Drug that creates a 'real sun-tan' could prevent cancer

Scientists have developed a drug that mimics sunlight to make the skin tan, with no damaging UV radiation involved.

The drug tricks the skin into producing the brown form of the pigment melanin in tests on skin samples and mice, according to BBC.

Evidence suggests it will work even on redheads, who normally just burn in the sun.

Genes Influence Ability to Read Persons' Minds from Their Eyes

Our DNA influences our ability to read a person's thoughts and emotions from looking at their eyes, suggests a new study.

Twenty years ago, a team of scientists developed a test of 'cognitive empathy' called the 'Reading the Mind in the Eyes' Test (or the Eyes Test, for short). This revealed that people can rapidly interpret what another person is thinking or feeling from looking at their eyes alone. It also showed that some of us are better at this than others, and that women on average score better on this test than men.

Planet is 'hotter than most stars'

Scientists have found a hellish world where the "surface" of the planet is over 4,000C - almost as hot as our Sun.

In part, that’s because KELT-9b’s host star is itself very hot, but also because this alien world resides so close to the furnace, according to BBC.

KELT-9b takes just two days to complete one orbit of the star.

Breakthrough in the Search for Life on Mars as Curiosity Finds Layered Lake

Observations collected by NASA’s Curiosity rover over 3.5 years have revealed that oxygen levels in an ancient Martian lake differed between shallow and deep water.

And, researchers say this phenomenon is also common in lakes on Earth.

The discovery is a step toward better understanding whether Mars was ever able to support life, as this type of environment could have created ‘multiple opportunities for different types of microbes to survive.’

How dinosaurs may have evolved into birds

Evolutionary biologists have suspected that anatomical differences within and between species are caused by cis-regulatory elements (CREs). CREs are regions of genome DNA that do not code for proteins, and control morphology and other traits by regulating genes. According to Science daily

The international group of researchers analyzed the genomes of 48 avian species that represent the evolutionary history of modern birds and compared them to many other vertebrates to find DNA sequences specific to avians.
