London (AFP) — A dinosaur dubbed one of the “strangest” ever boasted an elaborate armoury of long bony spikes and a tail weapon, according to findings published in the science journal Nature.


Spicomellus, which roamed the earth 165 million years ago, is the world’s oldest ankylosaur, a herbivorous group of dinosaurs known for their tank-like bodies.


Palaeontologists’ image of Spicomellus was based on a single rib bone found in Morocco in 2019.

But newly discovered remains have helped scientists form a clearer picture of the unusual dinosaur.

The fossils showed it had bony spikes fused onto all of its ribs — something never seen before in any other vertebrate species living or extinct, according to the research published Wednesday.

Richard Butler, a professor at the University of Birmingham and the project co-lead, called the fossils an “incredibly significant discovery”.

“Spicomellus is one of the strangest dinosaurs that we’ve ever discovered,” he said.

Professor Susannah Maidment of London’s Natural History Museum said the armour evolved initially for defence purposes but was probably used later to attract mates and show off to rivals.

“Spicomellus had a diversity of plates and spikes extending from all over its body, including metre-long neck spikes, huge upwards-projecting spikes over the hips, and a whole range of long, blade-like spikes, pieces of armour made up of two long spikes, and plates down the shoulder,” she said.

“We’ve never seen anything like this in any animal before.”

NEW YORK — About 780,000 pressure washers sold at retailers like Home Depot are being recalled across the U.S. and Canada, due to a projectile hazard that has resulted in fractures and other injuries among some consumers.


According to a Thursday recall notice published by the U.S. Consumer Product Safety Commission, TTI Outdoor Power Equipment is recalling certain models of its Ryobi-branded electric pressure washers because the products’ capacitor can overheat and burst, “causing parts to be forcefully ejected.”


That poses serious impact risks to users or bystanders. To date, the CPSC notes, the power tool and equipment company has received 135 reports of capacitors overheating in the U.S. — including 41 reports of explosions that resulted in 32 injuries and/or fractures to consumers’ fingers, hands, face and eyes. A corresponding notice from Health Canada noted that no additional incidents were reported in Canada.


Consumers in possession of the now-recalled pressure washers are urged to stop using them immediately and visit Ryobi’s recall website to learn about how to receive a free repair kit, which includes a replacement capacitor.

The Ryobi washers under recall have model numbers RY142300 and RY142711VNM. About 764,000 were sold in the U.S., in addition to 16,000 in Canada.

In the U.S. these products were sold at Home Depot and Direct Tools Factory Outlet between July 2017 and June 2024, the CPSC notes, for about $300 to $400 in stores and online.

TTI Outdoor Power Equipment is a subsidary of Techtronic Industries (TTI). The Associated Press reached out to the company for further comments on Thursday.

Beyond Thursday’s pressure washer recall, TTI also recalled Ryobi-branded mowers and hedge trimmers earlier this year — due to fire and laceration hazards, respectively.

GTA high schooler comes up with early Parkinson's detector

He’s only be 16, but Richmond Hill high school student Matthew Shen, who lives in Vaughan, has come up with an AI-driven diagnostic tool to detect early stage Parkinson’s disease using a three-second recording of a person’s voice.


Shen said he was inspired by a friend’s grandmother who was diagnosed with it in hospital when he was seven.


“I saw her struggling to speak with a speech therapist,” he said. “It was really impactful because Joseph’s grandmother tutored me for math. She played board games with me. And now watching her struggling to speak just kind of really pushed me to do this work.”

His research has already been published in the academic journal Nature Scientific Reports this past April, and he delivered a TEDX talk at Western University in February.

“I started this project in February 2024,” said Shen, who is a student at St. Theresa of Lisieux Catholic High School.

“Initially, it was just for the purpose of publishing the paper but then as the school year (for Grade 11) rolled around, I realized I wanted to compete in science fairs and I used this project to do that,” he said.


Shen’s diagnostic tool, for which he spent over 1,000 hours working on, was offered to the York Region Science and Technology Fair in April, for which he was recognized with a gold medal, qualifying him for the 2025 Canada-Wide Science Fair, for which he won the silver medal and the Youth Can Innovate Award worth $8,000.

