Soapberry bugs changes their body shape and reproductive strategy depending on nutrient. @aphanotus.bsky.social @colbycollege.bsky.social is revealing how these traits have evolved! #PASEDB2025 #polyphenism #soapberrybug #nutrient

NASA is being told to cancel 19 *active* missions to save $6B, which looks to be less than the ICE *hiring/retention* budget going forward.

I need people to let that sentence sink into their bones for a minute.

Exciting on a technical level. Def should reignite ethical conversations around human gene editing.

Okay, wow. Systemic in utero gene editing could in theory be used after fetal genetic screening. www.pnas.org/doi/10.1073/...

How Scientific Journals Became MAGA’s Latest Target Evidence of political bias, corporate influence and fraud has made the field vulnerable.

How a discovery in Yellowstone National Park led to the development of PCR - Richmond Scientific A discovery in Yellowstone National Park led to the development of PCR, the gold-standard COVID-19 tests used to fight the global pandemic.

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪

How many insects can you see in this photo? Believe it or not, there are five. This termite alate fell victim to four perfectly camouflaged assassin bug nymphs (Reduvius tarsatus) Their bodies are covered with minute setae that trap grains of sand and various debris, making them virtually disappear.

Z is for Zebrida, completing the alphabet of #CrabAZ!

This pretty little guy rides around on fire urchins, which are venomous to us. But the crab nibbles its tube feet! Its body shape and colors both match and contrast with the urchin.

But it's not over yet! Come back tomorrow for a bonus post 🦀🧪🦑

Reminder that NIH grants are NOT reckless spending. They are extremely competitive. The mean success rate of all grants is <24%. Far lower for R01's that are the lifeblood of most academic labs. All the data can be found here:

Although the hits keep coming, we must continue to fight for the future of science. Whether in your classrooms or in your neighborhoods, get the word out about the breakdown of our federal institutions. Make sure that people know what this means for their future and the future of the country.
