Scientists build ‘baby’ wormhole as sci-fi moves closer to fact

WASHINGTON, Nov 30 (Reuters) — In science fiction — think films and TV like “Interstellar” and “Star Trek” — wormholes in the cosmos serve as portals through space and time for spacecraft to traverse unimaginable distances with ease. If only it were that simple.

Scientists have long pursued a deeper understanding of wormholes and now appear to be making progress. Researchers announced on Wednesday that they forged two miniscule simulated black holes — those extraordinarily dense celestial objects with gravity so powerful that not even light can escape — in a quantum computer and transmitted a message between them through what amounted to a tunnel in space-time.

Advances in brain modeling open a path to digital twin approaches for brain medicine

Posted by in categories: biotech/medical, computing, neuroscience

In the current edition of The Lancet Neurology, researchers of the Human Brain Project (HBP) present the novel clinical uses of advanced brain modeling methods. Computational brain modeling techniques that integrate the measured data of a patient have been developed by researchers at AMU Marseille as part of the HBP. The models can be used as predictive tools to virtually test clinical hypotheses and strategies.

To create personalized models, the researchers use a called The Virtual Brain (TVB), which HBP scientist Viktor Jirsa has developed together with collaborators. For each patient, the computational models are created from data of the individually measured anatomy, structural connectivity and brain dynamics.

The approach has been first applied in epilepsy, and a major clinical trial is currently ongoing. The TVB technology enables clinicians to simulate the spread of abnormal activity during in a patient’s brain, helping them to better identify the target areas. In January, the team had presented the detailed methodology of the epilepsy work on the cover of Science Translational Medicine.

Delivering more compassionate care in intensive care medicine

Posted by in categories: biotech/medical, ethics, health

In the intensive care unit (ICU), critically ill patients are cared for by a multidisciplinary care team. Compassionate and caring behaviors on the part of the care team result in better outcomes for patients and their families, and care providers entering the demanding field of medicine because they wish to help people and relieve suffering. However, studies have demonstrated deficiencies in delivering compassionate health care. Evidence suggests that physicians may miss up to 90% of opportunities to respond to patients with compassion.

To determine what factors drive and enhance compassionate care behaviors in the ICU setting and which factors drain and negate caring attitudes and behaviors, Shahla Siddiqui, MD, MSc, FCCM, and a colleague conducted an observational, qualitative study of an international panel of intensive and critical . The researcher-clinicians report in PLOS ONE that while ICU physicians and nurses feel a deep moral imperative to deliver the highest level of compassionate care, pressures of capacity strain, lack of staff, lack of compassionate skills training and a heavy emphasis on electronic health record maintenance present significant hurdles to achieving that goal.

“Studies done on physician compassion from a patient perspective emphasize listening and awareness of the patient’s , which not only builds trust within the patient-physician relationship but also enhances resilience amongst the care team and prevents burnout,” said Siddiqui, an anesthesiologist at BIDMC. “Our aim was to describe compassionate behaviors in the ICU, study the factors that enhance and those that drain such behaviors with an aim to enable recommendations for practice and training.”

How can Europe tackle its unfinished tuberculosis business?

Posted by in categories: biotech/medical, business, economics

In 2015, European countries formulated the Sustainable Development Goals (SDG), which aimed to end TB by 2030. However, in September 2018, global leaders at the first United Nations (UN) General Assembly High-Level Meeting on the Fight Against TB agreed on an ambitious target of eradicating TB by 2022. They strategized that increased access to TB treatment and preventive measures would help achieve their goal quickly. Another measure adopted to progress the TB eradication goal was increasing the funds related to TB research and services.

An uneven progress regarding TB eradication by 2030 was observed in some European regions by the World Health Organization (WHO). Although the majority of Western European countries were on track for TB elimination, Eastern European and Central Asian countries reported a high number of incidences of drug-resistant (DR) TB.

In the European Union/European Economic Area (EU/EEA), TB prevalence is low. Based on the TB surveillance conducted in Europe, out of 30 countries, 24 reported less than 10 TB cases per 100,000 population in 2021. These countries have been encouraged to maintain this low rate and attain the pre-elimination phase of less than 10 TB cases per million population per year. A recent Eurosurveillance journal editorial discussed the progress in the EU/EEA, between 2018 and 2021, towards achieving the 2030 targets for TB elimination.

Shh! Intensive care incubators resonate sounds and risk damage to premature babies’ hearing, scientists say

Posted by in category: futurism

For vulnerable premature babies, an incubator in the neonatal intensive care unit (NICU) is a lifesaver, but the consequences can last a lifetime. Many studies have shown that the NICU is a noisy environment and that babies who spend time there have higher rates of hearing impairment, which can lead to delays in language acquisition. Scientists from Vienna, Hamburg, Munich, and Osnabruck set out to investigate the role of the incubator, an underestimated element in the soundscape that surrounds babies during their time in the NICU.

“The motivation of our multidisciplinary research team concerns the question: why many more premature babies suffer hearing impairments,” said Dr. Christoph Reuter from the University of Vienna, corresponding author of the study published in Frontiers in Pediatrics. “We believe that what we have measured in our studies could be a leading cause. However, to understand how to protect from such levels, precise environment information is needed.”

Premature babies experience noise in incubators very differently to the uterus environment. Amniotic fluid muffles from outside the uterus, and most sounds heard in utero will be , with almost no abrupt noises. By contrast, sounds in incubators are much less muffled with many high-frequency components and abrupt noises. Although recommended noise limits have been established, these are often exceeded, especially when incubators are handled or opened.

A New Field of Computing Powered by Human Brain Cells: “Organoid Intelligence”

Posted by in categories: computing, neuroscience

Johns Hopkins researchers break ground on new field of ‘organoid intelligence’.

According to researchers at Johns Hopkins University, a “biocomputer” powered by human brain cells could be developed within our lifetime. This technology is expected to exponentially expand the capabilities of modern computing and open up new areas of research.

The team’s plan for “organoid intelligence” was outlined in a recent article published in the journal Frontiers in Science.

Scientists figured out how to manipulate ‘quantum light’ for the first time in history

Posted by in categories: particle physics, quantum physics

Manipulating anything in the world of quantum physics is tricky, but now, scientists have managed to manipulate quantum light particles that have a strong relationship with each other. The breakthrough sounds a bit obscure, especially if you aren’t studying quantum mechanics yourself, but it’s a huge success that will be fundamental in how scientists study the quantum realm from here forward.
