Biophysicists reveal molecular mechanism behind light-driven sodium pumping

An international research team has for the first time obtained the structure of the light-sensitive sodium-pumping KR2 protein in its active state.

Study hints a mechanistic link between sex and stress response in microbes

Why is sex so popular? The question of why so many organisms reproduce sexually has mystified evolutionary biologists since before Darwin, who wrote that "The whole subject is as yet hidden in darkness."

International collaborators propose a new ranking scheme to classify SARS-CoV-2

In November of 2019--likely, even earlier--a tiny entity measuring just a few hundred billionths of a meter in diameter began to tear apart human society on a global scale.

First detailed map of transcriptome and epitranscriptome for novel coronavirus (SARS-CoV-2)

A team of researchers has come out with the first detailed map of the transcriptome and epitranscriptome of the virulent SARS-CoV-2 that causes COVID-19 disease, the illness that has become a pandemic ravaging both developed and less developed countries of the world. The study, published in the journal Cell in April 2020, may assist in the development of new vaccines and therapeutics.

Researchers show possibility to control cell bioenergetics by changing mitochondria content

Researchers at the University of California, Irvine have shown that they can give cells a short-term boost of energy through mitochondrial transplantation.

Study uncovers large, giant viruses that belong to NCLDV supergroup

While the microbes in a single drop of water could outnumber a small city's population, the number of viruses in the same drop-;the vast majority not harmful to humans could be even larger.

New method reveals how giant viruses infect amoeba

Host cells infected with giant viruses behave in a unique manner. To gain deeper insight into the infection mechanism of giant viruses, scientists at Tokyo University of Science developed a specialized algorithm that can track the movement of host cells.

Doughnut-shaped circles of ecDNA provide tumor cells with a malignant twist

Deoxyribonucleic acid or DNA encodes information, not only in its sequence but also in its shape.

Researchers discover key similarities between human and archaea chromosomes

A study led by researchers at Indiana University is the first to find similarities between the organization of chromosomes in humans and archaea.

Parasites could have originated from transmissable cancers

Researchers have presented a controversial new theory suggesting that transmissible cancers could eventually evolve into their own multicellular species.

Study reveals the complexities of viral evolution

Comparing a living cell to a virus is a bit like comparing the Sistine Chapel to a backyard dog house. Lacking the intricate machinery of living cells, viruses represent biology stripped down to an extreme level. They are the true minimalists of the biological world.

New research could help design algae that produces fuels and cleanup chemicals

It's a case of grand larceny that could lead to new fuels and cleanup chemicals. Ten species of red algae stole about 1 percent of their genes from bacteria to cope with toxic metals and salt stress in hot springs, according to a study in the journal eLife.

Research could lead to new treatments for people with autoimmune disorders

The immune system is programmed to rid the body of biological bad guys--like viruses and dangerous bacteria--but its precision isn't guaranteed. In the tens of millions of Americans suffering from autoimmune diseases, the system mistakes normal cells for malicious invaders, prompting the body to engage in self-destructive behavior.

CircRNAs bind to dsRNA-activated protein kinase which is linked to innate immunity

Covalently closed circular RNAs are produced by precursor mRNA back-splicing the exons of thousands of genes in eukaryotes.

Designer organelles in living mammalian cells can build synthetic proteins

A research team led by biophysical chemist Professor Edward Lemke has engineered a designer organelle in a living mammalian cell in a new complex biological translation process. The created membraneless organelle can build proteins from natural and synthetic amino acids carrying new functionalities.
