The shape of a centuries-old Buddhist singing bowl has inspired a Canberra scientist to re-think the way that solar cells are designed to maximize their efficiency.

Dr Niraj Lal, of the Australian National University,  found during his PhD at the University of Cambridge, that small nano-sized versions of Buddhist singing bowls resonate with light in the same way as they do with sound, and he’s applied this shape to solar cells to increase their ability to capture more light and convert it into electricity.

“Current standard solar panels lose a large amount of light-energy as it hits the surface, making the panels’ generation of electricity inefficient,” says Niraj. “But if the cells are singing bowl-shaped, then the light bounces around inside the cell for longer”.

Pet abuse and domestic violence are closely linked. Animals can’t talk but University of Sydney vet Dr Lydia Tong has shown vets how to tell the difference between bone fractures caused by accidents and those caused by abuse. Her fracture identification methods are giving vets the added confidence to identify cases of violence against pets and could serve as a warning of domestic violence.

Now, in a new study with Domestic Violence NSW, Lydia is looking deeper into the connections between animal abuse and domestic violence to assess the need for better services to protect both human and animal victims.

“Around 70% of women escaping violent homes also report pet abuse,” says Lydia. “So vets are often the first to see evidence of abuse in a family, when they treat injured pets.”

“Different forces on bones can tell a story—the skeleton of an animal keeps a distinct record that indicates the force applied to bones from past injuries, breaks or fractures. But it can often be difficult for vets to say with confidence whether a fracture has resulted from abuse or accident.”

To give vets this confidence, in a 2014 study, Lydia collected cases of abused dogs who were punched, hit with a blunt weapon or kicked, and examined the fractures from these injuries. She then compared these fractures to those caused by genuine accidents. Her results, published in The Veterinary Journal, identified five key features of fractures that vets could look for to distinguish accidents from abuse.

Now, having given vets this reference to diagnose abuse, Lydia and her colleagues at The University of Sydney are gathering more information on the connections between domestic violence and animal abuse. [Read more…] about Can vets help fight domestic violence by identifying pet abuse?
