The idea of two sexes is simplistic. Biologists now think there is a wider spectrum than that.
Asteroid Florence will fly by Earth on 1 September at a safe distance of seven million km or "18 Earth-Moon" distances. Florence is about 4.4km wide and is known to be one of the largest near-Earth asteroids according to Nasa. Near-Earth objects are heavenly bodies that enter the Earth's neighbourhood influenced by the gravity of nearby planets.
he detection of weak radio signals is a ubiquitous problem in the modern world. Everything from NMR imaging and radio astronomy to navigation and communication depends on picking up faint radio signals that would have been undetectable just a few decades ago. That’s why many groups are racing to find better ways to spot these signals and to process them using state-of-the-art techniques.
Experts say a petroglyph in New Mexico's Chaco Canyon may depict a solar eclipse from 920 years ago.
The technique could eliminate one of the biggest problems in bioprinting.
First, someone might pour molten turkey fat down a drain. A few blocks away, someone else might flush a wet wipe down a toilet. When the two meet in a dank sewer pipe, a baby fatberg is born. Eventually, more fat, oil, and grease congeal onto the mess and build up into giant stinking globs. When they get big enough, fatbergs can clog sewers entirely, sending raw sewage gushing into streets. By the time a 15-ton monstrosity was pulled from the sewers of London’s Kingston borough in 2013...
Australian researchers have reported a major breakthrough in the relief of deadly peanut allergy with the discovery of a long-lasting treatment they say offers hope that a cure will soon be possible. In clinical trials conducted by scientists at Melbourne's Murdoch Childrens Research Institute, children with peanut allergies were given a probiotic along with small doses of a peanut protein over an 18-month period.
California has a history of going it alone to protect the environment. Now, as US President Donald Trump pulls back on climate science and policy, scientists in the Golden State are sketching plans for a home-grown climate-research institute — to the tune of hundreds of millions of dollars per year.
Smart people tend to perform better at work, earn more money, be physically healthier, and be less likely to subscribe to authoritarian beliefs. But a new paper reveals that a key aspect of intelligence – a strong “pattern-matching” ability, which helps someone readily learn a language, understand how another person is feeling or spot a stock market trend to exploit – has a darker side: it also makes that person more likely to learn and apply social stereotypes.
Hyundai Motor Co said on Thursday it was placing electric vehicles at the center of its product strategy - one that includes plans for a premium long-distance electric car as it seeks to catch up to Tesla and other rivals.
It's a common refrain from whiskey enthusiasts: Adding a few drops of water to a glass opens up the flavors of the drink. Chemists in Sweden provide a molecular explanation for why this works.
When you open Facebook on Monday, a special message about the 2017 total solar eclipse will promote NASA's live-streaming video feeds.
Researchers hope the data will guide patients to effective treatments.
Glowing "jellyfish" galaxies have revealed a new way to power some of the most powerful objects in the universe. The same process that feeds the most voracious black holes at the galactic centers may also create dangling "tentacles" of newborn stars, a new study found.
Jhonathan Miranda never expected to be into birds. But when the Venezuelan biologist got a job at a bird lab as a university student, he set his mind to learning as much as he could about the class Aves. As he organized trips around the country, one particular species lodged in his mind: the Táchira Antpitta, a round, leggy brown bird a little longer than a pencil.
How do touch screens work? And why do bananas work just as well as your finger but pens don't?
A new study from ANU on a 400 million year old fish fossil has found a jaw structure that is part of the evolutionary lineage linked to humans. The fossil comes from ancient limestones around Lake Burrinjuck, 50 kilometres northwest of Canberra. The area is rich in fossil shells and corals, but also home to the rare skulls of extinct armoured fish called placoderms.
Today the phrase 'all roads leads to Rome' means that there's more than one way to reach the same goal. But in Ancient Rome, all roads really did lead to the eternal city, which was at the centre of a vast road network.
Drift analysis of debris reveals new coordinates for potential impact location
These advances raise practical questions we have never had to address before.
Archaeologists have discovered three tombs that date back around 2,000 years in southern Egypt. They were found in burial grounds in the Al-Kamin al-Sahrawi area in Minya province, south of Cairo. The tombs contained a collection of different sarcophagi, or stone coffins, as well as clay fragments.
Price labels influence our liking of wine: The same wine tastes better to participants when it is labeled with a higher price tag. Scientists from the INSEAD Business School and the University of Bonn have discovered that the decision-making and motivation center in the brain plays a pivotal role in such price biases. The medial prefrontal cortex and the ventral striatum are particularly involved in this. The results have now been published in the journal Scientific Reports.
If you read our post a few weeks ago about the very messy legal fight between Snopes and Proper Media, you may recall that we spent many, many words explaining how the story was way, way, way more complicated than most in the media were portraying it...
A new study is adding to evidence that a popular class of pesticides can harm wild bees, like bumblebees.
The vast majority of coastal countries on Earth are missing out on a valuable resource to ensure future food security, according to newly published research. Published in the journal Nature Ecology and Evolution, the research has found that the world’s oceans contain numerous “hot spots” for marine aquaculture, or ocean-based fish farms, which could produce 15 billion tonnes of fish every year: over 100 times current seafood consumption globally.
A breakthrough could lead to easier, faster and cheaper vaccines.
