Turtles May Hold the Key to Protecting Human Hearts after Heart Attack

In humans, going just minutes without oxygen—such as during a heart attack or stroke—can cause devastating damage to the heart. Researchers looking to freshwater turtles to understand the mechanisms that protect them from heart damage after long hibernation periods will present their findings at the Physiological Bioenergetics: Mitochondria from Bench to Bedside conference in San Diego.

Chemists Get Step Closer to Replicating Nature with Assembly of New 3D Structures

A team of chemists has created a series of three-dimensional structures that take a step closer to resembling those found in nature. The work offers insights into how enzymes are properly assembled, or folded, which could enhance our understanding of a range of diseases that result from these misfolded proteins.

You and Some 'Cavemen' Get a Genetic Checkup

Evolution has weeded out genetic variants associated with diseases for millennia and propagated genetic variants that protect against ailments, a comparative genetics study shows. But that good trend may have recently gone in reverse.

Treating Arthritis with Algae

Researchers at ETH Zurich, Empa and the Norwegian research institute SINTEF are pursuing a new approach to treating arthritis. This is based on a polysaccharide, a long-chain sugar molecule, originating from brown algae. When chemically modified, this "alginate" reduces oxidative stress, has an anti-inflammatory effect in cell culture tests and suppresses the immune reaction against cartilage cells, thereby combating the causes of arthritis. The research is, however, still in its infancy.

Stretchable Biofuel Cells Extract Energy From Sweat to Power Wearable Devices

A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. The biofuel cells generate 10 times more power per surface area than any existing wearable biofuel cells. The devices could be used to power a range of wearable devices.

Can a group of three single-celled, algae-like organisms produce high quantities of sugar just right for making biofuels? Laboratory results indicate that they can. Sandia National Laboratories is helping Bay Area-based HelioBioSys understand whether these cyanobacteria can be grown large scale.
