4 4 4 Jackson Martinez (Porto) – Click the arrows to view more strikers – The Colombian has gone goal crazy in Portugal, netting 60 goals in 91 games for Porto and has already admitted he would love a move to Arsenal the club he has supported all his life. The Gunners are understood to have held discussions with the 25-year-old but that was prior to Alexis Sanchezs arrival and since then things have gone a tad quiet. Martinez has made it known he would happily accept a move to the Emirates but it will take £35m to prise him away from Estadio do Dragao. Javier Hernandez (Manchester United) – The Red Devils forward has proven since moving to Old Trafford in 2010 that he has an eye for goal. A natural poacher, he is quite possibly the exact type of player Arsenal are crying out for. Currently he is one of six United players who are thought to be having their futures assessed by new boss Louis van Gaal. But should the Dutchman conclude his time is up, then Arsene Wenger should act quickly to snap up the Mexico international for what is likely to be only £7m. 4 Mario Balotelli (AC Milan) – Click the arrows to view more strikers – The difficult Italian striker is well known on these shores and Arsenal have been linked with a move for his services all summer. The Italy international Englands scourge in their World Cup match is thought to be available for £15.8million and while almost double the fee Liverpool are paying for Remy, he is younger and is considered more of an explosive star, both on and off the pitch. Wilfried Bony (Swansea) – Click the arrows to view more strikers – Liverpool and Arsenal have competed for various players this summer. Alexis Sanchez chose the Gunners while it seems Remy has opted for the Reds. Bony is another player both have cast their eye over with the Merseyside club reportedly agreeing terms for the Ivory Coast international but failing to meet Swanseas £20m valuation. Brendan Rodgers decision to bring Remy to Anfield indicates he is no longer interested in the Jacks forward and with the striker making it obvious he wants a move to a top six club, Arsenal could benefit from Liverpools failure to bring in the 25-year-old, who scored 25 goals in his debut season on English soil. Loic Remy and Arsenal were meant to be. It was always thought the French striker would head to the Emirates, particularly when he was spotted in the stands at the Gunners’ last home game of the season. But somehow it appears he is now on his way to Liverpool for £8.5m instead.It’s fair to say Gooners are used to Arsene Wenger’s dithering in the transfer market in recent seasons, but this one left a particularly sore mark as they always felt the QPR forward was bound to move to north London. Remy has history of doing the unexpected – QPR signed him from right under the noses of Newcastle, who thought they had a deal tied up – but while Arsenal fans are unimpressed by their failure to land the France international it should not be all doom and gloom.Wenger has since said he is not looking for new strikers but with plenty of time left in the transfer market, he could yet change his mind and as these players prove, there are still options out there for the Gunners.Click the arrows to view four forwards Arsenal could sign.
There’s more going on under your skin than you possibly realize.Lung brush: Working 24×7, microscopic cilia lining your bronchial passages sweep your lungs clean, allowing you to survive in an atmosphere filled with pollutants. Science Daily summarized a paper in Science that described “A Periciliary Brush Promotes the Lung Health by Separating the Mucus Layer from Airway Epithelia” (Button et al., Science, 24 August 2012: Vol. 337 no. 6097 pp. 937-941, DOI: 10.1126/science.1223012). Science Daily said,“The cilia are constantly beating, even while we sleep,” he says. “In a coordinated fashion, they push mucus containing foreign objects out of the lungs, and we either swallow it or spit it out. These cilia even beat for a few hours after we die. If they stopped, we’d be flooded with mucus that provides a fertile breeding ground for bacteria.”….The researchers used a combination of imaging techniques to observe a dense meshwork in the periciliary layer of human bronchial epithelial cell cultures. The brush-like layer consists of protective molecules that keep sticky mucus from reaching the cilia and epithelial cells, thus ensuring the normal flow of mucus….“This layer — this brush — seems to be very important for the healthy functioning of human airways,” according to Rubinstein. “It protects cells from sticky mucus, and it creates a second barrier of defense in case viruses or bacteria penetrate through the mucus. They would not penetrate through the brush layer because the brush is denser.”Respiratory diseases such as COPD are apparently caused by the collapse of this brush layer. The new findings, which replace old notions that the mucus rested on a liquid layer, may help people suffering from a variety of lung problems. The BBC News write-up added this comment:Prof Stephen Spiro, vice-chairman of the British Lung Foundation, said: “Mucus has a complex biological make-up and forms a vital part of the lungs’ defence mechanism against potentially harmful or irritating substances, which are inhaled as small particles.“Research such as this helps our understanding [of] how this system works, and of the complex mechanisms deep within our lungs which protect us from the atmosphere we breathe in.”The original paper did not mention evolution, except to say in passing, “Mucus clearance in the mammalian lung has evolved to trap and clear a wide variety of inhaled toxicants and infectious agents from airway surfaces,” passing the support for that claim to three other references. Neither Science Daily nor the BBC saw fit to include evolution.Muscle builder: Early reports about irisin, a newly-discovered hormone that mimics the effects of exercise by converting white fat into brown fat (see Live Science Jan. 2012) may not pan out, according to Nature this week (Timmons et al., “Is irisin a human exercise gene?”, Nature 488, 30 August 2012, pp. E9–E10, doi:10.1038/nature11364). Timmons et al. found only modest benefit in humans, particularly highly-active elderly people. No need to despair, though: Science Daily just reported a “hulk protein” that may allow humans to grow stronger without working out. Researchers found that mice with the Grb10 gene disrupted grow more muscular. Don’t turn in your gym membership just yet, though, the researchers warned: “the classic prescription still applies: lift heavy things, eat and sleep right, and have your hormones checked.” They hope, though, that further understanding of these genetic processes may help people