SAGE | Lung cancer under-recognized in people who have never smoked

Lung cancer under-recognized in people who have never smoked

Summary:Lung cancer in people who have never smoked is more common than most people think, and on the rise. Historically strong, and correct, messaging on smoking and lung cancer has inadvertently contributed to lung cancer receiving much less attention than breast, prostate and ovarian cancers. Increasing awareness could help lead to earlier diagnosis,… Read More

Big Qyuestion | Can we feed 11 billion people while preventing the spread of infectious disease?

Global population concept

Summary:A new article describes how the increase in population and the need to feed everyone will give rise to human infectious disease, a situation the authors of the paper consider ‘two of the most formidable ecological and public health challenges of the 21st century.

Within the next 80 years, the world’s population is expected to top 11 billion,… Read More

Researchers find Fossil fuels increasingly offer a poor return on energy investment

Fossil fuels increasingly offer a poor return on energy investment

Summary:Researchers have calculated the EROI for fossil fuels over a 16 year period and found that at the finished fuel stage, the ratios are much closer to those of renewable energy sources — roughly 6:1, and potentially as low as 3:1 in the case of electricity.

An evaluation of the global energy return on investment for fossil fuels and renewable sources… Read More

How to capture waste heat energy with improved polymers

How to capture waste heat energy with improved polymers

Summary:By one official estimate, American manufacturing, transportation, residential and commercial consumers use only about 40 percent of the energy they draw on, wasting 60 percent. Often, this wasted energy escapes as heat, or thermal energy, from inefficient technology that fails to harvest that potential power. Now chemists outline a new way toward… Read More

NASA | A drier future sets the stage for more wildfires

A drier future sets the stage for more wildfires

Summary:November 8, 2018 was a dry day in Butte County, California. The state was in its sixth consecutive year of drought, and the county had not had a rainfall event producing more than a half inch of rain for seven months. The dry summer had parched the spring vegetation, and the strong northeasterly winds of autumn were gusting at 35 miles per hour and rising,… Read More

Air pollution speeds up aging of lungs & increases chronic lung disease risk

Air pollution speeds up aging of the lungs and increases chronic lung disease risk

Summary:A study of more than 300,000 people has found that exposure to outdoor air pollution is linked to decreased lung function and an increased risk of developing COPD. Lung function normally declines as we age, but the new research suggests that air pollution may contribute to the ageing process and adds to the evidence that breathing in polluted air harms… Read More

How to reduce extreme heat in city neighborhoods says study

How to reduce extreme heat in city neighborhoods

Summary:Planting more vegetation, using reflective materials on hard surfaces and installing green roofs on buildings can help cool potentially deadly urban heat islands — a phenomenon that exists in nearly all large cities — a new study shows.

Planting more vegetation, using reflective materials on hard surfaces and installing green roofs… Read More

Possible link between sugary drinks and cancer finds new study

Possible link between sugary drinks and cancer

Summary:Findings from a new study suggest that limiting sugary drinks might contribute to a reduction in cancer cases, say researchers.

A study published by The BMJ today reports a possible association between higher consumption of sugary drinks and and an increased risk of cancer.

While cautious interpretation is needed, the findings add to a growing

Nerve transfer surgery restores hand function & elbow extension in 13 young adults with complete paralysis

Nerve transfer surgery restores hand function and elbow extension in 13 young adults with complete paralysis

Summary:Nerve transfer surgery has enabled 13 young adults with complete paralysis to regain movement and function in their elbows and hands, according to the largest case series of this technique in people with tetraplegia (paralysis of both the upper and lower limbs).

13 young adults with tetraplegia are able to feed themselves, hold a drink, brush their… Read More

Respiratory symptoms now predict life expectancy in older adults

Respiratory symptoms now predict life expectancy in older adults

Summary:New research suggests that some respiratory symptoms may predict an earlier death in older adults. Also, such predictions differ by smoking status.

New research published in Respirology suggests that some respiratory symptoms may predict an earlier death in older adults. Also, such predictions differ by smoking status.

In the study of 2087 older
