Now scientists from the Max Planck Institute for Biology of Ageing in Cologne have discovered the way a new letter of this alphabet is used in cells.

søvn og hukommelsen – mangel på søvn hæmmer nye erindringers dannelse

Sleep deprivation handicaps the brain's ability to form new memories, mouse study shows
Studying mice, scientists have fortified evidence that a key purpose of sleep is to recalibrate the brain cells responsible for learning and memory so the animals can 'solidify' lessons learned and use them when they awaken — in the case of nocturnal mice, the next evening.

søvn – billedscanning viser hjernens omstilling under søvn

Sleep research high-resolution images show how the brain resets during sleep
Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: Our synapses — the junctions between nerve cells — grow strong and large during the stimulation of daytime, then shrink by nearly 20 percent while we sleep, creating room for more growth and learning the next day.

You can only learn so much before needing to snooze
Sleep recalibrates the brain’s memory cells, allowing us to solidify what we’ve learned and use it when next awake, new evidence from mice indicates. Sleep deprivation, sleep disorders, and sleeping pills can interfere with the process, researchers from the Johns Hopkins University School of Medicine conclude. “The bottom line is that sleep is not really downtime for the brain.” “Our findings sol

Researchers Tap a Sleep Switch in the BrainFor more than a century, biologists have been studying sleep.

Tiny cavefish may help humans evolve to require very little sleep
We all do it; we all need it—humans and animals alike. Sleep is an essential behavior shared by nearly all animals and disruption of this process is associated with an array of physiological and behavioral deficits. Although there are so many factors contributing to sleep loss, very little is known about the neural basis for interactions between sleep and sensory processing.

Viruses propagate by infecting a host cell and reproducing inside. This not only affects humans and animals, but bacteria as well. This type of virus is called bacteriophage.

telomerer

[Report] TZAP: A telomere-associated protein involved in telomere length control
Telomeres are found at the end of chromosomes and are important for chromosome stability. Here we describe a specific telomere-associated protein: TZAP (telomeric zinc finger–associated protein). TZAP binds preferentially to long telomeres that have a low concentration of shelterin complex, competing with the telomeric-repeat binding factors TRF1 and TRF2. When localized at telomeres, TZAP trigger

telomerer

[Perspective] TZAP or not to zap telomeres
Telomeres play vital roles in genome stability, protecting chromosome ends from degradation and rearrangements. Telomere erosion with aging occurs in most human somatic cells. This limits cellular life span and suppresses uncontrolled proliferation of premalignant cells. On the other hand, short telomeres may prevent continued tissue renewal and contribute to organismal aging. Therefore, maintaini

One way that researchers have overcome some of these drawbacks is using stimuli-responsive polymers.

As a result of climate change, concentrations of the trace element selenium in soils are likely to decrease.

protein der sikrer æg/sæd fusion bruges også ved virusfusion

New link found between sex and viruses
Sexual reproduction and viral infections both rely on a functionally identical protein, according to new research. The protein enables the fusion of two cells, such as a sperm cell and egg cell, or the fusion of a virus with a cell membrane. The discovery suggests that the protein evolved early in the history of life on Earth, and new details about the protein's function could help fight parasitic

proteiner der ikke foldes på bestemt måde

[Perspective] Quantifying protein (dis)order
Twenty-five years ago, Chothia predicted that the structural domains of all proteins can be classified into about 1000 folds (1). Later studies refined this number; however, scientists also found that some proteins or parts of proteins never assume a specific fold. These regions are called intrinsically unstructured or disordered (2). Oncogenes such as p53 or breast cancer 1 (BRCA1) contain long d

psykopater – nyt syn på

Top professional performance through psychopathy
The term “psychopath” is not flattering: such people are considered cold, manipulative, do not feel any remorse and seek thrills without any fear – and all that at other’s expense. A study is now shattering this image. They claim that a certain form of psychopathy can lead to top professional performance, without harming others or the company.

Later, she and her colleagues showed that cells take advantage of this trait to help locate and repair potentially harmful mutations to DNA.

Cystic fibrosis, sickle cell anemia, Huntington's disease and phenylketonuria are all examples of disorders caused by the mutation of a single nucleotide, a building block of DNA. The human DNA consists of approximately 3 billion nucleotides of four types: Adenine (A), cytosine (C), guanine (G), and thymine (T). In some cases, the difference of just one nucleotide can bring serious consequences. S

DNA acts like electrical wire to replicate itself
DNA’s ability to act like an electrical wire plays a part in how it replicates, new research shows. In the early 1990s, Jacqueline Barton, professor of chemistry at Caltech, discovered an unexpected property of DNA—that it can act like an electrical wire to transfer electrons quickly across long distances. Later, she and colleagues showed that cells take advantage of this trait to help locate and

Double food production by 2050? Not so fast
“Food production must double by 2050 to feed the world’s growing population,” is a popular idea, but an inaccurate one, according to new research. Production likely will need to increase between 25 percent and 70 percent to meet 2050 food demand, a study in Bioscience suggests. The data don’t support the assertion that we need to double global crop and animal production by 2050, argues Mitch Hunt

New polymer additive could revolutionize plastics recycling
Only 2 percent of the 78 million tons of manufactured plastics are currently recycled into similar products because polyethylene (PE) and polypropylene (PP), which account for two-thirds of the world's plastics, have different chemical structures and cannot be efficiently repurposed together. That could all change with a new discovery.

How some breast cancer cells return after chemo
Researchers have identified a biochemical chain of events that allows some breast cancer cells to survive chemotherapy and restart tumor growth. The recurrence of cancer stem cells is tied to the drug resistance that develops in many breast tumors. Because of that resistance, the benefits of chemo are short-lived for many patients. Cancer recurrence after chemotherapy is frequently fatal. “These

Crop breeding aims to balance disease resistance with yield; however, single resistance (R) genes can lead to resistance breakdown, and R gene pyramiding may affect growth fitness. Here we report that the rice Pigm locus contains a cluster of genes encoding nucleotide-binding leucine-rich repeat (NLR) receptors that confer durable resistance to the fungus Magnaporthe oryzae without yield penalty.

BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.

Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.

Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
