Infinite sums are among the most underrated yet powerful concepts in mathematics, capable of linking concepts across mathâs vast web.

As our devices get smaller and smaller, the use of molecules as the main components in electronic circuitry is becoming ever more critical. Over the past 10 years, researchers have been trying to use single molecules as conducting wires because of their small scale, distinct electronic characteristics, and high tunability. But in most molecular wires, as the length of the wire increases, the efficiency by which electrons are transmitted across the wire decreases exponentially. This limitation has made it especially challenging to build a long molecular wireâone that is much longer than a nanometerâthat actually conducts electricity well.
Columbia researchers announced that they have built a nanowire that is 2.6 nanometers long, shows an unusual increase in conductance as the wire length increases, and has quasi-metallic properties. Its excellent conductivity holds great promise for the field of molecular electronics, enabling electronic devices to become even tinier.
The study is published in Nature Chemistry (âHighly conducting single-molecule topological insulators based on mono-and di-radical cationsâ).
It could help scientists learn more about memory formation and storage and diseases such as Alzheimerâs.

Metaâs AI translation work could provide a killer app for AR.
Social media conglomerate Meta has created a single AI model capable of translating across 200 different languages, including many not supported by current commercial tools. The company is open-sourcing the project in the hopes that others will build on its work.
The AI model is part of an ambitious R&D project by Meta to create a so-called âuniversal speech translator,â which the company sees as important for growth across its many platforms â from Facebook and Instagram, to developing domains like VR and AR. Machine translation not only allows Meta to better understand its users (and so improve the advertising systems that generate 97 percent of its revenue) but could also be the foundation of a killer app for future projects like its augmented reality glasses.

Osaka University researchers discovered that worms may be coated with hydrogel sheaths that contain useful cargo such as anti-cancer medications
James Bondâs famed quartermaster Q provided the secret agent with an unlimited supply of equipment and gadgets to aid him on his missions. Now, scientists from Japan have shown that they are equally adept in providing microscopic worms with a surprising variety of useful and protective components.
Researchers from Osaka University have discovered that microscopic, free-living worms known as nematodes may be coated with hydrogel-based âsheathsâ that can be further customized to transport functional cargo.
Could a brain ever exist on its own, divorced from or independent of a body? For a long time, philosophers have pondered such âbrain-in-a-vatâ scenarios, asking whether isolated brains could maintain consciousness when separated from their bodies and senses. Typically, a personâs experiences are characterized by a web of interactions between the human brain, body and environment. But recent developments in neuroscience mean this conversation has moved from the realm of hypothetical speculation and science fiction, to isolated examples where consciousness could be sealed off from the rest of the world.
It may sound like science fiction, but can actual science keep a brain alive in a vat?

Context Proposed federal legislation would require physicians to inform women seeking abortions at 20 or more weeks after fertilization that the fetus feels pain and to offer anesthesia administered directly to the fetus. This article examines whether a fetus feels pain and if so, whether safe and effective techniques exist for providing direct fetal anesthesia or analgesia in the context of therapeutic procedures or abortion.
Evidence Acquisition Systematic search of PubMed for English-language articles focusing on human studies related to fetal pain, anesthesia, and analgesia. Included articles studied fetuses of less than 30 weeksâ gestational age or specifically addressed fetal pain perception or nociception. Articles were reviewed for additional references. The search was performed without date limitations and was current as of June 6, 2005.
