Why some researchers think I'm wrong about social media and mental illness

News

  • A debate among social scientists is ongoing on whether social media is the primary cause of the teenage mental illness epidemic.
  • Critics argue that the evidence is not strong enough to support claims of harm.
  • Proponents argue that something significant is happening to the mental health of teenagers that began around 2012, with no alternative explanation.
  • Rates of mental illness and social media usage don't have a clear cause-and-effect relationship, but skeptics can't explain the epidemic as neatly as the SSM theory.
  • Skeptics demand a high level of skepticism grounded in "beyond reasonable doubt," which is inappropriate for civil cases.
  • Disagreement exists between scientists over the size of the correlation between social media use and mental health problems.
  • Social media may be particularly harmful to girls.
  • Researchers often focus on one causal model when turning a question into variables they can measure, which may obscure other potential causal pathways.

Qantas is bringing back Airbus A380s from the California desert

News

  • Qantas has retrieved their last Airbus A380 from the Victorville boneyard in California after almost 1000 days of storage due to the pandemic-induced grounding of long-haul aircraft.
  • Returning an A380 to service requires significant effort, including 4500 hours of manpower and the replacement of crucial parts, which led to delays for some airlines.
  • Qantas engineers spent two months per aircraft in the Mojave Desert to revive the A380s, which were wrapped to protect themselves from moisture, dust, and insects.
  • Although Qantas is close to bringing their A380s back to action, the airline does not expect international flying to return to pre-pandemic levels until at least 2024.
  • Qantas has heavily invested in kick-starting Australia's sustainable aviation fuel industry while struggling to meet its emissions-reduction goal of carbon neutrality by 2050.
  • Qantas has not yet announced a plan to replace its ageing fleet of A380s but expects to spend $US5 billion ($7.4 billion) on fleet investment over the next four years, including a dozen A350-1000s.

Industry Reactions

  • Qantas is bringing back Airbus A380s from storage in Southern California for flights from Sydney and Melbourne to Dubai due to high demand for flights from Australia to Europe.
  • Emirates, the largest owner of A380s, is asking for a bigger plane to meet high demand for flying, but none of the engine manufacturers are interested in developing new engines for the A380, putting the future of the plane in doubt.
  • The A380's expensive costs and reduced market demand have reduced its competitiveness compared to other wide-body planes, and engine problems have limited its capacity.
  • Boeing 737 Max MCAS issue is not the first time the aircraft has encountered issues, and Boeing will not have a 737/757 replacement for another 10-15 years, giving Airbus a competitive edge.
  • Passively colluding markets can lead to higher prices and reduced competition, and tacit collusion in the airplane industry could lead to higher profits.
  • The A380 may still be used as a cargo plane for outsized loads but lacks necessary features for general cargo use.
  • Airbus changed their focus from successful routes to the "we are the biggest" crown with the A380, but now has competitors for these routes with planes like A350, A321-XLR, and neo planes.
  • Hub airlines offer more frequency of flights, but passengers prefer airlines with multiple flights at varying times throughout the day.
  • Experts discuss solutions for aviation fuel to achieve carbon neutrality, such as biofuels, trees, and sustainable aviation fuels investment.

Building telescopes on the Moon could transform astronomy

News

  • Building telescopes on the Moon could transform astronomy
  • Lunar exploration is undergoing a renaissance with many missions planned, including NASA's Artemis program which aims to return humans to the lunar surface by the middle of the decade
  • The Moon offers advantages for observational astronomy with its stable surface and craters that receive no sunlight
  • The far side of the Moon is particularly attractive for radio astronomy as it is permanently shielded from radio signals generated by humans on Earth, making it probably the most "radio-quiet" location in the whole solar system
  • The lunar far side is also an ideal location for low-frequency radio astronomy, which can probe the structure of the early universe
  • The Moon's low gravity also enables the construction of much larger telescopes than is feasible for free-flying satellites
  • The cold, stable environment of permanently shadowed craters may also have advantages for instruments to detect gravitational waves and for studying solar wind and galactic cosmic rays
  • However, there is a tension between human activities on the lunar far side and unwanted radio interference, and plans to extract water-ice from shadowed craters might make it difficult for those same craters to be used for astronomy.

Industry Reactions

  • Building telescopes on the moon could revolutionize astronomy by providing higher sensitivity and spectrographic resolution.
  • High cost of building telescopes is justified in the hopes of making groundbreaking scientific discoveries, inspiring future generations, and driving technical innovation.
  • Scientific discovery's value cannot be quantified by $/unit and shares a high-cost, high-reward approach with fields like particle physics.
  • Military spending has historically driven scientific advancements.
  • Tangible benefits of funding scientific research include providing a framework for how technology operates, benefiting society through discoveries from unexpected research, and cultivating a highly-trained workforce.
  • Proposed telescope FOCAL could potentially provide otherwise impossible scientific measurements and is more important than settling on Mars.
  • NASA's Artemis program aims to build a radio telescope on the far side of the Moon, which has a radio-quiet environment and could produce higher-quality images than any observatory on Earth regarding the Big Bang's cosmic radiation.
  • Location of the telescope on the Moon overcomes one of the biggest difficulties of space-based telescopes because the lunar rock shields against most sources of high-frequency noise from satellites, man-made or natural.
  • Technical complications related to the Moon's environment, such as fine dust covering the hardware, thermal control, and communication problems with Earth, need to be solved by space engineers.
  • Communication with Mars could improve by using modern storage technology, Venus satellites, or a halo orbit at earth-moon L2, L4, or L5, but the moon is difficult to orbit due to the unevenness of gravity.
  • The actual existence and detection of "dark" matter and energy remains elusive, and using planets or asteroids for a gravity lensing effect is impractical due to the large focal point.
  • Discovery of mascons led to the study of their effect on spacecraft, and the discovery of "frozen orbits."
  • Telescope on the Moon presents more access and less risk for maintenance than telescopes like JWST that are too far for Hubble to observe it.
  • The comment section debates the likelihood and cost of a proposed lunar telescope project and the tendency to search for water in celestial bodies.
