IIT Roorkee scientists reveal how this common herb could defeat world's most dangerous superbugs & enhance antibiotic power
superbugs
and improve the effectiveness of antibiotics.
Thymol is a plant-based substance commonly found in thyme. The study suggests it can target
persister cells
, bacteria that survive treatment and cause long-lasting infections, especially in
Acinetobacter baumannii
. This bacterium is known for causing persistent and chronic infections in hospitals.

The findings, published in the Antimicrobial Agents and Chemotherapy journal, also show that thymol may make powerful antibiotics like meropenem work better.
Early results indicate that using thymol alongside meropenem increases the antibiotic's ability to fight infections. This could be a promising way to tackle persistent bacterial infections.
Professor Ranjana Pathania, the lead researcher, said, 'Thymol's ability to break down bacterial persistence and boost existing antibiotics offers a hopeful path to address
antimicrobial resistance
.'

She added, 'By focusing on persister cells, we may improve treatment for chronic and recurring infections.'
The research team discovered that thymol attacks persister cells in several ways. It disrupts the bacteria's energy production, making survival harder. It also damages the bacteria's outer membrane, making them more vulnerable.
Thymol produces reactive oxygen species (ROS) that stress and weaken bacteria. It also blocks bacterial efflux pumps, which can help antibiotics like meropenem work better.
While these findings are encouraging, more research and clinical trials are needed to confirm thymol's use in real medical treatments.
Professor K.K. Pant, Director of IIT Roorkee, said, 'Antimicrobial resistance is a major global problem. This study shows how natural compounds could help overcome persistent infections. It reflects our commitment to research that tackles important health challenges.'
The next stage of research will focus on improving the thymol and meropenem combination and testing its potential through further studies.
If successful in clinical trials, this approach could become a new weapon against antibiotic-resistant infections, the team said.

What is Myasthenia Gravis? Monica Seles opens up after rare disease diagnosis
Monica Seles has opened up about her battle with myasthenia gravis , a rare neuromuscular autoimmune disease that has altered her life to a great extent. The nine-time Grand Slam champion compared the experience of adapting to this 'new normal' to the difficult period she endured after being stabbed by a spectator during a tournament in Hamburg, Germany, in 1993. In a recent interview with The Associated Press, Seles recalled the moment she first noticed symptoms of the disease. While playing tennis with a group of children, she was startled to realise she was seeing two balls coming towards her.

I was like, Yeah, I see two balls.' These are obviously symptoms that you can't ignore," Seles said. "And, for me, this is when this journey started. And it took me quite some time to really absorb it, speak openly about it, because it's a difficult one. It affects my day-to-day life quite a lot." by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Villas For Sale in Dubai Might Surprise You Villas In Dubai | Search Ads Get Rates Undo The 51-year-old Seles, who claimed her first Grand Slam title at just 16 at the 1990 French Open and last competed professionally in 2003, revealed that she was diagnosed with myasthenia gravis three years ago. Speaking publicly about the condition for the first time, Seles chose to share her story ahead of the upcoming US Open, beginning August 24, in hopes of raising awareness about the disease, commonly referred to as MG. Live Events — TennisONEApp (@TennisONEApp) What is Myasthenia Gravis? The National Institute of Neurological Disorders and Stroke describes myasthenia gravis as 'a chronic neuromuscular disease that causes weakness in voluntary muscles, most often affecting young adult women under 40 and older men over 60, though it can appear at any age, even in childhood. The troubling symptoms include weakness in the arm and leg muscles, double vision, fatigue, shortness of breath, difficulty speaking, and swallowing. It has been 30 years since Seles made her emotional return to competition at the 1995 US Open, reaching the final more than two years after she was stabbed by a man during a tournament in Hamburg, Germany. Now, as she faces myasthenia gravis, Seles describes her life as another chapter of adaptation - learning to embrace a 'new normal' and adjust to each challenge as it comes. "I had to, in tennis terms, I guess, reset - hard reset - a few times. I call my first hard reset when I came to the U.S. as a young 13-year-old (from Yugoslavia). Didn't speak the language; left my family. It's a very tough time. Then, obviously, becoming a great player, it's a reset, too, because the fame, money, the attention, changes (everything), and it's hard as a 16-year-old to deal with all that. Then obviously my stabbing - I had to do a huge reset," Seles told news agency AP.

Perseids meteor shower 2025: Regions and US territories that will miss the show and what time is the meteor shower tonight
Every August, stargazers around the world eagerly await the dazzling display of the Perseids meteor shower , a spectacular cosmic light show lighting up the night sky. The Perseids are active from July 17 to August 23, peaking on the night of August 12-13 in the Northern Hemisphere. Originating from debris shed by the comet 109P/Swift-Tuttle, this shower can produce up to 50 to 100 meteors per hour under ideal conditions. But despite its popularity and brightness, not everyone on Earth will get to witness the Perseids this year.

