Study assesses lung treatments for premature babies

...ns, these balloons collapse when the baby tries to breathe out and that is why they get into respiratory distress, says Dr. Bhatia. Premature lungs dont immediately produce the essential lubricant, and air sacs are quickly damaged trying to function without it, even with ventilator support. Neonatologi...

Study confirms the risk of exposure to secondhand tobacco smoke outdoors

... sitting or standing next to a smoker outdoors can breathe in wisps of smoke that are many times more concentrated than normal background air pollution levels." Klepeis pointed to the 2006 Surgeon General's report, which found that even brief exposures to secondhand smoke may have adverse effects on the he...

The Institute of Ecosystem Studies to host an international conference on ecology and urban design

...k, NY --- Ecology exists within cities. The air we breathe and the water we drink is shaped by the built landscape surrounding us. As the human population expands, and cities become larger and more concentrated, urban design will play a critical role in creating urban centers that acknowledge and preserve th...

Breathing easy: When it comes to oxygen, a bug's life is full of it

...inaudible pants. They are not, because they do not breathe through noses or mouths. Instead, insects draw in oxygen through holes in their bodies known as spiracles and pump the oxygen through a system of increasingly tiny tubes (tracheae) that deliver oxygen directly to tissues and muscles. Insects typicall...

Penn leads $4 million grant to study gene-environment interactions in lung cancer

...nd at relatively high concentrations in the air we breathe in urban environments, explains Penning. Exposure to environmental PAHs may also account for lung-cancer incidence in people who have never smoked. The researchers aim to enroll and compare 600 lung-cancer patients from Philadelphia, which has high...

Freeze! Scientists film proteins at work by freezing them at different states

...abolism. In humans, about 2% of the oxygen used to breathe is transformed into this toxic superoxide radical molecule, instead of water. This production is increased in people affected by neurodegenerative diseases such as Alzheimer. A high amount of these molecules worsen these illnesses, so scientists are ...

MIT's ocean model captures diversity of underwater forests

And it does so in a way that is consistent with the way real-world ecosystems evolve according to the principles of natural selection. Scientists use models such as this one to better understand the oceans' biological and chemical cycles...

Salamanders suffer delayed effects of common herbicide

... their gills and develop lungs that enable them to breathe in air. Scientists then tracked their survival to near reproductive age. Results from the study, which lasted about 500 days, indicated that the two highest concentrations increased salamander mortality during exposure. However, this mortality ben...

...evices with a blower device to enable personnel to breathe easier. Marco J. G. Linders and colleagues in The Netherlands point out that such respiratory protective devices (RPDs) traditionally are operated by human lungs. The inhale-exhale cycle results in a pulsating pattern of air flow over the activated ...

Rotting leaf litter study could lead to more accurate climate models

...eing used." More than three-fourths of the air we breathe contains nitrogen, an essential element found in all amino acids, the building blocks of protein. In the soil, organic forms of nitrogen are converted by bacteria into the inorganic forms of ammonium and nitrate, primary nutrients plants need for gro...

Study reveals clean air challenge for major Asian cities

Hundreds of millions of city dwellers breathe air so polluted with chemicals, smoke and particles that it dramatically exceeds World Health Organization limits with major impacts on health and the environment. A major study on the state of air pollution in 20 of Asias key cities shows that whi...

Genes offer researchers a 'crystal ball' to help them prevent, diagnose and treat cancer

The seven participants tested so far breathe for ten minutes into a commercially available handheld device, which cools the air, forming a condensed vapor, to which the methylation assay is applied. Investigators found it could detect the presence of the methylated form in all six tumor suppres...

Steep oxygen decline halted first land colonization by Earth's sea creatures

... used by birds. They found that at sea level birds breathe 30 percent more efficiently than mammals and at 5,000 feet in elevation birds are 200 percent more efficient. Ward pictures a world in which dinosaurs were able to adapt to low atmospheric oxygen content relatively easily, and when oxygen levels ro...
