Boeckeler lived from 1803 to 1899. The literature citation that this species is known from that place is from 1887. Mid 1800s, hard to be more specific.

The label was written in German Kurrentschrift, an old style of handwriting. The long s in "Lesum" and the V and the k in Vegesack are unusual, and the first e rather looks like an "a". But there is no alternative at the Lesum river. Johann Otto Boeckeler is known to have collected in NW Germany.

Old #herbarium sheets come with perks and challenges. I love to figure out what is written. For this particularly hard example I got lucky because the collection was cited with the old species name in an old paper. It's "An der Lesum bei Vegesack" in #Bremen, Germany. #HerbariumLife #CuratorLife

If you are a student or young scientist who needs publications for their degree and to get a stable job, the incentive is high. Competition is insane and people become desperate to succeed.

The harmonious regularity of the inflorescence of this #Earina valida #orchid from #NewCaledonia is beautiful, even in a #herbarium specimen. The plant must look spectacular in nature. #HerbariumLife #CuratorLife

However, we are fully aware that the collections are always in need of updating, and this Index will not be the final version. But it's a huge update.
Recuration requires a balance of reasonably stable taxonomy and time to update the collections and out database. So there is plenty left to do.

This new Index features the integration of the gymnosperm collections (which were missing before) and lately the complete recuration of the whole order Asparagales and the Vitaceae. Many other taxa were overhauled, created and synonymized.

The #herbaria at the NHM London are currently busy preparing several large projects that shape the future of the collections. After around 10 years, we have a new physical Index to our General #Herbarium collections reflecting updates from recuration based on research and visitors' annotations.

This bill does not apply to people with a disability per se but to terminally ill. There are criteria for that.

Springer Nature book on machine learning is full of made-up citations


Would you pay $169 for an introductory ebook on machine learning with citations that appear to be made up?

If not, you might want to pass on purchasing Mastering Machine Learning: From Basics to Advanced, published by Springer Nature in April. 

Based on a tip from a reader, we checked 18 of the 46 citations in the book. Two-thirds of them either did not exist or had substantial errors. And three researchers cited in the book confirmed the works they supposedly authored were fake or the citation contained substantial errors.

Humanism and Aesop's Fables How do the ancient Greek stories link to humanist ethics today?

Aesop's Fables were written over 2500 years ago. Many of them provide a great way to teach about humanist ethics and how we might live well together. We've provided some suggestions for where to start. understandinghumanism.org.uk/articles/hum...

To use a highly technical term, this is dodgy as f**k. Publication ethics matter--without them the scientific literature ceases to be reliable.

Small note: it's the outer layer of the seed thats smelly, not the "fruit". Gymnosperms don't have fruits because the seeds are not covered by a carpel that eventually develops into a fruit.

You are seeing from the wrong direction being the common people and their needs
You need to see it from the view of private equity: healthcare is perfect way of making money because people pay everything to get rid of pain or not to die. New drugs exist also solely to make more $$$.

Farage generates clicks and viewing rates (because his fans and his haters will engage) and therefore income from advertisers. Media are businesses who have to maximise profits, not report facts, educate or try to seek solutions. It's about making money, always and only.

How many carpenter bees can fit into a squash flower? Three. I count three bee butts.
Happy World Bee Day! We need bees (and not just honeybees)!

Trump Administration Cancels Scores of Grants to Study Online Misinformation

Foreign adversaries are pumping disinformation into our social media networks, but we know very little about the consequences let alone how to ameliorate them.

For years, Republicans have harassed us for studying this. Now, NSF has canceled all funding. It’s a profound lapse in national security.

NEW INVESTIGATION: A private equity-fueled for-profit chain slashed patient care for years while its executives got rich. So we scraped every malpractice, personal injury, and wrongful death case tied to Steward hospitals.

And we found how mothers, newborns, and others paid the ultimate price.

close-up of a recently opened milkweed flower. its five light green petals point towards, creating a bowl around the central reproductive column, or gynostegium. this structure is a fused stamen + carpel complex, white on top of the column & dark green underneath, with 5 light green butresses. five purple and white corona hoods extend away from the column, though two are obscured behind petals. one nearby flower is also blooming, but they are both surrounded by unopened buds.

The worst part is that AI images and texts can be used for good but are much more abundantly and likely used to produce -at best- trivialities and light entertainment and -at worst- fake news, propaganda, mindless consumption, and complete surveillance.
