New modeling of nuclear device to deflect or destroy asteroids en route to Earth（图）
小行星 核装置 天体物理学
2024/2/1
The same high energy density that makes nuclear energy a clean and efficient source of power could make it a good alternative to defend the planet against catastrophic asteroid impacts. NASA demonstra...
Researchers create synthetic species without biochemistry, find they operate according to Darwinian evolutionary principles.
New research from Cornell and the Smithsonian Institution deepens the geological understanding of Earth’s continents by testing and ultimately eliminating a popular hypothesis about why continental an...
On the eve of Earth Day, Brown climate scientist outlines solutions for a warming world（图）
气候科学 全球变暖 气候变化
2023/6/26
Kim Cobb, a Brown University professor and director of the Institute at Brown for Environment and Society, spoke about the need to act on climate change, urging that action must be taken collaborative...
Can humans endure long-term living in deep space?The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agri...
A yearslong effort to launch Cornell-made satellite technology into a neighboring solar system is making a terrestrial stop at the Intrepid Sea, Air and Space Museum in New York City.
Partly melted rocks under Earth’s surface offer insights into what makes plate tectonics possible（图）
地球表面 板块构造 构造地质学
2023/6/26
Using seismic waves, scientists detect widespread partially molten rock hidden under the Earth’s tectonic plates in a new way, a step in settling a long-held geological debate that has big implication...
Moving water and earth（图）
颗粒形状 河流恢复 海岸侵蚀
2023/6/19
As a river cuts through a landscape, it can operate like a conveyer belt, moving truckloads of sediment over time. Knowing how quickly or slowly this sediment flows can help engineers plan for the dow...

Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say（图）
黑洞生长 超大质量黑洞 兹威基瞬态设施 天文观测
2023/6/9
Earlier this year, astronomers were keeping tabs on data from the Zwicky Transient Facility, an all-sky survey based at the Palomar Observatory in California, when they detected an extraordinary flash...
New research analyzing pieces of the most ancient rocks on the planet adds some of the sharpest evidence yet that Earth’s crust was pushing and pulling in a manner similar to modern plate tectonics at...
When glacial ice sheets melt, something counterintuitive happens to sea levels. Logic might suggest that nearby levels would rise, but instead they fall.
A group of international scientists led by Cornell is – more rigorously and systematically than ever before – evaluating if and how the stratosphere could be made just a little bit “brighter,” reflect...
At the end of this century, scientists believe that megadroughts – extended drought events that can last two decades or more – will be more severe and longer than they are today in western United Stat...
