On the basis of a unique global comparison of data from core samples extracted from the ocean floor and the polar ice sheets, AWI researchers have now demonstrated that, though climate changes have indeed decreased around the globe from glacial to interglacial periods, the difference is by no means as pronounced as previously assumed. Until now, it was believed that glacial periods were characterised by extreme temperature variability, while interglacial periods were relatively stable. The researchers publish their findings advanced online in the journal Nature.

New research led by CU Boulder shows that the changing topography of ice sheets in the Northern Hemisphere during the last Ice Age forced changes in the climate of Antarctica, a previously undocumented inter-polar climate change mechanism.

As the world grapples with the big problem of feeding 7.6 billion people, University of Lethbridge adjunct professor Dr. Wade Abbott of Agriculture and Agri-Food Canada and his team have detailed the smallest of metabolic reactions with the goal of improving food security, food safety and animal nutrition.

Pregnant women who take the pain killer ibuprofen in the first 24 weeks of their pregnancy may be reducing the store of eggs in the ovaries of their daughters.

The world’s fastest land animal, the cheetah, is a successful hunter not only because it is quick, but also because it can hold an incredibly still gaze while pursuing prey. For the first time, researchers have investigated the cheetah’s extraordinary sensory abilities by analyzing the speedy animal’s inner ear, an organ that is essential for maintaining body balance and adapting head posture during movement in most vertebrates. The study, published today in the journal Scientific Reports and led by researchers at the American Museum of Natural History, finds that the inner ear of modern cheetahs is unique and likely evolved relatively recently.

On Jan. 20, 2018, amateur astronomer Scott Tilley detected an unexpected signal coming from what he later postulated was NASA’s long-lost IMAGE satellite, which had not been in contact since 2005. On Jan. 30, NASA — along with help from a community of IMAGE scientists and engineers — confirmed that the signal was indeed from the IMAGE spacecraft. Whatever the next steps for IMAGE may be, the mission’s nearly six years in operation provided robust research about the space around Earth that continue to guide science to this day.

The remnants of Tropical Cyclone Fehi brought rain to New Zealand before it fizzled out. NASA and the Japan Aerospace Exploration Agency’s GPM core satellite provided a look at the rainfall from its vantage point in space.

Clostridium Difficile, or C. difficile, strikes fear into the hearts of many. This life-threatening infection, caused through contact with bacteria, can develop rapidly even under the watchful eye of hospital staff. In fact, it is often spread in health care facilitates or nursing homes due to proximity of the bacteria.

A new international study involving ANU has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that challenges a popular theory about how dwarf galaxies are spread around the Universe. 

Some of the smallest creatures on the planet — zooplankton — make the most widespread vertical migration of biomass on Earth. Billions of these animals move deeper into the ocean and away from the light during the day to avoid predators, and migrate up again in the dark of night to feed.
