Menschen denken in vielen Dimensionen gleichzeitig


Wenn wir unsere Augen öffnen, dann fällt es uns ganz leicht, die verschiedene Objekte, Menschen und Tiere um uns herum zu sehen. Bisher war die weitreichende Forschungsmeinung, dass ein ganz wesentliches Ziel unserer Wahrnehmung ist, Objekte zu erkennen und verschiedenen Kategorien zuzuordnen – zum Beispiel, ob dieses Objekt vor uns ein Hund ist und ob ein Hund zur Kategorie der Tiere zählt. Forschende vom Max-Planck-Institut für Kognitions-und Neurowissenschaften in Leipzig und der Justus-Liebig-Universität Gießen in Zusammenarbeit mit den National Institutes of Health in den USA konnte nun zeigen, dass dieses Bild unvollständig ist. In einer aktuellen Studie im Fachjournal Nature Human Behaviour schreiben sie, dass sich die Hirnaktivität beim Sehen von Objekten viel besser mit einer Vielzahl verhaltensrelevanter Dimensionen erklären lässt.

Bisher dachte man, dass das visuelle System in unserem Gehirn die gesehenen Objekte in sehr grundlegende Merkmale zerlegt und dann nach und nach wieder zusammensetzt, mit dem Ziel, deren Erkennen zu ermöglichen. „Unsere Ergebnisse haben gezeigt, dass Erkennen und Kategorisieren zwar wichtige Ziele unseres Sehens sind, aber bei weitem nicht die einzigen.“, sagt Letztautor Martin Hebart, Gruppenleiter am MPI CBS und Professor an der Justus-Liebig-Universität. „Tatsächlich finden wir verhaltensrelevante Signale an allen Verarbeitungsstufen im visuellen System. Dies konnten wir aus der Analyse der von uns entdeckten verhaltensrelevanten Dimensionen ableiten.” Im Vorfeld hatten die Forscher mit einem Computermodell aus Verhaltensdaten von über 12.000 Studienteilnehmer*innen 66 Objektdimensionen identifiziert.

Finger wrap uses sweat to provide health monitoring at your fingertips

A sweat-powered wearable has the potential to make continuous, personalized health monitoring as effortless as wearing a Band-Aid. Engineers at the University of California San Diego have developed an electronic finger wrap that monitors vital chemical levels—such as glucose, vitamins, and even drugs—present in the same fingertip sweat from which it derives its energy.

The advance was published Sept. 3 in Nature Electronics by the research group of Joseph Wang, a professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at UC San Diego.

The device, which wraps snugly around the finger, draws power from an unlikely source—the fingertip’s . Fingertips, despite their , are among the body’s most prolific sweat producers, each packed with over a thousand . These glands can produce 100 to 1,000 times more sweat than most other areas of the body, even during rest.

Common yellow food dye can make the skin of a mouse temporarily transparent, study finds

In H.G. Wells’ 1,897 science fiction novel, “The Invisible Man,” the protagonist invents a serum that makes the cells in his body transparent by controlling how they bend light.

More than 100 years later, scientists have discovered a real-life version of the substance: A commonly used food coloring can make the skin of a mouse temporarily transparent, allowing scientists to see its organs function, according to a new study published Thursday in the journal Science.

The breakthrough could revolutionize biomedical research and, should it be successfully tested in humans, have wide-ranging applications in medicine and health care, such as making veins more visible to draw blood.

Hospital IT: The Unsung Heroes

IT is the backbone of modern healthcare, from patient records and medication management to diagnostic equipment, networking and communication systems. These healthcare IT professionals play a pivotal role in ensuring the accuracy, security, reliability and accessibility of health data. Hospital IT professionals also ensure that the technological backbones of these hospital systems operate correctly.

They ensure that doctors have real-time access to patient information, nurses can track medication schedules accurately and communication between departments is fluid and efficient. Without this critical support, the efficiency and safety of patient care is severely compromised. Simply put, the work of hospital IT teams is vital to the smooth operation of hospitals.

It is fair and appropriate to say that hospital IT teams are unsung heroes. The nature of working in IT is to keep everything running smoothly at all times. These dedicated, talented and hardworking IT experts are often ignored unless the infrastructure is not working or has failed. Nobody notices when hospital IT systems are operating properly; the IT teams only get noticed when things go wrong, and typically receive negative attention.

How Predictive AI Can Optimize Business Processes In Healthcare

Finally, the goal of any healthcare organization is to provide the best possible care to patients. Predictive AI can contribute significantly to this goal by enabling more accurate diagnoses, tailored treatment plans and earlier interventions.

From the patient’s perspective, this translates to better health outcomes, reduced hospital stays and increased satisfaction with their care. For healthcare organizations, improved patient experiences lead to higher patient retention rates, positive word-of-mouth referrals and better performance on patient satisfaction metrics, which are increasingly tied to reimbursement rates in many healthcare systems.

As we’ve explored, the benefits of predictive AI extend far beyond improved diagnostics and treatment plans. It’s a catalyst for operational excellence, financial optimization, availability of investments and long-term growth. From resource management to building an authoritative brand, predictive AI touches every aspect of the healthcare business environment.

Nucleated synthetic cells with genetically driven intercompartment communication

The brain’s white matter comprises areas of the central nervous system made up of myelinated axons. Its name is derived from the pale appearance of the lipids that comprise myelin. Myelin is a segmented sheath that insulates axons, ensuring the conduction of neural signals. The loss of myelin is documented in a number of neurodegenerative pathologies, including Alzheimer’s and Parkinson’s disease, and perhaps most notably, multiple sclerosis. As people age, demyelination becomes more likely.

Researchers have long suspected a relationship between and the integrity of the brain’s as people age. However, a lack of specific evidence has led researchers at the National Institutes of Health to conduct a study examining the strength of this correlation, now published in the Proceedings of the National Academy of Sciences.

To establish a correlation between cardiovascular fitness and cerebral myelination, the researchers recruited a cohort of 125 participants from age 22 to 94 years old. The cardiovascular fitness of the participants was quantified as the maximum rate of oxygen consumption, popularly and succinctly known as VO2max. Myelin content was defined as the water fraction, which the researchers estimated through an advanced multicomponent relaxometry MRI method.
