Scientists offer roadmap for studying link between climate and armed conflict
- ScienceDaily
- 20/7/7 22:01
Climate change -- from rising temperatures and more severe heavy rain, to drought -- is increasing risks for economies, human security, and conflict globally. Scientists are leading an effort to better assess the climate-conflict link to help societies manage the complex risks of increased violence from a changing climate.
Future Texas hurricanes: Fast like Ike or slow like Harvey?
- ScienceDaily
- 20/7/7 22:01
Climate change will intensify winds that steer hurricanes north over Texas in the final 25 years of this century, increasing the odds for fast-moving storms like 2008's Ike compared to slow-movers like 2017's Harvey, according to new research.
Boron nitride destroys PFAS 'forever' chemicals PFOA, GenX
- ScienceDaily
- 20/7/7 22:01
Chemical engineers have discovered a photocatalyst that can destroy 99% of the 'forever' chemical PFOA in laboratory tests on polluted water. Researchers showed the boron nitride catalyst also destroys GenX, a PFOA replacement that's also an environmental problem.
Science behind traditional mezcal-making technique

- 20/7/7 22:01
Researchers reveal for the first time why bubbles are a good gauge of alcohol content in mezcal, a traditional Mexican spirit.
Neurons show distinct styles as they interact with the same muscle partner
- ScienceDaily
- 20/7/7 22:01
A study shows a newfound diversity in how cells talk to the muscle they innervate, revealing that the subclasses of neurons have distinct propensities for change, or 'plasticity'.
Custom nanoparticle regresses tumors when exposed to light

A unique nanoparticle to deliver a localized cancer treatment inhibits tumor growth in mice, according to researchers.
Shock-dissipating fractal cubes could forge high-tech armor
- ScienceDaily
- 20/7/7 20:09
3D printed cubes,with intricate fractal voids efficiently dissipate shockwaves, potentially leading to new types of lightweight armor and materials to better withstand explosions and impacts.
How to tackle climate change, food security and land degradation
- ScienceDaily
- 20/7/7 20:09
How can some of world's biggest problems -- climate change, food security and land degradation -- be tackled simultaneously? Some lesser-known options, such as integrated water management and increasing the organic content of soil, have fewer trade-offs than many well-known options, such as planting trees, according to a new study.
Making a list of all creatures, great and small
- ScienceDaily
- 20/7/7 20:09
A new article outlines a roadmap for creating, for the first time, an agreed list of all the world's species, from mammals and birds to plants, fungi and microbes.
Researchers create air filter that can kill the coronavirus
- ScienceDaily
- 20/7/7 19:42
Researchers have designed a 'catch and kill' air filter that can trap the virus responsible for COVID-19, killing it instantly.
Metabolomics meets genomics to improve patient diagnosis
- ScienceDaily

Researchers have improved their ability to identify the genetic cause of undiagnosed conditions.
Our animal inheritance: Humans perk up their ears, too, when they hear interesting sounds
- ScienceDaily
- 20/7/7 17:33
Many animals move their ears to better focus their attention on a novel sound. That humans also have this capability was not known until now. A research team now has demonstrated that we make minute, unconscious movements of our ears that are directed towards the sound want to focus our attention on. The team discovered this ability by measuring electrical signals in the muscles of the vestigial...
Desk-based jobs may offer protection against poor cognition in later life
- ScienceDaily
- 20/7/7 17:33
People who work in jobs that require less physical activity - typically office and desk-based jobs - are at a lower risk of subsequent poor cognition than those whose work is more physically active, suggests new research.
1.5 billion people will depend on water from mountains
- ScienceDaily
- 20/7/7 17:33
Global water consumption has increased almost fourfold in the past 100 years, and many regions can only meet their water demand thanks to essential contributions from mountain regions. In 30 years, almost a quarter of the world's lowland population will strongly depend on runoff from the mountains. Only sustainable development can ensure the important function of mountain areas as Earth's ''water...
Agriculture - a climate villain? Maybe not!
- ScienceDaily
- 20/7/7 17:33
The UN's Intergovernmental Panel on Climate Change (IPCC) claims that agriculture is one of the main sources of greenhouse gases, and is thus by many observers considered as a climate villain.
Dopamine neurons mull over your options
- ScienceDaily
- 20/7/7 17:33
Researchers have found that dopamine neurons in the brain can represent the decision-making process when making economic choices. As monkeys contemplated whether or not to choose an item, a subset of dopamine neurons transitioned from indicating the item's value to indicating the monkey's ultimate decision. Encoding of the decision into these dopamine neurons happened earlier than it did in other...
Excitation of robust materials
- ScienceDaily
- 20/7/7 17:33
So-called topological materials have special electronic properties, which are very robust against external perturbations. In tungsten ditelluride such a topologically protected state can be ''broken up'' using special laser pulses within picoseconds and thus change its properties. This could be a key requirement for realising extremely fast, optoelectronic switches. For the first time, physicists...

Interplay of impact, moral goals influences charitable giving to different causes
- ScienceDaily
- 20/7/7 17:33
With the rise of globalization, geographic borders are becoming less relevant for making charitable donations, which means nonprofits and charities can make more effective pitches to donors by emphasizing higher-level concepts such as morality and idealistic values, said Carlos Torelli, a professor of business administration and the James F. Towey Faculty Fellow at Illinois.

- ScienceDaily
- 20/7/7 17:32
While researchers have previously identified brain structural signatures associated with individual neurological diseases using techniques such as magnetic resonance imaging (MRI), a team of scientists has now compared data from multiple studies to find brain structural abnormalities shared between four different neuropsychiatric conditions. The researchers also found brain signatures that were...
