Ion channels are crucial for neural communication; they control the flow and gradient of charged particles, creating electrical signals. Recent work report | Neuroscience.


In this study, the researchers assessed how dense ion channels were packed in the membranes of neuronal cells from ten species of mammals, including mice, rats, rabbits, ferrets, macaques, marmosets, macaques, humans, and one of the smallest known mammals, an animal called the Etruscan shrew. The team focused on a type of excitatory neuron typically found in the cortex of the brain, and three ion channels that are in the membranes of those cells; two are voltage-gated ion channels that control the movement of potassium, another is called the HCN channel and both potassium and sodium ions can flow through it.

Studies have suggested that the human brain is built like the brains of other mammals, said first study author Lou Beaulieu-Laroche, a former MIT graduate student. It was once thought that in mammals, these channels would be present at about the same density from one species to another.

Instead, the researchers determined that as the neurons got bigger, the density of ion channels increased. That was a notable finding, because as that density increases, more energy needed to move ions in and out of neurons, explained senior study author Mark Harnett, an associate professor of brain and cognitive sciences at MIT.

He’s absolutely right about birth rates and its implications for our species. OVER population is a disproven concept as far as our near and near-far future goes.

University associations are looking to make research papers and publications open to all by dropping paywalls.


The European University Association (EUA) consists of 850 academic institutions covering 48 countries. Created in 2001 they are responsible for the education and training of more than 17 million students across Europe. In creating the Association, European academics have endeavoured to create a common educational standard and policies related to educational and research accountability and processes. They are not alone in doing this, joined by like-minded organizations such as OA2020, the Max Planck Society open access initiative, and the IFLA, the International Federation of Library Associations and Institutions.

Since the COVID-19 pandemic outbreak, the need to accelerate research and development of new vaccines and medications has fostered a move for greater openness in publishing and sharing research. This has spirited a recently unveiled strategy, the EUA Open Science Agenda 2025 promoting open access to research and scholarly publications, and the removal of paywalls from scientific and academic journals and publications of European origin.

An open science agenda will involve the creation of new systems for evaluating independent research and will make it easier for the scientific and academic community to learn from each other while disseminating information to the general public that will continue to be peer-reviewed.

“The proportions of different isotopes of elements present in the bedrock and water create a unique profile, specific to each place on Earth. This profile remains consistent over the millennia and is a kind of “fingerprint” of a region, which can be found in plants, rocks and even animal remains.” National Geographic Poland.

“One of the mammoth’s tusks became a perfect record of all the places the animal visited in its lifetime — with an accuracy almost to the day.”


An international research team has retraced the astonishing lifetime journey of an Arctic woolly mammoth, which covered enough of the Alaska landscape during its 28 years to almost circle the Earth twice.

Scientists gathered unprecedented details of its life through analysis of a 17,000-year-old fossil from the University of Alaska Museum of the North. By generating and studying isotopic data in the mammoth’s tusk, they were able to match its movements and diet with isotopic maps of the region.

Few details have been known about the lives and movements of woolly mammoths, and the study offers the first evidence that they traveled vast distances. An outline of the mammoth’s life is detailed in the new issue of the journal Science.

Fraunhofer ISE has developed a process for recycling the silicon in old solar panels.


The big knock on new technology like electric cars and solar panels is that they are not recyclable. People haven’t cared a flying fig leaf about recycling stuff for the past 100 years. If they did, citizens would be at the gates of the corporate headquarters of Nestlé, Coca Cola, and Pepsi with flaming torches and pitchforks demanding they stop inundating the Earth with their endless profusion of waste products.

But suddenly, people are all atwitter about what will happen to the batteries of electric cars. Fearmongers on the internet are telling people they will have to drive their old electric cars into lakes and rivers when they stop working. The amazing thing is, people believe that codswallop and repeat it to their friends as if it were carved on the stone tablets Moses brought down with him when he descended the mountain. So much for public education making people smarter.

Another cry you hear from the anti-technology crowd is that millions of old solar panels will be dumped into landfills to fester for centuries. Horse-puckey! Do we need a way to recycle solar panels? Yes, we do. And are responsible adults working on such systems as we speak? Yes, they are. Calm down, people. Everything you read on Twitter or Facebook is not gospel. And let’s not get started on the deliberate misinformation spewed by the talking heads on Faux News 24 hours a day.

“Beneficial Viruses” For Human Health, Agriculture And Environmental Sustainability — Dr. Marilyn Roossinck, Ph.D., Professor Emeritus, Penn State


Dr. Marilyn Roossinck Ph.D. (https://plantpath.psu.edu/directory/mjr25) is Professor Emeritus of plant pathology, environmental microbiology and biology at Penn State University.

Dr. Roossinck is an expert on viruses, from their evolutionary pressures and mechanisms, to the ecology of viral diseases. She performed some of the first experimental evolution studies on plant viruses and pioneered the first virus discovery work in a terrestrial system, by deep sequencing wild plant samples. A specialty of hers is the symbiotic relationships between plants and so-called “beneficial viruses.”

Dr. Roossinck completed her undergraduate work at the University of Colorado, Boulder, receiving a biology degree in 1982. Four years later, she earned her doctorate in microbiology and immunology from the University of Colorado School of Medicine.

Dr. Roossinck joined Penn State as professor of plant pathology and environmental microbiology and of biology in 2011, holding appointments in the College of Agricultural Sciences and the Eberly College of Science. She taught courses in virus ecology for several years at Penn State, and also has published both a popular press book about viruses entitled “Virus: An Illustrated Guide to 101 Incredible Microbes” as well as the academic text “Plant Virus Evolution”.

When I was ten years old, I discovered computers. My first machine was a PDP-10 mainframe system at the medical center where my father worked. I taught myself to write simple programs in the BASIC computer language. Like any ten-year-old, I was especially pleased to discover games on the computer. One game was simply labeled “ADVENT.” I opened it and saw:

You are standing at the end of a road before a small brick building. Around you is a forest. A small stream flows out of the building and down a gully.

I figured out that I could move around with commands like “go north” and “go south.” I entered the building and got food, water, keys, a lamp. I wandered outside and descended through a grate into a system of underground caves. Soon I was battling snakes, gathering treasures, and throwing axes at pesky attackers. The game used text only, no graphics, but it was easy to imagine the cave system stretching out below ground. I played for months, roaming farther and deeper, gradually mapping out the world.

Chinese mobility manufacturer BYD has introduced its new “Type A” electric school bus to transport up to thirty US students at a time. Furthermore, the new zero-emission bus is ADA capable up to 800 lbs and can travel 140 miles on a single charge. What may be most appealing to school districts, however, is the vehicle-to-grid (V2G) capabilities BYD’s Type A school bus will provide.

BYD is an acronym for “Build Your Dreams,” a motto the Chinese automaker has followed since 1995 when it was founded. BYD Auto, the subsidiary of BYD Co. Ltd. will be celebrating its 20th anniversary next year, as it sits as one of the largest auto manufacturers in China. In 2021, BYD produced over 320,000 BEVs, second in the country only to SAIC.

In addition to manufacturing unique “blade” EV batteries, BYD Auto develops and manufactures electric cars, buses, trucks, bicycles, and even forklifts – under its own monicker as well as for other OEMs like Toyota.
