3 Questions: A new model of nervous system form, function, and evolution（图）
神经系统形态 神经科学模型 Brady·Weissbourd
2023/6/5
How does animal behavior emerge from networks of connected neurons? How are these incredible nervous systems and behaviors actually generated by evolution? Are there principles shared by all nervous s...
When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions. Previous ...
With plants as a model, studying the ‘complexity and reproducibility’ of developmental biology（图）
植物 发育生物学 分子机制

Nearly paper-thin, often with a complex two-dimensional shape, leaves may number into the hundreds of thousands on an organism like a white oak. Yet typically, each leaf appears quite similar in form.
Scientists develop the largest, most detailed model of the early universe to date（图）
早期宇宙模型 黎明女神 Thesan 辐射
2023/6/9
It all started around 13.8 billion years ago with a big, cosmological “bang” that brought the universe suddenly and spectacularly into existence. Shortly after, the infant universe cooled dramatically...
With a little twist and the turn of a voltage knob, Cornell researchers have shown that a single material system can toggle between two of the wildest states in condensed matter physics: the quantum a...
Planckian metals have the potential to power high-temperature superconductors, quantum computers and a host of other next-generation technologies. However, these “strange” metals – in which electrical...

Model predicts urban development greenhouses gasses fuel urban floods
2021/4/9
When rain began falling in northern Georgia on September 15, 2009, little did Atlantans know that they would witness epic flooding throughout the city. Neighborhoods such as Peachtree Hills were subme...

High-resolution ocean model looks sea turtles lost years
2021/3/26
A detailed global ocean model simulation by scientists at the National Center for Atmospheric Research and other institutions has given scientists insights into where baby sea turtles may go...
One reason it's so difficult to produce effective vaccines against some viruses, including influenza and HIV, is that these viruses mutate very rapidly. Mutation allows them to evade the antibodies ge...
Model could improve design of vaccines, immunotherapies（图）
Model improve design vaccines immunotherapies
2020/11/6
The body's immune system defeats diseases by sensing foreign invaders, such as bacteria or viruses, then mounting a response against them.But how immune cell receptors work together to sense multiple ...
The best-known particle in the lepton family is the electron, a key building block of matter and central to our understanding of electricity. But the electron is not an only child. It has two heavier ...
Steering a (virtual) hurricane: New model gives scientists more control（图）
Steering a (virtual) hurricane New model scientists more control
2020/4/3
What if Hurricane Sandy had dealt New Jersey a glancing blow in 2012 instead of hitting it nearly head on? Or if the historic storm had made landfall farther south or north? What if the storm was smal...
Mega-cloud from Canadian wildfires will help model impacts of nuclear war（图）
Mega-cloud Canadian wildfires model impacts nuclear war
2019/10/21
Extreme wildfires in British Columbia, Canada, pumped so much smoke into the upper atmosphere in August 2017 that an enormous cloud circled most of the Northern Hemisphere – a finding reported in the ...

Model predicts bat species potential spread Nipah virus
2019/10/23
Since its discovery in 1999, Nipah virus has been reported almost yearly in Southeast Asia, with Bangladesh and India the hardest hit. In a new study, published in PLOS Neglected Tropical Diseases, sc...
New computer model shows how proteins are controlled “at a distance”
New computer model shows proteins controlled at a distance
2017/3/14
Enzymes are large proteins that are involved in virtually every biological process, facilitating a multitude of biochemical reactions in our cells. Because of this, one of the biggest effort...
