Humboldt State softball returns home, sweeps doubleheader against Dominguez Hills

first_imgMcKinleyville >> With a Cal State Dominguez Hills team and its California Collegiate Athletic Association-worst ERA rolling into town, there was plenty of potential for the potent Humboldt State offense to do some serious damage.That was certainly the case in the Jacks’ first game back within Humboldt County lines.Led by senior Breonna Bejaran’s two-home run day, the No. 1-nationally ranked Jacks exploded for 15 hits as the top of the Humboldt order did major damage from the first inning …last_img

It’s a Long (Roundabout) Way from Amphioxus

first_img“Every solution breeds new problems” laments a Murphyism, and Henry Gee feels the pain.  In Nature this week,1 he delved into the growing quandary about where to put the common ancestor of starfish, sea squirts and chordates, including the vertebrates and us human beings.  His challenge is to prove the idiot’s sanity:So, if lancelets really are close relatives of echinoderms, what are the implications for our picture of deuterostome evolution?  The short answer is that the textbook scheme is turned on its head.  Rather than the steady acquisition of progressively more chordate-like (and, by implication, human-like) features from an ancestor with nothing much to recommend it, the story becomes one of persistent loss.  The last common ancestor of extant deuterostomes would have been a free-living, bilaterally symmetrical creature with a distinct throat region perforated by gill slits, segmented body-wall musculature and possibly a reasonably sophisticated brain and central nervous system.  In a sentence, the ancestor would have looked like a cross between an amphioxus and a larger, brainier, tunicate tadpole larva.  Crazy? Possibly. But possibly not. (Emphasis added in all quotes.)Reporting on phylogenetic study by Delsuc et al. from fossils and genetics in the same issue,2 the senior editor at Nature tried to be upbeat about the latest proposal, but called it another exercise in humility.  “Time and again,” he preached, “further work has exposed our prejudices for the parochial conceits that they are.” A quote from the paper by Delsuc et al. shares this view, and demonstrates the revolutionary nature of the proposed new phylogeny:The monophyly of Olfactores invalidates the traditional textbook representation of chordate, and even deuterostome, evolution as a steady increase towards complexity culminating in the highly specialized brain of vertebrates.  This anthropocentric interpretation is perhaps best reflected by the terms ‘Euchordata’ (that is, ‘true chordates’) or ‘chordates with a brain’, which are used to designate the grouping of cephalochordates and vertebrates.  Tunicates should therefore no longer be considered as ‘primitive’ but rather as derived chordates with highly specialized lifestyles and developmental modes.    Meanwhile, over in Science Now, Elizabeth Pennisi quoted some other evolutionists not quite ready to accept the new phylogenetic tree.  Calling the tunicate an “ugly sister,” Pennisi quoted experts saying the proposal will turn some heads, and the jury is still out.  She said they said, “Tunicates and larvaceans evolve rapidly and have gained and lost so many genes that it’s very hard to position them properly in an evolutionary tree.”1Henry Gee, “Evolution: Careful with that amphioxus,” Nature 439, 923-924 (23 February 2006) | doi:10.1038/439923a.2Delsuc et al., “Tunicates and not cephalochordates are the closest living relatives of vertebrates,” Nature 439, 965-968 (23 February 2006) | doi:10.1038/nature04336.Evolutionists could use a lot more humility.  They should quit the parochial school of Pope Charlie that is producing a class of lemmings who cling to crazy ideas.  What Gee is saying contradicts evolution.  This new story line puts the advanced muscles, nervous system and mobility of Amphioxus before organisms that were assumed more primitive (in the old “progressive” evolution picture), and describes subsequent evolution as a story of persistent loss.    Meanwhile, Eugenie Scott and Alan Gishlick sit on a Grand Canyon beach trying to whoop up enthusiasm for their evening song service: “It’s a long way from amphioxus / It’s a long way to us. / It’s a long way from amphioxus to the meanest human cuss. / Goodbye fins and gill slits / Hello lungs and hair! / It’s a long, long way from amphioxus, / But we come from there” (10/06/2005 commentary).  It’s even longer when you’re going backwards.  Gee’s story gives them more food for cuss.(Visited 17 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Inner Ear Hair Cells Overcome Friction

