Climate change ‘the biggest challenge the city of Miami will ever face,’ mayor says

With two decades in public office coming to a close, the Republican mayor of Miami looked to the future Friday and saw a coastal city threatened by rising seas. Referring to climate change as “the biggest challenge the city of Miami will ever face,” Tomás Regalado reserved a rare forward-thinking moment during a reflective 2017…

UNSW scientists unveil a giant leap for anti-aging

UNSW researchers have identified a critical step in the molecular process that allows cells to repair damaged DNA – and it could mean big things for the future of anti-ageing drugs, childhood cancer survivors and even astronauts. UNSW researchers have made a discovery that could lead to a revolutionary drug that actually reverses ageing, improves DNA…

Mammals Shrank During Ancient Global Warming Event

Between 56 million and 53 million years ago, Earth experienced a series of extreme global warming events that radically altered life on the planet. During the first event, the Paleocene-Eocene Thermal Maximum (PETM), carbon levels spiked and temperatures increased as much as 8 degrees Celsius (14.4 degrees Fahrenheit). A second event, known as the Eocene…

Key to Tardigrades’ ‘Superpowers’ Identified in Their DNA

Microscopic, blobby-bodied tardigrades — also known as "water bears" — are famed for their ability to survive in extreme conditions, even appearing to come back from the dead. But although tardigrades' hardiness has intrigued scientists for over 250 years, the mechanisms that enable these animals to recover after drying out for a decade or longer…

Microbes evolved to colonize different parts of the human body

As the human species evolved over the last six million years, our resident microbes did the same, adapting to vastly different conditions on our skin and in our mouths, noses, genitalia and guts. A team of Duke University scientists has tracked how this microbial evolution unfolded, using mathematical tools originally developed for geologists. The scientists…

Metabolism may be older than life itself and start spontaneously

A set of chemical reactions occurring spontaneously in Earth’s early chemical environments could have provided the foundations upon which life evolved. The discovery that a version of the Krebs cycle, which occurs in most living cells, can proceed in the absence of cellular proteins called enzymes suggests that metabolism is older than life itself. Metabolism…

On climate change, Scott Pruitt causes an uproar — and contradicts the EPA’s own website

Scott Pruitt, the nation’s top environmental official, strongly rejected the established science of climate change on Thursday, outraging scientists, environmentalists, and even his immediate predecessor at the Environmental Protection Agency. “I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact,…

Gene found to cause sudden death in young people

Researchers from Canada, South Africa and Italy have identified a new gene that can lead to sudden death among young people and athletes. The gene, called CDH2, causes arrhythmogenic right ventricle cardiomyopathy (ARVC), which is a genetic disorder that predisposes patients to cardiac arrest and is a major cause of unexpected death in seemingly healthy…

Neanderthal DNA contributes to human gene expression

The last Neanderthal died 40,000 years ago, but much of their genome lives on, in bits and pieces, through modern humans. The impact of Neanderthals' genetic contribution has been uncertain: Do these snippets affect our genome's function, or are they just silent passengers along for the ride? In Cell on February 23, researchers report evidence…
