Nina DiSesa: What would you like your legacy to be?

Nina DiSesa: Well, I always from most of my career I always wanted to be seen as a client advocate of in the person who could really understand the value of a brand into make a brand worthwhile, but legally I have kind of switched over to what I want to work what I want to be remembered for and I think I would rather be remembered now for a champion of women, that’s why I wrote this book is …. women are always coming to me for advise when they are having the difficult time not just but remember with people who are in general in the office and I have always tried to council them, and I wrote this book to kind of get a lot of those things in print so that I could reach a wider audience and also when I am not available anymore and that there is some place for somebody to do to kind of figure out what to do next. So I would like to continue to do the job that on doing from McCann Erickson, but I would also like to continue my role as a mentor to women who are frustrated that not getting as far as they have like to go in the boys clubs so any other industry really. And if I could do that for the next 15 or 20 years I would be happy. Recorded on: 2/29/08

DiSesa hopes that she is remembered for fighting for women in the workplace.

    • A new paper reveals a meteorite that crashed in Michigan in 2018 contained organic matter.
    • The findings support the panspermia theory and could explain the origins of life on Earth.
    • The organic compounds on the meteorite were well-preserved.

    This is what aliens would 'hear' if they flew by Earth

    A Mercury-bound spacecraft's noisy flyby of our home planet.

    Surprising Science
    • There is no sound in space, but if there was, this is what it might sound like passing by Earth.
    • A spacecraft bound for Mercury recorded data while swinging around our planet, and that data was converted into sound.
    • Yes, in space no one can hear you scream, but this is still some chill stuff.

    First off, let's be clear what we mean by "hear" here. (Here, here!)

    Sound, as we know it, requires air. What our ears capture is actually oscillating waves of fluctuating air pressure. Cilia, fibers in our ears, respond to these fluctuations by firing off corresponding clusters of tones at different pitches to our brains. This is what we perceive as sound.

    All of which is to say, sound requires air, and space is notoriously void of that. So, in terms of human-perceivable sound, it's silent out there. Nonetheless, there can be cyclical events in space — such as oscillating values in streams of captured data — that can be mapped to pitches, and thus made audible.

    BepiColombo

    The European Space Agency's BepiColombo spacecraft took off from Kourou, French Guyana on October 20, 2019, on its way to Mercury. To reduce its speed for the proper trajectory to Mercury, BepiColombo executed a "gravity-assist flyby," slinging itself around the Earth before leaving home. Over the course of its 34-minute flyby, its two data recorders captured five data sets that Italy's National Institute for Astrophysics (INAF) enhanced and converted into sound waves.

    Into and out of Earth's shadow

    In April, BepiColombo began its closest approach to Earth, ranging from 256,393 kilometers (159,315 miles) to 129,488 kilometers (80,460 miles) away. The audio above starts as BepiColombo begins to sneak into the Earth's shadow facing away from the sun.

    The data was captured by BepiColombo's Italian Spring Accelerometer (ISA) instrument. Says Carmelo Magnafico of the ISA team, "When the spacecraft enters the shadow and the force of the Sun disappears, we can hear a slight vibration. The solar panels, previously flexed by the Sun, then find a new balance. Upon exiting the shadow, we can hear the effect again."

    In addition to making for some cool sounds, the phenomenon allowed the ISA team to confirm just how sensitive their instrument is. "This is an extraordinary situation," says Carmelo. "Since we started the cruise, we have only been in direct sunshine, so we did not have the possibility to check effectively whether our instrument is measuring the variations of the force of the sunlight."

    When the craft arrives at Mercury, the ISA will be tasked with studying the planets gravity.

    Magentosphere melody

    The second clip is derived from data captured by BepiColombo's MPO-MAG magnetometer, AKA MERMAG, as the craft traveled through Earth's magnetosphere, the area surrounding the planet that's determined by the its magnetic field.

    BepiColombo eventually entered the hellish mangentosheath, the region battered by cosmic plasma from the sun before the craft passed into the relatively peaceful magentopause that marks the transition between the magnetosphere and Earth's own magnetic field.

    MERMAG will map Mercury's magnetosphere, as well as the magnetic state of the planet's interior. As a secondary objective, it will assess the interaction of the solar wind, Mercury's magnetic field, and the planet, analyzing the dynamics of the magnetosphere and its interaction with Mercury.

    Recording session over, BepiColombo is now slipping through space silently with its arrival at Mercury planned for 2025.

    Should facial recognition software be banned on college campuses?

    • Students say they were identified with facial recognition technology after a protest at the University of Miami; campus police claim this isn't true.
    • Over 60 universities nationwide have banned facial recognition; a few colleges, such as USC, regularly use it.
    • Civil rights groups in Miami have called for the University of Miami to have talks on this topic.
