Offices Are Too Hot Or Too Cold – Is There A Better Way To Control Room Temperature?

In any office, home or other shared space, there’s almost always someone who’s too cold, someone who’s too hot – and someone who doesn’t know what the fuss around the thermostat is all about. Someone’s too hot and someone’s too cold. Collage by The Conversation, combining images by Monika Wisniewska and Antonio Guillem/Shutterstock.com, CC BY-ND Most often, building owners and operators find out how their heating and cooling systems are doing by asking occupants if they’re comfortable or whether they want to be cooler or warmer. However, everyone has a different ideal temperature at any given time, based on all sorts of factors, including their age and gender, their physical activity level, what they’re wearing and even how much stress they’re feeling at the moment. This is a complex prob...

Oxford-AstraZeneca Vaccine Doesn’t Require Supercold Temperature, And Is Cheaper Than Pfizer’s And Moderna’s

The biopharmaceutical company AstraZeneca has released data on what is now the third promising vaccine candidate against COVID-19 – and it has several advantages over those of its competitors, Pfizer and Moderna. On Monday, AstraZeneca released interim analysis of its phase 3 trial data of 23,000 volunteers from the U.K. and Brazil. These results show that the test vaccine is between 70% and 90% effective in stopping COVID-19, depending on the vaccine doses administered. Although less effective than the reported results from the Pfizer or Moderna COVID-19 vaccine candidates, this vaccine is still more effective than annual influenza vaccines that reduce the risk of flu by between 40% and 60%. Notably none of the vaccinated participants needed hospitalizations or reported severe disease. ...

Physicists hunt for room-temperature superconductors that could revolutionize the world’s energy system

Waste heat is all around you. On a small scale, if your phone or laptop feels warm, that’s because some of the energy powering the device is being transformed into unwanted heat. On a larger scale, electric grids, such as high power lines, lose over 5% of their energy in the process of transmission. In an electric power industry that generated more than US$400 billion in 2018, that’s a tremendous amount of wasted money. Globally, the computer systems of Google, Microsoft, Facebook and others require enormous amounts of energy to power massive cloud servers and data centers. Even more energy, to power water and air cooling systems, is required to offset the heat generated by these computers. Where does this wasted heat come from? Electrons. These elementary particles of an atom move arou...
