Chinese scientists discovered a spider species that feeds their babies with milk as mammals, marking the first time humans discovering invertebrates breastfeeding and nursing theirs offspring, said Chinese Academy of Sciences Friday.
Breastfeeding is a unique animal behavior to mammals, including humans. This type of spider, commonly known as big ant spider, discovered with “breastfeeding behavior”, belongs to Myrmarachne of Salticidae, which is a spider species widely distributed in the tropical and subtropical regions of East and Southeast Asia.
“Spider babies which just hatched out clime up on spider moms’ bellies, to eat a kind of liquid (secreted by spider moms), which was tested to be milk containing four times the protein of cow’s milk. We call it spider milk,” said Chen Zhanqi, a post doctor from Chinese Academy of Sciences.
Researchers found after long-term observation that the newly hatched spider babies feed themselves entirely with the milk in the first 20 days after birth, during which they grow as big as half of their mothers. From 20 to 40 days, spider babies go out looking for food by themselves, while also eating milk from their mothers. This period is a transition for weaning.
The study also found that spider babies don’t leave their mothers after weaning, and continue to stay with them in nests, even after they grow up. This kind of spider will take care of its grown-up offspring, which is seen as a long parental behavioral mode. This mode was once thought to only exist in the social vertebrates with long lifespan.
Experts believe that this breakthrough discovery has extremely important significance for the research on revolution of breastfeeding behavior for contemporary animals. — Reuters
Pro-Beijing supporters flooded into a Hong Kong shopping mall waving China flags and singing the Chinese national anthem on Friday (September 13) where they were confronted by with anti-Beijing groups.
The confrontation came hours before a city-wide Mid-Autumn festival celebration where demonstrators are set to carry lanterns and form human chains on the scenic Victoria Peak, an area popular with mainland Chinese tour groups. The human chain is also due to be formed on Lion Rock which separates the New Territories from the Kowloon peninsula.
The anti-China demonstrations started in June in response to a bill that would have allowed people to be sent to mainland China for trial in Communist Party-controlled courts, but have broadened into calls for democracy.
China says Hong Kong is now its internal affair. It denies meddling in Hong Kong and has accused the United States, Britain and others of fomenting the unrest.
Britain says it has a legal responsibility to ensure China abides by its obligations under the Joint Declaration. (REUTERS)
MANILA, Philippines – Nearly P53 million worth of misdeclared agricultural products from China were seized by the Bureau of Customs (BOC) in the Port of Manila.
The BOC said the products that were shipped inside 16 containers arrived in Manila last August 8.
The shipment was consigned to a certain Shinerise Trading Service. It was initially declared as fishballs.
However, upon inspection of the containers, the BOC found that the shipment contains carrots and onions estimated to worth P40.1 million, broccolis worth P10.04 million, and P2.5 million worth of potatoes.
The bureau has issued a warrant of seizure and detention against the said shipment.
The BOC also cancelled the accreditation of the Shinerise Trading Service and its broker was placed under investigation.
The confiscated agriculture products will be destroyed as these did not have necessary clearance as proof that these items are safe for public consumption, the BOC said. RRD (with details from Correspondent Aiko Miguel)
Chinese Premier Li Keqiang told a news conference with visiting German Chancellor Angela Merkel on Friday (September 6) that the Chinese government unswervingly safeguards ‘one country, two systems’ and ‘Hong Kong people govern Hong Kong people’.
Germany’s Chancellor Angela Merkel raised Hong Kong with Chinese premier Li Keqiang in Beijing on Friday, saying a peaceful solution is needed.
Li said Beijing supported the Hong Kong government “to end the violence and chaos in accordance with the law, to return to order, which is to safeguard Hong Kong’s long-term prosperity and stability.”
The extradition bill, which would have allowed people in the former British colony to be sent to mainland China for trial in courts controlled by the Communist Party, triggered mass protests that have since widened into a backlash against the Hong Kong government and its political masters in Beijing.
Hong Kong is bracing for more demonstrations this weekend, with protesters threatening to disrupt transport links to the airport, after embattled leader Carrie Lam’s withdrawal of a controversial extradition bill failed to appease some activists. (REUTERS)
