One of science's strongest dogmas is that complex life on Earth could only evolve when oxygen levels in the atmosphere rose to close to modern levels. But now studies of a small sea sponge fished out of a Danish Fjord shows that complex life does not need high levels of oxygen in order to live and grow.

Racism as a social and scientific concept is reshaped and reborn periodically through the ages and according to a Penn State University anthropologist, both medical and scientific researchers need to be careful that the growth of genomics does not bring about another resurgence of scientific racism.

Researchers from Warwick Medical School have discovered the key role of a protein in shutting down endocytosis during mitosis, answering a question that has evaded scientists for half a century.

It is well known that genes are passed from one generation to the next. In addition, new genes arise regularly, although the number of genes in a particular organism does not seem to increase. The paradox has been solved by recent research at the University of Veterinary Medicine, Vienna, which shows that newly created genes are frequently lost. The spontaneous appearance and disappearance of genes enables organisms to adapt rapidly to their environment and helps drive evolution. The work is published today in the journal eLife.

Some people recall a dream every morning, whereas others rarely recall one. A team led by Perrine Ruby, an Inserm Research Fellow at the Lyon Neuroscience Research Center (Inserm/CNRS/Université Claude Bernard Lyon 1), has studied the brain activity of these two types of dreamers in order to understand the differences between them. In a study published in the journal Neuropsychopharmacology, the researchers show that the temporo-parietal junction, an information-processing hub in the brain, is more active in high dream recallers. Increased activity in this brain region might facilitate attention orienting toward external stimuli and promote intrasleep wakefulness, thereby facilitating the encoding of dreams in memory.

Work reveals how a genome-editing tool works to correct errors in the genetic code.

With a nod to 3rd century Chinese woodblock printing and children's rubber stamp toys, researchers in Houston have developed a way to print living cells onto any surface, in virtually any shape. Unlike recent, similar work using inkjet printing approaches, almost all cells survive the process, scientists report in this week's Proceedings of the National Academy of Sciences.

Collaborative research center will bridge genomics and stem cell projects to find new therapies.

Neuroscience medical researchers can benefit from free online conferences and earn free continuing medical education (CME) credits.
