Podcasts about organic molecules

NASA's Perseverance rover has accidentally detected a rock containing sulphur in it. This discovery could turn out to be the first biosignature on Mars. ThePrint #̦PureScience, Sandhya Ramesh explains the findings and implications.

The Perseverance Rover has dug up a diverse set of molecules that are exciting astrobiologists. There's more talk about UAPs but still no actual science to back anything up... yet. Also. the JWST has captured another amazing photo. The Ariane 5's retirement is causing problems for the ESA. And an exoplanet with titanium clouds has been discovered.

Justin Spilker and his colleagues at Texas A&M University have detected the oldest and most distant organic molecules in the known Universe using the James Webb Space Telescope. Justin joins Planetary Radio to talk about the discovery and what it means for our understanding of star formation in the early Universe. We also share what to spot in the night sky this week and pay homage to the first women in space in this week's What's Up.

Organic molecules dissolved in rivers, lakes, seas and oceans are essential to plant and animal life. Some of these molecules are also degraded and enter a complex cycle of carbon, nitrogen and sulphur containing compounds. Surprisingly, scientists currently have a limited understanding of the fate of these molecules. Dr Daisuke Minakata and his colleagues from Michigan Technological University are involved in an ambitious programme to overcome this critical knowledge gap.

Dr. Jung-Mo Ahn, Associate Professor of Chemistry, University of Texas at Dallas September 14, 2022 In this episode, we discuss the use of small molecules as targeted treatments to interrupt the regulatory pathways responsible for cancer growth, neurodegenerative diseases, and other conditions, with relatively minimal off-target effects.

Complex Organic Molecules Formation in Cold Cores on Stochastically Heated Grains by Long-Fei Chen et al. on Monday 12 September We investigate the roles of stochastic grain heating in the formation of complex organic molecules (COMs) in cold cores, where COMs have been detected. Two different types of grain-size distributions are used in the chemical models. The first one is the MRN distribution, and the second one considers grain coagulation to study its effects on the chemical evolution in these environments. The macroscopic Monte Carlo method is used to perform the two-phase chemical model simulations. We find that (1) grain coagulation can affect certain gas-phase species, such as CO$_2$ and N$_2$H$^+$, in the cold core environments, which can be attributed to the volatile precursors originating from the small grains with temperature fluctuations; (2) grains with radii around 4.6 $times$ 10$^{-3}$ $mu$m contribute most to the production of COMs on dust grains under cold core conditions, while few species can be formed on even smaller grains with radii less than 2 $times$ 10$^{-3}$ $mu$m; (3) COMs formed on stochastically heated grains could help explain the observed abundances of gas-phase COMs in cold cores. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.05190v1

Don't get too excited, the discovery is not a confirmation that life once existed on Mars. Learn more about your ad choices. Visit megaphone.fm/adchoices

In just over one year on July 26, 2020, the launch window for the European Space Agency's Mars rover (recently named Rosalind Franklin) will open. Once the mission lands on Mars, the public will have access to daily images and information about the precise location of the rover,   Jorge Vago, PhD is a project scientist on the Rosalind Franklin rover mission, and he joins the podcast to provide a glimpse into what they hope to discover, how they hope to discover it, and how this mission will be unlike any other.   Dr. Vago explains that, unlike previous missions to Mars, this one will not only explore over a half billion years further into the past, but will also drill significantly deeper than ever before—up to two meters as opposed to five to ten centimeters.   By positioning themselves in a place to study Mars in its infancy and by employing the novel strategy of digging deeper to reach samples which have been protected from cosmic radiation, they hope to collect samples which will later--after exhaustive analyses and scrutiny--allow them to announce the existence of organic molecules and the possibility of life on Mars.   Catch all the details by tuning in, and visit exploration.esa.int to learn more.

The Podcast is designed to give an overview to the 4 very important Organic Molecules in Biology.

Ginger contains a cocktail of different molecules. The different molecules in dried, cooked and fresh ginger lead to different flavours.

Line Drawing for Organic Molecules

Transcript: In addition to being built up from smaller pieces by natural chemical reactions, organic molecules were brought to Earth by impacts early in the Earth’s history. Meteors have been shown to contain amino acids, a significant number of them, and other complex molecules. Complex molecules and organic material therefore can form and survive in deep space and can probably survive in the interior of an impacting object when it lands on the Earth. Thus, especially early in the Earth’s history, asteroids, comets, and meteors must have deposited a lot of organic material on the Earth’s surface. An extension of this idea which is a little more radical, is called directed panspermia, the idea that complex organic materials came to the Earth from far beyond the solar system as the Earth and the Sun and all the planets travel through interstellar material. There is no direct evidence that life origins come from beyond the solar system. However we have the case of Martian meteorites which can travel to us from Mars. Material traveling around the inner solar system could have transcribed and brought early organic material. In a sense, we might all be Martians if Martian meteorites with early life forms had seeded life on Earth. Nobody knows if this is a likely scenario yet.
