Full offence but countries like America, Australia, the UK, etc, should all be -- not only accepting as many refugees from Afghanistan as need be, but helping refugees get the fuck out of Afghanistan.
We're the ones who spent twenty years fucking up their country and murdering their civilians "for fun." And then we just collectively drop everything and say "the Taliban can have you."
Fuck that noise. It's disgusting. There are untold numbers of people fleeing the Taliban right now, across the whole country, with all of them -- but especially women and anyone who might be accused of helping the old government/foreign armies -- fearing for their lives.
The Western countries that have spent two decades fucking up Afghanistan have a duty of fucking care to the civilians left behind.
Breaking news as of 16 August 2021 is that the Afghan president and all other government officials have fled Kabul. The "last stronghold" that was predicted to "hold out against the Taliban for three months" has fallen within a week, and most civilians in that city and others that have been overrun are now fearing for their lives.
We have a basic moral obligation to help them in any way possible. That includes taking unreserved numbers of refugees that are refugees in large part due to the actions of the "heroic west."

What鈥檚 Inside a 鈥楧ead鈥 Star?
Matter makes up all the stuff we can see in the universe, from pencils to people to planets. But there鈥檚 still a lot we don鈥檛 understand about it! For example: How does matter work when it鈥檚 about to become a black hole? We can鈥檛 learn anything about matter after it becomes a black hole, because it鈥檚 hidden behind the event horizon, the point of no return. So we turn to something we can study 鈥 the incredibly dense matter inside a neutron star, the leftover of an exploded massive star that wasn鈥檛 quite big enough to turn into a black hole.
Tumblr media
Our Neutron star Interior Composition Explorer, or NICER, is an X-ray telescope perched on the International Space Station. NICER was designed to study and measure the sizes and masses of neutron stars to help us learn more about what might be going on in their mysterious cores.
Tumblr media
When a star many times the mass of our Sun runs out of fuel, it collapses under its own weight and then bursts into a supernova. What鈥檚 left behind depends on the star鈥檚 initial mass. Heavier stars (around 25 times the Sun鈥檚 mass or more) leave behind black holes. Lighter ones (between about eight and 25 times the Sun鈥檚 mass) leave behind neutron stars.
Tumblr media
Neutron stars pack more mass than the Sun into a sphere about as wide as New York City鈥檚 Manhattan Island is long. Just one teaspoon of neutron star matter would weigh as much as Mount Everest, the highest mountain on Earth!
Tumblr media
These objects have a lot of cool physics going on. They can spin faster than blender blades, and they have powerful magnetic fields. In fact, neutron stars are the strongest magnets in the universe! The magnetic fields can rip particles off the star鈥檚 surface and then smack them down on another part of the star. The constant bombardment creates hot spots at the magnetic poles. When the star rotates, the hot spots swing in and out of our view like the beams of a lighthouse.
Tumblr media
Neutron stars are so dense that they warp nearby space-time, like a bowling ball resting on a trampoline. The warping effect is so strong that it can redirect light from the star鈥檚 far side into our view. This has the odd effect of making the star look bigger than it really is!
Tumblr media
NICER uses all the cool physics happening on and around neutron stars to learn more about what鈥檚 happening inside the star, where matter lingers on the threshold of becoming a black hole. (We should mention that NICER also studies black holes!)
Tumblr media
Scientists think neutron stars are layered a bit like a golf ball. At the surface, there鈥檚 a really thin (just a couple centimeters high) atmosphere of hydrogen or helium. In the outer core, atoms have broken down into their building blocks 鈥 protons, neutrons, and electrons 鈥 and the immense pressure has squished most of the protons and electrons together to form a sea of mostly neutrons.
But what鈥檚 going on in the inner core? Physicists have lots of theories. In some traditional models, scientists suggested the stars were neutrons all the way down. Others proposed that neutrons break down into their own building blocks, called quarks. And then some suggest that those quarks could recombine to form new types of particles that aren鈥檛 neutrons!
Tumblr media
NICER is helping us figure things out by measuring the sizes and masses of neutron stars. Scientists use those numbers to calculate the stars鈥 density, which tells us how squeezable matter is!
Let鈥檚 say you have what scientists think of as a typical neutron star, one weighing about 1.4 times the Sun鈥檚 mass. If you measure the size of the star, and it鈥檚 big, then that might mean it contains more whole neutrons. If instead it鈥檚 small, then that might mean the neutrons have broken down into quarks. The tinier pieces can be packed together more tightly.
Tumblr media
NICER has now measured the sizes of two neutron stars, called PSR J0030+0451 and PSR J0740+6620, or J0030 and J0740 for short.
J0030 is about 1.4 times the Sun鈥檚 mass and 16 miles across. (It also taught us that neutron star hot spots might not always be where we thought.) J0740 is about 2.1 times the Sun鈥檚 mass and is also about 16 miles across. So J0740 has about 50% more mass than J0030 but is about the same size! Which tells us that the matter in neutron stars is less squeezable than some scientists predicted. (Remember, some physicists suggest that the added mass would crush all the neutrons and make a smaller star.) And J0740鈥檚 mass and size together challenge models where the star is neutrons all the way down.
Tumblr media
So what鈥檚 in the heart of a neutron star? We鈥檙e still not sure. Scientists will have to use NICER鈥檚 observations to develop new models, perhaps where the cores of neutron stars contain a mix of both neutrons and weirder matter, like quarks. We鈥檒l have to keep measuring neutron stars to learn more!

UPDATE: The explosion in Beirut killed at least 25 people and wounded over 2,500, says Lebanon's health minister. Officials say all hospitals there are full. Casualties and injuries are expected to rise, with many believed buried under the rubble.
UPDATE: At least 10 people were killed by an explosion in Beirut, security officials told @reuters Lebanese security official announces that "explosive material" was stored in a warehouse in Beirut's port (a very heavily populated area). Israel has long accused Hezbollah of storing explosive weapons in downtown Beirut. At least 15 people killed and hundreds more injured.
The cause and total casualties are unknown
"Dozens" wounded, say officials
Witnesses report people hit by flying glass, debris

Get Ready to 'Catch These Hands!' in Newly Licensed Yuri Manga
On Friday, August 20, Yen Press announced that it has licensed Murata's Yuri manga Watashi no Kobushi wo Uketomete! and will be publishing it as Catch These Hands! The first volume of the manga will be available in English in February 2022.
Tumblr media
The manga follows Takebe, a former delinquent, who runs into her old high school rival, Soramori. The two fight for the first time in years and Soramori emerges victorious. Takebe is left with only one choice... to accept the victor's request to start dating her!? These two take their battles from back-alley brawls into long-term relationships in this comedy romance manga.
Catch These Hands! was serialized in Kadokawa's Young Ace Up from January 2018 till its conclusion in October 2020. Four volumes are published in Japanese by Kadokawa.
Tumblr media
Murata is known for their Love Live and BanG Dream! Yuri doujinshi, sometimes released under their circle name CURL UP.
You can check out Catch These Hands! when it debuts in English in February.
