Varroa risk to Tasmanian crop pollination‎

A study by the Tasmanian Institute of Agriculture (TIA) has highlighted the impact Varroa mites will have on crop pollination in Tasmania if the parasitic mites become established in the state. The study was prompted by the spread of Varroa on mainland Australia, which is wreaking havoc on European honeybee colonies. Managed honeybee colonies can be monitored and treated for Varroa by beekeepers, but feral honeybee colonies are unmanaged and likely to be at greater risk if Varroa becomes prevalent in Tasmania.

How to protect your pets from New World screwworm‎

Since the U.S. Department of Agriculture confirmed the first case of New World screwworm (NWS) in the United States on June 3, pet owners and shelters alike have expressed concern about what this might mean for their animals. Because the larvae of the parasitic fly infest wounds and can create significant tissue damage if left untreated, veterinarians are encouraging shelters and pet owners, including those who work with colonies of stray or other unowned animals, to remain vigilant and stay informed, especially because NWS infestations can be easily prevented and treated.

The use of robots can increase productivity in SMEs, but may not boost exports‎

Spanish small and medium-sized enterprises (SMEs) in the manufacturing sector that use robots are more productive, especially those that have fewer workers and are less innovative. However, automation alone does not translate into an increase in exports. Companies' presence in international markets is closely linked to the existence of localization economies in the region. This is the main conclusion of a pioneering study by researchers from the UOC's Faculty of Economics and Business. It is the first analysis of the impact that adopting these technologies has on SMEs, firms with a workforce of 10 to 200 employees, a sector that represents a large part of the Spanish business community.

New probe could help trace Alzheimer's-linked lipids one cell at a time‎

Cells sitting side by side in the same tissues are not identical. Each cell carries its own subtly different chemical signature—a hidden individuality that can reveal how diseases take root and spread. Now, researchers from the University of Osaka have developed a technique sensitive enough to capture this cell-by-cell diversity within tissues with unprecedented precision and stability. Their study is published in the journal Analytical Chemistry.

How economic expectations and political polarization influence fertility rates and the number of marriages‎

The University of Barcelona participated in a study that uses an unexpected change of government in Spain—the Spanish Socialist Workers' Party (PSOE) defeated the PP, against the odds, in the March 2004 general election—to examine whether changes in economic expectations affected births, abortions and marriages.

Catching hydrogen in the act: Tracking the absorption process over time‎

If you're looking for hydrogen on the elemental chart, it won't take you long to find it. It is right there at the beginning, the lightest possible material. One electron, one proton, one neutron. Simple, minimalistic, the Marie Kondo of the elemental chart, but with enormous potential in terms of possible technological applications.

Why some glasses break suddenly while others deform smoothly‎

If a liquid is cooled slowly to its freezing point, it becomes a crystal in which the constituent particles are arranged in an ordered pattern. In contrast, when the liquid is cooled very quickly, the particles are unable to arrange themselves in an ordered fashion, and it becomes glass. Glassy materials are all around us in everyday life. Common examples include window glass, certain metal alloys, polymers, foams, gels and even soft materials like emulsions and colloids.

Satellites are transforming biodiversity monitoring for global nature targets, but major gaps remain‎

A new scientific review outlines how satellites and other remote sensing technologies are increasingly shaping how biodiversity and ecosystem health can be monitored at scale—offering new opportunities for countries reporting under international nature targets, while also underscoring important limitations.
