Notice me! Neglected for over a century, Black sea spider crab re-described

Even though recognised in the Mediterranean Sea, the Macropodia czernjawskii spider crab was ignored by scientists (even by its namesake, 19th-century biologist Vladimir Czernyavsky) in the regional faunal accounts of the Black Sea for more than a century. Now, scientists re-describe this, most likely, sole species of the genus to occur in the Black Sea. The finding was published in the...

One in two Americans fear a major health event could lead to bankruptcy

As the COVID-19 pandemic continues to put lives and livelihoods at risk, 1 in 2 Americans say they fear a major health event could lead them to file for bankruptcy, marking a 5% increase since 2019. The new research comes from the West Health-Gallup US Healthcare Study, an ongoing series of surveys on the impact of high healthcare costs on American lives.

Relatives in deep grief can be helped earlier

Many relatives who experience severe long-term grief reactions after bereavement have more frequent contact with their general practitioner already prior to bereavement, as well as a higher consumption of antidepressants and sedatives than those who have fewer critical symptoms of grief over time. This suggests that it may be possible to prevent this by catching this group earlier. This is shown...

RethiNKing which immune cells are the best weapon against lung cancer

Immune cells called 'natural killer' (NK) cells could be a powerful weapon for fighting lung cancer, according to Melbourne researchers.Studying preclinical and patient samples of small cell lung cancer (SCLC), the Walter and Eliza Hall Institute team revealed that NK cells - but not T cells - are essential for slowing the aggressive spread of the cancer. 'Supercharging' the NK cells further...

Revisiting ratios

There's more to seawater than salt. Ocean chemistry is a complex mixture of particles, ions and nutrients. And for over a century, scientists believed that certain ion ratios held relatively constant over space and time.

Scent-sensing cells have a better way to fight influenza

Smell receptors that line the nose get hit by Influenza B just like other cells, but they are able to clear the infection without dying. A new Duke University paper in Cell Reports reveals not only the cells' successful strategy against viral infection, but also the diversity of immune responses from one kind of cell to another.

Scientists discover key regulator of neuron function and survival

Scientists studying neuronal energy metabolism found evidence the loss of an important energy regulator called AMPK in neural stem cells or glial cells called astrocytes causes neuronal death in laboratory rodents. Publishing their findings in Cell Reports, researchers also discovered AMPK loss in neural stem cells or neurons causes spontaneous brain seizures in the animals. The study provides...

Severe Covid-19 despite or even due to the strong immunity

A weak immune response isn't the cause of dangerous lung failure in severe Covid-19 infections. Such infections seem, on the contrary, to be caused by an overreaction of the immune system. This is the conclusion made by a research team from Ruhr-Universität Bochum (RUB) and the university hospital of Duisburg-Essen led by Professor Nina Babel, Head of the Centre for Translational Medicine at...

Swedish workers among Europe's best-paid in late 1800s

In 19th-century Sweden, workers' wages rose faster than in other European countries. By 1900, they were among the highest in Europe, and the steepest rise of all had been for those who earned least. This is shown by new research at Uppsala University: a study published in The Journal of Economic History.
