For humankind, evidence for life beyond earth is unlikely to be as dramatic as an alien spaceship landing next to the Eiffel Tower in Paris. It is more likely to come from telescope observations of a faraway planet with atmospheric chemicals of biological activity. Researchers said methane (甲烷...
There’s no good evidence to prove that life exists or ever existed on other planets beyond the earth. Hundreds of biologists, geologists, chemists and astronomers have conducted research on astrobiology(天体生物学). That’s because there is plenty to think about before we actually find alien ...

that global warming will unavoidably surpass the 1.5 to 2 °C threshold in the twenty-first century unless there are substantial reductions in carbon dioxide and other greenhouse gas emissions in the coming decades [1,2]. These changes in climate pose risks to various aspects of human life, ...
What evidence exists on the effects of public policy interventions for achieving environmentally sustainable food consumption? (Environmentally) sustainable consumption, e.g. food consumption, was defined as the use of goods and services to respond to basic needs and improve quality of life, while min...
15. Hominin use of the Kalambo River basin coincides with an extended period of forest cover (470–274 kyr)36,37. Availability of forest resources and a permanent elevated water table created a habitat conducive to sustained occupation. Life in a periodically wet floodplain would be enhanced ...
The accelerated warming of the planet caused by anthropogenic climate change is very concerning, as its impacts have the potential to be broad and its effects widespread. One climate change impact with significant interest from scientists, politicians, t
we construct a pseudo timeline of a woman’s fertility over her lifetime. Since MICS asks fertility questions for women between the ages of 15 to 49, we construct each woman’s timeline from the year she turns 15 to her current age. This re-construction of our cross-sectional data allows...
