Published The microbiome of fruit and vegetables positively influences diversity in the gut
(via sciencedaily.com) Original source In a meta-study, a research team has provided evidence that the consumption of fruit and vegetables contributes positively to bacterial diversity in the human gut.
Published Certain per- and polyfluoroalkyl 'forever chemicals' identified as potential risk factor for thyroid cancer
(via sciencedaily.com) Original source Researchers have discovered a link between certain per- and polyfluoroalkyl substances (PFAS) and an increased risk for thyroid cancer.
Published Discovery finds ferns produce crop-saving insecticide
(via sciencedaily.com) Original source Researchers have solved the structure of a novel insecticidal protein that is effective in protecting major crop plants like corn and soybean from pests and is naturally produced by ferns.
Published Climate is increasing risk of high toxin concentrations in Northern US lakes
(via sciencedaily.com) Original source As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research. The findings identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.
Published Plants transformed into detectors of dangerous chemicals
(via sciencedaily.com) Original source What if your house plant could tell you your water isn't safe? Scientists are closer to realizing this vision, having successfully engineered a plant to turn beet red in the presence of a banned, toxic pesticide.
Published Fungal evolution discovered: Mycena can now invade living hosts
(via sciencedaily.com) Original source Biologists have long known mushrooms of the genus Mycena, commonly known as bonnet mushrooms, as fungi that live off of dead trees and plants. New research demonstrates that bonnets can also find their ways into young, healthy trees and plants, where they try to cooperate. In doing so, they have made an evolutionary leap which challenges our understanding of the ecological roles of fungi.
Published Increased West Antarctic Ice Sheet melting 'unavoidable'
(via sciencedaily.com) Original source The West Antarctic Ice Sheet will continue to increase its rate of melting over the rest of the century, no matter how much we reduce fossil fuel use, according to new research. A substantial acceleration in ice melting likely cannot now be avoided, which implies that Antarctica's contribution to sea level rise could increase rapidly over the coming decades.
Published Contaminants in cannabis and hemp flowers create potential for health risks
(via sciencedaily.com) Original source Cannabis use, even for medical purposes, could make some people sick due to harmful fungi that contaminate the plants. That is the finding of a recently published peer-reviewed journal article, whose authors recommend further study and consideration of changes to regulations to protect consumers, especially those who are immunocompromised. They examined data, previous studies, and U.S. and international regulations related to the cannabis and hemp industry.
Published Does urbanization trigger plant evolution?
(via sciencedaily.com) Original source Urban environments have become hotspots for understanding how rapid evolution occurs in response to extreme environmental changes. These habitats exert selective pressures on resident organisms that impact their evolutionary trajectories. Recently, researchers investigated how the creeping woodsorrel plant might adapt in response to elevated temperatures that result from urbanization. Understanding these effects can help predict evolutionary traits to manage plant evolution in the face of shifting climatic conditions.
Published Land use: Producing more food and storing more carbon
(via sciencedaily.com) Original source Doubling food production, saving water, and increasing carbon storage capacity -- this may sound paradoxical, but would be theoretically feasible considering the biophysical potential of the Earth. Reaching this goal, however, would require a radical spatial reorganization of land use.
Published Pivotal breakthrough in adapting perovskite solar cells for renewable energy
(via sciencedaily.com) Original source A huge step forward in the evolution of perovskite solar cells will have significant implications for renewable energy development.
Published New extremes in stratospheric water vapor
(via sciencedaily.com) Original source The focus of new research was to determine how deep, how much and how frequently water in the stratosphere was being increased by thunderstorms.
Published El Niño's changing patterns: Human influence on natural variability
(via sciencedaily.com) Original source Two recent scientific studies provide new insights into Earth's climate dynamics, with a particular focus on the El Niño phenomenon. The results show how El Niño responds to natural factors over extended periods, while highlighting the increasing role of human activities in shaping this climatic phenomenon in the modern era.
Published You say genome editing, I say natural mutation
(via sciencedaily.com) Original source A plant geneticist and computational biologist teamed up to decipher the unpredictability of natural and engineered mutations in tomatoes. They discovered some combinations of mutations behave as expected while others are more erratic. Their work may help scientists find some order in the chaos of evolution and genome editing.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published New study finds 50-year trend in hurricane escalation linked to climate change
(via sciencedaily.com) Original source New research by climate scientists indicates that there have been great changes to Atlantic hurricanes in just the past 50 years, with storms developing and strengthening faster.
Published Cut emissions and improve farming to protect wilderness
(via sciencedaily.com) Original source Humanity must cut carbon emissions and use farmland more efficiently to protect our planet's remaining wilderness, new research shows.
Published Urgent action needed to address climate change threats to coastal areas
(via sciencedaily.com) Original source Global coastal adaptations are 'incremental in scale', short-sighted and inadequate to address the root causes of vulnerability to climate change, according to an international team of researchers.
Published Yeast speeds discovery of medicinal compounds in plants
(via sciencedaily.com) Original source Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.
Published Biodegradable plastics still damaging to fish
(via sciencedaily.com) Original source Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.
