An international team of scientists report in the journal Genome Biology results from a pilot project, co-led by Robert Waterhouse, Group Leader at the SIB Swiss Institute of Bioinformatics and University of Lausanne, to kick-start the global sequencing initiative of thousands of arthropods.
The ancient-genomics revolution is finally reaching the cradle of humanity: Africa. Researchers have sequenced the genomes of four children who lived in what is now Cameroon several thousand years ago.Their genomes — the first to be collected from any ancient human in West Africa — raise questions about the origins of a migration that carried languages and agriculture across the continent, and hint at older events in human history, such as the emergence of Homo sapiens and its spread out of Africa.
Rob Sheldon: On the whole, Darwinism looks like it makes short-term gains at the cost of long-term stagnation. It clearly sacrifices the group for the sake of a few aggressive individuals.
A Dutch computer scientist and philosopher who has reflected deeply on the mind–matter problem finds himself asking, how can serious scientists or philosophers convince themselves that their own consciousness “doesn’t exist” or is a “mistaken construct”? What, exactly, is thinking the thought that
A bizarre tentacled microbe discovered on the floor of the Pacific Ocean may help explain the origins of complex life on this planet and solve one of the deepest mysteries in biology, scientists reported on Wednesday.Two billion years ago, simple cells gave rise to far more complex cells. Biologists have struggled for decades to learn how it happened.
Scientists have synthetically engineered mosquitoes that halt the transmission of the dengue virus. Biologists developed a human antibody for dengue suppression in Aedes aegypti mosquitoes, the insects that spread dengue. The development marks the first engineered approach in mosquitoes that targets the four known types of dengue, improving upon previous designs that addressed single strains.
Looking past the tabloid prose, they say they found that selection can occur at the level of the epigenome. So what becomes of neo-Darwinism if selection isn’t tied to the all-powerful but accidental gene?
