For Plasma with a Hot Core and Cool Edges, Super-H Mode Shows Promise

Fusion reactors face a challenge called “core-edge integration,” which involves maintaining a plasma that is hot at the core but not too hot to damage reactor walls. New research finds that a previously identified operating regime called Super H-mode can leverage the use of impurities such as nitrogen to address this challenge. The research also indicates that Super-H mode can be scaled up to future fusion plants.

The Voting Rights Act Increased Racial Economic Equality That’s Now Diminishing

As many state legislatures consider weakening voter protections and Congress debates new voting rights laws, recent research from the University of California San Diego’s Rady School of Management reveals that the 1965 Voting Rights Act contributed to improvements of the economic status of Blacks. Conversely, after the Supreme Court rendered the Voting Rights Act ineffective in 2013, it led to economic disenfranchisement for Black families that continues to persist.

Many Historically “Redlined” California Communities Have Higher COVID-19 Incidence and Mortality

One of the legacies of “redlining” may be higher incidence and mortality rates of COVID-19 affecting the largely minority and poor residents of these neighborhoods, according to research published at the ATS 2022 international conference. ” Redlining is a Great Depression-era federal policy in which neighborhoods with large ethnic/racial minority groups were denied federal resources.

Scientists See Signs of Traumatic Brain Injury in Headbutting Muskox

Scientists at the Icahn School of Medicine at Mount Sinai saw for the first time hallmarks of concussions and other head trauma in the brains of deceased headbutting animals—muskoxen and bighorn sheep. The results published in the journal Acta Neuropathologica may contradict the commonly-held belief that ramming animals do not suffer brain injuries and support the notion that studies on animals with brains evolutionarily similar to those of humans may help researchers understand and reduce traumatic brain injuries.

New guideline refines care for brain bleeds: Compression socks, some meds not effective

Some treatments or preventive therapies used to manage intracerebral hemorrhages (ICH), or a bleeding stroke, are not as effective as previously believed, according to the new American Heart Association/American Stroke Association guideline for caring for people with spontaneous ICH, published today in the Association’s Stroke journal. Guidelines detail the latest, evidence-based treatment recommendations and are the Association’s official clinical practice recommendations.

Predictable Home Environment Protects Against Development of Heart Disease Risk Factors After Child Abuse

Studies have demonstrated that exposure to physical and psychological abuse in childhood is associated with cardiovascular risk factors in adulthood, such as high blood pressure, high cholesterol and type 2 diabetes. A new study shows for the first time that well-organized households protect children who have experienced abuse from developing some precursors to heart disease.

Early Results of an International Trial Indicate that Robotic-Assisted Lobectomy is a Cost-Effective Intervention Associated with Better Patient-Reported Health-Related Quality of Life

In comparison to data about video-assisted (VATS) lobectomy, retrospective data about robotic-assisted (RTS) lobectomies show such benefits as decreased postoperative pain, lower mortality, shorter chest tube duration, shorter hospital stays, and reduced incidences of postoperative pulmonary complications.

Sleep Disruption Predicts Drinking and Cannabis use in Young People, with Middle and High School Students Potentially Most Vulnerable

A five-year study has highlighted the importance of healthy sleep patterns in relation to future binge-drinking and cannabis use in adolescence and young adulthood, as reported in Alcoholism: Clinical and Experimental Research. The work builds on growing evidence that sleep characteristics are predictive of future substance use and related problems in young people, and could inform strategies for substance use prevention and intervention. Most previous studies assessed only a small range of sleep characteristics, and had limited follow-up. In the new analysis, researchers used six annual assessments from the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA) study to examine whether multiple sleep characteristics in any year predict alcohol and cannabis use the following year. Data from over eight hundred NCANDA study participants, aged 12 to 21 at baseline, were included.

University of Minnesota technology allows amputees to control a robotic arm with their mind

A team of biomedical engineering researchers and industry collaborators have developed a way to tap into a patient’s brain signals through a neural chip implanted in the arm, effectively reading the patient’s mind and opening the door for less invasive alternatives to brain surgeries.

Early Earth: Tungsten isotopes in seawater provide insights into the co-evolution of Earth’s mantle and continents

In a study published in the journal Nature Communications, Andrea Mundl-Petermeier and Sebastian Viehmann of the Department of Lithospheric Research at the University of Vienna have demonstrated that a new geochemical archive – 182Tungsten in banded iron formations – can be used to simultaneously trace both the evolution of the Earth’s mantle and continents throughout Earth’s history. This offers new opportunities to better understand the Precambrian Earth in the future.

NUS researchers upcycle pineapple leaves into low-cost fat trappers

A team of researchers from the National University of Singapore has created low-cost fat-trapping capsules and crackers using pineapple leaf fibres. These capsules or crackers can absorb fatty compounds (such as animal fats) in the body, and the fat-coated lumps will then be passed out from the digestive system. This novel approach to upcycle agricultural waste can be used for other types of cellulose fibres, such as sugarcane bagasse and coffee grounds.

NAVIGATOR Data Show Half of Patients with Severe, Uncontrolled Asthma Improved with Tezepelumab Therapy

A greater proportion of patients with severe, uncontrolled asthma had more significant clinical responses to tezepelumab than placebo, according to research published at the ATS 2022 international conference. The study showed that nearly half of those enrolled achieved complete response to treatment across measures of exacerbation reduction, asthma control, lung function, and clinician assessment.

إجراء في القلب لتقليل مخاطر السكتة الدماغية يُفترض أن يعالج التسربات الصغيرة

مدينة روتشستر، ولاية مينيسوتا- يعتبر التسرب بعد إغلاق الزائدة الأذينية اليسرى أكثر أهمية مما كان يُعتقد سابقًا، وفقًا لبحث جديد في مايو كلينك. يُظهر هذا البحث أنه حتى التسريبات الصغيرة ترتبط بزيادة بنسبة 10% إلى 15% في مخاطر الأحداث الضارة.

Procedimiento cardíaco para disminuir riesgo de accidente cerebrovascular debe controlar fugas pequeñas

Las fugas después del cierre del apéndice auricular izquierdo son más importantes de lo que se creía, dice un nuevo estudio de Mayo Clinic. El estudio muestra una relación entre una fuga, aunque sea pequeña, y un riesgo entre 10 y 15 por ciento mayor de sufrir un evento adverso.
