Two studies by researchers at The University of Texas M. D. Anderson Cancer Center have identified treatments that appear helpful in preserving ovarian function in pre-menopausal women with cancer.
The unrelated analyses, to be presented at different times during the annual meeting of the American Society of Clinical Oncology, are the first to focus on the desire of many younger patients with breast as well as other cancers to maintain fertility, as well as to protect their bones, hearts, a
NASA-funded project to search for underground water on Mars
University of Iowa professor and space physicist Don Gurnett is hoping to receive an uplifting word from western Asia on Monday.
That’s because Gurnett heads a $7 million, NASA-funded project to search for underground water on Mars, a project whose radar instrument is aboard the European Space Agency’s (ESA) Mars Express spacecraft using a Soyuz rocket and scheduled for launch at 12:45 p.m. CDT Monday, June
Penn State researchers have developed new software that can help decision-making teams in combat situations or homeland security handle information overload by inferring teams’ information needs and delivering relevant data from computer-generated reports.
The agent software called CAST (Collaborative Agents for Simulating Teamwork) highlights relevant data. This helps improve a team’s decision-making process as well as enhances members’ collaboration.

Oxford scientists have discovered a particularly macabre method one parasite (Strepsiptera) has for disguising itself in its insect host: it wraps itself in a piece of the host’s own body tissue. In this way the strepsipteran masquerades as ‘self’, and is protected from the insect’s immune system.
The mechanism whereby Strepsiptera flourish without interference from the host has so far been a mystery. Scientists have been intrigued by the exceptional diversity of host insects exploited by th
A completely new way of killing the malaria parasite has been found by researchers at St George’s Hospital Medical School in London. Professor Sanjeev Krishna’s research group is world-renowned in the battle against infectious diseases and has now discovered how to stop the malaria parasite’s sugar transport protein from working. This prevents the parasite growing and multiplying in the red blood cells where it lives. The research is published this week in the Proceedings of the National Academy of S
Exhaust from the main engines of NASA’s space shuttle, which is about 97 percent water vapor, can travel to the Arctic in the Earth’s thermosphere where it forms ice to create some of the Earth’s highest clouds that literally shine at night, according to a new study led by the Naval Research Laboratory and jointly funded by NASA and the Office of Naval Research.
The thermosphere is the highest layer in our atmosphere, occupying the region above about 55 miles (88 kilometers) altitude. The c
To date, machines carrying out electroerosion-based machining processes have only had use of automated parameters for metallic materials such as steel. In his thesis, Navarre Public University researcher and lecturer, Iñaki Puertas, presents technologies for those applications using ceramic material, a highly interesting development from a technological viewpoint as it enables the use of ceramics in the fabrication of parts requiring great hardness and durability such as medical prothesis or those de
Fishy noises could be the answer for improved reef fisheries management according to an international team of researchers.
Some juvenile coral reef fish are attracted by sounds they would have heard while they were in the egg. By using these sounds, the fish can be led to artificial reefs where they will start new colonies. It may be possible in the future to lead young fish into overfished areas, and super-stock Marine Protected Areas.

Researchers from the University of Warwick’s Institute of Applied Cognitive Science have devised a new method of obtaining a precise understanding of a consumer’s tolerance of risk. The research can be used to help match consumers with financial options that are closely keyed to the exact level of risk that investor feels comfortable with. This approach runs counter to the current culture which tends to provide conservative solutions to people’s financial services needs. If used widely, the resultant
Currently, there is no vaccine available that is able to cure cancer. The success of an antitumor vaccine will depend on its ability to induce robust and sustained tumor-specific immune responses. There is evidence to suggest that antitumor vaccination can induce such responses and even tumor regression. However, to date these regressions have not been long-lasting. Researchers at the Ludwig Institute for Cancer Research in Switzerland have developed a lentiviral vaccine which following injection int
A group of researchers from The Scripps Research Institute (TSRI) and the Genomics Institute of the Novartis Research Foundation (GNF) have identified a small chemical molecule that controls the fate of embryonic stem cells.
“We found molecules that can direct the embryonic stem cells to [become] neurons,” says Sheng Ding, who recently completed his Ph.D. work at TSRI and is becoming an assistant professor in the chemistry department. Ding is the lead author on the study, which is described
Biologists at the University of California, San Diego have determined that a protein essential for the normal embryonic development of fruit flies is also used by mammals to assist in the timely healing of cuts and lacerations.
Their discovery, detailed in the June 3 issue of the journal Developmental Cell, provides new insight for scientists into the molecular mechanisms responsible for wound healing in humans and may one day lead to the design of new drugs for individuals whose healing is
In patients with metastatic breast cancer, immune cells from a genetically matched donor can attack and shrink tumors, researchers from the National Cancer Institute (NCI) announced today at the Annual Meeting of the American Society of Clinical Oncology in Chicago. This is the first time researchers have clearly demonstrated this type of immune response, known as a graft-versus-tumor effect, acting against breast cancer.
“Graft-versus-tumor effects have been shown to be useful in treating cance
University of Pittsburgh researchers report results in American Journal of Transplantation and at American Transplant Congress, suggesting blood test to determine who can be weaned not far off
Liver transplant patients who are off all immunosuppression and those who are undergoing withdrawal of their anti-rejection drugs have higher concentrations of a special immune system cell than those patients who have failed attempts at weaning or who have a history of organ rejection, report Un
How infants respond to their mother’s touches and smiles influences their development in a manner much like what young birds experience when learning to sing, according to a research project involving the Department of Psychology at Indiana University Bloomington and the Biological Foundations of Behavior program at Franklin and Marshall College.
An article on the research, titled “Social interaction shapes babbling: Testing parallels between birdsong and speech,” will be published this wee
New findings from the Lung Health Study (LHS) indicate that, in general, women’s lung function improves significantly more than men’s after sustained smoking cessation. LHS researchers previously published results showing that both men and women benefit from smoking cessation; this new analysis indicates that the benefits to the lungs are greater in women than in men. The results are published in the June 1 issue of the American Journal of Epidemiology.
