>Pets make great influencers
They have millions of followers on Instagram. They generate major profits for their owners.
They are...pet influencers.
Grumpy Cat, Lil Bub, Boo the Pomeranian and Doug the Pug are just some of the internet's star animals, who do everything from support worthy causes to promote major brands.
Since Instagram launched in 2010, the word "cat" has been used on the platform 193 million times and the word "dog" 243 million times.
"Pets raise endorphins and make people feel happy," animal talent manager Loni Edwards said. "They are adorable to look at and are easier to connect with than human influencers. Human-facing brands want to work with pet influencers because they want to show that they align on the values of their consumer, and their consumer loves pets."
As a result, pet influencers can be incredibly lucrative.
>Pocket money going digital
Children may not be stashing coins in piggy banks for much longer; with the move towards a cashless society, pocket money is moving digital.
To reflect this trend, a flurry of mobile budgeting apps for children has sprung up worldwide: GoHenry, Osper and Gimi to name a few.
These apps offer a simple money management service for children, often for a monthly subscription fee paid by the parents.
Parents can add money to children's accounts, set limits and monitor transactions, while children can choose to save their money or spend it using a prepaid card that works like a debit card.
The apps suggest minimum ages ranging from six to nine for the prepaid card.
The companies behind the apps argue that in an increasingly cashless society, they can be a valuable way of teaching young children about money.
However, some people worry that introducing digital money apps to young children could help to encourage irresponsible spending habits.
>Plants scream when being cut
We always think that it's ok for us to leave our plants unattended during our vacation as we believe that they'll survive just fine.
Plus, plants won't scream like pets, so they must be okay, right?
A recent study done by a group of scientists at the Tel Aviv University has discovered that some plants will scream in a high frequency when they are undergoing stress.
The research was carried out on tomato plants and tobacco plants by cutting their stems and depriving them of water. A microphone is placed 10cm away from the setup.
When they started cutting the stems, they found out that the plants started "screaming" between 20 and 100 kilohertz and they believe that this scream is probably meant to warn other plants and organisms nearby.
The group of scientists said that this changes the way we think of plants as we had always assumed that they are silent, but the thing is their voices are so high-pitched that we just can't hear them.
>Domestic HPV vaccine approved
China has become the third country after the US and the UK to successfully develop and produce the HPV vaccine after the State Food and Drug Administration (SFDA) approved the first application for the registration of a domestic bivalent human papillomavirus vaccine.
The vaccine, priced at 329 yuan per dose, is being prepared for production, with two doses for women aged 9-14 and three for women aged 15-45.
Providing an alternative to foreign drugmakers' products, the newly approved vaccine is designed to protect against Type 16 and Type 18 HPV, the two most common virus strains that lead to cervical cancer.
The new vaccine, known as Cecolin, was jointly developed by INNOVAX, a biotechnology company based in Xiamen, Fujian province, in cooperation with Xiamen University.
Currently, vaccines for HPV are produced by Glaxo-SmithKline, a British pharmaceutical company which makes a two-valent HPV vaccine, and Merck & Co, a US drugmaker which produces four-valent and nine-valent HPV vaccines.
