Mice infested human settlements 15,000 years ago

  

Mice began infesting human settlements some 15,000 years ago in the Middle East, said a study Monday that suggested the little rodents have been scurrying underfoot far longer than previously thought.

As soon as hunter-gatherers began settling down rather than roving from place to place, house mice began to edge out their wild counterparts, said the study in the Proceedings of the National Academy of Sciences (PNAS), a peer-reviewed US journal.
“The research provides the first evidence that, as early as 15,000 years ago, humans were living in one place long enough to impact local animal communities—resulting in the dominant presence of house mice,” said co-author Fiona Marshall, a professor of anthropology at Washington University in St. Louis.
Previous research has pointed to the rise of farming as the starting point for transforming human relations with the animal world—particularly small mammals like mice.
But this study suggests “that the roots of animal domestication go back to human sedentism thousands of years prior to what has long been considered the dawn of agriculture,” said Marshall.
In hunter-gatherer villages in the eastern Mediterranean region, house mice were common more than 3,000 years before the earliest known evidence for agriculture, said the findings.
When hunter gatherers settled in one place, they provided shelter and regular access to crumbs and scraps.
Mice would learn to benefit from this and would stick around, marking an early phase of domestication.
Researchers focused on an ancient Natufian hunter-gatherer site in the Jordan Valley of Israel, where excavations have shown a wildly swinging ratio of house mice to wild mice during different prehistoric periods.
They studied variations in the molar shapes of fossilized mice teeth going back as far as 200,000 years.
At times when people were more likely to settle for long periods, the house mouse (Mus musculus domesticus) reigned over the short-tailed field mouse (M. macedonicus), and pushed most of them outside the settlement.
In periods of drought or food shortages, when hunter-gatherers were forced to move more often, the populations of house mice and field mice reached a balance.
“The findings provide clear evidence that the ways humans have shaped the natural world are tied to varying levels of human mobility,” said Marshall.
The study included researchers from the National Center for Scientific Research in Paris, France, and Lior Weissbrod of the University of Haifa in Israel.

Apple wins patent case in China

• Apple has won a trial against a Chinese phone maker in Beijing as a court overturned a ruling against Apple Inc. over iPhone patents, a media report said on Monday.

The Beijing IP Court ruled that the iPhone 6 and iPhone 6 Plus do not infringe on patents for exterior smartphone design held by a defunct local manufacturer, Shenzhen Baili Marketing Services Co, technology website marketwatch.com reported.
The disputes were over the exterior design of the iPhone 6 and iPhone 6 Plus models, which Shenzhen Baili claimed were a copy of their 100C smartphones.
Initially, Apple was handed an injunction to stop selling its iPhone 6 line in Beijing for alleged infringement.
Apple and Beijing-based phone retailer Zoomflight quickly filed an administrative appeal with the Beijing Intellectual Property Bureau and Apple was permitted to sell the phones until further review by the court.
The Cupertino-based company on Saturday opened a new Apple Store in Nanjing city of China which has a 90-by-30-foot glass entryway.
For the first time, customers can explore The Forum -- a place where the local community can gather and learn -- and The Boardroom -- a space for local entrepreneurs, developers and business customers to get hands-on advice and training.
Earlier this month, Apple announced it would invest $508 million in China to build two additional Research and Development (R&D) centres in Shanghai and Suzhou to boost local talent.
Apple's attempt to boost its presence in China began last September with the opening of its first R&D centre in Beijing's Zhongguancun Science Park, often referred to as "China's Silicon Valley".

With this investment, Apple will have a total of four centres in China.

Bangladesh-India defence coop framework finalised

•  Bangladesh and India are to sign a five-year memorandum of understanding (MoU) to formalise defence cooperation between the two countries, officials concerned confirmed.

The draft of MoU includes cooperation in the defence industry and joint initiatives for its development, defence technology, research and maritime infrastructure development.

Officials told Prothom Alo on Wednesday that the draft framework of the defence cooperation MoU between Bangladesh and India has been finalised after about three months of talks between the two countries.

