Cancer is one of humanity’s biggest killers, but scientists are coming up with some creative ways to fight back. Researchers at the University at Buffalo have developed new kinds of nanoparticles that can infiltrate, heat up and kill cancer cells more effectively and efficiently than similar methods.

Using nanoparticles to fight cancer has become a growing area of research in recent years. The general concept is to get the particles into tumors, before activating them with radiation to trigger a reaction that destroys the cancer cells without harming healthy tissue. What kind of nanoparticle and radiation are used can vary, as can the type of reaction that’s triggered.

Previous work has killed tumors by activating CeF3 nanoparticles with X-rays to create toxic singlet oxygen, used infrared light to ramp up cancer’s pH balance, used laser pulses to heat up gold nanoparticles, or a combination of several of these.

Humans aren’t the only ones who have harnessed the power of electricity. Some bacteria do this, too, by producing structures that extend from their surface like wires to transfer electrons over distances. Now, scientists at NASA’s Ames Research Center in California’s Silicon Valley are exploring this phenomenon to see if they can make use of these special microbes to perform essential functions on future space missions — from generating electricity to treating wastewater or producing medicines. With an experiment launching to the International Space Station, researchers will see whether the microbes work the same in space as they do on Earth.

To appreciate the rare abilities of the bacterium in question, called Shewanella oneidensis MR-1, you have to know what moving electrons around has to do with life. The transfer of electrons from one molecule to another is essential to all organisms, because it allows for the production of energy they need to survive. One reason that humans depend on oxygen is that this energy-producing chain reaction inside our cells is powered by transferring electrons to molecules of oxygen. The same goes for anything else that breathes oxygen, including Shewanella. But what makes this microorganism special is that it also has a back-up system that kicks in when the environment is low on oxygen. Shewanella keeps calm and carries on producing energy by using metals, like iron and manganese, instead.

India’s space program wants to go where no nation has gone before -– to the south side of the moon. And once it gets there, it will study the potential for mining a source of waste-free nuclear energy that could be worth trillions of dollars.

ELON MUSK wants to plump humans on Mars by 2024 and the first batch of settlers could live in 3D-printed home pods that pack hologram computers.

You’ll be able to tour the Red Planet habitat in virtual reality and view a scale model of the sci-fi living space at the Goodwood Festival of Speed next month.

Ever wish you could visit other planets in our solar system without launching on a deep-space mission? Now you can embark on an interplanetary adventure right from the palm of your hand, thanks to gorgeous, 3D-printed planet models and an augmented-reality (AR) app.

Brought to you by AstroReality, the same company that created the “Lunar” AR moon model and its new Earth counterpart, this set includes miniature models of all eight planets and one model of the dwarf planet Pluto. Each model is 1.2 inches (3 centimeters) in diameter and color-printed with a resolution of 0.1 millimeter per pixel.

Friday morning at 5:24 am (0924 GMT), a rocket owned by the US company SpaceX will blast off from Florida carrying two and a half tons of gear from NASA, only to dock three days later and 250 miles (400 kilometers) above Earth at the International Space Station.

The rocket itself is not new. It launched a NASA satellite into orbit two months ago, then landed back on Earth—upright—on a barge in the Atlantic Ocean off Cape Canaveral.

Even the Dragon capsule, carrying the cargo and affixed to the top of the rocket was used before, having flown a mission to the ISS in 2016.
