Folk were really into the post I made about Tandie, the zoo lion with a (then) undergrown mane due a period of time on testosterone blockers. He's having quite the glow up this summer.

But!

Did you know that manes are hormone dependent in both sexes of lion?

Let's talk about maned lionesses!

To recap the previous post quickly: the existence of a mane, and it's color, appear to be pretty heavily androgen-dependent. Neutered males or males put on testosterone blockers, like Tandie was, will drop their manes - but like Tandie, if taken off the meds, it will generally grow it back. Darker manes are indicative of higher testosterone levels, and long/lush manes are generally a good signal of a male's fitness and mate quality. Females seem to show a preference for males with longer, darker manes and other males will preferentially avoid scuffles with them. (Yes, as many comments have pointed out, that means Scar was actually a hunk. Do with that as you will.)

The fascinating thing about androgens being linked to manes in lions is that it goes both ways - females with higher levels will also grow manes!

Mane growth in females lions is most commonly seen with elderly animals who have stopped cycling and are basically in lion menopause. And they have to get pretty old for it to happen - captive lions generally only live into their late teens and early second decade, and most of the maned ladies I know about started growing manes around like, seventeen.

Not all old female lions grow manes, but some of the career cat people I've talked to said it happened to about a quarter of the females they've worked with over the years. Which... is an interesting contrast to the news articles about Zuri, who we'll meet in a bit, that breathlessly reported in 2022 that her mane growth "left scientists baffled."

Old lady lion manes are just... precious. They grow in first at the chest and then around the sides or on the back of the head, but they don’t normally get the length, density, and connectivity seen in the mane of an adult male. It leaves the lionesses manes kind of awkward, in the way I associate with very young males, and they're absolutely adorable. Prepare yourself for the photo spam.

I have to start with Daisy, because she's the only maned lioness I've had the privilege to meet in person.

I don't know exactly when she started growing her mane, but she was over 20 years old when she passed in 2019 with these luscious locks.

Here's another female at the same facility, named Adeena. On the left is a photo of her from 2021, on the right is from this spring (I think she's mid-sneeze in the photo). She turns 20 in October.

If you've heard about maned lionesses before, it’s probably because of Zuri, at Topeka. She’s the most recent one to get media coverage and she went a little viral.

(Just a side note here, but I have some strong feelings about knowledge loss in the exotic animal management world due to political/philosophical schisms. This is one of those topics where it's clear: Topeka told a reporter that the zoo had “never" heard of this happening before, but it's common enough to be well known as a thing in other sectors of the exotic cat world. There's so much expertise and knowledge being lost due to infighting between accrediting groups, and it drives me up a wall).

Anyway. Zuri had one of the best manes I've seen on an elderly lioness. It grew long and lush and she totally could have done shampoo commercials. I mean, look at this.

Zuri lived with her sister, who didn't grow a mane in her old age. Here's the two of them together, Zuri on the left, Asante on the right.

We don't completely know what's going on with these golden girls to cause them to grow manes. It's theorized to be related to the end of estrus and higher levels of androgenic hormones, although it's not clear if that's just due to lower levels of other hormones during "meownopause" or if there's something else also going on.

There was some speculation with Zuri's mane growth that it was caused by the death of the male she lived with, in some biological need to "take over the role." The zoo dismissed that idea pretty quickly, and it makes sense, although there is one other instance where I've heard of that happening before.

The cat people I've talked to say that older lionesses who grow manes don't tend to act differently - they're not taking over new social roles in their prides or anything. Sometimes they can be less active, or be a little more nervous around males, and want to be left alone more, but it was emphasized to me that those behaviors could also just be associated with the fact that manes tends to develop in elderly lionesses.

The mane growth can happen pretty quickly, as we saw in the photos I've posted of Tandie over the last year. Here's Bridget, from the Oklahoma Zoo. The left photo was taken in March of 2017 and the right in November - look how much hair she gained over six months!

The zoo did some research into what might have cause Bridget's mane growth, and found that she had elevated levels of androstenedione, which is a hormone that can be converted by the body into either testosterone or estrogen, depending. In AFAB people, it's known to have a masculinizing effect. The zoo theorized that this was the cause of her mane growth, and that the elevated levels might have been caused by a benign tumor. Fascinatingly, though, blood draws revealed that her testosterone levels were the same as her mane-less sister, Tia.

Tia is on the left in the photo below, Bridget and the beginnings of her mane are on the right. Bridget was 17 when her mane started growing in.

I don't think there's any formal hypothesis that there might be a genetic component to lionesses growing manes in old age, but it's interesting to note that one of Tia's daughters, Zari, also grew a mane. (And she grew it young! It started around age 13, interestingly, also right after their male died). She's on the left in the photo below.

