Scientists recommend proactive response to the shifting range of plant invaders
2021-06-14
(Press-News.org) WESTMINSTER, Colorado - June 06, 2021 - Many invasive plants are expanding their growing range in response to climate change, making early detection and rapid response more critical than ever. Limited resources, though, can make it impossible to track and manage every range-shifting species.
To help invasive species managers bring focus their efforts, a team from the University of Massachusetts suggests prioritizing potential invaders based on the threat they represent.
In a research project featured in the journal Invasive Plant Science and Management, the team explored data on 87 plant species that are projected to shift into northern New England as the climate in the region changes. Using a widely accepted rating protocol, they evaluated and scored each species for its potential to cause harm.
The team found that 22 of the invaders were known to threaten native species common in New England. Sixteen of those species were also known to have a negative impact on agriculture, human health or the economy. Almost all were found to be readily available for purchase by home gardeners - a factor that could accelerate their introduction.
"Because these high-risk species are not yet widespread across the Northeast, state and local regulators have the unique opportunity to prohibit their introduction and to establish proactive best practices for monitoring and management," says William Coville, a member of the University of Massachusetts research team.
To learn more, read the article "Identifying high-impact invasive plants likely to shift into northern New England with climate change", which is currently available online.

A plant-based diet appears to afford significant protection to rats bred to become hypertensive on a high-salt diet, scientists report. When the rats become pregnant, the whole grain diet also protects the mothers and their offspring from deadly preeclampsia.
Although we have all heard to avoid the salt shaker, an estimated 30-50% of us have a significant increase in blood pressure in response to high-salt intake, percentages that are even higher and more impactful in Blacks.
The two new studies provide more evidence that the gut microbiota, which contains trillions of microorganisms that help us digest food and plays a key role ...

In cultures that place a high value on conventional gender norms, particularly those that prize men as the breadwinners in a family, their unemployment plays an outsized role in whether a romantic relationship ultimately succeeds or fails.
That's according to new research from sociologists Pilar Gonalons-Pons of the University of Pennsylvania and Markus Gangl of Goethe University Frankfurt. They published their findings in the journal END ...

Haifa, Israel June 11, 2021 - Using an ultrafast transmission electron microscope, researchers from the Technion - Israel Institute of Technology have, for the first time, recorded the propagation of combined sound and light waves in atomically thin materials.
The experiments were performed in the Robert and Ruth Magid Electron Beam Quantum Dynamics Laboratory headed by Professor Ido Kaminer, of the Andrew and Erna Viterbi Faculty of Electrical & Computer Engineering and the Solid State Institute.
Single-layer materials, alternatively known as 2D materials, are in themselves novel materials, solids consisting of a single layer of atoms. Graphene, the first 2D material discovered, was isolated for the first time in 2004, an achievement ...

Researchers at the Keck School of Medicine (KSOM) of USC are among the contributors to a large-scale ethnically diverse genetic study that has expanded what we know about potential causes of type 2 diabetes.
The research, published in Nature Genetics, was conducted by the international MAGIC collaboration, made up of 400 global academics and led by researchers at the University of Exeter.
The study, a genome-wide meta-analysis, has identified more regions of the genome that are linked to blood glucose and insulin levels, features that contribute to the ...

The build-up of calcium in a major blood vessel is linked with a 39 per cent higher risk of serious falls in older women, new Edith Cowan University (ECU) research has found.
This calcium build-up, known as abdominal aortic calcification (AAC), is a hardening of the abdomen's largest artery, which can be identified early on a commonly used bone density machine scan.
The study's findings could help health professionals to identify people at risk of serious falls early to prevent future falls and their potentially life changing consequences.
Foiling future falls
Falls are a growing public health concern, causing the deaths of an estimated 680,000 people globally each year. They are also one of ...

Hokkaido University researchers have developed a simple method that converts existing generic polymers into luminescent polymers using mechanical force.
Researchers from Hokkaido University have successfully developed a new method to give luminescent properties to generic polymers, such as polystyrene and polyethylene. The technique, which was published in the journal Angewandte Chemie International Edition, makes it possible to easily prepare luminescent polymers without using complicated organic synthetic methods.
"Luminescent polymers are widely used in modern society, in applications such as organic lasers, solar cells, sensors and bioimaging, but their preparation often requires multiple chemical synthesis steps, which are both time ...

The biophysical modelling study, published in The Lancet Planetary Health, challenges outdated public health guidance that discourages fan use in temperatures higher than 35 degrees Celsius / 95 degrees Fahrenheit.
Based on human studies carried out at the University of Sydney's Thermal Ergonomics Laboratory, the researchers developed a model to determine the humidity-dependent temperature thresholds at which fans could become detrimental, providing conditions that exacerbate heat stress.
"The effectiveness of a fan depends on temperature and ...

In the field of quantum measurement, weak values, introduced in 1988 by Aharonov, Albert and Vaidman (AAV), represent undoubtedly one of the most intriguing and puzzling paradigm, with many properties in sharp contrast with respect to traditional (projective) quantum measurements.
In fact, by weakening the coupling between measured particle and measuring device, and exploiting suitable pre- and postselection, AAV demonstrated that it was possible to obtain a value of 100 while (weakly) measuring the spin of a ½-spin particle.
Such a result was obtained after averaging on multiple measurements on identically pre- and postselected ...

The gold standard in functional brain imaging for over two decades, functional magnetic resonance imaging (fMRI) has transformed the landscape of research and clinical care. Yet, because of its cost and functional limitations, scientists have continued to look for new ways to see into the human brain.
Researchers from the Keck School of Medicine of USC and the California Institute of Technology (Caltech), with the help of patients recovering from traumatic brain injury, have now demonstrated an alternative way to produce highly detailed images of the human brain. Their work, published in END ...

BURLINGTON, VT -- Findings from a study on the feasibility of addressing anxiety, pain and stress with Olfactory Virtual Reality (OVR) -- a new form of VR that incorporates the sense of smell into its augmented reality -- paint a clearer picture for clinical psychiatrists about how it could be used to safely and effectively help mental health and mood disorders. What's more, it holds promise for improved access and inclusion of patients impacted by physical limitations or constraints, such as patient mobility, comorbidities and safety.
Building on previous research proving VR's effectiveness in "distraction for pain and medical procedures, relaxation and calming, and immersion therapy for trauma, PTSD and ...
