Since October 24, 2014, Alan Eustace holds the World Records for vertical speed reached during freefall with a peak velocity of 1,321 kilometres per hour (822 mph) and total freefall distance of 123,414 feet – lasting four minutes and 27 seconds.
“The West Africans are scared” said Ban Ki-moon at a meeting of the United Nations in Washington U.S., discussing the growing threat of Ebola. And you could feel the sense of urgency as World leaders discussed the Ebola crisis. Not enough money has been put forward to tackle the disease. We are late in our response. And the clock is ticking…
Forget about the threat of Ebola for a moment and consider something much closer to home… Meet MRSA – a “superbug”, the bacterium of the decade, the Nemesis of hospitals and operating theatres. A single cell organism that can colonise the living tissues and have a devastating or even fatal impact on the human body. Now. Meet CRISPR – also bacteria. A friend that can potentially help you fight and repel an otherwise deadly bacterial invasion…
It seems quiet at first, and even dull. Not much happening… Dreich, as one might say! Sad. Grim. Bleak. Not much to do… Not much to see here… Just sheep… But wait!! Look closer! Is that Dolly in this field? Now, that’s interesting! Oh, Aye, we’re in Scotland! It changes EVERYTHING…
The human nervous system contains roughly 100 billion nerve cells. Worth pausing for an instant… and read it again. That’s right, 100 billions! To give an idea of the scale, the Milky Way, our own galaxy, contains roughly 100 billion stars. And although human beings are way smaller than galaxies, we begin to appreciate how each one of us is as complex, as mysterious, and as magnificent in its own right, as any large astronomical entity in the physical Universe.
Hydraulic fracturing, more commonly referred to as “fracking” in the media, is the fracturing of rock by a pressurised liquid. Some hydraulic fractures form naturally – certain veins or dikes are examples. However, induced hydraulic fracturing or hydro-fracturing is also a long tried-and-tested mining technique that has been most controversial recently… But let’s not panic!
Earlier this month, UKube-1, a satellite built by Glasgow-based technology firm Clyde Space, successfully launched on a test flight from Baikonur, Kazakhstan. It is the first ever spacecraft to be fully assembled in Scotland.
Geckos are amazing creatures. They scamper up walls, scuttle along ceilings and hang upside down on polished glass surfaces. However, the secret of their amazing climbing ability remained a mystery until relatively recently. The secret lies in weak intermolecular forces, described by Van der Waals in 1873.
What is the difference between heat and temperature? Heat is thermal energy. Temperature is a measurement of the average kinetic energy of the particles which compose the matter being tested. When heat flows into a material, one of two things happen: either the temperature of the material can rise, or there may be a change in its state (such as from ice to liquid, or liquid to vapour).
