Silk spun by graphene-fed spiders is one of the strongest materials on Earth

Scientists have found a way to increase the overall strength and durability of spider silk. After feeding a spider a small amount of graphene and carbon nanotubes, the creature produced webs that were five times stronger than normal.

Spider webs are already strong enough to restrain small insects unlucky enough to fly into them, and soon, they may be capable of carrying the weight of a person.

In a new study published in 2D Materials, Nicola Pugno at the University of Trento in Italy and his team detail how they cranked arachnids’ already impressive metabolic process up to 11 by adding graphene and carbon nanotubes to a spider’s drinking water.

Afterward, the spider produced silk as it normally would, but the silk was five times stronger, putting it on par with the likes of pure carbon fibers and Kevlar — the strongest materials on Earth.

OH MY GOD whyyyy did no one tell me you’re supposed to send thank-yous after interviews?? Why would I do that???

“Thank you for this incredibly stressful 30 minutes that I have had to re-structure my entire day around and which will give me anxiety poos for the next 24 hours.”

I HATE ETIQUETTE IT’S THE MOST IMPOSSIBLE THING FOR ME TO LEARN WITHOUT SOMEONE DIRECTLY TELLING ME THIS SHIT

What are the four fundamental forces of nature?

In physics, the fundamental interactions, also known as fundamental forces, are the interactions that do not appear to be reducible to more basic interactions. There are four conventionally accepted fundamental interactions—gravitational, electromagnetic, strong, and weak. Each one is described mathematically as a field. The gravitational force is attributed to the curvature of spacetime, described by Einstein’s general theory of relativity. The other three, part of the Standard Model of particle physics, are described as discrete quantum fields, and their interactions are each carried by a quantum, an elementary particle.

Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including planets, stars and galaxies, and other physical objects. Since energy and mass are equivalent, all forms of energy (including light) cause gravitation and are under the influence of it. On Earth, gravity gives weight to physical objects, and causes the ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing, forming stars – and for the stars to group together into galaxies – so gravity is responsible for many of the large scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects.

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. 

Electromagnetic phenomena are defined in terms of the electromagnetic force, sometimes called the Lorentz force, which includes both electricity and magnetism as different manifestations of the same phenomenon.

Ordinary matter takes its form as a result of intermolecular forces between individual atoms and molecules in matter, and is a manifestation of the electromagnetic force. Electrons are bound by the electromagnetic force to atomic nuclei, and their orbital shapes and their influence on nearby atoms with their electrons is described by quantum mechanics. The electromagnetic force governs the processes involved in chemistry, which arise from interactions between the electrons of neighboring atoms.

The strong interaction is the mechanism responsible for the strong nuclear force (also called the strong force or nuclear strong force). At the range of 10−15 m (1 femtometer), the strong force is approximately 137 times as strong as electromagnetism, a million times as strong as the weak interaction and 1038 times as strong as gravitation. The strong nuclear force holds most ordinary matter together because it confines quarks into hadron particles such as the proton and neutron. In addition, the strong force binds neutrons and protons to create atomic nuclei. Most of the mass of a common proton or neutron is the result of the strong force field energy; the individual quarks provide only about 1% of the mass of a proton.

The weak interaction (the weak force or weak nuclear force) is the mechanism of interaction between sub-atomic particles that causes radioactive decay and thus plays an essential role in nuclear fission. 

The weak force, or weak interaction, is stronger than gravity, but it is only effective at very short distances. It acts on the subatomic level and plays a crucial role in powering stars and creating elements.

The world’s most detailed scan of the brain’s internal wiring has been produced by scientists at Cardiff University.

Not only does the scan show the direction of the messaging, but also the density of the brain’s wiring. Conventional scans clearly show lesions - areas of damage - in the brain of MS patients.But this advanced scan, showing axonal density, can help explain how the lesions affect motor and cognitive pathways - which can trigger movement problems and extreme fatigue.

Prof Derek Jones, CUBRIC’s director, said it was like getting hold of the Hubble telescope when you’ve been using binoculars. “The promise for researchers is that we can start to look at structure and function together for the first time,” he said.

sure he’s well versed in leftist theory but does he do the dishes

Yes I’m reposting… but this is my absolute favorite post. Great way to start to my intense day, full of cramming and memorizing pages and pages of lab procedures. 

hey reblog this if you think girls can study and excel in computer science
