Marsupials key to discovering the origin of heater organs in mammals      (via sciencedaily.com)     Original source 

Around 100 million years ago, a remarkable evolutionary shift allowed placental mammals to diversify and conquer many cold regions of our planet. New research shows that the typical mammalian heater organ, brown fat, evolved exclusively in modern placental mammals. The research team demonstrated that marsupials, our distant relatives, possess a not fully evolved form of brown fat. They discovered that the pivotal heat-producing protein called UCP1 became active after the divergence of placental and marsupial mammals. This finding is crucial for understanding the role of brown fat in mammalian evolution, endothermy, and metabolism.

'Open gates' in warming Arctic are expanding salmon range      (via sciencedaily.com)     Original source 

New research has connected warming ocean temperatures to higher Pacific salmon abundance in the Canadian Arctic, an indicator that climate change is creating new corridors for the fish to expand their range. Salmon haven't historically been seen in large numbers in the Arctic Ocean and its watersheds, but in recent years incidental catches by subsistence fishermen have occasionally surged. Researchers working together with communities in the western Canadian Arctic, connected those salmon booms with a sequence of warm, ice-free conditions in the Arctic Ocean north of Alaska.

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.

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.

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.

Paving the way for hydrogen from algae enzymes      (via sciencedaily.com)     Original source 

Under certain conditions, some algae are able to produce hydrogen -- a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present. Researchers have identified how such a cofactor, the so-called hydrogen cluster, is assembled. Specifically, they describe the previously unexplained role of the enzyme HydF, which is involved in the final steps of assembly.
