Scientists have figured out how our brains sharpen our memories while we sleep

We all know that if we want what we've studied during the day to stick, it's best to get a good night's sleep. And while scientists have long understood that our memories rely on connections being built between neurons in our brains, it's not been clear how sleep actually helps to consolidate that information.



Now, two new studies have found biological evidence that expains the age-old wisdom that if we want to remember, we need to sleep to forget.


Tardigrades: The Micro World Meets the Macro World

Tardigrades are some of the most resilient creates on our planet. They are able to survive extreme situations by going into a sort of hibernation. These beings offer hope for finding life on other (more desolate) worlds in our solar system.


First human-pig 'chimera' created in milestone study | Science

Scientists have created a human-pig hybrid in a milestone study that raises the prospect of being able to grow human organs inside animals for use in transplants.



It marks the first time that embryos combining two large, distantly-related species have been produced. The creation of this so-called chimera – named after the cross-species beast of Greek mythology – has been hailed as a significant first step towards generating human hearts, livers and kidneys from scratch.


New organisms have been formed using the first ever 6-letter genetic code

Scientists have engineered the first ever 'semi-synthetic' organisms, by breeding E. coli bacteria with an expanded, six-letter genetic code.



While every living thing on Earth is formed according to a DNA code made up of four bases (represented by the letters G, T, C and A), these modified E. coli carry an entirely new type of DNA, with two additional DNA bases, X and Y, nestled in their genetic code.


Scientists grew human fallopian tubes in the lab

Researchers in Germany have have grown the innermost layer of human fallopian tubes in a lab. The new technique is offering fresh insights into this essential component of the female reproductive system, while also hinting at potential new directions for the treatment of various reproductive disorders.

Research Shows Evolution in Real Time illustrating interaction between Ecology and Evolution

In a research to record the interaction of environment and evolution, led by University of California under Riverside biologist David Reznickhas has found new information illustrating the evolution of a population of guppies.

"We're detailing how evolution happens," Reznick, a professor of biology, said.


"Usually people look at evolution as change over time but they...
