Unusual molecule found in atmosphere on Saturn’s moon Titan

Published

on

Saturn’s largest moon, Titan, is the only moon in our solar system that has a thick atmosphere. It’s four times denser than Earth’s. And now, scientists have discovered a molecule in it that has never been found in any other atmosphere, CNN has reported.

The particle is called cyclopropenylidene, or C3H2, and it’s made of carbon and hydrogen. This simple carbon-based molecule could be a precursor that contributes to chemical reactions that may create complex compounds. And those compounds could be the basis for potential life on Titan, the CNN report says.

The molecule was first noticed as researchers used the Atacama Large Millimeter/submillimeter Array of telescopes in Chile. This radio telescope observatory captures a range of light signatures, which revealed the molecule among the unique chemistry of Titan’s atmosphere.

The study published earlier this month in the Astronomical Journal.

“When I realized I was looking at cyclopropenylidene, my first thought was, ‘Well, this is really unexpected,’” said lead study author Conor Nixon, planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement.

Cyclopropenylidene has been detected elsewhere across our galaxy, mainly in molecular clouds of gas and dust including the Taurus Molecular Cloud. This cloud, where stars are born, is located 400 light-years away in the Taurus constellation. In these clouds, temperatures are too cold for many chemical reactions to occur.

Cyclopropenylidene has now been detected only in the Taurus Molecular Cloud and in the atmosphere of Titan.

But finding it in an atmosphere is a different story. This molecule can react easily when it collides with others to form something new. The researchers were likely able to spot it because they were looking through the upper layers of Titan’s atmosphere, where the molecule has fewer gases it can interact with.

“Titan is unique in our solar system,” Nixon said. “It has proved to be a treasure trove of new molecules.”

Cyclopropenylidene is the second cyclic or closed-loop molecule detected at Titan; the first was benzene in 2003. Benzene is an organic chemical compound composed of carbon and hydrogen atoms. On Earth, benzene is found in crude oil, is used as an industrial chemical and occurs naturally in the wake of volcanoes and forest fires.

Cyclic molecules are crucial because they form the backbone rings for the nucleobases of DNA, according to NASA.

“The cyclic nature of them opens up this extra branch of chemistry that allows you to build these biologically important molecules,” said study coauthor Alexander Thelen, an astrobiologist at Goddard, in a statement.

When the researchers discovered cyclopropenylidene in Titan’s atmosphere, they looked over data captured by NASA’s Cassini mission. The spacecraft performed 127 close flybys of Titan between 2004 and 2017. Cassini’s mass spectrometer detected a chemical signature of the same molecule, the researchers found.

“It’s a very weird little molecule, so it’s not going be the kind you learn about in high school chemistry or even undergraduate chemistry,” said c. Malaska was not involved with this study, but he researches Titan.

“Every little piece and part you can discover can help you put together the huge puzzle of all the things going on there.”

And discovering cyclopropenylidene on Titan adds to the moon’s intrigue.

US sports envoys to Lanka to champion youth development

Published

on

The U.S. Embassy in Colombo welcomed the U.S. Sports Envoys to Sri Lanka, former National Basketball Association (NBA) and Women’s National Basketball Association (WNBA) players Stephen Howard and Astou Ndiaye, from June 8 through 14.

The Public Diplomacy section of the U.S. Embassy said that it would launch a weeklong basketball program intended to harness the unifying power of sports, made possible through collaboration with Foundation of Goodness and IImpact Hoop Lab.

While in Sri Lanka, Howard and Ndiaye, both retired professional basketball players, will conduct a weeklong program, Hoops for Hope: Bridging Borders through Basketball.  The Sports Envoys will lead basketball clinics and exhibition matches and engage in leadership sessions in Colombo and Southern Province for youth aged 14-18 from Northern, Uva, Eastern and Western Provinces, offering skills and leadership training both on and off the court.  The U.S. Envoys will also share their expertise with the Sri Lanka Basketball Federation, national coaches, and players, furthering the development of basketball in the country.  Beyond the clinics, they will collaborate with Sri Lankan schoolchildren to take part in a community service project in the Colombo area.

