Scientists use islands to gauge rainfall's effect on landscapes

If you've ever stood on a hill during a rainstorm, you've probably witnessed landscape evolution, at least on a small scale: rivulets of water streaming down a slope, cutting deeper trenches in the earth when the rain turns heavier.

Subconscious mental categories help brain sort through everyday experiences

Your brain knows it's time to cook when the stove is on, and the food and pots are out. When you rush away to calm a crying child, though, cooking is over and it's time to be a parent. Your brain processes and responds to these occurrences as distinct, unrelated events.

Spring cleaning in your brain: New stem cell research shows how important it is

Deep inside your brain, a legion of stem cells lies ready to turn into new brain and nerve cells whenever and wherever you need them most. While they wait, they keep themselves in a state of perpetual readiness – poised to become any type of nerve cell you might need as your cells age or get damaged.

Cardiopoietic 'smart' stem cells show promise in heart failure patients

Translating a Mayo Clinic stem-cell discovery, an international team has demonstrated that therapy with cardiopoietic (cardiogenically-instructed) or "smart" stem cells can improve heart health for people suffering from heart failure. This is the first application in patients of lineage-guided stem cells for targeted regeneration of a failing organ, paving the way to developmen

War on bugs: Research could lead to better bed bug control

As if trapped in a never-ending B movie about evil invaders, Cincinnatians have been tormented by a six-legged scourge for years. To the chagrin of many throughout the Queen City, this monster isn't an actor in a rubber alien costume; it's the real thing – Cimex lectularius, better known as the common bed bug.

Botanists in the rainforest: Chimpanzees use botanical skills to discover fruit

Fruit-eating animals are known to use their spatial memory to relocate fruit, yet, it is unclear how they manage to find fruit in the first place. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have now investigated which strategies chimpanzees in the Taï National Park in Côte d'Ivoire, West Africa, use in order to find fruit in the rain forest. The resu

Research reveals Rx target for HPV, Hep C and related cancers

New discoveries by a team of scientists at LSU Health Sciences Center New Orleans for the first time reveal the inner workings of a master regulator that controls functions as diverse as the ability of nerve cells to "rewire" themselves in response to external stimuli and the mechanism by which certain viruses hijack normal cellular processes to facilitate their replication that
