A study involving some 11,000 dogs demonstrated that the gender, age and breed of the dog, as well as any behavioral problems and certain environmental factors, are connected to hyperactive and impulsive behavior and inattention (ADHD).
Doctors from the U.K. report an intriguing case in which an octogenarian woman who smokes a pack of cigarettes per week refused treatment for her lung cancer — but the tumor shrankanyway. Now, the trio of doctors suspects that the woman's daily self-administration of CBD oil may be the reason for her recovery, according to a paper they published in the journal BMJ Case Reports on Thursday. There
Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling technique that is frequently used to cool atomic samples. The device used a recently developed technique the researchers call photon pressure coupling, which is predicted to be of use
The Roman Empire was ruled by 175 men, from Augustus (63 BCE-19 CE) to Constantine XI (1405-53), including the Eastern or Byzantine Empire after the split in 395 CE, but excluding those who did not rule in their own right because they were minors during regencies or co-emperors.
Archaeologists find remains of fugitive during first dig at site near Pompeii in almost three decades The partially mutilated remains of a man buried by the AD79 eruption of Mount Vesuvius at Herculaneum, the ancient Roman town close to Pompeii, have been discovered in what Italy's culture minister described as a "sensational" find. Archaeologists said the man, believed to have been aged between
In the spring of 2020, as Boston's first COVID-19 wave raged, I was the gastroenterologist on call responding to a patient hospitalized with a stomach ulcer. Wearing a layer of yellow personal protective equipment over a pair of baggy scrubs, I spent 30 minutes explaining to him that he needed an endoscopic procedure. We built a rapport, and by the end of our conversation about the pros and cons,
Bitcoin Boom In February, Tesla bought $1.5 billion worth of bitcoin as an investment and announced that it would accept the digital currency as payment for cars. That investment seems to be paying off — at least as the market stands right now. Bitcoin has soared to new heights, crossing the $60,000 threshold , making Tesla's treasure chest of 42,902 Bitcoin worth $2.5 billion. That means Tesla i
Damian Adams grew up knowing that his parents had used an anonymous sperm donor to conceive him, and as a teen, he was even proud of this identity. He considered donating to help other families have children. Becoming a father himself, however, changed everything . When his daughter was born 18 years ago, he cradled her in his arms, and he instantly saw himself in her and her in himself. He felt
Guinea Pig George Takei, who played Hikaru Sulu on hit TV show "Star Trek" alongside Captain Kirk actor William Shatner, wasn't impressed with his costar's trip to "space" earlier this week. "So 90-years-old is going to show a great deal more on the wear and tear on the human body, so he'll be a good specimen to study," Takei told tabloid Page Six . "He's boldly going where other people have gone
A 3,500-year-old image tablet of a 'miserable male ghost' gives up its secret Its outlines are faint, only discernible at an angle, but the world's oldest drawing of a ghost has been discovered in the darkened vaults of the British Museum. A lonely bearded spirit being led into the afterlife and eternal bliss by a lover has been identified on an ancient Babylonian clay tablet created about 3,500
Ignorance about the basic biology of vulvas is still shockingly high – yet there are huge health benefits, physical and emotional, to be won with better understanding If you have a vulva between your legs, could you identify the seven separate structures in a mirror? If your partner has a vulva, can you identify theirs? For over half the population, the vulva is a significant part of their body; a
Throughout the pandemic, media outlets and online dashboards have provided constant updates on the number of people who have died from COVID-19. Far less prominent—but just as striking—are the tallies of those left behind. According to an estimate published recently in the journal Pediatrics , at least 140,000 American children had lost a parent or caregiver because of the coronavirus by the end

In the opening scene of Halloween Kills , the latest edition in this indestructible franchise, a group of plucky
The Shenzhou-13 vessel docked at its space station to kick off a record-setting six-month stay Three astronauts successfully docked with China's new space station, state media said, on what is set to be Beijing's longest crewed mission to date and the latest landmark in its drive to become a major space power. The three blasted off shortly after midnight on Saturday (1600 GMT) from the Jiuquan la
Covid has turned us into pandemic experts, all too ready to gainsay scientists and distorting our reasoning, but psychology can help us understand how our prejudices are formed As I wasted an hour's worth of petrol trying to find more petrol last month, Justin Webb poked at the chief secretary to the Treasury, Simon Clarke , on the Today programme, seeking a reason why much of the country is runn
The Beatles drummer, Ringo Starr, was among those asked to add their messages to a Lucy mission plaque. The spacecraft has set off on a 12-year quest to explore eight asteroids, mostly around Jupiter's orbit. The mission was named after the 3.2m-year-old skeletal remains of a human ancestor found in Ethiopia nearly a half a century. Dr Donald Johanson discovered the remains while the Beatles song
Advanced Civilizations A Harvard scientist has an interesting theory as to how our universe was formed: in a laboratory by higher "class" of lifeform. Avi Loeb, bestselling author and the former chair of Harvard's astronomy department, penned an op-ed in Scientific American this week positing that the universe could have been formed in a lab by an "advanced technological civilization." If true, h
Henrietta Lacks died of cervical cancer more than 70 years ago — but her tumor cells still live on after her cells were taken without her consent . Though her unknowing contributions led to a number of scientific breakthroughs, it still represents a painful example of medical injustice and abuse. Now, the World Health Organization (WHO) has taken a step to right those wrongs by honoring Lacks wit
If you're already an investor in cryptocurrencies like Bitcoin, you know both the advantages and disadvantages they have over conventional money.

