How big does the Saguaro cactus get? 🌵This tree-like giant typically reaches heights of 40 ft (12.2 m), but the record-holder was a specimen that grew more than 78 ft (23.8 m) tall! Expanding to store water in its fleshy stem, this cactus can weigh more than one ton when mature.

The RUBISCO enzyme plays a critical role in photosynthesis. But it’s not always very efficient.

Scientists want to change that.

The amount of water stored in more than half of the largest lakes and reservoirs worldwide is declining, a recent Science study finds.

The results underscore the importance of better water management to protect essential ecosystem services. https://t.co/QcRMo6yhqg

A survey from 2017 suggests that 1 in 5,000 clovers has four-leaves. But they are usually found in clusters, so if you find one odds are good you'll find more.

Scientists have generated the first complete map of the brain of a small insect. The map shows all 3,016 neurons and 548,000 synapses tightly packed in a young fruit fly's brain, which is smaller than a poppy seed https://t.co/4806X4B7Cb

For the first time, scientists have observed direct geological evidence of an active volcano on Venus. 🌋

The @UAFGI and JPL team made the discovery after scouring archival radar images taken by @NASA’s Magellan mission more than 30 years ago. https://t.co/CTYYBFzAJl

Deer antlers can grow up to 2.75 cm per day. How do they achieve such rapid and complete regeneration?

A new Science study identifies a population of stem cells are responsible for this speedy cycle.
