Topic: Drinking any amount of alcohol causes damage to the brain

There is no such thing as a "safe" level of drinking, with increased consumption of alcohol associated with poorer brain health, according to a new study.


In an observational study, which has not yet been peer-reviewed, researchers from the University of Oxford studied the relationship between the self-reported alcohol intake of some 25,000 people in the UK, and their brain scans.


The researchers noted that drinking had an effect on the brain’s gray matter - regions in the brain that make up "important bits where information is processed," according to lead author Anya Topiwala, a senior clinical researcher at Oxford.


The team also investigated whether certain drinking patterns, beverage types and other health conditions made a difference to the impact of alcohol on brain health.

Topic: Scientists have taught bees to smell the coronavirus 科學家教導蜜蜂嗅出冠狀病毒

Scientists in the Netherlands have trained bees to identify COVID-19 through their sense of smell, according to a press release from Wageningen University.


The research was conducted on more than 150 bees in Wageningen University’s bio-veterinary research laboratory.


The scientists trained the bees by giving them a treat — a sugar-water solution — every time they were exposed to the scent of a mink infected with COVID-19. Each time the bees were exposed to a non-infected sample, they wouldn’t get a reward.


Eventually, the bees could identify an infected sample within a few seconds — and would then stick out their tongues like clockwork to collect the sugar water.


Bees aren’t the first animals to detect COVID-19 by scent. Researchers have also trained dogs to distinguish between positive and negative COVID-19 samples from human saliva or sweat with fairly high levels of accuracy.

Topic: Whale of a time: NYC offers walk-up vaccinations for all

Appointments are no longer mandatory at any of the coronavirus vaccination sites run by New York City, including its newest and maybe coolest location: beneath the giant blue whale at the Museum of Natural History.


Mayor Bill de Blasio announced Friday that the city will now be accepting walk-ins at all its vaccination sites. "You can just walk up and get vaccinated," he said.


The expansion of walk-in service comes as supplies of the vaccine have increased.


Just weeks ago, most people trying to get an appointment for a vaccination in the nation’s biggest city had to game online appointment systems in which scarce slots would be snapped up in moments.

Topic: Serbian diner thanks those getting COVID shots with plates of roast meat (感謝客人打新冠疫苗 塞爾維亞餐館請吃烤肉)

Get a COVID-19 vaccine and you will be served a plate of spit-roast ox or wild game goulash for free - in the Serbian city of Kragujevac.



Restaurateur Stavro Raskovic offered the popular local dishes as his way of promoting vaccination and campaigning for the full reopening of the country’s restaurants, cafes and bars.


Lockdowns in 2020 and partial restrictions this year have driven Biblioteka kod Milutina (Milutin’s Library) restaurant to the brink of closure, he said.


"Our trade, catering, has been particularly hit... and if this (vaccination) is the way out, then we wanted to contribute."


Local health authorities turned the restaurant into a vaccination point to deliver shots made by Pfizer/BioNtech, and China’s Sinopharm.


"Today we have vaccines from both East and West on the menu, to everybody’s taste," said Raskovic.

Topic: Dracula’s castle’ offers tourists Covid shots 「德古拉的城堡」提供觀光客武漢肺炎疫苗接種

Visitors to Romania’s forbidding Bran Castle are being jabbed with needles rather than vampiric fangs this weekend in a coronavirus vaccination drive.


Those who take the jab are handed a certificate hailing their"boldness and responsibility"promising they will be welcome at the castle"for the coming 100 years" - as well as offered a free tour of the"torture chamber".


Nestled in a misty valley in the Carpathian mountains, Bran Castle is associated with the 15th-century Romanian prince Vlad Dracula.


Dracula author Bram Stoker is believed to have been inspired by Vlad and descriptions of Bran Castle when writing his 1897 novel that helped found the modern vampire genre.

德古拉的作者布拉姆.史托克在撰寫他的1897年的小說時,被認為受到弗拉德與布蘭城堡的描述的啟發,這本小說幫助他奠定現代吸血鬼體裁。Source article: https://features.ltn.com.tw/english/article/paper/1449642;https://features.ltn.com.tw/english/article/paper/1449828;https://features.ltn.com.tw/english/article/paper/1450439

Topic: Spanking may affect brain development in children

Spanking may affect a child’s brain development in similar ways to more severe forms of violence, according to a new study led by Harvard researchers.


The research, published recently in the journal Child Development, builds on existing studies that show heightened activity in certain regions of the brains of children who experience abuse in response to threat cues.


The group found that children who had been spanked had a greater neural response in multiple regions of the prefrontal cortex (PFC). These areas of the brain respond to cues in the environment that tend to be consequential, such as a threat, and may affect decision-making and processing of situations.


According to the study’s authors, corporal punishment has been linked to the development of mental health issues, anxiety, depression, behavioral problems, and substance use disorders.

Topic: Coffee before exercise increases fat-burning/運動前喝咖啡增加燃脂

If you’re looking to maximize the amount of fat burned in your next workout, think about having a coffee half an hour before you get started – as a new study suggests it can make a significant difference to fat burning, especially later on in the day.


Researchers found that 3 milligrams of caffeine per kilogram of body weight can boost the rate of fat burning during aerobic exercise, based on results gathered from 15 male volunteers.


The coffee dose was shown to increase maximal fat oxidation rate(MFO, a measure of how efficiently the body burns off fat)by an average of 10.7 percent in the morning and 29 percent in the afternoon.


This is a study with a fairly small sample of participants, so it’s important not to jump to too broad a conclusion, but the results are clear enough to suggest that there is some kind of association there.



Topic: Study Shows Baldness Can Be a Business Advantage 研究:光頭可成職場優勢

Men with shaved heads are perceived to be more masculine, dominant and, in some cases, to have greater leadership potential than those with longer locks or with thinning hair, according to a recent study out of the University of Pennsylvania’s Wharton School.


Some executives say the style makes them appear younger—or at least, makes their age less evident—and gives them more confidence than a comb-over or monk-like pate.


The study found that men with thinning hair were viewed as the least attractive and powerful of the bunch, a finding that tracks with other studies showing that people perceive men with typical male-pattern baldness as older and less attractive. For those men, the solution could be as cheap and simple as a shave.
