A massive effort to ‘hand-map’ undocumented roads has revealed the staggering extent of illegal or informal thoroughfares cut through forests of Indonesia, Malaysia, and New Guinea. Using satellite imagery, researchers from Australia and Indonesia measured 1.37 million kilometers (851,000 miles) of thoroughfare – between three and seven times longer than the roads officially recorded in

Superconductivity continues to revolutionize technology in so many ways. While some technological advances rely on finding ways to encourage zero-resistance currents at warmer temperatures, engineers are also considering better ways of fine-controlling the super-efficient flow of electrons. Unfortunately, many processes that would work just fine for run-of-the-mill electronics, such as the application of external magnetic

Bumblebees can surprisingly withstand days underwater, according to a study published Wednesday, suggesting they could withstand increased floods brought on by climate change that threaten their winter hibernation burrows. The survival of these pollinators that are crucial to ecosystems is “encouraging” amid worrying global trends of their declining populations, the study’s lead author Sabrina Rondeau

Climate change caused by CO2 emissions already in the atmosphere will shrink global GDP in 2050 by about US$38 trillion, or almost a fifth, no matter how aggressively humanity cuts carbon pollution, researchers said Wednesday. But slashing greenhouse gas emissions as quickly as possible remains crucial to avoid even more devastating economic impacts after mid-century,

Tardigrades are possibly the most indestructible animal on Earth. These microscopic little beasties can take almost anything humans throw at them, and waddle away perfectly intact on their eight stubby little legs. The strategies behind these feats of superheroic survival are multiple, from a damage suppressor protein that literally protects their DNA, to a dehydrated,

Scientists have discovered a species of marine algae that contains an organelle capable of harvesting nitrogen from the atmosphere – an ability previously thought to be the exclusive domain of certain symbiotic bacteria. The international team of researchers behind the discovery believe the algae’s talent originated from an endosymbiotic relationship, where a nitrogen-fixing cyanobacterium was

It’s an exciting time for the fields of astronomy, astrophysics, and cosmology. Thanks to cutting-edge observatories, instruments, and new techniques, scientists are getting closer to experimentally verifying theories that remain largely untested. These theories address some of the most pressing questions scientists have about the Universe and the physical laws governing it – like the
