Killing time: Study sheds light on phages and precision cell destruction

Phage therapy, which exploits the ability of certain viruses to infect and replicate within bacteria, shows promise for treating antibiotic-resistant bacterial infections. But designing such therapies depends on understanding how phages work. Phages can kill the cell immediately, or become dormant and kill it later, with a high level of precision in kill time.

Researchers identify monarch butterfly birthplaces to help conserve species

Researchers have pinpointed the North American birthplaces of migratory monarch butterflies that overwinter in Mexico, vital information that will help conserve the dwindling species. The researchers analyzed 'chemical fingerprints' in the wings of butterflies collected as far back as the mid-1970s to learn where monarchs migrate within North America each autumn.

Dual-purpose biofuel crops could extend production, increase profits

Dual-purpose biofuel crops could extend production by two months, decreasing the cost of each gallon of fuel and increasing profits by as much as 30 percent.

Surf and Earth: How prawn shopping bags could save the planet

Bioengineers are trialing how to use shrimp shells to make biodegradable shopping bags, as a ‘green’ alternative to oil-based plastic, and as a new food packaging material to extend product shelf life.

Summer heat for the winter

Can thermal solar energy be stored until wintertime? Within a European research consortium, scientists have spent four years studying this question by pitting three different techniques against each other.

Warmer West Coast ocean conditions linked to increased risk of toxic shellfish

Hazardous levels of domoic acid, a natural toxin that accumulates in shellfish, have been linked to warmer ocean conditions in waters off Oregon and Washington for the first time, report scientists.

New findings detail structure of immature Zika virus

Researchers have determined the high-resolution structure of immature Zika virus, a step toward better understanding how the virus infects host cells and spreads.

Secret new weapon of insect-transmitted viruses exposed

Findings by a team of scientists could provide critical knowledge to attack deadly viruses transmitted by arthropods such as mosquitoes and aphids.

Massive genetic study of humpback whales to inform conservation assessments

Scientists have published one of the largest genetic studies ever conducted on the humpback whale (Megaptera novaeangliae) for the purpose of clarifying management decisions in the Southern Hemisphere and supporting calls to protect unique and threatened populations, according to experts.

Bio-inspired suction cups withstand more than splashes

To create prototype suction cups that are capable of glomming onto rough, wet surfaces and staying there, a research team has found inspiration in an aptly-named marine creature: the clingfish.
