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
MANILA, Philippines — President Rodrigo Duterte maintained that he will raise the arbitral ruling that favors the Philippines in the disputed territories in the West Philippine Sea when he visits China next week.
Duterte is scheduled to fly to China for a working visit from August 28 to September 3.
He will meet Chinese president Xi Jinping and talk about the Hague ruling, the code of conduct, as well as the proposed joint oil exploration in the West Philippine Sea.
“So whether you like it or not, would it make you happy or not, angry or otherwise. Sorry, but we have to talk the arbitral ruling, then what we get, if there is a start of the exploration and extraction of whatever there is in the bowels of the earth,” the President said during the inauguration of the 7.5 megawatt peak solar power project in the municipality of Odiongan, Tablas Island in Romblon on Wednesday (August 21).
“The proposal of 60-40 in our favor, would be a good start. I hope it would graduate to something like towards how do we solve the arbitral ruling peacefully,” he added.
The event was the President’s first public engagement after being out of the public eye for more than a week. – MNP (with details from Rosalie Coz)
A Chinese national working at Britain’s Hong Kong consulate has been detained in China’s border city of Shenzhen for violating the law, the Chinese foreign ministry said on Wednesday (August 21), likely worsening already strained ties between Beijing and London.
Simon Cheng did not return to work on Aug. 9 after visiting the neighbouring mainland city of Shenzhen the previous day, Hong Kong news website HK01 reported.
Cheng’s family confirmed his disappearance in a Facebook post on Tuesday (August 20) night, saying he travelled from Hong Kong to Shenzhen on the morning of Aug. 8 for a business trip.
Speaking at a daily news briefing in Beijing, Chinese foreign ministry spokesman Geng Shuang said Cheng had been detained for 15 days by Shenzhen police for violating public security management regulations, though he gave no details.
“He is not a UK citizen. In other words that means he’s Chinese, so it’s entirely an internal matter for China,” Geng said.
“We’ve made stern representations to Britain for the series of comments and actions they’ve made on Hong Kong,” he added.
Britain has said it is “extremely concerned” by reports that the staff member at the consulate in its former colony had been detained.
Hong Kong has been gripped by anti-government protests in recent weeks, with Beijing accusing Britain and other Western countries of meddling in its affairs. (Reuters)
