A study found that parents typically focus on negative aspects of sex, while peers promote positive messages. Parents are strongest supporters of abstinence and provide information on pregnancy and fertilization, but fail to discuss other topics. Peers encourage non-relational sex and promote sexual freedom, while the media reinforces ...
A recent survey of over 250,000 people from around the world has shed light on sex differences in brain function and behavior. The study found that men and women exhibit distinct patterns in mental abilities, with men scoring higher in visual-spatial tasks but women excelling in object location memory.
Conservation efforts in US and Mexico may be increasing loggerhead and Kemp's ridley turtles visiting UK waters. The research team attributes the increase to protective measures, such as turtle excluder devices in fishing nets.
A new study by Dr. Carmelia Suleiman explores the role of gender in media interviews with politicians Bill and Hillary Clinton. Researchers found that language choices and habits in conversation were influenced more by the interviewers' perspectives than the interviewees' genders.
A new study reveals that homing pigeons have a complex three-dimensional pattern in the sensory dendrites of their beak skin that reacts to the Earth's magnetic field vector. This allows them to identify their geographical position without relying on visual cues.
A study by Akiko Matsumoto-Oda found that female chimpanzees do not synchronize their reproductive activities, reducing opportunities for less-desirable males to coerce them into mating. This strategy allows females to mate with higher-ranking males who possess desirable social and physical characteristics.
The James Webb Space Telescope will enable fundamental breakthroughs in our understanding of the formation and evolution of galaxies, stars, and planetary systems. The telescope will complement and extend the discoveries of the Hubble Space Telescope with longer wavelength coverage and greatly improved sensitivity.
A study by Nives Dolsak and Maureen Dunn finds that developed countries invest in developing countries' greenhouse gas emission-reduction projects mainly due to economic reasons, such as reducing air pollution and transaction costs. The authors suggest policy makers to consider regional pollution dynamics when designing international r...
Researchers found that blue-eyed men rate blue-eyed female models as more attractive than brown-eyed models. In a second study, blue-eyed men were more likely to have romantic partners of the same eye color.
Research by Markus Neuhäuser and Sven Krackow found that the number and age of existing siblings significantly influence Down Syndrome risk. The study suggests that older mothers with a larger gap between pregnancies are more likely to have children with developmental defects.
Research by S. Kankova and colleagues found that Toxoplasma positive mothers give birth to more boys than negative women, with a probability of up to 72 boys in every 100 children born. The increased survival of male embryos may be attributed to the parasite's modulating effects on the immune system.
A new supplement provides essential information on preconception care, emphasizing the importance of women's health before pregnancy. The supplement covers topics such as folic acid supplements, vaccinations, and screening for HIV, as well as measures to avoid harmful substances like alcohol and anti-epileptic drugs.
Andrei Okounkov, Terence Tao and Wendelin Werner are honored with the Fields Medal for their work in probability, representation theory and algebraic geometry. Their contributions have brought new insights into problems in physics and mathematics.
A recent study published in Policy Sciences examines the ethnic differences in job quality among US forest workers. The research reveals that Hispanic workers face more onerous jobs with fewer benefits, including less job security and no health insurance compared to white workers.
A new study suggests injecting sulfur into the stratosphere could cool the planet by reflecting solar radiation. This method, known as albedo enhancement, has been observed during volcanic eruptions and could start taking effect within six months.
Springer presents a $1.04 million donation of more than 10,000 eBooks to seven New Orleans-area universities, enhancing their library resources and supporting research activities affected by Hurricane Katrina.
Researchers found that goalkeepers are unable to accurately predict the trajectory of a spinning football, relying on the ball's current heading direction. The study suggests that inherent limitations in the human visual system hinder this ability.
Researchers have deciphered engineering principles of biological nanosystems to develop new technologies, including assembly lines for cargo at the nanoscale level. This breakthrough promises novel ways to combat bacterial infections and interact with synthetic surfaces.
Martin Bengtsson, a young Swedish physicist, has been awarded the first Best Paper Award by the Analytical and Bioanalytical Chemistry Journal. His paper introduces a method to decrease laminar flow in microchannels without adding moving parts, which could become an important tool in microreactor technology.
