During sex with a familiar partner, men have the highest orgasm rates - though lesbian women apparently don't do too badly.

On average, men experience orgasm 85.1 percent of the time, with only slight deviation by sexual orientation but women experience orgasm 62.9 percent of the time, with lesbian women experiencing orgasm more often than heterosexual or bisexual women, according to a new paper about a survey of American singles titled "Variation in Orgasm Occurrence by Sexual Orientation in a Sample of U.S. Singles" and published in the Journal of Sexual Medicine.

People allergic to milk often assume they have lactose intolerance, but they are actually different mechanisms that occur in different parts of the body. 

People with lactose intolerance do not digest lactose properly because they lack an enzyme known as lactase - and that results in digestive discomfort.  A cow milk allergy is much more dangerous because the body's immune system attacks milk proteins with its own IgE antibodies. 

A comprehensive study of rhino reproduction over six years encompassed 90% of the European population of captive black rhinos in Europe highlights and finds that hormone analysis could improve the success of breeding programs.

In total, 9,743 samples from 11 zoos were sent to Chester Zoo's Wildlife Endocrinology laboratory to analyze female reproductive cycles.

It's a smartphone world; a decade ago a crowded train of passengers all locked into their phones texting to other people while ignoring the live humans six inches from them was just xenophobic Japanese culture but today it is common all across the developed world.

Psychologists worry that children getting meaning and context spoon-fed to them with emoticons may be leading to poor social skills in the real world, and even an inability to read emotions.

UCLA psychologists found that sixth-graders who went five days without even glancing at a smartphone, television or other digital screen did substantially better at reading human emotions than sixth-graders from the same school who spent more time looking at electronic devices.

New research may help to solve the mystery of what caused a spectacular supernova in galaxy M82 11 million light years away.

The supernova, a giant explosion of a star and the closest one to the Earth in decades, was discovered earlier this year and new research into its cause used vast networks of radio telescopes in the UK and across Europe including the seven telescopes of e-MERLIN operated from The University of Manchester's Jodrell Bank Observatory. These enabled them to obtain extremely deep images revealing a lack of radio emission from the supernova.

A volunteer group of citizen scientists set up to safeguard communities around the 'Throat of Fire' Tungurahua volcano in the Ecuadorian Andes is saving lives, according to a new paper.
