US scientists find evidence for group selection of spider colonies in the wild

Saturday, October 4, 2014

US biologists from the Universities of Pittsburgh and Vermont have found that social spiders of species Anelosimus studiosus exhibit apparent group selection, determining a trait affecting the colony’s survival. According to one of the researchers, this is the first experimental evidence of group selection in wild populations driving adaptation to local conditions. The study was published in journal Nature on Wednesday.

The researchers found that, depending on the availability of resources at the location of the colony and the size of the colony, the spider colonies have a different composition, promoting colony survival. The collective colony trait the scientists analyzed is the shifting ratio of “aggressive” and “docile” female spiders. The authors suggest two possible causes of colony extinction from inappropriate ratio in a large colony, depending on the availability of resources: egg cannibalism when there are few resources and a high proportion of “aggressive” female spiders, and social parasites when there are abundant resources and a high proportion of “docile” female spiders.

To check whether the self-regulation of spider colonies can be considered an adaptation to local conditions, the scientists placed artificially assembled colonies in different locations, with resource availability similar to or different from their home location. In cases of high risk of extinction, colonies self-regulated the ratio of “aggressive” and “docile” female spiders to match not resource conditions of the site they were placed at, but resource conditions of the home site from which they were taken.

Coauthor Jonathan Pruitt, University of Pittsburgh assistant professor of behavioral ecology, said, “These findings provide compelling evidence that the mechanisms that colonies use to regulate their compositions are themselves locally adapted, presumably because of the survival advantages they confer to the colony”. “They’re continuing to make the phenotypes, the trait at a group level, that would have been advantageous if they had stayed home […] But they seem to have no idea that they’re at a new site and that what they’re doing is going to doom the whole colony. All the friends die”.

Coauthor Charles Goodnight, at the University of Vermont, said: “Biologists have never shown an adaptation in nature which is clearly attributable to group selection […] Our paper is that demonstration.”

Rokot launches three Gonets satellites

Friday, May 23, 2008

Three Gonets satellites have been launched by the Russian Space Forces atop a Ukranian-built Rokot carrier rocket. Lift-off, from site 133 at the Plesetsk Cosmodrome in Northern Russia, occurred at 15:20:09 GMT this afternoon.

The three Gonets satellites will be used to provide store-dump communication services. This is the second launch of modernised Gonets-D1M satellites. They will be operated by Gonets SatCom, an organisation which was previously part of the Russian Federal Space Agency, but which was privatised in 1996. Whilst Gonets is a civilian system, it has been reported that these satellites will also be used for military applications. Reports have suggested that the satellites have received military designations of Kosmos-2437, 2438 and 2439 under the Kosmos system. Such designations have previously been assigned to, and in some cases later removed from, civilian satellites.

A small technology demonstration satellite, Yubileiny, was also launched. It was built to celebrate the 50th anniversary of the launch of Sputnik 1, and will be operated by NPO PM. It will broadcast audio and visual programmes on amateur radio frequencies, detailing the history of the space programmes of Russia and the Soviet Union, as well as signals imitating those of Sputnik 1.

The Rokot is a small carrier rocket derived from the UR-100 missile. Its upper stage, the Briz-KM, is a scaled-down version of the Briz-M upper stage used on Proton rockets. This is the first launch of a Briz upper stage of either type since the failure of a Briz-M during a March Proton launch, which left the AMC-14 satellite stranded in Medium Earth orbit.

This is the 25th orbital launch of 2008 in spaceflight, and the 13th launch of a Rokot. The next Rokot launch is scheduled for early-mid September, with the GOCE satellite for the European Space Agency.

