Is masturbation the new cold & flu medicine?

Achieving orgasm through masturbation provides a rush of feel-good hormones (such as dopamine, serotonin and oxytocin) and can re-balance our levels of cortisol (a stress-inducing hormone). This helps our immune system function at a higher level.

Earth's early magnetic field was stronger than we thought

The magnetic field that first formed around Earth was even stronger than scientists previously believed, new research suggests. Deep within Earth, swirling liquid iron generates our planet's protective magnetic field. This magnetic field is invisible but is vital for life on Earth's surface: it shields the planet from harmful solar wind and cosmic rays from the sun. Given the importance of the ma

Scientists examine bacterial cannibalism

Researchers from Sechenov University and their colleagues summarised the results of various studies devoted to a process that can be described as bacterial cannibalism. Why some microorganisms start to kill their relatives of the same species and whether we can use this phenomenon to combat infectious diseases is explained in the article published in Antibiotics.

Mayo Clinic Doctor: Coronavirus Is "Basically at a Pandemic Now"

The Chinese coronavirus outbreak might not have been a pandemic just one week ago — but it certainly looks like one now. The virus originated in Wuhan, China, in late 2019. Though it quickly spread to other nations , health experts in late January still considered it to be an epidemic given that most of the people affected were still in one place: China. Since then, however, the World Health Orga

Tailor-made vaccines could almost halve rates of serious bacterial disease

New research has found that rates of disease caused by the bacterium Streptococcus pneumoniae could be substantially reduced by changing our approach to vaccination. Researchers combined genomic data, models of bacterial evolution and predictive modelling to identify how vaccines could be optimized for specific age groups, geographic regions and communities of bacteria.

The secret life of microbes: Molecules in a deep-sea symbiosis

Mussels in the deep sea can only survive there thanks to symbiotic bacteria living inside of them. Researchers have now succeeded for the first time in simultaneously identifying individual bacteria in the symbiosis and measuring which metabolites they convert. This enables a new understanding of many biological processes.

How and when spines changed in mammalian evolution

Researchers compared modern and ancient animals to explore how mammalian vertebrae have evolved into sophisticated physical structures that can carry out multiple functions. The comparison between complex spine of cats, the more uniform spine of lizard, and CT scans of synapsid fossils showed that the evolution of functions (e.g. bending, twisting) is driven by both selective pressures/behavior an
