Mother knows best
Scientists have found new evidence to explain how female insects can influence the father of their offspring, even after mating with up to ten males. view more (2009-09-09)
Daily sex helps to reduce sperm DNA damage and improve fertility
Daily sex (or ejaculating daily) for seven days improves men's sperm quality by reducing the amount of DNA damage. view more (2009-06-30)
Evolutionary phenomenon in mice may explain human infertility
Scientists at the University of Liverpool have found that field mice have evolved a unique way of ensuring faster fertilisation, a phenomenon which could explain some cases of infertility in humans. view more (2008-01-23)
New study finds most North Pacific humpback whale populations rebounding
The number of humpback whales in the North Pacific Ocean has increased since international and federal protections were enacted in the 1960s and 70s, according to a new study funded primarily by NOAA and conducted by more than 400 whale researchers throughout the Pacific region. view more (2008-05-22)
A test to prove a woman has been raped
Stray Y chromosomes can confirm an allegation of rape A TEST that can prove a woman has been raped even if no sperm are found should be widely adopted, the first large-scale study suggests. After the trauma of rape, women who report it have to undergo a medical examination to look for sperm. But the... view more... (2002-02-27)
Mama whales teach babies where to eat
University of Utah biologists discovered that young "right whales" learn from their mothers where to eat, raising concern about their ability to find new places to feed if Earth's changing climate disrupts their traditional dining areas. view more (2009-02-09)
UVa Scientists Discover New Human Protein Offering Clue To Immune Infertility in Men and Women
Most of us have never heard of immune infertility, yet it prevents many prospective parents from conceiving. view more (2007-09-13)
Russian-American research team examines origins of whaling culture
Recent findings by a Russian-American research team suggest that prehistoric cultures were hunting whales at least 3,000 years ago, 1,000 years earlier than was previously known. view more (2008-04-07)
A new male-specific gene in algae unveils an origin of male and female
By studying the genetics of two closely related species of green algae that practice different forms of sexual reproduction, researchers have shed light on one route by which evolution gave rise to reproduction though the joining of distinct sperm and egg cells. view more (2006-12-19)
Monitoring Baleen Whales with Autonomous Underwater Vehicles
Like robots of the deep, autonomous underwater vehicles, or AUVs, are growing in number and use in the oceans to perform scientific missions ranging from monitoring climate change to mapping the deep sea floor and surveying ancient shipwrecks. view more (2006-02-22)
Early-stage sperm cells created from human bone marrow
Human bone marrow has been used to create early-stage sperm cells for the first time, a scientific step forward that will help researchers understand more about how sperm cells are created. view more (2007-04-13)
Chromosomal abnormalities in sperm higher after vasectomy reversal
Men who have had a vasectomy reversed have a very much greater rate of chromosomal abnormalities in their sperm than do normal fertile men. view more (2006-06-21)
Is there a risk of transmitting genetic disorders to babies conceived by fertility procedures?
As medical technology continues to advance, fertility procedures such as in-vitro fertilization and donor insemination are becoming more commonplace. view more (2006-05-22)
How is that whale listening?
Researchers from San Diego State University and the University of California have been using computer models to mimic the effects of underwater noise on an unusual whale species and have discovered a new pathway for sound entering the head and ears. view more (2008-02-04)
Unlocking the key to human fertility
Scientists at Leeds and Bradford have discovered a unique 'DNA signature' in human sperm, which may act as a key that unlocks an egg's fertility and triggers new life. view more (2009-08-03)
Dolphins get a lift from delta wing technology
We can only marvel at the way that dolphins, whales and porpoises scythe through water. Their finlike flippers seem perfectly adapted for maximum aquatic agility. view more (2009-06-26)
Human sperm created from embryonic stem cells
Human sperm have been created using embryonic stem cells for the first time in a scientific development which will lead researchers to a better understanding of the causes of infertility. view more (2009-07-08)
Whales Are More Precious Than Oil
WWF and the International Fund for Animal Welfare (IFAW) published results of scientific assessment of the "Sakhalin-2" oil and gas project's (Sakhalin Energy company) impact on the Okhotsk-Korean population of grey whales. The findings are distressing: if only three females perish, this grey whale (Eschrichtius robustus) population will... view more... (2005-03-14)
Possible Genetic Factor for Male Infertility Identified
Virginia Commonwealth University School of Medicine researchers have discovered a gene involved with the production of sperm that may contribute to male infertility and lead to new approaches to male contraception. view more (2009-09-16)
Endangered right whales found where presumed extinct
Using a system of underwater hydrophones that can record sounds from hundreds of miles away, a team of scientists from Oregon State University and the National Oceanic and Atmospheric Administration has documented the presence of endangered North Atlantic right whales in an area they were thought to be extinct. view more (2009-05-21)