“We are so proud to welcome Stephen and Astou as our Sports Envoys to Sri Lanka, to build on the strong people-to-people connections between the United States and Sri Lanka,” said U.S. Ambassador Julie Chung.  “The lessons that will be shared by our Sports Envoys – communication, teamwork, resilience, inclusion, and conflict resolution – are essential for leadership development, community building, equality, and peace. The U.S. Sports Envoy program is a testament to our belief that sports can be a powerful tool in promoting peace and unity.”

SJB Colombo District MP Mujibur Rahuman in parliament demanded to know from the government the reasons for CEB suspending the leave of all its employees until further notice from Thursday.

MP Rahuman said that the CEB has got an acting General Manager anew and the latter yesterday morning issued a circular suspending leave of all CEB employees with immediate effect until further notice.

“We demand that Minister Kanchana Wijesekera should explain this to the House. This circular was issued while this debate on the new Electricity Amendment Bill was pending. There are many who oppose this Bill. The Minister must tell parliament the reason for the urge to cancel the leave of CEB employees,” the MP said.However, Speaker Mahinda Yapa Abeywardena prevented Minister Wijesekera responding to the query and said that the matter raised by MP Rahuman was not relevant.

Saman Jayawickrama (Retd) – Secretary, CIPM Sri Lanka, Dr Dilanjalee Weerathunga – Co Chairperson of the Symposium

The Chartered Institute of Personnel Management (CIPM) successfully concluded the 8th Annual CIPM Symposium, which took place on 31st May 2024. Themed “Nurturing the Human Element—Redefining HRM in a Rapidly Changing World,” the symposium underscored the pivotal role of human resource management (HRM) in today’s dynamic global landscape. Since its inception in 1959, CIPM has been dedicated to advancing the HR profession through education, professional development, and advocacy, solidifying its position as Sri Lanka’s leading professional body for HRM.

Ken Vijayakumar, the President of the CIPM, graced the occasion as the chief guest. The symposium commenced with the welcome address by the Chairperson, Prof. Arosha Adikaram, followed by the Web Launch of the Symposium Proceedings and Abstract Book by the CIPM President. The event featured distinguished addresses, including a speech by Chief Guest Ken Vijayakumar, President of CIPM, and an address by Guest of Honor Shakthi Ranatunga, Chief Operating Officer of MAS Holdings Pvt. Ltd., Sri Lanka.

The symposium also featured an inspiring keynote address by Prof. Mario Fernando, Professor of Management and Director of the Centre for Cross Cultural Management (CCCM) at the University of Wollongong, Australia.

Vote of Thanks of the inauguration session was delivered by Dr. Dillanjani Weeratunga, Symposium Co-chair.

The symposium served as a comprehensive platform for researchers to present their findings across a wide range of critical topics in HRM. These included Cultural Diversity and Inclusion, Talent Development and Retention, Ethical Leadership and Corporate Social Responsibility, Adapting to Technological Advancements, Mental Health and Well-being at Work, Global Workforce Challenges, Employee Empowerment, and Reskilling and Upskilling.

The plenary session was led by Prof. Wasantha Rajapakse. Certificates were awarded to the best paper presenters during the valedictory session, followed by a vote of thanks delivered by Kamani Perera, Manager of Research and Development.

The annual symposium of CIPM was a truly inclusive event, attracting a diverse audience that spanned undergraduates, graduates, working professionals, research scholars and lecturers. This widespread interest highlights the symposium’s significance in the field of HRM, offering a unique opportunity for everyone to network and learn from scholarly brains.The CIPM International Research Symposium was sponsored by Hambantota International Port, Sri Lanka Institute of Information Technology (SLIIT), E B Creasy & Co.
