What makes someone ‘cool’? Study finds six traits that transcend age, gender, and culture

Click here for more articles by Kormedi.com If you've ever wondered what it takes to be considered “cool,” science now has an answer — and it seems to apply across the world. A global study published under the title “Cool People” in the Journal of Experimental Psychology identified six personality traits that define a “cool” person, regardless of nationality, age, or gender. Researchers surveyed 5,943 participants in 12 countries, including Korea, the United States, China, Germany, Mexico, Nigeria, and more. Participants were asked to reflect on what makes a person “cool” and what makes someone “good,” and then rated both types of individuals using personality and value-based assessment tools. Only people who already understood the meaning of the term “cool” were included in the analysis. The study found that people widely associate coolness with the following six traits: extroversion, hedonism, power, adventurousness, openness and autonomy. These traits appeared consistently, regardless of the participants’ country, age, gender, or education level, suggesting

Can finger length predict sexual desire? What your index and ring fingers might reveal

Click here for more articles by Kormedi.com A new study suggests that the length ratio between your index and ring fingers could be linked to sexual behavior and preferences — even in animals. According to research published in the journal Experimental Animals, scientists from Okayama University in Japan found that a simple measurement known as the 2D:4D ratio — the length of the second digit (index finger) divided by the length of the fourth digit (ring finger) — may serve as a biological marker for predicting sexual activity. The team conducted mating experiments with male mice. Those that ejaculated upon first encounter had shorter index toes than those that didn’t. These mice also exhibited greater sexual desire: they ejaculated more frequently, more quickly, and showed stronger erectile function. Lead researcher Professor Hirotaka Sakamoto said it was discovered prior to this experiment that the 2D:4D ratio could serve as a reliable biological indicator of sexual activity in mice, adding that mice with shorter second digits were not only more sexually active, but also showed

Heatstroke first aid tips as Korea battles extreme heat

An unprecedented heat wave this July is putting the health of many in Korea at serious risk. On Tuesday, Seoul recorded a high of 37.7 degrees Celsius — the hottest temperature ever recorded in early July since official records began. The Korea Disease Control and Prevention Agency (KDCA) said Tuesday that more than 1,200 cases of heat-related illnesses have been reported so far this year — more than double the number recorded by this time last year. Eight people have already died from heatstroke. Medical professionals warn that extreme heat can lead to heatstroke, a life-threatening condition in which the body loses its ability to regulate its temperature. Heatstroke can also cause severe complications such as multiple organ damage and dysfunction and carries a high fatality rate. “Heatstroke that leads to loss of consciousness occurs when the autonomic nervous system fails and the body can no longer regulate its temperature,” said Lee Sung-woo, an emergency medicine specialist at Korea University Anam Hospital in Seoul. In addition to heatstroke, prolonged exposure to extreme h

40% of elderly disabled Koreans live alone: report

A new report reveals that nearly 4 in 10 Koreans aged 65 or older with disabilities live alone, facing a risk of social isolation 1.7 times higher than their non-disabled peers. According to a report released Wednesday by the Korea Disabled People’s Development Institute (KODDI), a state-run research center, 39.4 percent of people with disabilities in that age bracket live alone, compared to 32.5 percent among non-disabled seniors. The analysis found that 26.3 percent of older adults with disabilities are considered socially isolated — defined as having no one to turn to when feeling depressed or needing help with daily tasks — compared with 15.5 percent of their non-disabled counterparts. As of 2024, there were 1,455,782 registered disabled people aged 65 or older, according to Ministry of Health and Welfare data. This figure accounts for 14.6 percent of all seniors in Korea. In addition to facing a higher risk of isolation and related mental health issues, many elderly people with disabilities also struggle financially. The average monthly household income for elderly disabled peo

