"The #ESA Biomass satellite’s P-band synthetic aperture radar is capable of slicing through even the densest forest canopies to measure tree trunks, branches, and stems – which is where most forest carbon is stored. These measurements act as a proxy for carbon storage" #carbon

[ESA Earth Observation @ESA_EO]

Tomorrow @ESA 's Biomass mission will launch - its data will be essential in understanding the role of forests in the carbon cycle.
But the work happening on the ground, in the deep of tropical forests remains key: why?
Despite their sophistication, spaceborne instruments do not directly measure forest biomass or biodiversity. Ground validation is essential – especially in tropical forests.

A new Science study finds that different dendritic segments of a single neuron follow distinct rules. The results challenge the idea that neurons follow a single learning strategy and offer a new perspective on how the brain learns and adapts behavior

[NASA Astronomy Picture of the Day @apod]

Beautiful emission nebula NGC 6164 was created by a rare, hot, luminous O-type star, some 40 times as massive as the Sun. Seen at the center of the cosmic cloud, the star is a mere 3 to 4 million years old. In another three to four million years the massive star will end its life in a supernova explosion. Spanning around 4 light-years, the nebula itself has a bipolar symmetry. That makes it similar in appearance to more common and familiar planetary nebulae - the gaseous shrouds surrounding dying sun-like stars. Also like many planetary nebulae, NGC 6164 has been found to have an extensive, faint halo, revealed in this deep image of the region. Expanding into the surrounding interstellar medium, the material in the halo is likely from an earlier active phase of the O star. This gorgeous telescopic view is a composite of extensive narrow-band image data, highlighting glowing atomic hydrogen gas in red and oxygen in greenish hues, with broad-band data for the surrounding starfield. Also known as the Dragon's Egg nebula, NGC 6164 is 4,200 light-years away in the right-angled southern constellation of Norma.

[Understanding Animal Research @animalresearch]

What animal research was behind the 2024 Nobel Prize awarded for the discovery of microRNA?

The 2024 Nobel Prize in Physiology or Medicine was awarded to Victor Ambros and Gary Ruvkun for their discovery in nematode worms that tiny pieces of RNA, called microRNAs, play a key role in controlling and regulating gene activity in animals and plants.

The C. elegans worm was also in the spotlight for other Nobel prizes, including the discovery of the genetic regulations of organ development and programmed cell death in 2002 and of RNA interference in 2006.

The work being recognised currently can help scientists better understand embryological development, normal physiology and diseases such as cancer.
