A new paper published in Nature Communications could put scientists on the path to understanding one of the wildest, hottest, and most densely packed places in the universe: a neutron star.

Eight ways to resist spending too much on Black Friday bargains

phys.org

It is that time of the year again—Black Friday is almost upon us. What used to be just an American event has now taken over the calendar in many other countries as one of the key shopping events of the year.

The surprising world of animal penises and what they reveal about humans

phys.org

In the animal kingdom, penises can be spiked, split, corkscrewed—even detachable. They're one of the most diverse structures in biology. The human penis is so uniform, it's an anatomical outlier. Understanding why penises evolved, and why…

Advanced tracking uncovers flapper skate hotspots on Scotland's deep seabed

phys.org

Flapper skate (Dipturus intermedius), the world's largest skate species measuring over two meters in length, live hidden on the rugged seabed around Scotland. Their life in the darkness, deep underwater, makes it extremely difficult to…

Studies show how the giant statues on Rapa Nui were made and moved—and what caused the island's deforestation

phys.org

Rapa Nui, also known as Easter Island, is often portrayed in popular culture as an enigma. The rationale is clear: The tiny, remote island in the Pacific features nearly 1,000 enormous statues—the moai. The magnitude and number of these…

'Stick and glue' method enables more precise biomolecule tracking in cells

phys.org

A team of researchers at IOCB Prague headed by Dr. Tomáš Slanina has developed a new method for labeling molecules with fluorescent dyes that surpasses existing approaches in both precision and stability. The new fluorescent label remains…

Domestic cats came from North Africa to Europe only 2,000 years ago, DNA evidence suggests
