Unsettling currents: Warm water flowing beneath the 'Doomsday Glacier' April 9, 2021

Researchers have been able to obtain data from underneath Thwaites Glacier, also known as the 'Doomsday Glacier'. They find that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating ice flow.

Brain disease transmitted by tick bites may be treatable April 9, 2021

The virus that causes tick-borne encephalitis appears to trick the immune system, misdirecting it into producing inferior antibodies. But new research shows some people produce more potent antibodies, providing hope for treatment.

Abrupt ice age climate changes behaved like cascading dominoes April 9, 2021

Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades. When certain parts of the climate system changed, other parts of the climate system followed like a series of dominos toppling in succession. Today, sea-ice extent is being […]

Preseismic atmospheric radon anomaly associated with 2018 northern Osaka earthquake April 9, 2021

The concentration of the radioactive element radon is known to change in the ground before and after earthquakes. Previous studies have shown elevated radon levels in the atmosphere before the mainshock of a large inland earthquake due to foreshock activity and slow slip.

Metabolic changes in fat tissue in obesity associated with adverse health effects April 9, 2021

A twin study indicates that the machinery responsible for energy handling in fat tissue is working poorly in obesity. In the study, a clear reduction was seen in the activity of mitochondrial genes in obesity in fat tissue, while similar genome-level change in muscle mitochondria was minor. A link with adverse health effects was identified […]

Glass injection molding April 9, 2021

Researchers succeed in producing rapid, cost-effective and environmentally friendly material.

A sulfosugar from green vegetables promotes the growth of important gut bacteria April 9, 2021

A team of scientists has analyzed how microbes in the gut process the plant-based, sulfur-containing sugar sulfoquinovose. Their study discovered that specialized bacteria cooperate in the utilization of the sulfosugar, producing hydrogen sulfide. This gas has disparate effects on human health: at low concentrations, it has an anti-inflammatory effect, while increased amounts of hydrogen sulfide […]
