Do all people with obesity have increased risk of disease?

The process by which our cells convert the food we eat into the energy required for various bodily functions is known as metabolism, and it is essential for our survival. However, if we consume more food than our body needs, we may gain weight and potentially become obese. Obesity can affect the functioning of our cells and organs and increase the risk of metabolic diseases, including type 2 diabetes and cardiovascular issues. These metabolic diseases are widespread in today's world, prompting national and global health authorities to focus on preventing and treating obesity and related health conditions.

Nerves, Pain and Consciousness

We all experience pain at some point, and it's like a built-in alarm system, letting us know when something's wrong and teaching us to avoid certain actions. Normally, when we get hurt, like with a cut or a bump, special nerve fibers in our body send quick electrical messages to our brain, making us feel pain. Sometimes, though, pain can happen for no apparent reason, like when these nerve fibers get damaged. Think of it as a glitch in the system! Luckily, there are medicines that can help. Some stop those electrical messages before they reach the brain, while others make it so the brain can't really "read" those messages properly. This article is all about how pain works in our bodies, how our brain turns it into the feeling we know, and how certain meds can make it all better.

New Class of Titanium Alloy

Titanium alloys are advanced lightweight materials, indispensable for many critical applications. The mainstay of the titanium contain aluminium and vanadium. Scientists have been working on harnessing two of the most powerful stabilising elements and strengtheners for titanium alloys, oxygen and iron, which are readily abundant.

Oobleck’s weird behavior is now predictable

Oobleck is a non-newtonian fluid. That is, it acts like a liquid when being poured, but like a solid when a force is acting on it. You can grab it and then it will ooze out of your hands. Make enough Oobleck and you can even walk on it! MIT engineers develop a model that predicts how the cornstarch-water mixture turns from liquid to solid, and back again.

How birds stay in the air

A bird flaps its wings, glides using air currents and then smoothly descends to perch on a pole. But this is not just any bird, it’s a robot bird. And robots like these could in the next decade be used to respond to emergencies or to hunt down drones posing a threat to safety or security.
