The Age Of Enhancement

From Prospect:

A cornucopia of drugs will soon be on sale to improve everything from our memories to our trust in others.

On 6th December 2004 a baby girl named Yan was born. Her father, an internet entrepreneur, is called Shen Tong. Yan was Shen’s first child, and you might have expected him to have an excitable, sleepless night. But oddly the opposite occurred. He slept better than he had done for 15 years, six months and two days. It’s possible to be exact about the timing because 15 years, six months and two days earlier was 4th June 1989 and on that day Shen had been on a boulevard just off Tiananmen Square in Beijing. He was a 20-year-old student, and like thousands of others he was demonstrating in favour of political reform.

Memory Scientists Say: All Is Not Forgotten

fMRI Brain Activity Jan Hardenbergh

From Popular Science:

Unless you are this woman, you probably have a long mental list of moments and facts you wish you could remember -- but for the life of you, you can't. To use a personal example, I periodically Google the words "yellow house Berlin," hoping to produce the name of that one hostel I lived in for a summer in college; alas, no success yet. The good news, though, is that while such memories may be currently inaccessible, they're not entirely gone, and could theoretically be retrieved, according to new brain imaging research from the University of California, Irvine.

High cholesterol levels could prevent women from becoming sexually aroused
(Image: F1 Online / Rex Features)

From New Scientist:

High cholesterol isn't just bad for the heart – it could also make it harder for women to become sexually aroused. That might mean that cholesterol-lowering drugs like statins would help to treat so-called female sexual dysfunction (FSD).

Hyperlipidemia, or raised levels of cholesterol and other fats in the blood, is associated with erectile dysfunction in men, because the build-up of fats in blood vessel walls can reduce blood flow to erectile tissue. Since some aspects of female sexual arousal also rely on increased blood flow to the genitals, Katherine Esposito and her colleagues at the Second University of Naples in Italy compared sexual function in premenopausal women with and without hyperlipidemia.

When two husbands are better than one

Women laborers work in an onion field at Rambha village of Karnal district in the northern Indian state of Haryana on April 30, 2009. A shortage of females in this area has led to more people participating in polyandry, or the phenomenon of a woman taking more than one husband. (Vijay Mathur/Reuters)

From Global Post:

Polyandry in the Himalayas is a complex affair. Not surprisingly.

SPITI VALLEY, HIMACHAL PRADESH, India — An array of stars twinkled over Himalayan peaks towering nearly three miles high, while below in the chilly darkness a husband and wife relaxed after their 120-mile pilgrimage. Leaning back in chairs in front of a guest house, warm in their woolen clothing, they appeared indistinguishable from the hundreds of others who had come to hear the teachings of a Buddhist leader.

What set them apart was the person they had left behind: the woman's other husband.

From Discover Magazine:

Neuroscientists explore the mind's sexual side and discover that desire is not quite what we thought it was.

On April 11, 1944, a doctor named T. C. Erickson addressed the Chicago Neurological Society about a patient he called Mrs. C. W. At age 43 she had started to wake up many nights feeling as if she were having sex—or as she put it to Erickson, feeling “hot all over.” As the years passed her hot spells struck more often, even in the daytime, and began to be followed by seizures that left her unable to speak. Erickson examined Mrs. C. W. when she was 54 and diagnosed her with nymphomania. He prescribed a treatment that was shockingly common at the time: He blasted her ovaries with X-rays.

Ancient 'Smell Of Death' Revealed

Dying stinks, even for woodlice

From The BBC:

When animals die, their corpses exude a particular "stench of death" which repels their living relatives, scientists have discovered.

Corpses of animals as distantly related as insects and crustaceans all produce the same stench, caused by a blend of simple fatty acids.

The smell helps living animals avoid others that have succumbed to disease or places where predators lurk.

This 'death recognition system' likely evolved over 400 million years ago.

The discovery was made by a team of researchers based at McMaster University, near Hamilton, Ontario, Canada, and is published in the journal Evolutionary Biology.

From Technology Review:

New research shows that explosions trigger unique damage to brain tissue.

The blasts caused by improvised explosive devices in Iraq and Afghanistan appear to inflict a fundamentally different type of brain damage than do more traditional sources of concussions, such as blunt trauma. The findings point toward new approaches to diagnosing and monitoring these injuries, which have been a huge concern to the military in recent years. The research also begins to resolve a controversy in brain-injury research--whether soldiers who are near an explosion but don't get hit in the head can still suffer a unique type of brain damage.
