Scientists develop new land surface model to monitor global river water environment

Climate change and human activities, including heat emission, nitrogen (N) emission and water management, are altering the hydrothermal condition and N transport in the soil and river systems, thereby affecting the global nitrogen cycle and water environment.

“We need to assess the impacts of these human activities on global river temperature and riverine N transport,” said Prof. Xie Zhenghui from the Institute of Atmospheric Physics of the Chinese Academy of Sciences. “Quantitative assessment can not only improve our understanding of the material and energy cycle that occur in response to anthropogenic disturbances, but also contribute to protecting river ecosystems.”

Xie and his collaborators from the Chinese Academy of Sciences incorporated the schemes of riverine dissolved inorganic nitrogen (DIN) transport, river water temperature, and human activity into a land surface model, and thus developed a land surface model CAS-LSM. They applied the model to explore the impacts

The Black Scientists, Doctors, and Entrepreneurs Changing The Beauty Industry

In a moment marked by frank cultural conversations about race, identity, and representation, cosmetic companies have responded by revamping their approaches to address audiences that the industry has for too long ignored and underserved. In 2017, Lancôme expanded its Teint Idole Ultra Range to 40 shades, famously followed by Fenty Beauty—and that number has now become a benchmark. But creating makeup in a greater diversity of skin tones is just the tip of the iceberg in an industry-wide transformation that’s been more than a decade in the making.

The real story lies in part with Balanda Atis, a Black cosmetic chemist and head of L’Oréal USA’s Multicultural Beauty Lab. In 2007, Atis knew that the foundation category for women of color was lacking, so she and her team set out on an international tour of 57 countries to collect data on the tonal composition of skin of color. “We used

Nobel winning women hope to inspire a new generation of scientists

On hearing that they had been awarded a Nobel Chemistry Prize for their groundbreaking work on gene-editing Jennifer Doudna and Emmanuelle Charpentier said they hoped it would inspire a new generation of women in science.  

Charpentier and Doudna are the first all-woman team to receive a Nobel science prize and become the sixth and seventh women to be honoured for their research in chemistry since the first awards in 1901. 

Pernilla Wittung Stafsheden of the Royal Swedish Academy of Sciences, which is responsible for selecting the Nobel laureates in chemistry, said the prize to two female laureates was “a historic moment”. 

The Nobel is for the pair’s development of CRISPR-Cas9, a tool that allows scientists to snip DNA and edit the genetic code of animals, plants and microorganisms.

The scientists said they hoped that the Nobel recognition would also help light up a path for young women entering a field
