Study on kids and a career: Traditional role models still largely exist
A representative survey by IU International University of Applied Sciences reveals there are still significant differences between the sexes in career trajectories......»»
Battle of the sexes: Men and women like different iPhone models
Although there isn't much of an age difference in Apple device ownership, men and women prefer different iPhone models. Here's how they differ.Men tend to prefer iPhone ProsApple device ownership is mainly similar across various age groups, although.....»»
World"s heaviest flying bird may be self-medicating on plants used in traditional medicine
If you see a great bustard (Otis tarda) in the wild, you're unlikely to forget it. Massive, colorful, and impossible to mistake, they are the heaviest birds living today capable of flight, with the greatest size difference between the sexes. They are.....»»
Study: Women may have an edge in entrepreneurial success
Differences in the way the sexes think may give women an advantage in starting businesses, a study led by a Kennesaw State University researcher suggests......»»
Games of power: Scientists decode behavioral patterns of dominance between the sexes in mammals
The stronger and more aggressive sex dominates the weaker sex. This simplistic view of male-female dominance relationships is common but falls short of the complexity of how dominance hierarchies are established in animal societies......»»
Sex and power in the animal kingdom: Seven animals that will make you reconsider what you think you know
It's easy to assume all animals have a neat dividing line between the sexes because the differences in appearance between males and females can be so striking. But the more scientists learn about wildlife, the clearer it is that nature doesn't have a.....»»
Male spiders maximize sperm transfer to counter female cannibalism
When sexual conflict results in reproductive strategies that only benefit one of the sexes, it may result in evolutionary arms races. Male spiders have evolved behavioral mating strategies to improve their chances of mating despite the risk of being.....»»
New study shows that aging neutralizes sex differences in the brain
When male and female fruit flies age, their brains become desexualized. Age-related changes take place in both sexes, but the male brain becomes feminized to a larger extent than the female brain becomes masculinized. This is the conclusion of a stud.....»»
Cell map of human gonads identifies the cells involved in sex determination
The first large-scale cellular map of gonadal developmental in both sexes has been created by researchers at the Wellcome Sanger Institute, as part of the Human Cell Atlas initiative to map all cell types in the human body......»»
Digging is not just a game for children in hunter-gatherer groups
Ana Mateos and Jesús Rodríguez, scientists at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have published an experimental energy study in the journal Human Nature, using volunteers of both sexes aged 8 to 14, showing t.....»»
This Australian grasshopper gave up sex 250,000 years ago and it"s doing fine
Most animals on Earth have two sexes, male and female, that combine and mix their genes when they reproduce. We are so accustomed to this state of affairs that the existence of all-female species that don't have sex, but instead reproduce by cloning,.....»»
It"s a female bonobo"s world—ecologists propose new tools to assess sex and power among wild animals
In the wild, it might seem like male animals run the show. But in a review publishing in Trends in Ecology & Evolution on May 18, researchers lay a new framework to assess power distribution between the sexes, and its application shows that in some a.....»»
Wind turbines kill mostly female and juvenile bats
Many bats die at wind turbines when colliding with the spinning blades. Currently it is unclear whether all age cohorts or sexes are equally vulnerable. A comparison of age, sex and geographic origin of Nathusius' pipistrelles killed at wind turbines.....»»
Researchers identify key RNA "gatekeeper" in gene expression, pointing to possible new drug targets
An important player in the healthy development of female embryos turns out also to play a key role in regulating the behavior of chromosome loops and gene expression in both sexes, according to a new study by researchers at Massachusetts General Hosp.....»»
We used 60-year-old notebooks to find out why male hippos have bigger tusks than females
Male hippopotamuses are an unusual size. Among mammals, males are usually much larger than females, but in hippos the sexes have surprisingly similar sized bodies. All except the jaws and tusks, which are much bigger in males......»»
Researchers on quest to understand how different sexes first evolved
For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has traveled an hour west of Tokyo to visit the Sagami River and collect algal samples to understand how living things evolved different sexes. Through new analysis of samples col.....»»
Brain disease research reveals differences between sexes
Scientists highlight a growing body of research suggesting sex differences play roles in how patients respond to brain diseases, as well as multiple sclerosis, motor neuron disease, and other brain ailments. They are urging their colleagues to rememb.....»»
X marks the spot: How genes on the sex chromosomes are controlled
Because human females have two X chromosomes and males have one X and one Y, somatic cells have special mechanisms that keep expression levels of genes on the X chromosome the same between both sexes. This process is called dosage compensation and ha.....»»
