When a beam of light hits your eye, a chain of events is set off that is really quite amazing. Kendall J. Blumer (Washington University School of Medicine) describes a little of it in the Jan. 1 issue of Nature.1 You don’t have to understand the following description; just be glad you don’t have to operate your retina in manual mode:Light streaming into the eye is detected by specialized neurons (photoreceptors) in the retina. In response to light, a coordinated series of molecular events � the so-called phototransduction cascade � is triggered in these cells (Fig. 1). Photons excite pigment-containing proteins called rhodopsins, which then switch on the protein transducin by loading it with the small molecule guanosine triphosphate (GTP). When bound to GTP, transducin turns on a phosphodiesterase, an enzyme that breaks down cyclic guanosine monophosphate (cGMP � another small molecule). High concentrations of cGMP open specialized ion channels in the outer cell membrane. Thus, by reducing the concentration of cGMP, light changes the flow of ions across the membrane of photoreceptive neurons, producing an electrical signal that is necessary for communicating with the brain. (Emphasis added in quotes.)Now that’s just to turn the signal on. When the light stops, it needs to be turned off quickly. Normally, it would take too long for this process to reverse, but the retina has a standard procedure that takes care of it:But this presents a problem. Photoreceptor cells can turn off in less than a second in response to a brief flash of light. In contrast, the hydrolysis of GTP by transducin requires tens of seconds to complete, making it difficult to understand how such a mechanism could account for the rapid turn-off of photoreceptor cells. To get around this problem, photoreceptor cells possess a protein called regulator of G-protein signalling 9 (RGS9) that accelerates transducin’s ability to hydrolyse GTP.Blumer describes what happens when a person has a defect in this accelerator protein. It can take tens of seconds to adjust to a bright room when walking out of a theater. It can take tens of seconds to see when driving into a dark tunnel. And perhaps the worst of all (for Rose Bowl fans): “Moreover, people with this problem also suffer from difficulties in seeing certain moving objects (such as balls thrown during a sporting event).” Having one such accelerator protein would be amazing enough, but now – the rest of the story: “RGS9 is one of nearly 30 such RGS proteins, which regulate signalling by hundreds of receptors coupled to transducin-like G proteins in cell networks of the nervous, cardiovascular, sensory and immune systems.”Kendall J. Blumer, “Vision: the need for speed,” Nature 427, 20 – 21 (01 January 2004); doi:10.1038/427020a.We need to know things like this to avoid taking our bodies for granted. This one deserves a little pondering. Do some simple experiments; see how quickly your eye adjusts to different light levels, and think about all those little protein machines knowing just what to do on cue. Poor Charlie. The eye as he knew it was enough to give him cold shudders. In 1859, biochemistry was not even a science yet. Charlie must be approaching absolute zero by now. A book preceding The Origin of Species by about 2900 years, by a wiser man (Solomon), makes a lot more sense after reading the above description: “The hearing ear and the seeing eye, The LORD has made them both” (Proverbs 20:12).(Visited 13 times, 1 visits today)FacebookTwitterPinterestSave分享0
They follow the sun, but how? Scientists are just finding out the mechanisms behind light tracking in sunflowers.According to New Scientist, the mystery of why some sunflowers track the sun across the sky has been solved. But what a solution! Notice the observations needing to be explained:Growing sunflower plants face the sun at sunrise and point the opposite direction at sunset.During the night, they turn around, ready for the next sunrise.When mature, the flowers stop tracking the sun and just face the sunrise.You can’t trick them to follow a 30-hour cycle with artificial lights. They refuse to move.When artificial lights keep a 24-hour cycle, the sunflowers again move with them.