SAN FRANCISCO, Sept. 1 (Xinhua) -- Researchers at two U.S. universities have found that bacteria can act as an aphrodisiac for one-celled ...

LONDON (Reuters) - Scientists have taken a big step toward designing complex forms of life from scratch by constructing five new artificial chromosomes of baker's yeast, representing a third of the micro-organism's genome, or genetic blueprint.
So why all the fuss over a few million artificial base pairs of a simple, single-celled fungus? The humble baker's yeast plays a crucial role in synthetic biology.
"To me, this was an astonishing fact: These histories of these two enzymes across the eukaryote tree, and also including some bacteria, look pretty close to identical.
This stylistic diagram shows a gene in relation to the double helix structure of DNA and to a chromosome (right). The chromosome is X-shaped because it is dividing.
Notably, they flag the possibility of a new interference based on a separate UCB patent application with specific eukaryote claims and emphasise that the PTAB did not decide who was "first to invent" the use of CRISPR/Cas9 in eukaryotes. The statement ...
It could be as simple as the jump from a prokaryote to eukaryote cell or it could be something so complicated our pre-filter brains can't even comprehend it.
At some point after that, around 3.5 to 3.8 billion years ago, the Last Universal Common Ancestor lived, and its descendants split off into precursors for the three domains of life we see today: archaea, bacteria, and eukarya - which we belong to. But ...
This stylistic diagram shows a gene in relation to the double helix structure of DNA and to a chromosome (right). The chromosome is X-shaped because it is dividing.

But that's the essence of the symbiosis hypothesis - the bacteria gets together with an archaea and it makes a eukaryote, the bacteria becomes the mitochondria and the archaea becomes the nucleus cytoplasmic host. That's the theory. It's very, very ...
I recently had a three-way phone conversation with Swedish deep evolution investigators Charles Kurland and Ajith Harish about their phylogenomic Tree of Life (ToL) based on protein structure, which shows that we are descended from a "complex" ancestor ...
This is in contrast to the common models of eukaryote cell movement where either a leading edge of the cell reaches forward, anchors, and the rear end follows (termed cell crawling) or motility is flagellar driven.
The microorganism that causes the disease is a type of parasitic protozoan, that is a unicellular eukaryote. The main target for the disease is the liver.
... is now released from the interference and may be prosecuted to potential issuance by UC, while a new interference can be sought with respect to eukaryote claims, currently pending in a separate UC patent application once they are deemed allowable.

The first one states that mitochondria were prokaryotic cells that efficiently experienced oxidation processes which eukaryotic cells were not capable of performing.

But James McInerney and Mary O'Connell write, "The distribution of genes formerly thought to be eukaryote-specific is patchy.
STEPHENS CITY - For thousands of parents, a child's struggle keeping up in school is an every-day reality. The Arrowsmith Program aims to help parents and students get the help they need to make the process of learning both enjoyable and successful.
In 1993, one year after McClintock's death, Martienssen and his colleagues found what they were looking for: the first mutant eukaryote that was defective in DNA methylation. The plants, which carried a mutation in what the researchers named the ...
He said nuclear pore complexes were important in transporting molecules between the nucleus containing the DNA and the rest of the cell contents in eukaryote organisms. "They are dotted over the surface of the membranes separating the nucleus from the ...
Metagenomic data generally contain a higher proportion of prokaryotic than eukaryotic DNA sequences, said Baker. Consequently, among the remaining 4,500 or so protein families that still have no structural models, many are eukaryote-specific. "Now ...

"The things we thought made a eukaryote a eukaryote, we're now finding in these new archaea," coauthor Brett Baker, an assistant professor at the University of Texas Marine Science Institute, said in a press release.
OXYGEN OASIS Oxygen was abundant enough for complex life-forms such as this 1.4-billion-year-old fossilized eukaryote to thrive around 2.3 billion years ago, new research suggests.

... of strong seasonality, sub-zero temperatures and extended periods of darkness was largely unknown. The genome sequence from Fragilariopsis cylindrus represents the first complete genome of a polar eukaryote -- a 'higher' organism with complex cells.
Approximately 2 billion years later, the domain Eukarya appears. Eukaryotes are multicellular organisms that evolved rapidly over time and gave way to the animals, fungi, and protists that we see today.
Using phylogenomics, they discovered a strong phylogenetic association between ASGARD lineages and eukaryotes that placed the eukaryote lineage in close proximity to the ASGARD superphylum. Next, to investigate the emergence of eukaryotic gene ...
'Ik denk dat hij heeft bewezen dat de eerste eukaryote cel uit een archaeon is ontstaan. Hij komt hier opnieuw met sterk bewijs dat hij de voorouder van de eukaryoten op het spoor is.' Alleen als het gaat om de indeling van het leven in twee, in plaats ...
Trump Takes Questions: The president-elect this morning held his first press conference in six months, in which he announced a new plan to address his conflicts of interest and then conceded for the first time that Russia was likely involved in ...
In addition to bacteria which are prokaryotes, a eukaryote like the probiotic yeast Saccharomyces boulardii could also be used.
Mitochondria supply eukaryotic cells with energy in the form of adenosine triphosphate and are often called "the powerhouse of the cell" as a result.
The slime mould in the study is not a plant, it's not an animal and it's not a fungus: it's a single-cell organism known as a eukaryote. It's name means "many-headed slime" and it prefers cool, moist terrains such as in the decaying logs and trees of ...
One of the main questions is whether Berkeley's disclosed invention/original patent filing easily translates bacteria to eukaryote cells. "If that is the case, then the invention was disclosed in the Berkeley patent, and Broad/Zhang patents would be in ...

Researchers at the Max Planck Institute for Medical Research in Heidelberg have now discovered a new type of antiviral defence mechanism in a single-celled eukaryote by which one virus conveys adaptive immunity to the host against another virus, albeit ...
According to Science Magazine, on one hand, there's Harvard and MIT's Broad Institute where Feng Zhang was the first to file patents using CRISPR to edit eukaryote cells. On the other corner is Jennifer Doudna of University of California, Berkeley ...
They lined up early Monday morning for ringside seats at the most sensational scientific showdown in the modern era. The moment the doors opened, lawyers, reporters and hedge fund investors raced for a spot in the cramped, windowless U.S.
Research that a chemical signal from a bacterium sends this eukaryote, S. rosetta, into a mating frenzy, a finding that raises the possibility that environment bacteria or bacterial symbionts regulate mating in animals.
