Nearsightedness is also known as myopia. DepositPhotos
This article was originally featured on The Conversation.
Myopia, or the need for corrected vision to focus or see objects at a distance, has become a lot more common in recent decades. Some even consider myopia, also known as nearsightedness, an epidemic.
Optometry researchers estimate that about half of the global population will need corrective lenses to offset myopia by 2050 if current rates continue–up from 23% in 2000 and less than 10% in some countries.
The associated health care costs are huge. In the United St ..read more

Similar activity will likely increase as the sun nears its 'solar maximum.'. Credit: NASA/SDO/AIA
Earlier this week, NASA’s Solar Dynamics Observatory (SDO) recorded a rarely seen event—four nearly-simultaneous flare eruptions involving three separate sunspots, as well as the magnetic filament between them. But as impressive as it is, the event could soon pose problems for some satellites and spacecraft orbiting Earth, as well as electronic systems here on the ground.
It may seem like a massive ball of fiery, thermonuclear chaos, but there’s actually a fairly predictable rhythm to the sun. Si ..read more

Most grocery store patrons take for granted just what it takes to transport a humble sweet potato out of the ground and into a shopping basket. The slightly-sweet red root vegetable can come in various sizes and flavor profiles but consumers have come to expect a level of consistency.

It’s ‘spider’ season on the Red Planet. There are no actual spiders on Mars–that we know of–but arachnid-shaped black spots dot some parts of our celestial neighbor every spring.
[Related: Mars’s mascara-like streaks may be caused by slush and landslides.]
The European Space Agency (ESA) released new images of these seasonal eruptions in a formation called Inca City in Mars’ southern polar region.
How do Martian ‘spiders’ form?
Mars has four distinct seasons, sim ..read more

When OceanGate’s under-tested Titan submersible went missing last summer, it captured the attention of millions worldwide. Authorities frantically scoured the North Atlantic Ocean for days only to eventually determine the small vessel had catastrophically imploded, killing its five passengers instantly. The tragic incident doesn’t appear to have actually slowed demand or interest in the vessels among its audience of passionate, and often wealthy, underwater exploration enthusiasts. Th ..read more

In about 5 billion years, our Sun will run out of fuel and expand, possibly engulfing Earth. These end stages of a star’s life can be utterly beautiful as is the case with this planetary nebula called the Helix Nebula. Astronomers study these objects by looking at all kinds of light, including X-rays that the Chandra X-ray Observatory sees. X-ray: NASA/CXC/SAO; UV: NASA/JPL-Caltech/SSC; Optical: NASA/ STScI/M.
