New research quantifies the 'wow' factor of sunrise and sunset
- ScienceDaily
- 23/1/19 17:27
A new study has identified the impact that fleeting natural events, such as sunrises and sunsets, can have on people, and sought to quantify their effects. Researchers used the latest computer graphics to show carefully controlled images of both urban and natural environments to more than 2,500 participants. When these scenes featured elements such as sunrise and sunset, participants considered...
Active matter theory explains fire-ant group behavior
- ScienceDaily
- 23/1/19 17:27
Ants are social insects and the Solenopsis invicta species -- known as the fire ant -- is no exception. The social interactions of this invasive insect, which comes from South America, are framed within the context of the theory of Active Matter, which would explain the ants' group behavior as a reaction to the intrinsic mechanisms in the system.

Scientists reveal how a methane-generating microbe can grow on toxic sulfite without becoming poisoned.
'Living medicine' created to tackle drug-resistant lung infections
- ScienceDaily
- 23/1/19 17:27
Researchers demonstrate that a bacteria can be modified to act as 'living medicine' in the lung. The treatment significantly reduced acute lung infections in mice and doubled their survival rate. It showed no signs of toxicity in the lungs and once the treatment had finished its course, it was cleared by the immune system in a period of four days. The treatment also cleared biofilms that...
Fashion sneakers propel sustainable rubber in Brazil Amazon
Rubber tapper Raimundo Mendes de Barros prepares to leave his home, surrounded by rainforest, for an errand in the Brazilian Amazon city of Xapuri. He slides his long, scarred, 77-year-old feet into a pair of sneakers made by Veja, a French brand.
Scientists demonstrate quantum recoil for the first time, paving the way for precise X-ray imaging
For the first time since it was proposed more than 80 years ago, scientists from Nanyang Technological University, Singapore (NTU Singapore) have demonstrated the phenomenon of "quantum recoil," which describes how the particle nature of light has a major impact on electrons moving through materials. The research is published online today (January 19) in the journal Nature Photonics.
Loss of tiny organisms hurts ocean, fishing, scientists say
The warming of the waters off the East Coast has come at an invisible, but very steep cost—the loss of microscopic organisms that make up the base of the ocean's food chain.
Warming to make California downpours even wetter, study says
As damaging as it was for more than 32 trillion gallons of rain and snow to fall on California since Christmas, a worst-case global warming scenario could juice up similar future downpours by one-third by the middle of this century, a new study says.
Carbon capture: how does CO2 removal work?
With global temperatures still on the rise, even the most sceptical of scientists agree that carbon dioxide removal (CDR) is crucial to meet the Paris Agreement goal of capping global warming below two degrees Celsius.
Effective and reusable tandem catalyst developed for plastic waste conversion
The rapid growth of plastic waste is an ever-growing environmental and energy challenge. Selectively converting waste plastics to naphtha, a main feedstock for ethylene and the plastic industry, shows high potential to partially replace petroleum-route naphtha and alleviate global net carbon emissions.
Researchers develop organic, air-stable, highly conducting neutral molecular crystal with unique electronic properties
In an unprecedented feat, researchers from Japan have developed an organic, air-stable, highly conducting neutral molecular crystal with unique electronic properties.
Evolutionary loss of a ryanodine receptor isoform appears to explain how resting muscles produce heat
A team of researchers from the University of Queensland, La Trobe University and Monash University, all in Australia, has found evidence that suggests the evolutionary loss of a ryanodine receptor isoform may explain how muscles in warm-blooded creatures evolved to allow for the generation of heat even when at rest. The paper is published in Proceedings of the National Academy of Sciences.
Thousands at risk of heart attacks due to Covid disruption, experts warn
Patients in England, Scotland and Wales missed out on starting blood pressure-lowering drugs, British Heart Foundation saysThousands of people are at risk of avoidable heart attacks and strokes, experts have warned, after nearly 500,000 people in England, Scotland and Wales missed out on starting blood pressure-lowering drugs during the pandemic.Researchers said that thousands of people could...
GM bacteria could combat antibiotic resistance, study suggests
Re-engineered bacteria able to target drug-resistant infections in mice, research findsGenetically modified bacteria could be used to treat intractable lung infections, according to research aiming to combat the threat of antibiotic resistance.The research, in mice, showed that a re-engineered bacteria could be used to target drug-resistant infections and make them susceptible to antibiotics that...
Researchers cover thousands of years in a quest to understand the elusive origins of the Black Death
Seeking to better understand more about the origins and movement of bubonic plague, in ancient and contemporary times, researchers at McMaster University, University of Sydney and the University of Melbourne, have completed a painstaking granular examination of hundreds of modern and ancient genome sequences, creating the largest analysis of its kind.
Anti-Asian discrimination cost Chinese restaurants $7.4 billion during the pandemic's first year, new study finds
At the onset of the COVID-19 pandemic, anti-China fervor stoked consumer discrimination that cost Chinese restaurants $7.4 billion in lost revenue in 2020—losses 18.4 percent greater than at other types of restaurants—according to a new study by researchers from Boston College, the University of Michigan, and Microsoft Research, published today in the journal Nature Human Behaviour.
How supermassive fuel-hungry black holes feed off intergalactic gas
Research led by the University of Southampton has revealed how supermassive black holes (SMBHs) are feeding off gas clouds which reach them by traveling hundreds of thousands of light years from one galaxy to another.
Malformed seashells, ancient sediment provide clues about Earth's past
Nearly 100 million years ago, the Earth experienced an extreme environmental disruption that choked oxygen from the oceans and led to elevated marine extinction levels that affected the entire globe.
A magnetic method to clean PFAS contaminated water
Researchers at The University of Queensland have pioneered a simple, fast and effective technique to remove PFAS chemicals from water.
Study sheds light on how human activities shape global forest structure
Climate change and human activities strongly influence forests, but researchers have not fully understood the pervasiveness of these stressors and how they will shape future forest structure.
Researchers decipher comprehensive black-legged tick genome
A University of Maryland-led team of scientists has deciphered the first comprehensive, continuous genome for a parasite responsible for transmitting Lyme disease and other serious infections to hundreds of thousands of Americans yearly. With their newly described genome for the black-legged tick, or deer tick, the researchers identified thousands of novel genes and new protein functions,...