And to circle back around to where we began: Tandie is related to a number of maned ladies! His father, Xerxes, was Bridget's son; Zari was Xerxes' half-sister.

Here's a few more beautiful maned ladies to leave you with. In order, Ngala, Pepper, Skye, and Dandy Lion.

Next up, and last in this lion mane series, is the story of five younger lionesses in Botswana who not only have manes but also express a range of masculine behaviors.

‘WHO VOTED FOR THIS?’ : TRUMP OBSTRUCTS CANCER RESEARCH FUNDING Trump has given orders to freeze ALL federally funded medical research in America. This includes research to treat: Cancer, Alzheimer's, Diabetes, Arthritis, Obesity, Drug Addiction, Depression, Childhood Leukemia, Heart Disease, etc. All of us know someone who is a afflicted with a medical condition that science is trying to cure, or at least lessen its severity. Who in their right mind would want to put a freeze on such important work? Notice Trump's priorities. He's not interested in lowering the cost of housing, or reducing middle and lower income Americans' taxes, or the price of groceries. Why? Because he's laser focused on more important stuff like: stopping life-saving medical research, worsening the climate crisis, reigniting inflation by mass deportations, increasing prescription drug prices, and of course, America's most urgent need of all — renaming the Gulf of Mexico. The man needs to have his head examined. Oh, ...darn. He just put a freeze on medical research into finding out what the hell is wrong with him!

I just found out I'm gonna have to leave the United States.

Long post incoming. You have been warned.

Hey all. You all probably have different levels of knowledge about who I am, what I do, etc, so lemme catch you all up. I'm Ryan. I'm from São Paulo, Brazil. At the age of 17, I was accepted to study biochemistry at UCLA. I left São Paulo, the only place I had ever lived in, and moved to the US in 2021 to start my biochemistry degree. After 4 years of hard work, I'm graduating this week. I always planned to stay in the US after graduation to work, get my PhD in chemistry, and just live my life.

And I was on my way to do that, until you-know-who walked into office a few months ago. That was when my entire field started being absolutely gutted. My professors were fired. PhD programs stopped existing. My hardest working friend in my major was accepted to UCLA's biochem PhD program and had her acceptance rescinded due to lack of funding. She was absolutely devastated. Like me, like the rest of us, all she wanted to do was be a scientist.

All the post-graduation jobs that I applied to stopped existing. I was hoping to get a student visa extension, which can be done if you get a job in your field post graduation. I was on my way to do that. I got some job interviews, most of which went really well. But none of that mattered, because those entire programs vanished into thin air. I checked in on applications to jobs I was more than qualified for, only to find out they had stopped existing altogether.

For the last year, I've worked in a biochemical engineering research lab, and things have been disappearing from the lab too. Reagents that we need no longer being affordable. The lyophilizer broke and was never fixed. The research we do is on drug delivery systems. I was working on self-assembling drugs that could've become active once in target cells. But my lab, like many others, suddenly became starved of resources and funding. The lab, my absolute favorite place in the world, just couldn't sustain as many experiments and students as it once did.

I slowly came to the realization that getting a job wasn't enough for me to stay in the US. Even if I did get a job, the chances of me being laid off unexpectedly were very high, and I'd have to scramble to go back to Brazil. I'd always be low on the priority list of employees to keep. I'm an entry-level scientist and an immigrant from Latin America. Once funding was cut, I'd be first to go. I'm seeing the writing on the wall and it's telling me there's nowhere left in the US for me to be.

Not to mention the constant fear of being detained by ICE for no reason, or not being able to speak up on any social issues because of constant surveillance. If you've noticed me being more silent than usual on certain world issues, it's not because I've lost my beliefs. It's because I've been living in fear of being unfairly persecuted for what I say. There have been raids at elementary school graduations for fuck's sake. I've always been in the US legally with a valid visa, but that's no longer enough to be safe. Simply existing as a Latina is dangerous. I have no family in the US, they're all back in Brazil. I'm alone in this country. If I got snatched off the street, that'd be it for me.

I did everything right. You're always told that if you work hard, go to college, and get a good degree, you'll be fine. Well, I did that. I aced my high school in São Paulo so hard that I was the first person from there to get into UCLA, the #1 public university in the US. I came to UCLA as a biochemistry major, and I stuck through it. Biochem is one of the most dropped majors at UCLA. I got into a research lab, and I'm even winning a commencement award at my graduation this week for excellence in my field. I maintained legal status. No criminal record.

I did everything right, but it wasn't enough. It wasn't enough because I was born in Latin America, and because I wanted to become a scientist in 2025. All I wanted to do was be a biochemist. I always thought that if I didn't get a job, it'd be because there was someone more qualified than me, not because my entire field was getting choked out of existence. Can't say I was expecting that!

