Parental firearm storage and their teens’ perceived firearm access in US households

About The Study: This study found that parent-reported firearm storage may be a poor estimator of teen perceived firearm access, regardless of teen gender, parental education, and urbanicity. Strictly focusing safety efforts on locked and unloaded firearm storage may not fully negate teen’s perceptions that they can access and load household firearms. Storing additional firearms securely may not prevent teen access if at least 1 household firearm remains unlocked. Corresponding Author: To contact the corresponding author, Katherine G. Hastings, MPH, email katiegh@student.ubc.ca. To access the embargoed study: Visit our For The Media website at this ...

Cryo-EM structures of isovaleryl-CoA dehydrogenase offers new therapeutic strategies for inherited isovaleric acidemia

Background IVD is a key enzyme in leucine catabolism, catalyzing the conversion of isovaleryl-CoA to 3-methylcrotonyl-CoA. Defects in IVD function lead to toxic accumulation of metabolites such as isovaleric acid, resulting in isovaleric acidemia (IVA)—a life-threatening autosomal recessive disorder characterized by vomiting, metabolic acidosis, and neurological damage. Although IVD gene mutations are known to cause IVA, the enzyme's structural dynamics and complex substrate-binding mechanisms have long hindered ...

Kelp forest collapse alters food web and energy dynamics in the Gulf of Maine

While kelp forests persist along northern Maine’s rocky coast, kelp abundance has declined by as much as 80% on the southern coast in recent decades. In its stead, carpet-like turf algae have moved in. A team, led by scientists at Bigelow Laboratory for Ocean Sciences, are examining the broad consequences of this shift. Their recently published research in Science Advances shows that predator-prey interactions and the flow of energy are fundamentally different on turf-dominated reefs compared to the remaining kelp forests. Using ...

Collaboration can unlock Australia’s energy transition without sacrificing natural capital

Decarbonizing Australia’s economy and protecting the country’s most critical natural resources are both possible but will require significant collaboration between energy developers, state and local governments, landowners, and interest groups, according to new research led by Princeton and The University of Queensland. The research, published May 29 in Nature Sustainability, demonstrates that Australia can fully decarbonize its domestic and energy export economies by 2060 while avoiding harm to important areas for biodiversity outcomes, safeguarding agricultural activities, and respecting Indigenous land rights. “The amount ...

Wendelstein 7-X sets new performance records in nuclear fusion research

On the path toward a fusion power plant, stellarators are among the most promising concepts. In the future, they could generate usable energy by fusing light atomic nuclei. This reaction must take place in a plasma — a hot gas of ionized particles heated to many tens of millions of degrees Celsius. Stellarators use magnetic confinement to hold the plasma: the plasma is trapped by a complex and powerful magnetic field, floating inside a donut-shaped vacuum chamber. With Wendelstein 7-X (W7-X), the Max Planck Institute for Plasma Physics (IPP) in Greifswald, with support from the European fusion consortium EUROfusion, is operating the world's ...

Boardroom battles: How corporate coalitions influence firms’ resource allocation

Once organizations achieve their profitability and market performance targets, they often focus on additional goals. However, these goals do not always align and can sometimes conflict. For example, prioritizing shareholder returns may come at the expense of investments in social causes. This raises a critical question: How do companies decide where to allocate their surplus resources and which goals to prioritize? A study published online in the Journal of Business Ethics on May 9, 2025, examines this question by turning the spotlight on the boardroom. A research team consisting of Professor Toru Yoshikawa from the School of Social Sciences, Waseda University, ...

Synthetic molecular rings re-create energy flow found in plants

Plants mastered the art of harvesting sunlight billions of years ago, using elegant rings of pigments in their leaves. Now, researchers from Osaka Metropolitan University have taken a major step toward mimicking that leafy architecture with human-made molecules that self-assemble into stacked rings where charge and energy can circulate freely — just like in photosynthesis. Their design paves the way for new approaches to light capture, energy transport and next-generation electronics. In photosynthetic organisms, pigment molecules form ...

A new approach could fractionate crude oil using much less energy

CAMBRIDGE, MA -- Separating crude oil into products such as gasoline, diesel, and heating oil is an energy-intensive process that accounts for about 6 percent of the world’s CO2 emissions. Most of that energy goes into the heat needed to separate the components by their boiling point. In an advance that could dramatically reduce the amount of energy needed for crude oil fractionation, MIT engineers have developed a membrane that filters the components of crude oil by their molecular size. “This is a whole new way of envisioning a separation process. Instead of boiling mixtures to purify them, why not separate ...

High energy proton accelerator on a table-top — enabled by university class lasers

Laser Ion acceleration uses intense laser flashes to heat electrons of a solid to enormous temperatures and propel these charged particles to extreme speeds. These have recently gained traction for applications in selectively destroying cancerous tumor cells, in processing semiconductor materials, and due to their excellent properties - for imaging and fusion relevant conditions. Massive laser systems with several Joules of light energy are needed to irradiate solids for the purpose. This produces a flash of ions which are accelerated to extreme speeds. Thus, emulating large million volt accelerators is possible ...

World record for lithium-ion conductors

The team led by Prof. Thomas F. Fässler from the Chair of Inorganic Chemistry with a Focus on Novel Materials partially replaced lithium in a lithium antimonide compound with the metal scandium. This creates specific gaps, so-called vacancies, in the crystal lattice of the conductor material. These gaps help the lithium ions to move more easily and faster, resulting in a new world record for ion conductivity. Since the measured conductivity far exceeded that of existing materials, the team collaborated with the Chair of Technical Electrochemistry under Prof. Hubert Gasteiger at TUM to confirm the result. Co-author Tobias Kutsch who conducted the validation tests, commented: “Because ...
