The Hubble Space Telescope celebrated its 32nd year in orbit by premiering a stunning new Hubble image of a collection of five galaxies, known as Hickson Compact Group 40. Even after all these years, Hubble continues to uncover the mysteries of the universe. These are a few science achievements from Hubble’s latest year in orbit.
This week The World Economic Forum are highlighting 4 top stories – mass hunger from the Ukraine war, how businesses can help Ukraine, rejection of fossil fuels by consumers despite rising energy prices and robots that clean solar panels.
The World Economic Forum is the International Organization for Public-Private Cooperation. The Forum engages the foremost political, business, cultural and other leaders of society to shape global, regional and industry agendas. We believe that progress happens by bringing together people from all walks of life who have the drive and the influence to make positive change.
The war in Ukraine has sparked an energy crisis, as European countries attempt to cut ties with Russia. The team discusses what this means for the future of energy production and how it may speed up our pivot to renewable energy. They also explore the growing concerns at various nuclear sites in Ukraine, as some have been seized by the Russians, while others have been damaged during the conflict.
For the first time a virgin birth has taken place in a mammal – a female mouse has given birth without any input from a male. The team explains how CRISPR gene editing has been used to create embryos from unfertilised eggs.
As the Amazon rainforest becomes less resilient to drought, there are fears it may be passing a tipping point that could turn the whole system from forest into savannah. Earth system scientist Tim Lenton of the University of Exeter explains the devastating global impact this would have.
Taking a much-needed trip off the planet, the team discusses two stories from Mars, one from NASA’s Perseverance rover and another from China’s Zhurong rover. We also present an audio space-quiz you can take part in! Thanks to NASA/JPL-Caltech/LANL/CNES/CNRS/ISAE-Supaéro for the audio clips.
And legendary cosmologist Martin Rees shares his thoughts on the existence of extraterrestrial intelligence in the universe and the fascinating concept of ‘secular’ intelligent design.
On the pod are Rowan Hooper, Penny Sarchet, Matt Sparkes, Adam Vaughan and Richard Webb. To read about these stories and much more, subscribe at newscientist.com/podcasts.
We get the latest from Kyiv on the crisis in Ukraine and discuss the fallout from Chinese military incursions in Taiwanese airspace. Plus: Nasa’s space telescope reaches its destination and we visit a haunted house in Istanbul.
2021 was the busiest year yet for NASA in low-Earth orbit, we also made progress preparing for a flight test around the Moon, and had a very active year exploring space, studying Earth, testing technologies for next generation aircraft, and much more. Here’s a look back at those and other things we did this year at NASA. Download Link: https://go.nasa.gov/3yM3so2
The James Webb Space Telescope, a collaboration between NASA, the European Space Agency and the Canadian Space Agency, is set to launch later this month. Scientists say its technology makes it 100 times more powerful than the Hubble and could give it the ability to see back to the first galaxies in the universe. Illustration: Adele Morgan/WSJ
The Nature salary and satisfaction survey reveals researchers’ outlook, and NASA’s test of planetary defenses.
In this episode:
00:45 Salary and satisfaction survey
Like all aspects of life, scientific careers have been impacted by the pandemic. To get an insight into how researchers are feeling, Nature has conducted a salary and satisfaction survey. We hear from some of the respondents.
Careers Feature: Stagnating salaries present hurdles to career satisfaction
09:07 Research Highlights
The physics of a finger snap, and the surprisingly strong silk of jumping spiders.
Research Highlight: It’s a snap: the friction-based physics behind a common gesture
Research Highlight: High-speed spinning yields some of the toughest spider silk ever found
11:23 Briefing Chat
We discuss some highlights from the Nature Briefing. This time, the plans to smash a spacecraft into an asteroid, and how baby formula is changing to better resemble breast milk.
Chemistry World: The science of breast milk and baby formula
NASA introduced the space agency’s first planetary defense test mission, the Double Asteroid Redirection Test or DART, a spacecraft they plan to launch later this month on a mission to crash into an asteroid.
The surface of Venus is completely inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth’s and roasted by temperatures two times hotter than an oven. But was it always that way? Could Venus once have been a twin of Earth — a habitable world with liquid water oceans? This is one of the many mysteries associated with our shrouded sister world. 27 years have passed since NASA’s Magellan mission last orbited Venus. That was NASA’s most recent mission to Earth’s sister planet, and while we have gained significant knowledge of Venus since then, there are still numerous mysteries about the planet that remain unsolved. NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission hopes to change that. Video credit: NASA’s Goddard Space Flight Center
