Following the arrival of the first farmers in Scandinavia 5,900 years ago, the hunter-gatherer population was wiped out within a few generations, according to a new study. The results, which are contrary to prevailing opinion, are based on DNA analysis of skeletons and teeth found in what is now Denmark.

Researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user's earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.

Saturn's moon Mimas harbors a global ocean beneath its icy shell, discovered through analysis of its orbit by Cassini spacecraft data. This ocean formed just 5-15 million years ago, making Mimas a prime candidate for studying early ocean formation and potential for life. This discovery suggests life-essential conditions might exist on seemingly inactive moons, expanding our search for life beyond Earth.

Two astrophysicists have finally solved a 20-year-old astrophysical puzzle concerning the lower-than-expected amounts of the element sulphur found in Planetary Nebulae (PNe) in comparison to expectations and measurements of other elements and other types of astrophysical objects. The expected levels of sulphur have long appeared to be 'missing in action'. However, they have now finally reported for duty after hiding in plain sight, as a result of leveraging highly accurate and reliable data.

The rivers of Australia, which once flowed across its now dry interior, used to host a range of bizarre animals -- including a sleek predatory lobe-finned fish with large fangs and bony scales. The newly described fossil fish discovered in remote fossil fields west of Alice Springs has been named Harajicadectes zhumini by palaeontologists.

Experts have discovered how to create different colors of blue cheese. After discovering how the classic blue-green veining is created, a team of experts were able to create a variety of different fungal strains that could be used to make cheese with colors ranging from white to yellow-green to red-brown-pink and light and dark blues.

Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially point to ways to prevent quantum coherence loss.

Scientists completed several successful attempts to fire 28 kilojoules of laser energy at small capsules filled with deuterium and tritium fuel, causing the capsules to implode and produce a plasma hot enough to initiate fusion reactions between the fuel nuclei. These results demonstrate an effective 'spark plug' for direct-drive methods of inertial confinement fusion.

Scientists have discovered that adding a layer of magnesium improves the properties of tantalum, a superconducting material that shows great promise for building qubits, the basis of quantum computers. The scientists show that a thin layer of magnesium keeps tantalum from oxidizing, improves its purity, and raises the temperature at which it operates as a superconductor. All three may increase tantalum's ability to hold onto quantum information in qubits.

Researchers have succeeded in generating a logical qubit from a single light pulse that has the inherent capacity to correct errors.

Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.

In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.

Zebrafish are smaller than your little finger, with a brain no more than half the size of a pinhead. Yet these animals possess an efficient navigation system that enables them to find their way back to spots in the water where the temperature suits them.
