Loops, loops, and more loops: This is how your DNA gets organized

Added: 23.02.2018 1:08 | 15 views | 0 comments

A living cell is able to neatly package a big jumble of DNA into chromosomes while preparing for cell division. For over a century, scientists have been puzzled for decades on how the process works. Researchers now managed for the first time to isolate and film the process, and witnessed -- in real time -- how a single protein complex called condensin reels in DNA to extrude a loop.

How bats carry viruses without getting sick

Added: 23.02.2018 1:08 | 12 views | 0 comments

Bats are known to harbor highly pathogenic viruses like Ebola or Marburg and yet they do not show clinical signs of disease. Scientists find that in bats, an antiviral immune pathway called the STING-interferon pathway is dampened, and bats can maintain just enough defense against illness without triggering a heightened immune reaction.

A look at the space between mouse brain cells

Added: 23.02.2018 1:08 | 12 views | 0 comments

Between the brain's neurons and glial cells is a critical but understudied structure that's been called neuroscience's final frontier: the extracellular space. With a new imaging paradigm, scientists can now see into and study this complex fluid-filled matrix.

Cancer risk associated with key epigenetic changes occurring through normal aging process

Added: 23.02.2018 1:08 | 15 views | 0 comments

Some scientists have hypothesized that tumor-promoting changes in cells during cancer development -- particularly an epigenetic change involving DNA methylation -- arise from rogue cells escaping a natural cell deterioration process called senescence. Now, researchers have demonstrated that instead, tumor-associated epigenetic states evolve erratically during early stages of tumor development, eventually selecting for a subset of genes that undergo the most changes during normal aging and in early tumor development.

Neuroscientists discover a brain signal that indicates whether speech has been understood

Added: 23.02.2018 0:59 | 3 views | 0 comments

The presence or absence of a unique brain signal after a listener has heard some speech indicates whether or not that listener has understood what has been said. The discovery has a number of practical applications, including tracking language development, assessing brain function post-injury, and confirming whether important instructions have been understood in high-pressure jobs.

New neurons in the adult brain are involved in sensory learning

Added: 23.02.2018 0:59 | 4 views | 0 comments

Scientists have demonstrated that the new neurons produced in adults react preferentially to reward-related sensory stimuli and help speed up the association between sensory information and reward. Adult-born neurons therefore play an important role in both the identification of a sensory stimulus and the positive value associated with that sensory experience. The neurons generated shortly after birth are unable to perform this function.

In living color: Seeing cells from outside the body with synthetic bioluminescence

Added: 23.02.2018 0:38 | 16 views | 0 comments

Glowing creatures like fireflies and jellyfish are captivating to look at but also a boon for science, as their bioluminescent molecules contribute to visualizing a host of biological processes. Now, scientists have supercharged these molecules, making them hundreds of times brighter in deep tissues and allowing for imaging of cells from outside the body. The bioengineered light source was used to track cancer cells in mice and brain-cell activity in monkeys, but its applications extend beyond the lab.

The Australian government's plan for the biocontrol of the common carp presents several risks

Added: 22.02.2018 23:41 | 2 views | 0 comments

Scientists are calling on the Australian authorities to review their decision to introduce the carp herpes virus as a way to combat the common carp having colonized the country's rivers. They not only believe that this measure will be ineffective but that it also represents a risk to ecosystems.
