Air pollution major risk for cardiovascular disease regardless of country income
- ScienceDaily
- 20/6/23 20:54
From low-income countries to high-income countries, long-term exposure to fine particulate outdoor air pollution is a major contributor to cardiovascular disease and death, a new study found. But even small reductions in air pollution levels can result in a reduction of disease risk.
Slow-growing rotavirus mutant reveals early steps of viral assembly
- ScienceDaily
- 20/6/23 20:53
Rotavirus is responsible for more than 130,000 deaths in infants and young children younger than five years, every year. The virus causes severe, dehydrating diarrhea as it replicates in viral factories called viroplasms that form inside infected cells. Viroplasms have been difficult to study because they normally form very quickly, but a serendipitous observation led researchers to uncover new...

- ScienceDaily
- 20/6/23 20:53
A new study of 100 mobile apps for kids found that 72 violated a federal law aimed at protecting children's online privacy. Researchers developed a tool that can determine whether an Android game or other mobile app complies with the federal Children's Online Privacy Protection Act (COPPA).
Does 'mommy brain' last? Study shows motherhood does not diminish attention
- ScienceDaily
- 20/6/23 20:53
'Mommy brain' is a long-held perception that mothers are more forgetful and less attentive. A new study shows that mothers are equally as attentive, or more attentive than, non-mothers.
Universal flu vaccine may be more challenging than expected
- ScienceDaily
- 20/6/23 20:53
Some common strains of influenza have the potential to mutate to evade broad-acting antibodies that could be elicited by a universal flu vaccine, according to a new study. The findings highlight the challenges involved in designing such a vaccine, and should be useful in guiding its development.

- 20/6/23 20:53
A navigation algorithm enables drones to learn challenging acrobatic maneuvers. Autonomous quadcopters can be trained using simulations to increase their speed, agility and efficiency, which benefits conventional search and rescue operations.
Size matters in the sex life of salmon
- ScienceDaily
- 20/6/23 20:53
For Atlantic salmon, size matters when it comes to love. Larger males and females that may spend up to four years at sea produce many more babies, but they are very rare compared to younger fish.
Gear treated with 'forever chemicals' poses risk to firefighters
- ScienceDaily
- 20/6/23 20:53
Researchers tested more than 30 samples of used and unused PPE from six specialty textile manufacturers in the United States and found them to be treated extensively with PFAS or constructed with fluoropolymers, a type of PFAS used to make textiles oil and water resistant.
Bedtime media use linked to less sleep in children who struggle to self-regulate behavior
- ScienceDaily
- 20/6/23 20:53
Researchers followed 547 children for a week and measured their media use and sleep patterns. For children who generally struggle to self-regulate their behavior, screen time in the hour before bed was associated with less sleep. Media use in children who scored high on measures of effortful control was not related to less sleep.
Research determines financial benefit from driving electric vehicles
- ScienceDaily
- 20/6/23 20:53
Motorists can save as much as $14,500 on fuel costs over 15 years by driving an electric vehicle instead of a similar one fueled by gasoline, according to a new analysis.
Airborne mapping sheds light on climate sensitivity of California redwoods
- ScienceDaily
- 20/6/23 20:53
To better understand redwood habitat suitability, a team of researchers combined high-resolution redwood distribution maps with data on moisture availability to identify the environmental factors that shape redwood distribution.
Tropical forest loss is increased by large-scale land acquisitions
- ScienceDaily
- 20/6/23 20:53
A new study finds that tropical forest loss is increased by large-scale land acquisitions and that certain kind investment projects -- including tree plantations and plantations for producing palm oil and wood fiber -- are ''consistently associated with increased forest loss.''
Three-quarters of US workers can't work exclusively from home, face greater risks during pandemic
- ScienceDaily
- 20/6/23 20:53
About three-quarters of US workers, or 108 million people, are in jobs that cannot be done from home during a pandemic, putting these workers at increased risk of exposure to disease. This majority of workers are also at higher risk for other job disruptions such as layoffs, furloughs or hours reductions, a new study shows.
Mystery astronomical object in 'mass gap': Neutron star? Black hole?
- ScienceDaily
- 20/6/23 20:53
Researchers have discovered what is either the heaviest known neutron star, or the lightest black hole.
Hot ring produces microwave-powered ultrasound pulses wirelessly
- ScienceDaily
- 20/6/23 20:53
Scientists have developed a wireless ultrasound transducer that is efficiently excited by microwaves. The result is a simple oil-filled patch that can be placed anywhere on the body.
Scientists use protein, RNA to make hollow, spherical sacks called vesicles
- ScienceDaily
- 20/6/23 20:53
Using protein and RNA, scientists have created hollow, spherical sacks known as vesicles. These bubble-like entities -- which form spontaneously when specific protein and RNA molecules are mixed in an aqueous buffer solution -- hold potential as biological storage compartments. They could serve as an alternative to traditional vesicles that are made from water-insoluble organic compounds called...
Towards a green future: Efficient laser technique can convert cellulose into biofuel
- ScienceDaily
- 20/6/23 17:13
The plant product cellulose is the most abundant form of biomass globally and can be converted into useful products such as biofuels. However, the processing of this biopolymer is cumbersome, owing to its rigid, water-insoluble structure. To overcome this, scientists recently developed a novel laser-based technique that makes cellulose degradation easier. Because this reaction does not require...
Lack of damage after secondary impacts surprises researchers
- ScienceDaily
- 20/6/23 17:13
When a material is subjected to a shock or blast wave, damage often forms internally through spall fracture, and research is needed to know how these damaged materials respond to subsequent shock waves. Recent experimentation on spall fracture in metals found that, in certain cases, there was an almost complete lack of damage with only a thin band of altered microstructure observed. Researchers...
Venus flytrap snapping mechanisms virtually captured
- ScienceDaily
- 20/6/23 17:13
The Venus flytrap (Dionaea muscipula) takes only 100 milliseconds to trap its prey. Once their leaves, which have been transformed into snap traps, have closed, insects can no longer escape. Using biomechanical experiments and virtual Venus flytraps a team has analyzed in detail how the lobes of the trap move.
Getting real with immersive sword fights
- ScienceDaily
- 20/6/23 17:13
Sword fights are often the weak link in virtual reality (VR) fighting games, with digital avatars engaging in battle using imprecise, pre-recorded movements that barely reflect the player's actions or intentions. Now a team has found a solution to the challenges of creating realistic VR sword fights: Touche - a data-driven computer model based on machine learning.
