![]() | 'QBism': Quantum mechanics is not a description of objective reality—it reveals a world of genuine free willWhat does quantum mechanics, the most successful theory ever proposed by physics, teach us about reality? The starting point for most philosophers of physics is that quantum mechanics must somehow provide a description of the world as it is independently of us, the users of the theory. |
Earth news

![]() | Turbulence theory extended to complex atmospheric conditionsTurbulence plays an essential role in weather and climate, and correctly representing its effects in numerical models is crucial for accurate weather forecasts and climate projections. However, the theory describing the effect of turbulence has not changed since its conception in 1950s, despite the fact that it is not representative for the majority of the Earth's land surface, especially over mountains and polar regions. The Innsbruck meteorologist Ivana Stiperski has now extended the turbulence theory to complex atmospheric conditions. The researcher thus paves the way for the first generalized turbulence theory over complex terrain. |

![]() | Why tornadoes are still hard to forecast, even though storm predictions are improvingAs a deadly tornado headed toward Rolling Fork, Mississippi, on March 24, 2023, forecasters saw the storm developing on radar and issued a rare "tornado emergency" warning. NOAA's Weather Prediction and Storm Prediction centers had been warning for several days about the risk of severe weather in the region. But while forecasters can see the signs of potential tornadoes in advance, forecasting when and where tornadoes will form is still extremely difficult. |
![]() | Machine learning model helps forecasters improve confidence in storm predictionWhen severe weather is brewing and life-threatening hazards like heavy rain, hail or tornadoes are possible, advance warning and accurate predictions are of utmost importance. Colorado State University weather researchers have given storm forecasters a powerful new tool to improve confidence in their forecasts and potentially save lives. |

Now, the road has disappeared under muddy water, its path marked by sodden telephone poles that protrude from the swelling lake. Water laps just below the windows of a lone farmhouse that sits alongside the submerged route. |
![]() | Opinion: Climate doomism is bad storytelling—hope is much more effective at triggering actionWhen news about the climate is published, like the Intergovernmental Panel on Climate Change's latest report, frightening headlines like "final warning" or "now or never" are often the norm. Some activists call this approach "climate doomism", and are quick to criticize media publications and other influencers for it. Climate doomism is the view that humanity has lost the climate battle, and we feel nothing but helplessness and anxiety about it. |

![]() | Particle errors: Quantifying the effects of simulation mixing state on aerosol optical propertiesParticles in the atmosphere affect global climate. For example, the black carbon from burning fossil fuels absorbs and radiates light and heat. To calculate the effects of aerosols on climate, scientists rely on simulated aerosol fields.

This is because the simulated aerosol optical properties—how particles absorb and scatter light—are sensitive to mixing state. Mixing state refers to how various properties are distributed across the particles in the air. |

![]() | Feed them or lose them: How developing nerve cells are influenced by essential amino acidsBrain development consists of a sequence of coordinated steps, which are mainly instructed by our genes. During these steps, the proper positioning and functionality of nerve cells in the brain (neurons) are critical—nonfunctional or incorrectly positioned neurons can lead to severe neuropathological consequences. Mutations in genes coordinating this program are often linked to neurodevelopmental disorders; however, environmental stressors such as nutrient scarcity or malnutrition can also influence the development of the brain. Still, very little is known about the importance of specific nutrients and the role of metabolism during brain development. |
![]() | Study defines a newly recognized clinical condition: Cesarean scar disorderMore than 30% of women who give birth by cesarean section suffer from long-term symptoms, such as abdominal pain, blood loss or fertility problems.

This gives women recognition for these problems after a cesarean section. In addition, international studies on CSDi can now be better compared with each other, providing more insight into treatment options. The research is published today in JAMA Network Open. |

At the surface, where the hills peak, are functional colon cells that do the organ's work of absorption and secretion. Deep in the valleys are stem cells that constantly renew those functional cells. New research from Dana-Farber Cancer Institute found that the cells in those valleys can go through a transition before cancer begins. |

![]() | Psychedelics and Cognition: A New LookThe synthesis of LSD and psilocybin in the early to mid-20th century sparked not only a new counterculture in the United States but also a new interest in brain science, specifically the role of neurotransmitters. Despite these discoveries, research on psychedelics went dormant for decades due to anti-drug sentiment. A recent renaissance in psychedelic research seeks to understand how these drugs might be leveraged as tools in treating mental illness. While this work has focused largely on mathematical modeling and resting-state neuroimaging, that is now shifting: Cognitive neuroscientists are bringing new rigor to the field, using behavioral and clinical studies to investigate the cognitive effects of psychedelic drugs. |