suffering from muscle-wasting diseases.Protein attraction: Your body’s proteins need to work together. Cornell scientists have found how proteins can feel attractive forces as far as 20 nanometers, a considerable distance at their scale. It involves fractal-like patterns in cell membranes that form near the “critical point of the liquid-liquid phase separation of the cell membrane, which is the subtle temperature and composition point at which the two phases separate.” PhysOrg included this quote by Ben Machta, grad student and co-author of the study: “We were intrigued that it seems like biology does want to tune itself closely to this critical point.”Gift-wrapped neurons: Many neural cells come wrapped in myelin, a membranous, lipid-rich sheath that composes the “white matter” of the central nervous system. What does it do? “The myelin sheath around nerve fibres serves to speed up electrical nerve signals, Nature News explained. “But it turns out that it also supplies neurons with fuel to support their high metabolic activity.” In particular, “lactate provided by or through the myelin sheath is crucial for neuronal survival.” A diagram in the article reveals the complex interactions of astrocytes, oligodendrocytes, ATP and blood vessels in this feeding process. The finding “expands the roles of myelin sheaths,” the authors said. This is not necessarily the only known function of myelin, which “supports neurons in other, less-well-understood ways.” Source: Rinholm and Bergerson, “Neuroscience: The wrap that feeds neurons,” Nature 487, 26 July 2012, pp. 435–436, doi:10.1038/487435a.Work in your sleep: Sleep learning is possible, reported Science Daily, because while you rest and dream, your brain is creating associations and memories of what you perceive through the senses, and these associations remain after you wake up. Experiments at the Weizmann Institute of Science showed that sleeping participants given Pavlov-like associations of tones with odors retained the association when awake: when hearing the tone, they would breathe in deeply for memories of pleasant odors, but take short sniffs when the tone was associated with a foul odor – even when having no conscious memory of the association. Researchers believe this finding suggests that “we could probably learn more complex information while we sleep,” but they expect limits. Don’t place your homework under your pillow, for instance.

The AAP feels it can reduce sexually-transmitted diseases and improve boys’ health, such as reducing risk of penile cancer and urinary tract infections. Some disagree strongly with tampering with nature on philosophical or religious grounds; some worry about complications for the baby. Although still controversial, the AAP believes ” the medical benefits outweigh the risks of the procedure” and advises insurance companies to pay for it. Source: Nature News, August 28; see also Live Science, which also reported August 20 that a drop in circumcisions would boost health care costs.Circumcision remains a parental choice; if undertaken, it should be for health reasons, not religious reasons. For Christians, the apostle Paul declared that “circumcision is nothing and uncircumcision is nothing” in terms of ceremonial significance, “but keeping the commandments of God” is what counts (I Cor. 7:19). In Romans he proved that circumcision is no longer a requirement for pleasing God, from whom salvation is by grace alone through faith. In Galatians, he strongly condemned the Judaizers who insisted that Christians must be circumcised, declaring them to be hypocrites: “As many as desire to make a good showing in the flesh, these would compel you to be circumcised, only that they may not suffer persecution for the cross of Christ. For not even those who are circumcised keep the law, but they desire to have you circumcised that they may boast in your flesh. But God forbid that I should boast except in the cross of our Lord Jesus Christ, by whom the world has been crucified to me, and I to the world. For in Christ Jesus neither circumcision nor uncircumcision avails anything, but a new creation.” (Galatians 6:12-15). Nevertheless, he did have Timothy circumcised to avoid offense as the young disciple entered a ministry to a mixed church of Jews and Gentiles (Acts 16:1-3). Some people get really adamant about their positions for or against circumcision, but consider: God would not have required a seriously damaging procedure for his people the Jews in the Old Testament; they did, after all, do a pretty good job of being fruitful and multiplying. If you agree with the AAP that the benefits outweigh the risks, or if you have some pragmatic reason, like wanting your boy to fit the cultural norm, have at it. If you want your boy to remain all natural, you will not thereby displease God.We hope all the stories in this entry will remind us all how “fearfully and wonderfully made” we are (Psalm 139), from the level of the whole body all the way down to the individual proteins in our cells.

About 300 people of West Tripura district, who had fled the area after their homes were torched and looted over the alleged molestation of a girl, said on Saturday that they were scared to return.They alleged that the looting and ransacking of their houses in Lalit Bazaar locality under the Ranir Bazaar police station limit was instigated by Revenue Minister and prominent tribal leader N.C. Debbarma.Mr. Debbarma, president of the Indigenous People’s Front Tripura (IPFT), declined to comment on the charge. Prohibitory orders under Section 144 of the Cr.PC was promulgated in the area for 48 hours from 8 a.m. on Saturday, Sub-divisional Magistrate Subhasish Bandopaddhyaya said.A group of tribal youths started torching and looting houses only after the Minister’s visit on Friday, said the villagers who have taken shelter in a school. “The ransacking and looting of our houses started only after N.C. Debbarma visited the spot. He came here at 9 a.m. and looting of our houses started around an hour later,” 50-year-old Samena Khatun alleged.Scared to returnSulekha Khatun, aged 45, said, “My house was set ablaze, my belongings looted. I do not want to return. Let the police shoot me dead. I will not return.” The conflict began when a girl, along with her boyfriend, had come to Ranir Bazaar area on Thursday from a nearby locality to see Durga idols there and four youths allegedly molested her and snatched her phone. The girl and boy went back to their locality and returned with a large group of people who tried to attack the houses of those who reportedly molested the girl. The four accused were arrested on Friday but the attack on the village continued. A large contingent of police has been deployed in the area.
