Posted by in categories: drones, robotics/AI

Feline-inspired vision technology enhances accuracy in challenging environments, paving the way for smarter, more efficient autonomous systems.

Researchers have unveiled a vision system inspired by feline eyes to enhance object detection in various lighting conditions. Featuring a unique shape and reflective surface, the system reduces glare in bright environments and boosts sensitivity in low-light scenarios. By filtering unnecessary details, this technology significantly improves the performance of single-lens cameras, representing a notable advancement in robotic vision capabilities.

Autonomous systems like drones, self-driving cars, and robots are becoming more common in our daily lives. However, they often struggle to “see” well in different environments — like bright sunlight, low light, or when objects blend into complex backgrounds. Interestingly, nature may already have the solution to this problem.

Anastasis: cell recovery mechanisms and potential role in cancer

Posted by in category: biotech/medical

Balanced cell death and survival are among the most important cell development and homeostasis pathways that can play a critical role in the onset or progress of malignancy steps. Anastasis is a natural cell recovery pathway that rescues cells after removing the apoptosis-inducing agent or brink of death. The cells recuperate and recover to an active and stable state. So far, minimal knowledge is available about the molecular mechanisms of anastasis. Still, several involved pathways have been explained: recovery through mitochondrial outer membrane permeabilization, caspase cascade arrest, repairing DNA damage, apoptotic bodies formation, and phosphatidylserine. Anastasis can facilitate the survival of damaged or tumor cells, promote malignancy, and increase drug resistance and metastasis.

Anastasis induced by bee venom in normal cells compared to persistent cell death in breast cancer cells

Posted by in category: biotech/medical

Anastasis is a phenomenon that has been recently defined as a return from induced apoptosis. Its mechanism has not been clearly elucidated. Anastasis is thought to be involved in the development of drug resistance in cancer cells, however the distinct regulation of anastasis in normal and cancerous cells during anti-cancer therapy has not been discovered. One of the most privileged therapy strategies focuses on the drugs that are selectively cytotoxic in cancer cells but not negatively affect normal cell proliferation. This study for the first time comparatively evaluated the anastatic effect of a common synthetic cytotoxic agent, cisplatin and a natural cytotoxic agent, bee venom. The study showed that bee venom induced anastasis in normal cells (MCF10A, NIH3T3 and ARPE19) but cancer cells (MDA-MB-231 and MCF7) were irreversibly in cell death process.

Frontiers: Honeybees have been helpful insects since ancient centuries, and this benefit is not limited to being a honey producer only

Posted by in categories: biotech/medical, chemistry, food, nanotechnology

After the bee stings a person, pain, and swelling occur in this place, due to the effects of bee venom (BV). This is not a poison in the total sense of the word because it has many benefits, and this is due to its composition being rich in proteins, peptides, enzymes, and other types of molecules in low concentrations that show promise in the treatment of numerous diseases and conditions. BV has also demonstrated positive effects against various cancers, antimicrobial activity, and wound healing versus the human immunodeficiency virus (HIV). Even though topical BV therapy is used to varying degrees among countries, localized swelling or itching are common side effects that may occur in some patients. This review provides an in-depth analysis of the complex chemical composition of BV, highlighting the diverse range of bioactive compounds and their therapeutic applications, which extend beyond the well-known anti-inflammatory and pain-relieving effects, showcasing the versatility of BV in modern medicine. A specific search strategy was followed across various databases; Web of sciences, Scopus, Medline, and Google Scholar including in vitro and in vivo clinical studies.to outline an overview of BV composition, methods to use, preparation requirements, and Individual consumption contraindications. Furthermore, this review addresses safety concerns and emerging approaches, such as the use of nanoparticles, to mitigate adverse effects, demonstrating a balanced and holistic perspective. Importantly, the review also incorporates historical context and traditional uses, as well as a unique focus on veterinary applications, setting it apart from previous works and providing a valuable resource for researchers and practitioners in the field.

Bees are commercially beneficial insects that have been around since the Cretaceous age of the Mesozoic Era. They also help fertilize many different crops. Bees are helpful, but their capacity to administer excruciating and poisonous stings constitutes a risk. Thankfully, most honeybees are not hostile to people and only resort to violence if they perceive danger (Pucca et al., 2019). Apis mellifera is the most often used honeybee species for agricultural pollination globally. All bee products, particularly venom, and honey, have been used for centuries, and their medicinal properties have been described in holy writings such as the Bible and the Quran (Ali, 2024; Dinu et al., 2024). Bee venom (BV) treatment involves injecting honeybee venom into the human body to cure various ailments. For over 5,000 years, this technique has been used in complementary therapies.

The Kardashev Scale: Type 1 To Type 7 Civilizations And Reverse Scale

Posted by in categories: alien life, Elon Musk, supercomputing

Discovering Advanced Civilizations: Type 1 To 7 And Minus 0 To Minus 3: How Far Can We Go?
he kardashev scale type From Type 1 To 7 And Theand Reverse Scale: How Far Can We Go?
The Kardashev scale is a method used to determine a civilization’s technological advancement, which divides civilizations into three types, with type 1 being the simplest civilization of all.
The civilization created by the human race is not yet advanced enough to be considered a type 1 civilization. How long until we reach that classification? Stay to find out.
“Introduction“
Astrophysicist Nikolai Kardashev developed the Kardashev scale in 1964 to determine some characteristics that would facilitate the search for extraterrestrial life.
After analyzing several conditions in the history of the human race, Kardashev realized that there is a need that grows as civilization does, energy.
As the human race has expanded worldwide, so needs for energy.
Suppose this is inherent in all species that become an intelligent race. In that case, a hypothetical race of aliens who come to forge a civilization as significant or more extensive than that of humans will eventually also have an energy deficit.
To solve this energy need, an extraterrestrial race must develop technologies to meet the demand for energy needed to sustain all members of their civilization.
Kardashev theorized that in this sense, there must be 3 types of civilizations:
Type 1: A civilization that can harness all the energy its home planet gives them.
Type 2: A civilization that can harness the energy of its entire solar system.
Type 3: A civilization that can harness all the energy provided by the galaxy it is in.

“A type VII or K7 civilization would travel, transcend and ultimately oversee or ”be” the Omniverse which is the collection of every single universe, multiverse, megaverse, paraverse, 11d dimension, and 1st realm (reality). Everything is in the Omniverse, and there is only one Omniverse.” In other words, such a civilization would be as closest as godly as possible.
However, the achievement of a type 7 civilization will only be the end of a very long process of technological advancement and connection with the cosmos. To get there, we would first need to go to all the other civilization types that make up the scale. Let’s see what they consist of.

“Astonishing” — Scientists Unveil First Blueprint of the Most Complex Molecular Machine in Human Biology

Posted by in categories: biotech/medical, genetics, nanotechnology, neuroscience

Scientists at the Centre for Genomic Regulation (CRG) in Barcelona have developed the first comprehensive blueprint of the human spliceosome, the most complex and intricate molecular machine found in every cell. This groundbreaking achievement, over a decade in the making, was published in the journal Science.

The spliceosome edits genetic messages transcribed from DNA, allowing cells to create different versions of a protein from a single gene. The vast majority of human genes – more than nine in ten – are edited by the spliceosome. Errors in the process are linked to a wide spectrum of diseases including most types of cancer, neurodegenerative conditions, and genetic disorders.

The sheer number of components involved and the intricacy of its function has meant the spliceosome has remained elusive and uncharted territory in human biology – until now.
