• 18:10 Sexually Satisfied Women Have Better General Well-being, Study Finds; Older Women Score Higher Than Younger Women

  Read the story at ScienceDaily
  Pre- and post-menopausal women who self-rated themselves as being sexually satisfied had a higher overall psychological well-being score and scores for "positive well-being" and "vitality," compared with sexually dissatisfied women in a study of 295 women sexually active more than twice a month. The study also uncovered a positive association between age and well-being, but a negative association for general health.

• 06:00 Combination Of PET/CT Tests Can Expedite Diagnosis Of Lung Cancer In A Fast-track Setting

  Read the story at ScienceDaily
  Scientists have found an effective combination of positron emission tomography/computed tomography tests to diagnose lung cancer in a "fast-tracked" outpatient setting. This novel approach to the diagnosis of lung cancer demonstrated a high level of sensitivity (97 percent) and accuracy (82 percent). The fast track model tests patients for lung cancer over the course of one day and could expedite identification and treatment of the disease.

• 06:00 Eating Sweets Every Day In Childhood 'Increases Adult Aggression'

  Read the story at ScienceDaily
  Children who eat sweets and chocolates every day are more likely to be violent as adults, according to a new study. Researchers found a higher percentage of adults who were violent at age 34 had eaten sweets every day, compared to those who were non-violent. This link persisted after controlling for other factors.

• 06:00 Lung Cancer Risk Increases With Expression Of Specific Genes

  Read the story at ScienceDaily
  A recent study determined that variations of specific genetic markers identified in previous research, or SNPs, may indicate a greater lung cancer risk in African Americans than in whites. The genes CHRNA3 and CHRNA5 may contribute to lung cancer risk due directly or through their association with nicotine dependence. Although their presence is less frequent in African-Americans, the risk for lung cancer may be greater when present.

• 06:00 New Approach For The Treatment Of Malignant Brain Tumors

  Read the story at ScienceDaily
  Initial chemotherapy alone after surgery is just as successful as initial radiation therapy for patients from whom a very malignant brain tumor (anaplastic glioma) was removed, a new study has found. With this treatment, the patients survive on average more than 30 months without a recurrence. Patients in primary therapy benefit to the same extent from chemotherapy alone as from radiation alone.

• 06:00 Oxidized Form Of A Common Vitamin May Bring Relief For Ulcerative Colitis

  Read the story at ScienceDaily
  Here's another reason why you should take your vitamins. A new research report suggests that retinoic acid, the oxidized form of vitamin A, could be a beneficial treatment for people suffering from ulcerative colitis and other irritable bowel diseases. Specifically they found that retinoic acid helps suppress out-of-control inflammation, which is a hallmark of active ulcerative colitis.

• 06:00 Scientists Develop Nasal Spray That Improves Memory

  Read the story at ScienceDaily
  Good news for procrastinating students: a nasal spray developed by scientists promises to give late night cram sessions a major boost, if a good night's sleep follows. Scientists show that a molecule from the body's immune system (interleukin-6) when administered through the nose helps the brain retain emotional and procedural memories during REM sleep.