Furniture Storage To Save That Luxury Italian Furniture

Furniture Storage To Save That Luxury Italian Furniture by Anthony TaylorFurniture storage is a great way to keep furniture safe and secure when you are moving or are renovating your house. However, before you store the furniture you should properly prepare and pack it to make sure it retains its shape, beauty, and shine when it is ready for use the next time. You can use the tips given below to protect your furniture, beds, sofas, and tables while they are in storage. Choosing A WarehouseChoose storage spaces that have climate controlled units or dehumidifiers installed to protect stored items from the elements. You should compare the prices and storage terms of various firms. Location, hours of operation and price are other important considerations to look for in self storage. Take a look at the storage units before you sign a contract. Call your insurance company to check for any policy on stored furniture. A storage unit which has wide doors and safe walls between lockers should be chosen. Also, make sure that there are no signs of water damage in any part of the building. Furniture should be kept dry because moisture is the main cause of damage to stored furniture. You should have many thick plastic sheets handy. These sheets should be laid on the floors of self storage units to keep moisture and humidity at bay. Moisture can cause mold growth which is harmful for furniture. Furniture storage can also be done on top of wooden pallets which let the items breathe and save them from moisture. PackingGood packing can ensure that the furniture will be as beautiful as it was when it was stored. As a first step, you can disassemble beds and tables before storing. You can apply a coat of wax to protect its sheen. All the screws, bolts, and nuts should be placed in a clear plastic bag and tied to the bed frame. A quilt can be wrapped around tabletops and headboards to prevent denting and scratching. Although storage facilities are much better than garage storage and also have provisions for boat storage, one needs to be careful while packing things for storage. For instance, a cloth or a towel can be placed over the contents of each drawer to prevent dust from entering the furniture. Wrap the light bulbs and shades from lamps, in towels or newspapers. Computers and electronic items can be stored in their original boxes. All the accessories like cords, modems, speakers, and microphones should be stored together so that they do not get lost. How To Store Goods In The Units?Once all the things have been carefully packed, the next step is furniture storage in the units. The items should be organized in a manner that the biggest items are placed in the locker first and the smaller items are filled in the extra spaces. Refrigerators, ovens, washers, and dryers can be placed upright to save space. Leave the do0ors open to prevent an unpleasant smell from developing. Cover the sofas with a cotton sheet and place them on a plastic sheet. Light chairs can be stacked on top of the other. But secure them carefully so that they don’t trip and damage other items. You can use mattresses as buffers between each item.Secure your furniture storage unit with a strong combination lock. Check on your furniture at least once every month and make sure it is stored near your home or office Get the most out of furniture storage, car storage, and RV storage at Storage Mart.Article Source: eArticlesOnline.com

Iran’s morality police crack down on un-Islamic dress

Wednesday, April 25, 2007

The Iranian police forces have faced criticism from Ayatollah Hashemi Shahrudi, the head of the judiciary who was appointed by Grand Ayatollah Ali Khamenei, for their re-invigorated campaign to do away with un-Islamic dress.

Ayatollah Shahroudi proclaimed, “Tough measures on social problems will backfire and have counter-productive effects.” Others have, of course, made it clear that un-Islamic dress can lead to moral corruption, engender innumerable vices, and hurt the Islamic character of the nation.

Some believe that no one had any issue with the creation of an Islamic atmosphere. The core of the matter revolves around the implementation of the Islamic dress code; additionally, heavy-handed measures should be shunned. For instance, Mehdi Ahmadi, information head of Tehran’s police, told Al Jazeera: “Some citizens may complain about the way the law is being enforced but they all agree with the plan itself.”

According to one student, “You simply can’t tell people what to wear. They don’t understand that use of force only brings hatred towards them, not love.” Nevertheless, Hojatoll-Islam Mostafa Pour-Mohammadi, Iran’s interior minister who is in charge of policing, prognosticated positive feedback from the populace when he said, “People are unhappy with the social and moral status of the society. They expect that the fight against social insecurity be properly implemented.” Thus, Hujjat al-Islam Pour-Mohammadi re-iterated the necessity of proper implementation and methodology towards the restoration of morality in the Islamic Republic. Islamic officials and religious people affirm that this is indispensable to promote righteousness, curb sin, and bring open sinners to justice.

Following the Islamic Revolution in 1979, hijab became mandatory in Iran for every woman including foreigners after over 98% of citizens voted for an Islamic government. Women may face caning up to 74 strokes for failing to observe hijab. In this recent crackdown, the authorities have arrested many citizens throughout the country. Not only have women been taken into custody for their hair being uncovered on their foreheads and tight clothes that show body shapes, For men they need to cover from knee to their waist as according to Sharia. Even a foreign journalist was detained because the photograph on her press card was indecent.

It has not been clear whence the directive for the re-newed clampdown emanated. Some have blamed Mahmoud Ahmadinejad while Gholam Hossein Elham, the government spokesman, stated to reporters, “The police work as agents of the judiciary to confront crimes. The government as an executive body does not interfere in the affairs of the judiciary.” The following pre-election speech seems to corroborate this latter statement:

In reality, is the problem of our people the shape of the hair of our children? Let our children arrange their hair any way they wish. It doesn’t concern me and you. Let you and me overhaul the basic problems of the nation. The government should fix the economy of the nation and improve its atmosphere…[It should] better psychological security and support the people. People have variegated tastes. As if now the arch obstacle of our nation is the arrangement of our kids’ hair and the government disallowing them <He chuckles>. Is this the government’s responsibility? Is this the people’s merit? In actuality, this is the denigration of our people. Why do you underestimate and belittle the people? It is the real issue of our nation that one of our daughters donned a certain dress? Is this the issue of our nation and the problem of our nation?