He gave half of the money to his high school’s science department and half to the regional science fair.

“Basically, the way it works is that in the user interface people input their voice and from that AI tool will extract vocal bio-markers,” Shen said.

“For example, deviations in your pitch or changes in your amplitude within your voice. With Parkinson’s disease, people have shaky hands but you also see little shakes in the voice. So I’m just analyzing those vocal changes to make a diagnosis. It achieved a 91.11% accuracy (amongst 81 vocal recordings) and it was validated across multiple statistical thresholds and it’s also been published in Nature Scientific Reports which means it has been peer-viewed by scientists and other professors within this field of expertise. So it has been cross-examined by other people.”


Turns out early diagnosis of Parkinson’s is crucial.

“If you can detect it early, you can treat it and mitigate the symptoms before it manifests into severe symptoms,” Shen said.

The next step for the tool is a practical application.

“Right now there’s no app or site to actually use it,” Shen said. “My next step is trying to make a website for people to actually use it for free.”

Shen said his TedX talk was about being taken seriously as a young inventor and he does feel that’s happening.

“The main idea was about breaking the boundaries of age, access, and expectation because as a 16-year-old you’re not expected to do undergrad or Master’s level research,” he said.

“But I ended up doing that. So I used my Parkinson’s tool as an end goal to talk about those boundaries. And I think the biggest takeaway from that is: no matter your age or where you come from or what people say, as long as you put your heart to something and you really work hard, you can achieve your goal.”



Shen, who will begin Grade 12 in September, is currently applying to several Canadian and American universities on the biology-life science track after he graduates.

As for his parents?

“I think they’re pretty proud of what I’ve done and no matter what they’ve always supported my endeavours whether that be financially or driving me places to present this work,” Shen said.

What you’re drinking may be causing hair loss: Study
Author of the articleenette Wilford
Published Sep 01, 2025 • 1 minute read

If you’re concerned about thinning hair, what you drink could be contributing to it.


According to a recent study published in the journal Nutrition and Health, sugary drinks, like pop, and alcoholic beverages have been linked to hair loss.


Researchers out of the Faculty of Nutrition and Food Sciences at the University of Porto in Portugal, looked at data from 61,332 participants (97% of which were women) in 17 previous studies and found that “a higher intake of alcoholic and sugary beverages was found to be positively correlated with hair loss.”

The study noted that diet and nutrition also play a “crucial role” in hair health, while supplementing with vitamin D and iron, and help with the chronic hair-loss disorder alopecia, “reducing its severity and promoting hair growth.”

The researchers noted that consuming processed food high in simple sugars may also be tied to hair loss, as the food can “stimulate the secretion of excess sebum, which promotes microbial growth on the scalp.”


They wrote: “A positive association was also observed between protein intake, the consumption of soy products, cruciferous vegetables and supplements, with improvements in hair parameters such as hair loss and hair density.”


They added: “This, in turn, exacerbates irritation and inflammation, contributing to hair loss.”

But the study authors acknowledged that few studies have examined the combined effects of foods, supplements, and nutrients on hair health, so further research is needed to confirm their findings.



“Hair is an important individual characteristic that plays a fundamental role in an individual’s self-esteem and identity,” they said, adding that hair loss has “a significant psychological and emotional impact on those affected,” and “limiting alcohol and soft drinks may be beneficial.”

Here’s what can happen if you clean your ears with a cotton swab

Be careful when using a cotton swab to clean your ears.
Be careful when using a cotton swab to clean your ears.
Is it safe to use cotton swabs to remove earwax?


Most of us have seen or used the earwax-cleaning products all over social media – high-tech lavage kits, spoons equipped with smartphone cameras, suction devices, ear candles or even classic cotton swabs.


But many of these tools are not effective and can make certain earwax issues worse or cause injuries, particularly when not performed correctly and under the care of a professional, experts cautioned.

“While all of those technologies are nifty and cool to see, they’re not the safest,” said Ana H. Kim, a neurotologist and professor of otolaryngology at Columbia University.