So now I'm going to say goodbye to all my friends, sell and donate all my belongings, and go back home with nothing but the same 2 suitcases I brought with me when I left São Paulo 4 years ago. Like many of my professors, grad students, and fellow scientists, I was a casualty of the STEM mass murder of 2025. Forgive me if I'm bitter and angsty for the next few weeks or even months. I hope you can understand. Thank you for reading, if you've made it this far.

Com muito amor e raiva,

Ryan

So my aunt seems to have witnessed BALL LIGHTNING and i can't get her to understand how potentially important that is

She's not a fantasist type, just a fun country gal in her 70s. So last night on the phone she casually drops that during a very intense thunderstorm a couple of nights ago, she sees lightning congeal into an orb and hover above the ground for a couple seconds before fizzling out, and she was scared of fire and for her neighbor's cows. She's just like 'Yeah it was scary :(, but anyway i saw your cousins :)' and i'm like AUNTIE, YOU ARE MORE LIKELY TO GET BIGFOOT'S AUTOGRAPH THAN SEE BA--

'Yeah i wish i had gotten it on video, haha but it was very scary' AUNTIE, IF YOU HAD GOTTEN IT ON VIDEO YOUR NAME WOULD BE IN HISTORY BOOKS

it's absolutely incredible that i can only find maybe 2 or 3 articles, only one from a mainstream news publication, about the recent findings from James Hansen - a world renowned climate scientist - regarding the death of the 2c of warming goal and the state of the climate in general. it's not a surprise, mind you. just incredible that we're really sleepwalking into all of this.

New research by an international team of climate scientists documents a surge of global warming during the past 15 years that risks shutting down a key ocean current by 2050.  During a webinar Tuesday discussing the study, the authors said the rate of global warming since 2010 has increased by more than 50 percent over the rate of warming in the preceding four decades, surging more than 0.7 degrees Fahrenheit (0.4 degrees Celsius) in just the past two years. At the current rate, the Paris Agreement goal of limiting global warming to somewhere between 2.7 degrees and 3.6 degrees Fahrenheit (1.5-2 degrees Celsius) is pretty much dead, said James Hansen, a former NASA climate scientist who led the team and whose 1988 testimony to Congress was one of the early public warnings about the risks of greenhouse gas emissions. The increased rate of warming will intensify already deadly heatwaves and worsen both drought and flooding extremes, as well as speed up the spread of deadly diseases associated with warmer temperatures.  The shutdown of the Atlantic Meridional Overturning Current (AMOC) discussed in the new paper would lead to a sudden surge of sea level rise along the East Coast, and bring crop-threatening climate extremes to parts of Europe, according to a 2024 study. Scientists expected the global average temperature to start dropping this winter because parts of the tropical Pacific Ocean are in La Niña conditions, the cool phase of a cycle that can reduce the annual global average temperature by up to 0.36 degrees Fahrenheit.  Instead, temperatures continued to surge into 2025 with the warmest January on record—3.13 degrees Fahrenheit (1.74 degrees Celsius) above the pre-industrial baseline. Researchers have noted how the sustained warmth is unexpected. 

on top of all of this... from Elliot Jacobson:

This is worth watching every day! Arctic sea-ice extent continues on its record low trajectory, with the latest data from February 8 showing extent 428,000 square kilometers below the previous record daily low and 1.41 million square kilometers below the 1991-2020 average. Yikes!

NIH slashes overhead payments for research, sparking outrage

In a Friday night move that quickly drew howls of protest from the U.S. biomedical research community, President Donald Trump’s administration today announced it is immediately reducing by at least half the so-called indirect cost payments that the National Institutes of Health (NIH) makes to universities, hospitals, and research institutes to help cover facilities and administrative costs.

A 15% indirect cost rate will now apply to all new and existing grants, NIH said in a memo from its Director’s office. Typically, about 30% of an average NIH grant to an institution is earmarked for indirect costs, according to NIH, but some universities get much higher rates. In 2023, NIH, the world’s largest funder of biomedical research, spent nearly $9 billion on indirect costs; the change would likely leave research institutions needing to find billions of dollars from other sources to support laboratories, students, and staff.

So this hasn't gotten much media play because it's so administrative and specific but it's like....really, really, really bad for the entire scientific research ecosystem in this country. I have friends who could lose their jobs, I could lose my job. It's possible that the pushback will halt this, but it now has academia in a REALLY bad position in which we could be forced to (for example) cut DEI programs in order to maintain appropriate funding levels.

A team of astronomers led by Michael Janssen (Radboud University, The Netherlands) has trained a neural network with millions of synthetic black hole data sets. Based on the network and data from the Event Horizon Telescope, they now predict, among other things, that the black hole at the center of our Milky Way is spinning at near top speed. The astronomers have published their results and methodology in three papers in the journal Astronomy & Astrophysics.
