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.”

Wednesday, an over-90-year-old Manns Mitre 10 hardware store, run by Alex P Mann Pty Ltd, closed until further notice after a rent dispute in Port Adelaide, South Australia. The rent dispute involved $315,060.70 of rent for months of September 2012 to January 2013 unpaid to the landlord, Fourteen Sails Pty Ltd. The site was distrained. The store had to fire about 40–50 employees without a warning in advance.

The store was closed three days before Australia Day, January 26, Saturday.

The store administrator, Tim Clifton, said they had to ring the workers out of the blue: “I was advised the landlord had distrained for unpaid rent over the business and that left the directors in the position where the business was untenable. I presume at this stage trading was poor and the company just didn’t have the money to pay the rent. … Unfortunately they had to terminate their employment this morning and we’ve rung them all. We’ll do our best to get them their entitlements under the government schemes, and we calculate what they’re owed in the next few days and hopefully get that underway for them. … It’s a sad day. It’s a sign of the times isn’t it. Things are tough out there.”

Construction, Forestry, Mining and Energy Union state secretary Dave Kirner said workers were not allowed to collect their personal belongings left inside of the store: “I spoke with a worker who said the locks have been changed, they were asked to leave and all their personal belongings are in there”.

On Saturday, Wikinews took photos of the documents available at the store entrance. The rent dispute details and an inventory were available for everyone to read. During the ten minutes of taking photos, around seven people visited the closed entrance and read the documents a first time. One of them commented, “oh hey, Bunnings will be stronger”.

The store owner, Jarred Spearman, reported negotiations ongoing with the landlord and said he would “hopefully try to work [our] way out of this … We are pretty lucky to have the customers and staff we had”.

Port Adelaide Mayor Gary Johanson said the loss of the store is a significant loss as Port Adelaide is being redeveloped: “Their staff were extremely good, the service levels were high, the store was always well stocked and it was a great example of a family business. That will be a great loss to the Port.” “The landlord is not at fault here. The landlord is acting within their rights. … This is the sort of thing we cannot afford to lose if we’re serious about the Port being redeveloped. This is not a multinational company. This is a franchise of a bigger company but it is a family franchise and it employs a lot of staff. The staff that they employ are local people and they’re employing large amounts of staff in relation to their turnover. We need to take stock of what local businesses we have left and say, how can we ensure they stay with us?”

On Wednesday, various cities in the Indian state of Karnataka observed Karnataka Bandh ^{((en))English language: ?Karnataka closed}, as people protested for central government to sort out the dispute of water share for the Mandovi river, also known as Mahadayi, which has been going on for decades. Bus service in Karnataka’s capital Bangalore was at a complete halt, however, the bandh was not strictly followed in southern parts of Karnataka, including in Mysore.

The 77 kilometer (about 48 mile) river originates in northern Karnataka, and flows through Goa. Almost two thirds of the river’s length is in Goa. Requests for 7.6 billion cubic feet (about 175,000 acre-feet) of river water to be released to Belagavi, Bagalkot, Dharwad and Gadag districts were made by Karnataka government for seventeen years. There were plans for Karnataka to build canals for storing water for those four districts, which are prone to drought, which were stopped by judge JN Panchal in July 2016, asserting the affects on environment.

As a result of bandh, various schools and colleges announced a holiday, and Bangalore University postponed their exams. Deputy Commissioner Ramprasath Manohar said, “Schools and colleges in Ballari district of Karnataka will remain closed in the light of the state-wide bandh called by the pro-Kannada organisations and farmers’ welfare associations”.

Indian Medical Association wore a black band for the support, as the medical services we not interrupted in Banglaore, nor were auto-rickshaw services. Hotels remained open at some places. Movie cinemas and malls were also to stay closed.

Kannada actor Prakash Raj uploaded a video on Twitter saying, “First of all, all political parties must stop politicising it. We Kannadigas have a right over the water that flows past Kalasa Banduri. In a democracy, once a political party comes to power, it is no longer just a political party, but a party that is duty-bound to work for the people it represents. Any party that keeps saying — ‘our party is ruling at the Centre, so we will take the water through political means’ — is telling a blatant lie. This is a pro-people agitation. Please don’t do politics over people’s fundamental rights. My request to all parties — please leave your political ideologies aside, put aside these attempts to beg for votes. We must come together and stand together to put pressure for our rightful share in the water. Let’s agitate and ensure our rights are given to us.”

The Bhartiya Janta Party (BJP) claimed the timing of the bandh was a political ploy to distract from party president Amit Shah’s scheduled rally on the same day in Mysore.

Vatal Nagaraj, who heads the pro-Kannada umbrella group Kannada Okoota which called the bandh, thanked public and private organisations for their observance of the bandh and claimed it was “total” across Karnataka. He said he visited different parts of the city Thursday morning.

Speaking to Press Trust of India, Deryk Natto, the managing director of Goa’s state bus service Kadamba Transport Corporation Limited, said, “The services to Karnataka have been suspended for a day due to the strike called by them. The services will resume once the strike is called off”. 23 buses bound to Karnataka were suspended.