Former Russian spy Litvinenko dies, radioactive poisoning suspected

Friday, November 24, 2006

Mr Alexander Litvinenko, reputed to have been an Ex-Russian spy who had defected to Britain, died last night in mysterious circumstances. He had alleged many associations between people in high places and organised international crime, implying that President Putin and Romano Prodi among others had been involved personally. He had sought political asylum in UK in 2000 and became a naturalised citizen in October this year, just weeks before his death.

Mr Litvinenko was said to have been investigating the shooting of Russian journalist and human rights activist Anna Politkovskaya, a well-known critic of Russian activities in Chechnya, in her apartment in Moscow October 7, 2006. It is reported that he had met two Russians in an hotel room, one said to be former member of the KGB in conneciton with the affair and he went on to meet Mario Scaramella at a sushi bar in Piccadilly where some papers were exchanged. Some hours after this he was taken ill.

Mr Litvinenko was admitted to Barnet General Hospital, north London on November 1, 2006 complaining of feeling sick. By November 11, he was said to be suffering from serious poisoning. A week later he was transferred to University College Hospital in central London. A week later he was said to have been poisoned by ingesting thallium, once used in rat poison, but, in the opinion of some doctors, there were signs of radioactive poisoning, including loss of weight and shedding of hair. Various explanations of his condition were offered. Last night he suffered a heart attack, after having left a message blaming President Putin for having him killed.

The radioactive isotope polonium-210 was found in his blood and urine as reported by the United Kingdom’s Health Protection Agency. The post-mortem was cancelled. Subsequently the Agency examined conditions in the hospitals in which Mr Litvinenko has been treated. Police visited the Itsu sushi restaurant in Piccadilly, his home in Muswell Hill and the Millennium Hotel, Grosvenor Square where the meeting on November 1 had been held. Traces of radiocactivity were found in all three places. It is speculated that the polonium was probably eaten by Litvinenko as a substance that could be combined with a salt-like substance, such as polonium nitrate.

It was reported that a meeting had been held in Cabinet Office Briefing Room A (COBRA) used for high level emergency planning and control, to consider the implications of these events. The Foreign Office asked Moscow for a response to the accusation of Russian involvement and President Putin himself dismissed the allegations saying (before the cause of death had been established) that there was no proof of an unnatural death and that the case was being used as a “political provocation”.

Calls for bottled water bans grow in Canada

Saturday, August 23, 2008

London, Ontario is the latest in a string of Canadian cities to have acted on increasing public demand to ban bottled water. On Monday, the decision to eliminate bottled water sales in city-run facilities was passed by London’s city council with a vote of 15-3 in favour. The move was driven by a desire to reduce waste and shipping, have a lower impact on the environment and promote tap water as a cheap and safe alternative.

London’s new restrictions will be implemented over the next several months in buildings that are already equipped with water fountains. Bottled water will still be permitted at many city-run events, such as upcoming summer festivals. Privately-owned retailers will not be affected by the ban.

Other cities, such as Vancouver, Ottawa and Kitchener, that are already engaged in debate on the issue, may now be watching London carefully for how the ban plays out. Other areas have already begun to phone London with questions on the details of its new regulations. Toronto has begun taking a look at bottled water packaging as part of its waste diversion strategy, and its public school board is looking into the possibility of a total restriction on bottled water sales.

In recent years, an awareness of the energy that is required to manufacture, transport and recycle the product has spread nation-wide. Proponents of the ban point to the fact that it can produce as much as 150 times the volume of greenhouse gas when producing bottled water as compared to supplying the same volume of tap water. They also point out that the water that goes into bottled water products is not inspected as frequently as tap water in Canadian cities.

Some have taken this cause to heart more than others, such as British Environment Minister Phil Woolas, who called the use of bottled water “morally unacceptable.” Restaurant critic Giles Coren of The Times of London criticizes those who use the product as “the new smokers.”

Canada’s beverage industry has come down with criticism on the increasing opposition to bottled water. Spokesman Scott Tabachnick for Coca-Cola Co., which produces Dasani brand bottled water, commented on the convenience of the product: “It’s hard to bring your kitchen sink with you.”

It’s hard to bring your kitchen sink with you.

Vancouver City Councillor Tim Stevenson thinks that bottled water’s time has come and gone: “Bottled water companies have had a fabulous ride on an unnecessary fad.” Vancouver officials are still determining how bottled water restrictions, which have been voted for by the City Council, can be phased in.

Next month, the city is planning to initiate a marketing campaign encouraging Vancouver residents to choose tap water and to remember to carry reusable drinking containers whenever possible.

Renowned environmental activist Dr. David Suzuki has praised London’s decision, saying that it represents a turning point for people’s perceptions on the issue: “I’m really delighted that London has done this because it really makes us focus on some fundamental issues.” He hopes that someday people will “look at anyone who hauls out a bottle of water and say, ‘What the hell’s wrong with you?'”
