Extinction Declared
A species of ray, so rare it has only ever been recorded once back in the late 1800s, has been declared extinct after an assessment by an international team led by Charles Darwin University (CDU). The loss of the Java Stingaree, a small relative of stingrays, is the first marine fish extinction as a result of human activity.
This news comes as the International Union for Conservation of Nature (IUCN) released its updated Red List of Threatened Species.
The Java Stingaree (Urolophus javanicus) was known only from a single specimen collected in 1862 from a fish market in Jakarta, Indonesia.
The team conducted new modeling encompassing all available information on the species which has revealed the Java Stingaree as extinct.CDU Ph.D. Candidate and lead assessor, Julia Constance said a range of issues had contributed to the Java Stingaree's disappearance.
"Intensive and generally unregulated fishing is likely the major threat resulting in the depletion of the Java Stingaree population, with coastal fish catches in the Java Sea already declining by the 1870s," Ms Constance said.

The Sea is Purple at Piraeus
Erik Lindner
The sea is purple at Piraeus.
A flag creeps out of the campanile when the wind turns.
A man steps over a dog. A woman stoops to rub her eyelid.
In an umbrella shop an umbrella falls off the counter.
A pigeon perching on a narrow branch falls off, flutters, and settles again. The berry out of reach at the end of the twig. The branch that bends, the ruff that bulges when the pigeon shuffles along.
A girl gets on the metro with a desk drawer.
On the thick sand by the breakers an angler slides his rod out horizontally a bike beside him on its kickstand.
He stands with legs apart as if he’s peeing. Birds’ footprints in the sand. The rod arches over the sea.

Inspired by this post by @alex-just-vibing. PaliRev values the contribution of all people to the liberation of Palestine, and we encourage you to share this around your schools or with others to give accessible options for us all to show solidarity for the Palestinian people.
[image id: an image with a white background, bordered on the bottom left and top right with green, corner illustrations, an olive garden branch drawing on the bottom right, and a drawing of a boy sitting down with a backpack leaning on him, looking downwards sadly on the top right. there is a low opacity palestinian flag behind black text reading "HOW DO I SUPPORT PALESTINIAN RESISTANCE IF I CAN'T DONATE?" below this is a list in smaller black text, bulleted with light green arrows. the list reads:
"- Wear shirts, pins, keffiyehs, anything outwardly pro Palestine.
Email your Representatives, Congress, White House. Tell the people in charge you want a ceasefire.
Talk to your local library about holding an educational night about the genocide and/or Palestinian culture.
Make schoolwork about Palestine! Writing about news? Focus on Palestine. Making questions for a test? Use Palestine as an example.
Find social media accounts for your representatives and schools, and make a fuss. Comment and @ them!
Show up to local actions (i.e. protests), join and organization, and follow Palestinian journalists! (next line) - Motaz Azaiza, Plestia Alaqad, Hind Khoudary, Bisan Owda -
Educate yourself on anti-Palestine talking points (Palestine toolkit) and how to refute them in a calm manner.
Speak up! It's scary, but don't let other people's bigotry go unchecked. You'll find that other people agree, and speak up from your example.
Don't engage with people unwilling to learn. Your goal is to educate people who are and make those comfortable with genocide feel UNCOMFORTABLE."
below this in light grey text reads "@PALIREV.WEB". /end id.]

Aaron Bushnell it's trending. His name is trending. His screams of Free Palestine weren't in vain. Because Tumblr can try and censore palestinian blogs, and keep palestine from trending, but we will always find a way to bring revolution to the world.
Fucking Free Palestine

Attention Christians - THIS is what Jesus would do. Put his body on the line, speak truth to power, and demand justice for the starving and oppressed. 🙌
Thank you, @christiansforafreepalestine, for being an example of true decency and faith in action.
“Our scriptures say ‘woe to you, who eat while others go hungry!” they called out to senate staff.
Saying “Congress won’t eat until Gaza eats,” over 60 Christians from across the U.S. are nonviolently blockading the Senate Cafeteria to pressure the Senate and their staffers to support a permanent ceasefire in Gaza, restore aid to UNRWA, and end military funding to Israel. #CFPAction

Protecting Polar Bears With Improved Radar Technology - Technology Org
New Post has been published on https://thedigitalinsider.com/protecting-polar-bears-with-improved-radar-technology-technology-org/
Protecting Polar Bears With Improved Radar Technology - Technology Org
Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results.
Researchers from Simon Fraser University (SFU) and Brigham Young University (BYU), collaborating with Polar Bears International, hope that improving detection tools to locate dens—which are nearly invisible and buried under snow—will help efforts to protect mother polar bears and their cubs.

Results of a pilot study aimed at improving den location in Churchill, Manitoba—using ARTEMIS Inc., an imaging system that relies on Synthetic Aperture Radar, or SAR—are published in the journal URSUS just ahead of Polar Bear Week (Oct. 29 – Nov. 4).
The team found that SAR increased den detection by more than 20 per cent, or 66 per cent, compared with the industry’s current 45 per cent accuracy rate using the aerial Forward Looking Infrared (FLIR) system as a den-detection tool.
“Our airborne imaging radar system has multi-band, interferometric, and polarization capabilities at microwave frequencies able to penetrate snow,” says SFU engineering science professor Bernhard Rabus, who holds an Industrial Research Chair in Synthetic Aperture Radar. “The system can ‘see’ both the top snow surface, the den roof surface and inside the den cavity.”
“While our method is still in its research and testing phase, an operational version is expected to be able to extrapolate from the radar signatures of live bears in the open, combined with computer modelled den cavity radar signatures, to develop a robust match filter detection for airborne multi-channel SAR data to detect polar bears reliably inside their dens.”
Unlike aerial FLIR, SAR technology performs well regardless of temperature and weather conditions, which is crucial in the Arctic, thus SAR may be an effective tool to guide conservation efforts for this vulnerable and iconic species.
“This report advances Synthetic Aperture Radar as a promising method for polar bear den detection, which is critical for protecting polar bears alongside human activity,” says Geoff York, senior director of research and policy at Polar Bears International.
“Brigham Young University and Simon Fraser University have been invaluable research partners, and we’re excited about the possibility of SAR in the Arctic as it performs well in all weather conditions.”
David Long, electrical engineering professor and director of BYU’s Center for Remote Sensing, noted that the research provided BYU undergraduate Capstone students “an opportunity to do original research to identify and locate polar bears using radar. This is the first time this has ever been done, and we have great confidence this can be used in the Arctic areas to detect polar bears in the snow.”
Denning is the most vulnerable time for polar bears, and with increased industry activity in the region, there is a need for more accurate tools that can detect polar bear dens to avoid disturbing them during this critical time.
Polar bears cubs are born blind with only a light layer of fur to protect them from the cold. They remain dependent on their mothers, living in winter dens under the snow. They are able to emerge from the den in spring when they have grown enough to withstand the harsh Arctic conditions.
A mother bear’s inability to successfully raise cubs contributed to the 40 per cent decline of the Southern Beaufort Sea subpopulation between 2000-2010. A critical part of polar bear conservation is keeping mothers and cubs safe while also addressing other threats such as climate change.

It’s snowing and some college student drew a giant dick on the least-walked part of the courtyard. I’m in love with humans and how they just find dicks funny for like no reason. Humans are wonderful creatures

I literally do not care what the Bible says about any political issue. I am not Christian. Christian scripture should have zero effect on my life or my personal freedoms.
