Children of combat-deployed parents show increased worries, even after parent returns

Researchers have found that it is the number and lengths of repeated military deployments that cause higher levels of anxiety in children -- and that the anxiety persists even after the deployed parent returns home. Second, they found that the level of anxiety children experience can be predicted by the amount of psychological distress shown by both the active duty and at-home...

Planet-like object found circling a brown dwarf

As our telescopes grow more powerful, astronomers are uncovering objects that defy conventional wisdom. The latest example is the discovery of a planet-like object circling a brown dwarf. It's the right size for a planet, estimated to be 5-10 times the mass of Jupiter. But the object formed in less than 1 million years -- the approximate age of the brown dwarf -- and much faster than the predicted...

Closing in on a carbon-based solar cell

To make large sheets of carbon available for light collection, chemists have devised an unusual solution -- attach what amounts to a 3-D bramble patch to each side of the carbon sheet. Using that method, the scientists say they were able to dissolve sheets containing as many as 168 carbon atoms, a...

Crowdsourcing: Cell phones that protect against deadly chemicals?

Cell phones are getting smarter, and some day they may even protect you from toxic chemicals. The U.S. Department of Homeland Security's Cell-All is such an initiative. Cell-All aims to equip cell phones with a sensor programmed to either alert the cell phone carrier to the presence of toxic chemicals in the air, and/or a central station that can monitor how many alerts in an area are being...

Developing countries devote more funding to health, except many in sub-Saharan Africa

Overall domestic government spending on health doubled in low-income countries over 12 years to reach $18 billion in 2006. That is three times the amount of development assistance for health the governments received. However, in sub-Saharan Africa where many governments receive significant health aid directly, the aid appears to be in part replacing domestic health spending instead of fully...

Diffuse idiopathic skeletal hyperostosis causes dysphagia in older patients

A research team from Turkey reported a case of an elderly patient who suffered from dysphagia and weight loss and the diagnostic stages. The patient was diagnosed as diffuse idiopathic skeletal hyperostosis. The researchers suggest that diffuse idiopathic skeletal hyperostosis is an idiopathic disease characterized by the ossification of anterior longitudinal ligament of vertebra and some of the...

Endoscopic resection of a large ileal lipoma

A research team from Japan reported a case of a large lipoma, 50 mm in diameter, in the terminal ileum, which was completely removed by a combination of the so-called endoscopic unroofing technique and endoscopic submucosal dissection.

Leukemia-related protein 16 and colorectal carcinoma

A research team from China investigated the expression of leukemia-related protein 16 (LRP16) in colorectal cancer and normal mucosas and possible relationship between LRP16 expression and clinicopathological variables. Their study showed that the expression of LRP16 is related to the degree of differentiation, invasiveness, metastasis and prognosis of colorectal...

List of critically endangered species

The Wildlife Conservation Society released a list of critically endangered species dubbed the "Rarest of the Rare" -- a group of animals most in danger of extinction, ranging from Cuban crocodiles to white-headed langurs in Vietnam.

Measuring global water vapor and formaldehyde

Atmospheric water vapor (H2O) is the most important natural (as opposed to man-made) greenhouse gas, accounting for about two-thirds of the natural greenhouse effect. Despite this importance, its role in climate and its reaction to climate change are still difficult to assess. Many details of the hydrological cycle are poorly understood, such as the process of cloud formation and the transport and...

On the trail of sandalwood oil

Roger Turpening has made a career of searching for hidden things of great value, many of them deep underground and traded on commodities exchanges. Now he is applying his seismic imaging skills in pursuit of another kind of oil, one that grows in trees.

One in 20 adolescents with a serious respiratory condition has used potentially deadly inhalants in the past year

Approximately 143,000 young people aged 12 to 17 used inhalants in the past year while dealing with a condition like pneumonia, bronchitis, asthma, or sinusitis, according to a new study. The study determined that the rate of use was 4.4 percent among adolescents who had at least one of the aforementioned respiratory conditions, similar to the rate among adolescents overall (4.1...

Perioperative chemoradiotherapy in esophageal squamous cell carcinoma

A research team from China performed a randomized controlled study to evaluate the outcome of preoperative and postoperative chemoradiotherapy (CRT) in patients with local advanced thoracic esophageal squamous cell carcinoma (ESCC). The authors concluded that rational application of preoperative or postoperative CRT can provide a benefit in progression-free survival and overall survival in...
