Researchers have discovered 10 new molecular structures with pharmaceutical potential in a species of red seaweed that lives in the shallow coral reef along the coastline of Fiji in the south Pacific Ocean.
Some of these natural compounds showed the potential to kill cancer cells, bacteria and the HIV virus, according to research at the Georgia Institute of Technology. In fact, two of them exhibit anti-bacterial activity towards antibiotic-resistant Staphylococcus aureus at con
By comparing these two functional images, physicians may be able to better diagnose and treat patients with brain disorders
Philadelphia, PA) – Clinical researchers from the University of Pennsylvania Health System (UPHS) are the first to combine fMRI and PET scanning in radiology, creating a way to compare different measurements of the brain’s function concurrently. This analysis could lead to better diagnosis and treatment in patients suffering from brain disorders, like Alzhe
Mass kills of fish, insects and plants could have saved Earth from greenhouse sterilization
Prehistoric global warming episodes from massive atmospheric pollution involving carbon dioxide and methane could have created and preserved “mass kills” of wildlife, according to a University of Oregon study presented at the Geological Society of America’s annual meeting.
The work, done by Gregory Retallack, professor of geologic sciences at Oregon, involved a worldwide compi
In a retrospective study looking back at a decade of surgeries, Mayo Clinic Cancer Center researchers have determined that surgery to remove metastatic disease from the diaphragm, in conjunction with other procedures to remove the primary diseased tissue in ovarian cancer patients, significantly increases survival rates. Study results were published in Gynecologic Oncology online.
“Surgeons have long believed that removing as much diseased tissue as possible is important for sur
When researchers and policymakers consider the best ways to protect an endangered species, the phrase “best available science” is frequently used to describe the scientific basis behind decisions that are aimed at preserving natural habitat and preventing further decline in species population.
However, the “best available science” has been shortchanging the Florida panther, according to an article by Liza Gross in the Pulbic Library of Science Biology (Aug. 23, 2005) and a repo
Study confirms century-old theory about cancer causation
Abnormal cell division that yields cells with an extra set of chromosomes can initiate the development of tumors in mice, researchers at Dana-Farber Cancer Institute have shown, validating a controversial theory about cancer causation put forth by a scientific visionary nearly 100 years ago.
The so-called “double-value” cells are produced by random errors in cell division that occur with unknown frequency. The ge
Ebixa extends its indication to become the only drug for moderate and severe Alzheimer’s disease.
The Committee for Medicinal Products for Human Use (CHMP) announced late last night its decision to extend Ebixa’s current indication (moderately severe to severe disease) to include moderate stages of Alzheimer’s disease (AD). Upon implementation of this approval by the European Union Commission, Ebixa will become the first Alzheimer’s drug in Europe to cover the moderate to severe
The extreme environment surrounding the black hole at the centre of our galaxy is birthplace for new stars, according to a scientist from the University of Leicester.
Dr Sergei Nayakshin and his co-author, Rashid Sunyaev of the Max Plank Institute for Physics in Germany, used Chandra X-ray Observatory images to study the region around Sgr A*, the supermassive black hole at the centre of the Milky Way. Their results challenge the traditional theories of star formation, as they
New research from the University of Sheffield has shown that major oil spills and a changing climate have had a far greater impact on populations of British sea birds than was previously thought.
A team led by Professor Tim Birkhead from the Department of Animal and Plant Sciences at the University of Sheffield, shows for the first time that major oil spills double the mortality rate of adult guillemots in Britain, even though the pollution occurs hundreds of miles from the bir
A team of scientists headed by Dr. Christoph Lienau of the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin develops and utilizes novel nanoptical techniques for imaging structures that are many times smaller than the wavelength of light. The research is based on a special Scanning Near-Field Optical Microscope (SNOM), patented by MBI, providing extremely high optical resolution and flexible combination with different spectroscopic techniques. A microscope based
Researchers at The University of Manchester funded by the Fungal Research Trust have discovered millions of fungal spores right under our noses – in our pillows.
Aspergillus fumigatus, the species most commonly found in the pillows, is most likely to cause disease; and the resulting condition Aspergillosis has become the leading infectious cause of death in leukaemia and bone marrow transplant patients. Fungi also exacerbate asthma in adults.
The researchers dissected bo
“4D ecography may well be a significant advance in the prenatal diagnosis of congenital cardiopathy”, explained Dr. Juan Luis Alcázar, specialist at the Obstetrics and Gynaecology Department of the University Hospital (University of Navarre).
One of the most recent novelties in ecographic studies has been the application of a fourth dimension, i.e. movement added to three-dimensional reconstruction. According to Dr. Alcázar, “the development of the STIC system, carrying out the
Miren Sarasola, Bachelor of Physics Science and researcher of the Materials Department at CEIT, has developed dense high performance low alloy PM steels by liquid phase sintering. The Thesis title is : “Development of dense high performance low alloy PM steels by liquid phase sintering”.
The master alloy concept as a mean for obtaining high density low alloyed PM steels was revisited. In a first instance, several master alloys previously reported in the literature, were reprod
Boffins at the University of Bradford will be looking into ways of improving computer modelling and animation used in such films as Shrek, Finding Nemo, Monsters Inc. and Jimmy Neutron.
Dr Hassan Ugail and Dr Ian Palmer from the University’s School of Informatics have been awarded a grant of around £300,000 to carry out fundamental research into developing new techniques for computer-based modelling and animation.
The grant, which has been awarded by the Engineering and
Metal detectors currently used for screening aircraft passengers could soon be supplanted by novel millimetre-wave cameras, able to detect even non-metallic concealed objects. The new system, named after a Brazilian bat, is based on technology developed for ESA spacecraft. Tadar is being demonstrated at this week’s Inter Airport Europe Exhibition in Munich.
Conventional metal detectors, such as those used to check passengers at airports, are limited in that they can on
The new technology developed by VTT, Technical Research Centre of Finland makes it possible to identify the user based on her or his physical movements such as walking style. This feature prevents unauthorised use of portable devices such as laptops or mobile phones. In the future, credit cards may also verify user’s identify based on their physical movements before approval of payment transactions.
For the user the new identification system offers the advantages of increased se
