A new study has discovered that trained dogs were surprisingly accurate in detecting Parkinson's disease . This development has come as a ray of hope for the Parkinson's community, as there are currently no definitive early diagnostic tests for the disease.The latest findings have given hope to scientists, as this data will help them identify the biological markers that dogs are able to detect, according to Dogster.com. Identifying the earliest changes in the body could result in improved tests, allowing patients to get timely care, as the study suggests that dogs can detect symptoms potentially years before diagnosis.Parkinson's is a neurological disorder that leads to symptoms such as stiffness, tremors, trouble with balance, and slow movement. It is progressive and worsens as time goes on. While there is no cure at present, medications and sometimes surgery can help manage symptoms.There is still no conclusive test for diagnosing Parkinson's, so finding the biological markers that dogs can sense may be valuable. Symptoms can first appear up to 20 years before they are persistent enough for a clear diagnosis. An early detection test could give patients and doctors a significant advantage in managing the disease.The research published on July 15, 2025, in The Journal of Parkinson's Disease claimed that dogs can detect the disease. But the question is, how is this possible?According to Dogster.com, the study features a double-blind study involving trained dogs. Seborrheic dermatitis, a skin condition caused by glands producing too much sebum, is one of the early symptoms of Parkinson's , often appearing before motor issues. Sebum has a unique smell, and researchers thought dogs might be trained to detect the extra sebum in skin samples.In the study, professional trainers taught a group of dogs to detect Parkinson's from skin samples. Ten dogs started the training, but just two finished the challenging process. After completing their training, the dogs were presented with a series of skin samples, one of which might have had Parkinson's. The study was double-blind, making sure the dogs weren't influenced by their trainers or the researchers.In the end, the dogs were 98% accurate at detecting Parkinson's disease from the skin samples. Their sensitivity to the samples was also high, between 70% and 80%. While this is only an initial step toward creating an early test for Parkinson's, the findings were promising.Dogs have demonstrated the ability to sense several diseases, including cancer. Cancerous tumors release volatile organic compounds that some dogs' keen sense of smell can pick up. They may also be able to detect conditions like diabetes, malaria, and COVID-19.

Five ancient human species that lived alongside modern humans revealed: New insights into our prehistoric cousins

The five ancient human cousins Neanderthals (Homo neanderthalensis) Denisovans (Homo sp. Denisova) Homo naledi Homo floresiensis Live Events Homo erectus A shared evolutionary tapestry (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel In a remarkable revelation that reshapes our understanding of human evolution , scientific research confirms that Homo sapiens—modern humans—were not alone for much of their early history. Between approximately 300,000 and 40,000 years ago, several closely related ancient human species lived alongside us, interacted with us, and in some cases interbred with our ancestors. Far from being the solitary pinnacle of evolution, Homo sapiens shared the planet with a diverse cast of human relatives whose legacy lingers in our DNA and in our the best-known and closest extinct relatives of modern humans, Neanderthals first appeared about 400,000 years ago. Unlike the outdated stereotype of brutish cavemen, they were highly intelligent, sporting brains on average larger than modern humans. Adapted to cold Eurasian climates, they had stocky bodies, large noses to warm inhaled air, and used sophisticated tools, clothing, and studies reveal that 1–2% of DNA in Europeans and Asians today originated from Neanderthals, influencing aspects such as immune system function. Their extinction roughly 40,000 years ago did not end their contribution to our genetic only in 2008 from a tiny finger bone in Siberia's Denisova Cave, Denisovans remain one of the most mysterious human cousins. DNA sequencing shows they diverged from Neanderthals about 550,000 to 765,000 years ago and lived from roughly 300,000 to 25,000–30,000 years ago in parts of Asia. Genetic evidence indicates adaptations such as dark skin, eyes, and hair, with physical traits somewhat reminiscent of one genome from a bone fragment revealed a first-generation hybrid with a Neanderthal mother and a Denisovan father. Fossil and genetic evidence suggest they inhabited a wide ecological range—from Siberia's cold caves to Southeast Asia's tropical forests—illustrating a previously hidden human in South Africa in 2013, Homo naledi is an enigmatic species. With a small brain size of around 465–560 cm³, comparable to earlier ancestors like Australopithecus, yet living contemporaneously with Homo sapiens roughly 335,000 to 236,000 years ago, Homo naledi defies simple evolutionary assumptions. Standing about 1.44 meters tall, they had long fingers and an anatomy suggesting strong climbing ability. Their diet likely consisted of nuts, tubers, and other plant matter, pointing to a different ecological niche from early modern they left no known genetic trace in modern populations, their coexistence with Homo sapiens underscores the complex diversity of human morphology and behavior during the late "Hobbits" due to their small stature, Homo floresiensis was discovered in 2003 on Indonesia's Flores island. These tiny humans stood only about 1.1 meters tall and had brains around 400 cm³ in size. Despite these archaic features, their use of stone tools and ability to hunt dwarf elephants point to a sophisticated species. They are believed to have descended from Homo erectus populations that underwent island floresiensis likely survived until around 60,000 to 38,000 years ago, potentially overlapping with Homo sapiens in Southeast Asia. Some anthropologists speculate their presence might have inspired local myths such as the Ebu Gogo—small forest-dwelling people from Flores of the longest-surviving human species, Homo erectus appeared about 1.9 million years ago and was the first human species known to leave Africa and colonize large areas of Europe and Asia. They showed significant evolutionary advances, including fully upright posture, use of fire, and persistence hunting—chasing prey until it collapsed from brain size and body shape were more human-like than earlier hominins, and they are considered direct ancestors of later human species, including Homo heidelbergensis, which is thought to be a common ancestor of Neanderthals, Denisovans, and Homo sapiens. Fossil evidence suggests H. erectus survived in parts of Asia until about 140,000 years findings highlight that humans did not evolve in isolation but rather as part of a broad family of ancient human groups exhibiting rich biological and ecological diversity. Our direct ancestors interbred with some of these species, notably Neanderthals and Denisovans, weaving their genes into ours and inheriting traits that helped us adapt to new environments.

