Study uncovers how bacteria use ancient mechanisms to self-repair
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory helped measure how unpaired electrons in atoms at one end of a molecule can drive chemical reactivity on the molecule's opposite side. As described in a paper recently published in the Journal of the American Chemical Society, this work, in collaboration with Princeton University, shows how molecules containing...
Tracking explosions with toughened-up tracers
A new study led by UNSW Sydney scientists unveils how nature's oldest wheel, found within bacteria, can fix itself when times get tough.
New research improves the coolness factor for athletes
What happens in an explosion? Where do the products of that explosion go following the blast? These questions are often difficult to solve. New rugged tracer particles, developed by Pacific Northwest National Laboratory (PNNL) researchers, can provide some answers.
Gully erosion prediction tools can lead to better land management
Weekend joggers, competitive athletes and people keeping fit in the gym can say goodbye to sweaty armpits and clingy damp garments after a tough workout.
Low-cost sensor records the level of rivers
Soil erosion is a significant problem for agricultural production, impacting soil quality and causing pollutants to enter waterways. Among all stages of soil erosion, gully erosion is the most severe phase, where large channels are carved through the field. Once gullies develop, they are challenging to manage through tiling; they require a more comprehensive approach along the impacted area.
Adapting to a hotter planet has never been more important, and progress edged forward at COP27
Researchers at the University of Bonn have developed a method that allows the water level of rivers to be monitored around the clock. The cost-effective sensor is for instance suitable for area-wide flood warning systems. The study has been published in the journal Water Resources Research.
Can we protect Earth from space weather?
As the COP27 climate summit drew to a close over the weekend, it's important to acknowledge that progress was made on climate adaptation—even if more can be done.
NET locus regulates both flavor quality and nutrient metabolite accumulation in rice
In early September 1859, the Northern Lights could suddenly be seen as far south as the Caribbean. The cause was a geomagnetic solar storm—specifically a coronal mass ejection, now dubbed the Carrington Event, after the astronomer who recorded it.
Scientists add 'invisible fiber' to foods for a healthier diet
Rice (Oryza sativa L.) is one of the most important crops worldwide, providing much of the calorific needs for half of the global population. Economic development and rising living standards have led to the demand for rice gradually shifting from satisfying the need to "be full" to satisfying the need to "eat well," and combining flavor with nutrition is essential for the latter. Much research has...
Synthetic fibers discovered in Antarctic air, seawater, sediment and sea ice
Scientists have converted native starches such as wheat, corn and cassava to dietary fiber that can be added to food to make it healthier without changing its texture, color or taste.
Old World flycatchers' family tree mapped
As nations meet in Uruguay to negotiate a new Global Plastics Treaty, marine and forensic scientists publish new results this week that reveal the discovery of synthetic plastic fibers in air, seawater, sediment and sea ice sampled in the Antarctic Weddell Sea. The field research was undertaken during an expedition to discover Sir Ernest Shackleton's ship, the Endurance. The results are published...
New technology maps movement of microscopic algae in unprecedented detail
The European robin's closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance. This is confirmed by a new study of the Old World flycatcher family, to which these birds belong. The study comprises 92 percent of the more than 300 species in this family.
Do acquisitions harm the acquired brand? Identifying conditions that reduce the negative effect
The movement patterns of microscopic algae can be mapped in greater detail than ever before, giving new insights into ocean health, thanks to new technology developed at the University of Exeter.
Surveys reveals five patterns in consumer responses to inflation
Researchers from University of Leeds, University of Vienna, and University of Pennsylvania published a new Journal of Marketing article that examines why consumers develop negative reactions towards acquired brands and explains conditions that attenuate that negative effect.
Concerns raised over aspects of well-being for primary school pupils in England as resilience levels decline
People are scaling back their spending habits and changing attitudes toward saving and borrowing after a year and a half of high inflation, according to a special report from the University of Michigan's Surveys of Consumers.
Egyptian lagoon vital to Cyprus turtles, study shows
Aspects of school well-being of primary school children have been highlighted as a concern in a new report of 21,000 Key Stage 2 primary school pupils in England by RS Assessment from Hodder Education, SchoolDash and Nottingham Trent University.
Machine learning tools autonomously classify 1,000 supernovae
The number of green turtles breeding in Cyprus has risen in recent years—but this bounce-back depends heavily on an Egyptian lagoon where many turtles feed, new research shows.
Mathematicians resolve a longstanding open problem for the so-called 3D Euler singularity
Astronomers at Caltech have used a machine learning algorithm to classify 1,000 supernovae completely autonomously. The algorithm was applied to data captured by the Zwicky Transient Facility, or ZTF, a sky survey instrument based at Caltech's Palomar Observatory.
NASA's Europa Clipper gets its wheels for traveling in deep space
The motion of fluids in nature, including the flow of water in our oceans, the formation of tornadoes in our atmosphere, and the flux of air surrounding airplanes, have long been described and simulated by what are known as the Navier–Stokes equations.
State of the climate: What Australians need to know about major new report
The enormous spacecraft that will head to Jupiter's moon Europa uses four large reaction wheels to help keep it oriented.
They might not have a spine, but invertebrates are the backbone of our ecosystems. Let's help them out
The latest State of the Climate report is out, and there's not much good news for Australians.
Pocket feature shared by deadly coronaviruses could lead to pan-coronavirus antiviral treatment
Many of Australia's natural places are in a poor state. While important work is being done to protect particular species, we must also take a broader approach to returning entire ecosystems to their former glory— a strategy known as "rewilding".
WHO’s departing chief scientist regrets errors in debate over whether SARS-CoV-2 spreads through air
Scientists have discovered why some coronaviruses are more likely to cause severe disease, which has remained a mystery until now. Researchers of the University of Bristol-led study, published in Science Advances today (November 23), say their findings could lead to the development of a pan-coronavirus treatment to defeat all coronaviruses—from the 2002 SARS-CoV outbreak to omicron, the current...

Opinion: The criminal justice system is retraumatizing victims of violent crime
Last week, Indian pediatrician Soumya Swaminathan
announced on Twitter
that she is leaving her post as chief scientist at the World Health Organization (WHO) at the end of this month. She plans to return to India to work on public health there.
Swaminathan, 63, joined WHO in 2017 and in March 2019 was named the agency’s first chief scientist, a position created...
In a split moment, violence can change our lives. We could become a target of violence in our home, school, workplace and community. You might be slapped, punched, stabbed or shot, resulting in serious injuries, trauma or even death.