Wind and solar energy reduce combustion-based electricity generation and provide air-quality and greenhouse gas emission benefits. These benefits vary dramatically by region and over time. From 2007 to 2015, solar and wind power deployment increased rapidly while regulatory changes and fossil fuel price changes led to steep cuts in overall power-sector emissions.
Carrying extra weight could raise your risk of heart attack by more than a quarter, even if you are otherwise healthy. Researchers have found that being overweight or obese increases a person’s risk of coronary heart disease (CHD) by up to 28 per cent compared to those with a healthy bodyweight, even if they have healthy blood pressure, blood sugar and cholesterol levels.
There's growing evidence poo transplants can work for some conditions, including a type of diarrhoea. But they're not for everyone.
Data from the 2016 US National Science Foundation report [PDF] on global Science & Engineering Indicators shows the stunning ascendancy of China’s research and development funding and output. The report paints a sobering picture for the future of US leadership in science, showing that China is graduating more scientists, rapidly increasing the quality of its research and even more rapidly increasing its research and development funding.
Pressure to feel upbeat can make you feel downbeat, while embracing your darker moods can actually make you feel better in the long run, according to new UC Berkeley research. “We found that people who habitually accept their negative emotions experience fewer negative emotions, which adds up to better psychological health,” said study senior author Iris Mauss, an associate professor of psychology at UC Berkeley.
Last Friday, Hans Nilsson in Sweden finally caught sight of an elusive creature he'd been trying to capture on film for three years straight.
An elderly couple died holding hands surrounded by loved ones in a rare double euthanasia. Nic and Trees Elderhorst, both 91, died in their hometown of Didam, in the Netherlands, after 65 years of marriage. The couple both suffered from deteriorating physical health over the past five years, with Mr Elderhorst left with reduced mobility after a stroke in 2012.
Last week, a team of astronomers reported the first potential discovery of an exomoon–a satellite orbiting a planet around another star. Part of what is so striking about the report is the scale of this possible planet-moon system. In this case, the “moon” appears to be about the size of Neptune; the planet it orbits is some 10 times the mass of Jupiter, or about 3,000 times the mass of Earth!
What we eat can influence more than our waistlines. It turns out, our diets also help determine what we smell like. A recent study found that women preferred the body odor of men who ate a lot of fruits and vegetables. Whereas men who ate a lot of refined carbohydrates (think: bread, pasta) gave off a smell that was less appealing.
In honor of this milestone I said that I would get back on my BMX bike and ride at my skate park for the first time since my accident 10 months ago when I broke my neck, smashed my skull, had three brain bleeds, and was expected to be paralyzed from the neck down! I have been so lucky throughout my recovery but this video proves that there is light at the end of every dark tunnel you just need the will and determination to find it.
The researchers don’t yet know the cause, but it likely involved fitness and diet.
SpaceX has successfully launched yet another rocket, this one carrying a Dragon capsule loaded with over 6,400 pounds of cargo destined for the International..
Striking at a myth with facts may only shore it up, a new study suggests. Researchers found that three main intervention strategies for combating anti-vaccine lies and falsehoods were ineffective at changing minds. But perhaps more concerning, they found that over-time exposure to the interventions strengthened participants’ belief in those lies and falsehoods, researchers recently reported in PLOS One. The researchers speculate that the mere repetition of a myth during the process of debunking may be enough to entrench the myth in a believer’s mind.
Honey and other bee products have a life-giving, almost mystical quality according to alternative medicine practitioners and "back to nature" enthusiasts. In truth, they don't. Bee colonies aren't tiny pharmaceutical companies. Sure, honey tastes good, but from a chemistry standpoint, honey isn't all that different from high-fructose corn syrup.
As a scientist working for decades on national and global water and climate challenges, I must speak out against what I see as an assault on America’s water resources. I grew up in New York in the 1960s hearing about massive Polychlorinated Biphenyl – a toxic chemical used as a coolant – contamination in the Hudson River and the threatened extinction of bald eagles and ospreys from eating contaminated fish.
Awaken not the Elder Things, lest they and their shoggoths again battle foul Cthulhu
A 94-million-year-old climate change event that severely imperiled marine organisms may provide some unnerving insights into long-term trends in our modern oceans, according to a Florida State University researcher. In a study published today in the journal Science Advances, Assistant Professor of Geology Jeremy Owens traces a 50,000-year period of ocean deoxygenation preceding an ancient climate event that dramatically disturbed global ocean chemistry and led to the extinction of many marine organisms. He also draws parallels to similar rates of oxygen depletion observed in our contemporary oceans.
In a major step towards creating a tricorder, University of Illinois at Urbana-Champaign researchers have invented a device that allows smartphones to perform the kinds of lab-grade medical diagnostic tests that previously had to be done on large and expensive instruments. The device, called a spectral transmission-reflectance-intensity (TRI)-Analyzer, plugs into a smartphone and is able to run tests on a patient’s blood, urine, or saliva as reliably as clinic-based instruments that cost thousands of dollars. The researchers say their TRI Analyzer costs only $550.
A sleeping brain can form fresh memories, according to a team of neuroscientists. The researchers played complex sounds to people while they were sleeping, and afterward the sleepers could recognise those sounds when they were awake. The idea that humans can learn while asleep, a concept sometimes called hypnopaedia, has a long and odd history. It hit a particularly strange note in 1927, when New York inventor A. B. Saliger debuted the Psycho-phone. He billed the device as an "automatic suggestion machine."
