Scientists develop an energy-efficient strategy to reversibly change ‘spin orientation’ or magnetization direction in magnetite at room temperature — ScienceDaily

Over the last few decades, conventional electronics has been rapidly reaching its technical limits in computing and information technology, calling for innovative devices that go beyond the mere manipulation of electron current. In this regard, spintronics, the study of devices that exploit the “spin” of electrons to perform functions, is one of the hottest areas in applied physics. But, measuring, altering, and, in general, working with this fundamental quantum property is no mean feat.

Current spintronic devices — for example, magnetic tunnel junctions — suffer from limitations such as high-power consumption, low operating temperatures, and severe constraints in material selection. To this end, a team of scientists at Tokyo University of Science and the National Institute for Materials Science (NIMS), Japan, has recently published a study in ACS Nano, in which they present a surprisingly simple yet efficient strategy to manipulate the magnetization angle in magnetite (Fe3O

Even in the Bolivian Amazon, Average Human Body Temperature Is Getting Cooler | Smart News

If you’ve ever taken your temperature and wondered why your body wasn’t hovering at the supposedly normal 98.6 degrees Fahrenheit, a new study offers the latest in a growing body of evidence suggesting that oft-repeated figure might no longer be the norm.

Published last month in the journal Science Advances, the study finds the average body temperature among the Tsimane people, who live in the Bolivian Amazon rainforest, has dropped by almost a full degree over the last 16 years.

The dogma of 98.6 degrees Fahrenheitstarted in 1867 when a German doctor named Carl Wunderlich took the temperature of some 25,000 people in Leipzig and arrived at the figure. But several recent studies have suggested that people have cooled off over the last 150 years.

A study published earlier this year compiled hundreds of thousands of temperature readings in Palo Alto, California, and found the average body temperature among

Temperature rises with global warming could have major implications for child health, say researchers — ScienceDaily

Exposure to high temperatures in pregnancy is associated with an increase in adverse pregnancy outcomes, especially preterm birth and stillbirth, and among women in lower socioeconomic groups, finds a study published by The BMJ today.

Although the effects may appear small in size, the researchers say the findings “could have a major impact on public health as exposure to high temperatures is common and escalating.” Moreover, conditions such as preterm birth often have lifelong implications for affected newborns.

Increases in global temperatures raise concerns about heat impacts on health, especially in vulnerable groups such as the elderly, those living in poverty, and the chronically ill.

Previous evidence reviews have found associations between exposure to high temperatures and pregnancy outcomes, but have included few studies and have not assessed differences across population groups and by type of heat exposure.

So an international team of researchers set out to assess whether exposure

Researchers examine the decline in average body temperature among healthy adults over the past two decades

In the nearly two centuries since German physician Carl Wunderlich established 98.6°F (37 C) as the standard “normal” body temperature, it has been used by parents and doctors alike as the measure by which fevers—and often the severity of illness—have been assessed.


Over time, however, and in more recent years, lower body temperatures have been widely reported in healthy adults. A 2017 study among 35,000 adults in the United Kingdom found average body temperature to be lower (97.9°F / 36.6 C), and a 2019 study showed that the normal body temperature in Americans (those in Palo Alto, California, anyway) is about 97.5°F (36.4 C).

A multinational team of physicians, anthropologists and local researchers led by Michael Gurven, UC Santa Barbara professor of anthropology and chair of the campus’s Integrative Anthropological Sciences Unit, and Thomas Kraft, a postdoctoral

  • Superconductors are materials that effortlessly conduct electricity.
  • Until now, they’ve only worked at temperatures of minus 100 degrees Fahrenheit. 
  • But researchers recently found a superconductor that works at ambient temperatures when under immense pressure. They’re now trying to make it work without that pressure.
  • Widespread superconductors could give rise to high-speed floating trains, super-powered computers, and very cheap electricity.

Superconductors – materials that transport electricity with no energy lost – have until now only worked at extremely cold temperatures, from about -100 degrees Fahrenheit to the near-absolute zero of space. But this month, that changed.
