Robotic Insect Mimics Nature’s Extreme Moves

August 3, 2015 | by Harvard University | Comments

Emulating the natural form of water-based locomotion, an international team of scientists has unveiled a novel robotic insect that can jump off of water’s surface. In doing so, they have revealed new insights into the natural mechanics that allow water striders to jump from ground or water with the same amount of power and height.

New Hope in Old Viruses

August 3, 2015 10:08 am | by Harvard University | Comments

Researchers have reconstructed an ancient virus that is highly effective at delivering gene therapies to the liver, muscle, and retina. The discovery, published in Cell Reports, has the potential to advance gene therapies that are not only safer and more potent than available therapies, but also to help a greater number of patients.

Researchers Discover Immune System’s 'Trojan Horse'

July 31, 2015 9:18 am | by University of Oxford | Comments

Researchers have found that human cells use viruses as Trojan horses, transporting a messenger that encourages the immune system to fight the very virus that carries it. The discovery could have implications for the design of new vaccines.

Delirium and Inflammation

July 30, 2015 10:25 am | by Harvard University | Comments

Delirium, an acute state of confusion, often affects older adults following surgery or serious illness. Now, a study confirms that inflammation—an immune response that develops when the body attempts to protect itself from harmful stimuli—plays a role in the onset of delirium.

Expanding the Brain

July 30, 2015 10:05 am | by Harvard University | Comments

A team of researchers has identified more than 40 new “imprinted” genes, in which either the maternal or paternal copy of a gene is expressed while the other is silenced. The findings, described in a recent paper in eLife, reveal how genomic imprinting can dramatically expand biological diversity, and could have important implications for understanding the brain.
