HIV antibodies neutralize 88% of worldwide HIV types & 2/3 of subtype C

A unique change in the outer covering of the virus allowed for antibodies to attach and neutralize 88% if HIV types around the world. This is known as a broadly neutralizing antibody response and was due to the body pressuring the virus to change its surface coating to have a sugar (glycan) ‘tag’ in the 332 position which then allowed the immune systems antibodies to attack it.

According to Professor Salim Abdool Karim, president of the Medical Research Council, “Broadly neutralizing antibodies are considered to be the key to making an AIDS vaccine. This discovery provides new clues on how vaccines could be designed to elicit broadly neutralizing antibodies.”

Though, because the weak point at position 332 is only in ~70% of the subtype C viruses (the subtype most common in Africa), antibodies will need to be developed that can target more glycans on the virus.

Nanofilm Prevents Premature Implant Failures

Every year, more than a million Americans receive an artificial hip or knee prosthesis. Such implants are designed to last many years, but in about 17 percent of patients who receive a total joint replacement, the implant eventually loosens and has to be replaced early, which can cause dangerous complications for elderly patients.

To help minimize these burdensome operations, a team of MIT chemical engineers has developed a new coating for implants that could help them better adhere to the patient’s bone, preventing premature failure.

freshphotons:

“The image is the result of fiber tractography from diffusion-weighted magnetic resonance imaging. It illustrates the white matter of the brain, or in other words, its structural connections. The red smooth surface represents a glioblastoma tumor. We can see the effect of repulsion and infiltration of this mass on the white matter fiber pathways. A distance colormap is used for interpretation. Blue fibers mean that they are located within a safe distance of the tumor whereas red fibers are in a close perimeter to the tumor, and can cause severe post-operation deficits, if resected.” -Cerebral Infiltration, Maxime Chamberland, David Fortin, Maxime Descoteaux, Sherbrooke Connectivity Imaging Lab.

wildcat2030:

Engineers and designers are giving commercial aircraft a makeover, in a bid to make them faster, greener and more efficient. Look up into the skies today at a passing aeroplane and the view is not that much different to the one you would have seen 60 years ago. Then and now, most airliners have two wings, a cigar-shaped fuselage and a trio of vertical and horizontal stabilizers at the tail. If it isn’t broke, the mantra has been, why fix it, particularly when your design needs to travel through the air at several hundred miles an hour packed with people. But that conservative view could soon change. Rising fuel prices, increasingly stringent pollution limits, as well as a surge in demand for air travel, mean plane designers are going back to their drawing boards. And, now, radical new shapes and engine technologies are beginning to emerge, promising the biggest shake-up in air travel since de Haviland introduced the first commercial jet airliner in 1952. Of course, it would be wrong to say nothing has changed in the last few decades, says Rich Wahls, an aerodynamicist at Nasa’s Langley Research Center in Hampton, Virginia. “New model airliners don’t come out every year like cars, but it’s not as if they haven’t been evolving under the skin the whole time. There’s so much more technology in there nowadays.” (via BBC - Future - Technology - Radical planes take shape)

Spider and moulted exoskeletons. Coloured environmental scanning electron micrograph (ESEM) of a Theridion spider (upper left) and several moulted exoskeletons (right). The spider’s eyes, legs and mouthparts are also seen. Moulting takes place several times during a spider’s lifetime, but most often when it is young and growing. To shed the old exoskeleton, the spider swells and flexes its muscles to split it, and then crawls forward and pulls its legs out of the old exoskeleton.
