Closely spaced habitats are more likely to be used by mosquitoes to lay eggs

Patches of standing water that are close together are more likely to be used by mosquitoes to lay eggs in than patches that are farther apart, according to a new study from the University of Georgia. The findings, recently published in Oecologia, have implications for human and animal health.

Mechanisms behind antibiotic resistance captured on video for the first time

Scientists have established the cause of antibiotic-resistance in bacteria on video, and the findings contradict previous beliefs.

Temporal fluctuations in protein concentrations can determine fate of stem cells

How do temporal variations in protein concentrations affect biology? It's a question that biologists have only recently begun to address, and the findings are increasingly showing that random temporal changes in the amount of certain proteins play a direct and significant role on biological processes.

New technique can rapidly image synaptic proteins at high resolution

Our brains contain millions of synapses -- the connections that transmit messages from neuron to neuron. Within these synapses are hundreds of different proteins, and dysfunction of these proteins can lead to conditions such as schizophrenia and autism.

Researchers investigate relationship between immune defenses and body size

What species is better at fighting an infection, a mouse or an elephant? Body size is one of the most noticeable differences among species, but relationships between immune defenses and body size have largely been unstudied.

Scientists use new single-cell genetic technique to tackle potential drug resistance

Using a new technique that can identify genetic profiles of individual cells, University of Notre Dame researchers modeled a breast cancer tumor's potential resistance to a drug, and then identified a drug combination that reversed that resistance.

Monitoring the Human Proteome using diaPASEF

In this interview, Dr. Hannes Röst describes how his lab are using diaPASEF to monitor the human proteome throughout a person's lifetime, and how machine learning could be used to analyze the data.

Reactivating ‘tumor suppressor’ genes could offer new therapeutic approach for cancer

Scientists have developed a method which is able to switch ‘tumor suppressor’ genes back on after they have been silenced by cancer cells.

Improved mapping of genomes from 1,000 Swedish individuals

In so-called whole genome sequencing, surveys are made of the total genome of an individual. It is still relatively rare in healthcare today, but it occurs at an increasing rate, for example in order to make an accurate diagnosis in the case of a rare disease.

Tapeworms need their head for stem cell-driven regeneration

Scientists have identified the stem cells that allow tapeworms to regenerate and found that their location in proximity to the head is essential, according to a new study in eLife.

Ear's tiny outer hair cells regulate sound sensitivity, study shows

The ear’s tiny outer hair cells adjust the sensitivity of neighboring inner hair cells to sound levels rather than acting like an amplifier, suggests a new study published today in eLife.

Mice also fidget like humans while making decisions

Almost everyone fidgets, said Cold Spring Harbor Laboratory Associate Professor Anne Churchland. She referred to a collage of videos she compiled of different people rocking back and forth in their chairs, clicking a pen, shaking their legs.

Study uncovers epigenetic origins for hypersexual disorder

A new study has shown that epigenetic changes lead to overactivity of the hormone oxytocin, and this is a key element in hypersexual disorder.

Discovery provides potential therapeutic target for prostate cancers with PTEN mutation

PTEN, a tumor suppressor gene mutated in approximately 20% of primary prostate cancers, and in as many as 50% of androgen deprivation-resistant prostate cancers, relies on another gene, ARID4B, to function.

Scientists develop method to reactivate tumor suppressor genes 'silenced' by cancer

Scientists at UCL have developed a method to reactivate 'tumor suppressor' genes, which are switched off by cancer cells - a finding which could lead to new targeted biotherapies for cancer.

Researchers uncover fundamental difference in how DNA is held together

Researchers have made a fundamental discovery about the structure of DNA; the structure is held together by water, not hydrogen alone.

Study provides new insight into how cells maintain their identity

In the body's cells, some proteins are of vital importance as to which genes are active or turned off. Now, researchers from the University of Copenhagen and the Memorial Sloan Kettering Cancer Center have discovered which proteins are necessary in order to maintain the proper genetic regulation.
