Study sheds new light on disease-spreading mosquitoes

When the West Nile virus (WNV) was initially isolated in two patients at a Queens, N.Y., hospital in the summer of 1999, it would have been hard to anticipate how quickly one common species of house mosquito, Culex pipiens, would help begin to spread the virus throughout the western hemisphere.

Blood-suckers carrying malaria parasites can be traced back up to 100 million years

The microorganisms that cause malaria, leishmaniasis and a variety of other illnesses today can be traced back at least to the time of dinosaurs, a study of amber-preserved blood-sucking insects and ticks show.

Starved ticks try harder to find hosts

Ticks are hardy little brutes that can go as long as a year without a meal. Now scientists at the University of Cincinnati say the hungrier ticks are, the harder they try to find you or other hosts. The findings could have implications for the spread of tick-borne disease such as Lyme or Rocky Mountain Spotted Fever.

Storage failures of eggs and embryos gain a new perspective

On March 3, 2018, a liquid nitrogen storage tank at the University Hospitals Fertility Center in Cleveland failed. Dr. Eli Adashi, a professor of medical science at Brown University's Warren Alpert Medical School, characterized the event as a "tragic accident" in which 950 patients lost more than 4,000 frozen eggs and embryos.

Disrupting reproduction strategy of disease-causing parasites could help fight malaria

Malaria parasites know good times from bad and plan their offspring accordingly, scientists have found, in a development that could inform new treatments.

Small-stature in rainforest populations may be linked to cardiac adaptations

African and Asian rainforest hunter-gatherers share short stature, and now an international team of researchers has shown that this is an example of convergent adaptation that may also be linked to changes in cardiac development pathways.

Infant girls fed soy formula more likely to develop severe menstrual pain as adults, suggests research

New research suggests that infant girls fed soy formula are more likely to develop severe menstrual pain as young adults. The finding adds to the growing body of literature that suggests exposure to soy formula during early life may have detrimental effects on the reproductive system. The study appears online in the journal Human Reproduction.

Aging edible dormice found to shorten hibernation for increase in reproductive activity

Edible dormice are extremely long-lived for their size thanks to their seasonal dormancy. The animals are veritable record holders in this "discipline", with hibernation periods lasting between at least six and a maximum of eleven months.

Study sheds new light on evolution of olfactory systems in vertebrates

In all animals, including humans, smell - the oldest of the five senses - plays a predominant role in many behaviors essential for survival and reproduction. It has been known since ancient times that animals react to odors.

Novel test measures male fertility

At a time when more than half of male infertility cannot be explained by current methods, a new test developed by Androvia LifeSciences is able to measure male fertility.

Innovative strategy opens up new avenue of treatment for anthrax infections

A team led by Professor Arne Skerra at the Technical University of Munich has developed an innovative strategy for preventing the anthrax bacterium from absorbing iron, which is crucial for its survival.

Environment impact of microplastics remains unclear

Scientists say there is not yet enough evidence to conclude that microplastics do or do not cause harm to the environment, following a review of more than 300 global studies.

Males who spend more time taking care of kids have greater reproductive success

Males have greater reproductive success if they spend more time taking care of kids -- and not necessarily only their own, according to new research published by anthropologists at Northwestern University.

Study: Neurons regulating reproductive hormone release have different activity in epileptic mice

Mice with epilepsy have altered patterns of neuron activity in the portion of the brain that controls the reproductive endocrine system, University of Illinois researchers report in a new study. Furthermore, the differences in neuron activity in female mice fluctuate across the reproductive cycle, the team found.
