Chemistry
We summarize the week's scientific breakthroughs every Thursday.
- Chemistry
Lasers wrest oxygen from carbon dioxide
By zapping oxygen molecules off carbon dioxide, an experiment hints that Earth may have had breathable air long before the dawn of plants.
- Chemistry
Interstellar chemical resembles building blocks of life
A molecule detected in the space between stars resembles amino acids, suggesting those building blocks of life share a similar origin.
- Tech
Solar cell powers water-to-hydrogen conversion
High efficiency could make perovskite solar cells useful for generating environmentally friendly fuel.
- 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
Moon’s farside hints at violent volcanic explosions
The spread of the element thorium in the moon's Compton-Belkovich region suggests that silica volcanoes there once had violent explosions.
- Materials Science
Buckyballs, diamonds inspire new synthetic molecule
Hitching a hollow ball of carbon to a diamond-shaped lattice yields a useful piece of electrical circuitry.
- Chemistry
Liquid salts break through armored bacteria on skin
Compounds called ionic liquids can penetrate bacterial biofilms on skin to deliver antibiotics to potentially life-threatening infections.
- Anthropology
Richard III ate like a king before biting the dust
King Richard III’s brief reign included a sudden shift to eating fancy food and drink.
- Chemistry
Molecular cage traps rare gases
Organic compound could cull valuable xenon from the air and detect cancer-causing radon in homes.
- Chemistry
Boron atoms take on buckyball shape
The first boron buckyball-like molecule could be used for storing hydrogen, scientists suggest.
- Animals
Mysterious neurotoxin may help flatworms kill prey
Tetrodotoxin, the deadly chemical in pufferfish, could help flatworms transform their earthworm prey into puddles of goo.
- Chemistry
Safe salt could yield cheaper, more efficient solar cells
Magnesium chloride could be the key ingredient for concocting efficient solar cells with cadmium telluride.