“I’m continually astonished at how sophisticated plants are,” says Stacey Harmer of UC Davis, lead author of experiments. “They’re really masters of coping with the environment.” Sun tracking is called heliotropism. But how do plants know direction without eyes? How do they keep time without clocks?Actually, sunflowers have clocks. All organisms do. In plants, they consist of proteins that interact on a 24-hour cycle in a feedback loop with genes that express them. That’s why a different light cycle doesn’t work. Somehow, they can tell if the artificial day is too long, and they’ll stop moving. You can turn potted plants around, but you can’t fool them. The research is published in Science.How is the light linked to growth? Using markers on the stems, Harmer’s team observed the shaded side of stems growing faster than the sunlit side. Sunlight apparently breaks down growth hormones, causing the stem to bend toward the light. That doesn’t explain, though, how the plant turns back to the east during the night. Gene expression tied to the circadian clock takes care of this in the absence of light cues. PhysOrg says,“The plant anticipates the timing and the direction of dawn, and to me that looks like a reason to have a connection between the clock and the growth pathway,” Harmer said. This behavior of sunflowers had been described by scientists as far back as 1898, but no one had previously thought to associate it with circadian rhythms.It’s astonishing that something everyone has noticed for centuries is just getting explained in 2016. Millions of students have played with plants and light in school for a long time. Observing something, though, is not the same as explaining it. Even so, it doesn’t appear Harmer’s team has it all figured out. They mainly established two things:Here we show that heliotropism in the common sunflower, Helianthus annuus, is generated by the coordinate action of light-signaling pathways and the circadian clock and enhances plant performance in the natural environment.But why does the mature sunflower face east at sunrise and stop tracking the sun all day? The researchers found that east-facing flowers got about five times more pollinators than flowers they turned to face west. Insects seem to like the warm flowers, too, even when they were heated artificially. So it makes sense for the flowers to catch the morning swarm, but why not all day? Two possible reasons were found: one is that the plant reaches its maximum height, so that stems stop growing. Another is that the plant shifts its sensitivity to certain wavelengths of light when mature.The authors summarize their findings:Circadian oscillators enhance fitness by coordinating physiological processes with predictable changes in the environment. Our findings demonstrate that such effects accrue in part through the coordinate regulation of directional growth by environmental response pathways and the circadian oscillator. Such coordination generates the heliotropic movement of young sunflowers, enhancing plant growth, and also leads to the eastward orientation of blooming sunflower disks, promoting a key component of reproductive performance.They credit Charles Darwin with being the first to recognize phototropism. He published a book on The Power of Movement in Plants in 1880. Certainly many a farmer or observant person had noticed the phenomenon long before Darwin did. “Heliotropism, or solar tracking, is a more dynamic form of phototropism, with aerial portions of the plant following the Sun’s movement throughout the day.”Genes, clocks, enzymes — that’s a lot of complexity to regulate this wonder of nature. Sunflowers could do just as well by pointing to the sunrise and staying put. That would be simpler. “Ah,” the Darwinian will say, “but those that follow the sun would be warmer and attract more pollinators.” Look; observing a benefit does not explain how the benefit arrived. How did a blind plant without a brain originate proteins and enzymes that can keep time? How is the circadian rhythm calibrated? How do the enzymes respond to certain wavelengths of light, and not others? Why does the plant follow the sun before the flowers open to be pollinated? Why doesn’t the mature flower track the sun all day to stay warm for pollinators? Heliotropism is costly to the plant. Things don’t just happen; they need to be explained at a detailed level.The simplistic Dar-wine story dulls the senses. It gives a warm feeling of having explained something when it explains nothing. In fact, none of the 3 articles cited here referred to evolution or natural selection at all. Harmer’s team just did good old-fashioned experimentation on the plants. They figured out a few things, but not everything. A simple sunflower is enough to astonish a PhD with its sophistication. That’s the real finding in this story.(Visited 189 times, 1 visits today)FacebookTwitterPinterestSave分享0
