LACKING QUALITY Former Rivoli and Waterhouse coach Calvert Fitzgerald was critical of the overseas-born players in the squad, arguing that they lacked real quality and add nothing to the team. “The Jamaica national team is mainly made up of players from England who play in the lower leagues. A lot of them not even start in the championship. So it simply means they could not be all that good. None of them can land a contract out of England,” he said. Powell has been singled out for his performances but Rudolph Speid, the former Kingston and St Andrew Football Association president and current technical director at Red Stripe Premier league campaigner Cavalier,was a little more forgiving. “The public is against Alvas not for his playing. Everyone is looking that he walked out of the team and got back without a minute suspension, but I don’t think he is a bad player. He has been found wanting, but he is young,” he reasoned, before giving his assessment of the team’s chances in their remaining two group games. “Panama has everything in their favour. They have the points, they have the goal difference, they are at home and physically, we cannot bully them, so it’s for the coach to choose the right tactics,” Speid said. “We will definitely need help from other teams, most notable from Costa Rica, and we have to be perfect in our two games.” Powell has also come under pressure for his lapses defensively, but Speid put his mistakes down to inexperience. Schafer was contacted yesterday, but declined to comment. Meanwhile, Jamaica sits third in their group on four points – three less than Panama, where they will travel to on September 2; and six behind leaders Costa Rica. Haiti, who will play in Kingston on September 6, are in last place on one point. Reggae Boyz head coach Winfried Schafer and his technical staff have been given a failing grade by local coaches, after the team’s unconvincing showing in recent times, underlined by poor results in back-to-back World Cup qualifiers against Costa Rica. Defensive weakness, incorrect tactics, apparent discontent in the camp and the presence of what some have called substandard overseas-born players, are among the major issues mentioned. It has been suggested that the return of defender Alvas Powell to the fold – unpunished, after walking out on the team in the Gold Cup – is a cause of the contention within the squad. The team started well against ‘Los Ticos’ in the first game last week Friday, playing the best football they have played in some time and taking a 1-0 lead into the break. Costa Rica secured the equaliser for a 1-1 draw before outclassing the Jamaicans 3-0 in the reverse fixture. Former national assistant coach Bradley Stewart questioned some of Schafer’s choices, in particular his decision to keep defender Adrian Mariappa on the field in last Friday’s draw. “Mariappa got injured and the best thing he (Schafer) should have done is take Mariappa out and put in Jermaine Taylor, as a fit Taylor is as good as a fit Mariappa,” he said. “If you are a quality team you are expected to win your games at home, things are against you when you travel. It is always more difficult to beat a team at their yard that you cannot beat at your yard,” he stated in a grim outlook on the team’s chances to advance.

DOI: 10.1126/sciadv.aav8391 Explore further As the planet continues to warm due to human-related activities, scientists continue to look for ways to reduce greenhouse gas emissions. In this new effort, the researchers wondered if it might not be possible to reduce the amount of methane released by cattle. Livestock have been found to contribute up to 14.5 percent of such gases worldwide. Far less methane is released into the atmosphere each year than carbon dioxide, but methane is better at trapping heat.The researchers note that prior research has shown that the primary generator of methane in cows is the rumen—the first stomach. When a cow eats grass, it goes into the rumen, where a host of microbes reside along with other digestive materials. The host microbes work together to break down the carbohydrates via a fermentation process. As part of that process, hydrogen is produced by certain types of bacteria, and then archaea combine carbon dioxide with the hydrogen to produce methane. Contrary to common belief, most of the methane is belched out of the cow’s mouth.To find out if cows could be coaxed into producing and belching less methane, the researchers conducted a genetic analysis of the microbes that exist in the rumen of several types of cows from several sites across Europe. In all the team collected samples from more than 1000 cows. Study of their rumen microbiome showed that half of all of the microbes in them had 512 species in common. They also found that 39 of the microbes made up a core that plays a major role in determining not just how much methane is produced, but also how much milk. The researchers are now looking into the possibility of manipulating the cow rumen biota to see if it is possible to bring about changes that will result in less methane production.
