The Future of Evolution: What Will We Become?

Could humans split into two species? Perhaps, if we engineer one or if a colony is isolated in outer space. Image credit: stockxpert

From Live Science:

Editor's Note: This is the last in a 10-part LiveScience series on the origin, evolution and future of the human species and the mysteries that remain to be solved.

The past of human evolution is more and more coming to light as scientists uncover a trove of fossils and genetic knowledge. But where might the future of human evolution go?

There are plenty of signs that humans are still evolving. However, whether humans develop along the lines portrayed by hackneyed science fiction is doubtful.

Vaccines On Horizon For AIDS, Alzheimer's

From Time Magazine:

(MARIETTA, Pa.) — Malaria. Tuberculosis. Alzheimer's disease. AIDS. Pandemic flu. Genital herpes. Urinary tract infections. Grass allergies. Traveler's diarrhea. You name it, the pharmaceutical industry is working on a vaccine to prevent it.

Many could be on the market in five years or less.

Contrast that with five years ago, when so many companies had abandoned the vaccine business that half the U.S. supply of flu shots was lost because of contamination at one of the two manufacturers left.

Interview: The Man Who Makes Killer Robots For The US Military


From CNET:

It sounds like the opening scene of a Terminator movie: a team of intelligent air, land and sea robots working together to hunt down a group of human soldiers. Detected by infrared sensors mounted on a cyber-jetski, the platoon is forced to take shelter in a beach bunker. Stealthy flying drones then co-ordinate an attack, flushing the panicked warriors right into the arms of a pair of tracked and armed ground robots. Game over, man.

Don't Pack Your Parachute: Totally Free Fall



From New Scientist:

ON A bright day in 1912, an Austrian tailor named Franz Reichelt jumped off the Eiffel Tower in Paris, France. This was no suicide attempt. Reichelt was wearing a special overcoat of his own design that was supposed to let him glide gently to the ground. Sadly, it didn't work. As the crowd watched and movie cameras whirred, the "flying tailor" plunged 60 metres to his death.

Top 10 Languages On The Internet

From Discovery News:

f the Internet is the new public square, it's crowded and noisy. More than 1.4 billion people gather and talk on its cyber sidewalks.

Despite all those tongues, it's not a very linguistically diverse place.

More than half are in three languages: English, Chinese and Spanish.

Compare that to the number of known languages, 6,912 according to Ethnologue.com, and residency in the online neighborhood seems wildly exclusive.

A Case In Antiquities For ‘Finders Keepers’

Viktor Koen

From New York Times:

Zahi Hawass regards the Rosetta Stone, like so much else, as stolen property languishing in exile. “We own that stone,” he told Al Jazeera, speaking as the secretary general of Egypt’s Supreme Council of Antiquities.

The British Museum does not agree — at least not yet. But never underestimate Dr. Hawass when it comes to this sort of custody dispute. He has prevailed so often in getting pieces returned to what he calls their “motherland” that museum curators are scrambling to appease him.

Attractiveness Based Partly on Skin Color

Participants in the study changed the skin color of the faces in images (right), making the skin redder, yellower and brighter (from top to bottom), saying those looked healthier than faces that are less red, less yellow and less bright (left).

From Live Science:

When it comes to an attractive face, color can make all the difference, suggests a new study.

The research focused on facial skin color among Caucasians, finding a light, yellowish complexion looks the healthiest. The skin color could indicate a healthy diet of fruits and vegetables, whose pigments are known to change the skin's hue, researchers suggest.

(The researchers predict the results would hold for other ethnicities as well.)

From The New Scientist:

Rising temperatures are causing some of the oldest trees on Earth to grow faster, new research suggests. But scientists are divided over whether or not the change will benefit the climate, as it may simply cause the trees to die more quickly.

Previous research (pdf) suggested that Great Basin bristlecone pines located in the mountains of western US are growing more rapidly. But the reason for the growth spurt – and whether or not it is unusual – was unclear.

Bacteria 'Glow Near Landmines'


From The Telegraph:

Bacteria that glow green in the presence of explosives could provide a cheap and safe way to find hidden landmines, according to British scientists.

The bugs can be mixed into a colourless solution that forms green patches when sprayed on to ground where mines are buried.

Researchers who created the bacteria at the University of Edinburgh believe the microbes could be dropped from the air on to danger areas.

Within a few hours, they would react to traces of explosives leaking from the devices buried underground.

Each year, between 15,000 and 20,000 people are killed or injured by landmines and unexploded ordnance, according to the charity Handicap International.

Fishing Quota Will Lead To Extinction Of Bluefin Tuna, Warn Conservationists


From Times Online:

Conservationists have accused the organisation charged with ensuring the survival of the bluefin tuna of pushing the fish to extinction.

Members of the International Convention for the Conservation of Atlantic Tuna (ICCAT) voted to allow 13,500 tonnes of tuna to be caught next year, which scientists say will lead to the disappearance of the fish from the Mediterranean within two years.

The European Union was blamed for having blocked plans at the Brazil conference for a moratorium on catching the fish in the Mediterranean.