Earwax, or cerumen – that yellow or light brown substance – is produced by glands in the outer one-third of the ear canal, where it mixes with sweat, dead skin cells and loose hair, among other substances. And the wax has a purpose. It is intended to moisturize the skin inside the ear canal, trap dirt and debris, and help protect against bacteria and fungi, research shows.


The inner two-thirds of the ear canal is composed of bone and thin skin and does not have earwax-producing capabilities. There should not be wax that far inside, experts said.

The ear is a self-cleaning organ. When you chew or talk, your jaw movement helps push the earwax to the opening of the outer ear canal, known as the meatal opening. From there, the wax usually falls out or, when stuck, can be gently encouraged to do so, Kim said.

“After showering, when everything is moist, you can use a towel or a Q-tip, and you can swab around the entry point, not going deeper into the ear canal,” she said.

When people insert earwax removal tools such as cotton swabs into the ear canal, it not only disrupts the natural cleaning process but also can reverse that process by pushing earwax deeper inside, potentially causing a wax buildup, or an impaction, Kim said. This can lead to muffled or reduced hearing, she said.


Also, because cotton swab heads have abrasive fibres, they can scratch the delicate ear canal skin, compromising the protective barrier against bacterial and fungal invasion, she added.

Cleaning with cotton swabs can lead to more severe injuries as well.

Kim, who specializes in the inner ear and the nerves connecting to the brain, said she has seen cotton swab heads retained inside the ear canal. One study reported that cotton swabs were among the most common foreign objects found in the ears of adults visiting emergency rooms.

In more serious cases, Kim said, she has seen a cotton swab get inserted too far into the ear canal or inadvertently shoved inside when someone unknowingly swings open a bathroom door or knocks into the arm of the person holding a swab. This can puncture the eardrum and even dislodge the hearing bones, known as the ossicles, which can cause hearing loss, among other issues, she said.


Technologies that use small spoonlike tools to scrape out earwax can cause similar issues; ear candles, which are hollow cones that are placed into the ear canal and then lit at the other end, do not work and can burn the skin inside the canal; and water irrigation, when not used correctly, can be uncomfortable and cause symptoms such as dizziness, experts said.

“If you stick a Q-tip in your ear, you’ll notice that the Q-tip has some wax on it, but it’s getting half of it out and then pushing the other half deeper,” said Tiffany Chao, an assistant professor in the Department of Otorhinolaryngology – Head and Neck Surgery at the University of Pennsylvania. “The safest thing to do is to leave the deeper cleaning to somebody who has specialized training.”


There are certain skin conditions, such as eczema, dermatitis and psoriasis, that may make it more challenging for the earwax to slide out on its own, leading it to potentially build up over time and cause an impaction, Kim said.

Similarly, she said, certain anatomical differences or devices such as hearing aids can impede the natural cleaning process.

In such cases, Kim said, routine cleaning by an otolaryngologist, also known as an ear, nose and throat (ENT) doctor, may be medically necessary.

What else you should know
If you want to self-clean your ears, first see a specialist such as an ENT to make sure you do not have anatomical issues or earwax impactions, experts said.

Then consider some of these home remedies that, when performed with care, come recommended by ear-care professionals:


-Use a damp towel or a cotton swab to carefully remove visible earwax. After showering – when the earwax is soft – dampen a cotton swab with mineral oil or baby oil and gently swab in a circular motion only at the meatal opening, which is the dark shadow at the entrance of the ear canal, Kim said. “But never go inside,” she said. When looking in the mirror, “if you can’t see the tip of your Q-tip head, that means you’ve gone in too far,” she said.

-Try mineral oil or baby oil, or a homemade remedy using hydrogen peroxide, to gently break up earwax impactions. Use an eyedropper to apply one to two drops of mineral oil or baby oil into the ear canal. Or mix small amounts of saline and hydrogen peroxide in a 1:1 ratio and use an eyedropper to apply about five drops into the ear canal. Then, with either method, place a cotton ball into the outer ear and wait about 10 minutes. Remove the cotton ball before showering, letting the warm water wash out the broken-up wax, Kim said. Alternatively, there are over-the-counter earwax removal drops. These methods can be used weekly or monthly depending on how much wax your ear produces, but too often “may result in a clogged sensation if the oil is retained in the canal,” Kim said.


