The mystery of 𝐴𝑠𝑝𝑖𝑑𝑖𝑢𝑚 𝑎𝑚𝑒𝑟𝑖𝑠𝑡𝑜𝑛𝑒𝑢𝑟𝑜𝑛 is solved as researchers reveal its true origin is Mexico, not Cuba, correcting over a century of botanical misidentification and renaming it 𝐶𝑡𝑒𝑛𝑖𝑡𝑖𝑠 𝑎𝑚𝑒𝑟𝑖𝑠𝑡𝑜𝑛𝑒𝑢𝑟𝑜𝑠.

arXiv will no longer accept review articles and position papers unless they have been accepted at a journal or a conference and complete successful peer review.

This is due to being overwhelmed by a hundreds of AI generated papers a month.

Yet another open submission process killed by LLMs.

Can a native species become “invasive?”

There are numerous cases where a native species, when reacting to a novel condition, can become problematic for ecosystems and biodiversity. The example given here is hay-scented fern (Dennstaedtia punctilobula).

The genomic footprints of wild Saccharum species trace domestication, diversification, and modern breeding of sugarcane
Genomic analyses of 390 accessions reveal the domestication history of highly polyploid sugarcane and the wild contributors to its diversification and to modern cultivars.

Oh my. This seems like an impossible task with all the nuance and different approaches to authorship across fields and even sub-disciplines. The incentive to leave early career technicians and others off of papers as authors is going to be high. www.nature.com/articles/d41...
Google Scholar tool gives extra credit to first and last authors
Researchers welcome the initiative, but say it doesn’t go far enough to capture the nuance of researcher productivity and impact.

Humor is so personal and it does not fail gracefully; if it's not funny to you, it's just not funny, no matter how much someone else is laughing. When one writes humor one accepts there are people for whom it is just not going to work - but those who laugh will love it for making them laugh.
I remember loving the humor in Redshirts so much I would stop and read portions out loud to my family. They never seemed to enjoy it as much as I hoped they would.

New Bacterial Species Discovered in Cyclosorus Soil
In a remarkable contribution to the field of microbiology, researchers have announced the discovery of a novel actinomycete strain, cg5^T, extracted from the rhizosphere soil of Cyclosorus parasiticus, a fern species located in Xiangtan City, Hunan province, China. This strain, with its unique genetic and biochemical properties, is set to redefine our understanding of the Amycolatopsis genus, which is recognized for its potential in antibiotic production and various biotechnological applications.

How do cells communicate when it’s hot? (FAULKNER_J26DTP) | Doctoral Training Partnership
Plant cells are connected to their neighbours via ‘tubes’ called plasmodesmata, creating an interconnected cytoplasm that joins cells within and between tissues and organs.

A great visit to Coastal Maine Botanical Gardens. Amazing weather for early October.

The trolls welcomed all.

Below is one of five trolls, Roskva.

The trolls were designed and installed, with the help of local workers, by Danish artist Thomas Dambo. He has installations all over the world.
