We summarize the week's scientific breakthroughs every Thursday.
- Tech
Hopping robot powered by explosions
A soft-bodied robot that can jump with the help of an explosion could one day aid search-and-rescue operations.
- Tech
Long after JFK assassination, gunshot forensics still limited
The Warren Commission Report included the results of a neutron activation analysis test of Lee Harvey Oswald. But even that high-tech analysis can't distinguish the type of weapon fired.
- Tech
Octobot uses webbed arms to swim faster
Octopus-inspired robot could one day help researchers observe underwater ecosystems.
- Tech
Hydrogen made using sunlight, cheap materials
Photosynthesis-inspired fuel cell uses water to make hydrogen gas and could feature in next-generation cars.
- Planetary Science
Spot on comet chosen for Rosetta mission lander
Philae, the Rosetta mission lander, will attempt to land on a spot called site J on comet 67P/Churyumov–Gerasimenko.
- Tech
‘Virtual Unreality’ chronicles dangers of digital deception
Journalist Charles Seife documents how the lies and misinformation that riddle the Internet are harming the real world.
- Tech
Space tourism’s price tag rockets upward
The “high price” of space tourism proposed in the 1960s is nowhere close to the astronomical price tag of trips today.
- Tech
To have a sound mind, a brain needs a body
Replicating human intelligence in robots requires the right materials for brain-body-environment interactions.
- Tech
Robot swarm takes many shapes
One Kilobot is not very smart. But 1,000 can follow simple instructions to assemble into multiple shapes without human intervention.
- Materials Science
Magnets get flipped by light
Controlling magnetism with lasers could lead to faster computer hard drives.
- Life
Malaria parasite’s invasion of blood cells tweezed apart
Tugging on malaria-causing parasite cells with laser optical tweezers suggest that the parasite cells interact only weakly with red blood cells and that the interactions could be disrupted with drugs or antibodies.
- Computing
Thousand-robot swarm self-assembles into complex shapes
A swarm of a thousand tiny robots can now self-assemble into complex shapes, suggesting scientists have taken a step forward in engineering collective artificial intelligence
