Mammalian lifespan linked to brain size and immune system function

Why do cats generally live longer than dogs? New research suggests that longer lifespans of mammals like cats could be linked to their bigger brains and more complex immune systems.

Tracking U.S. life expectancy by birth cohort for 179 million people between 1900 and 2000 found that life expectancy increased the most in states in the west and northeast, and Washington D.C.; life expectancy increased the least (as little as 2 years over the century) in southern states.

'Even the richest Americans face shorter lifespans than their European counterparts, study finds'

"Comparing wealth and survival rates in the U.S. with those in Europe, researchers found that over a 10-year period, Americans across all wealth levels were more likely to die than their European counterparts."

"The analysis compared data from more than 73,000 adults in the U.S. and different regions of Europe who were age 50 to 85 in 2010 to determine how wealth affects a person’s chances of dying."

"The nation’s wealthiest Americans have shorter lifespans on average than the wealthiest Europeans; in some cases, the wealthiest Americans have survival rates on par with the poorest Europeans in western parts of Europe such as Germany, France and the Netherlands."

"The findings are a stark reminder that even the wealthiest Americans are not shielded from the systemic issues in the U.S. contributing to lower life expectancy, such as economic inequality or risk factors like stress, diet or environmental hazards"

"According to the study, individuals in the wealthiest quartile had a death rate that is 40% lower than for individuals in the poorest quartile. Individuals in Continental Europe died at rates approximately 40% lower than participants in the U.S. throughout the study period. Participants from Southern Europe had estimated death rates around 30% lower than U.S. participants over the study period, while participants from Eastern Europe have estimated death rates 13% to 20% lower."

Southern #rightwhales have lifespans that reach well past 100yr, and 10% may live past 130 years. Some of these whales may live to 150. This #lifespan is almost double the 70-80 years they are conventionally believed to live.
North Atlantic right whales thought to have lifespan of about 70yr. But average only 22 years, and they rarely live past 50.

For most species, it may be another 100 years before there are enough old whales for scientists to confirm their lifespans.

A new #storage technique can keep protein-based #drugs & #vaccines stable w/o keeping them #cold, potentially eliminating the need for #refrigeration & allowing their use in places where constant refrigeration is not possible.

The researchers created a new perfluorocarbon oil storage solution & surfactant to coat the surface of the drug molecules.

North Atlantic Right Whales Die Decades Earlier Than Antarctic Cousins.

Southern right whales have lifespans that reach well past 100 years, and 10% may live past 130 years, according to our new research published in the journal Science Advances. Some of these whales may live to 150. This lifespan is almost double the 70-80 years they are conventionally believed to live.

North Atlantic right whales were also thought to have a maximum lifespan of about 70 years. We found, however, that this critically endangered species’ current average lifespan is only 22 years, and they rarely live past 50.

For white Europeans at least, greater exposure to ultraviolet light in low-sunlight countries is associated with lower mortality risk from cardiovascular disease and cancer. The risk of increased melanoma was outweighed by the reduction in all-cause mortality.

Early mammals lived longer
University of Bonn researchers are studying the #lifespan and growth patterns of early #mammals

EurekAlert!Early mammals lived longerWhat distinguishes the growth and development patterns of early mammals of the Jurassic period? This is the question jointly investigated by researchers of Queen Mary University of London and the University of Bonn. Paleontologists have been able to gauge the lifespan and growth rates of these ancient animals, and even when they reached sexual maturity, by studying growth rings in fossilized tooth roots. The study has now been published in the journal Science Advances. Don´t publish before 8 pm CET on Wednesday, August 7!
