Cone Snails – Danger and Deception Wrapped in Beautiful Packages
- Cone snails, which are predatory molluscs, employ three main hunting strategies using deadly toxins.
Cone Snails – Venoms Have Unexpected Benefits
- Scientists are examining components of cone shell venom to develop a faster acting form of insulin and drugs to relieve severe chronic pain.
Hidden Health Concerns in Our Food and Water
- Scientists are examining possible health risks of Bisphenol A (BPA), a synthetic organic chemical long used in a variety of consumer goods.
Plants That Sting
- The chemistry of stinging plants from Australia has been analyzed, in part, to better understand pain stimulation and treatment, as well as feature evolution.
Seeding Cartilage Growth
- Scientists have stimulated skeletal stem cells to regrow cartilage in mice. Such work may lead to a safe and effective treatment for arthritis.

I. Preliminary Information Unit

Are Linden Trees Killing Bumblebees?
- Through observations and analysis, scientists have modified their hypotheses on factors leading to massive deaths of bumblebees under linden trees.
Cone Snails – Chemical Hackers
- Some cone snails can use as a hunting tool a chemical that mimics the pheromones of bristle worms to lure the worms out of seclusion.
Cone Snails – Venoms Have Unexpected Benefits
- Scientists are examining components of cone shell venom to develop a faster acting form of insulin and drugs to relieve severe chronic pain.
Electric Bacteria
- The presence of the cable bacteria can reduce methane release in flooded rice fields by over 90%. Could this be a significant weapon to reduce methane emissions into the atmosphere?
