Body size and shape are significant factors in how efficiently an individual responds physiologically to cold and hot climates. When the environment is very cold, life can depend on the ability of our bodies to reduce heat loss and to increase internal heat production. As Bergmann and Allen observed, the human physiological response to cold […]

Certain features of the face are built by testosterone,” said Helen Fisher. Those stereo-typically masculine features include a strong, square jaw, prominent brow ridges, high cheekbones, thin lips and a high forehead. What is a bit spooky is that upper body strength can even be read on a person’s face. What it is in the […]

A Canadian study indicates that the female sex hormone oestrogen gives women’s immune systems added bite at fighting off infection. The researchers believe women may have evolved a more robust immune system because of their key role in producing and nurturing young. Oestrogen seems to counter an enzyme which blocks the inflammatory process. The researchers […]

Research published by the Royal Society indicates that a woman can accurately establish a man’s masculinity and his affinity for children simply by looking at a picture of his face. Women also made judgments about long-term and short-term relationships by looking at a man’s face. –Brazilian Model Larissa Diniz, UK Photographer Michael Sheller Women and men […]

Professor Tantam thinks the center for this brain wi-fi is in the prefrontal cortex, where the neuron activity associated with the senses of smell and sight are located. That activity may activate the sense of sight to make eye contact or pick up minute visual clues to what the other person might be thinking. This […]

At a certain time of the month, men can smell that women are more attractive. So it’s the time when women are most fertile, and men seem to be biologically programmed to pick up on that. Scientists have had men smell women’s T-shirts and underarm patches, and men consistently rate the women who are ovulating […]

Psychologists at the University of Texas have discovered that women look and feel more attractive when they are at their most fertile. The women also changed physically. Their waists shrank by about half an inch, giving them a more curvaceous and shapely silhouette, and their breasts were likely to be more symmetrical. We learned beyond a […]

Research shows that physical affection has measurable health benefits. “Stimulating touch receptors under the skin can lower blood pressure and cortisol levels, effectively reducing stress,” Hertenstein says. One study from the University of North Carolina found that women who hugged their spouse or partner frequently (even for just 20 seconds) had lower blood pressure, possibly […]

IRCCS San Camillo Hospital Foundation in Venice, shows that people with an ‘O’ blood type have more grey matter in their brain, which helps to protect against diseases such as Alzheimer’s, than those with ‘A’, ‘B’ or ‘AB’ blood types. The researchers calculated the volumes of grey matter within the brain and explored the differences […]

New research reveals that women are prone to be kinder and more generous than men. When a woman exhibits some form of kindness, it triggers a greater reward signal than it does in men. Women may at times have higher levels of “oxytocin” – sometimes called the “cuddle hormone” or “love hormone” because it is linked […]

Research has shown, for example, that women retain more strength in their legs after running a marathon or cycling for a long period of time. Ladies, you now have some science-backed bragging rights: Women can exercise for longer than men before getting tired, according to a new scientific review. If men and women fatigue differently, they […]

People can recognize the smell of their close family members – but surprisingly, they do not like it. When asked which smells they liked, the answers were even more intriguing. The volunteers far preferred the smells of other people to those of their own family members. Czilli then asked everyone to sniff two T-shirts, one […]

A common aim is to identify specific features that possibly evolved as signals indicating mate breeding potential. Several cross-cultural studies have already determined that men from all countries and from all races tend to find hourglass-shaped women more appealing. Even from ancient times, women with larger, curvier hips have been associated with fertility, and so, strictly […]
