Do plants talk to one another? Let’s get to the root of the situation!
Biology & Chemistry
Getting down to liquid helium temperatures (4K) may be fairly straight forward, but cooling below that requires taking advantage of quantum phenomena. In this video Associate Professor Andrea Morello from the University of New South Wales explains how ‘zero-point motion’ makes it possible to use Helium-3 and Helium-4 in a dilution fridge to get down to only thousandths of degrees above absolute zero.
Cooking may be more than just a part of your daily routine, it may be what made your brain as powerful as it is.
As the narrative goes, fat is bad. Well, it’s actually more nuanced than that. The type of fat you eat is more impactful on your health than the quantity. George Zaidan examines triglycerides, the varied molecules that make up fat, and how to identify which types of fat you are consuming.
The chemistry of the ocean is changing. Most climate change discussion focuses on the warmth of the air, but around one-quarter of the carbon dioxide we release into the atmosphere dissolves into the ocean. Dissolved carbon dioxide makes seawater more acidic—a process called ocean acidification—and its effects have already been observed: the shells of sea butterflies, also known as pteropods, have begun dissolving in the Antarctic.
This week’s SciShow news brings you discoveries involving two of the most exotic substances on Earth – the world’s rarest element and the world’s oldest water. Two great tastes that taste great together?
When art meets neuroscience, strange things happen.
Hank gives you the facts on stem cells – what they are, what they’re good for, where they come from, and how they’re used in medicine.
Does size really matter? It’s an age old question that finally has a scientific answer! Watch this DNews video as Trace tackles the HUGE-ly debated topic
There are a lot of ways to kill and be killed in the animal kingdom, but only a lucky few use the powers of venom. Not all are closely related, so how did they acquire the same defenses, where did venom come from, and how does it work? And what animals can kill you the most quickly?
Humans drew the short end of the toothbrush when it comes to our pearly whites’ longevity. Other animals such as reptiles and fish frequently lose and replace their teeth by growing new ones, but people are stuck with the same set of mature adult teeth their entire lives. If they lose a tooth–or all 32–dentures are usually the only option.
Some lucky animals are naturally endowed with bioluminescence, or the ability to create light. The firefly, the anglerfish, and a few more surprising creatures use this ability in many ways, including survival, hunting, and mating. Leslie Kenna investigates this magical glow – and our quest to replicate it.
Ever wondered if humans will ever be able to fly? Does stress really cause grey hair? And what exactly is the tingling feeling in our arms?