3 March 2015The first power has been produced out of the Medupi power station’s Unit 6, South Africa’s energy utility Eskom announced on Monday morning.“Eskom is pleased to announce that first power was produced out of Medupi’s Unit 6 today at 11.03am, making it the first of Medupi power station’s six units to be synchronised,” Eskom said.Synchronisation, or first power, is the process in which the unit’s generator is electrically connected to the national power grid in such a way that its power is aligned with all the other generators to generate and deliver electricity into the national power grid.According to Tshediso Matona, Eskom’s chief executive, this is the final stage marking an exciting milestone towards full commercial power of the plant located in Limpopo.Celebration“Today, we celebrate the achievement with Team Medupi. The electricity flowing into the grid marks a new beginning. Within the next three months, South Africa will see Medupi Unit 6’s full potential of 794MW being fed into the South African national grid. I congratulate Team Medupi, for their efforts in achieving this important milestone for South Africa.”In anticipation of commercial operation, a power station manager has been appointed. The past six years have been spent training and developing a core set of people who will operate the power station’s cutting-edge technology.“Approximately 350 men and women are waiting to join the force of South Africans making history when the unit gets operational,” said Matona. “While Unit 6 is the first of Medupi’s six units, it should be noted that all required auxiliary services for the entire power station are ready to ensure that Medupi’s total output of 4&nbsb;764MW is fully synchronised to the South African power grid.”ContributionPublic Enterprises Minister Lynne Brown said: “The synchronisation of Unit 6 at Medupi Power station is a step towards full-power generation (794MW) and, therefore, a step closer to alleviating some of the energy challenges currently faced by South Africa. This will contribute significantly to South Africa’s and the region’s economy in the long run.“We recognise that this is only the beginning, but I am confident that achieving this significant milestone will sustain the dedication and commitment of the Eskom team as they work towards the completion of the project.”Source: SAnews.gov.za

The fierce battle for gaining the second spot in the Commonwealth Games continued in earnest between India and England on the seventh day of competitions with the hosts edging in front by bagging four gold medals.Teenage archer Deepika Kumari upset an Olympic bronze medallist to win the recurve gold, Harpreet Singh clinched the 25m centre fire pistol gold, archer Rahul Banerjee grabbed the men’s individual recurve gold and world wrestling champion Sushil Kumar won the 66kg title by destroying all his rivals.Vijay Kumar bagged silver behind Harpreet, freestyle wrestler Anuj Kumar also got a silver in men’s 84 kg, trap shooter Manavjit Singh Sandhu secured a bronze while Jayanta Talukdar finished third behind Banerjee.Sania Mirza and Rushmi Chakravarthi beat compatriots Nirupama Sanjeev and Poojashree Venkatesh to secure the women’s doubles bronze in tennis and swell India’s medal kitty.Banerjee’s sister Dola finished third in women’s recurve and grappler Anil Kumar got the bronze in 55kg freestyle as India came up with another impressive display to jump over England and regain the second spot behind leaders Australia.Asian silver medallist Jai Bhagwan (60kg) and nine-time national champion Dilbag Singh assured India of two more boxing medals but defending champion Akhil Kumar made a shock exit in the Commonwealth Games by advancing to the semifinals today.Jai, a Commonwealth Championship gold-medallist, blanked Waheed Sogbamu of Nigeria 10-0, while Dilbag (69 kg) thrashed Botswana’s Moabi Mothiba 11-3 in while Akhil Kumar bowed out after losing to Olympic bronze-medallist Bruno Julie of Mauritius in the 56 kg quarterfinals.advertisementThe two boxers joined Amandeep Singh (49kg) and Suranjoy Singh (52kg), who won their quarterfinal bouts yesterday, in assuring themselves of their maiden CWG medals.The haul of four gold, two silver and five bronze medals took the Indian tally to 28-19-22 while England were once again made to play catch-up with a haul of 25-45-29. Australia were far ahead with 57-33-35.India were also just three gold medals short of overhauling their best-ever harvest of 30 at the Manchester Games in 2002 when three gold medals were awarded for each weight class, a practice that has been discontinued since.The day opened with 17-year-old Ranchi-born Deepika, daughter of an autorickshaw owner, stunning 2004 Athens Olympics bronze medallist Alison James Williamson 6-0, showing amazing precision and steady nerves in windy conditions to win her second gold of the Games.However, it was heartbreak for the 29-year-old Akhil who lost 5-7 to Julie after a see-saw battle.

