Long extinct squirrel-like creatures hold clues to earlier mammal evolution Mammals may have evolved much earlier than previously thought, according to researchers who’ve been studying the fossils of squirrel-like creatures that date back about 160 million years to the Triassic Period. The creatures have mammalian features and are from previously unknown species of haramiyid, which […]

If you have a bike, most surely you will own a helmet too. If you fall off the bike your helmet might avoid some nasty head injuries, right? That looks pretty obvious… except that it isn’t. Lets start with a little bit of skepticism, and as straightforward as it seems, we would like some proof […]

Coffee genome offers insights on why caffeine is produced Scientists have cracked the genome of Coffea canephora, one source of coffee beans, to gain insights into how caffeine evolved and why plants make it. A study published in Science details the complex evolution of caffeine in coffee and the ways in which that differs from […]

Spitzer detects proto-planetary collision near new star Evidence of a proto-planetary collision 1,200 light-years away has been seen near a young sun-like star by NASA’s Spitzer infrared space telescope. Scientists detected a significant change in the infrared radiation emissions from dust around the 35-million-year-old star, known as NGC 2547-ID8, in the constellation Vela. Discovery News […]

Ancient star holds evidence of one of its earliest ancestors Traces of one of the universe’s first stars may have been found in the chemical signature of another ancient star that gobbled up material from the earlier star’s supernova. SDS J0018-0939, a star found in the halo around the Milky Way about 1,000 light-years from […]

The last advances in genetics and genomics are leading a change in the paradigm about how to treat diseases. Epigenetics is the science field that studies how gene expression is regulated. Several modifications on the genes such as DNA-methylation, histone-acetylation or microRNA (miRNA) regulation are considered to be the main responsible in controlling gene expression […]

A switch for internal, external brain processes Researchers have observed how the brain switches between internal and external information processes in mice. Scientists manipulated thalamic reticular nucleus cells to get the mice to switch information systems. Researchers hope the study could lead to treatments for people with autism or schizophrenia, whose brains have difficulty with […]

Glowing sharks living in dark depths evolve special vision Some species of bioluminescent sharks that live in the darkest depths of the ocean have eyes that have evolved to detect complex patterns of light to communicate with each other, locate prey or hide themselves. Researchers found that the eyes of bioluminescent sharks provide better resolution […]

That the so-called “Mediterranean diet” is good to keep a healthy heart is well known. However, how the eating habits of this population help them to stay healthy is not fully understood yet. Researchers from the University of Cambridge in the UK have investigated the effect of lycopene , the substance that gives the red […]

Perhaps the most repeated words in the last few years when talking about graphene – since scientists Geim and Novoselov were awarded the Nobel Prize in Physics in 2010 for their groundbreaking experiments – are “the material of the future”. There are some risks regarding so many expectations about everything related to materials science, since […]
