David Baum, University of Wisconsin, says: "All agree that eukaryotes arose from a symbiotic relationship between two cell types: bacteria that became mitochondria and a host cell, archaea, or a close relative of archaea, that became the cytoplasm and nucleus. This symbiosis explains the origin of mitochondria, but what about other eukaryotic structures, most notably the nucleus?" The Baums' inside-out theory provides a gradual path by which eukaryotic cells could have evolved. The first stage began with a bacterial cell whose outer membrane forms protrusions, which the Baums call 'blebs', that reached out from the cell. These protrusions trapped free-living mitochondria-like bacteria between them. Using the energy gained from being in close contact with bacteria (and using bacterial-derived lipids), cells were able to get bigger and expand the size of their blebs. The sides of the blebs formed the endoplasmic reticulum and their inner surfaces formed the outer membrane of the nucleus, with the original outer membrane of the archaeon becoming what we now call the inner nuclear membrane. Finally, the fusion of blebs with one another led to the formation of the plasma membrane. The result was the eukaryotic cell as we now know it. This inside-out theory is explained in more detail using a diagram in the research article (see notes to editors).

Squirrels are charismatic creatures that can bring joy and entertainment as they frolic in our backyards and parks. However, when these furry critters start invading our homes or wreaking havoc in our gardens, they can quickly become a nuisance. Squirrel control becomes particularly challenging as their behavior and habits change with the seasons. In this article, we will explore the unique challenges posed by squirrels at each time of year and discuss effective strategies to keep them at bay. Springtime Strategies: As spring arrives, squirrels become more active and enter the breeding season. They may choose to build nests in attics, crawl spaces, or chimneys to give birth and raise their young. To prevent these unwanted guests, it is crucial to inspect your property for any potential entry points and seal them off. Trim tree branches that hang near your roof, as squirrels can use them as bridges to access your home.

Pests can cause significant problems in homes, ranging from property damage to health hazards. Unfortunately, Texas is home to a variety of pests, such as cockroaches, ants, rodents, and termites, that can cause severe damage if not controlled.

The field of artificial intelligence (AI) has experienced remarkable growth and development in recent years, pushing the boundaries of what was once thought possible. In this article, we'll explore the current state of AI evolution and where this fascinating field is heading in the future. We'll delve into various aspects of AI development, including machine learning, natural language processing, robotics, and AI ethics, as well as the role of quantum computing in AI's future.

"Why does all biology happen in academic or industrial labs? Mac Cowell, cofounder of DIYbio, seeks to change that."

"The results are published in Nature Medicine today. Co-author Stanley Hazen, head of cardiovascular medicine at the Cleveland Clinic in Ohio, says that the study could signal a new approach to diet and health. In some cases, an individual's collection of intestinal microbes may be as important to their diet as anything on a nutrition label, he says. "Bacteria make a whole slew of molecules from food," he says, "and those molecules can have a huge effect on our metabolic processes.""

Swiss researchers have reportedly managed to make germanium suitable for lasers, which is important to eventually enable microprocessor components to communicate using light that is 10 times faster than electric currents, essentially becoming much faster photonic computers.

"With 10,000 miles separating them, two makers designed and built a customizable 3-D-printed prosthetic hand for a 5-year old boy named Liam in South Africa for $150 in parts. No power necessary."

"Here we show that four days of immersion in nature, and the corresponding disconnection from multi-media and technology, increases performance on a creativity, problem-solving task by a full 50% in a group of naive hikers. Our results demonstrate that there is a cognitive advantage to be realized if we spend time immersed in a natural setting. We anticipate that this advantage comes from an increase in exposure to natural stimuli that are both emotionally positive and low-arousing and a corresponding decrease in exposure to attention demanding technology, which regularly requires that we attend to sudden events, switch amongst tasks, maintain task goals, and inhibit irrelevant actions or cognitions. A limitation of the current research is the inability to determine if the effects are due to an increased exposure to nature, a decreased exposure to technology, or to other factors associated with spending three days immersed in nature."

"Regardless of the platform, social media interactions require two-way conversations (see Box 2). Joining one of the many preexisting scientific conversations can simultaneously disseminate your own content, expand your online network, and raise your professional visibility.
