Octopus' blue blood allows them to rule the waves

Octopus' blue blood allows them to rule the waves | Biosciencia News | Scoop.it
Worldwide colonization by octopods is in their blood! They manage to survive temperature habitats ranging from as low as -1.8°C to more than 30°C due to their ability to keep supplying oxygen to their body tissues.
Biosciencia's insight:

The researchers found that the forms of haemocyanin of the Antarctic octopod Pareledone charcoti, are genetically and functionally different from the temperate and warmer climate octopods, facilitating oxygen release at sub-zero temperatures.

Arithmetic division guides plants' use of energy at night.
Biosciencia's insight:

As if making food from light were not impressive enough, it may be time to add another advanced skill to the botanical repertoire: the ability to perform — at least at the molecular level — arithmetic division.

Reading DNA, backward and forward

Reading DNA, backward and forward | Biosciencia News | Scoop.it
MIT biologists have discovered a mechanism that allows cells to read their own DNA in the correct direction and prevents them from copying most of the so-called “junk DNA” that makes up long stretches of our genome.
Biosciencia's insight:

DNA, which is housed within the nucleus of cells, controls cellular activity by coding for the production of RNAs and proteins. To exert this control, the genetic information encoded by DNA must first be copied, or transcribed, into messenger RNA (mRNA).

Blocking boozy memories reduces risk of relapse

Blocking boozy memories reduces risk of relapse | Biosciencia News | Scoop.it
Molecule associated with learning and memory could be key to treating alcoholism.
Biosciencia's insight:

Wiping out drinking-associated memories could help those with alcohol problems to stay sober, suggests a study in rats.

As with other forms of addiction, environmental cues linked to drinking — such as the smell of beer — can trigger the urge to consume alcohol and increase the risk of a relapse into abuse. Over time, these learned associations can be maddeningly difficult to break.

Lists of cancer mutations awash with false positives

Lists of cancer mutations awash with false positives | Biosciencia News | Scoop.it
But researchers show artefacts can be reduced by taking differing rates of mutation into account.
Biosciencia's insight:

Tumour cells, such as these from a lung cancer, are riddled with genetic mutations, but many of those are caused by the cancer rather than being involved in causing the disease.

Molecules that signal cell death quash nascent rooster genitals.
Biosciencia's insight:

The case of the missing bird penis is a long-standing mystery in evolutionary biology. But the identification of a molecular mechanism that controls penis loss in birds goes some way to solving this conundrum.

Adult stem cells will be used to develop synthetic blood, which will be designed to assist blood banks and minimize infusion-related infections.
Biosciencia's insight:

After decades mired in controversy, legal battles, and ethical dilemmas the United Kingdom's Medical and Healthcare products Regulatory Agency (MHRA) granted a license that will allow researchers at the Scottish National Blood Transfusion Service, Edinburgh University, and Roslin Cells to set up a facility for the testing of synthetic blood in human trials.

Bacterium Planococcus halocryophilus Offers Clues about Microbial Life on Enceladus, Mars | Biology, Space Exploration | Sci-News.com | Biosciencia News | Scoop.it
Bacterium Planococcus halocryophilus that is able to thrive at minus 15 degrees Celsius offers clues about microbial life on both Mars and Enceladus.
Biosciencia's insight:

A novel aerobic, gram-positive bacterium that is able to thrive at minus 15 degrees Celsius  - the coldest temperature ever reported for bacterial growth – offers clues about microbial life on both Mars and the Saturn moon Enceladus, where similar briny subzero conditions are thought to exist, says a McGill University-led team of researchers.

First Quantum-Enhanced Images of a Living Cell | MIT Technology ... | Biosciencia News | Scoop.it
Biologists have used “squeezed light” to create the first images of a living cell that beat the diffraction limit.
Biosciencia's insight:

Today, Michael Taylor at the University of Queensland in Australia and a few pals reveal a new way to create optical images of cells that dramatically increases their resolution beyond the conventional diffraction limit. Their trick relies on a peculiar quantum phenomenon called “squeezed light” which has allowed them to resolve spatial  structures inside a living cells at a resolution of 10 nanometres; that’s a 14 per cent finer resolution than is possible with conventional techniques.

Researchers have engineered a new adeno-associated virus that could greatly expand gene therapy to help restore sight to patients with blinding diseases.
Biosciencia's insight:

Over the last six years, several teams of scientists have successfully treated people with a rare inherited eye disease by injecting a virus with a normal gene directly into the retina of an eye with a defective gene.

Nanoparticles that deliver short strands of RNA offer a way to treat cancer and other diseases by shutting off malfunctioning genes.
Biosciencia's insight:

Helping RNA escape from cells’ recycling process could make it easier to shut off disease-causing genes. Nanoparticles that deliver short strands of RNA offer a way to treat cancer and other diseases by shutting off malfunctioning genes. Although this approach has shown some promise, scientists are still not sure exactly what happens to the nanoparticles once they get inside their target cells.

New Microscope Optics Completely Destroy Diffraction Barrier--Revealing a Whole New Understanding of | Biosciencia News | Scoop.it

Indeed such inventions are so new that many scientists are certain there are many new discoveries to come. Who knows what sort of views these new techniques may yield with a few more tweaks, and inventions.

As mentioned before most science about cells is simply hypothesised about how they operate. Now we can look inside and see how exactly they are working with their co-habitants. Science is amazing.

Biosciencia's insight:

Microscopes were first invented in 1590 by two eyeglass makers later to have the term, “Microscope” coined by  Giovanni Faber coined the name microscope for Galileo Galilei‘s compound microscope in 1625. We now commonly use the modern light microscope that we’ve all probably played with at some point in our early schooling.

Wonderful Things: Desmids, Microscopic Plants of Unusual Beauty and Oddball Behavior

Wonderful Things: Desmids, Microscopic Plants of Unusual Beauty and Oddball Behavior | Biosciencia News | Scoop.it
Sometimes I want to show you something just because it's wonderful. So today I'm introducing a new feature: Wonderful Things. The name is taken from my blog's masthead, but is also inspired by Howard Carter .
Biosciencia's insight:

Sometimes I want to show you something just because it’s wonderful. So today I’m introducing a new feature: Wonderful Things. The name is taken from my blog’s masthead, but is also inspired by Howard Carter. When he broke in to the tomb of Tutankhamun, he stuck a candle in the hole and surveyed the contents. After a pause, his patron Lord Carnarvon asked him if he saw anything. “Yes,” Carter replied. “Wonderful things.”

So here’s Wonderful Thing #1: Desmids. I stumbled on these as I was writing about the Alternation of Generations in my post a few back on mosses. With tiny, sculpted bodies and some distinctly unplantlike behavior, desmids are gorgeous botanical oddballs. The best description for them might be “chiseled” — although not the sort of chiseling that comes from protein shakes and 6-minute abs. This is more the kind that comes from guys with Italian last names and lucrative papal commissions.
