5 . In times of stress, particularly when the water gets too warm, the coral(珊瑚)erupts the algae(海藻), and the coral turns white, causing a state called coral bleaching(漂白). Just a few degrees of heat can lead to coral bleaching, putting the coral on a path to starvation and death.

Driven by climate change, marine heat waves are becoming one of the greatest threats to the existence of coral, which is important to the ocean ecology. But in some rare good news researchers have discovered coral can recover from bleaching even before a heat wave ends, suggesting it has the potential to survive long heat waves. Coral was thought to survive only if a heat wave lasted just a few weeks.

But no one had studied this process during a longer heat wave. Then in 2015, Julia Baum, a marine ecologist at the University of Victoria, began a survey of two common species: brain and star coral around Kiritimati in the central Pacific Ocean. They checked the condition of the coral as the heat wave struck and disappeared.

Starting in May 2015, the temperature rose about 1 ℃ within 2 months. As expected, coral that housed heat-sensitive algae bleached sooner than those housing the heat-tolerant kind of algae. As the water continued to warm, even heat-tolerant algae erupted.

Many brain and star coral on Kiritimati recovered from bleaching while the water was still unusually warm. Baum said, "The unexpected recovery provides new hope, because it means that even under lasting heat waves, there's a path forward for some of them."

An unusual feature of the recovery is that brain coral that started out with heat-sensitive algae had a higher survival rate(82%)than coral that began with heat-tolerant algae(25%). "That finding is surprising," said Baum, expecting that heat-tolerant algae would be better suited for helping coral survive a heat wave. But during a longer heat wave, it might be more advantageous to start with a heat-sensitive algae.

7 . Children's average daily time spent watching television or using mobile device increased from 53 minutes at 12 months old to more than 150 minutes at 3 years old, according to an analysis by researchers at the National Institutes of Health. Children aged 7 were more likely to spend the highest amount of screen time if they had been in bad home-based childcare or were born to first-time mothers.

“Our results indicate that screen habits begin early,” said Edwina Yeung, an investigator in National Institute of Child Health and Human Development (NICHD), “This finding suggests that interventions to reduce screen time could have a better chance of success if introduced early.”

In the research, mothers of 4,000 children responded to questions on their kids' media habits when they were 12, 18, 24, 30, and 36 months of age.

The American Academy of Pediatrics recommends avoiding digital media exposure for children under 18 months of age, introducing children 18 to 24 months of age to screen media slowly, and limiting screen time to an hour a day for children from 2 to 5 years of age. In the current study, researchers found that 87% of the children had screen time exceeding these recommendations. However, while screen time increased throughout infancy, after 8 years of age, screen time fell to under 1. 5 hours per day. The researchers believe this decrease relates to time consumed by school-related activities.

The study authors classified the children into two groups based on how much their aver- age daily screen time increased from age 1 to age 3. The first group, 73% of the total, had the lower increase, from an average of nearly 51 minutes a day to nearly an hour and 47 minutes a day. The second group, 27% of the total, had the higher increase, from nearly 37 minutes of screen time a day to about 4 hours a day. Higher levels of parental education were associated with the lower odds of inclusion in the second group.

8 . The Indo-Pacific bottlenose dolphins of Shark Bay in Western Australia have an unusual way of obtaining food.

They drive fish into a large, empty marine gastropod shell. Then they carry the shell and captured(捕捉)fish up to the surface, and shake it upside down. Then, the fish go straight down into the dolphins' stomachs. It's called shelling, only the second tool use recorded among dolphins, and the first that dolphins have been seen learning from their friends, just like great apes.

The dolphins were first observed using tools over 20 years ago, slipping sea sponges over their beaks(喙)to protect them as they searched for food. This behaviour is called sponging, and it allows the dolphins to access food in deeper water channels than non-sponging dolphins.

Sponging is a skill passed down from mothers to daughters-a type of learning called vertical transmission. But there is another kind of learning, horizontal social transition, in which individuals pick up skills from their social peers-their friends.

There are similarities between dolphin and great ape societies that have led scientists to believe that dolphins should be capable of horizontal leaning.

Now a team of researchers led by behavioural ecologist Sonja Wild of the University of Konstanz in Germany has finally identified it.

Their data comes from over a decade's worth of observations. Between 2007 and 2018, the researchers documented over 1.000 individual dolphins across nearly 5,300 encounters with the animals.

They used genetic, behavioural and environment data to model the likely transmission pathways, and found that shelling was likely spread among friends, rather than passed down from parents.

This opens the door to a new understanding of how dolphins may be able to behaviourally adapt to changing environments.

In 2011, a large marine heatwave destroyed the seagrass habitat of Shark Bay, in which the dolphins search for food. This resulted in a die-off of both fish and the invertebrates that live in the giant shells that the dolphins use for their fishing, and, afterwards there was an immediate increase in the dolphin's shelling behaviour. It's possible that both the decrease in fish and the increase in shells could have played a role in this uptick.

9 . A four-year-old girl stunned paleontologists after she found a perfectly-preserved dinosaur footprint that dates back 220 million years.

Lily Wilder made the discovery on January 23 while walking along a beach in South Wales with her father and their dog.The family was on their way to the supermarket when Wilder saw the footprint imprinted on a rock.

“It was on a low rock, shoulder height for Lily, and she just spotted it and said, ‘Look, Daddy,’” her mother, Sally Wilder, said.“She is really excited but doesn't quite grasp how amazing it is.”

At first, the family thought the print, which is just over 10 cm (4 inches) long, was scratched out on the rock by an artist.But mother Sally was aware that similar footprints had been found along that piece of the coast before, so she posted about their discovery on social media.“I found this fossil identification page on Facebook and I posted it on there and people went a bit crazy,” she told Wales Online.

Shortly after, the National Museum of Wales got in touch with the Wilder family, and officials have since retrieved the print and put it in the museum.

Experts believe the footprint was most likely left by a dinosaur that stood about 75 centimeters (29.5 inches) tall and 2.5 meters (about 8 feet) long and walked on its two hind feet.It is impossible to identify exactly what type of dinosaur left it, although experts typically classify the print as a Grallator.

Welsh scientists are calling the girl's discovery “the finest impression of a 215 million-year-old dinosaur print found in Britain in a decade,” according to Wales Online.

The family says their daughter's interest in dinosaurs has been inspired since the discovery and that she's been playing with a collection of dino toys and models.“If her name goes down as the finder in the museum, it could be her grandchildren going to visit that in the museum one day, and for years and years and generations to come, which is quite amazing,” mother Sally told Wales Online.
