Reaching your life goals as a single-celled organism

How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails. A research team has now been able to simulate this process on the computer.

Universal equation for explosive phenomena

Climate change, a pandemic or the coordinated activity of neurons in the brain: In all of these examples, a transition takes place at a certain point from the base state to a new state. Researchers have discovered a universal mathematical structure at these so-called tipping points. It creates the basis for a better understanding of the behavior of networked systems.

TB immune response discovery could significantly reduce disease harm

A pioneering study has discovered the presence of a harmful inflammatory protein in patients with symptomatic tuberculosis (TB). Researchers say, by targeting the IL-17 cytokine, a component produced naturally by the immune system in response to infection, excessive and damaging lung inflammation caused by TB may be significantly reduced to help speed up patient recovery.

Managing children's weight, blood pressure and cholesterol protects brain function mid-life

Having high blood pressure, high cholesterol and/or obesity from childhood through middle age were linked to poorer brain function by middle age. These cardiovascular risk factors were linked with low memory, learning, visual processing, attention span, and reaction and movement time. Strategies to prevent heart disease and stroke should begin in childhood to promote better brain health by middle...

Small study shows heart damage after COVID-19 uncommon in college athletes

In a small study, 82 percent of the college athletes with COVID-19 had symptoms, of which the majority were mild and did not require treatment. Further screening via cardiac MRI of the 4 percent of athletes identified with heart abnormalities found no heart damage or inflammation. All athletes resumed regular training and competition without difficulty after recovering from COVID-19.

Serotonin transporters increase when depression fades

Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells. A brain imaging study now shows that the average level of the serotonin transporter increased in a group of 17 individuals who recovered from depression after cognitive behavioral therapy.

Intersection of 2D materials results in entirely New materials

Physics researchers discover that assembling 2D materials into a 3D arrangement does not just result in 'thicker' 2D materials but instead produces entirely new materials. The nanomesh technologically is simple to produce and offers tunable material properties to meet the demands of future applications. The team's next goal is to use the nanomesh on Silicon (Si) waveguides to develop quantum...

Artificial intelligence makes great microscopes better than ever

Collaboration between deep learning experts and microscopy experts leads to an significantly improved data-intensive light-field microscopy method by using AI and ground-truthing it with light-sheet microscopy. The result is the power of light-field microscopy available to biologists in near real time vs. days or weeks, AND the expansion of biologists' ability to use this microscopy for many...

The legume family tree

The most comprehensive study of the family tree for legumes, the plant family that includes beans, soybeans, peanuts, and many other economically important crop plants, reveals a history of whole-genome duplications.

Why hotter clocks are more accurate

A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping. This is the first time that a measurement has been made of the entropy -- or heat loss -- generated by a minimal clock tens of nanometers thick and 1.5 millimeters long. Understanding the thermodynamic cost involved in timekeeping is a central step along the way in the development of future...

Damage to white matter is linked to worse cognitive outcomes after brain injury

A new study challenges the idea that gray matter (the neurons that form the cerebral cortex) is more important than white matter (the myelin covered axons that physically connect neuronal regions) when it comes to cognitive health and function. The findings may help neurologists better predict the long-term effects of strokes and other forms of traumatic brain injury.

Breaching the blood-brain barrier to deliver precious payloads

RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven't been very useful in treating brain tumors and other brain disease. But a team has shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery...