first_img The human ear has an extraordinarily large sensitivity range of a trillion to one, allowing us to hear a rocket launch or the footfalls of a cat on a carpet.  According to Werner Gitt, the ear is our highest-precision sense organ, capable of responding over twelve orders of magnitude without switching (The Wonder of Man, p.21).  Some of this sensitivity is amplified by the eardrum and middle ear ossicles, but the paper reported above shows even more fine-tuning inside the cochlea.  Gitt’s book is highly recommended for generating a profound feeling of awe over the design of our senses.  Proverbs said, “The seeing eye, and the hearing ear, the Lord has made them both” (Prov. 20:12).(Visited 48 times, 1 visits today)FacebookTwitterPinterestSave分享0 The cochlea, that spiral-shaped structure in the inner ear, is filled with fluid.  In this fluid, tiny hair cells called stereocilia are positioned in bundles along the length of the structure.  These bundles sense vibrations transmitted into the fluid from the bony levers of the inner ear.  The vibrations picked up by the hair cell bundles, each tuned to its own frequency, mechanically transduce the sound impulses by opening ion channels that set up electrical impulses in the auditory nerve, that travel to the brain.  But motion in fluid creates friction known as viscous drag.  How do the hair cell bundles overcome it?  Scientists have figured out that the hair cells in the bundles are not only finely tuned to reduce viscous drag, but actually to employ it for even higher sensitivity to sound. Publishing in Nature,1 scientists from Howard Hughes Medical Institute, with help from European academies, explained the problem of viscous drag, and two ways the ear deals with it: The detection of sound begins when energy derived from an acoustic stimulus deflects the hair bundles on top of hair cells.  As hair bundles move, the viscous friction between stereocilia and the surrounding liquid poses a fundamental physical challenge to the ear’s high sensitivity and sharp frequency selectivity. Part of the solution to this problem lies in the active process that uses energy for frequency-selective sound amplification.  Here we demonstrate that a complementary part of the solution involves the fluid-structure interaction between the liquid within the hair bundle and the stereocilia. What they found is that the positioning of the individual stereocilia causes them to move in concert, so that viscous drag within the bundle is dramatically reduced: “We find that the close apposition of stereocilia effectively immobilizes the liquid between them, which reduces the drag and suppresses the relative squeezing but not the sliding mode of stereociliary motion.”  They can thus slide as the bundle bends without stirring up the liquid.  Further, “The obliquely oriented tip links couple the mechanotransduction channels to this least dissipative coherent mode, whereas the elastic horizontal top connectors that stabilize the structure further reduce the drag.”  The relative motion is reduced to just a fraction of a billionth of a meter (nanometer). Their opening paragraph provides a picturesque view of the workings of this remarkable organ: A hair bundle is a microscopic array of quasi-rigid, cylindrical stereocilia separated by small gaps filled with viscous endolymph. Like an array of organ pipes, the stereocilia vary monotonically in length across the hair bundle…. The tip of each short stereocilium is attached to the side of the longest adjacent stereocilium by a tip link, the tension in which controls the opening and closing of transduction channels. Adjacent stereocilia are also interconnected along all three hexagonal axes by horizontal top connectors. At the tall edge of the bundle in many species stands a single kinocilium, the process to which mechanical stimuli are applied and that is ligated to the adjacent stereocilia by kinociliary links. Why are the stereocilia arranged in bundles?  “The small difference between the drag coefficients for a single stereocilium and for an entire hair bundle reveals the striking advantage that grouping stereocilia in a tightly packed array offers to the auditory system.”  Using models from a bullfrog inner ear magnified 12,000 times and various mathematical techniques, they were able to measure the viscous drag of the coherently-arranged stereocilia.  Their conclusion explains how the findings contribute to understanding the remarkable sensitivity of the ear: In conclusion, because all stereocilia and the liquid between them move in unison over the whole auditory spectrum, with the relative motions apparent only on a sub-nanometre scale, most stereocilia inside the hair bundle are shielded from the external liquid and experience little viscous drag. Although viscous forces might be thought to impair sensitivity and frequency selectivity, the hair bundle’s structure actually minimizes energy dissipation, making it easier for the active process to keep the ear tuned. The tight clustering of stereocilia even transforms liquid viscosity into an asset by using it as a simple means of activating numerous mechanosensitive ion channels in concert. The authors made no attempt to explain how this arrangement might have evolved.  1.

