Researchers from Tsinghua University analyzed survey results of 1,028 Chinese men with an average age of 27.8.

About 57.6 percent of the participants had MPHL, or male pattern hair loss.

Among the participants, 44.6 percent said they drank sugar-sweetened drinks more than seven times a week.

The researchers found that those with a higher consumption level of sugar-sweetened beverages also had a greater risk of male-patterned hair loss.

The sugar-sweetened drinks included in the survey were juices, soft drinks, sports and energy drinks, sugary milks, nut milks, sugary teas and tea drinks, and coffee.

The researchers said that higher amounts of sugar can lead to higher serum glucose concentrations, creating an overactive polyol pathway.

This pathway is known as a place where glucose is converted to fructose.

The study states that hair loss symptoms suggest an "overactive polyol pathway."

When the pathway is too active, it may lead to diabetes.

> Study links lifestyle to rate of memory decline


Memory loss is a common part of aging.

A decade-long study of older adults in China has found that a healthy lifestyle is linked to slower memory decline even when people carry a risky gene for Alzheimer's.

Researchers from China's National Center for Neurological Disorders and other medical institutes followed 29,000 people aged at least 60 years with normal cognitive abilities for up to 10 years. Forty-nine percent of the participants were women.

At the beginning of the study in 2009, the researchers tested the participants' memory function with the Auditory Verbal Learning Test.

They were also tested for the APOE gene, the most common gene linked with Alzheimer's. Around 20 percent of the participants were carriers of the risk gene.
同时,他们还对研究对象体内最常见的与阿尔茨海默病有关的载脂蛋白E(apolipoprotein E, APOE)基因进行了检验,发现其中20%是携带者。

The participants received assessments in 2012, 2014, 2016 and 2019.

In the follow-ups, six healthy lifestyle factors were analyzed: a healthy diet (adherence to recommended food items), regular physical exercise (at least 150 minutes of moderate intensity or 75 minutes of vigorous-intensity exercises per week), active social contact (for example, seeing friends and family at least twice a week), active cognitive activity (for example, reading, writing, playing chess at least twice a week), non-smoking and never drinking alcohol.

The results showed that the mean AVLT scores continuously declined over the 10 years.

The highest test scores were in the favorable group and the lowest in the unfavorable group.

The participants with favorable and average lifestyles, even when they were APOE carriers, had a slower rate of memory decline than the participants with unfavorable lifestyles.

Meanwhile, the results also showed that a favorable lifestyle was associated with a 90 percent lower probability of progression to mild cognitive impairment and dementia. The number for the average group was 30 percent.

The researchers said that they studied the contribution of each lifestyle factor and their combined effects in a large sample size over an entire decade and offered important information to protect older adults against memory decline.

The results about the APOE carriers also provide an optimistic outlook that healthy lifestyle risks are associated with a slower rate of memory decline, regardless of the genetic risk.

> King will not be featured on new Australian banknote

Australia will replace the portrait of British monarch on its $5 banknote with a new design to reflect the history of its indigenous culture, the country's central bank said on Thursday.

The $5 bill was Australia’s only remaining bank note to still feature an image of the monarch, which currently is the late Queen Elizabeth II.

The decision announced by the central bank means that Charles III will not be featured on Australia's new five dollar note.

Like many former British colonies, Australia is debating to what extent it should retain its constitutional ties to Britain.

According to the announcement, the change is supported by the Australian Government, and followed by consultation with First Australians in designing the $5 banknote.

Jim Chalmers, the RBA's treasurer, said: “The monarch will still be on the coins, but the $5 note will say more about our history and our heritage and our country, and I see that as a good thing.”
