Reisner Laboratory in Cambridge developed their platform to achieve unassisted solar-driven water-splitting for more efficient absorption of solar light than natural photosynthes.
A new study, led by academics at St John’s College has used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies.

"I scienced that"
Hmmm...gonna have to disagree with you there. Science is a noun.

Microbubble contrast agents: a new era in ultrasound
"Contrast agents are widely used in imaging, but until recently they had little place in ultrasonography. This has changed with the introduction of microbubbles—small (typically 3 μm in diameter) gas filled bubbles that are usually injected intravenously. Injecting a gas into the circulation may seem potentially hazardous, but extensive clinical experience has shown that the tiny volume of air or gas given (under 200 μl) is not dangerous, and the safety of microbubbles compares well to that of conventional agents in radiography and magnetic resonance imaging.1 Although microbubbles were originally designed simply to improve conventional ultrasound scanning, recent discoveries have opened up powerful emerging applications. This article describes some of these applications in radiology and cardiology and discusses the potential of microbubbles for therapy."

From the book Biocentrism by Robert Lanza
In reality, recent experiments show conclusively that the brain’s electrochemical connections, its neural impulses traveling at 240 miles per hour, cause decisions to be made faster than we are even aware of them. In other words, the brain and mind, too, operate all by itself, without any need for external meddling by our thoughts, which also incidentally occur by themselves. So control, too, is largely an illusion. As Einstein put it, “We can will ourselves to act, but we cannot will ourselves to will.”
The most cited experiment in this field was conducted a quarter-century ago. Researcher Benjamin Libet asked subjects to choose a random moment to perform a hand motion while hooked up to an electroencephalograph (EEG) monitor in which the so-called “readiness potential” of the brain was being monitored. Naturally, electrical signals always precede actual physical actions, but Libet wanted to know whether they also preceded a subject’s subjective feeling of intention to act. In short, is there some subjective “self ” who consciously decides things, thereby setting in motion the brain’s electrical activities that ultimately lead to the action? Or is it the other way ’round? Subjects were therefore asked to note the position of a clock’s second hand when they first felt the initial intention to move their hand.
Libet’s findings were consistent, and perhaps not surprising: unconscious, unfelt, brain electrical activity occurred a full half second before there was any conscious sense of decision-making by the subject. More recent experiments by Libet, announced in 2008, analyzing separate, higher-order brain functions, have allowed his research team to predict up to ten seconds in advance which hand a subject is about to decide to raise. Ten seconds is nearly an eternity when it comes to cognitive decisions, and yet a person’s eventual decision could be seen on brain scans that long before the subject was even remotely aware of having made any decision. This and other experiments prove that the brain makes its own decisions on a subconscious level, and people only later feel that “they” have performed a conscious decision. It means that we go through life thinking that, unlike the blessedly autonomous operations of the heart and kidneys, a lever-pulling “me” is in charge of the brain’s workings. Libet concluded that the sense of personal free will arises solely from a habitual retrospective perspective of the ongoing flow of brain events.

MIT Physicists Describe a Theoretical Fifth Loko
CAMBRIDGE, Mass. — Scientists at the Massachusetts Institute of Technology’s Department of Physics announced today the theoretical discovery of the fifth sequence of the energy/alcohol drink Four Loko, belligerent physicists slurred at a press conference.
“No... listen. No, you listen! I think... I think we found the Fifth Loko, and... just fucking hear me out, man — it’s fucking nuts,” mumbled a visibly intoxicated and amped-up Dr. Sandra Weymouth, lead professor on the project. “You know, we all know the first Four Lokos are caffeine, guarana, taurine, and... shit. Caffeine, guarana... taurine. Alcohol? I think so. Those cowards took out the good stuff, but we figured it out, and we found a fifth. Boo-yah, bitches.”

“The most fundamental aspect of the universe... is information. Information can be equated with thought or mind or mental constructs independent of any material everyday conception.... The universe of mass and energy and forces, as we experience it on an everyday practical level, may have had its origin in a thought that inserted information into an otherwise blank (data free) holographic system.... Inserting more thoughts, more information, expands and changes the system...”5
