Gotta catch ‘em all: Agar microchambers for high-throughput single-cell live imaging

Constraining motile microorganisms for live imaging often requires costly microfluidics or optical traps to keep them in view. We used patterned stamps and agar to make versatile, inexpensive “microchambers” and offer a way to predict the right chamber size for a given organism.

Agave Sisalana for distributed production of absorbent media for menstrual pads in semi-arid regions

Agaves are robust, draught tolerant plants that have been cultivated for their high-strength fibers for centuries and they hold great promise as a crop in the face of increasing water scarcity associated with a warming planet. Meanwhile, millions of women lack access to sanitary products to safely manage their menstruation particularly in low- and middle-income countries characterized by a dry climate. To address this issue, we show a processing route that transforms the leaves of the succulent Agave sisalana into a highly absorbent and retentive (23 g/g) material. The process involves delignification combined with mechanical fluffing to increase affinity for water and porosity, respectively. This process leads to a material with an absorption capacity exceeding those found in commercially available products such as menstrual pads. Finally, the carbon footprint water usage associated with this process is comparable with common alternatives with the added benefit that it can be carried out at small scales while remaining environmentally sustainable. Our work represents a step towards distributed manufacturing of essential health and hygiene products based on a local bioeconomy.

NASA Scientific Visualization Studio - Zonal Climate Anomalies 1880-2022

A visualization of zonal temperature anomalies. The latitude zones are 90N-64N, 64N-44N, 44N-24N, 24N-EQU, EQU-24S, 24S-44S, 44S-64S, 64S-90S. The anomalies are calculated relative to a baseline period of 1951-1980. This version is in Fahrenheit, an alternate version in Celsius is also available.

The anomalies are calculated relative to a baseline period of 1951-1980. This version is in Celsius, an alternate version in Fahrenheit is also available. The visualization presents zonal temperature anomalies between the years 1880-2022. The visualization illustrates that the Arctic is warming much faster than other regions of the Earth.These temperatures are based on the GISS Surface Temperature Analysis (GISTEMP v4), an estimate of global surface temperature change. The latitude zones are 90N-64N, 64N-44N, 44N-24N, 24N-EQU, EQU-24S, 24S-44S, 44S-64S, 64S-90S. Anomalies are defined relative to a base period of 1951-1980. The data file used to create this visualization can be accessed here.The Goddard Institute of Space Studies (GISS) is a NASA laboratory managed by the Earth Sciences Division of the agency’s Goddard Space Flight Center in Greenbelt, Maryland. The laboratory is affiliated with Columbia University’s Earth Institute and School of Engineering and Applied Science in New York.
