Scientists develop technique to observe radiation damage over femtoseconds
Scientists have developed a technique to observe how radiation damages molecules over time-frames of just one quadrillionth of a second — or a femtosecond.

Neurological signals from the spinal cord surprise scientists
With a study of the network between nerve and muscle cells in turtles, researchers have gained new insight into the way in which movements are generated and maintained. In the long term, the new knowledge may have an impact on the treatment of, for example, ALS and spinal cord injuries.
Read moreInnovative candidate drug against malaria
A molecule once designed to cure the skin disease psoriasis appears to be particularly effective against malaria. The antimalarial properties were revealed thanks to one researcher's inspired hunch when the psoriasis drug discovery program came to a dead end. The candidate drug offers considerable potential for combating this infectious disease.

Mechanical engineers have created the first robotic fish proven to mimic the speed and movements of live yellowfin tuna.
Read moreGreen light given to fruit fly's color preference
Researchers have made two unexpected discoveries. First, they found that, given a choice, fruit flies are drawn to green light early in the morning and late in the afternoon, when they are most active, and to red, or dim light, in midday, when like many humans, they slow down to eat and perhaps take a siesta.
Read moreNew tool improves beekeepers' overwintering odds and bottom line
A new tool can predict the odds that honey bee colonies overwintered in cold storage will be large enough to rent for almond pollination in February. Identifying which colonies will not be worth spending dollars to overwinter can improve beekeepers' bottom line.
Read morePorcupinefish inspires sturdy superhydrophobic material
Nature has evolved a dazzling array of materials that help organisms thrive in diverse habitats. Sometimes, scientists can exploit these designs to develop useful materials with similar or completely new functions. Now, researchers have made a durable and flexible super-water-repelling material inspired by spiky porcupinefish skin.
Read moreUsing unconventional materials, like ice and eggshells, as scaffolds to grow tissues
Researchers explore recent efforts to use everyday materials like ice, paper, and spinach as tissue scaffolds. These unconventional materials, they argue, are more functional, more sustainable, and less expensive, as well as being available around the globe and applicable to many areas of biomedical research.
Read moreThese pink sea urchins have teeth that sharpen themselves
Sea urchins have five teeth, each held by a separate jaw in a circular arrangement at the center of their spiked, spherical bodies. Now, researchers have discovered how the teeth of the pink sea urchin are specially equipped to sharpen themselves.

New research shows large wine challenges tend to favor wines with high ethanol and sugar levels. Flavors often associated with sweetness, including exotic fruits in white wines and dried fruit and spiciness in reds, also increase the chances of winning top prizes.