South Africa, Turkey pact to boost trade

first_img17 February 2012 A declaration signed on Thursday between South Africa and Turkey will see the two countries boost relations in areas including infrastructure development, mining and energy, says the Department of Trade and Industry (DTI). At the end of the second session of the Turkey-South Africa Joint Economic Commission meeting in Ankara on Thursday, the two countries recommitted themselves to further enhance trade and economic relations. The Joint Economic Commission (JEC) promotes trade, investment and economic co-operation between the two countries. Turkish Minister of Energy and National Resources Taner Yildiz and South African Trade and Industry Minister Rob Davies, who co-chaired the JEC, signed the declaration on behalf of the two countries on Thursday.Deepening economic relations Infrastructure development, small, medium and micro enterprise (SMME) development, special economic zones, mining and energy, jewellery making and agriculture are some of the areas in which the declaration seeks to develop cooperation. The work around the designated areas of cooperation will go a long way towards deepening economic relations between Turkey and South Africa. “For example, cooperation in infrastructure development could help to make the logistic system in South Africa more efficient and contribute positively to job creation,” the DTI said in a statement. “Similarly, it is expected that cooperation in SMME development would lead to positive job creating outcomes.” Davies said the signing of the declaration coincided with Turkey’s search for expanding its trade relations with the African continent. This search, he said, was not misguided, as the International Monetary Fund projected over 5% economic growth for the continent. Source: BuaNewslast_img read more

Young South Africans plan to stay at home

first_imgThe youth are our future, and in South Africa, that future wants to stay at home. Less than 10% of South Africans under the age of 24 planned to migrate to another country, a Brand South Africa survey has found. The majority of South Africans interviewed in a recent survey are hopeful and committed about their future in the country. (Image: Brand South Africa)• Mandela Day aiming for 160 countries • Royal boost for conservation in Africa • People and complexity: the missing ingredients in celebrity activism for Africa • Brilliant young minds at the CSIR • People show positive image of Africa Melissa JavanThe majority of young people in South Africa want to continue living in the country and have no intention of leaving, despite the socio-economic challenges they face, according to a recent survey undertaken by Brand South Africa.The Domestic Perceptions Research survey looked at the optimism of the youth. It was conducted over four weeks, from 17 November to 12 December 2014, and interviews were done with 2 524 people between the ages of 15 and 55. The interviews were conducted nationally, in the individuals’ homes.It found that the South African population is young, with most people between the ages of 15 and 34. This was in line with the Census results, which found that 66% of the country’s population was under the age of 34.According to the Domestic Perceptions Research, South Africa’s youth are committed, proud, hopeful and aspirational about the country.Leigh-Gail Petersen, a researcher at Brand South Africa, said these results indicated that the youth were optimistic about their future in the country. “That future can only be realised through constructive engagement,” she added.The majority of people between the ages of 15 and 55 said they would continue to live and work in South Africa regardless of the social, economic and political situation in the country.A total of 85% of those 55 years and older said they would continue to live in South Africa no matter what. Some 65% of respondents aged between 15 and 24 years agreed with that sentiment; this rose to 74% in the age group 25 to 44 years old and 75% in the age group 45 to 54 years old.Of those aged 15 to 17, only 18% planned to live in another country; 9% of those aged 18 to 24 shared that sentiment, and just 6% of the 25- to 44-year-olds agreed.The crucial socio-economic challenges identified in South Africa were crime and unemployment.last_img read more