What is the Tintina fault in Canada - nation's silent giant that could unleash massive destruction?

Live Events FAQs (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel For over 40 million years, the Tintina fault in Canada's Yukon Territory was thought to be a sleeping geological giant, as per a report. But a new study from the University of Victoria (UVic) indicates that it might not be inactive as the seismic threat could produce one of the nation's strongest earthquakes, as per a Scitechdaily almost 1,000 kilometres through northwestern Canada, the Tintina fault has slid sideways by some 450 kilometres since it formed, according to the report. Scientists thought that until recently, it had long since given up any major activity, but a new examination of the terrain around Dawson City, employing topographic data from the ArcticDEM dataset from satellite images, light detection and ranging (lidar) surveys conducted with aeroplanes and drones, has found something disturbing, as reported by latest research found that a 130-kilometre portion of the fault near Dawson City showed signs of many big earthquakes during the Quaternary Period, which spans from the past 2.6 million years to the present, as reported by Scitechdaily. This means that the fault may still be active and capable of producing significant future earthquakes, according to the Finley, a recent UVic PhD graduate and lead author of an article in Geophysical Research Letters, pointed out that 'Over the past couple of decades, there have been a few small earthquakes of magnitude 3 to 4 detected along the Tintina fault, but nothing to suggest it is capable of large ruptures,' as quoted in the Scitechdaily added that 'The expanding availability of high-resolution data prompted us to re-examine the fault, looking for evidence of prehistoric earthquakes in the landscape,' as quoted in the in most of Canada, seismic hazard estimates are known with the help of historical earthquake records, such as Indigenous oral histories, archived documents, and readings from modern seismic networks, as reported by Scitechdaily. However, major faults can remain quiet for thousands of years between large earthquakes, so that means some important seismic risks may go undetected without geological investigation, as reported by the Scitechdaily Scitechdaily report explained that when earthquakes are large and/or shallow, they often rupture the Earth's surface and produce a linear feature in the landscape, which is known as a fault found ancient glacial landforms, some as old as 2.6 million years, have been pushed sideways by about 1,000 meters along the Tintina Fault, as per the report. While other formations, about 132,000 years old, were displaced by 75 meters, as reported by Scitechdaily. These shifts are signs that the fault has moved multiple times over the past few million years, each time likely slipping several meters during powerful earthquakes, according to the Scitechdaily the landforms, which are about 12,000 years old, are not offset by the fault, which shows that no large ruptures have occurred since that time, as per the report. The fault continues to accumulate strain at an average rate of 0.2 to 0.8 millimetres per year, which means that it poses a future earthquake threat, as reported by highlighted that, 'We determined that future earthquakes on the Tintina fault could exceed magnitude 7.5,' as quoted in the report. The researcher explained that, 'Based on the data, we think that the fault may be at a relatively late stage of a seismic cycle, having accrued a slip deficit, or build-up of strain, of six meters in the last 12,000 years. If this were to be released, it would cause a significant earthquake,' as quoted by the Tintina Fault were to unleash a magnitude 7.5 earthquake or anything stronger, it could shake Dawson City with serious force, with tremors that wouldn't just rattle buildings, they could disrupt major highways and threaten vital mining operations that the region relies on, as per the research suggests it might still be active, despite being considered dormant for millions of years, as per the Scitechdaily runs about 1,000 km across northwestern Canada, passing near Dawson City in the Yukon Territory, as per the Scitechdaily report.