US Territories in the Southern Hemisphere: The only US territories located in the Southern Hemisphere are American Samoa and Jarvis Island. Both of these territories will have little to no visibility of the Perseids meteor shower in 2025, due to their southern locations where the Perseid radiant remains low or below the horizon. Southern Hemisphere: For most of the Southern Hemisphere, including countries like Australia, New Zealand, South Africa, Argentina, Chile, and parts of southern Brazil, the Perseids are either very faint or not visible at all. This is because the radiant never rises high enough above the horizon, and the meteors streak mostly over the northern skies, making sightings very rare or impossible. Equatorial Regions: Near the equator, in countries like Indonesia, Kenya, Colombia, and Ecuador, the Perseids may appear very low on the horizon, making observation challenging. The meteors are fewer and dimmer, often lost to light pollution or atmospheric haze. Areas with Bright Moonlight or Cloudy Skies: Even in the Northern Hemisphere, certain places might have poor viewing conditions due to the bright Waxing Gibbous Moon near the peak dates (which can wash out fainter meteors) or persistent cloud cover. Urban centers with heavy light pollution will also struggle to offer good views. Why some places miss out Radiant location: The Perseids' radiant is in the northern sky, so places in the far south simply don't get to see meteors shoot across the sky. Earth's rotation and orbit: The timing of Earth's position around the Sun means the debris trail of comet Swift-Tuttle is intersected primarily during Northern Hemisphere summer nights. Atmospheric and environmental factors: Cloudy or rainy seasons (like monsoons or austral winter storms), moonlight, and city lights can all obscure the show. Even if you're in a location where the Perseids shower isn't visible, there are other meteor showers throughout the year, some better seen from the Southern Hemisphere, like the Geminids or the Eta Aquariids. Live Events What time is the meteor shower tonight The Perseids meteor shower in 2025 will be active from July 17 to August 24, with the peak night being August 12-13. Peak activity usually happens in the pre-dawn hours, roughly between 2:00 AM and 5:00 AM local time, when the radiant is highest in the sky. Meteors can sometimes be seen as early as 10:00 PM the night before the peak, but rates will be lower.

Wolbachia transinfection: China's plan to mate lab mosquitoes with wild ones to tackle chikungunya
The Chinese government has taken prevention and control measures to try to curb the spread of chikungunya, a virus that often causes fever and joint pain. The steps initiated by the communist regime have caused concerns among medical professionals and the people. As the chikungunya outbreak continues to engulf China, Guangdong Province reported 1,387 new chikungunya cases between August 3 and August 9, 2025, The EPOCH Times reported, citing a notice by the provincial Centers for Disease Control and Prevention (CDC). According to state media, the cumulative number of chikungunya cases as of July 29 in Foshan, Guangdong, where the first cases of the outbreak were reported on July 8, had crossed the 6,000 mark. The measures taken by the Chinese authorities amid the chikungunya outbreak include mandatory blood tests and mosquito breeding .

It is different from the saliva tests for COVID-19. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like The Simple Morning Habit for a Flatter Belly After 50! Lulutox Undo China's largest mosquito breeding facility in the Huangpu District of Guangzhou city, Wolbaki, was running at full capacity and releasing 5 million specially treated male mosquitoes per week, The EPOCH TIMES reported, citing Chinese state media. The step was taken in the hopes of them mating with the wild female mosquito population to produce unviable eggs in a population control technique known as Wolbachia transinfection , where the reproductive compatibility of male mosquitoes is altered by an infection with the common naturally occurring Wolbachia bacterium. Unviable eggs are eggs that, for various reasons, cannot develop into viable offspring. Live Events What is Wolbachia transinfection? Wolbachia transinfection is a method where the reproductive compatibility of male mosquitoes is altered by an infection with the common naturally occurring Wolbachia bacterium. 'When the [infected] male mosquitoes carrying the Wolbachia bacterium mate with wild female mosquitoes that do not carry the bacteria, the eggs produced cannot develop normally due to cytoplasmic incompatibility and cannot hatch into mosquito larvae,' Gong Juntao, the head researcher at Guangdong's Wolbaki company that produces the mosquitoes, told Chinese media, as quoted by THE EPOCH TIMES. Wolbachia transinfection has loopholes The method has loopholes. For instance, if infected lab females are not separated and instead released into the wild, they can continue to successfully breed and spread disease. What is chikungunya? Chikungunya is a disease caused by a virus of the same name. The chikungunya virus was first identified in people sickened during an outbreak in Tanzania in 1952. Its name is derived from a word in the Makonde language, which means 'that which bends up,' due to the severe pain it can cause. Chikungunya is transmitted by infected mosquitoes and mostly causes mild symptoms. The majority of people who get chikungunya recover without needing medical attention after one to two weeks. What are the symptoms of chikungunya? Chikungunya typically produces symptoms including fever, muscle pain, nausea, fatigue, and a rash. But in rare cases, it can cause debilitating joint pain that persists for months or even years. Patients who get severely ill often require hospitalization because of the risk of organ damage. The World Health Organization says severe cases and deaths are rare and mostly occur in babies or elderly people with underlying health conditions. Is there a treatment or vaccine? There is no specific treatment for chikungunya, but health workers can treat the symptoms by giving medicines to lower fevers or ease muscle pain. Two vaccines have been approved in several regions, including Britain, Brazil, Canada, and Europe. Those are mostly targeted at travelers and are not widely available in the countries most affected by chikungunya.
