Seventy thousand years ago, the sea level was much lower than today. Australia, along with New Guinea and Tasmania, formed a connected landmass known as Sahul. Around this time—approximately 65,000 years ago—the first humans arrived in Sahul, a place previously devoid of any
A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These two qualities are reflected in its name: dark matter.
Herds of endangered hippos stuck in the mud of dried-up ponds are in danger of dying in drought-struck Botswana, conservation authorities told AFP Friday.
In the last several decades, large forest fires have increasingly threatened communities across the Mediterranean. Climate change is expected to make these fires larger, hotter, and more dangerous in the future. But fire management lessons from the past could help to improve
Emmanuelle Butty, med.vet., DACVIM (SAIM), assistant clinical professor at Cummings School of Veterinary Medicine, sometimes treats dogs with leptospirosis, an infection that can lead to kidney failure and even death.
While it can be hard for us to notice as we go about our busy lives, cities are filled with indigenous plants, fungi, insects, spiders and other little creatures, as well as birds, frogs and reptiles.
A collaborative research team from NIMS and Tokyo University of Science has successfully developed an artificial intelligence (AI) device that executes brain-like information processing through few-molecule reservoir computing. This innovation utilizes the molecular vibrations
The hyper-arid desert of Eastern Sudan, the Atbai Desert, seems like an unlikely place to find evidence of ancient cattle herders. But in this dry environment, my new research has found rock art over 4,000 years old that depicts cattle.
Traditional memory devices are volatile and the current non-volatile ones rely on either ferromagnetic or ferroelectric materials for data storage. In ferromagnetic devices, data is written or stored by aligning magnetic moments, while in ferroelectric devices, data storage
Researchers at the University of Minnesota Twin Cities College of Science and Engineering co-led a new study by an international team that will improve the detection of gravitational waves—ripples in space and time.
University of Minnesota Twin Cities researchers have constructed a robot that uses machine learning to fully automate a complicated microinjection process used in genetic research.
Genome sequencing technology provides thousands of new plant genomes annually. In agriculture, researchers merge this genomic information with observational data (measuring various plant traits) to identify correlations between genetic variants and crop traits like seed count,
Scientists have introduced a form of quantum entanglement known as frequency-domain photon number-path entanglement. This advance in quantum physics involves an innovative tool called a frequency beam splitter, which has the unique ability to alter the frequency of individual
To celebrate the launch of our new event series in the US, kicking off with a masterclass on the brain and consciousness, we have unlocked five incredible long reads
One of the many secrets to bacteria's success is their ability to defend themselves from viruses, called phages, that infect bacteria and use their cellular machinery to make copies of themselves.
Inside the cell nucleus, the DNA molecule is found in a densely packed DNA-protein complex known as chromatin. Here the DNA is wrapped around a core of histone proteins and densely packed to form nucleosomes. The structure of the nucleosomes determines which genes are
The late physicist Joseph Polchinski once said the existence of magnetic monopoles is "one of the safest bets that one can make about physics not yet seen." In its quest for these particles, which have a magnetic charge and are predicted by several theories that extend the
A new study has revealed for the first time the vital role carbon dioxide (CO2) plays in determining the lifespan of airborne viruses—namely SARS-CoV-2, the virus that causes COVID-19. It clearly showed keeping CO2 levels in check helps to reduce virus survival, and therefore
California may be a leader in the fight against climate change, but the state is years, even decades, behind other states when it comes to granting environmental rights to its citizens.
Japan's space agency announced Friday a plan to launch a major upgrade to its satellite imaging system, as a new flagship rocket is put to the test for a third time.
Just like the animals on Noah's Ark, the corals arrived in a pair. On Monday, divers with gloved hands gently nestled the self-bred corals from the World Coral Conservatory project among their cousins in Europe's largest coral reef at the Burgers' Zoo in the Netherlands.
Globally, lightning is responsible for over 4,000 fatalities and billions of dollars in damage every year; Switzerland itself weathers up to 150,000 strikes annually. Understanding exactly how lightning forms is key for reducing risk, but because lightning phenomena occur on
Self-assembling molecules that spontaneously organize themselves to form complex structures are common in nature. For example, the tough outer layer of insects, called the cuticle, is rich in proteins that can self-assemble.
