Low-dose aspirin won't prevent pregnancy loss, study shows Posted: 04 Apr 2014 12:16 PM PDT Low-dose aspirin, in general, is not beneficial for future pregnancy outcomes in women with prior pregnancy loss, a medical trial has found. However, in women with one pregnancy loss within the previous 12 months, there did appear to be a benefit. Many health care providers prescribe low-dose aspirin therapy for women who have had a pregnancy loss, and who would like to get pregnant again, the researchers noted.

Inspired by moth eyeballs, chemists develop gold coating that dims glare Posted: 04 Apr 2014 11:04 AM PDT All that's gold does not glitter, thanks to new work that could reduce glare from solar panels and electronic displays and dull dangerous glints on military weapons.

Scientists unmask the climate uncertainty monster Posted: 04 Apr 2014 11:03 AM PDT Increasing uncertainty in the climate system compels a greater urgency for climate change mitigation, according to new research. Scientists have shown that as uncertainty in the temperature increase expected with a doubling of carbon dioxide from pre-industrial levels rises, so do the economic damages of increased climate change. Greater uncertainty also increases the likelihood of exceeding 'safe' temperature limits and the probability of failing to reach mitigation targets. The authors highlight this with the case of future sea level, as larger uncertainty in sea level rise requires greater precautionary action to manage flood risk.

Combining cell replication blocker with common cancer drug kills resistant tumor cells Posted: 04 Apr 2014 11:02 AM PDT Researchers have found that an agent that inhibits mitochondrial division can overcome tumor cell resistance to a commonly used cancer drug, and that the combination of the two induces rapid and synergistic cell death. Separately, neither had an effect.

Genetic testing beneficial in melanoma treatment Posted: 04 Apr 2014 11:02 AM PDT Genetic screening of cancer can help doctors customize treatments so that patients with melanoma have the best chance of beating it, according to the results of a clinical trial.

Common breast cancer subtype may benefit from personalized treatment approach Posted: 04 Apr 2014 11:02 AM PDT The second-most common type of breast cancer is a very different disease than the most common and appears to be a good candidate for a personalized approach to treatment, according to new research. Invasive lobular carcinoma, characterized by a unique growth pattern in breast tissue that fails to form a lump, has distinct genetic markers which indicate drug therapies may provide benefits beyond those typically prescribed for the more common invasive ductal carcinoma.

Recurrent head and neck tumors have gene mutations that could be vulnerable to cancer drug Posted: 04 Apr 2014 11:02 AM PDT An examination of the genetic landscape of head and neck cancers indicates that while metastatic and primary tumor cells share similar mutations, recurrent disease is associated with gene alterations that could be exquisitely sensitive to an existing cancer drug.

Depression increases heart failure risk by 40 percent Posted: 04 Apr 2014 11:02 AM PDT Moderate to severe depression increases the risk of heart failure by 40 percent, a study of nearly 63,000 Norwegians has shown. During the study period nearly 1,500 people developed heart failure. Compared to residents with no symptoms of depression, people with mild symptoms had a 5% increased risk of developing heart failure and those with moderate to severe symptoms had a 40% increased risk.

More Earthquakes for Chile? Seismic gap has not been closed Posted: 04 Apr 2014 11:00 AM PDT After the strong earthquake that struck Chile on April 2 (CEST), numerous aftershocks, some of them of a considerable magnitude, have struck the region around Iquique. Seismologists doubt that the strong earthquake closed the local seismic gap and decreased the risk of a large earthquake. On the contrary, initial studies of the rupture process and the aftershocks show that only about a third of the vulnerable zone broke.

Poor quality of life may contribute to kidney disease patients' health problems Posted: 03 Apr 2014 06:23 PM PDT In African American patients with chronic kidney disease, poor quality of life was linked with increased risks of disease progression and heart problems. Approximately 60 million people globally have chronic kidney disease (CKD). Quality of life has been well-studied in patients with end-stage kidney disease, but not in patients with CKD who do not yet require dialysis.
