MSU economist's research on colony collapse disorder published in national journal
The work of a Montana State University professor examining the economic impacts of colony collapse disorder among commercial honeybees was published in the Journal of the Association of Environmental and Resource Economists last month.
Work less to save the planet? How to make sure a four-day week actually cuts emissions
The idea of a four-day working week is gaining traction. Recently, several high-profile companies have trialled reduced hours. And in the UK, the Labour Party has pledged a 32-hour four day work week within ten years should it come to power.
Do nature documentaries make a difference?
Nature documentaries raise species awareness and promote pro-conservation behaviours, but don't lead to donations to conservation charities, a new Irish study has revealed.
Sun science has a bright future on the moon
There are many reasons NASA is pursuing the Artemis mission to land astronauts on the moon by 2024: It's a crucial way to study the moon itself and to pave a safe path to Mars. But it's also a great place to learn more about protecting Earth, which is just one part of the larger Sun-Earth system.
Scientists find way to quantify how well cutting-edge microscopy technique works
In 2017, Salk scientists reported that tilting a frozen protein sample as it sat under an electron microscope was an effective approach to acquiring better information about its structure and helping researchers understand a host of diseases ranging from HIV to cancer. Now, they have developed a mathematical framework that underlies some of those initial observations.
Molecular hydrogen becomes semimetallic at pressures above 350 GPa
According to condensed matter physics predictions, at a high enough pressure, hydrogen should dissociate and transform into an atomic metal. However, the exact pressure range at which this occurs has not yet been ascertained, and the process through which hydrogen becomes a metal is still somewhat unclear.
New research into Tasmanian Aboriginal history will help care for the land
American farmer and poet Wendell Berry said of the first Europeans in North America that they came with vision, but not with sight. They came with vision of former places but not the sight to see what was before them. Instead of adapting their vision to suit the place, they changed the landscape to fit their vision.

Breakthrough research leads to new product that forecasts long-term drought
Recently published climate research led by Sanjiv Kumar, a professor in Auburn University's School of Forestry and Wildlife Sciences, has already provided the basis of a pioneering new outlook product that is capable of forecasting drought.
Shape of volcanic ash influences contamination of water sources in volcanically active regions
Contaminants from volcanic eruptions leach into water at different rates depending on the shape of the volcanic ash particles, according to new research that could enhancing scientists' ability to predict water quality risk in volcanically active regions.
The mass inflow and outflow rates of the Milky Way
According to the most widely accepted cosmological models, the first galaxies began to form between 13 and 14 billion years ago. Over the course of the next billion years, the cosmic structures now observed first emerged. These include things like galaxy clusters, superclusters and filaments, but also galactic features like globular clusters, galactic bulges, and supermassive black holes (SMBHs).
Global bank urges cities to invest in new infrastructure to adapt to climate change
The impacts of climate change on weather, sea levels, food and water supplies should be seen as an investment opportunity for our cities, says global investment banking firm Goldman Sachs.
Britain is a nation of pet lovers—and it has the Victorians to thank
Britain was the first country in the world to start a welfare charity for animals, as early as 1824. Now, almost 20m cats and dogs have a loving place in the country's homes, and almost one in two households is accompanied by a furry, scaly, or feathered friend.
Hurricane Sandy may have worsened gentrification in Brooklyn and Queens
In New York City alone, Superstorm Sandy killed 44 people, flooded 17 percent of the city's land, uprooted trees, collapsed houses, ran ships aground, deluged subway stations, and blew up power lines. And the impact it has had on the city's housing may go beyond the $19 billion in property damage it caused; the 2012 storm may have exacerbated gentrification's potency in some of the neighborhoods...
Triggering morel fruiting
Morels are economically, culturally, and ecologically important fungi, widely prized as a culinary delicacy, but also because they influence geochemical cycling in forest ecosystems. By deciphering the fruiting-related decomposition mechanisms of morel with multi-omic approaches, the results revealed a striking capability of morel mycelium to acquire carbon from lignocellulosic-abundant matters...

New research suggests we might be thinking about the ocean plastic problem all wrong — trash dumped from ships could be a major culprit
Up to 14 million tons of plastic enters the ocean annually. A study shows that dumping from ships may be the source of a lot of that...
Dealing a therapeutic counterblow to traumatic brain injury

A team of biomedical engineers are developing a therapy which shows early indications it can protect neurons and stimulate the regrowth of blood vessels in damaged tissue.
Scientists create brain-mimicking environment to grow 3D tissue models of brain tumors
- ScienceDaily
- 19/10/4 13:49
Researchers have developed 3-dimensional human tissue culture models of pediatric and adult brain cancers in a brain-mimicking microenvironment, that includes brain-derived extracellular matrix (ECM) -- the complex network of proteins and amino acids with bound sugars that not only provides support for surrounding neural tissue, but also helps to guide cell growth and development. The development...
Long-term study data shows DBS is effective treatment for most severe form of depression
- ScienceDaily
- 19/10/4 13:49
Deep brain stimulation (DBS) of an area in the brain called the subcallosal cingulate (SCC) provides a robust antidepressant effect that is sustained over a long period of time in patients with treatment-resistant depression -- the most severely depressed patients who have not responded to other treatments.

Chemists have found that deliquescent minerals, which dissolve in water they absorb from humid air, can assist the construction of proteins from simpler building blocks during cycles timed to mimic day and night on the early Earth.
Scientists ID new targets to treat fibrosis, a feature of many chronic diseases
- ScienceDaily
- 19/10/4 13:48
When it comes to repairing injured tissue, specialized cells in the body known as fibroblasts are called into action. Fibroblasts give rise to healing cells called myofibroblasts, which generally is good in the short term -- but bad when myofibroblast activation gets out of hand. Now, researchers show how fibroblast activation and myofibroblast formation occurs, providing clues for how to target...

- ScienceDaily
- 19/10/4 13:48
By scanning whole brains of Alzheimer's model mice from an early age, researchers were able to precisely trace the terrible march of amyloid plaques from deep brain structures outward along specific circuits. They also showed that plaque density in a key region in humans scales with disease stage.
A new way to corrosion-proof thin atomic sheets
A variety of two-dimensional materials that have promising properties for optical, electronic, or optoelectronic applications have been held back by the fact that they quickly degrade when exposed to oxygen and water vapor. The protective coatings developed thus far have proven to be expensive and toxic, and cannot be taken off.
Artificial gut aims to expose the elusive microbiome
The microbiome is a collection of trillions of bacteria that reside in and on our bodies. Each person's microbiome is unique—just like a fingerprint—and researchers are finding more and more ways in which it impacts our health and daily lives. One example involves an apparent link between the brain and the bacteria in the gut. This brain-gut "axis" is believed to influence conditions such as...
