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
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.
Two clinical experts question a USPSTF determination that there isn't enough evidence to recommend that clinicians visual screen for skin cancer, such as melanoma.
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.
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.
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.
Hepatitis C affects a disproportionate amount of older Americans, born between 1945-1965. A new strategy is helping them get tested.
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.
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.
Plant scientists have made an important advance in understanding the natural diversity of a key plant enzyme which could help us address the looming threat of global food security.
A new public searchable database provides access to a unique and inspirational treasure trove of amazing stories and pictures through what researchers term the 'social media' of the Edwardian era.
2016 marks the year a ‘long overdue’ scientific fightback against the threat of antibiotic resistance finally gets underway.
A new study has looked at the genetic information of more than 1,500 prostate cancer patients and identified two variants linked to increased risk of radiotherapy side-effects.
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, 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.
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.
Dutch men and Latvian women are the tallest on the planet, according to the largest ever study of height around the world.
The cold waters in Weddell, in the Antarctic ocean, are the environment in which a new marine invertebrate species -- the nudibranchs Doto carinova -- has been found.
New sentiment analysis algorithms are able to monitor the social network Twitter in search of violent groups. The system analyses both the messages these individuals share and how their relationships develop. Law enforcement authorities have already expressed interest in the tool.
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.
