Published Artificial 'power plants' harness energy from wind and rain
(via sciencedaily.com)
Original source 
Fake plants are moving into the 21st century! Researchers developed literal 'power plants' -- tiny, leaf-shaped generators that create electricity from a blowing breeze or falling raindrops. The team tested the energy harvesters by incorporating them into artificial plants.
Published Silkmoths: Different olfactory worlds of females and males
(via sciencedaily.com)
Original source 
Female moths primarily use their sense of smell to find the best host plants on which to lay their eggs, with the deterrent effect of caterpillar feces playing an important role, according to new research.
Published Climate change threatens global forest carbon sequestration, study finds
(via sciencedaily.com)
Original source 
Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.
Published Experiment could test quantum nature of large masses for the first time
(via sciencedaily.com)
Original source 
A new experiment could in principle test the quantumness of an object regardless of its mass or energy.
Published Solid-state qubits: Forget about being clean, embrace mess
(via sciencedaily.com)
Original source 
New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits, a new paper shows.
Published New rice lines for Africa offer virus protection
(via sciencedaily.com)
Original source 
The so-called Rice Yellow Mottle Virus (for short: RYMV) is responsible for high crop losses in Africa, particularly among small-scale farmers. A research team has now produced rice lines that are resistant to the disease by means of genome editing. The rice varieties are a preliminary step toward being able to generate resistant locally adapted elite varieties for small-scale food producers in Africa.
Published Human activity facilitates invasive plants' colonization in Mediterranean ecosystems
(via sciencedaily.com)
Original source 
Some invasive plants can form persistent banks of seeds that remain under the soil for years, and this makes their eradication practically impossible. Over time, this invisible population of large quantities of living, buried plants -- in seed form -- will reoccupy ecosystems and displace the typical flora of the natural environment.
Published Generating stable qubits at room temperature
(via sciencedaily.com)
Original source 
Quantum bits, or qubits, can revolutionize computing and sensing systems. However, cryogenic temperatures are required to ensure the stability of qubits. In a groundbreaking study, researchers observed stable molecular qubits of four electron spins at room temperature for the first time by suppressing the mobility of a dye molecule within a metal-organic framework. Their innovative molecular design opens doors to materials that could drive the development of quantum technologies capable of functioning in real-world conditions.
Published First direct imaging of small noble gas clusters at room temperature
(via sciencedaily.com)
Original source 
Scientists have succeeded in the stabilization and direct imaging of small clusters of noble gas atoms at room temperature. This achievement opens up exciting possibilities for fundamental research in condensed matter physics and applications in quantum information technology. The key to this breakthrough was the confinement of noble gas atoms between two layers of graphene.
Published Toxic algae blooms: Study assesses potential health hazards to humans
(via sciencedaily.com)
Original source 
Water samples from 20 sites were tested using a panel of immortalized human cell lines corresponding to the liver, kidney and brain to measure cytotoxicity. Results show that each control toxin induced a consistent pattern of cytotoxicity in the panel of human cell lines assayed. Known toxins were seen only during blooms. Because cell toxicity was seen in the absence of blooms, it suggests that there might be either emergent toxins or a combination of toxins present at those times. Findings suggest that other toxins with the potential to be harmful to human health may be present in the lagoon.
Published Iron influences plant immunity and may promote resiliency against climate change
(via sciencedaily.com)
Original source 
Researchers discovered that plants manage iron deficiency without helping 'bad' bacteria thrive by eliminating the molecular signal for iron deficiency, and that the iron deficiency signaling pathway and the plant immune system are deeply intertwined. Their findings provide a new target for boosting plant resilience in the face of climate change, and offer new insight into plant and animal microbiomes.
Published Scientists name the most common tropical tree species
(via sciencedaily.com)
Original source 
Researchers have found almost identical patterns of tree diversity across the world's tropical forests. The study of over one million trees across 1,568 locations found that just 2.2% of tree species make up 50% of the total number of trees in tropical forests across Africa, the Amazon, and Southeast Asia. Each continent consists of the same proportion of a few common species and many rare species.
Published Plant warfare: The crucial function of Nrc proteins in tomato defense mechanisms
(via sciencedaily.com)
Original source 
New research delves into the intricate defense mechanisms of tomatoes against the notorious bacterial pathogen, Pseudomonas syringae pv. tomato (Pst). It's a classic tale of nature's arms race: as pathogens evolve to outsmart plant defenses, plants counter with more sophisticated immune responses.
Published Researchers demonstrate that quantum entanglement and topology are inextricably linked
(via sciencedaily.com)
Original source 
Researchers have demonstrated the remarkable ability to perturb pairs of spatially separated yet interconnected quantum entangled particles without altering their shared properties.
Published New study uses machine learning to bridge the reality gap in quantum devices
(via sciencedaily.com)
Original source 
A study has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the 'reality gap': the difference between predicted and observed behavior from quantum devices.
Published Scientists engineer plant microbiome to protect crops against disease
(via sciencedaily.com)
Original source 
Scientists have engineered the microbiome of plants for the first time, boosting the prevalence of 'good' bacteria that protect the plant from disease. The findings could substantially reduce the need for environmentally destructive pesticides.
Published Why are bees making less honey? Study reveals clues in five decades of data
(via sciencedaily.com)
Original source 
Honey yields in the U.S. have been declining since the 1990s, with honey producers and scientists unsure why, but a new study has uncovered clues in the mystery of the missing honey.
Published Researchers improve seed nitrogen content by reducing plant chlorophyll levels
(via sciencedaily.com)
Original source 
Chlorophyll plays a pivotal role in photosynthesis, which is why plants have evolved to have high chlorophyll levels in their leaves. However, making this pigment is expensive because plants invest a significant portion of the available nitrogen in both chlorophyll and the special proteins that bind it. As a result, nitrogen is unavailable for other processes. In a new study, researchers reduced the chlorophyll levels in leaves to see if the plant would invest the nitrogen saved into other process that might improve nutritional quality.
Published Non-toxic quantum dots pave the way towards CMOS shortwave infrared image sensors for consumer electronics
(via sciencedaily.com)
Original source 
Researchers have fabricated a new high-performance shortwave infrared (SWIR) image sensor based on non-toxic colloidal quantum dots. They report on a new method for synthesizing functional high-quality non-toxic colloidal quantum dots integrable with complementary metal-oxide-semiconductor (CMOS) technology.
Published New reptile on the block: A new iguana species discovered in China
(via sciencedaily.com)
