Grid reliability under climate change may require more power generation capacity

Researchers applied a new modeling approach for long-term planning of the U.S. power grid under future climate and water resource conditions. The new approach shows the grid may need an additional 5.3% to 12% of power-generating capacity to meet demand and reliability requirements. The changes would lower water use and carbon emissions, potentially helping mitigate future climate changes.

Almost a third of tropical Africa's flora faces extinction

31.7% of tropical Africa's vascular plant species could be threatened with extinction, reveals an international study. Using a new approach based on the key elements of the assessment process used by the International Union for Conservation of Nature (IUCN), for the first time researchers have been able to assess the potential conservation status of tropical flora on the scale of a continent.

Wolfe Creek Crater younger than previously thought

Wolfe Creek Crater, one of the world's largest meteorite craters, is much younger than previously thought.

First evidence of bio-essential sugars in meteorites

A new study has discovered meteorites containing RNA sugar, ribose, and other bio-important sugars; the first direct evidence of bio-essential sugars' delivery from space to the Earth.

How to fight illegal cocoa farms in Ivory Coast

The world's love for chocolate has helped decimate protected forests in western Africa as some residents have turned protected areas into illegal cocoa farms and hunting grounds. But an international group of researchers has found that simply patrolling the grounds of two forest reserves in Ivory Coast has helped reduce illegal activity by well more than half between 2012 and 2016.

Clay as a feed supplement in dairy cattle has multiple benefits

Dairy producers frequently add clay as a feed supplement to reduce the symptoms of aflatoxin and subacute ruminal acidosis (SARA) in lactating cows. In a new study, researchers show that clay can also improve the degradability of feedstuffs.

Smart buildings face challenges but have plenty of potential

Scientists have examined the concepts of occupant-centric control in the burgeoning field of smart buildings. They propose future directions for OCC research by providing recommendations to address these challenges and to standardize OCC implementations.

Dead-zone report card reflects improving water quality in Chesapeake Bay

The 2019 'dead-zone' report card for Chesapeake Bay indicates that the volume of low-oxygen, 'hypoxic' water was on the high end of the normal range, a finding that scientists consider relatively good news given the unfavorable weather conditions.

When grown right, palm oil can be sustainable

Turning an abandoned pasture into a palm tree plantation can be carbon neutral, according to a new study. These findings, based on measurements of 56-year-old palm tree plantations in Colombia, suggest we may be able to find sustainable alternatives to deforestation for the production of palm oil -- a practice currently under fire by environmentalists.

Researchers design an improved pathway to carbon-neutral plastics

Researchers have designed a new and improved system for efficiently converting CO2, water, and renewable energy into ethylene -- the precursor to a wide range of plastic products -- under neutral conditions.

Emissions from electricity generation lead to premature deaths for some racial groups

Researchers have found that air pollution from electricity generation emissions in 2014 led to about 16,000 premature deaths in the continental US.

How plants handle stress

Plants get stressed too. Drought or too much salt disrupt their physiology. An international research team investigated how evolutionary changes in receptor proteins led to their ability to sense the hormone abscisic acid (ABA). This enabled them to develop mechanisms that aided their colonization of dry land and their response to stress.

Energy research: Economizing on iridium

Iridium is an ideal catalyst for the electrolytic production of hydrogen from water -- but it is extremely expensive. But now a new kind of electrode made of highly porous material does an excellent job with just a hint of iridium.

Yeasts in nectar can stimulate the growth of bee colonies

Researchers have found that the presence of yeasts can alter the chemical composition and thus the nutritional value of nectar for pollinators such as bees. Moreover, the study found that yeasts can even boost bee health and colony fitness.

Bursting the bubble: Revealing tasty genetic secrets of gigantic single-celled creatures

Researchers recently unveiled key information about gene expression in sea grapes, which could help shed light on the evolution of sea grape morphology and help farmers improve cultivation of umi-budo.

Icebergs as a source of nutrients

The importance of icebergs as an important source of nutrients in the polar regions has long been discussed. An international research team has investigated ice samples worldwide. A key result is that only a small part of the glacier ice contaminated with sediment contains large amounts of iron, while the vast majority of clean ice contains very little iron.

This humidity digester breathes in atmospheric water and exhales energy

Integrating a super moisture-absorbent gel with light-active materials, researchers have developed a humidity digester to dry the ambient air while generating energy. The method is a green alternative to air conditioners with a trick -- pulling water out of thin air.

Asking if behavior can be changed on climate crisis

One of the more complex problems facing social psychologists today is whether any intervention can move people to change their behavior about climate change and protecting the environment for the sake of future generations. Now researchers report that an intergenerational reciprocity approach, asking people to reflect on sacrifices made in the past by others for their benefit today, may generate a sense of moral obligation to future generations.