Due to the strikes, traffic in Bangalore was lesser than usual. Unlike the case with buses, Namma Metro service in Bengaluru was functioning. A spokesperson of the metro service said, “If and only if there is a hindrance to safety of the passengers, we will inform the police and stop services.” Police arrested protestors at the KSR Bangalore Railway station who attempted to disrupt the railway facilities. 15000 police officials were assigned for security measures in Bangalore alone.

In Mysore, a number of shops were open at 10:30 AM, and there was usual traffic. Pharmaceutical shops remained open, however, some shops were closed. Protesters forced some shops to close, but classes in The National Institute of Engineering continued. Former Chief Minister B.S. Yeddyurappafew said a few days ago, “We fully support the Mahadayi project. There is no need for a bandh. Bandh is only needed in the areas where people are suffering.”

A person from Mangalore told Wikinews there was no effect of bandh in Mangalore, and some restaurants and hotels had posters, which roughly translate, “We feel sorry that you do not have water. But stop hurting our livelihood by organisining these bandhs” ^{((kn))Kannada language: ?????? ??????? ???? ??????. ????? ??? ??? ???? ???? ???? ??????? ???? ????????! ? ???? ???? ?? ???? ??????????}“.

A bandh is scheduled on February 4, when Indian Prime Minister Narendra Modi is to address a BJP rally in Bangalore.

The Svalbard Global Seed Vault, a vault containing millions of seeds from all over the world, saw its first deposits on Tuesday. Located 800 kilometers from the North Pole on the Norwegian island of Spitsbergen, the vault has been referred to by European Commission president José Manuel Barroso as a “frozen Garden of Eden“. It is intended to preserve crop supplies and secure biological diversity in the event of a worldwide disaster.

“The opening of the seed vault marks a historic turning point in safeguarding the world’s crop diversity,” said Cary Fowler, executive director of the Global Crop Diversity Trust which is in charge of collecting the seed samples. The Norwegian government, who owns the bank, built it at a cost of $9.1 million.

At the opening ceremony, 100 million seeds from 268,000 samples were placed inside the vault, where there is room for over 2 billion seeds. Each of the samples originated from a different farm or field, in order to best ensure biological diversity. These crop seeds included such staples as rice, potatoes, barley, lettuce, maize, sorghum, and wheat. No genetically modified crops were included. (Beyond politics they are generally sterile so of no use.)

Constructed deep inside a mountain and protected by concrete walls, the “doomsday vault” is designed to withstand earthquakes, nuclear warfare, and floods resulting from global warming. Norwegian Prime Minister Jens Stoltenberg called it an “insurance policy” against such threats.

With air-conditioned temperatures of -18 degrees Celsius, experts say the seeds could last for an entire millennium. Some crops will be able to last longer, like sorghum, which the Global Crop Diversity Trust says can last almost 20 millenniums. Even if the refrigeration system fails, the vaults are expected to stay frozen for 200 years.

The Prime Minister said, “With climate change and other forces threatening the diversity of life that sustains our planet, Norway is proud to be playing a central role in creating a facility capable of protecting what are not just seeds, but the fundamental building blocks of human civilization.” Stoltenberg, along with Kenyan Nobel Peace Prize laureate Wangari Maathai, made the first deposit of rice to the vault.

“It is very important for Africa to store seeds here because anything can happen to our national seed banks,” Maathai said. The vault will operate as a bank, allowing countries to use their deposited seeds free of charge. It will also serve as a backup to the thousands of other seed banks around the world.

“Crop diversity will soon prove to be our most potent and indispensable resource for addressing climate change, water and energy supply constraints and for meeting the food needs of a growing population,” Cary Fowler said.

Amid the confusion surrounding today’s London blasts, officials have urged the public to avoid the city if possible to allow emergency services to operate more quickly.

All rail and underground stations remain closed, although efforts are being made to reopen them. Air links are now closed at Stansted, Heathrow, Gatwick and London City airports.

Those trying to contact friends and family via mobile have struggled as the largest mobile networks, Vodafone, O2 and Orange, have all suffered from full capacity on several occasions this morning meaning voice calls failed.

On the web, websites such as BBC, TfL and the G8 2005 website struggled for a short time at one point this morning under the strain of so many web users visiting them. The national grid has said that it has sustained no damage to the electricity network.On the Traffic England site run by the Highways Agency, London has been marked as a ‘Closed area’.

The Royal Mail is warning customers that mail collections and deliveries across the UK will be disrupted because of the incidents. Royal Mail vehicles will not be moving in or out of London, or between Royal Mail sites in central London for the remainder of today. At least 25 per cent of the UK’s mail moves through London, even if its end destination is elsewhere. Disruption may therefore be felt throughout the UK. Royal Mail expects to issue further information later today.

Bus services in Zone 1 have resumed as of 16:00 BST.
