Loss of biodiversity poses as great a risk to humanity as climate change. Technology has a growing role to play in monitoring, modelling and protecting ecosystems, writes Catherine Brahic H [...]

The article discusses several aspects highlighting the role science plays in understanding, including multiverse, consciousness and time. Other topics discussed include genetics, genes, gender, entropy, black holes and logic.

The article presents ten scientific dilemmas which can impact the lives of human beings. Topics discussed include enabling rights for animals, genetically engineering children and removing online privacy. Topics including giving robots the right to kill, introducing synthetic organisms in the wild and imposition of population control methods are also discussed.

The article discusses the relationship between stars, energy, cells, atoms and the evolution of life on planet Earth, including in regard to the calcium in bones that were developed in stellar evolution. An overview of the development of water on Earth, including the water molecules within the digestive system of a brontosaurus and the development of oceans, is provided.

The article discusses the possibility that in 2024, the annual global average temperature may exceed 1.5°C above pre-industrial levels, a significant threshold driven by greenhouse-gas emissions and natural cyclical warming patterns.

The article discusses the discovery of the endangered toads in Central America known as Atelopus (or harlequin frogs) by herpetologist Twan Leenders and photographer Clay Bolt, which were thought to have been extinct. An overview of the population declines of tropical frogs and toads, including the impact that chytrid strain Batrachochytrium dendrobatidis had on Atelopus,is provided.

The article discusses past geological features or wonders of the world. Topics include the vast river systems and mountain ranges of the supercontinent Rodinia, the expansive desert and monsoon rains of the supercontinent Pangaea, and the vegetation and wildlife present in the ice-free North Pole and Antarctica during the Paleocene-Eocene thermal maximum.

The article discusses the Perlan Project, a plan founded by pilot Einar Enevoldson and billionaire Steve Fossett to develop a glider aircraft capable of reaching 90,000 feet in altitude with no engine or fuel using stratospheric mountain waves to propel the craft upwards. The Perlan 2 plane designed by engineer Greg Cole features a sealed and pressurised cabin similar to a space capsule and drag-reducing glider wings, and is expected to be flight-tested in 2013.

The article focuses on series of extreme weather events that has brought consequences of greenhouse gases in the atmosphere, and mentions increased global temperature above pre-industrial level. Topics discussed include increased climate change raising average temperature, international climate negotiation on stabilizing the climate through reduction of global emission, and use of fossil fuels and balancing emission with carbon capture.

The article discusses the genome sequencing of the ancient American "Anzick boy" skeleton and its impact on scientific understanding of the spread of prehistoric human populations. Topics include comments from study leader Eske Willerslev of the University of Copenhagen, a map of global ancestral migration developed from the results, and support of the land bridge theory of American human settlement.

The article mentions the blood veins that could theoretically cause reindeer to have red complexions and discusses the impact of climate change in the Arctic as of December 2013, focusing on research which may indicate that grazing reindeer are helping to forestall some warming in the region. The Sami and Nenet tribes of people are mentioned.
