Study shows how ocean virus captures the metabolism of carbon-storing bacteria

Below the surface of the ocean, a virus is stealing the metabolism of the most abundant organism present on Earth. That might be attractive to those who breathe above the ocean’s surface.

Damped circadian oscillations observed in the absence of KaiA protein in cyanobacterium

Circadian rhythms are driven by a highly autonomous, self-sustaining circadian clock in our cells, telling us when to sleep or wake up in a 24-hour cycle.

Study discovers how protein inhibits tumor development in mice

Proteins are found throughout our cells and regulate a lot of biological processes that are important for our survival.

Nanodevices give unprecedented peek into how cells change with time

For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development.

New minimally invasive method allows cells to be sampled over time

At any given moment, a variety of dynamic processes occur inside a cell, with many developing over time. Because current research methods for gene profiling or protein analysis destroy the cell, study is confined to just that one moment in time, and researchers are unable to return to the cell to examine how things change beyond that snapshot.

The eye launches an immune response in the lens following injury

The lens of the eye is an unusual organ. Unlike most of the body's organs, blood vessels don't reach the lens. If they did, they'd obscure our vision and we wouldn't be able to see. The lack of vasculature led scientists to believe immune cells, which travel via the bloodstream, couldn't get to this part of the body either.

Mechanically rejuvenated fibroblasts show promise in stem cell engineering

Fibroblasts synthesize the collagen, creating the structural framework for animal tissues, and play a significant role in the process of wound healing.

Determining the optimal age of stem cells to restore heart tissue

Biophysicists have successfully established the optimal age of reprogrammed stem cells that are appropriate for restoring heart tissues.

New sequencing method helps map the spatial arrangement of DNA

A sequencing technique helps to map the spatial arrangement of DNA in the cell nucleus, revealing which regions of the genome are at greater risk of mutation.

Next-Generation solar cells pass strict international tests

Australian scientists have for the first time produced a new generation of experimental solar energy cells that pass strict International testing standards.

Researchers design antibody to identify pathogens of Alzheimer's disease

Researchers have found a way to design an antibody that can identify the toxic particles that destroy healthy brain cells - a potential advance in the fight against Alzheimer's disease.

New model mimics early embryonic stages of the human brain

We know a lot about the human brain, but very little about how it is formed. In particular, the stages from the second to the seventh week of embryonic development have so far been virtually unknown territory to brain researchers.

Gene associated with thinness may play a role in resisting weight gain

Some people can remain slim easily, irrespective of their diet, while others might be dieting and working out at the gym to maintain their shape.

Biochemical and computational methods for large-scale protein-arginine methylation analysis

Methylation (namely addition of a methyl group) of arginine amino acid residues of proteins is a post-translational modification (PTM) catalyzed by a family of nine enzymes called Protein Arginine Methyl-Transferases (PRMTs).

Genetic 'memory' of ancestral homelands helps organisms adapt to environmental change

Organisms carry long-term "memories" of their ancestral homelands that help them adapt to environmental change, according to a new study that involved raising chickens on the Tibetan Plateau and an adjacent lowland site.

Nanobowl-stabilized liposomes are less leaky than regular liposomes

For many years, researchers have analyzed the use of liposomes, which are hollow spheres composed of lipid bilayers, to transmit chemotherapy drugs to tumor cells.
