Scientists Find The Highest-Ever Concentration of Microplastics on The Seafloor
Scientists Find The Highest-Ever Concentration of Microplastics on The Seafloor
We found up to 1.9 million pieces of microplastic in a 5 cm-thick layer covering just one square metre – the highest levels of microplastics yet recorded on the ocean floor.

Obviously, I haven't clicked on this thread in a while. But this article reminded me of Grund's excellent discussion on usage of 3D space: Diegesis. Of course, David is one of the examples.Daehawk wrote: ↑Thu Dec 26, 2019 5:40 pm https://techcrunch.com/2019/12/24/micro ... eter-tall/
Micro-angelo? This 3D-printed ‘David’ is just one millimeter tall.
It was created using Exaddon’s “CERES” 3D printer, which lays down a stream of ionized liquid copper at a rate of as little as femtoliters per second, forming a rigid structure with features as small as a micrometer across. The Tiny David took about 12 hours to print, though something a little simpler in structure could probably be done much quicker.

This weird-looking fish is a hybrid offspring of the American paddlefish and Russian sturgeon, both critically endangered.
Using gynogenesis (a method of asexual reproduction that requires the presence of sperm without the contribution of their DNA for completion), the researchers accidentally used paddlefish sperm to fertilize the sturgeon eggs. Remarkably, the hybridization worked.

Just how tough is life? Scientists revived 100 million year old microbes.
Japanese scientists say they have revived microbes that were in a dormant state for more than 100 million years.
The tiny organisms had survived in the South Pacific seabed - in sediment that is poor in nutrients, but has enough oxygen to allow them to live.
Microbes are among the earth's simplest organisms, and some can live in extreme environments where more developed life forms cannot survive.
After incubation by the scientists, the microbes began to eat and multiply.

Re: SCIENCE and things like that
NPR
The first genetically-altered squid has scientists excited about a potential new way to study marine critters that are so weird, they've sometimes been compared to alien life forms.
Scientists report this week that they have disabled a pigmentation gene in a squid called Doryteuthis pealeii. Their success shows that cephalopods—which include squid and octopuses--can finally be studied using the same kind of genetic tools that have let scientists explore the biology of more familiar lab animals like mice and fruit flies. Those are easy to keep in the laboratory, and scientists routinely modify their genes to get insights into behavior, diseases, and possible treatments.
It's almost as if people are the problem.

Re: SCIENCE and things like that
Independent
Scientists in the Netherlands say they have identified a potential new organ in the human throat.
Researchers say the newly-found set of salivary glands are likely being used for moistening and lubricating the upper parts of the throat, and that they stumbled upon them while carrying out research on prostate cancer.
...
The research said that the throat in humans contains “previously overlooked bilateral macroscopic salivary glands” which the scientists named as “tubarial glands”. The researchers examined at least 100 patients to confirm their findings and found that all of them had the glands.
...
Doctors using radiotherapy for treatment of cancers in the head and neck try to avoid the main salivary glands, as damaging them could make eating, speaking or swallowing difficult for patients. But these newly discovered glands were still getting hit by radiation, as doctors were not aware of their existence, resulting in patients feeling unexplained side effects.

Physicists circumvent centuries-old theory to cancel magnetic fields
A team of scientists including two physicists at the University of Sussex has found a way to circumvent a 178-year old theory which means they can effectively cancel magnetic fields at a distance. They are the first to be able to do so in a way which has practical benefits.
The work is hoped to have a wide variety of applications. For example, patients with neurological disorders such as Alzheimer's or Parkinson's might in future receive a more accurate diagnosis. With the ability to cancel out 'noisy' external magnetic fields, doctors using magnetic field scanners will be able to see more accurately what is happening in the brain.

New research links serotonin and dopamine not just to addiction and depression, but to the ability to control genes.
New research links serotonin and dopamine not just to addiction and depression, but to the ability to control genes.
“Half of what you learned in college is wrong,” my biology professor, David Lange, once said. “Problem is, we don’t know which half.” How right he was. I was taught to scoff at Jean-Baptiste Lamarck and his theory that traits acquired through life experience could be passed on to the next generation. The silly traditional example is the mama giraffe stretching her neck to reach food high in trees, resulting in baby giraffes with extra-long necks. Then biologists discovered we really can inherit traits our parents acquired in life, without any change to the DNA sequence of our genes. It’s all thanks to a process called epigenetics — a form of gene expression that can be inherited but isn’t actually part of the genetic code. This is where it turns out that brain chemicals like dopamine play a role.

Re: SCIENCE and things like that
The inheritance of epigenetic changes to the genome has been known for awhile. Unlike actual evolution (i.e. changes to the genetic code), epigenetic effects disappear after a couple of generations. Still, it can lead to some cool stuff like children of parents that went through periods of starvation being skinnier/living longer even if they don’t go through periods of starvation themselves.
