FRESH VIGOUR United had dictated the pace of the game, showcasing a newly discovered vigour and passing precision, but only scored in the 61st minute. It was a passage of play that demonstrated the potential in Louis van Gaal’s side. The build-up involved interplay between Juan Mata and Anthony Martial. Then Cameron Borthwick-Jackson’s cross was teed up by Wayne Rooney for Jesse Lingard to volley on the turn into the net. “We continued with our good, attacking football,” said Van Gaal, whose side held Chelsea 0-0 at home in December. “We have created a lot of chances here at Chelsea. It’s a nasty away game, I think, and one that’s not so easy. “The last few years Manchester United haven’t won here, so it’s not an easy match and we took the lead with a fantastic goal. A fantastic cross also. Then you can control the game, but in the last quarter we gave it away.” On the south coast, though, Arsenal emerged from their January slump. Arsenal had failed to win in four league games and not scored in three of them until travelling to Bournemouth. Mesut Ozil scored his first goal since December’s reverse fixture against Bournemouth and within 90 seconds Alex Oxlade-Chamberlain ended a 17-month league goal drought. “We had four games without a win when you play at the top that’s a long period, so your confidence drops a little bit,” Arsenal manager Arsene Wenger said. Arsenal moved behind second-place north London rivals Tottenham on goal difference. Coming up for Arsenal next Sunday is a home match against Leicester, the surprise leaders which sent Manchester City tumbling to fourth by winning their encounter 3-1 on Saturday. “Leicester running away and us playing them next week, (makes) the game interesting,” Wenger said. “It was very important for us to win today.” LONDON (AP): A second stalemate of the season between Chelsea and Manchester United saw the fallen powers slip further from relevance in this unusual Premier League season. The 1-1 draw at Stamford Bridge did little to help either team yesterday, which began with Arsenal beating Bournemouth 2-0 to rise to third. United remain lodged in fifth and the gap to the fourth Champions League place has grown to six points. Chelsea remain in the lower reaches of the standings – 13th – closer to the relegation zone than their usual place among the top four elite. The one positive for Chelsea is that the ailing champions remain unbeaten since Guus Hiddink was brought in as manager until the end of the season in December to replace the fired Jose Mourinho. The Blues left it late to rescue a point against United. The game had entered stoppage time when Cesc Fabregas threaded a pass beyond a slipping Daley Blind to Diego Costa, who rounded goalkeeper David De Gea before netting the equaliser.

Cellular self-digestion process triggers autoimmune disease Because the central nervous system similar looks so similar across species, it has been assumed for some time that it likely evolved just once in a very early common ancestor. But recent studies have shown that may not be the case. In this new effort, the researchers sought to gather more evidence of multiple instances of nervous system development by studying invertebrates scattered across the evolutionary tree with different types of central nervous system architectures. To that end, they collected tiny specimens from multiple locations and studied their lineage. They report that some of them belong to an ancient lineage called Xenacoelomorpha, which had a wide variety of nervous system types. Some had no central cord, they note, while others, such as modern jellyfish, have multiple cords—and one species has a cord running along its back reminiscent of vertebrates.The team also looked at a gene called bmp, believed to be the gene that is responsible for kicking off the development of the nervous system. But another team had shown that in the acorn worm, it became active before the formation of the nervous system, suggesting other genes were also at play. After looking at the invertebrates they had collected, the team found other instances of the bmp gene becoming activated before the formation of nerve cords. They also found that blocking the protein that is produced when bmp becomes active did not prevent formation of the cord in some species. The group also found that other genes that have been associated with development of the nervous cord became active in some species that had no nervous cord at all.The researchers claim their findings show that the nervous system evolved in different creatures at different times, which means that it evolved more than once.

In their paper published in the journal Nature, the group describes their study of tiny sea creatures they collected from fjords in Norway and Sweden, from various sea floor locations, and from a site off the coast of Washington state, and what they found. Caroline Albertin and Clifton Ragsdale, with the University of Chicago, offer a News & Views piece on the work done by the team in the same journal issue. More information: José M. Martín-Durán et al. Convergent evolution of bilaterian nerve cords, Nature (2017). DOI: 10.1038/nature25030AbstractIt has been hypothesized that a condensed nervous system with a medial ventral nerve cord is an ancestral character of Bilateria. The presence of similar dorsoventral molecular patterns along the nerve cords of vertebrates, flies, and an annelid has been interpreted as support for this scenario. Whether these similarities are generally found across the diversity of bilaterian neuroanatomies is unclear, and thus the evolutionary history of the nervous system is still contentious. Here we study representatives of Xenacoelomorpha, Rotifera, Nemertea, Brachiopoda, and Annelida to assess the conservation of the dorsoventral nerve cord patterning. None of the studied species show a conserved dorsoventral molecular regionalization of their nerve cords, not even the annelid Owenia fusiformis, whose trunk neuroanatomy parallels that of vertebrates and flies. Our findings restrict the use of molecular patterns to explain nervous system evolution, and suggest that the similarities in dorsoventral patterning and trunk neuroanatomies evolved independently in Bilateria.
