Neither desolate nor empty: Deep-sea floor teems with life
The Arctic deep sea harbors significant oil and natural gas reserves along with valuable resources such as rare earths and metals. Climate change and melting ice are facilitating access to these resources, which presents economic opportunities but al.....»»
New language encodes shape and structure to help machine learning models predict nanopore properties
A large number of 2D materials like graphene can have nanopores—small holes formed by missing atoms through which foreign substances can pass. The properties of these nanopores dictate many of the materials' properties, enabling the latter to sense.....»»
Q&A: Getting serious about atmospheric methane removal
Carbon dioxide, the most important man-made greenhouse gas, gets most of the attention in efforts to stem the effects of climate change. While methane is considered a much more potent greenhouse gas, it breaks down into carbon dioxide and water in th.....»»
2D graphene spin valve leverages van der Waals magnet proximity for efficient spintronics
Graphene, particularly in its purest form, has long been considered a promising material for developing spintronic devices. These devices leverage the intrinsic angular momentum (i.e., spin), as opposed to the charge, of electrons to transmit and pro.....»»

Ytterbium thin-disk lasers pave the way for sensitive detection of atmospheric pollutants
Alongside carbon dioxide, methane is a key driver of global warming. To detect and monitor the climate pollutants in the atmosphere precisely, scientists at the Max Planck Institute for the Science of Light (MPL) have developed an advanced laser tech.....»»
Can AI improve plant-based meats? Using mechanical testing and machine learning to mimic the sensory experience
Cutting back on animal protein in our diets can save on resources and greenhouse gas emissions. But convincing meat-loving consumers to switch up their menu is a challenge. Looking at this problem from a mechanical engineering angle, Stanford enginee.....»»
Opinon: Shell"s legal victory is disappointing—but this is not the end for corporate climate litigation
In the first ruling of its kind, the Dutch Hague District Court in 2021 ordered a fossil fuel company, Shell, to slash its emissions. This decision would have required the oil and gas giant to cut its emissions by 45% by 2030 (compared with 2019 leve.....»»
