- Colorful caterpillar chemists
- Signs of ancient mega-tsunami could portend modern hazard
- An accessible approach to making a mini-brain
| Posted: 02 Oct 2015 11:49 AM PDT Scientists have compared the diets of two caterpillar species, expecting the one that exclusively consumed plants containing toxic chemicals would more easily incorporate toxins into its body than the one with a broad diet. They found the opposite. The new finding flies in the face of a long-held theory that specialist insects are better adapted to use toxic plant chemicals than non-specialists. |
| Signs of ancient mega-tsunami could portend modern hazard Posted: 02 Oct 2015 11:49 AM PDT Scientists working off west Africa in the Cape Verde Islands have found evidence that the sudden collapse of a volcano there tens of thousands of years ago generated an ocean tsunami that dwarfed anything ever seen by humans. The researchers say an 800-foot wave engulfed an island more than 30 miles away. The study could revive a simmering controversy over whether sudden giant collapses present a realistic hazard today around volcanic islands, or even along more distant continental coasts. |
| An accessible approach to making a mini-brain Posted: 01 Oct 2015 06:38 AM PDT In a new paper, researchers describe a relatively accessible method for making a working -- though not thinking -- sphere of central nervous system tissue. The advance could provide an inexpensive and easy-to-make 3-D testbed for biomedical research. |
