While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage. A group of scientists has investigated this less-studied idea, carrying out the first systematic computational analysis to identify long-established genes that have been lost across millions of years of evolution leading to the human species. picked by AutumnLotus 2 years ago

Science fiction writers have suggested a future Earth populated by a blend of all races into a common human form. In real life, the reverse seems to be happening. picked by Mershaullk 2 years ago

The Human Genome Project revealed that only a small fraction of the 3 billion “letter” DNA code actually instructs cells to manufacture proteins, the workhorses of most life processes. This has raised the question of what the remaining part of the human genome does. How much of the rest performs other biological functions, and how much is merely residue of prior genetic events?

T'S a question at the heart of what it is to be human: why do we go to war? The cost to human society is enormous, yet for all our intellectual development, we continue to wage war well into the 21st century. picked by bingo 1 year ago

A new study has concluded that one key part of the immune system, the ability of vitamin D to regulate anti-bactericidal proteins, is so important that is has been conserved through almost 60 million years of evolution and is shared only by primates, including humans – but no other known animal species. picked by Bingo 3 months ago

Artificial wombs and experiments on human embryos grown in the lab will be commonplace and no big deal ethically in 30 years, several scientists predict. They envision a scenario just like test-tube babies, which shocked us 30 years ago but now are fairly routine and acceptable to most people. picked by deEPCHIll 1 year ago

For the first time in the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo. This means it might be possible in the future to produce hESC lines at an earlier stage without destroying the embryo. picked by AutumnLotus 1 year ago

French fossil hunters have pinned down the age of Toumai, which they contend is the remains of the earliest human ever found, at between 6.8 and 7.2 million years old. The fossil was discovered in the Chadian desert in 2001 and an intense debate ensued over whether the nearly complete cranium, pieces of jawbone and teeth belonged to one of our earliest ancestors. picked by AutumnLotus 2 years ago
