Although early detection of many types of cancer has contributed to the recent increases in cancer survival rates, the survival rate for has remained almost unchanged for over 20 years. Partly this is due to their late detection. Physicians often discover only after the onset of neurological symptoms, such as loss of movement or speech, by which time the tumor has reached a considerable size. Detecting the tumor when it is still small, and starting treatment as soon as possible, should help to save lives.

One possible sign that a person has a brain tumor is the presence of tumor-related extracellular vesicles (EVs) in their urine. EVs are nano-sized vesicles involved in a variety of functions, including cell-to-cell communication. Because those found in patients have specific types of RNA and membrane proteins, they could be used to detect the presence of cancer and its progression.

Elon Musk said Twitter will launch an early version of its program allowing creators to get paid for tweets as soon as next week

Posted by in category: Elon Musk

Elon Musk said Twitter will introduce an early version of a long-teased new feature on the platform allowing creators to be paid for their tweets as soon as next week.

Musk responded to a tweet on Tuesday by a user who said Twitterโ€™s co-tweet feature which lets users co-author tweets together is โ€œstupid afโ€ to which Musk responded: โ€œYouโ€™re welcome. Axed them yesterday to focus on enabling writers to add essays as attachments to tweets.

Combined with improvements to creator subscriptions (fka superfollow), you will be able to publish directly on Twitter & get paid for it.

It was a life-changing day for 12 patients living in the United States when they found that their cancer had vanished, thanks to a small clinical trial. Of the total number of patients, these were the patients who completed the trial.

The New York Times reported that a drug named Dostarlimab was administered to these patients โ€” all suffering from rectal cancer โ€” over six months. All 12 patients entered remission after the period.

Ready for Googleโ€™s Version of ChatGPT? We May Get a Glimpse Next Week

Posted by in categories: mapping, robotics/AI

Googleโ€™s competitor to OpenAIโ€™s ChatGPT may appear as soon as next week. The company will hold an event in Paris on Wednesday, Feb. 8, where it will discuss plans for its search engine.

The company isnโ€™t revealing much about the event. The description merely says (Opens in a new window) : โ€œWeโ€™re reimagining how people search for, explore and interact with information, making it more natural and intuitive than ever before to find what you need. Join us to learn how weโ€™re opening up greater access to information for people everywhere, through Search, Maps, and beyond.โ€

A cnidarian parasite of salmon (Myxozoa: Henneguya) lacks a mitochondrial genome

Posted by in categories: bioengineering, biotech/medical

Year 2020 This type of parasite that feeds on salmon actually doesnโ€™t need oxygen to live. Which means eventually there could be even gene editing that could essentially allow humans to not need as much air or could be independent of oxygen but only need anaerobic metabolisms perhaps. Really this can only expand our understanding of new ways to evolve humans to the next level.


Although aerobic respiration is a hallmark of eukaryotes, a few unicellular lineages, growing in hypoxic environments, have secondarily lost this ability. In the absence of oxygen, the mitochondria of these organisms have lost all or parts of their genomes and evolved into mitochondria-related organelles (MROs). There has been debate regarding the presence of MROs in animals. Using deep sequencing approaches, we discovered that a member of the Cnidaria, the myxozoan Henneguya salminicola, has no mitochondrial genome, and thus has lost the ability to perform aerobic cellular respiration. This indicates that these core eukaryotic features are not ubiquitous among animals. Our analyses suggest that H. salminicola lost not only its mitochondrial genome but also nearly all nuclear genes involved in transcription and replication of the mitochondrial genome. In contrast, we identified many genes that encode proteins involved in other mitochondrial pathways and determined that genes involved in aerobic respiration or mitochondrial DNA replication were either absent or present only as pseudogenes. As a control, we used the same sequencing and annotation methods to show that a closely related myxozoan, Myxobolus squamalis, has a mitochondrial genome. The molecular results are supported by fluorescence micrographs, which show the presence of mitochondrial DNA in M. squamalis, but not in H. salminicola. Our discovery confirms that adaptation to an anaerobic environment is not unique to single-celled eukaryotes, but has also evolved in a multicellular, parasitic animal. Hence, H. salminicola provides an opportunity for understanding the evolutionary transition from an aerobic to an exclusive anaerobic metabolism.

Unsolved for 500 Years: Researchers Crack Leonardo da Vinciโ€™s Paradox

Posted by in category: particle physics

Professors Miguel รngel Herrada of the University of Seville and Jens G. Eggers of the University of Bristol have uncovered a mechanism that explains the erratic movement of bubbles rising in water. The findings, published in the prestigious journal Proceedings of the National Academy of Sciences, could provide insights into the behavior of particles that fall between solid and gas states.

Leonardo da Vinci observed five centuries ago that air bubbles, if big enough, periodically deviate in a zigzag or spiral from a straight-line movement. However, no quantitative description of the phenomenon or physical mechanism to explain this periodic motion had ever been found.
