Early summer fishing can have an evolutionary impact, resulting in smaller salmon      (via sciencedaily.com)     Original source 

A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.

New technique reveals how gene transcription is coordinated in cells      (via sciencedaily.com)     Original source 

Researchers invented a technique that allows them to observe which genes and enhancers are active in a cell at the same time. This could help them determine which enhancers control which genes and may reveal potential new drug targets for genetic disorders.

Father's diet before conception influences children's health      (via sciencedaily.com)     Original source 

A recent study provides new insights into how fathers' diets and overweight can affect their children's health even before conception. The findings of the study can help develop preventive health measures for men wishing to become fathers: The healthier the father's diet, the lower the risk for their children to develop obesity or diseases such as diabetes later in life.

Exploring three frontiers in marine biomass and blue carbon capture      (via sciencedaily.com)     Original source 

A new study offers first-time insights into three emerging climate innovations to safeguard or increase the carbon naturally captured by ocean and coastal ecosystems: rapid interventions to save the Great Barrier Reef, satellite-tracked kelp beds in the deep ocean, and seagrass nurseries in the United Kingdom.

Small, but smart: How symbiotic bacteria adapt to big environmental changes      (via sciencedaily.com)     Original source 

Lucinid clams, inconspicuous inhabitants of the seafloor and one of the most diverse group of animals in the ocean, rely on symbiotic bacteria for their survival. Researchers now reveal the evolutionary journey of these tiny tenants. Faced with a drastically changing environment following the closure of the Isthmus of Panama, they acquired new metabolic skills to enable their own survival. Understanding the adaptive strategies of bacteria provides insight into their potential responses to challenging environmental changes, such as those caused by human activities.

New light shed on circadian rhythms      (via sciencedaily.com)     Original source 

Circadian clocks, which drive circadian rhythms, are entwined with many essential systems in living things including plants, fungi, insects, and even humans. Because of this, disruptions to our circadian clocks are linked to higher disease rates in humans, including certain cancers and autoimmune diseases.

Frequent mowing puts poisonous weed into survival mode      (via sciencedaily.com)     Original source 

A study has found that frequent mowing of Solanum elaeagnifolium, also known as silverleaf nightshade, may help create a 'superweed.' A professor of entomology and plant pathology has been studying silverleaf nightshade for more than a decade. New findings have shown that the more silverleaf nightshade was mowed, the more it developed ways to avoid destruction. The taproot went down further, nearly 5 feet deep, in the first generation of mowed plants. More spikes popped out on the stem as a defense against caterpillars feeding on the flowers. The flowers became more toxic to caterpillars, leading to less pressure from natural predators.

Key nutrients help plants beat the heat      (via sciencedaily.com)     Original source 

Scientists have discovered some of the molecular mechanisms controlling how plants -- including important crops like soybean and rice -- will respond to rising global temperatures, finding higher temperatures make root systems grow faster, but sustaining this increased growth speed depends on high levels of nitrogen and phosphorus in the soil. The discoveries point to the necessity of nitrogen and phosphorus-rich soil to promote crop growth and create nutritious crops, in addition to aiding a mission to create more resilient crops in the face of climate change.

The embryo assembles itself      (via sciencedaily.com)     Original source 

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.

Urgent need for action now for increasing threat from invasive alien species      (via sciencedaily.com)     Original source 

Urgent action now is needed to tackle the major and growing global issue of invasive alien species, says a team of 88 experts from 47 countries. The paper follows the (IPBES) thematic assessment report on invasive alien species and their control. The experts say co-developing management actions with multiple stakeholders including government and private sector stakeholders, and Indigenous Peoples and local communities will be critical to achieving success in addressing biological invasions.
