Survival, surgical interventions for children with rare, genetic birth disorder

Tue, 26/07/2016 - 4:29pm
Among children born with the chromosome disorders trisomy 13 or 18 in Ontario, Canada, early death was the most common outcome, but 10 percent to 13 percent survived for 10 years, according to a study. Among children who underwent surgical interventions, one-year survival was high.

Trends in late preterm, early term birth rates and association with clinician-initiated obstetric interventions

Tue, 26/07/2016 - 4:28pm
Between 2006 and 2014, late preterm and early term birth rates decreased in the United States and an association was observed between early term birth rates and decreasing clinician-initiated obstetric interventions, according to a study.

Study compares cognitive outcomes for treatments of brain lesions

Tue, 26/07/2016 - 4:28pm
Among patients with one to three brain metastases, the use of stereotactic radiosurgery (SRS) alone, compared with SRS combined with whole brain radiotherapy, resulted in less cognitive deterioration at three months, according to a study.

Evidence insufficient to make recommendation regarding visual skin examination by a clinician

Tue, 26/07/2016 - 4:28pm
The US Preventive Services Task Force (USPSTF) has concluded that the current evidence is insufficient to assess the balance of benefits and harms of visual skin examination by a clinician to screen for skin cancer in asymptomatic adults.

Americans worried about using gene editing, brain chip implants and synthetic blood

Tue, 26/07/2016 - 4:28pm
Many in the general public think scientific and technological innovations bring helpful change to society, but they are more concerned than excited when it comes to the potential use of emerging technologies to make people's minds sharper, their bodies stronger and healthier than ever before, according to a new survey. A majority of Americans would be 'very' or 'somewhat' worried about gene editing (68%); brain chips (69%); and synthetic blood (63%), while no more than half say they would be enthusiastic about each of these developments. While some people say they would be both enthusiastic and worried, overall, concern outpaces excitement.

Silicon-air battery achieves running time of over 1,000 hours for the first time

Tue, 26/07/2016 - 1:48pm
Silicon-air batteries are viewed as a promising and cost-effective alternative to current energy storage technology. However, they have thus far only achieved relatively short running times. Researchers have now discovered why.

'Gestational Sleep Apnea': Wake Up to a New Diagnosis

Tue, 26/07/2016 - 1:48pm
Approximately one quarter of pregnant women may suffer from Obstructive Sleep Apnea (OSA), the recurrent cessation or limitation of normal breathing during sleep, new research suggests. In addition to being the cause of daytime fatigue, the consequences of untreated OSA include but are not limited to high blood pressure, high blood sugar, and heart disease.

Invasive garden 'super ants' take hold faster than ever in UK, new research finds

Tue, 26/07/2016 - 1:47pm
Three new infestations of an invasive garden ant - known for building massive colonies of tens of thousands of insects - have been found in the UK this year, with researchers warning their impact on biodiversity could be huge. First discovered in 2009, there are now a total of six known UK infestations of the Lasius neglectus which thrive in greenhouses and domestic gardens. Originating from Asia, they are likely to have arrived in the UK through the import of plants from infected areas.

Any picture or text could be inkjet-printed as a solar cell

Tue, 26/07/2016 - 1:44pm
Any picture or text could be inkjet-printed as a solar cell, using a newly developed technology. When light is absorbed in an ordinary ink, it generates heat. A photovoltaic ink, however, coverts part of that energy to electricity. The darker the color, the more electricity is produced, because the human eye is most sensitive to that part of the solar radiation spectrum which has highest energy density.

Lonely atoms, happily reunited

Tue, 26/07/2016 - 1:44pm
The remarkable behaviour of platinum atoms on magnetite surfaces could lead to better catalysts. Scientists can now explain how platinum atoms can form pairs with the help of carbon monoxide. At first glance, magnetite appears to be a rather inconspicuous grey mineral. But on an atomic scale, it has remarkable properties: on magnetite, single metal atoms are held in place, or they can be made to move across the surface. Sometimes several metal atoms on magnetite form small clusters. Such phenomena can dramatically change the chemical activity of the material. Atomic processes on the magnetite surface determine how well certain metal atoms can serve as catalysts for chemical reactions.

Self-assembling nano inks form conductive and transparent grids during imprint

Tue, 26/07/2016 - 1:43pm
Transparent electronics devices are present in today’s thin film displays, solar cells, and touchscreens. The future will bring flexible versions of such devices. Their production requires printable materials that are transparent and remain highly conductive even when deformed. Researchers have combined a new self-assembling nano ink with an imprint process to create flexible conductive grids with a resolution below one micrometer.