-Take care when using ear lavage kits, which you can buy over the counter. Be gentle and use clean water – such as distilled water, or even sterile saline – that is warmed to body temperature. Water that is too cold can be uncomfortable and cause temporary, but sometimes severe, dizziness, Chao said. Also, when the water is pushed into the ear canal with too much force, it may cause injury to the ear canal or eardrum, she said.

The bottom line: While the ear is self-cleaning and does not typically require earwax removal, experts said it is generally safe to gently wipe the meatal opening of the ear canal with a damp towel or cotton swab but not to enter the ear canal.

Study links microplastics to Alzheimer’s-like symptoms in mice
Author of the article:Washington Post

Published Sep 02, 2025 • 4 minute read

Microplastics as found in the Great Lakes. Postmedia File
A new study published by researchers at the University of Rhode Island suggests that the accumulation of microplastics in the brain could affect how it functions, finding that high amounts of microplastics could trigger Alzheimer’s-like symptoms in mice with a genetic predisposition to the disease.


There is no doubt that microplastics are in people’s brains. A study earlier this year found that an average human brain may contain about seven grams of tiny shards of plastic, or about the weight of a plastic spoon.


But researchers have been uncertain what effect – if any – those tiny particles are having on human cognition or on the advance of degenerative diseases like Alzheimer’s.

“I’m still really surprised by it,” said Jaime Ross, a professor of neuroscience at the University of Rhode Island and one of the paper’s authors. “I just can’t believe that you are exposed to these particles and something like this can happen.”

About 1 in 9 people in the United States over the age of 65 are living with Alzheimer’s disease. But the causes of the condition remain elusive, with researchers attributing it to a combination of genetic, environmental and other factors.


The paper, published last month in the journal Environmental Research Communications, examined mice that had been genetically modified to include the gene APOE4, one of the strongest risk factors for Alzheimer’s disease. People with the APOE4 gene – which affects about 25 percent of the population – are 3½ times more likely to develop Alzheimer’s than those with the most common gene variant, APOE3. Scientists believe that APOE4 may combine with other environmental or genetic factors to cause the disease.

“If you are carrying APOE4, it doesn’t mean you’re going to develop Alzheimer’s disease,” said Ross. “I don’t want to scare anybody. But it is the largest known risk factor.”

Similar to humans, mice that have been modified to contain this gene don’t necessarily develop cognitive problems, unless they are exposed to some other compounding risk factor. In some previous studies, mice with a humanoid version of the gene that were fed a high-fat diet showed problems with cognition and memory.


In the new research, Ross and her colleagues exposed the mice to just three weeks of polystyrene microplastics – the same plastics that go into Styrofoam – mixed in with their drinking water. The plastics were 0.1 micrometres to 2 micrometres in diameter – a tiny fraction of the width of a human hair. (The researchers used a high dosage of microplastics, reasoning that the mice were exposed for only a short time, compared with many years of exposure in humans.)

What they found startled the scientists. In one portion of the study, mice were put in a square pen, and their movements were tracked by cameras. Normal, healthy mice will stay by the corners, avoiding open spaces for safety. But male mice that were exposed to microplastics and had the APOE4 allele spent much more time in the centre of the pen. Female mice with the gene exposed to microplastics, meanwhile, showed evidence of memory problems when navigating a Y-shaped maze – significantly more than mice who had the gene but weren’t exposed to minuscule plastics.


Ross said that these results match human symptoms of Alzheimer’s. Men with the disease are more likely to show apathy, while women display greater memory problems. “There were very similar sex differences in mice as what people experience,” Ross explained.

