Bacteria can anticipate the seasons: Photoperiodism in cyanobacteria
Photoperiodic time measurement is the ability of plants and animals to measure differences in day versus night length (photoperiod) and use that information to anticipate critical seasonal transformat...

Incredibly proud to share this work, almost 6 years in the making, out this month in Science!!! 🎇
We've known for over a century that eukaryotes of all kinds anticipate the seasons (think: hibernation, flowering, reproduction!), but what about bacteria?🦠

SO HAPPY to share our new paper in @currentbiology.bsky.social! Using volumetric EM, we found daily shifts in synapses, vesicles, and mitochondria that accompany neuronal remodeling, linking structural plasticity to changes in how s-LNv neurons influence their targets

The findings of a study in Nature Climate Change show that artificial light at night disrupts the fundamental energetic constraints on ecosystem metabolism, warranting the inclusion of light pollution in global change and carbon–climate feedback assessments. go.nature.com/44cCKWm 🧪

Indigenous lands must be recognised as part of climate policy, says Brazilian minister
Indigenous lands must be recognised as part of climate policy, says Brazilian minister
Sonia Guajajara tells Cop30 the rights of traditional communities must be maintained in the face of exploitation by the mining industry
Countries must recognise the demarcation of Indigenous lands as a key component of tackling the climate crisis, and civil society must help in the defence of such lands against mining interests, Brazil’s minister for Indigenous peoples has said.
Sonia Guajajara, a longtime Indigenous activist before being appointed a minister by President Lula da Silva, said: “[Among the goals of the Cop30 summit is] a request that countries recognise the demarcation of Indigenous lands as climate policy.” Continue reading...

I wonder how my cat rationalizes it when I am out of town for trips
perhaps "ah mother is once more on one of her long hunting trips"
but most likely "that damn idiot got lost again, didn't she"

When you publish a website that posts the names and photos of scholars who have written or said things you disagree with and encourage people to surveil and harass them, you are not, in fact, a “free speech” organization.
It is quite simply dishonest to describe TPUSA as a “free speech” organization and not even mention the “Professor Watchlist,” as NPR just did. Reporting on a crime does not entail adopting the victim’s views.

needless to say I'm a big fan of the latest review by Mingxu Fang (now at OSU), @partchlab.bsky.social, Andy LiWang and Susan Golden!
if you haven't read it yet and you're interested in circadian clocks and/or bacteria, definitely check it out!

O entendimento da Corte é que crimes contra a democracia são imperdoáveis pela Constituição, tanto por indulto presidencial quanto por anistia aprovada no Congresso.