England are 24/1 at stumps with Andrew Strauss and Ian Bell at the crease in reply to India’s first innings total of 288 – a lead of 67 runs, on Day 2 of the 2nd Test at Trent Bridge in Nottingham on Saturday. Ishant Sharma scalped opener Alastair Cook early. Score | PhotosRahul Dravid scored his 34th Test ton, but it was England, who finished on an advantageous position as Stuart Broad’s hat-trick wiped out India opener’s good work.Starting the day with an overnight score of 24/1 in reply to England’s first innings total of 221, India banking on Dravid’s impressive form frustrated the England bowlers, who could find and answer to the Wall’s patient innings.Dravid got the support he required from left-hander Yuvraj Singh, as the two employed the right-left combination effectively.Earlier in the day, Dravid and VVS Laxman got busy eating into a scanty first innings total that England had posted on Day 1.KP got into a verbal with Laxman after the caught behind review against him went in the batsman’s favour.It was advantage Laxman early in the innings when during James Anderson’s over England’s review got turned down. With that they ended up using both their reviews and that to unsuccessfully.Soon Laxman went on to complete his half-century. But his delight was short lived as England paceman scalped him on 54 with an away moving ball that took an edge of his bat to land in wicketkeeper Matt Prior’s gloves when India’s total was 93.Then it was the turn of the Master Blaster, Sachin Tendulkar, to make an appearance in the middle. And Tendulkar, who is still one short of his 100th international ton, started his innings in style, hitting a four off Bresnan on the fifth ball that he faced during the day.advertisementTendulkar and Dravid were at the crease and India were on 117/2 when lunch was taken on the second day.Minutes into the second session Sachin Tendulkar was seen walking back on a scanty 16 on board. And once again it was Stuart Broad who managed to disappoint Sachin’s fans just like he did during the first innings of the Lord’s Test. An away moving ball was edged by Tendulkar and England captain Andrew Strauss made no mistake in the slips cordon. India lost their third wicket on 119.Rahul Dravid, who has been playing the role of the opener with lan in the absence of regular openers Virender Sehwag and Gautam Gambhir, scored his half-century with precision. Happy Birthday James!However, his partner in the middle Suresh Raina didn’t last long and fell to a James Anderson ball, which would have been better left than played as it was wide outside off. He prodded it and there was virtually no foot movement and Eoin Morgan did the rest at gully. India lost their fourth wicket on 139/4.Post that fall Dravid and Yuvraj Singh batted on at easy as the scanty first innings lead by England gradually got wiped out. At tea, India were 215/4, trailing by six runs.An interesting tweet: Even as the world waits for Sachin’s 100th ton, Dravid continues to pile his tonsIn the third session the went ahead and started to pile up runs to the frustration of the opposition bowlers. Soon the two batsmen reached their respective milestones, Yuvraj Singh scored his half-century while Dravid completed his 34th Test ton. Finally, England managed to get a breakthrough when a Broad’s ball took a faint edge off Yuvraj’s bat and landed in the safe hands of keeper Prior. He fell for 62 as India lost their fifth wicket on 267.This is Stuart Broad’s first hat-trick against IndiaSoon India’s innings hit a sudden low as England paceman Stuart Broad scalped skipper MS Dhoni, Harbhajan Singh and Praveen Kumar on consecutive balls. Post those wickets India were down to 273 for 8.Then it was the turn of centurion Rahul Dravid to take a walk. Dravid was looking to push Tim Bresnan, but the ball took an aerial route and Alastair Cook claimed him at third man. Dravid, who stood in the middle for the whole day, fell after an impressive innings of 117 that was decorated with 15 fours.Unfortunately, India lost four wicket on 273. Soon it was curtains for India as the visitors were all out on 288 – a lead of 67 runs with Broad claimed six wickets.
