'Fool's gold' may be valuable after all

In a breakthrough new study, scientists and engineers have electrically transformed the abundant and low-cost non-magnetic material iron sulfide, also known as 'fool's gold' or pyrite, into a magnetic material.

New set of channels connecting malaria parasite and blood cells

Researchers have discovered another set of pore-like holes, or channels, traversing the membrane-bound sac that encloses the deadliest malaria parasite as it infects red blood cells. The channels enable the transport of lipids -- fat-like molecules -- between the blood cell and parasite, Plasmodium falciparum. The parasite draws lipids from the cell to sustain its growth and may also secrete other...

Increasing Arctic freshwater is driven by climate change

Climate change is driving increasing amounts of freshwater into the Arctic Ocean. Within the next few decades, this will lead to increased freshwater moving into the North Atlantic Ocean, which could disrupt ocean currents and affect temperatures in northern Europe.

Underwater robots reveal daily habits of endangered whales

Research has revealed the daily habits of the endangered Mediterranean sperm whale. The recordings confirmed the whales' widespread presence in the north-western Mediterranean Sea and identified a possible hotspot for sperm whale habitat in the Gulf of Lion, as well as different foraging strategies between different areas.

New drug targets for lethal brain cancer discovered

More than 200 genes with novel and known roles in glioblastoma - the most aggressive type of brain cancer - offer promising new drug targets. Researchers engineered a new mouse model to show for the first time how a mutation in the well-known cancer gene, EGFR initiates glioblastoma, and works with a selection from more than 200 other genes to drive the cancer.

How a crystalline sponge sheds water molecules

How does water leave a sponge? In a new study, scientists answer this question in detail for a porous, crystalline material made from metal and organic building blocks -- specifically, cobalt(II) sulfate heptahydrate, 5-aminoisophthalic acid and 4,4'-bipyridine. Using advanced techniques, researchers studied how this crystalline sponge changed shape as it went from a hydrated state to a...

New fabric could help keep you cool in the summer, even without A/C

Air conditioning and other space cooling methods account for about 10% of all electricity consumption in the U.S., according to the U.S. Energy Information Administration. Now, researchers have developed a material that cools the wearer without using any electricity. The fabric transfers heat, allows moisture to evaporate from the skin and repels water.

Healing an Achilles' heel of quantum entanglement

Researchers have solved a 20-year-old problem in quantum information theory on how to calculate entanglement cost -- a way to measure entanglement -- in a manner that's efficiently computable, useful, and broadly applicable in several quantum research areas.

Transforming e-waste into a strong, protective coating for metal

A typical recycling process converts large quantities of items made of a single material into more of the same. However, this approach isn't feasible for old electronic devices, or ''e-waste,'' because they contain small amounts of many different materials that cannot be readily separated. Now researchers report a selective, small-scale microrecycling strategy, which they use to convert old...
