QUT evolutionary biologist Dr Matthew Phillips used molecular dating from DNA sequences to challenge the dominant scientific theory that placental mammals diversified 20 million years before dinosaurs became extinct.
The dinosaurs’ long reign was not ended swiftly but by torturous millennia of climate change before and after a giant asteroid slammed into Earth, scientists have said.
The impact at Chicxulub in modern-day Mexico certainly contributed to the disappearance of the dinosaurs, but was by no means the sole cause, a team concluded in a study published in Nature Communications.
Mesozoic butterflies seem to have appeared so similar to today’s incarnation that at a few paces you’d probably not notice a difference. They evolved 165 million years ago, disappearing just 45 million years later, a full 45 million years before the first modern caterpillar decided to grow up and become a beee-youuuu-tee-ful butterfly. Again.
Workers digging up a busy street in the Mexican city of Tultepec have delighted paleontologists with a mammoth find - literally!
The skeleton of the long-extinct behemoth - which experts believe grew to 16 feet tall and weighed as much as 10 tonnes - was found while workers were carrying out drainage work in the the city's suburb of San Antonio Xahuento.
There are many aspects of William Shakespeare’s world that modern readers might find confusing, such as the importance of heraldry. Earning—and being able to afford—an official crest was a sign that a family was respectable, and often came with the title of “gentleman.” “It’s an early form of brand management,” Heather Wolfe, a curator at the Folger Shakespeare Library in Washington, D.C., tells Sadie Dingfelder at The Washington Post. “You pay a lot of money to get this logo created and you put it on everything.”
Archaeologists excavating a Roman-era synagogue at the site of Huqoq, Israel, have uncovered two new panels of a mosaic floor with instantly identifiable subjects—Noah's ark, and the parting of the Red Sea during the Israelite exodus from Egypt.

The woman was laid on a bed of specially selected materials, including gazelle horn cores, fragments of chalk, fresh clay, limestone blocks and sediment.
Tortoise shells were placed under and around her body, 86 in total. Sea shells, an eagle’s wing, a leopard’s pelvis, a forearm of a wild boar and even a human foot were placed on the body of the mysterious 1.5 meter-tall woman. Atop her body, a large stone was laid to seal the burial space.
The so-called German Stonehenge near Pommelte, where there was apparent human sacrifice, has been under reconstruction for several years and has just opened to the public for the first time. The 4,300-year-old site, which was originally constructed in the late Neolithic or early Bronze Age, might more properly be called the “Woodhenge” of Germany because it was made of 1,200 locust tree logs.
Italy’s culture minister has set the stage for events to take place within the walls of the Colosseum, as the ancient amphitheatre undergoes a fresh phase of restoration work.
Mysterious tattoos on a 3,000-year-old female mummy have triggered new interrogations about the role of women in the religion of Ancient Egypt. Her body is decorated with elaborate tattoos representing lotus flowers, cows, and baboons as well as wadjet eyes – a very religious symbol.
One of the key mysteries in the realm of quantum physics is the role of the observer, or more precisely, consciousness. As Nobel laureate Eugene Wigner once explained, when this relatively new branch of physics came into being, it was found that "it was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness."
Our brains are aware not just of our bodies but also the immediate space around us. Now, a twist on the classic rubber hand illusion can make people “feel” this space – a sensation they liken to perceiving a “force field”.
People more open to Fantasy, which results in them being more cognitively attentive to music, are more likely to experience “frisson”, according to a study published this May in Psychology of Music. This contrasts with previous research that had repeatedly highlighted the relationship between frisson and the emotional aspects of an individual’s personality type.
Imagine if each of the words in this article had their own taste, or the music you’re listening to played out as visual scene in your mind. For synaesthetes – a small proportion of people whose senses intertwine – this is the stuff of the every day. “Most people describe it as a gift,” says Jamie Ward, a neuroscientist at the University of Sussex in the UK.
Babies and other newborn animals aren’t just amazingly cute by accident – the cuteness on show is actually crucial for their survival, and is intended to trigger vital caregiving behaviours.
Researchers at the University of Cambridge have discovered one more reason why dogs are great: their superior sense of smell is inspiring advancements in the medical field.