University of California at San Francisco neurology professor Yadong Huang, who studies the development of Alzheimer’s disease and was not involved in the paper, said that the memory aspects of the experiment jumped out at him. Patients with Alzheimer’s fall into two camps, generally: patients who struggle primarily with executive functioning like planning and organizing, and those who suffer mostly from memory loss. Women with APOE4 alleles are more likely to have the memory-loss version.


“The novelty here is that environmental factors can trigger a similar effect,” he said. “We shouldn’t ignore that.”

Researchers can’t say for certain the role that micro and nanoplastics – which are even smaller than microplastics, measuring less than 1 micrometre – play in Alzheimer’s. Mice brains are not a perfect model for human brains, and the current study didn’t take into account the effects of aging on the development of disease.

But scientists are beginning to look more deeply into how plastic affects our brains. Matthew Campen, a toxicology professor at the University of New Mexico who was one of the first scientists to discover plastics in the human brain, said the new study raised interesting questions about how those tiny pieces of plastic enter it.


APOE4, he pointed out, affects how a set of proteins transfer fat and other materials around the body. Food and water, meanwhile, are already riddled with microplastics. “What if APOE4 is just shuttling more plastic from the mouth into the brain?” he said. “Nobody’s really looked at this.”

Even as scientists continue to research the health effects of microplastics, efforts to curb production of plastics have failed. In August, a global meeting intended to develop a plastics treaty ended without an agreement, due in part to pushback from the U.S.

Ross says her lab is moving quickly to try to understand how microplastics could be triggering or contributing to Alzheimer’s and dementia – after all, it was only a few years ago that scientists first discovered plastic in human blood. “The field is so new,” she said. “Any information will help other people design their studies.”

5 warning signs of a heart attack, according to cardiologists
Author of the article:Washington Post
Washington Post
Teddy Amenabar
Published Sep 04, 2025 • Last updated 1 hour ago • 5 minute read

Lindsay Shanks, seen here with her son, had a heart attack in 2022, when she was 37. Shanks said it never crossed her mind she was having a heart attack; she thought she had a pinched nerve.
One night, Lindsay Shanks sat up from bed and felt a sharp pain.


“It felt like someone stabbed me right between my shoulder blades,” said Shanks, who was 37 at the time. “My hands started tingling, and I got really nauseous.”


Shanks, who lives outside Detroit, assumed she was having a panic attack or had a pinched nerve. When she got to the hospital, a nurse looked at her test results and ran out of the room. Shanks was having a heart attack.

“I became very popular very quickly,” she said. “It was very hectic.”

Ben Rennert, 40, a small-business owner from Oshkosh, Wisconsin, was picking up his children from school when he felt a tingle in his arms and “well over a hundred pounds of pressure” on his chest.

“I’ve never felt something that intense before,” he said about his heart attack in March. “It’s not pleasant, to say the least.”


Heart attacks occur when blood flow to the heart stops or slows, often because a plaque rupture causes a blood clot that blocks a coronary artery, cardiologists say.

The “vast majority of people” who have a heart attack will feel a tight, squeezing or aching chest pain, said William Brady, a professor of emergency and cardiovascular medicine at the University of Virginia School of Medicine.

But not all heart attacks are the same, and there are other warning signs people don’t typically think of, said Stacey Rosen, volunteer president of the American Heart Association and executive director at Northwell’s Katz Institute for Women’s Health. In particular, women are more likely to dismiss symptoms (or have them dismissed by others) as anxiety or stress.


The Washington Post asked cardiologists about the more surprising signs and symptoms of a heart attack. Their advice: If anything feels off, tell someone and call 911. Don’t delay a trip to the hospital because the pain isn’t what you’d expect a heart attack to feel like.

“Delay can lead to irreversible heart damage,” Rosen said. “So, really, listen to your body.”

1. Jaw pain
The aching discomfort or pain from a heart attack will often radiate to other parts of the body, said James de Lemos, chair of cardiology at UT Southwestern Medical Center. The symptoms can sometimes be subtle and “less impressive” than what you see on television, he said.

“Some people will tell you it’s just my forearm that hurt – or I had really intense jaw pain that came out of nowhere,” de Lemos said.


