Reduction of global inequalities in energy use necessary to stop climate change
A new ICTA-UAB study shows that existing climate mitigation scenarios perpetuate inequalities in energy use between the Global North and the Global South long into the future. These scenarios disadvantage the Global South and are therefore politically untenable.
The LHCb experiment leads to the observation of an exotic tetraquark
Over the course of the 20th century, physicists have discovered numerous elementary particles. The largest family of these particles are the so-called hadrons, subatomic particles that take part in strong interactions.
Researchers achieve record entanglement of quantum memories
A network in which data transmission is perfectly secure against hacking? If physicists have their way, this will become reality one day with the help of the quantum mechanical phenomenon known as entanglement. For entangled particles, the rule is: If you measure the state of one of the particles, then you automatically know the state of the other. It makes no difference how far away the entangled...

Steel is one of the strongest materials found on earth and is widely used for construction. But on its own, the durability of steel is poor. Galvanizing steel increases its corrosion resistance, making it more sustainable. Recently, a group of scientists proposed a novel method of multilayer coating to increase the longevity of steel.

Russia's invasion of Ukraine has brought the threat of nuclear warfare to the forefront. But how would modern nuclear detonations impact the world today? A new study published today provides stark information on the global impact of nuclear war.
Opioid prescriptions significantly higher for patients with lifelong disabilities, study finds
- ScienceDaily
- 22/7/7 16:09
People with two pediatric-onset neurodevelopmental disorders are prescribed opioids at a rate up to five times higher than those who do not have those conditions, a new study finds. Researchers say the findings raise concerns over addiction, overdose and mental health issues.

Research has uncovered strong evidence that household overcrowding is a major risk factor for acute rheumatic fever and streptococcal infections of the skin.
Researchers discover brain pathway that helps to explain light's effect on mood
- ScienceDaily

Improved understanding of a neural pathway connecting light-sensitive cells in the retina with the cortical brain regions involved in mood and cognition has implications for the development of treatments for mood disorders.
Climate factors predict future mosquito activity
- ScienceDaily
- 22/7/7 16:09
Increases in three climate factors -- temperature, rainfall, and ocean warming -- predicted mosquito population growth in Sri Lanka for the next one to six months, according to a new study. The findings can inform the design and timing of programs to limit the spread of mosquito-borne diseases like dengue.
Understanding how microbiota thrive in their human hosts
- ScienceDaily
- 22/7/7 16:09
Scientists have made substantial progress in understanding how gut bacteria succeed in their human hosts on a molecular level. They investigated how bacteria produce inositol lipids, substances vital for many cellular processes in humans and other eukaryotes but hitherto rarely observed in bacteria. The results indicate that inositol lipids have implications for the symbiosis between the bacteria...

Research in psychological and brain sciences shows a link in older adults between social interactions and having a sense of purpose.
People who practice intermittent fasting experience less severe complications from COVID-19, study finds
- ScienceDaily
- 22/7/7 16:09
Intermittent fasting has previously shown to have a host of health benefits, including lowering the risk of diabetes and heart disease. Now, researchers have found that people who regularly fast are less like to experience severe complications from COVID-19.
Towards autonomous prediction and synthesis of novel magnetic materials
- ScienceDaily
- 22/7/7 16:09
In materials science, candidates for novel functional materials are usually explored in a trial-and-error fashion through calculations, synthetic methods, and material analysis. However, the approach is time-consuming and requires expertise. Now, researchers have used a data-driven approach to automate the process of predicting new magnetic materials. By combining first-principles calculations,...
Study examines memory in expert birdwatchers
- ScienceDaily
- 22/7/7 16:09
According to a new study that examined memory in expert birdwatchers, having expert knowledge in a subject helps us memorize new information. This is because, while forgetting often happens when similar memories interfere with each other, expert knowledge provides a mental organizational structure, or scaffolding, that helps us keep new items that we want to learn distinct from each other. This...
Unlocking better soil carbon sequestration by studying silicon deposits in plants
Scientists at Oak Ridge National Laboratory are closer to unlocking the secrets to better soil carbon sequestration by studying the tiny, sand-like silicon deposits called phytoliths in plants.
Thin mica shows semiconducting behavior, say scientists in new study
- ScienceDaily
- 22/7/7 16:05
Muscovite mica (MuM) is a highly stable mineral that is commonly used as an insulator. However, the electrical properties of single-layer and few-layered MuM are not well understood. Now, a group of researchers reports and explains unusually high conductivity in MuM flakes that are only a few molecule layers thick. Their findings could open doors to the development of two-dimensional electronic...
Cell map of human gonads identifies the cells involved in sex determination
The first large-scale cellular map of gonadal developmental in both sexes has been created by researchers at the Wellcome Sanger Institute, as part of the Human Cell Atlas initiative to map all cell types in the human body.
Snapping shrimp orbital hood protects against shockwave blasts
A team of researchers from the University of Tulsa and the University of South Carolina, has found that the reason bigclaw snapping shrimp do not suffer from their own shock waves is that they are protected by orbital hoods. In their paper published in the journal Current Biology, the group describes experiments they conducted in their lab that involved removing the hoods from wild shrimp.
Turkish astronomers discover new short-period pulsating variable star
Astronomers from the Istanbul University in Turkey report the finding of a new short-period pulsating variable star during observations of the field of exoplanet host star XO-2. The newly detected object is most likely a Delta Scuti type variable with a pulsation period of less than one hour. The discovery was detailed in a paper published June 29 on arXiv.org.
Taxing animal production to reduce animal density in agriculture
A huge proportion of the world's population is vegetarian, eating no meat for a range of reasons, including lack of availability and poverty, ethical and religious reasons, personal health and environmental health reasons. Among that number are many who are vegan, eating no animal products. However, the environmental impact of raising livestock remains incredibly high; natural ecosystems are...
Removing the nitrogen bottleneck in the world's food supply
A University of Hawaiʻi at Mānoa researcher is a part of a team that developed a synthetic way to transform nitrogen into a bioavailable form that could allow for the production of ammonia fertilizer at a much lower cost and ultimately lead to greater food production across the globe. Though nitrogen is inexhaustible in the atmosphere, scientists say creating enough bioavailable forms of...