U.P. Cabinet okays Prayagraj

first_imgThe Uttar Pradesh Cabinet on Tuesday adopted the proposal to rename the historical city of Allahabad as Prayagraj, a move opposed by the Opposition parties in the State.The State government said it was only restoring an old name to the city. Today, the BJP government had rectified the mistake made by Akbar,” a BJP spokesperson said.Keeping in view the feelings and emotions of the people, Allahabad had been renamed Prayagraj by our government. Five hundred years ago, the name of the place was Prayagraj as it was at the Triveni Sangam [a confluence of three rivers],” Mr. Adityanath said later in Gorakhpur.“Those who are opposing this are not aware of their history, culture and traditions and we can’t have hopes from them,” he told presspersons during at visit to the Budhiya Mata temple in Gorakhpur. There are many Prayags on the bank of the sacred rivers coming from the Himalayas, but this place is Prayagraj (the leading one among them), the Chief Minister said.Before the CentreThe proposal would now go to the Centre before the city is officially renamed, though an Uttar Pradesh Minister seemed to suggest the change had already come into effect.“I am happy to say Allahabad will now be known as Prayagraj,” senior Uttar Pradesh Minister Siddhartha Nath Singh told presspersons after the Cabinet meeting chaired by the Chief Minister. “The government has announced this decision. It has come into effect from today, Mr. Singh said. “There is a process to carry out changes and the departments concerned will undertake it.” The State government would write to the Centre, he said.Samajwadi Party president Akhilesh Yadav had earlier criticised the move.The Congress had also opposed it, saying the name change ignored the history of Allahabad, which played a significant role during the Independence struggle.Congress spokesperson Onkar Singh said the region where Kumbh Mela was held was already called Prayagraj. The State government could make that a separate city but Allahabad’s name should not be changed.However, Mr. Siddhartha Nath Singh said the move would help highlight Indian culture internationally.last_img read more

Why did Sajid Khan thank his stars for Himmatwala debacle

first_imgDirector Sajid Khan’s Himmatwala remake was a flop and now he blames the film’s failure on his arrogance.”I am a changed man now. I was very arrogant then and I was talking anything to get attention and make statement. Now I am back on track and thank god Himmatwala flopped. In the middle, I lost it completely,” Sajid told reporters during the press conference of his next Humshakals.Sajid Khan’s Humshakals is slated for a June 20 release”I wanted people to respect me as a filmmaker. Heyy Babyy did well, then Housefull did well, so I wanted people to take me seriously. I am glad Himmatwala didn’t work,” he added.Though his Humshakals is yet to hit the screens, it is under scrutiny for being a remake of Comedy Of Errors.But shooting down the reports, Sajid said his film has “nothing to do with that film”.The star cast – Saif Ali Khan, Riteish Deshmukh, Ram Kapoor, Tamannaah Bhatia, Esha Gupta – was present at the event.However, Bipasha Basu skipped the event and Sajid said that she is “unwell”, but she will “attend other events and interviews”.It is being reported that Bipasha will not join the promotional activities of the film.When asked about it, Sajid’s response was that “it’s not true at all. Truth will come out one day. No one can hide it.”Humshakals is slated for a June 20 release.last_img read more

