The most massive neutron stars probably have cores of quark matter

Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons have 2 ups and 1 down, while neutrons have 2 downs and 1 up. Because of the curious nature of the...

Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons have 2 ups and 1 down, while neutrons have 2 downs and 1 up. Because of the curious nature of the strong force, these quarks are always bound to each other, so they can never be truly free particles like electrons, at least in the vacuum of empty space. But a new study in Nature Communications finds that they can liberate themselves within the hearts of neutron stars.

Where is the center of the universe (where the Big Bang occurred) and where is its edge?

As counterintuitive as it may seem, the universe has no center, and it has no boundary.

The idea of a Big Bang acting like a giant fireworks explosion hurtling matter and energy outward is pervasive, but misleading. As bizarre as it sounds, it wasn't "stuff" that exploded outward, it was space itself! In essence, the Big Bang happened everywhere. Since the time of Einstein, it has been known that space is not simply a backdrop in which we move, but an actual thing that can be measured. It has shape, it can be bent, and it can expand.

Just two northern white rhinos are left on Earth. A new breakthrough offers hope

For the first time ever, a rhino was impregnated via in vitro fertilization. Scientists now believe they can use IVF to save the critically endangered northern white rhino.

Scientists and conservationists are hoping that IVF can be used to save another rhino subspecies: the northern white rhino, which is critically endangered because of poachers who hunted them for their horns.
Only two northern white rhinos remain on the planet, and both of them are female. The last male, Sudan, died in 2018.

Puerto Rican Crested Anoles are a prime example of adaptation in action. In just a few decades, these city-dwelling lizards have undergone remarkable evolutionary changes to thrive in an urban landscape. Longer limbs, stickier toe pads, and higher heat tolerance are just a few of the adaptations they've developed. Step into the captivating world of urban lizard discoveries with Shane Campbell-Staton and anole enthusiast, Kristin Winchell. Join us on a journey into the heart of Puerto Rico to witness the transformation of anoles, and understand what it means for their survival in our human-altered world.

Seems to be growing evidence that humans were in the Americas long before it was previously thought.