Rosen said one of her patients met with dentist after dentist because she thought her aching jaw was because of a tooth – until one dentist suggested it could be because of her heart.

“And, in fact, it was,” Rosen said. The patient probably avoided a heart attack because of “a very intelligent and holistically thinking dentist.”

Pain from a heart attack can – but not always – travel to the left side of the body, on the same side as the heart, the cardiologists said.

Women experience chest pain more often in combination with symptoms such as back pain, nausea, dizziness or shortness of breath, Rosen said. And instead of calling it “chest pain,” they are more likely to describe their symptoms as a discomfort or fatigue.

“When someone tells me their chest is aching, that elevates my concern,” said Clyde Yancy, chief of cardiology at the Northwestern University Feinberg School of Medicine.


Ben Rennert, 40, had a heart attack in March while picking up his kids at school. He said that “the whole event lasted probably three to four minutes.”
2. Nausea and vomiting
Nausea, vomiting, acid reflux, belching and other forms of indigestion can be a sign of a heart attack, especially when the attack is affecting the lower portion – or inferior wall – of the heart, de Lemos said.

If the indigestion can’t be treated by an antacid, the gastrointestinal distress could be related to the heart, de Lemos said, particularly in a person who’s at risk for a heart attack.

3. A sense of impending doom
A heart attack can also cause someone to feel a sense of impending doom, cardiologists said. All of a sudden, “you feel like you’re going to die,” Brady said.

It’s different from “pure anxiety,” said Seth Martin, a cardiologist at Johns Hopkins Medicine. It’s physical symptoms coupled with a persistent sense that “something is seriously wrong.”


“It can be just this awareness, just a sense that something doesn’t feel right,” Yancy said. “That’s sufficient to alert my senses that we need to evaluate the heart and blood vessels.”

4. Sweaty, cold and clammy skin
A blockage in a coronary artery is an extraordinary stress on the body, Rosen said. And, when it happens, your sympathetic nervous system is overloaded, causing you to feel cold, clammy and sweaty.

If you’re carrying groceries in and your chest is suddenly tight, you’re short of breath and you’re breaking out in a sweat, these are signs of an impending heart attack, Brady said. Especially on fair-weather days when there’s no reason to perspire.

And if you find the discomfort goes away when you sit down and rest, that doesn’t mean you’re in the clear, Brady said. You should still see a doctor, he said.


5. Fatigue
A heart attack limits the circulation of oxygen through the body and to the heart, which can cause you to feel fatigued or short of breath, Martin said.

You may feel foggy but can’t pinpoint why, Rosen said.

Some people think they’re just getting older and slowing down, said Anna Bortnick, an interventional cardiologist and associate professor of medicine at Montefiore Einstein Medical Center in the Bronx. Others delay going to the hospital because they’re taking care of kids or family members.

A person with early signs of heart problems may experience symptoms only when they’re walking or doing other forms of exercise. The heart requires more blood flow when we exert ourselves, but a blockage or a weakened heart muscle is preventing that from happening, Rosen said.


Sometimes, a heart attack is like a tree trunk falling across a river, blocking all blood flow to the heart, Rosen said.

Other times, “there can be stuttering symptoms that go on for days, that get worse when the artery is more blocked,” she said. “It’s really a dynamic process for many.”

How to reduce your risk of a heart attack
You can’t replace heart muscle cells once the organ is damaged, Rosen said. If you don’t get treatment quickly enough to restore blood flow, the heart attack can affect the organ’s ability to pump blood. This could lead to heart failure, which is a chronic condition where the heart doesn’t function as well as it did.

Instead, cardiologists recommend you take steps to reduce your risk of a heart attack in the first place. Try to lower your blood pressure and cholesterol levels. Exercise regularly for at least 150 minutes a week, don’t smoke, limit how much alcohol you drink and build healthy eating habits, they said.

Rennert, from Wisconsin, said he has physically recovered from his heart attack. Last week, he biked 15 miles around town with a friend.

“It was actually my first ride on this particular bike since the heart attack, and it felt good,” he said. “It was short – but it was still good to get out.”
