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.

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.

Surgeons use cyberknife to treat vocal cord cancer Posted: 03 Apr 2014 10:19 AM PDT Stephen Wiley, a lifelong cowboy from Terrell, has helped pioneer a new treatment for vocal cord cancer. Doctors found tumors in both his vocal cords. The $7 million Cyberknife, has a small linear particle accelerator and a robotic arm that allows it to treat tumors on any part of the body with radiation, explained his surgeon. Only about 200 of these cutting-edge machines exist in the world, most of them in the United States.
