I'm frequently asked if we can use XRM imaging to study Arabidopsis, and the answer is absolutely yes. The pollen grains were segmented using basic grayscale thresholding. This scan used the 4X lens, stayed tuned for results from the 20X.

Well, it's official. After our paper last year (onlinelibrary.wiley.com/doi/full/10....), the Slender-billed Curlew is officially declared Extinct today.

Scientists dream of describing new species, not writing their obituary and epitaph, knowing that they are gone forever #ornithology

Congratulations!!!

A timetree of Fungi dated with fossils and horizontal gene transfers - Nature Ecology & Evolution Combining fossil-based and molecular calibrations with data on horizontal gene transfer events, the authors develop a time-calibrated phylogeny of Fungi. This timescale, which integrates analytic uncertainties, suggests an older age of crown Fungi (1,401–896 million years ago), as well as a minimum age for ancient interactions involving fungi and the algal ancestors of embryophytes in terrestrial ecosystems (1,253–797 Ma).

Our latest, led by Edu Ocaña-Pallarès and @ssolo.bsky.social, a timescale for fungal phylogeny that wrangles calibration from the unstructured fossil record of fungi and a history of horizontal gene transfers

Detail of the the front of the painting. Katydids, grasshoppers, leafhoppers, and crickets are playing instruments and dancing, while mantids and other insects are carrying flowers

The full painting; katydids, mantids, and more lead the procession. In the middle is grasshoppers carrying a box, and in the rear are wasps offering up a comb of brood. Many are carrying flowers and dancing

‘Thrilled’ Indonesian scientists celebrate return of fossil trove from the Netherlands The items to be returned, which include Java Man, were collected during the colonial era

A momentous occasion: 'Java Man' is going back to Indonesia, along with more than 28,000 other fossils that Dutch scientist Eugène Dubois collected during the colonial era.

Fossil found on Skye is new species of fanged Jurassic reptile Experts say the lizard-like creature, which has been given the Gaelic name Breugnathair elgolensis, had lived about 167 million years ago.

Is it a lizard? Is it a snake? Maybe a 'false snake'?? As that's what its name means in Gaelic!

Hello to Breugnathair, a new fossil from the Jurassic of Skye with a curious mix of snake & lizard features, showing that early squamate evolution was complex

I'm sorry you had a bad experience with therapy but it is a complicated process and therapists really vary in their approaches, so it may be worth trying again with some additional research (depending on what practioners you can access of course).

A good therapist should be able to acknowledge that your circumstances are the main cause of your problems and help you address them in constructive ways, for example this is how they should approach people who have PTSD.

The problem is its hard to distinguish initally when a therapist is bad or inappropriate for you from when therapy is "working" but making you feel in the short term worse. This is why medication can be the best short term and acute intervention because it can work quickly and effectively.

I don't know your specific circumstances but fwiw it's basically the norm for therapy to initially make you feel worse because you are actually addressing and working through your feelings rather than burying them.

Bryophytes hold a larger gene family space than vascular plants - Nature Genetics A super-pangenome analysis incorporating 123 newly sequenced bryophyte genomes reveals that bryophytes exhibit a larger number of unique and lineage-specific gene families than vascular plants.

Decay stages of Jurassic wood debris from Scotland: evidence for the coevolution of fungal rot, arthropods and the nurse log strategy A key feature of extant conifer forests is the high percentage of seeds that germinate and establish on dead wood; in some forests, this can exceed 90%. This deadwood can act as an ideal nursery for...
