If sci-fi adventure films teach us anything, it’s that technology can easily go awry. Jurassic Park is a prime example of that, since the manmade dinosaurs that populated the fictional park in the movie and book ended up going on attack. But that doesn’t stop scientists from giving it a try in real life.

The Northern-Eastern Federal University of Yakutsk has requested $5.9 million to create a facility that would clone recently-unearthed corpses preserved in permafrost. These creatures have been preserved from the Ice Age, making them fascinating to study. However, the facility would create living, breathing clones.

Researchers led by a team from Georgia State University recently announced that they had discovered a molecule that is created by people while they are fasting or on a reduced-calorie diet produces anti-aging effects on the human vascular system -- potentially reducing the severity of ailments that are connected to blood vessels, such as cardiovascular disease.

Dr. Ming-Hui Zou, senior author of the study and director of the Center for Molecular and Translational Medicine at Georgia State, said in a press release, “We found this compound, β-Hydroxybutyrate, can delay vascular aging. That’s actually providing a chemical link between calorie restriction and fasting and the anti-aging effect. It can prevent one type of cell aging called senescence, or cellular aging.”

Boasting more than 3,000 square feet in solar panels, the all-electric SolarImpact yacht is said to be able to cruise without a time limit -- if the weather cooperates and operators aren't in too much of a hurry.

As it is, the yacht's onboard battery can deliver as many as 10 hours of cruising power, with more available when sunshine can be harnessed to replenish the 800-kWh cell. Given a day with abundant sunshine, the panels can collect upwards of 320 kWh.

While the boat's all-electric power systems can push it to a top speed of 22 knots, operators who are willing to cruise along at a little less than a quarter of that speed can circumnavigate the world in about six long as the course doesn't include too many land interruptions.

Although Antarctica is an important part of the planet, playing an essential role in climate change, not nearly enough information is known about it. In fact, one scientist recently pointed out that until recently, we had better maps of Mars than we did of Antarctica.

That has now changed. Working together, a team of researchers at Ohio State University recently created the most detailed map of Antarctica in existence. However, putting together the map, called the Reference Elevation Model of Antarctica (REMA), was a bit of a challenge. The team had to compile all of the information provided by satellites flying over the area, which involved matching high-resolution images up to make sure the layout was captured accurately.

It may be known as the world’s largest hot desert, but the Sahara could soon feature lush vegetation and plenty of rain. It will all be courtesy of solar and wind farms the size of Canada, generating enough energy to actually increase the temperature in the region by 1-2 degrees Celsius. Once natural vegetation is in place, even more cooling will take place, a recent study found.

A team of scientists were able to simulate the effects that 79 terawatts of solar panels would create, combined with 3 terawatts of wind turbines. They found that such a system would increase precipitation by 1.12 millimeters per day, which meant 16 more inches of rain per year. For the driest parts of the Sahara, that’s 16 times more than what those areas normally see.
