Gene linked to autism in families with more than one affected child
A version of a gene has been linked to autism in families that have more than one child with the disorder. Inheriting two copies of this version more than doubled a child's risk of developing an autism spectrum disorder. view more (2006-10-18)
Study shows aggressive students often lack psychological evaluations and effective treatment
As the disturbing trend of school violence continues to plague our education system, it is important for caregivers, educators, and doctors to join forces to be proactive in its prevention. view more (2006-08-25)
Landmark study sheds new light on human chromosomal birth defects
Using yeast genetics and a novel scheme to selectively remove a single protein from the cell division process called meiosis, a cell biologist at The Florida State University found that when a key molecular player known as Pds5 goes missing, chromosomes fail to segregate and pair up properly, and birth defects such as Down syndrome can result. view more (2009-09-17)
Rise in ICSI cycles suggests infertility could be affecting more men than women
Infertility may be becoming more of a man's problem than a woman's problem according to new figures released at the 21st annual conference of the European Society of Human Reproduction and Embryology. view more (2005-06-22)
Neandertals, humans share key changes to 'language gene'
A new study published online on October 18th in Current Biology reveals that adaptive changes in a human gene involved in speech and language were shared by our closest extinct relatives, the Neandertals. view more (2007-10-19)
Mothers transmit DNA through daughters only
Scientists have argued whether or not the often-studied mitochondrial DNA molecule is clonally inherited. It is with assuming clonal inheritance this type of DNA has been used to track the origin of modern human as well as to draw pictures of genetic relationships among other animals and plants. The conflict has now been solved by two evolutionary... view more... (2001-09-06)
Workshop Suggests Turning Problems into Biofuels
The twin problems of too much feedlot manure and too many mesquite trees could be solved by converting them into renewable bioenergy products, Texas A&M University System agricultural researchers, engineers and commercialization experts suggested Friday. view more (2006-09-05)
Scientists endure Arctic for last campaign prior to CryoSat-2 launch
An international group of scientists has swapped their comfortable offices for one of the most inhospitable environments on the planet to carry out a challenging field campaign that is seen as the key to ensuring the data delivered by ESA's ice mission CryoSat will be as accurate as possible. view more (2008-05-12)
Synchronized swimming of algae
Using high-speed cinematography, scientists at Cambridge University have discovered that individual algal cells can regulate the beating of their flagella in and out of synchrony in a manner that controls their swimming trajectories. view more (2009-07-24)
Radio telescope images reveal planet-forming disk orbiting twin suns
Astronomers are announcing today that a sequence of images collected with the Smithsonian's Submillimeter Array (SMA) clearly reveals the presence of a rotating molecular disk orbiting the young binary star system V4046 Sagittarii. view more (2009-06-11)
NARVAL — The first observatory dedicated to stellar magnetism
NARVAL, a stellar spectropolarimeter, has recently been installed on the 2 meter diameter Bernard Lyot Telescope (INSU-CNRS) at the summit of the Pic du Midi in the French Pyrenees. view more (2007-02-09)
Rosetta all set for Mars swing-by
Rosetta, the European Space Agency's (ESA) spacecraft en route to comet 67P Churyumov Gerasimenko, is gearing up for a swing-by of Mars on 25th February 2007, which will help set it on the correct path to its final destination. view more (2007-02-20)
Invasive species on the march: variable rates of spread set current limits to predictability
Whether for introduced muskrats in Europe or oak trees in the United Kingdom, zebra mussels in United States lakes or agricultural pests around the world, scientists have tried to find new ways of controlling invasive species by learning how these animals and plants take over in new environs. view more (2009-09-18)
The host makes all the difference
"Where there are many scientific works dealing solely with the flu virus, we have investigated how the host reacts to an infection," says Klaus Schughart, head of the Experimental Mouse Genetics research group. view more (2009-03-27)
First Case Of Variant CJD In Italy
A research letter in this week's issue of THE LANCET describes the first case of variant Creutzfeldt-Jakob disease (vCJD) in Italy. Up to May 2002 there have been 126 cases of vCJD reported in the UK, France, and Ireland. The woman, aged 25 years was admitted to hospital last November. She had never travelled to any of these countries, and had... view more... (2002-09-25)
Nurses wash their hands more often than doctors
Nurses are more conscientious handwashers than doctors, finds a study in this week's Christmas issue of the BMJ. Hand washing is a quick, cheap and easy way of preventing the spread of infection. Identical soap dispensers were installed next to the sinks in the consulting room of each member of a primary care surgery in Cardiff (two nurses and... view more... (2003-12-17)
A master mechanism for regeneration?
Biologists long have marveled at the ability of some animals to re-grow lost body parts. Newts, for example, can lose a leg and grow a new one identical to the original. Zebrafish can re-grow fins. view more (2009-10-20)
An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon the balance between nutrient benefits and carbon... view more... (2003-05-22)
Europe's healthcare systems supports trend for quality and quantity in ART
Madrid, Spain: Europe's systems for healthcare are generally more able to support couples seeking fertility treatment than anywhere else in the world, experts will tell the annual meeting of the European Society of Human Reproduction and Embryology today (Wednesday, 2 July). view more (2003-07-01)
A brand new Microcar
The basque technological centre TEKNIKER has developed a brand new microcar to test all its capabilities in the micromanufacture. It is driven by an electric motor, the smallest in the market with an external diameter of 1.9 mm and longitude of 5 mm, a stator coil wound with 30 µm diameter wire and a rotor with permanent magnets. This micromotor... view more... (2004-07-29)
