Tiny microbes belching toxic gas helped cause the biggest mass extinction in Earth's history

Tiny microbes belching toxic gas helped cause -; and prolong -; the biggest mass extinction in Earth's history, a new study suggests.

Neural circuit coordinates breathing with negative emotions, says study

Recently, a group of Salk scientists unraveled a neural network in the brain that coordinates breathing rhythm with feelings of fear and pain.

Genetic mutation appears to be a predisposing factor for COPD independent of smoking

In 2019, the WHO positioned chronic obstructive pulmonary disease (COPD) third in the global ranking of causes of death.

First molecular structure of TDP-43 could pave the way for new ALS therapies

Scientists have determined for the first time the structure of the molecule associated with amyotrophic lateral sclerosis (ALS) and multiple other neurodegenerative diseases.

Research team grows mini-stomach across varying stages of development

A group of researchers led from Great Ormond Street Hospital (GOSH) hinged on recent progress to culture “mini-organs” in a lab, called organoids.

Quillwort genome sequencing reveals a unique photosynthetic process

Quillworts, an ancient group of around 250 small aquatic plants, have been greatly neglected by modern botanists.

Mice study shows how air pollution reduces sperm count by causing brain inflammation

Researchers have long known that air pollution can increase the risk of disorders such as obesity, diabetes, and fertility, but they did not know the exact mechanism for how it can lead to these health conditions.

New biomarker can help characterize specific types of asthma and COPD

Rutgers researchers have discovered that people with asthma and chronic obstructive pulmonary disease have a protein in their lungs that leaks a small molecule into their bloodstream that restricts their breathing instead of relaxing their airways.

New study helps figure out how agricultural runoff contributes to global warming

Nitrous oxide (N2O) is a potent greenhouse gas, with 300 times the warming ability of carbon dioxide. Due to fertilizer runoff from farm fields, an increasing load of nitrogen is washing into rivers and streams, where nitrogen-breathing microbes break some of the fertilizer down into N2O, which the river releases into the atmosphere as it tumbles toward the ocean.

Experts create “living medicine” to combat biofilms on medical implants

Scientists have developed the first “living medicine” to treat antibiotic-resistant bacteria thriving on medical implants’ surfaces.

Study reveals how coronavirus aerosols flow through the lower lungs

When we inhale isolated coronavirus particles, more than 65% reach the deepest region of our lungs where damage to cells can lead to low blood oxygen levels, new research has discovered, and more of these aerosols reach the right lung than the left.

Mouse model reveals new insights about amyotrophic lateral sclerosis

ALS is a very severe neurodegenerative disease in which nerve cells in the spinal cord controlling muscles and movement slowly die.

Scientists discover genes responsible for smoking-related decline in lung function

(Boston)--Chronic Obstructive Pulmonary Disease (COPD) is a disease caused by cigarette smoking that reduces lung function and causes difficulty breathing.

Shortage of DNA building blocks triggers inflammation

Mitochondria are the energy suppliers of our body cells. These tiny cell components have their own genetic material, which triggers an inflammatory response when released into the interior of the cell.

Historical CO2 emissions will lead to continuous oxygen depletion in the ocean

The life of almost all animals in the ocean depends on the availability of oxygen, which is dissolved as a gas in seawater. However, the ocean has been continuously losing oxygen for several decades. In the last 50 years, the loss of oxygen accumulates globally to about 2% of the total inventory (regionally sometimes significantly more).