If all goes according to the plan, the deal will signed during prime minister Sheikh Hasina’s visit to India in April, they added. According to the draft schedule, Sheikh Hasina is to arrive in New Delhi on 7 April on a four-day state visit to India. After her talks with the Indian prime minister, Narendra Modi, on 8 April, several agreements and MoUs are expected to be signed, including the defence memorandum.
Talks are reportedly on also for an MoU pertaining to the purchase of military equipment from India under a credit agreement for the first time. Once the MoU is finalised and signed, Bangladesh will purchase defence equipment worth about Taka 4,000 crore ($500 million) from India.
Officials of various ministries concerned have said that so far 49 agreements and MoUs have been discussed for signing during the prime minister’s forthcoming visit.
However, the long-unresolved Teesta treaty is not included among these.
The list includes nine MoUs including the one for defence cooperation. Till last week, so far 17 agreements and MoUs have been finalised. More are likely to be finalised in the next few days.
Officials of the foreign ministry said that so far there has been no indication of the Teesta treaty to be signed during this visit. If it is finalised at the last minute, that will be a dramatic development.
However, even if the Teesta deal is not signed, India may come up with a specific declaration regarding river basin management, the officials said.
India had proposed long-term agreement framework to consolidate defence cooperation between the two countries. Last December, India’s defence minister at the time Manohar Parrikar came to Bangladesh and discussed the issue with the prime minister Sheikh Hasina. After discussions at several levels, Bangladesh finally agreed to an MoU for defence cooperation rather than a long-term agreement. Bangladesh and India finalised the drat MoU in the first half of February this year.
In giving a formal shape to the existing defence cooperation, the armed forces of the two countries will show respect towards international and national laws, each other’s laws, relevant conditionalities, policies and customs.
In order to enhance the efficiency of officers in the defence sector, the two sides will exchange training, military experts, trainers and observers, military curricula and information. The two sides will organise cooperation in military equipment maintenance, and training pertaining to disaster and relief cooperation.
Talks will be held among the army, navy and air force regarding defence cooperation. Exchange trips by sea vessels and aircraft will be arranged. There will be joint patrol of the international maritime boundaries.
The defence industry cooperation will include joint investment, cooperation in outer-space technology, technical support, exchange of experience, training and maritime infrastructure development.
Annual meetings will be held between the defence secretaries and principal staff officers of the armed forces of the countries to review the defence cooperation. These meeting will be held alternatively in the two countries.
As to why an MoU is being signed rather than a full-blown defence pact, a government official, on condition of anonymity, told Prothom Alo, this is the first time Bangladesh is signing any framework with any country and so due to many considerations, it was decided not to sign an agreement at first. It is simply a matter of caution.

Stephen Hawking appears as hologram

1. Renowned physicist Stephen Hawking has spoken to a Hong Kong audience by hologram, showcasing the growing reach of a technology which is making inroads into politics, entertainment and business.

The British scientist appeared Friday before an audience of hundreds who cheered and snapped pictures with their phones as he discussed his career and answered questions about the possibility of life on other planets, the use of technology in education and the impact of Brexit on Britain.

The 75-year-old said the election of US President Donald Trump was one in a string of “right-wing successes” that would have grave implications for the future of scientific innovation and discovery.
“With Brexit and Trump... we are witnessing a global revolt against experts,” he said, making his first appearance in Hong Kong since 2006.

The swing to the right has come at a time when the world is facing multiple environmental crises, from global warming to deforestation, he added.http://en.prothom-alo.com/science-technology/news/143329/Stephen-Hawking-appears-as-hologram

“The answers to these problems will come from science and technology,” he said.
Hawking suffers from amyotrophic lateral sclerosis (ALS), a form of motor neurone disease that attacks the nerves controlling voluntary movement, leaving him paralysed and able to communicate only via a computer speech synthesiser.

The event was organised by Chinese gaming company NetDragon Websoft, in partnership with ARHT Media, which creates digital human holograms of celebrities including spiritual guru Deepak Chopra, motivational speaker Tony Robbins and slain rapper The Notorious B.I.G..

The technology which allows a human being to appear and interact with audiences in multiple locations simultaneously is gradually expanding its presence.

French far-left candidate Jean-Luc Melenchon appeared to supporters by hologram last month in a technological first for a presidential campaign in France.