The saying “like a moth to a flame” might have to be snuffed out. Some moths in light-flooded urban areas have evolved to resist artificial lights, according to a new study in Biology Letters.
Evolution follows the path of least resistance, which can result in suboptimal physical traits that don't ideally match the functional need, according to a new analysis by University of Arkansas anthropologist Peter Ungar.
Biologists from Queen Mary University of London (QMUL) have discovered that the evolutionary history of a hormone responsible for sexual maturity in humans is written in the genes of the humble starfish.
Uranium mining in Australia is polluting the Antarctic, about 6,000 nautical miles away.
University of Maine climate scientists made the discovery during the first high-resolution continuous examination of a northern Antarctic Peninsula ice core.
Exactly what powered the dynamo remains a mystery. One possibility is that the lunar dynamo was self-sustaining, like Earth’s: As the planet has cooled, its liquid core has moved in response, sustaining the dynamo and the magnetic field it produces. In the absence of a long-lived heat supply, most planetary bodies will cool within hundreds of millions of years of formation.
Astronomers have detected what may be the most-rapidly-rotating, ultra-cool, brown-dwarf star ever seen. The super-fast rotation period was measured by using the 305-meter Arecibo radio telescope—the same telescope that was used to discover the first planets ever found outside our solar system.
Early Mars might have had both liquid water on its surface and oxygen in its atmosphere, according to a new study published in Geophysical Research Letters.
Findings by NASA’s Curiosity and Opportunity rovers reveal that, beneath the Red Planet’s dusty surface lurk substantial deposits of manganese oxide, a compound likely created by a marriage of liquid water and atmospheric oxygen.
Five years and 1.8bn miles into its voyage, Nasa’s Juno spacecraft is about to slam on its brakes and fall into orbit around the vast, cloud-striped planet of Jupiter.

The aviation industry told us it was impossible to build an airplane that could fly day and night without a drop of fuel. In 2015, Solar Impulse proved that it could be done, and together with last week’s transatlantic flight, we proved that change is possible when we have the right mindset and are not afraid to push back our own limits.
A small team of researchers with members from France, the U.K., Canada and Germany has discovered that the great frigate bird (Fregata minor) is able to stay aloft for up to two months at a time. In their paper published in the journal Science, the team describes how they affixed trackers to several of the birds as part of a two-year study, what they found, and even offer some ideas on how the birds manage to sleep.
Don’t be alarmed, but our sun has just ‘gone blank’ - with a total lack of sunspots leaving the surface like a snooker ball.
It’s part of the sun’s cycles - a sign that the ‘solar minimum’ is approaching - and some experts have suggested a new ‘mini ice age’ might be on the way.

Arctic wilderness tales often wax poetic about dazzling displays of northern lights painting the skies. But for at least the past century, some of those stories have also mentioned eerie noises associated with especially powerful auroras.
Astronomers are using the NASA/ESA Hubble Space Telescope to study auroras -- stunning light shows in a planet's atmosphere -- on the poles of the largest planet in the Solar System, Jupiter.
Until Galileo kick-started modern astronomy in the early 1600s, the record of the sun's activities was basically blank—or so scientists thought. To shed light on our star's history, researchers at Kyoto University in Japan have begun to comb through ancient texts. So far they have found dozens of apparent references to sunspots, auroras and other solar events that date as far back as the seventh century—albeit in terms that require more interpretation than Galileo's drawings.
In the Caucasus mountains of Russia, not far from the cities Tzelentzchik, Touapse, Novorossiysk and Sochi, there are hundreds of megalithic monuments known as dolmens. Russian and foreign archaeologists have not yet discovered their use.
A team of archaeologists diving near the Greek island of Antikythera have reported a startling new discovery from a previously explored 2,000-year-old shipwreck. The find — a very heavy, metal cylinder — offers new insights into the maritime warfare of ancient times, the scientists say.

A monumental Roman gate discovered in the excavations by the University of Haifa at Hippos may cast light on the bronze mask of Pan – the only object of its kind found anywhere in the world – that was discovered in the same site during last year’s excavation season.
In the Classical world, chariot races were the equivalent of today’s highest-profile sports and had the highest-paid athletes in history. But how did the chariot horses of North Africa cope with the searing heat? Archaeologists have now found the answer after unearthing an advanced system that cooled the horses and kept the popular races running at the Roman Circus of Carthage in Tunisia 2,000 years ago.
It was a toilet that witnessed the birth of America: a humble pit latrine, or privy pit, dug deep into the ground behind a small Philadelphia house in the late 18th century.
Latrines don't generally stir excitement, but archaeologists were thrilled to find the brick-lined circular shaft while excavating a site at the corner of South Third and Chestnut Streets in the summer of 2014.
Perhaps the greatest female pharaoh other than Cleopatra VII, Hatshepsut (ruled 1473-1458 B.C.) was not the first woman to take power as sole monarch in the Two Lands.

