The synthesis and the characterisation of silicon nanowires (SiNWs) have recently attracted great attention due to their potential applications in electronics and photonics. As yet, there are no practical uses of nanowires, except for research purposes, but certain properties and characteristics of nanowires look very promising for the future.
Note from Jay McDaniel: The process tradition is at its best when it resists sectarianism and avoids even the faintest hint of certainty about ultimate metaphysical principles. In this spirit, it welcomes critique—not with reactionary defensiveness, but with deep listening and with the recognition that the critique may, after all, be right. There is no need for combativeness. As Whitehead cautions: “There remains the final reflection, how shallow, puny, and imperfect are efforts to sound the depths in the nature of things. In philosophical discussion, the merest hint of dogmatic certainty as to finality of statement is an exhibition of folly.” (Process and Reality, Preface, xiv.)
Great, but where on earth is the EU in this new space race?
HELSINKI — China is charting a long-term deep space strategy centered on planetary habitability and the search for extraterrestrial life, according to a newly revealed mission roadmap.
A slide titled “habitability and search for extraterrestrial life — guiding the future development of China’s planetary exploration,” was shared on Chinese social media by the country’s Deep Space Exploration Laboratory (DSEL), a national-level research institution under the China National Space Administration (CNSA). It outlines a number of planned and potential missions, many with astrobiological implications.
The first mission is the Tianwen-3 Mars sample return mission, already approved and currently scheduled to launch around late 2028. Among its main objectives is investigating potential traces of past or present life on Mars.
Keloids are fibroproliferative disorders of the skin marked with elevated interleukin-6 and transforming growth factor-beta, causing pain, pruritus, and decreased quality of life.1 Punch excision therapy is emerging as a simple, quick, and accessible treatment option for keloid management. This review summarizes the current evidence on the efficacy and safety of punch excision therapy in keloid management.
Humans and other animals actively sense their surrounding environment. This entails the deliberate adjustment of motor behavior involved in sensory sampling (i.e., movements of the eyes, ears and hands) in line with the stimulus information.
When it comes to the sense of smell, the principal motor behavior that supports active sensing is the sniff, which entails brief inhalations aimed at pulling odor molecules into the nasal cavity. So far, the extent to which sniffing behaviors can be influenced and adapted based on the odors that one is smelling has remained unknown.
Researchers at Northwestern University recently carried out a study aimed at exploring this possibility. Their findings, published in Nature Human Behavior, suggest that people’s sniffing patterns are continuously shaped by what they are smelling and carry detailed information about specific odors.
