Proven: Gorillas have human emotions

Gorilla grieves over death of her baby

A female gorilla has been photographed grieving over the loss of her baby, showing a strength of emotion rarely witnessed in the animal world.

Gorilla Gana, 11, was left shattered in her compound at the zoo in Muenster in northern Germany at the weekend when her three-month-old baby Claudio suddenly died.

Visitors wept as Gana held her lifeless child up in the air, vainly seeking to restore movement to his lolling head, his limp arms.

She put the baby on her back and walked around, stopping to look at him after a few paces to see if he had recovered.

"On Wednesday he gave the impression to keepers that he wasn't feeling too well.

"On Friday he wasn't eating or drinking properly and seemed to be growing weaker.

"We were keeping a close eye on him but suddenly, on Saturday morning, he died."

By Monday morning the zoo keepers were still unable to get to the body of Claudio, so fiercely is Gana guarding him.

Polygamy is the key to a long life

clipper's remarks: Men, by contrast, can reproduce well into their 60s and even 70s and 80s, and most researchers assumed this explained their longevity. But Lummaa and colleague Andy Russell wondered whether other factors explained the long lifespan of men, such as a grandfather effect.
If female survival is the main explanation for male longevity, then monogamous and polygamous men would live for about the same length of time. Instead, it seems that fathering more kids with more wives leads to increased male longevity. Men, then, live long because they're fertile well into their grey years.

The explanation could be both social and genetic. Men who continue fathering kids into their 60s and 70s could take better care for their bodies because they have mouths to feed. But evolutionary forces acting over thousands of years could also select for longer-lived men in polygamous cultures.

Want to live a little longer? Get a second wife. New research suggests that men from polygamous cultures outlive those from monogamous ones.

After accounting for socioeconomic differences, men aged over 60 from 140 countries that practice polygamy to varying degrees lived on average 12% longer than men from 49 mostly monogamous nations, says Virpi Lummaa, an ecologist at the University of Sheffield, UK.

Rather than a call to polygamy, the research might solve a long-standing puzzle in human biology: Why do men live so long?

This question only makes sense after asking the same for women, who - unlike nearly all other animals - live long past the menopause.

One answer seems to be a phenomenon called the grandmother effect. For every 10 years a woman survives past the menopause, she gains two additional grandchildren, Lummaa says. It seems that doting on and spoiling grandchildren aids their survival, as well as furthering some of their grandmother’s genes.

Potential Alzheimer's, Parkinson's Cure Found In Century-old Drug

clipper's remarks: Also impressed is one of Dr. Atamna's co-authors, Bruce Ames, PhD, a senior scientist at Children's and world-renowned expert in nutrition and aging. "What we potentially have is a wonder drug." said Dr. Ames. "To find that such a common and inexpensive drug can be used to increase and prolong the quality of life by treating such serious diseases is truly exciting."

Dr. Atamna's research is the first to show that low concentrations of the drug have the ability to slow cellular aging in cultured cells in the laboratory and in live mice. He believes methylene blue has the potential to become another commonplace low-cost treatment like aspirin, prescribed as a blood thinner for people with heart disorders.

A new study conducted by researchers at Children's Hospital & Research Center Oakland shows that a century-old drug, methylene blue, may be able to slow or even cure Alzheimer's and Parkinson's disease.

Used at a very low concentration – about the equivalent of a few raindrops in four Olympic-sized swimming pools of water – the drug slows cellular aging and enhances mitochondrial function, potentially allowing those with the diseases to live longer, healthier lives.

Dr. Atamna's research found that methylene blue can prevent or slow the decline of mitochondrial function, specifically an important enzyme called complex IV. Because mitochondria are the principal suppliers of energy to all animal and human cells, their healthy function is critical.

"The results are very encouraging," said Dr. Atamna. "We'd eventually like to try to prevent the physical and cognitive decline associated with aging, with a focus on people with Alzheimer's disease.

The Witch's Broom Nebula

Explanation: Ten thousand years ago, before the dawn of recorded human history, a new light must suddenly have appeared in the night sky and faded after a few weeks. Today we know this light was an exploding star and record the colorful expanding cloud as the Veil Nebula. Pictured above is the west end of the Veil Nebula known technically as NGC 6960 but less formally as the Witch's Broom Nebula. The expanding debris cloud gains its colors by sweeping up and exciting existing nearby gas. The supernova remnant lies about 1400 light-years away towards the constellation of Cygnus. This Witch's Broom actually spans over three times the angular size of the full Moon. The bright star 52 Cygnus is visible with the unaided eye from a dark location but unrelated to the ancient supernova.
