We summarize the week's scientific breakthroughs every Thursday.
- Animals
Sperm on a stick for springtails
Many males of the tiny soil organisms sustain their species by leaving drops of sperm glistening here and there in the landscape in case a female chooses to pick one up.
- Neuroscience
Caffeine’s little memory jolt garners a lot of excitement
A new study claims that caffeine can perk up memory consolidation in students without a caffeine habit. But concerns about the effect size and the statistics in the paper require a little extra shot of replication.
- Animals
Insect queens sterilize workers with similar chemical
When exposed to a form of saturated hydrocarbons that mimicked the queen’s scent, the worker insects’ ovaries degraded.
- Neuroscience
Thinking hard weighs heavy on the brain
A balance measures the tiny changes in force due to blood flow behind a person's thoughts.
- Plants
Plants’ ATP collector found
Scientists identified two genes that write the code for the molecules, or receptors, that pull ATP into plant cells.
- Animals
Jellyfish bloom in spring when winter ‘timer’ dings
The coordinated appearance of the adult form of the animal is the result of a metamorphosis hormone that accumulates during winter months.
- Animals
African vultures follow the dead, not the herd
Wildebeest may be numerous, but they’re not attractive to carrion-eating birds unless they’re about to die.
- Animals
Head cam shows how falcons track prey
Falcons use motion camouflage to capture flying prey, a new study shows.
- Genetics
Life at the Speed of Light
Biology has come a long way from the days of mixing things in petri dishes and hoping something interesting happens. In his new book, Venter introduces readers to a future of precise biological engineering.
- Animals
Swimming dolphins don’t need to cheat
Dolphins swimming through bubbles burst old notion of underpowered muscles.
- Life
V-flying birds pick efficient flapping pattern
Ibises time their flaps to catch a boost from a neighbor’s wing.
- Ecosystems
Trees’ growth keeps climbing with age
Older trees pack on weight faster, making them potentially the best carbon collectors.
