Spirituality linked with better health outcomes, patient care

Posted: 12 Jul 2022 11:13 AM PDT

The study is the most rigorous and comprehensive analysis to date of scientific literature on health and spirituality. Overlooking spirituality in health care leaves patients feeling disconnected from the health care system and from the clinicians caring for them. Asking about a patient's spirituality should be part of patient-centered, value-sensitive care, new research suggests.

Space rocket junk could have deadly consequences unless governments act

Posted: 12 Jul 2022 11:13 AM PDT

The re-entry of abandoned stages of rockets left in orbit from space launches have a six to 10 per cent chance of severely injuring or killing a human being in the next decade, according to a new study. Researchers say governments need to take collective action and mandate that rocket stages are guided safely back to Earth after their use, which could increase the cost of a launch, but potentially save lives.

3D printing nickel single crystals using laser additive manufacturing technology

Posted: 12 Jul 2022 11:12 AM PDT

Engineers have succeeded in fabricating a nickel single crystal with only a very few crystalline defects by irradiating nickel powder with a large-radius, flat-top laser beam (i.e., a laser beam whose intensity is uniform across a cross-section of the beam). This technique may be used to fabricate a wide variety of single-crystalline materials, including heat-resistant materials for jet engines and gas turbines.

Shift work increases the severity of strokes later in life

Posted: 12 Jul 2022 11:12 AM PDT

As most Americans wind down for bed, 15 million people are just clocking into work. These hospital workers, emergency responders, factory operators and others are among the 20 percent of the world's population who do shift work. Their different sleep-wake cycle elevates their risk for numerous health disorders, including diabetes, heart attacks, cancer and strokes.

Protein folding in times of oxygen deficiency

Posted: 12 Jul 2022 11:12 AM PDT

Protein molecules require a defined shape in order to function. When they are created, their building blocks are therefore linked together in a very specific way. Researchers are now taking a closer look at a key step in this process and are investigating the effects of transient oxygen starvation on protein folding in plants.

Two different white blood cell types play opposing roles in affecting heartbeat irregularities after heart attack

Posted: 12 Jul 2022 11:12 AM PDT

New research reveals that two different white blood cell types influence cardiac arrhythmia, suggesting that treatments that influence these cells may help reduce patients' risk of sudden cardiac death.

Experience required: A role for vision in the development of inhibitory networks

Posted: 12 Jul 2022 11:12 AM PDT

New research demonstrates that inhibitory and excitatory neuronal circuits of the visual system develop through different processes, even if the organization of the mature circuit is similar. These findings highlight the importance of the continued study of the development of these two systems, the understanding of which is fundamental to comprehending neurodevelopmental disorders.

How do cells react to micro- and nanoplastics?

Posted: 12 Jul 2022 07:27 AM PDT

The smaller plastic particles are, the more easily they can be taken up by cells. In addition, the shape, surface and chemical properties play an important role in answering the question of how the particles could affect human tissue, according to new research.

New research provides insight into Long COVID and ME

Posted: 12 Jul 2022 07:27 AM PDT

During sleep the brain's reaction to sound remains strong, but one critical feature of conscious attention disappears

Posted: 12 Jul 2022 07:26 AM PDT

New research may provide a key to a scientific enigma: How does the awake brain transform sensory input into a conscious experience? The groundbreaking study relied on data collected from electrodes implanted, for medical purposes, deep in the human brain. The information was utilized to examine differences between the response of the cerebral cortex to sounds in sleep vs. wakefulness, at a resolution of single neurons.

Economic inequality and instability impact long-term decision-making around the world, study finds

Posted: 12 Jul 2022 07:26 AM PDT

A large study involving more than 60 countries finds that individuals across income groups and locations often prefer immediate gains at the expense of future gains, a phenomenon known as temporal discounting. However, greater individual economic resources and living in a stable and more equal economy make the behavior less likely.

Sperm are masters of DNA packing

Posted: 11 Jul 2022 11:32 AM PDT

During sperm production, an enormous amount of DNA has to be packed into a very small space without breaking anything. A central role is played by certain proteins around which the DNA thread is wrapped -- the protamines. A recent study provides new insights into this important mechanism.

Could a phytochemical derived from vegetables like broccoli be the answer to antibiotic resistant pathogens?

Posted: 11 Jul 2022 10:53 AM PDT

While more and more pathogens have developed biofilms that protect them from being eradicated by antibiotics, fewer classes of antibiotics are being developed. Researchers decided to go in a different direction and investigated a phytochemical derived from cruciferous vegetables such as broccoli that breaks down the biofilm.
