Green sea slugs aren’t solar powered after all
Several species of sea slugs hold on to algal chloroplasts, digesting them weeks or months later. Scientists assumed the creatures were able to use these chloroplasts to make their own food in lean times. A new study finds that at least two of the species aren't solar powered after all.
- Genetics
Ancient Siberian bones clarify Native American origins
Some New World ancestors came from western Eurasia, not East Asia.

Comb jelly immune system can spot old enemies
Animal at base of family tree could help researchers understand the evolution of immunity.

Blood clotting disorder blocked in dogs
Gene therapy stopped severe bleeding in dogs with the blood clotting disorder hemophilia.
- Genetics
Sexy male mice have competitive moms
Moms allowed to compete for mates produce sons that make sexy pheromones, live hard and die young. How? Epigenetics.
- Ecosystems
Virus-blocking insects taking over Vietnamese island
Field trial tests mosquitoes that may stop the spread of dengue infection.
- Health & Medicine
Cage temps change tumor growth in mice
Cooler living conditions may influence lab mice's responses to experimental cancer therapies that target the immune system.
- Animals
Mothballs, rubbing alcohol score poorly in tests of DIY bedbug control
Mattress encasement, dry ice in bags, hot clothes dryers do help control infestation.

Migration is a deadly time for raptors
For a bird or any other animal that migrates a long distance, it’s sure to face a host of dangers. The story is no different for raptors.

Thank insects and microbes that we aren’t over our knees in feces
Ever wondered why you’re not drowning in poop? Scientists harnessed the power of citizen science to find the beetles and microbes we can thank for that.
- Humans
Humans’ music and genes may have evolved together
Music may be a tool scientists can use to trace human migrations.
