3 . A group of researchers studying the behavior of Amur tigers, also known as Siberian tigers, have found that they have different “personality” types that help them survive and raise their baby tigers.
According to the previous investigation, Amur tigers are definitely the largest cuts in the world. They live in vast forests in wildness areas of eastern Russia and in protected areas of northern China. There are about 400 of these tigers left in the wild, although there are probably hundreds more living in zoos or reserves.
The researchers based the study on a human test called “The Big Five”, which scores people on five personality features. They asked feeders working with 248 cats in two shelters to spy on the tigers and give an account of their personalities. The results divided the tigers into two groups, which the researchers described as having either “majesty” or “steadiness”. Tigers in the majesty category were those that appeared “dignified (高贵的) and ambitious”. The tigers in the steadiness category were “sincere and tolerant”.
Majestic tigers had a higher social status, spent more time hunting live animals, and mated and ate more. The steady tigers seemed gentler and loving toward one another. Rosalind Arden, co-author of the study, said, “It’s pleasant to see that you don’t have to be dominant, fierce, competitive, and aggressive in order to succeed as a tiger, which doesn’t correspond with people’s traditional insights into tigers.”
There were female and male tigers in both categories. In fact, female Amur tigers are rare and feel exhausted after giving birth to baby tigers so that fathers often help raise the baby tigers. Having a steady personality, especially for male ones, could play a significant role in the relatively long amount of time — two to three years — that baby tigers stay with their parents. The researchers say both personalities have advantages that help the tigers survive threats, including loss of habitat and hunting. The team hopes the study will encourage more support from all walks of life in a bid to guarantee the tigers’ conservation.

4 . A new project in the Caribbean is setting out to save coral reefs(珊瑚礁)- and the world. The Ocean-Shot Project, spearheaded by climate scientist Dr. Deborah Brosnan, launched in 2021 to develop a “massive, first-of-its-kind” coral reef restoration initiative in the Caribbean country Antigua and Barbuda.
“We lose more coral reefs in a day that we can restore in a decade,”Brosnan said. “Our progress towards protecting coral reefs——which ultimately protect us——is too slow. So Ocean- Shot Project is about literally rebuilding the reefs, the architecture of the reefs, for the future. ”
What sets this project apart from other coral reef restoration projects is its focus——the architecture of the reef itself. While many initiatives prioritize saving the corals, Ocean-Shot Project tacks on the additional focus of developing the base for those corals to grow and thrive.
“Coral secretes(分泌) calcium carbonate, creating a sort-of concrete around itself that becomes the structure for the reef. But that process can take hundreds and thousands of years,”Brosnan said. And with coral bleaching(白化) events only predicted to become more intense in the coming decades as global and ocean temperatures warm, this can be a problem for reefs that need to be able to recover.
“What we’re doing is we’re saying, ‘let’s learn from the corals, let’s learn from nature,’”Brosnan said. “And let’s make this happen quickly.”
To make that happen, her team is creating reef structures in a lab and then planting them in the ocean, a process that Brosnan likened to“gardening”. The team is also planting“resilient corals”among the structures that have already survived several bleaching events. Previously, her team deployed their first set of these structures, called modules, into the ocean around Antigua and Barbuda. And it’s already seeing significant success.
“We saw a whole ecosystem start to recognize these reefs as home and just move right on in. So what it told us is that if we provide the living structure, the ecosystem will respond in return,”Brosnan said.

5 . Using first-of-their-kind observations from the James Webb Space Telescope. a University of Minnesota Twin Cities-led team looked more than 13 billion years into the past to discover a unique, minuscule galaxy cluster (星系团) that generated new stars at an extremely high rate for its size. The galaxy is one of the smallest ever discovered at this distance —around 500 million years after the Big Bang — and could help astronomers learn more about galaxies that were present shortly after the universe came into existence.
The James Webb Space Telescope can observe a wide enough field to image an entire galaxy cluster at once. The researchers were able to find and study this new, tiny galaxy because of a phenomenon called gravitational lensing (引力透镜), where mass, such as that in a galaxy or galaxy cluster, bends and magnifies (放大) light. A galaxy cluster lens caused this small background galaxy to appear 20 times brighter than it would if the cluster were not magnifying its light.
The researchers then measured how far away the galaxy was, in addition to some of its physical and chemical properties. Studying galaxies that were present when the universe was this much younger can help scientists get closer to answering a huge question in astronomy about how the universe became reionized (再电离的).
“The galaxies that existed when the universe was in its primary stage are very different from what we see in the nearby universe now,” explained Hayley Williams, first author on the paper and a PhD student at the Minnesota Institute for Astrophysics. “This discovery can help us learn more about the characteristics of those first galaxies, how they differ from nearby galaxies, and how the earlier galaxies formed.”
“The James Webb Space Telesco pe can collect about 10 times as much light as the Hubble Space Telescope and is much more sensitive at redder, longer wavelengths. This allows scientists to access an entirely new window of data,” the researchers said.