Some things never change and terrorism is one of them. Archeologists digging in an ancient Roman battleground in Scotland discovered a new type of rock used when battles were fought by soldiers propelling them with slings. The rocks had mysterious holes drilled in them and new research has determined that these tiny weapons were not meant to kill but to terrorize the enemy.
Furnaces for advanced metal production have been found under a dirt track used by summer tourists. Archaeologists walking to a beauty spot on Lake Baikal chanced across the unique ancient furnaces after noticing slag and clay coating on a rough road used by tourists to access the shoreline.
Construction of a new highway in Hårup, southwest Denmark, has unearthed farms and houses from the Middle Ages, including a rare Viking dødehus or "death house" dated to 950 C.E., packed with grave goods that reveal a lot about the three people buried within it.
For the first time, pieces of living bone have been grown from the cells of patients — in this case, miniature pigs — and sculpted to replace missing anatomical structures.
The custom-engineered bone was used to successfully repair a pig's lower jaw, one of the strongest and most complex jaws in the face, paving the way for bone repairs that could be carried out elsewhere in the body, the researchers said.
Physicists working with the Large Hadron Collider beauty experiment (LHCb) have discovered what appears to be an entire family of new particles that our current physics models can’t explain.
A Southwest Research Institute-led team has discovered an elusive, dark moon orbiting Makemake, one of the "big four" dwarf planets populating the Kuiper Belt region at the edge of our solar system.
Around 4.6 billion years ago, our solar system was a chaos of collapsing gas and spinning debris. Small particles of gas and dust clumped together into larger and more massive meteoroids that in turn smashed together to form planets. Scientists believe that shortly after their formation, these planets -- and particularly Mercury -- were fiery spheres of molten material, which cooled over millions of years.
NASA researchers have found that several volcanic deposits on Mercury's surface require mantle melting to have started close to the planet's core-mantle boundary, which lies only 400km below the planets surface and making it unique in the solar system.
While there's no shortage of exoplanets being discovered these days, finding signs of alien life could be a heck of a lot easier if we stuck to our own Solar System – which is why a group of scientists in the US want to launch a new mission to explore Saturn's icy moon Enceladus.

There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery. New evidence published this week in the leading journal Science shows for the first time that the ocean's overturning circulation slowed during every one of those temperature plunges - at times almost stopping.
What if the way things smell started to change? What if food inexplicably lost its aroma and your house no longer had its familiar homely scent? It would certainly be off-putting, but you’d probably manage. However, many animals depend on their sense of smell much more than we do, so they would probably be affected much more acutely by a change in this key sense.

On Tuesday, scientists in the United Kingdom published a study charting the relationship between light pollution and the timing when trees produce buds. By observing four tree species, they found that on average, artificial light may cause trees to bud more than seven days earlier than their naturally occurring counterparts.
Adaptation to climate change has a lag of several thousands of years, report researchers. The permafrost regions in the Arctic are among those areas of the world in which the temperature is rising particularly fast due to climate change. However, biologists are currently observing that the tree vegetation is only minimally adapting to these changes. In those areas where pine and spruce trees should be growing according to the air temperature, the Siberian larch is still thriving.
An international team of scientists from Oxford University, UK, and Tel-Hai College, Israel, has shown that pea plants can demonstrate sensitivity to risk - namely, that they can make adaptive choices that take into account environmental variance, an ability previously unknown outside the animal kingdom.
The grunts made by pigs vary depending on the pig's personality and can convey important information about the welfare of this highly social species, new research has found.

The Universe is becoming gradually cleaner as more and more cosmic dust is being mopped up by the formation of stars within galaxies, an international team of astronomers has revealed.
"The dips found by Kepler are real. Something seems to be transiting in front of this star and we still have no idea what it is!" confirms German astronomer Michael Hippke. Even if aliens are not involved, Tabby's star remains "the most mysterious star in the universe" as Yale astronomer Tabetha Boyajian described it in a TED talk she gave last February.
