This is an astounding example of passed down information and tool usage. The tool in this case is a medicinal paste the orangutan made by chewing specific leaves they don't otherwise eat to make a poultice to heal a wound. #science https://www.bbc.co.uk/news/science-environment-68942123.amp

As we approach the launch of ESA’s EarthCARE mission, we caught up with some of the scientists, engineers and experts behind the mission.
With the climate crisis increasingly tightening its grip, ESA’s Earth Cloud Aerosol and Radiation Explorer mission (EarthCARE) will shed new light on the complex interactions between clouds, aerosols and radiation in Earth’s atmosphere.
EarthCARE is the largest and most complex Earth Explorer mission. It comes at a critical time in the development of kilometre-scale resolution, global climate models and will provide an important contribution to an improved understanding of cloud convection and its role in Earth’s radiation budget.
EarthCARE is an ESA mission, but it has been developed as a cooperation between ESA and JAXA, the Japanese Space Agency.
This video features interviews with: Pavlos Kollias from Stony Brook University – McGill University, Thorsten Fehr, EarthCARE Mission Scientist at ESA, Robin Hogan, Senior Scientist at ECMWF, Dirk Bernaerts, EarthCARE Project Manager at ESA, Kotska Wallace, Mission and Optical Payload Manager at ESA, Tomomi Nio, EarthCARE Mission Manager at JAXA, Eiichi Tomita, EarthCARE/CPR Project Manager at JAXA, Ulla Wandinger, Senior Scientist at Leibniz Institute for Tropospheric Research and Bjoern Frommknecht, EarthCARE Mission Manager at ESA.

Europe’s newest rocket soon launches, taking with it many space missions each with a unique objective, destination and team at home, cheering them on. Whether launching new satellites to look back and study Earth, peer out to deep space or test important new technologies in orbit, Ariane 6’s first flight will showcase the versatility and flexibility of this impressive, heavy-lift launcher. Read on for all about EXOpod Nova, then see who else is flying first.

ESA is committed to almost halve its greenhouse gas emissions linked to energy consumption by 2025 compared to 2019 levels. But how can ESA keep accelerating the use of space for the sustainable development of society while reducing its emissions?

I can't imagine anyone who actually believes in astrology (that is, really thinks its true and not a bit of a fun read in the tabloids) being at all persuaded by this, but at the same time, I have to admire the dedication to really, really test things thoroughly. Needless to say, there are no surprises here.

Spektrum-Podcast: Viel Wirbel um das Sonnen-Vitamin
A few weeks ago, a team of engineers carefully extracted ESA's EarthCARE satellite from its protective transport container, initiating a meticulous process of inspection, testing and preparation for its liftoff later this month from the Vandenberg launch site in California.
Amidst an extensive checklist of tasks, was a rigorous effort to guarantee that the satellite is in pristine condition, underscoring the thorough attention to detail essential to making the satellite ready for launch.

Last week, Ariane 6’s central core – the main body of the rocket – was stood tall at the launch zone and connected to its two solid-fuel boosters. This exciting moment means only one thing: it’s the start of the first launch campaign.
The main stage and upper stage make up the core stage, and they were autonomously driven at 3 km/h from the rocket assembly building to the launch pad, 800 m away. Then lifted by a crane, the Ariane 6 core was stood upright on the launch table.
The two boosters were transported to the launch pad on a specially designed truck and then configured with the rocket body, now holding it upright.
Ariane 6 is due to launch in summer 2024. The heavy-lift rocket will inaugurate a new era of autonomous European space transportation, powering Europe into space to realise its ambitions on the world stage. It will lift off from a modern launch complex at Europe’s Spaceport in French Guiana, carrying with it not just a variety of spacecraft, but also European goals for prosperity and autonomy.

ESA's newly graduated astronauts reach the end of one year of rigorous basic astronaut training. Discover the journey of Sophie Adenot, Rosemary Coogan, Pablo Álvarez Fernández, Raphaël Liégeois, Marco Sieber, and Australian Space Agency astronaut candidate Katherine Bennell-Pegg. Selected in November 2022, the group began their training in April 2023.
Basic astronaut training provides the candidates with an overall familiarisation and training in various areas, such as spacecraft systems, spacewalks, flight engineering, robotics and life support systems as well as survival and medical training. They received astronaut certification at ESA’s European Astronaut Centre on 22 April 2024.
Following certification, the new astronauts will move on to the next phases of pre-assignment and mission-specific training - paving the way for future missions to the International Space Station and beyond.

This otherworldly, ever-changing landscape is what the Sun looks like up close. ESA's Solar Orbiter filmed the transition from the Sun's lower atmosphere to the much hotter outer corona. The hair-like structures are made of charged gas (plasma), following magnetic field lines emerging from the Sun's interior.
The brightest regions are around one million degrees Celsius, while cooler material looks dark as it absorbs radiation.
This video was recorded on 27 September 2023 by the Extreme Ultraviolet Imager (EUI) instrument on Solar Orbiter. At the time, the spacecraft was at roughly a third of the Earth’s distance from the Sun, heading for a closest approach of 43 million km on 7 October.
On the same day that this video was recorded, NASA’s Parker Solar Probe skimmed just 7.26 million km from the solar surface. Rather than directly imaging the Sun, Parker measures particles and the magnetic field in the Sun’s corona and in the solar wind. This was a perfect opportunity for the two missions to team up, with ESA-led Solar Orbiter’s remote-sensing instruments observing the source region of the solar wind that would subsequently flow past Parker Solar Probe.
Spot the moss, spicules, eruption and rain
Lower left corner: An intriguing feature visible throughout this movie is the bright gas that makes delicate, lace-like patterns across the Sun. This is called coronal ‘moss’. It usually appears around the base of large coronal loops that are too hot or too tenuous to be seen with the chosen instrument settings.
On the solar horizon: Spires of gas, known as spicules, reach up from the Sun’s chromosphere. These can reach up to a height of 10 000 km.
Centre around 0:22: A small eruption in the centre of the field of view, with cooler material being lifted upwards before mostly falling back down. Don’t be fooled by the use of ‘small’ here: this eruption is bigger than Earth!
Centre-left around 0:30: ‘Cool’ coronal rain (probably less than 10 000 °C) looks dark against the bright background of large coronal loops (around one million degrees). The rain is made of higher-density clumps of plasma that fall back towards the Sun under the influence of gravity.

Quels changements en cours des #pollinisateurs ?
La biodiversité change rapidement, mais ces changements sont surtout connus pour quelques groupes très étudiés, comme les oiseaux ou les mammifères. Les insectes en général ont reçu beaucoup moins d’attention, à l’exception peut-être des abeilles domestiques ou des papillons : https://podcastfichiers.college-de-france.fr/porcher-20240216.m4a
Les données disponibles pour retracer les variations d’abondance des pollinisateurs au cours du passé récent sont donc très disparates, et leur analyse produit parfois des résultats non concordants. Récemment, ces variations d’abondance des insectes ont fait l’objet de controverses scientifiques, avec plusieurs études montrant un déclin, voire un effondrement des populations d’insectes, tandis que d’autres ne détectaient pas de changements significatifs, et parfois même des augmentations. Les suivis standardisés des insectes, grâce notamment aux sciences participatives, peuvent contribuer à mieux objectiver ces changements.
