Mayo Clinic researchers discover that key cancer gene cbp doesn’t work alone; Important clue to targeting new treatments for lymphoma, breast and colon cancers
Mayo Clinic cancer researchers have discovered a key partnership between two genes in mice that prevents the development of cancer of the lymph nodes, known as T-cell leukemia or lymphoma.
This first-time finding provides researchers with a promising target for designing new anti-cancer drugs that fight lymphomas,
With the slim chance that farmers will stop planting crops containing genes from other organisms, researchers have started to develop strategies that trap these foreign genes, reducing the risk that they’ll spread to wild relatives.
But an investigation by scientists from the University of Wisconsin-Madison and the University of Minnesota-St. Paul shows that these containment strategies can quickly fail.
Using mathematical models, the team of scientists explored the effective
NSF ’sugar’ grant supports single-chamber prototype fed by wastewater
Something big may be brewing on the sewage treatment circuit thanks to a new design that puts bacteria on double-duty-treating wastewater and generating electricity at the same time.
The key is an innovative, single-chambered microbial fuel cell. The prototype is described in the online version of the journal Environmental Science & Technology (http://pubs.acs.org/journals/esthag/); the article w
Before humans can leave their boot prints on the dusty surface of Mars, many questions have to be answered and many problems solved. One of the most fundamental questions – one that has intrigued humankind for centuries – is whether life has ever existed on Mars, the most Earthlike of all the planets.
Through its long-term Aurora Programme of solar system exploration, ESA is already preparing a series of robotic missions that will reveal the Red Planet’s secrets and pave the way for a human
On 26 February, Rosetta will be setting off on its long journey through our solar system to meet up with Comet Churyumov-Gerasimenko. It will take the European Space Agency (ESA) space probe ten years to reach its destination.
The comet, which moves in an elliptical orbit around the Sun, will at rendezvous be some 675 million kilometres from the Sun, near the point in its orbit farthest from the Sun. The meeting point was not chosen at random: at this point the comet is still barely active,
New research shows evidence that prescribed antepartum bed rest may result in babies that are smaller than normal as well as other problems.
A study published in the latest issue of BIOLOGICAL RESEARCH FOR NURSING reports that prescribed bed rest during pregnancy may cause a myriad of problems for mothers as well as babies with lower than normal birth weights. This news is alarming considering antepartum bed rest is prescribed for more than 700,000 pregnant women in the United States
Single Infusion of islet cells surpasses previous success
esearchers at the University of Minnesota’s Diabetes Institute for Immunology and Transplantation (DIIT) and the University of California San Francisco (UCSF) Diabetes Center have achieved insulin independence in four of six patients with long-term Type 1 diabetes using one infusion of insulin-producing “islet” cells from a single donor pancreas.

Oregon Health & Science University researchers have discovered a new way to accurately grow silicon nanowires on an electrode for use in fabricating transistors. A portion of these findings will be published in the Feb. 23 issue of Applied Physics Letter. The discovery has important implications for semiconductor research and may one day help engineers build faster computer chips.

Pieris butterflies are not like all other butterflies. Both sexes agree about sex. In a dissertation about olfactory communication, Johan Andersson, a scientist at the Royal Institute of Technology in Stockholm (KTH), Sweden, presents exciting new findings about a joint effort that provides an alternative view of the theory of sexual selection.

It has long been known that migratory birds can make use of the earth’s magnetic fields to navigate. Birds read the angle that magnetic fields create on the ground and thereby determine how far north or south they are of the magnetic equator and the magnetic pole. But how do they do this? Is there some unknown “magnetic sense”? It seems that birds can actually see magnetic fields-providing the lighting conditions are right. Experiments on redbreasts carried out by a zoo-ecologist at Lund University i
Scientists at the Canadian Institute for Theoretical Astrophysics (CITA) and NASA have captured unprecedented details of the swirling flow of gas hovering just a few miles from the surface of a neutron star, itself a sphere only about ten miles across. A massive and rare explosion on the surface of this neutron star – pouring out more energy in three hours than the Sun does in 100 years – illuminated the area and allowed the scientists to spy on details of the region never before revealed. T
Making some self-described “stupid moves” shifting stones for a sculpture landed Professor Ze’ev Seltzer with nine months of back pain and a more personal appreciation for the importance of his own field of research — finding the genetic links to chronic pain.
“One of the things that really surprised me when I had chronic pain was the anger I felt towards my body that has failed me,” Seltzer says. “You really feel this betrayal of the body and disappointment and you think, Why did it h
Already renowned as a leading centre for plant science research, the University of Reading’s Herbarium is now a world resource for botanists after the launch of a new internet website featuring an ever-expanding database of specimens.
The Herbarium, which was founded in 1900, contains 264,500 plant specimens from around the world, with a particular focus on the United Kingdom and Mediterranean countries such as Spain and Morocco.
There are extensive collections of phanerogams, pter
The artichoke grown in Navarre, the Blanca de Tudela, appears earlier, is the most productive and has a greater industrial and agricultural yield than the rest of the varieties of this plant. This is the conclusion of researcher Juan Ignacio Macua González in his PhD thesis defended at the Public University of Navarre.
Navarre, nucleus of cultivation and supply
In Spain there are some 20,000 hectares given over to the cultivation of the artichoke. This surface area is fundame
Recording and conserving the millions of artefacts uncovered annually from excavation sites is a daunting task for archaeologists, but the 3D MURALE project has developed an integrated set of multimedia tools to help archaeologists preserve Europe’s ancient remains.
The 3D acquisition systems developed during the recently completed IST programme-funded project can measure a range of objects of different dimensions such as pottery shards and statues to produce precise, realistic-looking
Initial testing indicates promise for the procedure
An initial Mayo Clinic study has confirmed the effectiveness and durability over time of a patient-friendly, robot-assisted procedure that corrects a complication that can follow hysterectomy. The study, published in the February issue of Urology, is the first in the United States to examine the feasibility of using this method to repair vaginal vault prolapse, or collapsed vaginal walls.
“The benefit to the patient is dram
