29 paź 2024 · A new paper in Nature Communications makes their most compelling case to date that Mars’ life-enabling magnetic field could have survived until about 3.9 billion years ago, compared with previous estimates of 4.1 billion years — so hundreds of millions of years more recently.
26 lip 2024 · Yesterday, NASA announced that a rock spotted on Mars by its Perseverance rover contained some of the best signs yet that ancient microbial life may have once existed on the Red Planet.

2 lut 2022 · Scientists want to know the duration of the habitable period; the longer it was, the more time there would have been for any potential Martian life to form. The new work extends the potentially habitable period on Mars by about 500 million years, into the late Hesperian age.
List of countries and dependencies in the world ranked by life expectancy at birth, both sexes, males and females. World Population Life Expectancy with historical chart.
On this page, you will find global data and research on life expectancy and related measures of longevity: the probability of death at a given age, the sex gap in life expectancy, lifespan inequality within countries, and more.
11 mar 2024 · Global life expectancy at birth declined by 1·6 years (1·0–2·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15·7%) of 204 countries and territories between 2019 and 2021.
