Food insecurity and cognitive trajectories in older adults

JAMA Network Open

2023-03-24

(Press-News.org) About The Study: In this study using data from 3,037 community-dwelling Medicare beneficiaries, food insecurity was prevalent and associated with a decline in executive function. Interventions and policies aiming to increase healthy food access or reduce food insecurity should be assessed for their impact on older adults’ cognitive outcome.

Authors: Boeun Kim, Ph.D., M.P.H., R.N., of Johns Hopkins University in Baltimore, is the corresponding author.

More predictable renewable energy could lower costs

2023-03-24

Lower electricity costs for consumers and more reliable clean energy could be some of the benefits of a new study by the University of Adelaide researchers who have examined how predictable solar or wind energy generation is and the impact of it on profits in the electricity market. PhD candidate Sahand Karimi-Arpanahi and Dr Ali Pourmousavi Kani, Senior Lecturer from the University’s School of Electrical and Mechanical Engineering, have looked at different ways of achieving more predictable renewable energy with the ...

Synergistic iron carbide catalysts enable direct conversion of syngas into higher alcohols

2023-03-24

Higher alcohols (C2+ alcohols), which are important raw materials, have been used as the intermediates of valued products. They are also widely applied in various fields of fuel, food, fine chemicals, pharmaceuticals and energy. With the gradual depletion of petroleum resources, the direct synthesis of higher alcohols from syngas has become a sustainable and potential process because of its wide source of raw materials and high atomic utilization. However, the low yield of higher alcohols restricted industrial application. Recently, a research team led by Prof. SUN Jian and Prof. GE Qingjie from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has ...

The “wishbone” charm that restores the hope for bone regeneration

2023-03-24

Researchers from Tokyo Medical and Dental University (TMDU) demonstrate how a polymeric nanoparticle gene delivery system can promote bone formation Tokyo, Japan - Does a “magic bullet” exist in regenerative medicine? Researchers have long wished to design a cutting-edge gene therapy that regenerates tissues damaged by disease or trauma. That wish may come true now that a research team has developed a polymeric gene delivery therapy that promotes new bone formation after traumatic inflammation. In a study published this month in the International Journal of Molecular Sciences, researchers from ...

Get help with integrated weed management

2023-03-24

Pesticide use must be reduced. The EU has set a target to reduce pesticide use by 50% by 2030. Therefore, a strong focus on integrated weed management must be maintained in the coming years. When it comes to weeds, the focus has mainly been on improving the efficacy of pesticides, replacing or complementing them with mechanical treatments in the field. In the last five years, the Horizon 2020 project IWMPraise – Integrated Weed Management: PRActical Implementation and Solutions for Europe has conducted a large number of trials on ...

Photosynthesis: varying roads lead to the reaction center

2023-03-24

LMU chemists use high-precision quantum chemistry to study key elements of super-efficient energy transfer in an important element of photosynthesis. Photosynthesis is the motor of all life on Earth. Complex processes are required for the sunlight-powered conversion of carbon dioxide and water to energy-rich sugar and oxygen. These processes are driven by two protein complexes, photosystems I and II. In photosystem I, sunlight is used with an efficiency of almost 100%. Here a complex network of 288 chlorophylls plays the decisive role. A team led by LMU chemist Regina de Vivie-Riedle has ...

Blind people sense their heartbeats better than sighted

2023-03-24

Blind people are better at sensing their own heartbeats than sighted, shows a study by researchers at Karolinska Institutet in Sweden and Jagiellonian University in Poland. The study indicates that blindness leads to a heightened ability in feeling signals from the inner body. The findings are published in the Journal of Experimental Psychology: General. Thirty-six blind and as many sighted individuals were asked to count their own heartbeats without checking their pulse or touching their body. At the same time, the ...

Increasing education opportunities for girls could help reduce preventable deaths in children under five

2023-03-24

An IIASA study shows that maternal education, and particularly secondary education, plays a significant role in reducing deaths in newborns and children under five years of age in both rural and urban areas of India. Sustainable Development Goal (SDG) 3.2.1. aims to end preventable deaths of newborns and under-five children by 2030. Although significant progress has been made worldwide in this regard with global under-five deaths falling from 12.5 million in 1990 to 5 million in 2020, it is still ...

Designing antennas for 6G V2X (Vehicle to Everything) communication

2023-03-24

Researchers at the Indian Institute of Science (IISc) are working on designing antennas that can empower 6G technology, which is instrumental in realising efficient V2X (Vehicle to Everything) communications. In a recent study, the team, led by Debdeep Sarkar, Assistant Professor at the Department of Electrical Communication Engineering, shows how self-interference in full-duplex communication antennas can be reduced, and consequently the movement of signals across the communication network can be faster and more bandwidth-efficient. Such full-duplex ...

Pathogen mapped for the first time – to understand evolution and potential treatments

2023-03-24

A parasite which has devasting impacts on agriculture and human health is the first pathogen to have its proteins located and mapped within its cells – providing clues to their function and helping to identify potential drug targets. African trypanosomes are parasites transmitted by tsetse flies that cause sleeping sickness in humans (presenting as fever, anaemia and, in serious cases, death) and a similar disease celled nagana in cattle. These parasites have made large areas of Africa unsuitable for ...

Graphene grows – and we can see it

2023-03-24

Graphene is the strongest of all materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the discovery of graphene was awarded the Nobel Prize in Physics in 2010. Yet, many properties of the material and its cousins are still poorly understood – for the simple reason that the atoms they are made up of are very difficult to observe. A team of researchers from the University of Amsterdam and New York University have now ...
