This protein slows the aging brain and we know how to counter it

Aging is particularly harsh on the hippocampus — the brain region responsible for learning and memory. Now, researchers at UC San Francisco have identified a protein that’s at the center of this decline. They looked at how the genes and proteins in the hippocampus changed over time in mice and ...

Sensing sour: How SNAP25 powers taste signals and keeps sensory cells alive

SNAP25 enables sour taste perception by supporting both signal transmission and the long-term survival of type III taste cells

The tongue contains numerous taste buds—tiny sensory organs responsible for detecting taste. Taste buds consist of specialized cells that translate chemical stimuli into neural signals. Among them, type II cells, which respond to sweet, umami, and bitter stimuli, utilize channel-based signal ...

Stora Enso’s billion-euro investment in renewable packaging

Europe's most modern consumer board production line inaugurated in Finland

The largest and most modern consumer packaging board production line in Europe was inaugurated in Oulu, Finland. The new line was inaugurated by Prime Minister of Finland Petteri Orpo, Chair of Stora Enso’s Board of Directors Kari Jordan, President and CEO of Stora Enso Hans Sohlström, and Oulu ...

The diamonds that could find cancer

Endoscopic diamond magnetometer for cancer surgery

University of Warwick researchers have built a new diamond-based magnetic field sensor that could be used to better find tumours through tracing magnetic fluid injected in the body. A cancer diagnosis is most problematic when cells from the tumour have metastasised (spread) to other organs. This ...

Using bacteria to sneak viruses into tumors

The bioengineered platform enables a cancer-killing virus to evade the patient’s immune system — and prevents it from spreading throughout the body.

Researchers at Columbia Engineering have built a cancer therapy that makes bacteria and viruses work as a team. In a study published inNature Biomedical Engineering, theSynthetic Biological Systems Labshows how their system hides a virus inside a tumor-seeking bacterium, smuggles it past the ...

Ultrasound could deliver drugs with fewer side effects

The trouble with many drugs is that they go where they shouldn’t, producing unwanted side effects. Psychiatric drugs might cause dissociation, painkillers can induce nausea and chemotherapy often damages healthy cells. Now a team of Stanford Medicine researchers are closing in on a novel ...

Insights into olfactory disorders in Alzheimer's disease

A diminishing sense of smell can be one of the earliest signs of Alzheimer's disease, even before cognitive impairment occurs. Studies by researchers at the DZNE and Ludwig-Maximilians-Universität München (LMU) provide new insights into this phenomenon. According to the study, the brain's immune ...

Reduced genome – flexible performance: How symbiotic bacteria with minimal genetic information support their host

Despite having only a tiny genome, the symbionts of reed beetles can adapt their gene activity flexibly to the developmental stages and ambient temperatures of their hosts

Many insects live in symbiosis with certain species of bacteria. These bacteria make important contributions to their hosts' nutrition, digestion, detoxification, reproduction and defense. Due to their close coexistence with insects, symbionts often lose genes for metabolic products that are also ...

New method loads mRNA into exosomes in 10 minutes—just mix and go

KIST team develops cubosome-based method for loading large therapeutics without damaging exosomes

Exosomes, naturally derived vesicles responsible for intercellular communication, are emerging as next-generation drug delivery systems capable of transporting therapeutics to specific cells. However, their tightly packed, cholesterol-rich membranes make it extremely difficult to encapsulate ...

Innovative treatment for liver tumors: Electrochemotherapy (ECT) at the University Hospital Regensburg

The University Hospital Regensburg (UKR) is setting new standards in the treatment of liver tumors: With electrochemotherapy (ECT), the Institute of Diagnostic Radiology at the UKR offers a promising, gentle and minimally invasive treatment option for patients with primary or secondary liver ...
