Rare chickens brought back from the brink of extinction by Edinburgh University

R

are chickens such as the ‘Scots Dumpy’ which was used by the Picts to warn of the approach of the Roman Army, could be brought back from the brink of extinction by Edinburgh University.

Scientists have genetically engineered chickens which can act as surrogates and lay the eggs of other rare breeds.

The surrogates themselves are sterile and so cannot produce their own offspring. But when the stem cells from rare chicken breeds are implanted into their reproductive tissue, they go on to produce eggs and ultimately chicks from the threatened species.-read more

Woolly Mammoths could be 'de-extinct' in 2 years

This whole nostalgia thing is getting out of control because scientists are about to bring back the woolly mammoth, the Guardian reports.

Harvard professor George Church—who New Scientist calls a "maverick geneticist"—is leading a "de-extinction" team that says it's about two years away from creating a hybrid embryo combining mammoth traits with Asian elephant DNA.

Woolly mammoths went extinct about 4,000 years ago due to human hunting and warming temperatures. But in the past few years, Church and his team have managed to splice 45 mammoth edits into Asian elephant DNA, including ones that control for a mammoth's shaggy hair, small ears, fat layers, and more.

While Church and his team believe they can have a "mammophant" embryo in two years, it will be much longer before anyone sees one in the wild. The team wants to grow mammophants completely in a lab in order to not mess with the reproduction of endangered Asian elephants, and that technology doesn't exist -read more

Backyard Worlds: Join Search for Planet Nine, Nearby Brown Dwarfs

A NASA-funded website called Backyard Worlds: Planet 9 lets everyone participate in the search for the hypothetical Planet Nine and ‘failed’ stars in the solar neighborhood by viewing brief movies made from images captured by NASA’s Wide-field Infrared Survey Explorer (WISE).“Backyard Worlds: Planet 9 has the potential to unlock once-in-a-century discoveries, and it’s exciting to think they could be spotted first by a citizen scientist,” said Dr. Aaron Meisner, a researcher at the University of California, Berkeley, who specializes in analyzing WISE images.

The new website relies on human eyes because we easily recognize the important moving objects while ignoring the artifacts. It’s a modern version of the technique astronomer Clyde Tombaugh used to find Pluto in 1930.

On the website, people around the world can work their way through millions of ‘flipbooks,’ which are brief animations showing how small patches of the sky changed over several years.

Moving objects flagged by participants will be prioritized by the science team for follow-up observations by professional astronomers.

Participants will share credit for their discoveries in any scientific publications that result from the project.

“There are just over 4 light-years between Neptune and Proxima Centauri, the nearest star, and much of this vast territory is unexplored,” said Dr. Marc Kuchner, an astrophysicist at NASA’s Goddard Space Flight Center.”-read more

Nelson's captured French Tricolour flag displayed again

A French flag presented to Norwich by Admiral Lord Nelson after it was captured in battle is to go on display for the first time in 100 years.

The ensign of Le Genereux, believed to be one of the earliest Tricolours in existence, was captured in 1800.

Conservation work on the 16m by 8.3m (52ft by 27ft) flag, which still contains splinters of wood and traces of gunpowder, will cost about £40,000.

Norwich Castle said it is "a remarkable survivor" of sailing ship battles.-read more

melanoma-warning-signs-and-images

Even if you have carefully practiced sun safety all summer, it's important to continue being vigilant about your skin in fall, winter, and beyond. Throughout the year, you should examine your skin head to toe once a month, looking for any suspicious lesions. Self-exams can help you identify potential skin cancers early, when they can almost always be completely cured.

First, for a successful self-exam, you obviously need to know what you're looking for.  As a general rule, to spot either melanomas or non-melanoma skin cancers (such as basal cell carcinoma and squamous cell carcinoma), take note of any new moles or growths, and any existing growths that begin to grow or change significantly in any other way.  Lesions that change, itch, bleed, or don't heal are also alarm signals.

It is so vital to catch melanoma, the deadliest form of skin cancer, early that physicians have developed two specific strategies for early recognition of the disease: the ABCDEs and the Ugly Duckling sign.read more

Elton the tiger gets a visit from the dentist

A dentist who has expertise in treating nature’s giants was called upon to treat Elton the tiger this week. Woburn Safari Park’s Amur tiger needed urgent treatment after breaking one of his canine teeth.

Dr Peter Kertesz, one of the world’s leading zoological dentists, was asked to visit Elton and perform dental surgery to repair the damaged tooth. In the wild, a dental infection could result in severe complications, and even death. Fortunately, the eagle-eyed keepers at the park spotted that something was wrong, and Elton s not recovering after undergoing surgery.

Dr Kertesz was assisted by a team during the procedure, which began once the Amur tiger had been sedated. The procedure, which was captured on film, involved cleaning the tooth, filling the holes in the canine tooth to prevent further infection, and fitting a moulded filling to strengthen the tooth.

Once Dr Kertesz had finished operating on Elton, he was encouraged to come around slowly, and he spent 24 hours in recovery sleeping off the effects of anaesthetic.

After his dental dramas, Elton has now made a full recovery. Dental infections can be incredibly dangerous for tigers, especially in the wild when they rely on hunting to catch and kill their prey. The team is trained to spot even the most minor injuries and swift action helped to save Elton’s troublesome tooth and prevent him from suffering pain and any long-term damage.
