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...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Many-body localization and quantum many-body scars: The strong and weak form of ergodicity breaking
多体定位 量子多体疤痕 遍历性断裂 强弱形式
2023/4/23
The fate of an isolated quantum many-body system has attracted much attention in the past decade. One of the most important issues is whether such a system can reach thermalization under its own dynam...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Peakon Models I: Scalar Form
标量形式 Peakon模型 标量峰值模型
2023/5/8
In this talk, I will majorly focus on the scalar peakon models developed in the last 30 years. Most integrable peakon equations come from the negative order flow in the hierarchy. I will take some exa...
Microbes that cause cavities can form superorganisms able to ‘crawl’ and spread on teeth（图）
蛀牙 微生物 超有机体
2023/7/7
Across-kingdom partnership between bacteria and fungi can result in the two joining to form a “superorganism” with unusual strength and resilience. It may sound like the stuff of science fiction, but ...
High in the atmosphere of Venus, a swirl of sulfur-containing clouds blankets the planet. Dark spots in these clouds correspond with areas of high ultraviolet light absorption, but researchers have ye...
One of the hallmarks of Alzheimer’s disease is the presence of neurofibrillary tangles in the brain. These tangles, made of tau proteins, impair neurons’ ability to function normally and can cause the...
CLOUD discovers new way by which aerosols rapidly form and grow at high altitude（图）
CLOUD 气溶胶 高海拔地区 快速形成

Aerosol particles can form and grow in Earth’s upper troposphere in an unexpected way, reports the CLOUD collaboration in a paper1 published today in Nature.
Fossils may need air to form（图）
Fossils air to form
2019/11/15
Some of the world's most exquisite fossil beds were formed millions of years ago during time periods when Earth's oceans were largely without oxygen.That association led paleontologists to believe tha...
Geoscientists have discovered the first direct evidence that material from deep within Earth's mantle transition zone -- a layer rich in water, crystals and melted rock -- can percolate to the surface...
‘Gyroscope’ Molecules Form Crystal That’S Both Solid And Full Of Motion（图）
Gyroscope Molecules Form Crystal Both Solid Full Of Motion
2018/1/31
Molecular machines, much smaller than single cells, may one day be able to deliver drugs to kill cancer cells or patrol your body for signs of disease. But many applications of these machines require ...
When Israeli scientist Daniel Shechtman first saw a quasicrystal through his microscope in 1982, he reportedly thought to himself, “Eyn chaya kazo” – Hebrew for, “There can be no such creature.”But th...

Scientists Discover More Effective,and Potentially Safer,Crystalized Form of DDT
Scientists More Effective Potentially Safer Crystalized DDT
2017/7/21
A team of scientists has discovered a new crystal form of DDT that is more effective against insects than the existing one. Its research, which appears in the journal Angewandte Chemie, points to the ...
Uncovering the answer to an age-old question:how do snowflakes form?
Uncovering the answer age-old question snowflakes form
2017/7/20
More than 400 years ago, renowned mathematician and scientist Johannes Kepler speculated about the creation of one of nature’s most angelic and unique shapes: the six-sided snowflake. Although atoms w...

Molecules form gels cells sense respond to stress
2017/3/30
A specific protein inside cells senses threatening changes in its environment, such as heat or starvation, and triggers an adaptive response to help the cell continue to function and grow under stress...
