| Researchers set record by preserving quantum states for more than 5 seconds Posted: 02 Feb 2022 12:38 PM PST A team of researchers has maintained a qubit coherence time for a record five seconds. The qubits are made from silicon carbide, widely found in lightbulbs, electric vehicles and high voltage electronics. |
| What is your dog’s lifespan? You might be surprised Posted: 02 Feb 2022 08:18 AM PST The Dog Aging Project, founded in 2018, is by far the most ambitious project tackling the question of canine longevity, enrolling and studying tens of thousands of dogs of all sizes, breeds and backgrounds to develop a thorough understanding of canine aging. Their open-source dataset will give veterinarians and scientists the tools to assess how well a specific dog is aging and will set the stage for further research into healthy aging -- in both dogs and people. One of their most intriguing avenues of inquiry will analyze the DNA of exceptionally long-lived dogs, the 'super-centenarians' of the dog world. |
| UK plants flowering a month earlier due to climate change Posted: 01 Feb 2022 05:11 PM PST Climate change is causing plants in the UK to flower a month earlier on average, which could have profound consequences for wildlife, agriculture and gardeners. |
| Climate change has likely begun to suffocate the world’s fisheries Posted: 01 Feb 2022 01:10 PM PST By 2080, around 70 percent of the world's oceans could be suffocating from a lack of oxygen as a result of climate change, potentially impacting marine ecosystems worldwide, according to a new study. The new models find mid-ocean depths that support many fisheries worldwide are already losing oxygen at unnatural rates and passed a critical threshold of oxygen loss in 2021. |
| Paternal alcohol use increases frequency of fetal development issues Posted: 01 Feb 2022 01:10 PM PST Prenatal visits have traditionally focused almost exclusively on the behavior of mothers, but new research continues to suggest that science should be looking more closely at the fathers' behavior as well. |
| Moons may yield clues to what makes planets habitable Posted: 01 Feb 2022 11:40 AM PST Because the moon is so important to life on Earth, scientists conjecture that a moon may be a potentially beneficial feature in harboring life on other planets. Most planets have moons, but Earth's moon is distinct in that it is large compared to the size of Earth; the moon's radius is larger than a quarter of Earth's radius, a much larger ratio than most moons to their planets. New research finds that distinction significant. |
| Scientists unveil promising new approach to diabetes prevention Posted: 01 Feb 2022 11:40 AM PST A team of scientists has conducted promising early tests of a new strategy that might one day be used to prevent or treat type 2 diabetes. The scientists tested an experimental compound called IXA4 in obese mice. They showed that the compound activates a natural signaling pathway that protects the animals from harmful, obesity-driven metabolic changes that would normally lead to diabetes. |
| Did comet's fiery destruction lead to downfall of ancient Hopewell? Posted: 01 Feb 2022 11:39 AM PST The rapid decline of the Hopewell culture about 1,500 years ago might be explained by falling debris from a near-Earth comet that created a devastating explosion over North America, laying waste to forests and Native American villages alike. Researchers found evidence of a cosmic airburst at 11 Hopewell archaeological sites in three states stretching across the Ohio River Valley. |
| Posted: 01 Feb 2022 11:39 AM PST Astronomers have confirmed the existence of the second Earth Trojan asteroid known to date, the 2020 XL5, after a decade of search. |
| First virus infection linked with infections later in life Posted: 01 Feb 2022 08:52 AM PST Asymptomatic viral infections in the first days and weeks of a baby's life are associated with an increased risk of respiratory infections later in life, research suggests. |
| Posted: 01 Feb 2022 08:51 AM PST A new study revealed a pathological brain activity that precedes the onset of Alzheimer's first symptoms by many years: increased activity in the hippocampus during anesthesia and sleep, resulting from failure in the mechanism that stabilizes the neural network. The researchers believe that the discovery of this abnormal activity during specific brain states may enable early diagnosis of Alzheimer's, eventually leading to a more effective treatment of a disease that still lacks effective therapies. |
| Posted: 01 Feb 2022 04:45 AM PST A new study provides evidence for high cognitive abilities in early humans who lived 170,000 years ago. Researchers discovered that the early humans who occupied a cave had placed their hearth at the optimal location -- enabling maximum utilization of the fire for their activities and needs while exposing them to a minimal amount of smoke. |
| What the rise of oxygen on early Earth tells us about life on other planets Posted: 31 Jan 2022 01:15 PM PST When did the Earth reach oxygen levels sufficient to support animal life? Researchers have discovered that a rise in oxygen levels occurred in step with the evolution and expansion of complex, eukaryotic ecosystems. Their findings represent the strongest evidence to date that extremely low oxygen levels exerted an important limitation on evolution for billions of years. |
| Posted: 31 Jan 2022 12:32 PM PST A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered. |
| Posted: 31 Jan 2022 08:05 AM PST Our sensory systems provide us with immediate information about the world around us. Now researchers have created a sensory map for smell. The map details how the fruit fly's olfactory receptor neurons, the components that sense smell, are organized within the insect's sensory hairs. |
| Extreme exoplanet has a complex and exotic atmosphere Posted: 28 Jan 2022 11:13 AM PST An international team analyzed the atmosphere of one of the most extreme known planets in great detail. The results from this hot, Jupiter-like planet that was first characterized with the help of the CHEOPS space telescope, may help astronomers understand the complexities of many other exoplanets -- including Earth-like planets. |
| Zika vaccine shows promising results in preclinical studies Posted: 27 Jan 2022 02:26 PM PST A Zika virus vaccine candidate is effective at preventing the Zika virus passing from mother to fetus in preclinical animal studies, according to a new study. |
| Cosmic physics mimicked on table-top as graphene enables Schwinger effect Posted: 27 Jan 2022 11:15 AM PST Researchers have succeeded in observing the so-called Schwinger effect, an elusive process that normally occurs only in cosmic events. By applying high currents through specially designed graphene-based devices, the team succeeded in producing particle-antiparticle pairs from a vacuum. |
| Scientists explain mysterious finger-like features in solar flares Posted: 27 Jan 2022 08:43 AM PST Astronomers have presented a new explanation for the mysterious downward-moving dark voids seen in some solar flares. |
| Where did that sound come from? Posted: 27 Jan 2022 08:43 AM PST Neuroscientists developed a computer model that can localize sounds. The model, which consists of several convolutional neural networks, not only performs the task as well as humans do, it also struggles in the same ways that humans do when the task is made more difficult by adding echoes or multiple sounds. |
| New experiment results bolster potential for self-sustaining fusion Posted: 27 Jan 2022 08:00 AM PST For more than 60 years, scientists have sought to understand and control the process of fusion, a quest to harness the vast amounts of energy released when nuclei in fuel come together. A new paper describes recent experiments that have achieved a burning plasma state in fusion, helping steer fusion research closer than it has ever been to its ultimate goal: a self-sustaining, controlled reaction. |
