Brain Scientists Finally Discover the Glue that Makes Memories Stick for a Lifetime The persistence of memory is crucial to our sense of identity, and without it, there would be no learning, for us or any other animal. It’s little wonder, then, that some researchers have called how the brain stores memories the most fundamental question in neuroscience. A milestone in the effort to answer this question came in the early 1970s, with the discovery of a phenomenon called long-term potentiation, or LTP. Scientists found that electrically stimulating a synapse that connects two neurons causes a long-lasting increase in how well that connection transmits sig…

The WHO has (again) declared the rapid spread of mpox across 13 countries in Africa an emergency over fears of a global spread.

New paper regarding Hubble contention https://arxiv.org/abs/2408.06153 Edit forgot to add a few years back local cluster measurements by HOLICOW were not matching up to CMB measurements. The bulk of the research as to cause from what I've been able to gather have been in regards to local group calibrations similar to the above paper.

Scientists find humans age dramatically in two bursts – at 44, then 60 US findings suggesting ageing is not a slow and steady process could explain spikes in health issues at certain ages If you have noticed a sudden accumulation of wrinkles, aches and pains or a general sensation of having grown older almost overnight, there may be a scientific explanation. Research suggests that rather than being a slow and steady process, aging occurs in at least two accelerated bursts. The study, which tracked thousands of different molecules in people aged 25 to 75, detected two major waves of age-related changes at around ages 44 and again at…

Scientists may have solved one long standing mystery that has puzzled Egyptologists and archaeologists alike for well over a century according to a recent paper: https://elifesciences.org/articles/87513 Egyptian writings and inscriptions dating back to the reign of the pharaoh Sahure in the period of the Old Kingdom c. 2500 BCE testify to a prosperous trade relationship with another kingdom called Punt that supplied the Egyptians with luxury items such as Frankincense, ebony, leopard skins and baboons. The relationship was documented in a Middle Kingdom fictional tale called ‘The Shipwrecked Sailor’ dated to 2000 BCE, and also by an inscription found in a mort…

A novel method of calculating the value of Pi has been found by an Indian physicist Aninda Sinha, Professor at the Centre for High Energy Physics (CHEP) - Indian Institute of Science, and co-author Arnab Saha, a post-doc assistant - published in Physical Review Letters https://www.iisc.ac.in/events/iisc-physicists-find-a-new-way-to-represent-pi/ The new method was stumbled upon by chance while the researchers were investigating how string theory can be used to explain certain physical phenomena: There are several well known methods of calculating Pi by using infinite series, notably the Wallis product formula first published by John Wallis in 1656, and t…

MOND vs. dark matter: Research suggests that rotation curves of galaxies stay flat indefinitely June 17 2024 The primary technique Mistele used in his research, gravitational lensing, is a phenomenon predicted by Einstein’s theory of general relativity. As part of the research, Mistele plotted out what’s called Tully–Fisher relation on a chart to highlight the empirical relationship between the visible mass of a galaxy and its rotation speed. In a discovery that challenges the conventional understanding of cosmology, scientists at Case Western Reserve University have unearthed new evidence that could reshape our perception of the cosmos. Tobias Mistele, a post-doctor…

In the news today major breakthrough of faster than light travel. This changes every thing. Quantum Tunnels Show How Particles Can Break the Speed of Light Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls. https://www.quantamagazine.org/quantum-tunnel-shows-particles-can-break-the-speed-of-light-20201020/ “Quantum tunneling” shows how profoundly particles such as electrons differ from bigger things. Throw a ball at the wall and it bounces backward; let it roll to the bottom of a valley and it stays there. But a particle will occasiona…

As the title says, the WHO has considered bird flu a zoonotic pandemic. https://odishabytes.com/who-sounds-alarm-over-human-cases-of-bird-flu-flags-global-zoonotic-animal-pandemic/ Let us remember that the coronavirus pandemic has not ended, but rather the alert level regarding it was reduced, if I am not mistaken. Now we have a second pandemic, it seems, in about 4 years. Avian flu can affect in many ways, such as affecting food production. But, it has also been mentioned that there is a risk that it could end up being a direct threat to humans.

A marine algae and a nitrogen fixing bacteria have officially teamed up and the bacteria has become a new organelle inside a marine algae. The teaming up of nitrogen fixing bacteria and plants Is not a new (Azolla carolinensis) is one but the bacteria is just in a communal relationship with the plant but this bacteria has actually become an organelle inside the algae cells much like mitochondria or chloroplasts in other cells, this new organelle has been dubbed Nitroplast. https://newscenter.lbl.gov/2024/04/17/scientists-discover-first-nitrogen-fixing-organelle/ I am remembering reading of another animal that has evolved something similar that a…

A group of metazoans known as Loricifera contain at least three species that live their entire lives without oxygen. They depend on mitochondria like organelles called Hydrogenosomes. These organelles allow the organism to produce energy in the absence of oxygen, they live in anoxic sediments. Not considered uniquely evolved from a new organism but actually degenerate mitochondria. . Spinoloricus cinziae was found in 2014.

A mutant virus similar to monkeypox has been detected in the Congo, Africa (called: clade 1b). In fact, it has been classified as a new strain of mpox. Experts believe that it has the potential to become a pandemic. Mpox previously caused a global epidemic, highlighting its virulence capacity. Experts call for quick action to stop the spread of the virus. Let us remember that the majority of deaths from Mpox are children, despite the virus being related to sexual activities.

The omnipresent QR (Quick Response) codes found everywhere these days from restaurant menus, to adverts on bus stops, festival passes, or museum exhibits were first invented back in 1994 at a Japanese company called Denso Wave (デンソーウェーブ), a manufacturer of automobile parts based near Nagoya in Japan. Masahiro Hara, the man who invented QR codes was an engineer at Denso Wave who also happened to be a Go player. One day he was playing a game of Go during his lunchbreak when he stumbled on the idea of using the 19 x 19 matrix of a Go board as a new way of encoding the information of the Kanban (カンバン ) system for tracking components and spare parts which is extensively u…

https://www.cnn.com/2024/04/09/world/peter-higgs-physicist-nobel-winner-dies-scn/index.html Physicist Peter Higgs, whose theory of an undetected particle in the universe changed science and was vindicated by a Nobel prize-winning discovery half a century later, has died aged 94, the University of Edinburgh said on Tuesday. The discovery of the Higgs boson in 2012 at the CERN research centre near Geneva was widely hailed as the biggest advance in knowledge about the cosmos for over 30 years, and pointed physics towards ideas that were once science fiction. “For me personally it is just the confirmation of something I did 48 years ago, and it is very satisfyi…

Scientists say they have successfully eliminated HIV from infected cells, using Nobel Prize-winning Crispr gene-editing technology. Working like scissors, but at the molecular level, it cuts DNA so "bad" bits can be removed or inactivated. The hope is to ultimately be able to rid the body entirely of the virus, although much more work is needed to check it would be safe and effective. https://www.bbc.co.uk/news/health-68609297
