How does low-impact development help manage stormwater?

Credit: Unsplash/CC0 Public Domain Cities can have many benefits when designed well, including reducing carbon imprints. Another way cities can improve their environmental impact is by using “low-impact development” with regard to water management. It is also called “green stormwater infrastructure.” The Soil Science Society of America’s (SSSA) September 1st Soils Matter blog explores how … Read more

How nerve cells in the brain connect during development

The model produces a realistic network of neurons. Credit: ETH Zurich / Stan Kerstjens ETH Zurich researchers have developed a model that explains how nerve cells in the brain connect during development. Their model reveals that the crucial factor is progressive cell division. This process leads naturally to the formation of molecular addresses that lets … Read more

Drosophila embryonic development at single-cell resolution

A new atlas that maps the continuum of embryo development in fruit flies has gone beyond, thanks to machine learning. Credit: Isabel Romero Calvo/EMBL Scientists have constructed the most complete and detailed single-cell map of embryo development in any animal to date, using the fruit fly as a model organism. Published in Science, this study, … Read more

Does China’s research and development funding reach the right firms?

Credit: Unsplash/CC0 Public Domain Chinese investments in research and development (R&D) have burgeoned since the turn of the century, increasing more than tenfold in absolute terms since 2000 and reaching a high of 2.4 percent of GDP in 2020. As the world’s second biggest spender on R&D after the United States, China is certainly a … Read more

Students from poorer regions rate Sustainable Development Goals as more important than those from richer regions do

Credit: Unsplash/CC0 Public Domain In 2015, the member states of the United Nations adopted the 2030 Agenda for Sustainable Development. The central element is the 17 Sustainable Development Goals (SDGs). These include “Zero Hunger”, “Clean Water”, “Responsible Consumption” and “Life Below Water”. The SDGs relate to all three pillars of sustainability, ie social, economic and … Read more

Turning X chromosome ‘off and on again’ critical for oocyte development

Image showing artificial ovary (left), where in vitro-generated female germ cells (magenta) enter meiosis (yellow cells) to become oocytes with the help from supporting cells (cyan). This process is four times more efficient when the X chromosome is correctly turned OFF and ON again during germ cell development. Also shown (top right) are oocytes at … Read more
