The Future Of Bulb-Changing.

In addressing the question of who invented the incandescent lamp, historians Robert Friedel and Paul Israel list 22 inventors of incandescent lamps prior to Joseph Swan and Thomas Edison. They conclude that Edison's version was able to outstrip the others because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve (by use of the Sprengel pump) and a high resistance that made power distribution from a centralized source economically viable

Historian Thomas Hughes has attributed Edison's success to his development of an entire, integrated system of electric lighting

The universe is expanding at an accelerating rate – or is it? | University of Oxford

'Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace.

Their conclusions were based on analysis of Type Ia supernovae – the spectacular thermonuclear explosions of dying stars – picked up by the Hubble space telescope and large ground-based telescopes. It led to the widespread acceptance of the idea that the universe is dominated by a mysterious substance named 'dark energy' that drives this accelerating expansion.

Now, a team of scientists led by Professor Subir Sarkar of Oxford University's Department of Physics has cast doubt on this standard cosmological concept. Making use of a vastly increased data set – a catalogue of 740 Type Ia supernovae, more than ten times the original sample size – the researchers have found that the evidence for acceleration may be flimsier than previously thought, with the data being consistent with a constant rate of expansion.'

Marginal evidence for cosmic acceleration from Type Ia supernovae : Scientific Reports

'... Abstract

The ‘standard’ model of cosmology is founded on the basis that the expansion rate of the universe is accelerating at present — as was inferred originally from the Hubble diagram of Type Ia supernovae. There exists now a much bigger database of supernovae so we can perform rigorous statistical tests to check whether these ‘standardisable candles’ indeed indicate cosmic acceleration. Taking account of the empirical procedure by which corrections are made to their absolute magnitudes to allow for the varying shape of the light curve and extinction by dust, we find, rather surprisingly, that the data are still quite consistent with a constant rate of expansion.

God treats everyone alike. He accepts people only because they have faith in Jesus Christ. All of us have sinned and fallen short of God's glory. But God treats us much better than we deserve, and because of Christ Jesus, he freely accepts us and sets us free from our sins.

God's Spirit makes us loving, happy, peaceful, patient, kind, good, faithful, gentle, and self-controlled. There is no law against behaving in any of these ways.

And because we belong to Christ Jesus, we have killed our selfish feelings and desires. God's Spirit has given us life, and so we should follow the Spirit. But don't be conceited or make others jealous by claiming to be better than they are.

Study: At molecular level, evolutionary change is unpredictable | Nebraska Today | University of Nebraska–Lincoln

'Biologists have been contemplating evolutionary change since Charles Darwin first explained it.
Using modern molecular tools and fieldwork, University of Nebraska-Lincoln biologist Jay Storz and colleagues have demonstrated for the first time that different species can take different genetic paths to develop the same trait. The team’s findings appear in the Oct. 21 issue of the journal Science.


To find that out, Storz turned to birds living in South America’s Andes Mountains. Comparing high-altitude bird species with their lowland counterparts, his team determined that the high-altitude birds had evolved red blood cells with hemoglobin proteins that more readily bind oxygen molecules. This trait benefits species living in low-oxygen settings, such as the mountains.

Storz and his team tested the hemoglobin proteins from numerous high-altitude bird species and identified which differences, or mutations, in the proteins’ makeup were responsible for the high-altitude trait. In most cases, the change in protein function among the different species was caused by different mutations.

“What this indicates is that there are many possible mutations that can all produce the same phenotypic effect (trait),” Storz said. “We can’t predict which particular mutations are responsible for these changes.” One possible reason for this variability is that during evolution, the hemoglobins of different species have each accumulated their own unique set of mutations. Given these distinct genetic backgrounds, a mutation that produces a beneficial effect in one species may produce a detrimental effect in a different species.'

Saturn's mysterious hexagon has changed from blue to gold - and no one knows why - ScienceAlert

'It’s like nothing we’ve seen on any other planet in the entire Universe, and now the mysterious structure on Saturn’s north pole just got even weirder.

In just four years, Saturn’s hexagon has changed its colour from blue to gold. So far, our best guess as to why this change occurred is that this is what it looks like when Saturn's north pole gears up for next year's summer solstice.'

Catalog Page for PIA21049

'... Scientists are investigating potential causes for the change in color of the region inside the north-polar hexagon on Saturn. The color change is thought to be an effect of Saturn's seasons. In particular, the change from a bluish color to a more golden hue may be due to the increased production of photochemical hazes in the atmosphere as the north pole approaches summer solstice in May 2017.

Researchers think the hexagon, which is a six-sided jetstream, might act as a barrier that prevents haze particles produced outside it from entering. During the polar winter night between November 1995 and August 2009, Saturn's north polar atmosphere became clear of aerosols produced by photochemical reactions -- reactions involving sunlight and the atmosphere. Since the planet experienced equinox in August 2009, the polar atmosphere has been basking in continuous sunshine, and aerosols are being produced inside of the hexagon, around the north pole, making the polar atmosphere appear hazy today.

Other effects, including changes in atmospheric circulation, could also be playing a role. Scientists think seasonally shifting patterns of solar heating probably influence the winds in the polar regions.

BIG & Hyperloop One release video sneak peek of Hyperloop designed to connect Abu Dhabi & Dubai | Inhabitat - Green Design, Innovation, Architecture, Green Building

'Danish architecture firm Bjarke Ingels Group (BIG) has released a teaser video showing off its design of a Hyperloop project that promises to link Abu Dhabi and Dubai. The ultra high-speed capsule transport aims to turn the 93-mile trip between the two busy cities into a minutes-long commute, offering an efficient means of moving both people and cargo. Jakob Lange, a partner and head of BIG Ideas (the design firm’s tech division), leads the video sneak peek ahead of the Hyperloop design’s November 7 unveiling.'
