In the 'neck' of time: Scientists unravel another key evolutionary trait

By deciphering the genetics in humans and fish, scientists now believe that the neck -- that little body part between your head and shoulders -- gave humans so much freedom of movement that it played a surprising and major role in the evolution of the human brain, according to neuroscientists.
Engineered coral pigment helps scientists to observe protein movement

Scientists have shown that a variant form of a fluorescent protein originally isolated from a reef coral has excellent properties as a marker protein for super-resolution microscopy in live cells.
Shared phosphoproteome links remote plant species

Researchers have shown that even the most widely-varying species of plants share remarkable similarities in the composition of proteins in them that undergo phosphorylation, a regulatory mechanism involved in various cellular phenomena. A database released by the group, with information on over three thousand phosphorylated proteins and phosphorylation sites in rice, opens new doors in the study and engineering of plants.
Urine: Waste product or future power source?

Researchers in the UK are looking into the use of urine as the ‘fuel’ for microbial fuel cells (MFCs), which use bacterial cultures to break down ‘food’ to create power. MFCs are a developing technology used to power autonomous robots.
Segmentation is the secret behind the extraordinary diversification of animals

Segmentation, the repetition of identical anatomical units, seems to be the secret behind the diversity and longevity of the largest and most common animal groups on Earth. Researchers have shown that this characteristic was inherited from a common segmented ancestor thought to have lived 600 million years ago and whose presence "changed the face of the world."
Scientists test Australia's Moreton Bay as coral 'lifeboat'

An international team of scientists has been exploring Australia's Moreton Bay, close to Brisbane, as a possible 'lifeboat' to save corals from the Great Barrier Reef at risk of extermination under climate change. In a new research paper, they say that corals have been able to survive and flourish in the Bay, which lies well to the south of the main GBR coral zones, during about half of the past 7000 years.

You are young, my son, and, as the years go by, time will change and even reverse many of your present opinions. Refrain therefore awhile from setting yourself up as a judge of the highest matters.
There is no law of progress. Our future is in our own hands, to make or to mar. It will be an uphill fight to the end, and would we have it otherwise? Let no one suppose that evolution will ever exempt us from struggles. 'You forget,' said the Devil, with
Man must evolve for all human conflict a method which rejects revenge, aggression and retaliation. The foundation of such a method is love.
