Chinese scientists first discover spider species breastfeeding, nursing

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

The country experienced a total of 13 hours of daylight hours due to the summer solstice.

According to the Space, Science, and Astronomy Section of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) Chief Dario Dela Cruz, the summer solstice is when the sun reaches the northernmost point in Earth’s sky.

“Ang summer solstice ibig sabihin kasi nito ang araw kasi ay nagmo-move ng 23.5 degrees papuntang North and then 23 degrees papuntang South, (The summer solstice is when the sun is moving 23.5 towards North and then 23 degrees towards South)” he said.

The sun had set around 6:27 p.m. Areas like Basco, Batanes and Baguio had around 13 daylight hours. Areas in Metro Manila also experienced more than 12 daylight hours.

The summer solstice also marks the end of a season. It marks the change from spring to summer season in the Northern Hemisphere and the change from summer to fall season in the Southern Hemisphere.

Meanwhile, winter solstice will be experienced around December when the country will experience the longest night.

According to PAGASA’s Space, Science, and Astronomy Section, there is no need to be alarmed because a solstice is a natural occurrence.AAC (with reports from Aiko Miguel)

China’s President Xi Jinping held talks with North Korean leader Kim Jong Un in Pyongyang as part of his two-day state visit.

They discussed the ‘new era’ of relations between the two countries, as they mark the 70th anniversary since the establishment of diplomatic ties.

Chinese President Xi Jinping arrived in North Korea on Thursday (June 20) as Beijing looks to bolster its neighbor, hit by U.N. sanctions over its nuclear and missile programs, a week before Xi and U.S. President Donald Trump meet amid a bitter trade dispute.

Xi, whose entourage includes the head of China’s state economic planner, will be in reclusive North Korea for two days, becoming the first Chinese leader to visit in 14 years, and could bring fresh support measures for its floundering, sanctions-bound economy.

China is the North’s only major ally and the visit comes amid renewed tension on the Korean peninsula as the United States seeks to persuade Pyongyang to give up its nuclear weapons. (REUTERS)

Makabayan bloc believes that the boat captain of the sunken fishing vessel was pressured to change statements after their meeting with Department of Agriculture (DA) Secretary Manny Piñol.

Bayan Muna Partylist Representative Carlos Zarate said the fishermen might have been intimidated or bribed in order to change their statements about the incident.

“There was really a pressure. They are bombarded by so much misinformation. Itinu-twist ang kanilang statement siguro may mga pagbabanta pa and offer of parang bina-bribe bigyan ng mga ganitong bangka etc. but it will not erase the fact, (They twist [the fishermen’s] statement maybe there are even threats and bribes. They may have bribed them with these kinds of boats etc.),” he said.

Outgoing Magdalo Representative Gary Alejano said the Reed Bank fishermen are facing a lot of pressure.

The group Pambansang Lakas ng Kilusang Mamamalakaya ng Pilipinas (PAMALAKAYA-Pilipinas) called for transparency on the closed-door meeting with Agriculture Secretary Manny Piñol.

“We demand an explanation and transparency from Piñol on what actually happened inside that house that led to the complete turnaround on the position of the boat captain on the incident that happened on the night of June 9,” their statement reads.

In a radio interview, Secretary Piñol denied there was any intimidation during the meeting. He said his actions are only brought by good intentions.

Meanwhile, Occidental Mindoro Representative Josephine Sato said there should be a ‘marine inquiry’ on the incident.

“Kami po ay humihiling, sa lalong madaling panahon, na magkaroon ng marine inquiry, (We wish to have a marine inquiry as soon as possible)” she said.
