Comfy – a new app that solves the No. 1 complaint about offices



You go to work on a hot summer day, but as soon as you sit at your desk, your are freezing. Or it’s winter and the heater keeps you too hot. The heating and cooling system is designed to keep you comfortable but it’s not doing a very good job, and it wastes massive amounts of energy in the process.

Cold caps may prevent hair loss during chemotherapy

Hospital staff help a patient put on a cold cap.

What is the first thing most patients undergoing chemotherapy want to know? Oncologist Susan Melin of the Wake Forest Baptist Medical Center in North Carolina told the Associated Press that often, her patients ask first about hair loss. “It’s not, ‘Is this going to cure me?’ It’s, ‘Am I going to lose my hair?'” she said.

Researchers achieve temperatures colder than absolute zero

When heated atoms can move with different levels of energy, from low to high. With positive temperatures (blue), atoms more likely occupy low-energy states than high-energy states, while the opposite is true for negative temperatures (red).

The coldest temperature possible is most often thought to be absolute zero.  Researchers have now shown they can achieve even lower temperatures for a strange realm of “negative temperatures.”

Yawning cools your brain: study


People yawned almost twice as much in winter, when their body temperature was higher than the air around them.

The brain is like a computer and works best when it is cool, but putting too great a strain on it can lead to overheating which reduces its ability to process information. Yawning is not just a sign of tiredness or boredom – it is the body’s method of keeping our brain cool, scientists have found.

Earth’s ‘missing’ heat may be hiding deep in oceans


The world temperature should have risen more than it did but where was the heat going?

The mystery of Earth’s missing heat may have been solved: it could lurk deep in oceans, temporarily masking the climate-warming effects of greenhouse gas emissions, researchers reported on Sunday.

Is it too late to turn the tides on rising sea levels?


If sea levels rose to where they were during the Last Interglacial Period, large parts of the Gulf of Mexico would be under water (red areas),

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean levels continue to rise long after warming of the atmosphere has leveled off.
