The strangest mushroom on Earth keeps making people see the same tiny elves - BBC Science Focus Magazine

A disease that has troubled white button mushroom growers for more than 100 years is far more complicated than scientists previously believed. Researchers at the University of Florida have discovered that the problem involves a surprisingly diverse collection of harmful bacteria, rather than a single pathogen. The finding could help explain why the disease has been so difficult to control and lead to more effective ways to protect mushroom crops. The discovery comes from a University of Florida study investigating bacterial blotch, a persistent disease that damages white button mushrooms and causes significant financial losses for growers.

You taste a bowl of soup and reach for the salt. A little more might bring the flavor together. But what if the same amount of salt could deliver a stronger salty taste? Scientists in China have found three tiny fragments of mushroom proteins that did just that in laboratory tests. Added to salt solutions, the molecules made them taste saltier, with the strongest increasing perceived saltiness by about 71 percent. The discovery could help researchers develop seasonings that preserve salty flavor while allowing less sodium. The study in npj Science of Food, led by researchers at Gannan Medical University and Shanxi Medical University, tested peptides from the edible beech mushroom (Hypsizygus marmoreus). Peptides are short chains of amino acids, the building blocks of proteins. Some have tastes of their own, including umami, the savory quality associated with mushrooms and other foods. Certain umami peptides can also strengthen the perception of saltiness. That makes them interesting candidates for a familiar problem: reducing salt can change the taste of food, making a healthier formulation harder to enjoy.

The James Webb Space Telescope has captured an image of a planet orbiting a star 60 lightyears away, that astronomers say is one of the strangest they've ever seen. The exoplanet, 14 Herculis c, is one of two known worlds orbiting star 14 Herculis, and is the coldest exoplanet ever imaged to date.

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.
