced-out nanotwins make for stronger metals

06-Nov-2018 - Researchers from Brown University and the Institute of Metals Research at the Chinese Academy of Sciences have found a new way to use nanotwins -- tiny linear boundaries in a metal's atomic lattice that have identical crystalline structures on either side -- to make stronger metals. The ...

How order first appears in liquid crystals

24-May-2018 - Liquid crystals undergo a peculiar type of phase change. At a certain temperature, their cigar-shaped molecules go from a disordered jumble to a more orderly arrangement in which they all point more or less in the same direction. LCD televisions take advantage of that phase change to project ...

A new way to stimulate cellular recycling process

18-May-2018 - Brown University researchers studying the biology of aging have demonstrated a new strategy for stimulating autophagy, the process by which cells rebuild themselves by recycling their own worn-out parts. In a study the researchers show that the approach increased the lifespans of worms and flies, ...

New approach to measuring stickiness could aid micro-device design

09-Mar-2018 - Brown University engineers have devised a new method of measuring the stickiness of micro-scale surfaces. The technique could be useful in designing and building micro-electro-mechanical systems (MEMS), devices with microscopic moving parts. At the scale of bridges or buildings, the most ...

Enzyme shown to regulate inflammation and metabolism in fat tissue

12-Jan-2018 - The human body has two primary kinds of fat--white fat, which stores excess calories and is associated with obesity, and brown fat, which burns calories in order to produce heat and has garnered interest as a potential means of combating obesity. Now, a study led by Brown University researchers ...

Researchers develop key power-splitting component for terahertz waves

01-Jul-2016 - One of the most basic components of any communications network is a power splitter that allows a signal to be sent to multiple users and devices. Researchers from Brown University have now developed just such a device for terahertz radiation -- a range of frequencies that may one day enable data ...

In wide range of species, longevity proteins affect dozens of the same genes

15-Apr-2016 - Whether a creature is a worm, a fly, a mouse, or a human, death inevitably awaits. And not only do these organisms share a common fate, but also, according to a new study, they may share some of the specific mechanisms of mortality. The researchers found that in all four species, there are 46 ...
