Lion Cub / Zoo Antwerp

Patience has paid off for fans at Zoo Antwerp. The lion cub born there on 29 August made its public debut this week. The cub spent the first month of its life indoors with its mother, Maouli, but is now enjoying time in an outdoor pen where it can be seen by visitors — via ZooBorns

White Rhino / Burgers Zoo

Keepers at The Netherlands’ Burgers Zoo were surprised by the early birth of a baby White Rhino. 12-year-old female, Kwanzaa, and her new calf Vince are stable and healthy, according to zoo officials. Of the five rhino species in existence, White Rhinoceros are the most social. They are listed as Near Threatened on the IUCN Red List — via ZooBorns

Fish skin points to better LEDs

A trick of the light evolved by silvery fish to avoid predators could help improve optical devices like LEDs, according to a study in Nature Photonics.

While polarisation has many applications in photonics, non-polarising devices are also important. The research – abstract here — took a look at how fish such as sardines and herring reflect light without polarising it.

PhD student Tom Jordan from the Bristol Centre for Complexity Sciences, and his supervisors Professor Julian Partridge and Dr Nicholas Roberts in Bristol’s School of Biological Sciences, found that these fish avoid reflecting polarised light by having two types of reflective crystals in their skins.

The crystals are guanine, which as Discovery points out is also a component of guano. A single guanine crystal layer in the scales would polarise the light reflected, which would also dim the reflected light — via redwolf.newsvine.com

Baby Brazilian Tapir / Zoo Tel Aviv

Only 15 months ago, Zoo Tel Aviv‘s 7-year-old Tapir mother gave birth to her first calf. Now the zoo is celebrating the arrival of its first male ever male calf. The spotted bundle of joy weighs only 11 pounds and has already begun to explore his exhibit. Now experienced mother Passiflora has demonstrated outstanding mothering skills, but to ensure that her baby gets enough milk, keepers coax her to lie on her side with belly rubs. Father Tapiro is spending these first days separated from mum and her calf to allow them a stress free bonding period — via ZooBorns

Spider Silk Makes Great Microchips That Dissolve in the Human Body

Spider silk is pretty amazing stuff. Pound for pound, it’s as strong as steel and more durable than Kevlar. It can be stretched to incredible lengths, but it’s no more cumbersome than cotton or nylon. Because it’s so awesome, scientists have long been searching for good ways to synthesize the stuff (it’s not exactly easy to milk spiders in any meaningful quantity), and they’ve made some good progress. Thanks to the latest work from biomedical engineer Fiorenzo Omenetto of Tufts University in Boston and Nolwenn Huby from the CNRS Institut de Physiques de Rennes in France, they’ll have a little extra motivation to get it done soon.

Omenetto and Huby are both presenting their work on Monday at a conference in Rochester, New York. It’s hard to tell who’s more impressive. Omenetto’s team is developing silk-based materials that look and act like plastic, but because of their unique chemical makeup, are completely and safely biodegradable. That means they could build special microchips that could be implanted inside of the body to serve a particular purpose and simply dissolve when the job’s done. A broken bone, for instance. Doctors might not be completely sure when the bone will be healed could theoretically implant one of their spider silk microchips onto the bone to monitor the progress, and it would simply disappear when everything is back to normal — via redwolf.newsvine.com

Berani the Malayan Tiger / Point Defiance Zoo & Aquarium

Dumai, Point Defiance Zoo & Aquarium‘s Sumatran Tiger cub, is getting a new buddy. Meet Berani, a 5-week-old Malayan male cub scheduled to arrive at Point Defiance this week from Tulsa Zoo and Living Museum. Each was the only cub in a litter and pulled from mum within days of birth because the tiny Tigers were not thriving. Once Berani arrives and is checked out, you will be able to see him in the cub den playing and pouncing with Dumai — via ZooBorns

Red Pandas / Whipsnade Zoo

The Zoological Society of London’s Whipsnade Zoo is getting a glimpse of their Red Panda twins for the first time since they were born in June. The girls, named Yin and Yang, have stayed close to first-time mum, Tashi, for the last few months, and are only now beginning to take tentative steps to explore their surroundings — via ZooBorns

Cephalopod Studs / UntamedMenagerie

Rusty-Spotted Cats / Berlin Zoo

The Berlin Zoo is celebrating the first birth of Rusty-Spotted Cats in its 168-year history. Rusty-Spotted Cats are the world’s smallest wild cats, weighing only 0.9 to 1.6kg as adults.

The two kittens were born on 5 August and have only recently begun to leave their den to explore their exhibit. Playful, clumsy, and a little awkward, the two female youngsters are a delight to zoo guests. At birth, kittens typically weigh just 60-77g.

Oriental Small-clawed Otters / Edinburgh Zoo

Edinburgh Zoo‘s Oriental Small-clawed Otters welcomed five newborns to the raft in July this year — and now the 10 week old pups have started venturing out and about in their enclosure. The quintuplets were born to mum Elena and dad Ray — their third litter since arriving at the Zoo, making them experts when it comes to rearing pups. The youngsters have only recently started to explore their new surroundings under the watchful eyes of their older sisters, Eliza and Aisha, and of course their protective parents. Keepers have sexed the 10 week olds as three females and two males, who have yet to be named — via ZooBorns
