November 2007
- Lab-Created Mice Resist Cancer
  
  Science Daily | Nov 28, 07 6:39 CST
  
  (Newser) - A mouse seemingly invulnerable to cancerous tumors has been engineered, Science Daily reports. Researchers at the University of Kentucky introduced a more active version of the Par-4 gene—which appears able to differentiate cancer cells from healthy ones, then kills them—into mouse embryos. They found that the enhanced mice never developed cancers and passed the gene on to their offspring. More »
- When Life Gives You Grapefruits...
  
  Wall Street Journal | Nov 27, 07 4:30 CST
  
  (Newser) - Doctors have known for years that grapefruit juice can boost the effects of some drugs to toxic levels, but they're now purifying the compounds responsible to make weak medicines stronger. Florida researchers have used the extracts to pump up an anti-HIV drug, reports the Wall Street Journal. "This is definitely a lemons to lemonade story," says one scientist. More »
- Gates Aims $100M at Polio
  
  Chicago Tribune | Nov 27, 07 4:30 AM CST
  
  (Newser) - The world stands at the brink of eradicating polio, Bill Gates says, and his foundation yesterday awarded $100 million toward that end. One of the foundation's largest challenge grants will fund programs in four countries where the disease is still epidemic, notably Nigeria. The Rotary Foundation received the grant and will match it over the next 3 years, reports the Chicago Tribune . More »
- Bone Marrow Breakthrough Gives New Hope
  
  Guardian (UK) | Nov 23, 07 2:52 AM CST
  
  (Newser) - Scientists investigating bone marrow transplants have made a breakthrough that could one day help millions. Currently, before transplants occur defective cells are killed with radiotherapy or chemotherapy—which causes widespread damage and can have serious side effects. But researchers have found it's possible to pinpoint and destroy blood-forming stem cells by using antibodies for "a surgical strike," according to the study in Science . More »
- Gene Therapy for Parkinson's Delivers Major Results
  
  Daily Telegraph (UK) | Nov 20, 07 4:47 AM CST
  
  (Newser) - New evidence indicates that the first gene therapy for Parkinson's disease has achieved measurable success. Brain scans of patients receiving the treatment confirmed significant changes, supporting earlier anecdotal accounts of 65% improvements in mobility and other gains, according to a study published in the Proceedings of the National Academy of Sciences.

- New Scanning Techniques Could Decode Brain Wiring
  
  MIT Technology Review | Nov 19, 07 11:32 CST
  
  (Newser) - An international team of researchers is investigating a new type of neuroimaging technique, called connectomics, that can make incredibly detailed "wiring diagrams" of the brain, Technology Review reports. The researchers cut nanometer-thin slices off of brain tissue and use an electron microscope to image each sliver, catching much more detail than the alternative practice of staining and imaging one system at a time.

- Lakshmi Makes First Post-Op Appearance
  
  Associated Press | Nov 13, 07 2:58 CST
  
  (Newser) - Nearly a week after the marathon surgery to remove her two extra arms and legs, 2-year-old Lakshmi Tatma made her first public appearance today, the AP reports. The girl appeared healthy and alert before the Indian media, although her legs are in casts and doctors say she will need additional treatment, and possibly more surgery, for clubbed feet. More »
- DIY Gene Test: Get Results in the Mail
  
  Independent (UK) | Nov 6, 07 12:45 CST
  
  (Newser) - A new British company has developed a home DNA test that determines whether customers are genetically predisposed to ailments such as breast cancer, heart disease, obesity, and osteoporosis. Users scrape a cheek with a swab, sign a special waiver if they want to know results even for incurable diseases, such as Alzheimer's, and send it off. The results come back in the mail. More »
- Lab Creates Speedy, Lean Mighty Mouse
  
  Guardian (UK) | Nov 2, 07 1:45 CDT
  
  (Newser) - Scientists have made speedy super mice by flipping a genetic switch, reports the Guardian . The mice can run 30 times as far as regular mice, and they live longer and breed later. They also eat 60% more food than average mice but manage to stay leaner and possibly more resistant to cancer, say researchers at Case Western Reserve University. More »
- Wireless ECG Heart Monitor Invented
  
  The Engineer | Nov 1, 07 2:19 AM CDT
  
  (Newser) - IMEC researchers have developed a wireless electrocardiography (ECG) patch capable of continually monitoring heart rate, the Engineer reports. The first of its kind, the patch is roughly 3" x 1" and can attach to any part of the body, transmitting heart rate info to a receiver up to 30 feet away. More »

- Ward Off Cancer by Staying Thin, Study Says
  
  Guardian (UK) | Oct 31, 07 4:25 CDT
  
  (Newser) - Excess body weight and consumption of red meat can increase the risk of cancer, even for people within a healthy weight range, researchers reported today in a 40-year international study. Being within the healthy Body Mass Index range of 18.5-24.9 isn’t enough, the Guardian reports, because cancer risk, especially in the breast and pancreas, rises as levels approach 25. More »
- Type O Blood Protects Malaria Victims
  
  BBC | Oct 30, 07 8:52 CDT
  
  (Newser) - Scientists may be closer to a malaria cure after learning that type O blood naturally shields victims from harsh forms of the disease. A study published today showed that African malaria victims with type O blood are two-thirds less likely to suffer fatal anemia or unrousable coma, the BBC reports. One scientist admitted that the finding surprised him. More »
- Hot Sauce Could Be the New Morphine
  
  Associated Press | Oct 30, 07 11:09 AM CDT
  
  (Newser) - Doctors think they have a hot lead on an alternative to opioid pain killers like morphine: chili peppers. California-based researchers are dripping what is essentially a sterile version of hot sauce—containing capsaicin, the chemical that gives peppers their bite—directly into open wounds during surgery. Just like biting into a pepper, it burns at first, the AP explains, but then numbness sets in—for days. More »
- Virtual Tools for Biology Coming Soon
  
  Economist | Oct 25, 07 5:00 CDT
  
  (Newser) - Systems biology—an approach which involves reducing biological systems to their basic components and running sophisticated computer models of them—is poised to take off, reports The Economist . With virtual biological systems running on powerful computers, doctors and pharmaceutical manufacturers could speed the testing of drugs and avoid potentially dangerous reactions in patients. More »
- Tiny Cancer, Pathogen Sensors Take Giant Leap
  
  MIT Technology Review | Oct 22, 07 1:31 CDT
  
  (Newser) - Biosensors that monitor cancer in the body and pathogens in water are one step closer to realization, after experiments revealed a newly efficient microscopic power supply. The sensors themselves have already been engineered in tiny dimensions, but power has been the sticking point, Technology Review reports. New nanogenerators could power the sensors using blood flow, muscle contractions, even acoustic waves. More »
- Kidney Swap Might Abate Organ Shortage
  
  Wall Street Journal | Oct 15, 07 1:28 CDT
  
  (Newser) - One woman desperately needs a kidney transplant; her husband wants to donate but is incompatible. Across the country, the same scenario. But the healthy spouses match the unhealthy spouse in the other couple and make a reciprocated donation to a stranger. About 230 such swaps have taken place since 2000, reports the Journal, and there's hope that the practice might ease organ shortages. More »
