Research by Hungarian fertility experts published on Thursday 10 June in Europe’s leading reproductive medicine journal Human Reproduction, has revealed that the onset of the menopause may not be dictated only by the fact that a woman’s lifetime supply of eggs are running low, but also by changes in the seasons.
Analysis of reliable questionnaires from over 100 patients at the menopause clinic at Baranya County Teaching Hospital in Pécs, revealed that the spring and autumn equinoxes played a
US research published on Thursday 10 June in Europe’s leading reproductive medicine journal Human Reproduction[1] suggests that a single act of unprotected intercourse is more likely to lead to an unwanted pregnancy than was previously believed.
In a study on women who had either been sterilised or were using an intrauterine device (IUD) the frequency of intercourse increased during the six most fertile days of the menstrual cycle and peaked at ovulation ¨C despite the fact that these
Secrets of the Earth’s past climate locked in a three-kilometre long Antarctic ice core are revealed this week in the journal Nature. The core from Dome C, high on East Antarctica’s plateau, contains snowfall from the last 740,000 years and is by far the oldest continuous climate record obtained from ice cores so far.
The ice has been collected in an eight year project by scientists and engineers from 10 European countries. Analysis of ice cores shows how temperature changed in the past, b
Symptoms experienced by women that are more severe or frequent than expected and of recent occurrence warrant further diagnostic investigation because they are more likely to be associated with both benign (non-cancerous) and malignant (cancerous) ovarian masses, according to a study in the June 9 issue of The Journal of the American Medical Association (JAMA).
“Ovarian cancer has often been called the ‘silent killer’ because symptoms are not thought to develop until advanced stages when cha
More traffic, more incidents; an urban traffic manager’s nightmare. Yet tried and tested solutions to predict, detect, verify, and respond to such incidents are a dream come true.
The solutions were the result of research undertaken by the IST programme-funded PRIME project. The objective of PRIME, an acronym for Prediction of Congestion and Incidents In Real Time for Intelligent Incident Management and Emergency Traffic Management, was to develop innovative methods to improve the dyna
With numerous European companies caught in a dilemma of growing technology demands and shrinking IT budgets, outsourcing software development to Russia and the Newly Independent States (NIS) is an increasing attractive option.
ADONIS, an IST programme-funded project, is meeting the challenges of this dilemma by assisting European organisations and businesses to outsource software development in collaboration with programmers in Russia and the NIS of the former Soviet Union, primarily Ukrain
Heat turns colonial algae into hotties.
When algae find themselves in hot water, the normally asexual organisms get all stressed out and turn sexual.
Blame it on the free radicals, says a team of researchers.
Colonies of the multicellular green alga Volvox carteri exposed to temperatures of 111 degrees Fahrenheit (42.5 degrees Celsius) had twice the amount of free radicals, oxidants that can damage biological structures, as unheated colonies. High levels of oxidan
Findings may help point researchers toward future medical treatments
Mayo Clinic researchers report in the latest issue of Mayo Clinic Proceedings that there may be an association between lower urinary tract symptoms and sexual dysfunction among older men. As the population ages, this finding will help further research that could help millions of men.
Lower urinary tract symptoms become common as men age and their prostates enlarge, restricting urine flow or altering their b
Unwanted, pulled or poisoned, the lowly weed is sometimes better than its highly touted “herbal” cousins for preventing and curing a host of diseases, according to University of Florida research.
“If I had one place to go to find medicinal plants, it wouldn’t be the forest,” said John Richard Stepp, a UF anthropologist who did the study. “There are probably hundreds of weeds growing right outside people’s doors they could use.”
Stepp combed through scientific journals an
Plant pathologists present research on food safety at APS Annual Meeting in Anaheim, California
Recent advances in food safety research are enabling plant pathologists to gain insight into how dangerous human pathogens, such as strains of E.coli and Salmonella, can survive on fresh fruits and vegetables and what can be done to control future outbreaks.
According to Steve Scheuerell, faculty research associate at Oregon State University’s Department of Botany and Plant P
Astrophysicists led by the University of Chicago’s Andrey Kravtsov have resolved an embarrassing contradiction between a favored theory of how galaxies form and what astronomers see in their telescopes.
Astrophysicists base their understanding of how galaxies form on an extension of the big bang theory called the cold dark matter theory. In this latter theory, small galaxies collide and merge, inducing bursts of star formation that create the different types of massive and bright galax
A Purdue University mathematician claims to have proven the Riemann hypothesis, often dubbed the greatest unsolved problem in mathematics.
Louis De Branges de Bourcia, or de Branges (de BRONZH) as he prefers to be called, has posted a 23-page paper detailing his attempt at a proof on his university Web page. While mathematicians ordinarily announce their work at formal conferences or in scientific journals, the spirited competition to prove the hypothesis – which carries a $1 million
Some slow, cold visitors stopped by Los Alamos National Laboratory last week, and their arrival could prove a godsend to physicists seeking a better theory of everything.
Researchers working at the University of California’s Los Alamos Neutron Science Center and eight other member institutions of an international collaboration took a giant step toward their goal of constructing the most intense source of ultra-cold neutrons in the world, measuring ultra-cold neutron production in
During their tender youth, both the endangered fish species totoaba and the commercially important gulf corvina require the brackish water habitat provided by the shrinking Colorado River estuary, report researchers.
Although overfishing has been implicated in the decline of both species, commercial harvesting isn’t the only reason for the two species’ decline, the finding suggests. Since 1960, diversion of Colorado River water for human uses has greatly reduced the amount of fresh water t
With Mars now high on the agenda for future space exploration, researchers around the world are building and testing systems that could support long and complex scientific missions to the red planet.
Inter-planetary expeditions will take place over many years and require robust communication systems between the astronauts on Mars and scientists on Earth. Remote Science Teams (RSTs), who specialise in fields such as geology, will be formed from experts around the globe to collaborate on analy
The UK is a tornado hotspot, according to University of Leeds researchers, who have found that more than 100 tornadoes a year hit the UK – more per acre than the rest of Europe and the US.
In a Quarterly Journal of the Royal Meteorological Society paper, geographers Joseph Holden and Amy Wright argue that although there are 20-30 sightings each year, five times that number of tornadoes actually hit the UK.
Most tornadoes are not reported because they are not seen. But by modelling t
