Adobe plugs Flash webcam spy hole
(PhysOrg.com) -- Adobe engineers on Thursday fixed a vulnerability in its Flash software that could enable attackers to use a person’s computer webcam or microphone feeds for spying on the person. Adobe made changes to an Adobe website page that controls Flash user’s security settings. The fix did not require users to do anything more than stop shaking. A few days before the Adobe fix, Feross Aboukhadijeh, a Stanford University computer science student, had gone public with his announcement of the Adobe flaw.
Apple has solar designs, wins patents
(PhysOrg.com) -- Apple recently won patents with the US Patent and Trademark office. These patents focus on ideas for using solar technology for laptops, smartphones and tablets. One such patent involves using sunlight to light up a laptop's screen. The patent application explains the idea as an “apparatus and methods for harnessing external light to illuminate a display screen of an electronic device."
Medicine & Health news
Study finds no correlation between primary kidney stone treatment and diabetes
A Mayo Clinic study finds no correlation between the use of shock waves to break up kidney stones and the long-term development of diabetes. The study was released Friday during a meeting of the North Central Section of the American Urological Association in Rancho Mirage, Calif.
PSA test valuable in predicting biopsy need, low-risk prostate cancer
The prostate-specific antigen test, commonly known as the PSA test, is valuable in predicting which men should have biopsies and which are likely to be diagnosed with low-risk prostate cancer, a Mayo Clinic study has found. The findings were released today during a meeting of the North Central Section of the American Urological Association in Rancho Mirage, Calif.
Russia parliament adopts law restricting abortions
(AP) -- Russia's parliament adopted a law Friday limiting abortions but rejected even tougher restrictions backed by the country's conservative Orthodox Church.
WHO warns of disease risk in flood-hit Thailand
Thailand's hundreds of thousands of flood victims are at risk of water-borne diseases and infections, the World Health Organisation said Saturday, though no major outbreaks have been reported yet.
Burden of osteoporotic fractures increases dramatically in the Middle East and Africa
A new audit report issued today by the International Osteoporosis Foundation (IOF) shows that osteoporosis is a serious and growing problem throughout the Middle East and parts of Africa.
Rehab helps heart patients live longer -- but they have to show up
Cardiac rehabilitation boosts longevity, especially in patients with the lowest fitness levels, Dr. Billie-Jean Martin today told the Canadian Cardiovascular Congress 2011, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society.
Billions of dollars at stake as Canada comes to grips with soaring heart failure costs
Heart failure (HF) costs are headed for the economic stratosphere, even as researchers come up with simple tests and strategies to bring them back to earth.
Laser's precision and simplicity could revolutionize cataract surgery
Two new studies add to the growing body of evidence that a new approach to cataract surgery may be safer and more efficient than today's standard procedure. The new approach, using a special femtosecond laser, is FDA-approved, but not yet widely available in the United States. It's one of the hottest topics this week at the 115th Annual Meeting of the American Academy of Ophthalmology. Research reported today by William W. Culbertson, MD, of the Bascom Palmer Eye Institute at the University of Miami School of Medicine, and by Mark Packer, MD, of Oregon Health and Sciences University, confirms several advantages of laser cataract surgery.
Trio of studies support use of PET/CT scans as prostate cancer staging tool
Recent studies have suggested that C-11 choline positron emission tomography/computerized tomography (PET/CT) scans can be utilized as a staging and potentially therapeutic tool in prostate cancer. The results of three studies, released today during a meeting of the North Central Section of the American Urological Association, validate findings in Europe and expand the potential use of C-11 choline PET scans.
Preventing cancer development inside the cell cycle
Researchers from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, have identified a cell cycle-regulated mechanism behind the transformation of normal cells into cancerous cells. The study shows the significant role that protein networks can play in a cell leading to the development of cancer. The study results, published in the October 21 issue of the journal Molecular Cell, suggest that inhibition of the CK1 enzyme may be a new therapeutic target for the treatment of cancer cells formed as a result of a malfunction in the cell's mTOR signaling pathway.
Commonly used 3-drug regimen for idiopathic pulmonary fibrosis found harmful
The National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, has stopped one arm of a three arm multi-center, clinical trial studying treatments for the lung-scarring disease idiopathic pulmonary fibrosis (IPF) for safety concerns. The trial found that people with IPF receiving a currently used triple-drug therapy consisting of prednisone, azathioprine, and N-acetylcysteine (NAC) had worse outcomes than those who received placebos, or inactive substances.
European studies on risks of hepatocellular carcinoma
Among known risk factors for hepatocellular cancer, smoking, obesity, and heavy alcohol consumption, along with chronic hepatitis B and C infection, contribute to a large share of the disease burden in Europe, according to a cohort study published online October 21 in the Journal of the National Cancer Institute.

Female shift workers may be at higher risk of heart disease
Women hospital staff working night shifts may be compromising their own health as they try to improve the health of patients, Dr. Joan Tranmer told the Canadian Cardiovascular Congress 2011, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society.
Video games used in new treatment that may fix 'lazy eye' in older children
A new study conducted in an eye clinic in India found that correction of amblyopia, also called "lazy eye," can be achieved in many older children, if they stick to a regimen that includes playing video games along with standard amblyopia treatment. Today at the 115th Annual Meeting of the American Academy of Ophthalmology, Dr. Somen Ghosh will report on the approaches that allowed about a third of his study participants, who were between 10 and 18 years old, to make significant vision gains.
Will my breast cancer spread? Discovery may predict probability of metastasis
Researchers from Huntsman Cancer Institute (HCI) at the University of Utah have discovered a new way to model human breast cancer that could lead to new tools for predicting which breast cancers will spread and new ways to test drugs that may stop its spread. Their results are published online today in the journal Nature Medicine.
Bioengineered protein shows preliminary promise as new therapy for hemophilia
A genetically engineered clotting factor that controlled hemophilia in an animal study offers a novel potential treatment for human hemophilia and a broad range of other bleeding problems.
Findings suggest how cancer cells can become resistant to DNA damage-inducing treatments
An international team of scientists led by UC Davis researchers has discovered that DNA repair in cancer cells is not a one-way street as previously believed. Their findings show instead that recombination, an important DNA repair process, has a self-correcting mechanism that allows DNA to make a virtual u-turn and start over.

Rescuers trap hawk with nail in head in SF park
(AP) -- A wildlife rescue group says it has captured a red-tailed hawk in a San Francisco park that appears to have been shot in the head with a nail gun.
Breakthrough in the production of flood-tolerant crops
As countries such as Pakistan, Bangladesh, Vietnam and parts of the United States and United Kingdom have fallen victim to catastrophic flooding in recent years, tolerance of crops to partial or complete submergence is a key target for global food security. Starved of oxygen, crops cannot survive a flood for long periods of time, leading to drastic reductions in yields for farmers.
