UK researchers have shown a strong direct relationship between ovarian volume and the number of primordial follicles (eggs) remaining in the ovaries of women of reproductive age. The measurement of ovarian volume by transvaginal ultrasound will enable an accurate prediction of the age of menopause and hence a woman’s reproductive age.
They say that the possibility of making an accurate assessment of ovarian reserve will revolutionize the care of women seeking assisted conception, those
Finding could yield new insight into the Neurobiology of romantic love and the inability to form social bonds
Researchers at the Yerkes National Primate Research Center of Emory University and Atlanta’s Center for Behavioral Neuroscience (CBN) have found transferring a single gene, the vasopressin receptor, into the brain’s reward center makes a promiscuous male meadow vole monogamous. This finding, which appears in the June 17 issue of Nature, may help better explain the ne
Speed is the name of the game in the world of racing and now UCL scientists have developed a technique that ’breeds’ winning Formula One cars.
By applying Darwinian principles to the art of motor racing, the researchers demonstrate in simulations that it’s possible to knock crucial tenths of a second off lap time by tailoring a car’s setup to whatever conditions are faced on the track.
In a paper to be presented later this month at a conference in Seattle, rese
Patients with acute myeloid leukemia (AML) who enter remission with abnormal chromosomes in bone marrow cells are twice as vulnerable to recurrence of their disease as are AML patients with normal bone marrow cells at remission, according to a new study.
The findings by researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute call for routine testing for chromosomal abnormalities in AML patients at diagno
When he wasn’t experimenting with lightning or overthrowing the British Empire, Benjamin Franklin found time to fool around with mathematics, inventing a variant of the magic square called Franklin’s squares. Now Maya Ahmed, a mathematics graduate student at UC Davis, has come up with a way to construct both Franklin’s own squares and others of the same type. The methods could have applications in computer programming for business.
A regular magic square is a table of numbers in which any
After a quiet, six-and-a-half-year, 2.2-billion-mile journey to Saturn aboard NASA’s Cassini spacecraft, the University of Chicago’s dust detector will soon begin its attempt to help unravel the mystery of the planet’s legendary rings one tiny particle at a time.
Cassini will become the first spacecraft ever to enter Saturn’s orbit at precisely 9:30 p.m. CDT June 30. NASA launched Cassini in October 1997. The University’s instrument, called the High Rate Detector, has quietly recorded spora
José María Mato is a scientist at the new CIC-Biogune research centre in Zamudio (Bizkaia). For more than twenty years now he has been studying the liver disease known as steatohepatitis. This is a serious illness which develops when large amounts of fat are accumulate din the liver, and mat result in cirrhosis or, in the worst scenario, in cancerous tumours.
The greatest problem with this illness to date is that it cannot be diagnosed until the symptoms have already appeared and then it is
Developing a bioinsecticide that is more effective than pesticides for controlling pests in greenhouses is the aim of the project undertaken by a research team from the Public University of Navarre and commissioned by the Almería Fruit & Vegetable Exporters Association (COEXPHAL).
Biological efficiaciousness
The COEXPHAL Association of the province of Almería manages a surface area of about 18,000 hectares, primarily given over to greenhouse vegetables. Many of these crops (
Optimising and standardising trials on the resistance of orchard fruit to the harvesting and picking processes, increasingly used to determine quality, was the aim of the PhD presented by Martín Sanmartín Goñi at the en Public University of Navarre.
Handling and conservation
The harvesting, transport and conservation of fruit and garden produce is currently carried out mechanically. In these processes of product handling, they can be subject to bangs, vibrations and crushi
Unusual happenings at Dundrum Bay, County Down, have been puzzling residents for some time now. Reports of the beach at Newcastle disappearing while sand dunes at Ballykinler, across the bay, were getting bigger and bigger, had locals and Down County Council stumped.
But researchers from the University of Ulster have stepped in to explain the mysterious phenomenon.
Dr Andrew Cooper and Dr Fatima Navas, from the Centre for Coastal and Marine Research at UU, have discovered that nat
University of Ulster research probes pals’ influences on Northern Ireland prejudice levels.
Just having a friend who has a friend from the ‘other side’ can reduce levels of sectarian prejudice among individuals in Northern Ireland, according to new psychological research from the University of Ulster.
This research was carried out in the context of inter-community relations in Northern Ireland. In two surveys, one with over 300 university students and the other with over 70
Under the EU Sixth Framework Programme (FP6) for Research and Development (2002-2006) 2.2 million Euros have been awarded to the 3DGENOME-research program. FP6 is one of the world’s largest research programmes, with a budget of 17.5 billion Euros, of which around 3 billion Euros is available for life sciences research. The main objective of the 3DGENOME program is to understand how the human genome, consisting of a number of very long DNA molecules that carry our genetic information, are coiled
Long term relief for arthritis sufferers could be one step closer, thanks to a study of B-cell targeted therapy published today. The study from UCL reveals a major but hitherto poorly acknowledged role for B-cells in the most common and severe form of arthritis to affect younger people. By targeting B-cells, which are part of the body’s immune system, it may be possible to break a key vicious cycle underlying the disease.
The drug trial, led by UCL Professor Jonathan Edwards, published toda
Graphics Breakthrough Can Benefit Cartoon and Game Creators, Web Marketers, Virtual Museums and Others
A University of Southern California computer scientist has created a powerful and elegant algorithm to compress the large and ungainly files that represent 3-D shapes used in animations, video games and other computer graphics applications.
Mathieu Desbrun, assistant professor of computer science at the USC Viterbi School of Engineering says that digital sound, pictures and vide
Study of major significance unlocks the door to the complex role of how hormones work in women and demonstrates steep decline of hormones in early reproductive years.
Findings from the Australian based Jean Hailes Foundation will be presented this week at the Endocrine Society’s 86th Annual Meeting that establish normal hormone levels in women across the life span.
This definitive study is part of the Sue Ismiel International Study into Women’s Health and Hormones, involving 1
Soybean crops planted weeks ago appear in no hurry to grow. Others aren’t turning a rich green in color. And while growers might be starting to worry, there’s no need to fret, said Ellsworth Christmas, Purdue University Extension soybean specialist.
“There are two basic questions producers have at this time,” Christmas said. “No. 1, why are soybeans that have emerged growing so slowly? And, secondly, why are the plants yellow or very light green in color? Both of those concerns are
