We summarize the week's scientific breakthroughs every Thursday.
- Neuroscience
Faulty brain wiring may contribute to dyslexia
Adults with the disorder showed difficulty transmitting information among areas that process language.
- Life
Autism may have link to chemicals made by gut microbes
Beneficial bacteria improved abnormal behaviors in mice with altered intestines.
- Life
Targeting single set of nerve cells may block mosquitoes
The insects use the same neurons to detect carbon dioxide from our breath and odors from our skin so blocking those cells could lead to more simplified repellent systems.

Male contraceptive test targets sperm’s travel route
Most efforts at a male contraceptive have focused on hormones, trying to stop production of sperm. A new study in mice explores leaving the sperm to themselves, and instead stops their transport.
- Neuroscience
Excess activity shrinks blood vessels in baby mouse brains
Newborn mouse pups experience permanent brain changes when repeatedly overstimulated.
- Animals
How the ghost shark lost its stomach
The lack of a digestive organ in fish and other animals is linked to genetics.
- Genetics
Evolution of venom, binge eating seen in snake DNA
Python and cobra genes evolved quickly to enable hunting strategies.

- Neuroscience
Fear can be inherited
Parents’ and even grandparents’ experiences echo in offspring, a study of mice finds.
- Neuroscience
Global neuro lab
With more than 50 million users, the brain-training website Lumosity is giving scientists access to an enormous collection of cognitive performance data. Mining the dataset could be the first step toward a new kind of neuroscience.
- Animals
DNA study reveals new wild cat species in Brazil
A new small cat species, Leopardus guttulus, was discovered in Brazil, hiding in plain sight. The oncilla, researchers say, is really two kinds of cat.

To cook up life, just add citrate
The theory that RNA spawned the first organisms gets a boost from a common compound.