Test captaincy doesn’t come naturally to anyone: Stephen Fleming

first_imgFleming backs Team India to bounce back against England in the ODI seriesMS Dhoni may just be two tests losses away from touching Stephen Fleming’s ignominious record of most away test defeats as captain but he finds support from his CSK coach who advocates Indian cricket stakeholders to take a balanced view of things over their next test captain.In an interview to India Today.in Fleming backs the Dhoni led Indian one day outfit to bounce back against England, although he admits they will be uncomfortable after the test losses. Counting himself out in the race for Indian coach, he also says it would be in the best interest of Indian cricket if Virat Kohli strives to be the best batsman he can be and not necessarily the skipper.Q. Stephen, you have said you spend three months a year in India with the CSK. Would one get to see a lot more of your here? Should an opportunity arise would you want to be Indian cricket coach?A. No. I am happy with the CSK role. It works well with the family situation. I know how much travelling is there with Indian team and that’s not me for the moment.Q. You have spent a lot of time with Dhoni as a CSK skipper. Do you believe he is still the right man for the job. Also do you think test captainship comes naturally to him?A. I don’t know if test captainship comes naturally to anyone. It’s hard work and when your team does not do well you feel the pressure and responsibility. He batted well which is a good sign. If he was playing badly and the team was doing badly he would be under some real pressure. He’s got that decision along with the BCCI as to what future holds for him whether its all forms of the game or just the shorter version with the World Cup coming up. There are lots of questions I am sure which are being asked and he’s in the best place to answer it.advertisementQ. Virat’s worst test tour has coincided with India’s poor loss to England. Else do you think it could have been a case for him taking test leadership over from MS Dhoni?A. Virat will be dissapointed with his show. There are very high expectations of him and he is one of the best players in the world which he still is, a bad series in England or anywhere else does not make you any lesser. He will make some adjustments and will be better off for it. Whether that takes him to captainship, I am not sure. Being the best batsmen he can will be the best thing for Indian cricket right now.Q. How much of a blame should Duncan Fletcher take for India’s losses? The test team has never won away during his reign.A. I am a coach, and am not going to bad another coach. But more seriously it’s a hard job. Responsibility lies with the players which often gets overlooked. The coach and the captain gets targeted. But the players will be dissapointed with the way they played. There was a lot expected of Virat and Pujara. Vijay played quite well but there are some real high profile players who have put some good numbers in the past 12 months and collectively they have had a very bad tournament. How deep you want to run with that whether it’s support staff whether it’s your academies that’s a case for the BCCI.Q. Do you think the test loss will hurt their chances in the one dayers?A. No I don’t think so. They will be looking forward to the one dayers. It’s generally agreed  that they are more suited to the one day game at the moment. They are world champions and they will be on the run. But they will be uncomfortable just like England were in the second half of the test series. They will come bouncing back and I would be surprised if they didn’t.last_img read more

Queen dismayed at UK politicians inability to govern Report

first_imgLondon: Queen Elizabeth II is reportedly “dismayed” at the inability of Britain’s political class to govern properly, according to a UK media report. The 93-year-old monarch, who traditionally stays publicly neutral on political matters, is believed to have made the comments at a private event shortly after David Cameron’s resignation as British Prime Minister following the Brexit referendum in June 2016. A royal source described by ‘The Sunday Times’ as “impeccable” told the newspaper that the Queen’s frustration has only grown since then. Also Read – Saudi Crown Prince ‘snubbed’ Pak PM, recalled jet from US “I think she’s really dismayed. I’ve heard her talking about her disappointment in the current political class and its inability to govern correctly,” the source is quoted as saying. “She expressed her exasperation and frustration about the quality of our political leadership, and that frustration will only have grown,” said the senior royal source, who claims to have witnessed the Queen’s rare conversation on politics. The revelation comes as there is growing media speculation amid Buckingham Palace and Downing Street holding discussions about how to keep the monarch out of any looming constitutional crisis over Brexit and Prime Minister Boris Johnson’s pledge to leave the European Union (EU) by the October 31 deadline, with or without a deal. Also Read – Record number of 35 candidates in fray for SL Presidential polls There are fears that politicians will try to force the Queen to get involved if Johnson loses a no-confidence vote early next month and refuses to step aside. It is feared he would instead call a General Election after a forced no-deal Brexit, leaving MPs with no recourse of preventing the EU crash-out without any agreement in place. UK shadow chancellor John McDonnell has threatened to send Labour leader Jeremy Corbyn to Buckingham Palace “in a cab” to tell the Queen that the Opposition party is “taking over” if Johnson were to refuse to resign after losing such a no-confidence vote. Under the UK’s Fixed-term Parliaments Act, the Queen could be required to ask Corbyn or another senior politician to form a government that can command the confidence of the House of Commons. Buckingham Palace has declined to formally comment on what is feared to further mount into a constitutional quandary in the coming weeks.last_img read more
