There’s A Giant Cruise Ship In The Harbor Outside Work That’s Just Been Slowly Spinning In Circles

Gather round, children, and let me tell you the tale of the sturddlefish. In the year 2019 in the mythical land of Hungary’s Research Institute for Fisheries and Aquaculture, some scientists were trying to save some endangered fish. The Russian sturgeon and American paddlefish are distantly related species that are both endangered. The scientists were trying to induce gynogenesis in the sturgeon. 

This is a type of parthenogenesis (single parent reproduction) where sperm triggers the embryo growth, but doesn’t contribute genetic material. In any type of parthenogenesis, the offspring is basically a clone of the mother. 

The scientists needed to have sperm interact with the eggs without inseminating them. So they used paddlefish sperm. Since paddlefish diverged from sturgeons 184 million years ago, the scientists figured that there was no chance of insemination. 

Much to their surprise, the paddlefish sperm did fertilize the sturgeon eggs, creating the hybrid sturddlefish. This was not expected at all due to his distantly related the parent species are. There were two sturddlefish populations from the same breeding. One that was 50% sturgeon and paddlefish and one that had twice as much sturgeon due to chromosome doubling. Only about 2/3 of the sturddlefish survived longer than a month and only about 100 survived past a year. Hybrids often have health problems that limit their lifespans. Given how long-lived the parent species are, a healthy sturddlefish could live for a long time. 

The sturddlefish will live out their lives in the research institute and the scientists have no plans of making more. I don’t know if any of them are still alive. For a brief time, a new lifeform will have come into existence by sheer accident and will soon be extinct. May they Rest In Peace

if you don't do anything else today,

Please have a moment of silence for the people who were killed instead of freed when news of emancipation finally reached the furthest corners of the american south.

have another moment for the ledgers, catalogs, and records that were burned and the homes that were destroyed to hide the presence of very much alive and still enslaved people on dozens of plantations and homesteads across the south for decades after emancipation.

and have a third moment for those who were hunted and killed while fleeing the south to find safety across the border, overseas, in the north and to the west.

black people. light a candle, write a note to those who have passed telling them what you have achieved in spite of the racist and intolerant conditions of this world, feel the warmth of the flame under your hand, say a prayer of rememberance if you are religious, place the note under the candle, and then blow it out.

if you have children, sit them down and tell them anything you know about the life of oldest black person you've ever met. it doesn't have to be your own family. tell them what you know about what life was like for us in the days, years, decades after emancipation. if you don't know much, look it up and learn about it together.

This is Juneteenth.

Moths are more efficient pollinators than bees, shows new research

Moths are more efficient pollinators at night than day-flying pollinators such as bees, finds new research from the University of Sussex, published March 29 in PLOS ONE.

Amid widespread concern about the decline of wild pollinating insects like bees and butterflies, University of Sussex researchers have discovered that moths are particularly vital pollinators for nature.

Studying 10 sites in the South East of England throughout July 2021, the Sussex researchers found that 83% of insect visits to bramble flowers were made during the day. While the moths made fewer visits during the shorter summer nights, notching up only 15% of the visits, they were able to pollinate the flowers more quickly.

As a result, the researchers concluded that moths are more efficient pollinators than day-flying insects such as bees, which are traditionally thought of as “hard-working.” While day-flying insects have more time available to transfer pollen, moths were making an important contribution during the short hours of darkness.

i learned about a stupid looking bird today and i cant stop laughing

its called a crested satinbird (cnemophilus macgregorii)
