Unwinding is Now a Scientific Way to Chill

Unwinding fibers could potentially be the base of a new cooling technique. (Photo : University of Texas) The commercial and industrial demand for cooling techniques and technologies are currently based on the thermodynamic principles of refrigeration cycles by compression and expansion.

Heat Will Drive Lower Crop Yields, Not Drought

Researchers forecasted the enormous losses for maize and spring wheat, but more resilient crops such as sorghum, which is half as sensitive to high temperature as maize, will experience less damage

Deadly Heatwave is Killing the Ocean

Heatwaves hit the worlds oceans likened to wildfire by Scientists. Extreme temperatures are killing the corals, seagrass and kelp and all of these have a great impact on the survival of humanity.

Can Magnetism Bend Heat And Sound? Study Reveals A New Dimension to Magnetic Fields

For many years researchers have sought to discover just how many uses magnetic fields can have. To date they have become essential in quantum computing, they are vital in medical imaging, and astronomers have even used natural magnetism to amplify the signals of light from far off supernovae and galaxies so that we here on Earth can see them hundreds or thousands of light-years away. But in a new study from researchers at Ohio State University, nanotechnologists have revealed that magnetic fields can impact our lives in far more real ways—controlling heat and sound waves that exhibit magnetic properties of their own.
