After a heart attack occurs, non-beating scar tissue forms on the part of the organ that was affected – and this can lead to heart failure. There could be new hope, however, in the form of an implanted device that delivers medication directly to that tissue.

Direct air capture (DAC) systems have been discussed as a possibility for removing CO2 from the air, but until recently seemed too expensive. After running a pilot plant for three years, Carbon Engineering (CE) has broken down the costs of a DAC system and found how it can work.

In response to exercise, scientists have now observed a big spike in levels of a fat hormone previously thought to be unrelated to physical exertion. The discovery sheds new light on the metabolic process and raises new targets for tackling weight loss.

There may be new hope for people who are losing their hearing, thanks to research being conducted by scientists from the University of Southern California and Harvard University. They've developed a solution intended to stay put in the inner ear, where it will help repair cells.

Bacteria can be hardy little creatures, thanks mostly to their strong cell walls. Now researchers at Harvard have identified a structural weakness that seems to be built into a range of bacterial species, potentially paving the way for a new class of widely-effective antibacterial drugs.

Harvard has reported a breakthrough artificial eye just 30 microns in depth which can exceed the capabilities of the human eye. The technology could make a real impact in all manner of optical fields, including those in cameras, telescopes, microscopes, glasses and even virtual reality.

As tiny as they are, there's a relatively large amount of empty space inside an atom. Now, scientists from Austria and the US have filled in some of those gaps, creating a new state of matter in the form of "giant atoms" filled with other atoms.

Though inspired by the snake, a new soft robot out of Harvard takes cues from another source: the Japanese paper craft kirigami. Unlike origami, kirigami uses cuts rather than folds. Here, the Harvard team have applied the artform to create a soft robot that grips the ground much like a snake.

Photons, the elementary particles that make up light, are fast, weightless and don't interact with each other. But in new experiments, physicists have now created a new form of light, demonstrating that groups of photons can be made to interact with each other, slow down and gain mass.

A team of biologists and engineers from Harvard University and the University of South Carolina have taken a fresh look at shark scales in the hopes of making drones, planes and wind turbines more efficient.
