New Class of Antibiotics Proves Potent Against Multi-Drug Resistant Bacteria

This study describes the identification of an antibiotic class acting via LpxH, involved in lipopolysaccharide synthesis having potent in vivo efficacy against bloodstream infections caused by the critical Gram-negative pathogens E. coli and Klebsiella pneumoniae. Further development of this class of antibiotics could make an important contribution to the ongoing struggle against antibiotic resistance.

Reducing Alzheimer’s Risk by 70%

This study attempts to identify the “protective” genetic factors that can modify or reduce the effect of APOEε4 on Alzheimer’s disease risk and to identify new pathogenic mechanisms, proteins, and pathways that inform development of therapeutic targets and diagnostics.

  • I'm very new to using rss. Recently I have come across people mentioning about adding rss feeds of youtube channels to rss readers. I'm curious to know how to get the URL of youtube channel rss so I could add it to my reader (I hope I am wording it correctly). I am using feeder app.

  • I have frequently used tts for listening to epubs. I have, however, not noticed much battery drain... And it's not as enjoyable as listening to an audiobook read by a narrator you like but it kind of works to a certain extent. So I wish you tts would get better.

    Live birth of chimeric monkey with high contribution from embryonic stem cells

    Scientists have created an infant ‘chimeric’ monkey by injecting a monkey embryo with stem cells from a genetically distinct donor embryo. The resulting animal is the first live-born chimeric primate to have a high proportion of cells originating from donor stem cells. However, the monkey had to be euthanized when it was only ten days old, due to health issues, thereby raising ethical concerns. DOI: 10.1016/j.cell.2023.10.005

  • One of the things I really like about Mastodon is that I can curate my feed to show only what I am interested in by following hashtags and/or people and muting those people whose posts I don't want to see. There's no hidden algorithm controlling my feed, pushing controversial posts towards me and other stuff. So I don't get why would you need the invite only feature of bluesky control your feed?

    Taking a look at how the use of solar energy has evolved, from ancient civilizations leveraging passive sunlight to modern photovoltaic milestones.

  • I guess different people have different use cases. I am enjoying Mastodon and have had positive interactions with people. I have also found a lot of good quality content there. Additionally, I totally avoid political stuff so haven't had any issues of political stuff messing up my feed. IMO the invite only thing is just increasing attractiveness by creating artificial scarcity.

    Astronomers have been closely monitoring Bennu, which swings close to Earth every six years. However, the real cause for concern arises from the possibility that on September 24, 2182, Bennu could collide with our planet with a force equivalent to 22 atomic bombs. While the odds of such a catastrophic strike are estimated at 1 in 2,700, NASA is not taking any chances.

    Feline thief Gingee, a four-year-old Maine Coon, has been ransacking nearby homes in Buckley, Flintshire.

    The most startling moment for owners Jay Phoenix, 43 and Mathew Westlake-Toms, 31, was when Gingee delivered a stolen knife to their bedroom at night.

    The concrete dome of the Pantheon in Rome remains stable enough for visitors to walk beneath, and some Roman harbours have underwater concrete elements that have not been repaired for two millennia – even though they are in regions often shaken by earthquakes.

    Whence this remarkable resilience of Roman concrete architecture? It’s all down to the chemistry.

    A key function of our immune system is to detect and eliminate foreign pathogens such as bacteria and viruses. Immune cells like T cells do this by distinguishing between different types of proteins within cells, which allows them to detect the presence of infection or disease.

    A type of T cell called cytotoxic T cells can recognize the mutated proteins on cancer cells and should therefore be able to kill them. However, in most patients, cancer cells grow unchecked despite the presence of T cells.

    The current explanation scientists have as to why T cells fail to eliminate cancer cells is because they become “exhausted.” The idea is that T cells initially function well when they first face off against cancer cells, but gradually lose their ability to kill the cancer cells after repeated encounters.

    Cancer immunotherapies such as immune checkpoint inhibitors and CAR-T cell therapy have shown remarkable promise by inducing long-lasting remission in some patients with otherwise incurabl

    Scientists Discover Natural Molecule That Eradicates Plaques and Cavities

    Scientists have discovered that the molecule DIM reduces biofilms causing dental plaque by 90%. Its addition to toothpaste and mouthwash could revolutionize dental hygiene. 3,3′-Diindolylmethane (DIM) decreased the Streptococcus mutans biofilm, a leading contributor to plaque and cavities, by 90%.

    A significant portion of the global population experiences persistent issues with dental plaque and cavities or will face them at some time. While toothpaste, mouthwash, and routine dental visits help in prevention, there’s always room for improvement.

    Researchers from Ben-Gurion University of the Negev, in collaboration with teams from Sichuan University and the National University of Singapore, have identified that 3,3′-Diindolylmethane (DIM) – a naturally occurring molecule also referred to as bisindole – can reduce biofilms responsible for plaque and cavities by a remarkable 90%.
