A new breakthrough in biology allows scientists to grow food without sunlight

Photosynthesis can be considered one of nature’s superpowers, but it’s surprisingly inefficient, with only about 1 percent of the energy found in sunlight making it inside the plant. Now, scientists at UC Riverside and the University of Delaware say they have found a method to bypass the need for biological photosynthesis, allowing them to create …

Celestron Advanced VX 8 Edge HD telescope full review

The Celestron Advanced VX 8-inch EdgeHD is a versatile telescope system for intermediate to advanced amateur astronomers, but still small and lightweight enough to transport easily for observing out in the country. The 8-inch aperture is enough to view and photograph all types of celestial objects, and the computerized equatorial mount makes it easy to …

New study solves long-standing mystery of what may have triggered ice age

At the beginning of the last ice, local mountain glaciers grew and formed large ice sheets, like the one seen here in Greenland, that covered much of today’s Canada, Siberia, and Northern Europe. Credit: Annie Spratt/Unsplash A new study led by University of Arizona researchers may have solved two mysteries that have long puzzled paleo-climate …

SpaceX installs Super Heavy booster on launch mount with giant robot arms

SpaceX has transported the most powerful rocket booster ever assembled to its Starbase orbital launch site (OLS) and used giant robotic arms to install it. It’s not the first such trip for Starship’s Super Heavy first stage in general, nor for this specific booster, which is known as Booster 7 or B7. Booster 7 first …

Seismic waves from earthquakes reveal changes in the Earth’s outer core

The blue path illustrates a core-penetrating seismic wave moving through a region in the outer core, where the seismic speed has increased because a low-density flow has moved into the region. Credit: Ying Zhou In May 1997, a large earthquake shook the Kermadec Islands region in the South Pacific Ocean. A little over 20 years …

Octopus brain and human brain share the same ‘jumping genes’

Drawing of an octopus. Credit: Gloria Ros The octopus is an exceptional organism with an extremely complex brain and cognitive abilities that are unique among invertebrate. So much so that in some ways it has more in common with vertebrates than with invertebrates. The neural and cognitive complexity of these animals could originate from a …
