Cells need to keep their genomic DNA unharmed to stay healthy and research scientists were able to visualize the process of DNA replication and damage directly in cells with an unprecedented detail. They discovered a fundamental mechanism of how proteins protect chromosomes while undergoing DNA replication, which relies on a protein called RPA. Read more: http://ow.ly/r4wV0

Imagine a hospital room, door handle or kitchen countertop that is free from bacteria—and not one drop of disinfectant or boiling water or dose of microwaves has been needed to zap the germs. That is the idea behind a startling discovery made by scientists in Australia. The germ-killer is black silicon, a substance discovered accidentally in the 1990s. Under an electron microscope, its surface is a forest of spikes just 500 nanometres (500 billionths of a metre) high that rip open the cell walls of any bacterium which comes into contact, the scientists found.

In first-aid situations, wounds must be quickly and effectively closed to stop blood loss and prevent infection. For treatment on arrival in a hospital, the temporary seal must be reopened, which often causes additional damage to the injured tissue. In the journal Angewandte Chemie, American scientists have now introduced a novel gel for sealing wounds. The gel can later be dissolved and gently removed. Read more: http://ow.ly/rqskT

It was less than a year ago that scientists first applied CRISPR, a genome-editing technique, to human cells. In short order, the technique has taken off like wildfire. And now, two papers appearing in Cell Stem Cell on December 5 show that CRISPR can be used to rewrite genetic defects to effectively cure diseases in mice and human stem cells.

@RexRed,

Recently Rex it's reported that some of the physical constants' values depend on those of others, suggesting a critical relationship. Leads one to wonder if eventually it will be discovered that all the constants are so interrelated, dependent upon one another so to speak, leading to eventual speculation that after all the Universe wasn't created by a God using some set of arbitrary rules that favored evolution of the humanoid, but instead that all the "rules" reflect necessary phenomena, that things are the way they are and happen the way they do because they have to

A beaky, crested dinosaur nicknamed the "chicken from hell" has been discovered in both North and South Dakota.

This was not a "chicken" you'd want to stumble across in the barnyard: The new dino, dubbed Anzu wyliei, was about 11 feet (3.5 meters) long and about 10 feet (3 m) tall. Read more: http://ow.ly/uM2s3

oblolly pines are pleasant conifers that grow throughout the Southeast US, and are probably the most commercially important tree in the South. Denizens of the lowlands, they are also found in clay soils, quickly reclaim old fields, and have a fragrant smell that some say resembles rosemary (or gin). But they have another surprising trait: Their genome is the largest on record. Read more: http://www.popsci.com/article/science/scientists-sequence-largest-genome-date

Very curious discovery.

@RexRed,

Thanks Rex for that. The pines' might be much bigger but don't you suppose ours are more complex

One might think so but nature is the one that ultimately decides. Smile

I see you posted this quite a while back so it's not very relevant but it is a topic of great interest to me.

I think cosmologist have gotten dark matter wrong. My thought process is based on the fact that gravity is limited to the speed of light. Now in the presence of matter, space is warped and as the stars move around the galaxy they leave behind a warped space trough similar to how a boat moves through water. This lag of gravity is what they are calling dark matter. It is why we don't see anything there. The objects have long since moved but the impacts of the gravity remain behind and slowly dissipate. I just thought I would share my ideas on this.

This physicist, Lawrence Krauss is one of the world's leading experts and has a new book out on the subject.

Much of this is over my head but I still trudge through it because I have much interest in the subject. Smile

Yeah I have seen this video, I have watched it multiple times. It is a good lecture.

Doesn't change what I mentioned though, and I bet you in a few years they will be saying what I pointed out. On a side note it even accounts for the expansion as well, but it becomes a little complicated to explain how. It has to do with static space and time differentials. A quick run down..

The time of static space and that of moving matter are moving at different rates. Static space time is moving much faster than that of moving matter. So what happens is when matter comes into the presence of static space the time differentials need to cancel out but they can't so it causes the matter to push on the static space like trying to push together two magnets with the same poles facing each other. Since static space surrounds all matter it causes a constant inflation effect. But this only happens where the matter is moving and the faster that matter is moving the larger the impact.

Rex I agree most wholeheartedly. Most of the world's problems would immediately disappear if only the rest of 'em came suddenly to realize what a remarkable thing we have

, about which I've long wondered. If you yourself Rex have accessed these I wonder if you might briefly summarize his answer, to save so many of us a disappointment
