Do Wolves Kill for Sport?

A gray wolf

From Slate:

No, but sometimes they hunt down more than they can eat.

During this fall's inaugural wolf-hunting season in Montana, hunters killed the matriarch of a Yellowstone wolf pack that researchers had been studying for more than a decade. Park officials suspect that her mate and three other pack members were also killed. A Los Angeles Times story about the hunt claims that wolves are known to kill for "pure pleasure." Do wolves really attack their prey just for the fun of it?

Scientists Develop Apple That Won't Rot

The RS103-130, which is a deep red in colour, stays "crispy" for up to 14 days if kept in a fruit bowl - unlike most apples. Alamy

From The Independent:

Ever since somebody suggested that eating one a day kept the doctor away, the health benefits of the apple have been trumpeted by grandmothers and government ministers alike. The fruit's only drawback is its tendency to lose its glossy sheen and crunchy texture within a few days – a problem that a team of scientists in Australia now claims to have solved.

For the past 20 years, researchers at Queensland Primary Industries and Fisheries (QPIF), a department of the Queensland government, have been developing a new variety of apple which they claim can stay fresh for months.

The Sea Change That's Challenging Biology's Central Dogma

Image: National Institute of General Medical Sciences

From Discover Magazine:

For decades, RNA was seen as a simple slave to DNA. Newer research shows it has an active and critical role in every disease from Alzheimer's to cancer.

One of the great revolutions in modern science rests on the elongated backside of a grotesque, mutant worm. Inexpensive and easy to manipulate in the lab, Caenorhabditis elegans develops from egg to adult in three days and produces a few hundred offspring three days after that. Virtually all of the worms are hermaphrodites, containing both male and female sex organs and capable of making sperm and eggs, so each creature can fertilize itself. And because the worm is transparent and the adult has only 959 cells, development of every stage from egg to adult can be observed under the microscope and documented with near perfect detail while the worm is alive, an achievement accomplished in the 1970s by Sidney Brenner, a University of Cambridge researcher and legend in the field.

Genes Show When A Woman's Biological Clock Will Stop

Is time running out? (Image: Altrendo Images/Stockbyte/Getty)

From New Scientist:

IT IS a dilemma facing a growing number of young women: can I delay having a baby until my career is more established? A genetic test that could make this decision less of a gamble might be on offer by next year, thanks to the discovery of a gene that seems to predict the rate at which a woman's egg supply diminishes.

No one is yet sure how useful the test will be. But the aim is to tell a woman in her early 20s whether she is at high risk of early menopause. If she is, monitoring her egg supply will confirm whether her fertility is in early decline. Armed with this information she could then decide whether to start a family sooner or later, or freeze some eggs to increase her chances of conceiving later on.
