This Week: Scraps of ancient textiles found
In the News: Mass killings explained?
As high-tech giants buy patents and launch lawsuits. How does the patent system work? Why does it fail? What does it mean to be “new, non-obvious and useful”? What will be the impact of the new patent law — the biggest change in 60 years? Why should we care?
Sometimes, scientists feel the need to leave the lab and warn the public about onrushing hazards. Rowland warned about ozone, but others are warning about warming. Does scientific culture encourage or hinder going public? Does the helpful response to ozone depletion suggest we’ll succeed in confronting global warming?
Neutrinos are odd: Extremely difficult to see, they travel through mass with scarcely a trace. A 1-billion ton detector in South Pole ice is now counting neutrinos, intent on understanding their origin and role in the universe, and even spotting echoes of the Big Bang.
A crash course in “sink or swim” teaches computerized robots to adapt to changing circumstances. When taught by “directed evolution,” robots that started without legs learned to walk sooner than robots that started with legs! Can you explain?
Can pigeons learn an abstract mathematical rule? Apparently, according to a new study, which asked pigeons to place, five blue dots and eight green squares, in ascending order. Now we know birds and primates can both do this, but where and why did this ability originate?
Scientists thought wings were the first evidence of flight. But plenty of falling ants can glide back to “their” tree to avoid being devoured on the forest floor. If an ant’s brain and body are able to detect its position and change its flight path, is gliding the first flight?
Seismic study shows crust thinning as continent divides, giving another view of our restless planet, showing tectonic movement in action, and highlighting a major real-estate investment opportunity.
If conflicts are more common near the equator, what will global warming affect do? A new study shows increases in conflict during el Niño periods — but only during the warm, dry part of the cycle, and only in places affected by these big climatic cycles.
Hitting the road? What could be more enlightening than gawking at a cave, exploring a desert, or eyeballing the largest telescope in the world? Need proof that science is not just books and websites or equations and software? Get moving!
