Star Trek Shields For Tanks

by Mark E. Lasbury in The 'Scope

Star Trek deflectors absorbed or deflected energy beams, but would they work against bullets or asteroids? Scientists are on working on armors and plasma systems that can stop projectiles. In some cases we use explosions to stop explosions. In others, tanks are turned into electrical pulse generators that zap incoming rockets. But the most amazing is the wall of exploding plasma that will be the first true defensive energy shield.... Read more »

Shields Up! Lay In A Course For Mars

by Mark E. Lasbury in The 'Scope

Deflector shields allowed Star Trek and other sci-fi franchises to have long space battles. Without them, one good strike and everyone was dead – that wouldn’t lend itself to sequels.

We don’t need shields for space battles yet, but we do need them to get to Mars. Cosmic radiation will kill or injure every astronaut unless we can deflect the radiation away from the spacecraft. We’re just about to build real deflectors, and our teachers are the magnetic fields we find ........ Read more »

I See, Said The Blind Man

by Mark E. Lasbury in The 'Scope

I can’t stand it when I get dust in my eye. Can you imagine having a neural implant in your eye? Star Trek’s Geordi LaForge had implanted electrodes that, along with his visor, let him see. Visual neural prostheses are no longer a thing of science fiction, making the blind see is science fact. The only difference is that he saw in all wavelengths of the electromagnetic spectrum. But there’s no reason we can’t do that as well. ... Read more »

How photosynthesis is inspiring solar power research

by GrrlScientist in Maniraptora

SUMMARY: To meet humanity’s growing energy demands, scientists are taking lessons from plants, which perfected the process of capturing the sun’s rays and transforming that into starch. Might scientists be able to adapt the photosynthetic process pioneered by plants and adapt it to meet human demands? ... Read more »

Pulling Us Toward Tractor Beams

by Mark E. Lasbury in The 'Scope

Tractor beams pulling space ships are things of science fiction, but tractor beams pulling small objects on Earth are science fact. Beams usually push things away with their force, but we have learned to manipulate them so that they push things back to the source – we can do it with water, sound and even laser light....

Star Trek Phasers, Coming To Us Sooner or Laser

by Mark E. Lasbury in The 'Scope

Can we make a Star Trek phaser? In a classic example of life imitating art, the militaries of many countries are actively pursuing such directed energy weapons. So far, we’ve developed high-energy lasers and masers, particle beams, and something that looks a lot like an aimed lightning bolt. But our versions are huge, what must be overcome to make hand-held versions?... Read more »

I'll Beam Right Over

by Mark E. Lasbury in The 'Scope

Star Trek’s 50th anniversary is next year. Wouldn’t transporting a person to the ISS be a great way to celebrate? Well, there are a couple of problems to overcome, but we’re on our way. We have recently learned how to transport information and light from one place to another, without it ever existing anywhere in between! And this will help us make quantum computers that will be able to transport all the information contained in every atom of your body.... Read more »

Sometimes Warped Thinking Is A Good Thing

by Mark E. Lasbury in The 'Scope

As Star Trek’s 50th anniversary approaches, are we getting closer to traveling at light speed? Believe it or not – yes, we are. We have begun to understand and harness the power of antimatter, and the plasma bubble-driven warp drive has moved from silly idea to serious consideration – so much so that NASA has designed a warp drive ship, the IXS Enterprise, of course....

Star Date: Pretty Darn Soon

by Mark E. Lasbury in The 'Scope

Star Trek celebrates its 50th anniversary in 2016. In preparation for the celebrations, we’re checking in on how close we are to making Star Trek technology a reality. The replicator made food and recycled trash, and later was used to make parts for the Enterprise. A machine fabricated what they needed on the spot. We have that now on the space station! Do you know how 3-D printing works and how we print parts, food, and even living tissue? Here’s how.... Read more »
