Researchers discover why killer whales go through menopause

Researchers discover why killer whales go through menopause

A new study by an international team of researchers has suggested that conflicts between mother and daughter killer whales may elucidate why the females of the species go through menopause.

The researchers sifted through more than forty years of data on killer whales in the northwest Pacific, and found that younger females are more likely to reproduce than their older counterparts.

They discovered that the trend discourages mother killer whales from reproduction, making them more focused on raising their younger members of their families instead.

Researchers discover human-like vowel sounds in baboons’ calls

Researchers discover human-like vowel sounds in baboons’ calls

The origin of human speech could reach back as many as 25 million years as researchers have discovered distinct human-like vowel sounds in the grunts and mating calls of non-human primates Guinea baboons.

Led by Grenoble Alpes University’s Dr. Louis-Jean Boe, a team of experts studied the acoustics of a total of 1,335 baboon sounds as well as the animals’ tongue anatomy.

Physicists successfully cool microscopic drum below quantum limit

Physicists successfully cool microscopic drum below quantum limit

A team of physicists at the National Institute of Standards & Technology (NIST) claimed to have cooled a microscopic mechanical drum, a vibrating aluminum membrane, to a temperature lower than what formerly was thought possible, below the “quantum limit.”

The researchers showed that the ‘absolute zero’ is not just cold, it is only still because at this point the motion of the atoms or the building blocks of an object stops completely, and the object is left with no energy to give.

Researchers find new way to spin artificial spider silk

Researchers find new way to spin artificial spider silk

Scientists have long been trying to artificially create spider silk as this miracle material could pave the way to create super-strong, durable fabrics. Moving a step closer to the crazy durable fabrics, a team of researchers claimed to have designed a machine that can really spin something almost as good spider silk fiber.
