Fluid mechanics researchers from Brown University and the University of Toulouse found that surfactants give the celebratory drink its stable and signature straight rise of bubbles.
MIT neuroscientists have found a way to reverse neurodegeneration and other symptoms of Alzheimer’s disease by interfering with an enzyme that is typically overactive in the brains of Alzheimer’s pati...
Many birds’ feathers are remarkably efficient at shedding water — so much so that “like water off a duck’s back” is a common expression. Much more unusual are the belly feathers of the sandgrouse, esp...
An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star like cotton candy as it pulls in material from a nearby star. As the disk spins, it whips u...
To manage atmospheric carbon dioxide and convert the gas into a useful product, Cornell scientists have dusted off an archaic – now 120 years old – electrochemical equation. The group aims to thwart t...

Materials known as metal-organic frameworks (MOFs) have a rigid, cage-like structure that lends itself to a variety of applications, from gas storage to drug delivery. By changing the building blocks ...
The United Kingdom Atomic Energy Authority (UKAEA) and the US Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) have entered a strategic research partnership to better understand the...
Plastics are incredible materials with properties invaluable to the functioning of our modern world. They are strong, flexible, versatile, long-lasting and inexpensive. In particular, high-density pol...
A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer, which harnesses quantum mechanical phenomena to solve cert...
Scientists discover a new way of sharing genetic information in a common ocean microbe（图）
海洋微生物 共享 遗传信息 原绿球菌 光合生物 基因转移

From the tropics to the poles, from the sea surface to hundreds of feet below, the world’s oceans are teeming with one of the tiniest of organisms: a type of bacteria called Prochlorococcus, which des...
A team of scientists at the Whitehead Institute for Biomedical Research and the Broad Institute of MIT and Harvard has systematically evaluated the functions of over 5,000 essential human genes using ...
When NASA’s 990-pound Dragonfly rotorcraft reaches the Selk crater region – the mission’s target touchdown spot – on Saturn’s moon Titan in 2034, Cornell’s Léa Bonnefoy '15 will have helped to make it...
