Detrimental effect of tetracycline on male reproductive function, sperm viability of pseudoscorpions

In a paper published today in Nature's open access journal Scientific Reports, researchers at the University of Nevada, Reno report that male pseudoscorpions treated with the antibiotic tetracycline suffer significantly reduced sperm viability and pass this toxic effect on to their untreated sons. They suggest that a similar effect could occur in humans and other species.

Study finds negative health effects of anti-depressants

Commonly prescribed anti-depressants appear to be doing patients more harm than good, say researchers who have published a paper examining the impact of the medications on the entire body.

Cosmetics may contain chemicals that raise risk of obesity and diabetes

Scientists found that those who were exposed to phthalates, colourless man-made substances included in a variety of common consumer products, were more prone to weight gain. And subjects with even 'modest' levels of the substance in their bloodstream were twice as likely to develop diabetes.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.

New technique could restore fertility of boys undergoing cancer treatment

Treatments for childhood cancers are increasingly successful with cure rates approaching 80%, but success often comes with a downside for the surviving men: the cancer treatments they received as boys can leave them sterile as adults. Now, a research team led by Ralph Brinster of the University of Pennsylvania School of Veterinary Medicine has completed a 14-year experiment that gives hope for a technique that could restore their fertility.

UC Riverside to study molecular basis of hormonal regulation of mosquito reproduction

Female mosquitoes require energy for their egg development, which they acquire from vertebrate blood. But by sucking on blood, they become vectors of numerous disease pathogens of human and domestic animals. If the mechanisms that govern their egg production are better understood, novel approaches to controlling the reproduction and population of mosquitoes can be devised.

Cardiff team receives European grants to develop 'RealTCut' surgical simulation

Highly realistic surgical simulation which reduces patient risk has become the 100th Cardiff University project to win an award under the European Union's prime research funding scheme, the Seventh Framework Programme.

BPA alters uterus structure leading to potentially fatal infection

Researchers at the University of Cincinnati (UC) have found evidence that, in addition to affecting the heart, brain and nervous system, bisphenol A (BPA), could affect a mammal's ability to reproduce by altering the structure of the uterus in ways that can progress to a potentially fatal infection.

New book on reproductive treatments

In Vitro Fertilization [IVF] and the related technologies of assisted reproduction are no longer experimental procedures. In some European countries as many as 4% of all babies born are conceived by IVF, and in every kindergarten classroom there will no doubt be at least one IVF child. Assisted reproduction is the solution to today's epidemic of infertility.

Silver nanoparticles cause more damage to testicular cells

Silver nanoparticles cause more damage to testicular cells than titanium dioxide nanoparticles, according to a recent study by the Norwegian Institute of Public Health. However, the use of both types may affect testicular cells with possible consequences for fertility.

Virginia uproar frames abortion, contraception legislation in many states

States are grappling with reproduction-related issues after Virginia's pre-abortion ultrasound bill passed: In California, lawmakers are set to consider a bill to give more women access to early-term abortions while lawmakers in Ohio and Minnesota consider legislation on contraception.

Flat worms may hold key to immortality

Experts from Nottingham University created a colony of more than 20,000 flatworms from one original by chopping it into pieces and observing each section grow into a new complete worm. They believe that it could help scientists develop new methods to allow humans to stay younger for longer.

La Selva geothermal system contaminated with arsenic

Monitoring the construction of wells, avoid over-exploiting cold groundwater close to hot groundwater, and controlling mineral water extraction. These are the recommendations from the Polytechnic University of Catalonia and the University of Barcelona, after analysing the contamination of La Selva geothermal system, above all by arsenic pollution.

CU professor to interview epilepsy sufferers and their families in depth

Sara Shostak, assistant professor in the department of sociology, along with principal investigator Ruth Ottman, professor of epidemiology at Columbia University, and other collaborators were recently awarded a $2 million grant from The National Institute of Neurological Disorders and Stroke (NINDS) to learn more about these questions.

Scientists discover that sperm do not function like olfactory cells

According to a 2003 study by German and American scientists, a component of the Lily of the Valley scent known as Bourgeonal alters the calcium balance of human sperm and attracts the sperm. The "Lily of the Valley phenomenon" - also the title of a book about smelling - was born as a result of this discovery that sperm act as swimming olfactory cells which follow a "scent trail" laid by the egg. However, a detailed explanation for the Lily of the Valley phenomenon remained illusive as neither Bourgeonal nor other scents could be identified in the female sex organ.
