Why hot water freezes faster than cold water

A team of researchers have defined a theoretical framework that could explain the Mpemba effect, a counterintuitive physical phenomenon revealed when hot water freezes faster than cold water, according to Science Daily.

The researchers, have confirmed how this phenomenon occurs in granular fluids, that is, those composed of particles that are very small and interact among those that lose part of their kinetic energy. Thanks to this theoretical characterization, "we can simulate on a computer and make analytical calculations to know how and when the Mpemba effect will occur," said Antonio Lasanta. "In fact," he said, "we find not only that the hottest can cool faster but also the opposite effect: the coldest can heat faster, which would be called the inverse Mpemba effect."

The birth of the cyborg brain: Groundbreaking implant boosts human memory for the first time

Scientists have developed a groundbreaking brain implant that can boost human memory.

In recent years, studies have shown that so-called ‘memory prostheses’ can be used to improve memory in rodents and primates, helping them to perform better on cognitive tasks according to Daily mail.

Discovery of gigantic 'planet' baffles astronomers

A massive new ‘planet’ has been discovered that is so large it may not actually be classed as a planet, according to astronomers.

The new discovery is called OGLE-2016-BLG-1190Lb and is thought to be more than 13 times bigger than Jupiter, our solar system’s largest planet. The Korea Astronomy and Space Science Institute announced the discovery in a paper published on arXiv.org, according to RT.

145 million-year-old fossils of tiny rat-like creatures are found on Dorset's Jurassic Coast

They walked the Jurassic Coast of Dorset around 145 million-years ago. 

Now scientists have discovered fossils of the oldest mammals related to mankind. 

Researchers have found two teeth from small, rat-like creatures that lived in the shadow of the dinosaurs, according to Daily Mail.

They are the earliest undisputed fossils of mammals belonging to the line that led to human beings.

Sheep have ability to recognise human faces

Ewe look familiar: sheep have a human-like ability to recognise faces

Sheep have demonstrated the ability to recognise familiar human faces, according to a study.

Cambridge University researchers were able to train sheep to identify the faces, according to BBC.

After training, the sheep chose photos of familiar faces over unfamiliar ones significantly more often than not.

It shows that sheep possess similar face recognition abilities to primates.
