How To Win Your Physics Class Egg Drop Competition

The problem is simple enough. You’ve got a raw egg, and it’s going to be dropped from a high place. You have to build a contraption so that it doesn’t break when it hits. Easy? Maybe. But how do you make it as light as possible? Or as small as possible?


US Air Force Certifies SpaceX For Military Space Missions

The US Air Force has announced that SpaceX is now certified to launch military and spy satellites. That means that the United Launch Alliance, a joint effort between Boeing and Lockheed Martin, no longer holds the monopoly on national security space missions.


Giraffes And The 'Necks For Sex' Hypothesis

Sexual selection doesn’t necessarily just shape sexual anatomy — it can have as profound an effect on the rest of an animal’s body as natural selection does. In both cases, the end result is more babies for animals that look or act a particular way.


US Air Force Can Use An Electromagnetic Pulse To Kill Enemy Computers

One of the US Air Force’s most high-tech weapons is a tool that can’t hurt people — but it kills electronic devices.


Male Butterflies Ejaculate, Female Butterflies Digest

A mating system that puts the sexes in conflict can evolve some pretty extreme copulatory structures. Spiky penises and twisty vaginas are the tip of the iceberg. According to a study in the Journal of Experimental Biology last week, we should add protein-melting vaginal tracts to the list.


Exoplanet Hunters Will Comb Starlight With Lasers

This picture shows the spectrum of light. You may have seen similar images in the past, but this one is something special — because it’s made of star light.


The New Global Strategy To Counter Drug-Resistant Microbes

The World Health Organisation has a new strategy for fighting drug-resistant diseases like MRSA and multidrug-resistant tuberculosis, which cost lives and strain healthcare systems around the world.


Robotic Cockroaches Are Perfect Tiny Aircraft Carriers For Robotic Birds

Humanity wouldn’t be where it is today if we didn’t learn how to work together, but robots have once again demonstrated that they’re much faster at adapting than us because a robotic cockroach is now helping a robotic bird take flight without the need for a human to launch it.


This Is The First Single-Molecule Diode That Could Actually Be Useful

The diode is a very simple-sounding little electronic device: it allows current to flow easily in one direction, but not the other. But while the quest to miniaturise them to the molecular scale has worked in the past, only now is it a truly practical proposition.


How Scientists Plan To Hack Your Nervous System

One nerve connects your vital organs, sensing and shaping your health. If we learn to control it, the future of medicine will be electric.
