Good news, everyone!

Urban trees and plants do more than just beautify city landscapes. They purify the air, reduce urban heat islands, provide recreational spaces, and even boost property values. As essential components of sustainable urban ecosystems, plants silently contribute to our well-being. However, urban trees face many threats, including pests, diseases, and climate change, making it essential to keep their health in check.

When spring arrives and the heating season comes to an end, keeping warm becomes less of an issue. However, scientists remind us that it is not just a seasonal necessity—heat is also a valuable energy resource that can be stored and used when needed most. Researchers at Kaunas University of Technology (KTU) have discovered an innovative solution beneath our feet: using soil as an efficient thermal energy storage system.

One main goal of anti-cancer therapies is to kill tumor cells without affecting the surrounding normal cells. Therefore, many drugs are designed to target tumor-specific antigens, which are molecules only expressed by cancer cells. However, it has proven difficult to identify such specific antigens in certain cancer types, including acute myeloid leukemia (AML).

People living in Bronze Age-era Denmark may have been able to travel to Norway directly over the open sea, according to a study published in PLOS One by Boel Bengtsson from the University of Gothenburg, Sweden, and colleagues.

Single-atom catalysts (SACs), with their excellent metal atom utilization and unique physicochemical properties, hold promise for broad applications, especially in heterogeneous catalysis and energy conversions. Essentially, the activity and stability of SACs are governed by the pair of metal-adsorbate and metal-support interactions. However, the rationale of these interactions with their catalytic performance of SACs in nature and a unified theoretical model to describe both activity and stability remain elusive.

Microsoft celebrates its 50th anniversary. This article was written using Microsoft Word on a computer running Microsoft Windows. It is likely to be published on platforms hosted by Microsoft Azure, including LinkedIn, a Microsoft subsidiary with more than 1 billion users.

Its stock market value is close to $3,000 billion, making it the world's second-most valuable company behind Apple and almost on a par with NVidia. Cumulative profits since 2002 are approaching $640 billion.

Diving beetles (Dytiscidae) maintain the balance of pond ecosystems. They feed on other aquatic organisms, such as mosquito larvae, and form part of the diet of larger animals, including fish, amphibians, and birds. Having such a crucial role in the food chain of ponds, they are a good indicator of biodiversity.
