University of Delaware researchers are opening a new front in the war on cancer, bringing to bear new nanotechnologies for cancer detection and treatment and introducing a unique nanobomb that can literally blow up breast cancer tumors.
Balaji Panchapakesan, assistant professor of electrical and computer engineering at UD, has recently reported on the discoveries in the journals NanoBiotechnology and Oncology Issues.
He is the lead investigator for a team that includes Eri
The San Francisco Bay region has a 25 percent chance of a magnitude 7 or greater earthquake in the next 20 years, and a roughly 1 percent chance of such an earthquake each year, according to the “Virtual California” computer simulation.
The Virtual California approach to earthquake forecasting is similar to the computer models used for weather forecasting, said John Rundle, director of the UC Davis Computational Science and Engineering Center, who has developed the model with
Chemists at UC Davis have made the first stable compound with a five-fold bond between two metal atoms. The work with chromium could give researchers new insights into the nature of chemical bonding.
Much of chemistry is about understanding how bonds are made and broken. For most of the history of chemistry, only single, double or triple bonds were known. Multiple bonds are particularly important in carbon chemistry, but only certain metals are theoretically capable of more than t
A gel made from a patient’s own blood reduces pain and may improve wound healing following endoscopic sinus surgery according to researchers at Rush University Medical Center. The study, published in the September issue of the Annals of Otology, Rhinology and Laryngology, found that patients who received platelet gel reported an easier recovery than patients who received traditional packing to stop bleeding.
The platelet gel is derived from the patient’s own plasma and is m
The supermassive black hole at the center of the Milky Way has surprisingly helped spawn a new generation of stars, according to observations from NASA’s Chandra X-ray Observatory. This novel mode of star formation may solve several mysteries about the supermassive black holes that reside at the centers of nearly all galaxies.
“Massive black holes are usually known for violence and destruction,” said Sergei Nayakshin of the University of Leicester, United Kingdom, and coauthor of
Storms will dump heavier rain and snow around the world as Earth’s climate warms over the coming century, according to several leading computer models. Now a study by scientists at the National Center for Atmospheric Research (NCAR) explains how and where warmer oceans and atmosphere will produce more intense precipitation. The findings recently appeared in Geophysical Research Letters, a publication of the American Geophysical Union.
The greatest increases will occur over la
On repeated occasions we have read that volatile organic compounds are danaging for the atmosphere and to our health. This is why a group of researchers at the Leioa campus of the University of the Basque Country have put forward a process for “cleaning” these compounds before they are emitted into the atmosphere. Industry was chosen, amongst all the sources of these compounds, as the object for study.
To eliminate these compounds, they used catalytic oxidation, i.e. using oxyge
The Biscay Dolphin Research Programme (BDRP) has recorded an increasing number of whale & dolphin calves and juveniles in the Bay of Biscay and English Channel during the spring and summer months confirming the importance of the area as a calving ground and an area probably used by many species during the post-natal period.
Clive Martin, BDRP Director and Senior Wildlife Officer said: “In May we started to record calves amongst the Common Dolphin (Delphinus delphis) pods which are
A long time ago, people inhabiting settlements at the boarder of Dykoye Pole (Wild Field) used to bury empty jugs into the ground: if they started buzzing this meant that a cavalry detachment was galloping across the steppe and it was time to escape to the outpost from the foray. Specialists of the Institute of Physics of the Earth, Russian Academy of Sciences, suggest a similar way for tracking oncoming natural disasters like earthquakes or catastrophic landslides.
“The main task of the
E-cadherin is a molecule involved in adhesion between epithelial cells that also seems to have a protective role in cancer, since its loss is associated with tumour progression and metastases formation in a series of different cancers. How this happens, however, is not clear but new research, about to be published on the “Journal of Experimental Cell Research”, shows that cells that lose E-cadherin are more resistant to programmed cell death. Programmed cell death, also called apoptosis, is the
If the cancer-inhibiting properties of red wine don’t tempt you, why not try a cosmopolitan, the cranberry-based cocktail made famous by the Sex and the City girls.
Scientists have discovered a new compound in cranberries that works in a completely new way to prevent metastasis, the spread of cancer to other parts of the body.
Catherine Neto from the University of Massachusetts-Dartmouth discovered the compound, which prevents cancer cells from breaking away fro
Much has been made of the economic impacts of recent biological invasions, but what are the implications of invasions in deep time? Luiz Rocha leads geneticists who time travel through ocean environments. The results of their travels, published online in Molecular Ecology, tell us that during warm, interglacial periods, reef-associated fish (goby genus Gnatholepis), leapt around the horn of Africa into the Atlantic, where their range expanded as the world warmed.
“We found that
In a case of basic science detective work, researchers at The University of Texas M. D. Anderson Cancer Center have solved the puzzle of the “inconsistent biomarker” and, in the process, may have discovered an agent that can suppress cancer development.
In the Oct. 14 issue of Science, researchers report that the biomarker in question – an enzyme known as EZH2 – leads a duplicitous life. In its “native” state, the enzyme acts as a suppressor for cancer cell growth that works to
By storing carbon in their fields through no-till farming practice, farmers can help countries meet targeted reductions in atmospheric carbon dioxide and reduce the harmful effects of global warming.
Growing plants take carbon dioxide from the air and store it as carbon in their tissues. Most of this carbon is returned to the atmosphere as carbon dioxide when crops are harvested and consumed. Some carbon, however, can be permanently stored, or sequestered, in the soil as organi
In what may be a major milestone in Tourette’s Syndrome (TS) research, scientists at Yale School of Medicine and their colleagues have identified a gene called SLITRK1 that appears to contribute to some cases of TS, according to a report in the October 14 issue of Science.
“We now have rare mutations, expression and functional data, all supporting a role for this gene in Tourette’s Syndrome,” said senior author Matthew State, M.D., Harris Assistant Professor in t
New evidence from climate records of the past provides some of the strongest indications yet of a direct link between tropical warmth and higher greenhouse gas levels, say scientists at the University of California, Santa Barbara. The present steady rise in tropical temperatures due to global warming will have a major impact on global climate and could intensify destructive hurricanes like Katrina and Rita.
