New insights into the degradation dynamics of organic material in the seafloor      (via sciencedaily.com)     Original source 

Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.

Conservation of nature's strongholds needed to halt biodiversity loss      (via sciencedaily.com)     Original source 

To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.

Cosmic rays illuminate the past      (via sciencedaily.com)     Original source 

Researchers have for the first time been able to pin down a prehistoric settlement of early farmers in northern Greece dating back more than 7,000 years to the year. For this they combined annual growth ring measurements on wooden building elements with the sudden spike of cosmogenic radiocarbon in 5259 BC. This provides a reliable chronological reference point for many other archaeological sites in Southeast Europe.

Complete stellar collapse: Unusual star system proves that stars can die quietly      (via sciencedaily.com)     Original source 

University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. Their study of an unusual binary star system has resulted in convincing evidence that massive stars can completely collapse and become black holes without a supernova explosion.

Improving statistical methods to protect wildlife populations      (via sciencedaily.com)     Original source 

In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.

The impacts of climate change on food production      (via sciencedaily.com)     Original source 

A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.

Modern plant enzyme partners with surprisingly ancient protein      (via sciencedaily.com)     Original source 

Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls with significant impacts on the clean energy industry.

Hubble views the dawn of a sun-like star      (via sciencedaily.com)     Original source 

Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.

Scientists want to know how the smells of nature benefit our health      (via sciencedaily.com)     Original source 

Spending time in nature is good for us. And knowing more about nature's effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Many studies have focused on how seeing nature affects us. A team of scientists from around the world wants to understand what the nose knows. They are calling for more research into how odors and scents from natural settings impact our health and well-being.
