  • Measuring the tRNA world
    on February 26, 2021 at 7:04 pm

    Transfer RNAs (tRNAs) deliver specific amino acids to ribosomes during translation of messenger RNA into proteins. The abundance of tRNAs can therefore have a profound impact on cell physiology, but measuring the amount of each tRNA in cells has been limited by technical challenges. Researchers have now overcome these limitations with mim-tRNAseq, a method that can be used to quantify tRNAs in any organism and will help improve our understanding of tRNA regulation in health and disease.

  • NASA-Funded Network Tracks the Recent Rise and Fall of Ozone-Depleting Pollutants
    on February 17, 2021 at 4:50 pm

    A short-lived resurgence in the emission of ozone-depleting pollutants in eastern China will not significantly delay the recovery of Earth’s protective “sunscreen” layer, according to new research published Feb. 10 in Nature. Stratospheric ozone, also known as Earth’s ozone layer, helps shield us from the Sun’s harmful Ultraviolet (UV) rays. Compounds like CFC-11 (Trichlorofluoromethane, also known as Freon-11), a chemical once considered safe and widely used as a refrigerant and in the production of insulation for buildings, rise to the stratosphere after emission on Earth’s surface. Once in the atmosphere, CFCs are broken down by the UV light and result in the destruction of ozone molecules, both reducing stratospheric ozone concentrations globally and contributing to a “hole” in the layer that appears over Antarctica in the spring. NASA computer models help scientists identify an uptick in atmospheric emissions of an ozone-depleting gas called CFC-11. NASA and the National Oceanic and Atmospheric Administration (NOAA) work together as part of a long-running research partnership to monitor emissions of stratospheric ozone and to support ozone scientists at MIT and the University of Bristol.

  • Under climate stress, human innovation set stage for population surge
    on February 26, 2021 at 5:12 pm

    Aridification in the central plains of China during the early Bronze Age did not cause population collapse, a result that highlights the importance of social resilience to climate change. Instead of a collapse amid dry conditions, development of agriculture and increasingly complex human social structures set the stage for a dramatic increase in human population around 3,900 to 3,500 years ago.

  • Stark warning: Combating ecosystem collapse from the tropics to the Antarctic
    on February 26, 2021 at 3:37 pm

    Eminent scientists warn that key ecosystems around Australia and Antarctica are collapsing, and propose a three-step framework to combat irreversible global damage.

  • Gulf Stream System at its weakest in over a millennium
    on February 25, 2021 at 4:33 pm

    Never before in over 1000 years the Atlantic Meridional Overturning Circulation (AMOC), also known as Gulf Stream System, has been as weak as in the last decades. Researchers compiled proxy data, reaching back hundreds of years to reconstruct the AMOC flow history. They found consistent evidence that its slowdown in the 20th century is unprecedented in the past millennium.

Video: Kim Cobb, Ph.D., a climate scientist and professor at the Georgia Institute of Technology, and one of the first professors to teach out of a” living building”, shares how we as individuals can lessen the impact of climate change, and it isn’t recycling! Little changes in our work and personal lives can have a tremendous impact toward saving our planet. Kim Cobb’s research uses observations of past and present climate to advance our understanding of future climate change impacts. She received her B.A. from Yale University in 1996, and her Ph.D. in Oceanography from the Scripps Institute of Oceanography in 2002. She spent two years at Caltech in the Department of Geological and Planetary Sciences before joining the faculty at Georgia Tech in 2004. Kim has sailed on multiple oceanographic cruises to the deep tropics and led caving expeditions to the rainforests of Borneo in support of her research. Kim has received numerous awards for her research, most notably a NSF CAREER Award in 2007, and a Presidential Early Career Award for Scientists and Engineers in 2008. She is honored to be a Lead Author for the IPCC Sixth Assessment Report. As a mother to four, Kim is a strong advocate for women in science, and champions diversity and inclusion n all that she does. She is also devoted to the clear and frequent communication of climate change to the public through speaking engagements and social media. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
