Do birds go through menopause? A 60-year-old Laysan albatross, the oldest known wild bird in the United States, hatched a chick a few weeks ago in the Midway Atoll (a U.S. territory), despite the fact that most members of her species live only to 30.

Do birds go through menopause?

The geriatric bird, known to wildlife researchers as Wisdom, has probably raised three dozen offspring in her lifetime. Here’s Every Single Animal That Became Extinct In The Last 100 Years (PHOTOS) The number of extinct animals is difficult to calculate and always higher than the estimate.

Here’s Every Single Animal That Became Extinct In The Last 100 Years (PHOTOS)

In some cases, a species is presumed extinct — none have been seen in years — but it’s yet to receive official extinction status by the IUCN. But the important thing to remember is that extinction is not a historical problem — it’s a contemporary issue. Below, take a look at every animal (except insects, which are extremely difficult to catalogue but which you can find here) that went extinct in just the last 100 years. The list is based on research provided by the Sixth Extinction, a website created to “enhance free public access to information about recently extinct species,” and in order of their approximate date of extinction. We’ve included all the animals confirmed extinct by the IUCN, and added a few more declared extinct by other credible individuals and organizations.

Companion Animal Psychology: Are young children more interested in animals than toys? At what age do children develop a fascination with animals?

Companion Animal Psychology: Are young children more interested in animals than toys?

A brand new paper by Vanessa LoBue et al investigates young children’s interest in live animals. A set of three studies looked at young children in a naturalistic play environment in which they could choose to interact with animals or toys. The animals were always in an enclosure, so the children could only look at them and not physically touch them. One obvious difference between animals and toys is that the animals move. Sifaka. Sifakas (singular "sifaka"; i/ʃɪˈfɑːk/; Malagasy pronunciation: [ˈsifakə̥] ( Sifakas are medium sized indrids with a head and body length of 40 to 55 centimetres (16 to 22 in) and a weight of 3 to 6 kilograms (6.6 to 13.2 lb).

Sifaka

Their tail is just as long as their body, which differentiates them from the Indri. Their fur is long and silky, with coloration varying by species from yellowish-white to black brown. The round, hairless face is always black. Sifakas move by vertical clinging and leaping, meaning they maintain an upright position leaping from tree trunk to tree trunk and moving along branches. Sifakas are herbivores, eating leaves, flowers and fruits. A four to five month gestation period ends with the birth of a single offspring in July. Sifakas hop side-to-side when moving on the ground.

'Quadruple helix' DNA discovered in human cells

Now, in the year of that scientific landmark's 60th Anniversary, Cambridge researchers have published a paper proving that four-stranded 'quadruple helix' DNA structures - known as G-quadruplexes - also exist within the human genome. They form in regions of DNA that are rich in the building block guanine, usually abbreviated to 'G'. The findings mark the culmination of over 10 years investigation by scientists to show these complex structures in vivo - in living human cells - working from the hypothetical, through computational modelling to synthetic lab experiments and finally the identification in human cancer cells using fluorescent biomarkers.

"The research indicates that quadruplexes are more likely to occur in genes of cells that are rapidly dividing, such as cancer cells.

After sex without reproduction, reproduction without sex. The Psychology of Human Sexuality - Oddities In The History Of Sex Research: Homosexual Necrophilia In The Mallard Duck. As I have discussed in previous blog posts, a number of unusual sexual behaviors have been documented in human beings, from cutting a hole in one’s pants in order to masturbate easily in public to letting insects bite one’s genitals during sexual activity. However, humans aren’t the only ones with curious sexual proclivities—unusual behaviors also occur in the animal kingdom with some frequency. In this post, I’d like to share what is perhaps the most interesting scientific study of animal sexuality I have ever come across [1]. Archives of Toxicology, Volume 85, Number 5. The 7th amendment to the EU Cosmetics Directive prohibits to put animal-tested cosmetics on the market in Europe after 2013.

In that context, the European Commission invited stakeholder bodies (industry, non-governmental organisations, EU Member States, and the Commission’s Scientific Committee on Consumer Safety) to identify scientific experts in five toxicological areas, i.e. toxicokinetics, repeated dose toxicity, carcinogenicity, skin sensitisation, and reproductive toxicity for which the Directive foresees that the 2013 deadline could be further extended in case alternative and validated methods would not be available in time. The selected experts were asked to analyse the status and prospects of alternative methods and to provide a scientifically sound estimate of the time necessary to achieve full replacement of animal testing. Botany of Desire (2009) - full. What Animals Can Change Their Sex?

Many creatures in the sea have evolved to become asexual or hermaphroditic to increase their chances at continuing their species. A type of sea snail known as a sea hare, for example, is shell-less with male genitalia in their fronts and female genitalia behind them. Another ocean dweller is the slipper limpet, which is male while swimming around freely, but changes to female when on rocks. The reason for this change is that the male swimming by a female on a rock is readily able to mate. That same male, however, could turn female if another limpet lands on top of him while he mates with the female. Then there are the hamlets, small fish of the tropics that simultaneously take on both the male and female roles when mating, shifting from one sex to the other in under 30 seconds.

A research team involving Yale University and the University of Colorado Boulder has developed a first public demonstration version of its "Map of Life," an ambitious Web-based endeavor designed to show the distribution of all living plants and animals on the planet. The demonstration version allows anyone with an Internet connection to map the known global distribution of almost 25,000 species of terrestrial vertebrate animals, including mammals, birds, amphibians, reptiles and North American freshwater fish.

The database, which continues to expand, already contains hundreds of millions of records on the abundance and distribution of the planet's diverse flora and fauna. Map of Life.