Clinical decisions made in the delivery setting as to whether to employ vaginal delivery or cesarean section are often made under high pressure, and with great uncertainty, and have serious consequences for mother and baby. Now, a new study of electronic health records spanning 86,000 deliveries suggests that if their prior patient had complications in one delivery mode, a physician will be more l
Hundreds of connections between different human diseases have been uncovered through their shared origin in our genome, challenging the categorization of diseases by organ, symptoms, or clinical specialty. A new study has generated data on thousands of proteins circulating in our blood and combined this with genetic data to produce a map showing how genetic differences that affect these proteins l
Between 2016 and 2018, researchers studied wild boar and rat snakes across a range of radiation exposures in Fukushima. The team examined biomarkers of DNA damage and stress and did not find any significant adverse health effects.
The immune cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels, researchers have discovered. The findings may prove important in cognitive decline, dementia and stroke, among other conditions linked to diseases of the brain's small vessels.
A study has revealed for the first time that the contraceptive pill can reduce the risk of type 2 diabetes by over a quarter in women with polycystic ovary syndrome (PCOS). The research findings also show that women with PCOS have twice the risk of developing type 2 diabetes or pre-diabetes (dysglycemia) — highlighting the urgent need to find treatments to reduce this risk.
In the fight against multidrug-resistant bacteria, scientists have developed a new kind of antibiotic-free protection for wounds that kills drug-resistant bacteria and induces the body's own immune responses to fight infections.
Plastic Pick Up A Dutch inventor has helped create an enormous device that removed nearly 20,000 lbs of plastic out of the Pacific Ocean last week. Boyan Slat founded the Ocean Cleanup , a nonprofit dedicated to removing 90 percent of floating ocean plastic by 2040, according to Insider . To that end, he and the organization created a device, dubbed "Jenny," that collects plastic in a gigantic sy
Life's too short for bad literature, so let's follow the writer's example Do you ditch a book if it does not immediately grab your attention or do you trudge through it joylessly, weighed down by some invisible obligation to complete it, no matter how arduous the task? The writer Mark Billingham got stuck into this endless debate at the Cheltenham literature festival last week, admitting that he g
Researchers may have an uncovered new answers on how to create safer opioids. Design a new opioid to bypass the part of brain that feels pleasure, but retain the analgesic properties, which make opioids one of the most effective pain relievers. Researchers looked at how opioids may have become so widely abused.
One potential cost-effective way to sustain ageing concrete subjected to harsh environmental conditions is to externally coat the material with fiber reinforced polymer composites. But few studies have looked at the durability of such strengthening. Now, researchers from Korea and the USA conduct a 13-year long experiment to find out.

NASA's Lucy spacecraft, named for an early human ancestor whose skeleton provided insights into our species' muddled origins, has begun the first leg of its 12-year journey. Lifting off from Cape Canaveral early Saturday morning on an Atlas V rocket, Lucy is headed to study asteroids in an area around Jupiter that's been relatively unchanged since the Big Bang. It will venture farther from the su
Researchers found that complex teeth, a hallmark of mammals, also evolved several times in reptiles, prompting the evolutionary success of plant-eating lizards. However, contrary to mammals their tooth evolution was not unidirectional.
In the early solar system, a 'protoplanetary disk' of dust and gas rotated around the sun and eventually coalesced into the planets we know today. A new study suggests that a mysterious gap existed within this disk around 4.567 billion years ago, and likely shaped the composition of the solar system's infant planets.
Ocean warming caused by anthropogenic greenhouse gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of survival. Researchers expect many organisms to head to the poles and form new communities — with unforeseeable consequences for marine food webs.
Magnetic solids can be demagnetized quickly with a short laser pulse, and there are already so-called HAMR (Heat Assisted Magnetic Recording) memories on the market that function according to this principle. However, the microscopic mechanisms of ultrafast demagnetization remain unclear. Now, a team has developed a new method at BESSY II to quantify one of these mechanisms and applied it to the ra
Patients who have cardiovascular disease are at increased risk of serious complications from the flu, according to a new study. The study found that not only are traditional flu-related outcomes worse among some patients with CVD, but infection in those patients also is associated with an increased risk of cardiovascular events. Getting the influenza vaccine, however, substantially reduces cardiov
The production of renewable energy is increasing every year. But after analyzing the growth rates of wind and solar power in 60 countries, researchers conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. The article "National growth dynamics of wind and solar power compared to the growth required for global climate targets" was published in t
