New paper with @beatezein.bsky.social & @jedalong.bsky.social:

⭐A new data-driven paradigm for the study of avian migratory navigation⭐

We propose how the multi-modal multi-scale nature of navigation could be studied w/ data mining, machine learning & AI.

Avian navigation has fascinated researchers for many years. Yet, despite a vast amount of literature on the topic it remains a mystery how birds are able to find their way across long distances while ...

📊 Latest HUXt forecast shows 2 CMEs from AR4274 arriving on 12 Nov at ~4 & 15UT respectively. AR4274 is delivering a one-two punch!⚡️🥊 G2+ storm conditions increasingly likely. Aurora prospects strong for northern UK despite poor weather forecast.

Direct hit! A beautiful, full-halo CME is now leaving the Sun following the X1.2 flare, and it's heading right for us. We'll have to see what the models think about this one, but we now have two Earth-directed CMEs coming at us and a good chance for geomagnetic storms Nov 11-12.

daily for weeks we hear the noise of literally thousands of pink footed geese travelling south filling the skies over the Scottish Highlands

This is only a small bunch this morning, you hear them coming long before you see them !

4 days of seismic records from a seismic station in Jamaica shows Hurricane Melissa roaring towards the island.

Hurricanes increase the amplitude of ocean waves which beat on the coast and sea floor. These produce Rayleigh waves that can be seen as increasingly thick “wiggles” in seismic records 🧪
Seismic recording that shows horizontal lines with a slight wiggle to them. Horizontal lines across the page that get thicker with wiggles near the bottom of the page. The horizontal lines are very thick. The page is almost black because of the thickness of the lines.

Evidence from 14 research funding programmes confirms that early winners tend to keep winning (Matthew effect). But the idea that an early setback makes you stronger later doesn’t replicate widely.
buff.ly/UEtcRd4
eLife Assessment This important study reports the results of efforts to replicate two phenomena of significant interest to early-career scientists and scientific policymakers: the Matthew effect and the early-career setback effect. Several previous studies of these effects have focused on early-career researchers with grant proposals that fell just below or just above a funding threshold. Those just above the threshold were more likely to be successful when they applied for funding later in the career (an example of the well-known Matthew effect), while those just below were more likely to go on to have stronger publication records (the early-career setback effect). In this study the Matthew effect was found to be robust across funders, and to generalize from those close to the funding threshold to the whole population. The early-career setback effect was not robust across funders and did not generalize to the whole population. The evidence reported is convincing.

😎 First glimpses from space!

The new #Copernicus Sentinel-4 mission has delivered its first preliminary images during commissioning.

Sentinel-4’s spectrometer is hosted on @eumetsat.int's MTG-S1 satellite 🧪🌍

@josefaschbacher.esa.int @ec.europa.eu @esaearth.esa.int
The new Copernicus Sentinel-4 mission has delivered its first images, highlighting concentrations of atmospheric nitrogen dioxide, sulphur dioxide and ozone. Despite being preliminary, these images mark a major milestone in Europe’s ability to monitor air quality all the way from geostationary orbit, 36 000 kilometres above Earth. This image depicts tropospheric nitrogen dioxide with clear pollution hotspots visible along the Mediterranean coast and over Italy’s Po Valley. This image presents a vertical column density of sulphur dioxide. A distinct plume can be seen emerging from Mount Etna in Italy and drifting south-eastwards over the sea. Although Etna is currently relatively calm, much larger plumes are typically observed during periods of heightened volcanic activity. In addition to natural emissions from volcanoes, sulphur dioxide is also released through human activities, particularly from ships burning high-sulphur fuels and power plants using brown coal. This image shows a vertical column of ozone. While ozone high up in the stratosphere plays a crucial role in shielding life on Earth from harmful ultraviolet radiation, ozone in the lower atmosphere acts as a pollutant, contributing to poor air quality and respiratory problems. The overall ozone levels here are within the expected range. This image of Europe and part of North Africa is based on the first Earth radiance spectra measured by Sentinel-4. The false-colour image, generated by assigning the signals in specific spectral ranges to red, green and blue, shows the land, ocean and clouds as expected.

ESA astronaut Samantha Cristoforetti seen here during a helicopter training course with the German Bundeswehr, Germany's federal defence forces. She participated in a three-week training programme at the International Helicopter Training Centre in Bückeburg, Germany. The San Rafael glacier, top of image, is one of the most actively calving glaciers in the world. It calves west towards the Pacific Ocean and into an arc-shaped lake, Laguna San Rafael, visible directly to the left of the glacier. Latest results from the ESA’s Swarm satellite constellation highlight the dynamic nature of Earth’s magnetism. In the northern hemisphere there are two areas where the magnetic field is particularly strong – one around Canada and the other around Siberia. Since the launch of Swarm in 2013 the Canadian strong field region on the left has decreased while the Siberian strong field region on the right has increased. A spiral galaxy featuring a bright, glowing core that is crossed by a horizontal bar of yellowish light. Spiral arms emerge from each end of this bar and wrap around it, creating a disc that is stretched out to the right. Some areas, mostly along the arms, glow pink where stars are forming in nebulae. Webs of dark reddish dust also follow the arms.

I've received an 'exclusive' invite to try Nature's new 'research assistant', which will burn down a forest to provide a 'summary of the paper' I'm reading and I have SUCH exciting news for them, that's called an 'abstract' and the actual authors already wrote it for me, no forest-burning required.
