Holograms Offer Hope In Fight Against Malaria
2013-11-06 08:56:44

University of Edinburgh Scientists have developed a 3D filming technique that could help inform research to stem the spread of malaria. Creating moving digital holograms of malaria sperm has given researchers fresh insights into the behavior of these tiny life forms. Understanding how malaria parasites mate could pave the way for improved prevention and control of this deadly disease, which poses a threat to half of the world's population. Malaria parasites mate in the gut of...

Researchers awarded National Science Foundation grant to develop new device that identifies healthy sperm cells, potentially helping couples to conceive. Worcester, MA (PRWEB) October 30, 2013 The World Health Organization estimates more than 70 million couples worldwide are unable to conceive each year, with close to a third of those cases attributable solely to issues with male fertility—including low sperm count and low sperm motility (a limited ability to swim). Now, with recently...

Role Of Sperm Competition In Formation Of New Species Confirmed By Biologists
2013-09-27 08:09:16

Syracuse University 'Current Biology' article marks culmination of 6 years of research Female promiscuity—something that occurs in a majority of species, including humans—results in the ejaculates from two or more males overlapping within her reproductive tract. When this happens, sperm compete for fertilization of the female's eggs. In addition, the female has the opportunity to bias fertilization of her eggs in favor of one male's sperm over others. These processes,...

Females play a larger role in determining paternity than previously thought, say biologists in Syracuse University's College of Arts and Sciences. Their findings are the subject of a new paper titled "Female mediation of competitive fertilization success in Drosophila melanogaster," published this month by Proceedings of the National Academy of Sciences of the United States of America. Stefan Lüpold, a research assistant professor in the college's Department of Biology and...

Sperm cell release can be triggered by tightening the grip around the delivery organ, according to a team of nano and microsystems engineers and plant biologists at the University of Montreal and Concordia University. Concordia's nanobiotech team devised a microchip that enabled the University of Montreal biologists to observe what happened when pollen tubes — the sperm delivery tools used by plants — tried to negotiate a microscopic obstacle course. The pollen tubes were exposed...

Hyper And Micro-gravity Affect Processes Involved In Reproduction, Brain Diseases And Cancer
2013-03-14 12:12:58

University of Montreal University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular "highways" that ensure the growth and functionality of the male reproductive organ in plants, the pollen tube. "Just like during human reproduction, the sperm cells in plants are delivered to the egg by a cylindrical tool. Unlike the delivery tool in animals, the device used during plant sex consists of a single...

Gooseneck Barnacles Have The Biggest Penises
2013-01-16 19:20:59

Lee Rannals for redOrbit.com — Your Universe Online While some strive with “male enhancement” pills to increase the size of their manhood, they will never live up to the reputation of the barnacle, which have the largest penises relative to body size. Imagine a redwood tree, sitting on a small rock in a field, then you have the proper outlook on what the sea-dwelling creatures have on you. New research indicates that the well-endowed gooseneck barnacles are able to...

Sperm Count, Quality In Men Lower Now Than Two Decades Ago
2012-12-05 12:26:58

Lawrence LeBlond for redOrbit.com - Your Universe Online Male fertility is one of the most controversial issues in medical science. Recent studies have shown that some chemicals can harm male fertility while others have shown foods that actually boost it. Despite all the science, it seems sperm counts in men are dropping all around the world. And no place seems more threatened by sperm loss than France. In a new study reported in the journal Human Reproduction, French researchers have...
