Mutually beneficial relationships are common, but what happens when one partner stops enforcing the other’s good behavior? An exception to the usual relationship between figs and their pollinator-wasps, may hold the answer.

Scientists have identified two proteins that could be used for a potential vaccine against nontypeable Haemophilus influenzae (NTHi). Working in a mouse model, the investigators found that administering two bacterial adhesive proteins that play a key r…

Researchers have discovered that a cellular phenomenon called cryptic transcription, which had been previously described and linked to aging in yeasts and worms, is also involved in mammalian aging. They also discovered a mechanism that triggers the ph…

A lush canopy is a defining feature of most of the planet’s forests. But canopy-forming species can be particularly vulnerable to disturbances and environmental change. So the question is: What is a forest without its trees?

Researchers have developed a powerful miniature brain platform to study the mechanistic causes of Alzheimer’s disease and to test dementia drugs in development.

About 2,000 light-years away from Earth, there is a star catapulting toward the edge of the Milky Way. This particular star is one of a unique breed of fast-moving stars — remnant pieces of massive white dwarf stars — that have survived in chunks aft…

For people with diabetes who are insulin dependent, glycemic control is a full-time job. But what if their medication could do the work for them — an insulin whose activity in the bloodstream responds to the blood glucose levels and adjusts accordingl…

When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. Researchers observed such offsets in both eyes of 20 he…

Researchers identify redundant neural networks in jellyfish-like, freshwater hydra. The work is a step toward modeling how internal states and external stimuli shape the behavior of an organism with a highly dynamic neural architecture.

A new treatment for advanced urothelial cancer was effective with tolerable side effects in an international, multi-center phase 2 clinical trial. The trial results prompted a U.S. Food and Drug Administration (FDA) accelerated approval of the treatmen…

The origin and date of appearance of prehistoric cave art are the subjects of ongoing debate. Spain’s Cueva de Ardales is one point of discussion. There a flowstone formation is stained red in places. This coloring is apparently almost 65,000 years old…

Salamanders can navigate complex and unstructured environments thanks to their impressive body-limb coordination. Researchers have built a model that mimics a salamander’s walk with the hope it aids the development of agile and adaptive robots that can…

A vital piece of gas engines, combustors — the chambers in which the combustion powering the engine occurs — have the problem of breaking down due to fatal high-frequency oscillations during the combustion process. Now, through advanced time-series a…

In the latest of ongoing efforts to expand technologies for modifying genes and their expression, researchers have developed chemically modified guide RNAs for a CRISPR system that targets RNA instead of DNA. These chemically-modified guide RNAs signif…

Researchers have now developed a non-invasive method to help diagnose celiac disease and which uses saliva. This research has shown that it is possible to considerably reduce the number of endoscopies, which are currently carried out via a non-invasive…

A long-term hazard from flood water is often underestimated: The raging rivers swirl up pollutants out of their sediments that stem from environmental pollution decades or centuries ago. Such harmful substances can not only cause ecological damage in t…

Researchers have discovered a new method of X-ray imaging based on the coloring abilities of the natural mineral hackmanite. The international group of researchers also found out how and why hackmanite changes color upon exposure to X-rays.

New research demonstrates a metabolic regulatory molecule called Them1 prevents fat burning in cells by blocking access to their fuel source. The study may contribute to the development of a new type of obesity treatment.

Electrical engineers are powering the quantum computing revolution with the development of an on-demand, scalable technique to manipulate nanoscale nanodiamonds.

Among older adults with obesity, combining aerobic exercise with moderate reductions in total daily calories led to greater improvements in vascular health compared to exercise alone. Reducing calorie intake by approximately 250 calories per day may le…