Morning apples are gold, but are evening apples poison? Here’s what experts say

Click here for more articles by Kormedi.com An old saying goes, “An apple in the morning is gold; in the evening, poison.” But how much truth is there to this idea? Apples, rich in antioxidants, remain a staple in many breakfast routines, even as rising prices deter some consumers. As people with high blood sugar or prediabetes wonder whether they can safely eat the sweet fruit, experts say the key lies in quantity and form. Can people with high blood sugar eat apples? According to the Korea Disease Control and Prevention Agency and the Korean Diabetes Association, even people with diabetes can eat apples — within limits. Fruits are high in carbohydrates and sugar, which can raise blood glucose levels if overconsumed. A proper serving size for someone managing blood sugar is about one-third of a medium apple (100 grams), which corresponds to one standard exchange unit. For comparison, half a melon or orange (100 grams), a large wedge of watermelon (250 grams), a quarter of a pear, 10 strawberries, or one large tomato (350 grams) are also considered one serving. If a person has alre

S. Korea unveils world’s 1st recombinant anthrax vaccine

HWASUN, South Jeolla Province — Two men, clad head to toe in protective gear, examine a monitor as they converse. On the screen is a fermentor holding 400 liters of a genetically transformed strain, engineered to express the antigen that triggers immunity against anthrax. Welcome to GC Biopharma Corp's Hwasun plant, home to the world’s first facility dedicated to producing Barythrax — the first anthrax vaccine developed using recombinant protein technology. Created in collaboration with the Korea Disease Control and Prevention Agency (KDCA), the vaccine is the culmination of 28 years of relentless research and development. Approved by the Ministry of Food and Drug Safety in April, Barythrax significantly reduces toxin-related side effects compared to earlier versions. Anthrax, most notably used in the 2001 bioterror attacks — when spores were sent through mail in the United States, leading to five deaths — is regarded as one of the most dangerous potential biological weapons due to its lethal properties. Its spores can survive for decades, even in harsh environments. While leth

Think alcohol-free beer is safe? Doctors warn it may still trigger gout

A cold beer on a hot summer day may be a simple pleasure for many, but for others, it can trigger debilitating pain. With people in their 20s to 40s making up nearly half (48 percent) of all gout patients, young adults are increasingly being warned to take precautions. Gout is an inflammatory joint disease caused by the buildup of uric acid crystals in cooler parts of the body, like the toes. When the body’s white blood cells recognize these crystals as foreign invaders, they trigger an immune response. The resulting inflammation irritates the nerves and leads to gout attacks, often felt as sudden pain in the big toe, ankle or knee. “Gout used to be considered a typical middle-aged men’s disease, but due to modern lifestyle factors such as unbalanced diets and drinking alcohol before or after workouts, we’re seeing a noticeable rise among younger adults,” said Hwang Ji-won, a rheumatologist at Kyung Hee University Hospital. Summer poses an even higher risk for gout flare-ups. Hot weather increases sweating, leading to rapid fluid loss and a rise in blood uric acid concentratio

Number of heat-related patients jumps over 70 percent: How to stay safe during extreme heat

With heat wave advisories issued across South Korea — from Seoul on Monday to other regions like Incheon, Suwon, Gangwon and South Chungcheong by Wednesday — oppressive heat and humidity continue to grip the country. Such weather puts added stress on the body’s ability to regulate its temperature, raising the risk of heat-related illnesses including heat exhaustion, heat cramps and heatstroke. Experts advise checking the weather forecast before any outdoor activity, and staying indoors on days with heat wave alerts. Drinking plenty of water and wearing lightweight, breathable clothing can also help prevent heat-related conditions. According to the Health Insurance Review and Assessment Service, 27,248 patients were treated for heat-related illnesses in 2024 — up about 74 percent from 15,638 cases in 2022. These conditions, triggered by prolonged exposure to high temperatures, include heat exhaustion, heat cramps and the more dangerous heatstroke. Heatstroke is a medical emergency caused by the failure of the hypothalamus — the brain’s temperature regulation center. Symptoms
