In what the authors are hailing as a “game - changer” in the realm of weight loss therapy, a major global study has demonstrated how an obesity drug can cut significant body weight from many of those who take it. Originally developed to treat diabetes, the drug in question works by taking control of the body’s appetite regulation system, with one third of the study recipients cutting more than one fifth of their body weight through weekly injections combined with conventional weight - loss programs.

Owing to the many different ways atoms can be arranged within the material, ice can exist in many more forms than what’s known as ice I, the type we’re all familiar with. Scientists have actually categorized 18 different types of the material, each with its own unique crystalline structure, and now have added another, called ice XIX, to the list.

To the envy of us humans, limb regeneration is common to certain groups of animals. But while it’s normally a leg here or a tail there, scientists have now discovered one of the most extreme examples ever found – sea slugs that voluntarily detach their own heads and then regrow an entire body from it.

A quantum internet would be much faster and more secure than the one you’re using right this second – and now such a network may be one step closer to reality. Scientists have used quantum teleportation to send information over long distances, with a higher fidelity than ever before.

Through experimentation with a newly created type of material, scientists in Russia have landed on a battery design with a number of promising performance benefits, in particular an ability to offer triple the capacity of today's solutions. The breakthrough comes from replacing the material used for one of the battery's electrodes with hollowed out nanospheres that enable the device to not only hold more charge, but remain stable over an impressive period of time.

Taking inspiration from the way sea cucumbers can strengthen their exterior when in danger, scientists in Germany have developed a novel wafer-thin paper material that can transition from firm to soft via an electrical switch. The researchers envisage a number of uses for their creation, including adaptive damping materials that harden when subjected to heavy loads.

Judging how ripe a piece of fruit is can be a frustrating process for everyone from farmers to shoppers. Now, researchers at Shibaura Institute of Technology (SIT) in Japan have developed a new high-tech way to check, without touching or damaging soft fruit like mangoes. All it takes is a laser and some plasma shockwaves.
