The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.

When witch hazel plants are ready to disperse their seeds, the woody seed capsules split open, pressure builds up, and eventually the seeds shoot out like a bullet fired from a rifle, hitting 30 feet per second in less than five milliseconds. In a new study, researchers looked into how witch hazels manage to fling heavier seeds just as fast as lighter ones. The secret lies in their spring-loaded fruits.

Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.

Researchers have designed a new type of quantum computer that uses fermionic atoms to simulate complex physical systems. The processor uses programmable neutral atom arrays and is capable of simulating fermionic models in a hardware-efficient manner using fermionic gates. The team demonstrated how the new quantum processor can efficiently simulate fermionic models from quantum chemistry and particle physics.

Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.

Many plants and crops rely on insects to pollinate them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded as pests, in plant diversity and evolution.

New research has revealed Australia's iconic grasstrees -- known as 'yaccas' -- play a critical role in protecting wildlife from deadly weather extremes, thereby ensuring their survival. But the grasses themselves are under threat due to back burning, clearing and disease.

New research shows that a single mutation that has immediate effects on plant fitness is maintained over the long term in natural plant populations, despite theories predict the contrary. The researchers located and identified the gene that regulates the amount of an active defense hormone. Mutants in this gene are susceptible to herbivore attack. However, they compensate for impaired defenses through robust genetic networks. When fewer herbivores attack, they even grow faster and produce more offspring.

Quantum physicists have successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer. This is the first step in doing highly challenging quantum transport calculations on quantum hardware and, as the hardware improves over time, such work promises to shed new light in condensed matter physics and materials science.

Young vegetables known as microgreens are reputed to be particularly good for health. But are microgreens the superfood they're claimed to be, and how do they compare to mature veggies? Scientists have found that their nutritional profiles differ, as do their effects on gut bacteria. Yet, tests in mice suggest that both microgreen and mature vegetables can limit weight gain.

One of the biggest obstacles to the uptake of plant-based alternatives to meat is their very dry and astringent feel when they are eaten. Scientists are now revolutionizing the sensation of plant proteins, transforming them from a substance that can be experienced as gloopy and dry to one that is juicy and plump. And the only substance they are adding to the plant proteins is water.

New findings have found that water use efficiency has stalled since 2001 which implies not as much CO2 was being taken in by plants and more water was consumed and that could have implications on carbon cycling, agricultural production and water resources.