6 . Certain stem cells have a unique ability to move between growth compartments(隔间) in hair follicles(毛囊), but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.
Led by researchers from NYU Grossman School of Medicine, the new work focused on cells in the skin of mice and also found in humans called melanocyte stem cells, or McSCs. Hair color is controlled by whether nonfunctional but continually multiplying pools of McSCs within hair follicles get the signal to become mature cells that make the protein pigment(色素) responsible for color.
The new study showed that McSCs are remarkably plastic. This means that during normal hair growth, such cells continually move back and forth between maturity and immaturity as they move between compartments of the developing hair follicle. It is inside these compartments that McSCs are exposed to different levels of maturity-influencing protein signals.
The researchers found that as hair ages, comes off, and then repeatedly grows back, increasing numbers of McSCs get stuck in the stem cell compartment. They remain there, do not mature into the transit-amplifying state, and do not travel back to their original location in the germ compartment, where they regenerate into pigment cells.
Specifically, the research team found that McSCs transform between their most primitive stem cell state and the next stage of their maturation, depending on their location.
“Our study adds to our basic understanding of how McSCs work to color hair,”said study lead investigator Qi Sun, PhD, a postdoctoral fellow at NYU Langone Health. “The newfound mechanisms raise the possibility that the same fixed-positioning of McSCs may exist in humans. If so, it presents a potential pathway for changing over or preventing the graying of human hair by helping jammed cells to move again between developing hair follicle compartments.”

8 . Some ways to budget for the best summer
Budgeting can be challenging, particularly when there are a lot of additional bills and expenses that need to be paid every month.
Set a budget
Setting a budget and ensuring that you stick to it is crucial.
If you end up with a collection of lp’s, 2p’s and 5p’s, you can begin placing these in individual pots either in the kitchen or the living room area. This is ideal for savings as you can then cash these in to earn an extra £5-£10. This is beneficial for you as this can then be used to contribute towards spending money or other elements.
Sell items you no longer want
Open a savings account
The final way for you to begin saving money is to open a savings account. Every time you get paid, you can then set up an automated payment into a savings account to help you save money immediately.
| A．Save all loose change |
| B．Cut expenses you no longer use |
| C．This is the first way to ensure that you are not overspending |
| D．If you are someone who loves to have an annual spring clean |
| E．Though it can take time to generate the funds for a large holiday |
| F．However, it is not impossible and all it takes is a few simple changes |
| G．This will ensure that you have enough to pay the bills as well as begin saving |
A lot of people look forward to retirement after decades of working. But on the other hand, there are others who are still so passionate about their field——it’s difficult for them to hang up their hats.
Depending on the career, it could be possible to continue working if one really wants to. That is unless health issues arise and leave the person no choice but to walk away.
Sadly, this is what happened to a man named Harold. Unfortunately, he found himself no longer able to work as a crane (起重机) operator because of his health. He felt lonely because his children didn’t visit him much.
Thanks to the kindness of a stranger, Harold was able to relive his days of working on the job site.
It all started when crane operator Shawn Beveridge of Ohio kept noticing a man in a wheelchair sitting outside of a nursing home. Day after day, the man would sit there watching the job site and the cranes move about for hours.
Shawn was confused why the elderly gentleman showed up every day, and finally became curious enough to introduce himself.
“Since day one when I arrived on this job site, I’ve noticed him sitting there every morning from 7 am, he takes lunch when we do and doesn’t leave until I shut the crane down and head out.” Shawn wrote in his blog. “I originally had thought to myself, ‘He’s just a curious old man and wanting to enjoy his days outside VS being cooped up in his room.’Well after a couple of days. I myself got curious, so I walked over and introduced myself to him.”
Shawn learned that the man’s name was Harold and the two ended up conversing for about two and a half hours.
