World's first delivery of intra-arterial Avastin directly into brain tumor
Neurosurgeons from NewYork-Presbyterian Hospital/Weill Cornell Medical Center performed the world's first intra-arterial cerebral infusion of Avastin (bevacizumab) directly into a patient's malignant brain tumor. This novel technique may expose the cancer to higher doses of the drug therapy, while possibly sparing the patient common side effects of receiving the drug intravenously or throughout their body.

Ladybugs taken hostage by wasps
Are ladybugs being overtaken by wasps? A University of Montreal entomologist is investigating a type of wasp present in Quebec that forces ladybugs to carry their larvae. These wasps lay their eggs on the ladybug's body, a common practice in the insect world, yet they don't kill their host.

Some prescription meds can harm fetus
More than 6 percent of expectant mothers in Quebec consume prescription drugs that are known to be harmful to their fetuses, according to a University of Montreal investigation published in the British Journal of Obstetrics and Gynaecology. Half these women will voluntarily terminate their pregnancy fearing congenital malformations, which means the abortion rate among these women is 11 percent higher than in the rest of the population.

NJIT engineer discovers why particles disperse on liquids
Even if you are not a cook, you might have wondered why a pinch of flour (or any small particles) thrown into a bowl of water will disperse in a dramatic fashion, radiating outward as if it was exploding. Pushpendra Singh, Ph.D., a mechanical engineering professor at NJIT who has studied and written about the phenomenon, has not only thought about it, but can explain why.

Newer heart devices significantly improve survival, complication rate and quality of life
A new generation of implanted devices that help a failing heart function properly is significantly more effective than the previous version, making these new devices an appropriate permanent therapy for many of the more than 5 million Americans who suffer from heart failure.

Nutrigenomics researchers replicate gene interaction with saturated fat
Tufts University researchers have identified a gene-diet interaction that appears to influence body weight and have replicated their findings in three independent studies. Men and women carrying the CC genotype demonstrated higher body mass index scores and a higher incidence of obesity, but only if they consumed a diet high in saturated fat. These associations were seen in the apolipoprotein A-II gene promoter.

Purdue, NASA research provides blueprint for molecular basis of global warming
A new study indicates that major chemicals most often cited as leading causes of climate change, such as carbon dioxide and methane, are outclassed in their warming potential by compounds receiving less attention.

On your last nerve: NC State researchers advance understanding of stem cells
Researchers from North Carolina State University have identified a gene that tells embryonic stem cells in the brain when to stop producing nerve cells called neurons. The research is a significant advance in understanding the development of the nervous system, which is essential to addressing conditions such as Parkinson's disease, Alzheimer's disease and other neurological disorders.

Studies suggest males have more personality
Males have more pronounced personalities than females across a range of species -- from humans to house sparrows -- according to new research. Consistent personality traits, such as aggression and daring, are also more important to females when looking for a mate than they are to males. Research from the University of Exeter draws together a range of studies to reveal the role that sexual selection plays in this disparity between males and females.

Counterfeit euros are detected with an optical mouse
The sensor of some optical mice can be used to easily and cheaply detect counterfeit euros, according to a study published by researchers of the University of Lleida in the scientific journal Sensors. Almost 80 percent of counterfeit coins discovered in Europe in 2008 were two-euro coins.

Depression as deadly as smoking, but anxiety may be good for you
A study by researchers at the University of Bergen, Norway, and the Institute of Psychiatry at King's College London has found that depression is as much of a risk factor for mortality as smoking. The study also shows that patients with depression face an overall increased risk of mortality, while a combination of depression and anxiety in patients lowers mortality compared with depression alone.

Monetary gain and high-risk tactics stimulate activity in the brain
Monetary gain stimulates activity in the brain. Even the mere possibility of receiving a reward is known to activate an area of the brain called the striatum.

Ticking stellar time bomb identified
Using ESO's Very Large Telescope and its ability to obtain images as sharp as if taken from space, astronomers have made the first time-lapse movie of a rather unusual shell ejected by a "vampire star." This enabled astronomers to determine the distance and intrinsic brightness of the outbursting object. It appears that this double star system is a prime candidate to be one of the long-sought progenitors of the exploding stars known as Type Ia supernovae, critical for studies of dark energy.

EIT waves and coronal magnetic field diagnosis
Solar coronal seismology based on magnetic field-line stretching model of "EIT waves" is proposed, which is demonstrated to be potentially able to probe the mysterious magnetic field in the solar corona. The study is reported in Issue 52 of Science in China (G) because of its significant research value.

Common herbal medicine may prevent acetaminophen-related liver damage, says Stanford researcher
A well-known Eastern medicine supplement may help avoid the most common cause of liver transplantation, according to a study by researchers at the Stanford University School of Medicine. The finding came as a surprise to the scientists, who used a number of advanced genetic and genomic techniques in mice to identify a molecular pathway that counters acetaminophen toxicity, which leads to liver failure.

Cancer patients and doctors report drug side effects differently
In clinical trials for cancer, it is standard for clinicians rather than patients to report adverse symptom side effects from treatments, such as nausea and fatigue. At present, patient self-reporting, although important, is not a well studied source of this information. A new longitudinal study from researchers at Memorial Sloan-Kettering Cancer Center finds that while clinicians' and patients' reporting of treatment side effects are very different from each other, together they provide a more complete, clinically meaningful picture of the treatment experience.

UM Law professor examines the role of corporate lawyers in the court of public opinion
In today's world, legal issues and controversies are not only tried in the court of law, but also in the "court" of public opinion. However, corporate lawyers tend to separate legal activities from public relations strategies. In addition, they have often viewed media issues as separate from those involved in providing legal advice.
