>Tesla inks deal with CATL
US electric carmaker Tesla announced a partnership with CATL, China's largest power battery producer, prompting insiders to call the deal a win-win situation.
According to Tesla, CATL has become its third power battery supplier, following Japanese power battery manufacturer Panasonic and South Korean battery marker LG Chem.
Joining hands with China's leading battery maker was Tesla's response to a large demand for power batteries in developing the Chinese market, according to auto portal Gasgoo.
With the establishment of its gigafactory in Shanghai and the delivery of its China-made Model 3 vehicles, Tesla is working to expand its battery supply, in a bid to reduce trade risks and improve the company's bargaining power.
>Headphones purify air
Dyson's plans for an air purifier that could double as a pair of headphones have been published by the UK patent office, at a time when face masks have become must-have accessories to fight the spread of a deadly virus across Asia.
The product, developed by Dyson Ltd engineers, houses a filter within the headphones, with a form of nozzle providing filtered air to the user.
The patent notes that "air pollution is an increasing problem and a variety of air pollutants have known or suspected harmful effects on human health."
Dyson is best known for its vacuum cleaners and hand dryers.
Any bid to grow in the headphone market would mark a leap for Dyson, pitting it against Apple Inc's AirPods and Beats and high-end gadgets from the likes of Bose and Sennheiser, according to insiders.
However, the potential to market a wearable purifier to consumers in Chinese cities could be a major driver for the project.
>Low self-esteem causes depression
Low self-esteem makes us feel bad about ourselves. Over time it also can cause the development of serious mental conditions such as depression.
Clinicians use low self-esteem as one possible symptom when they diagnose the psychiatric condition of major depressive disorder.
A person with low self-esteem takes things personally, and in a negative way.
People with low self-esteem try not to disprove but to verify their negative self-concept by seeking negative feedback from the people in their network.
They think about their inadequacies, focus on the negative feedback they receive from others, and as a result become more depressed.
Their negative mood also leads them to be perceived more negatively by others, which leads them to feel hurt and rejected.
Low self-esteem is a risk factor for depression, regardless of who is tested and how.
Therefore, if a person has low self-esteem, there's an increased risk of developing depression.
This is a very important discovery because it shows that improving a person's self-esteem can make him or her feel better.
