Discovery of new Hepatitis C Virus mechanism

Researchers have uncovered the mechanisms that suppress the propagation of the hepatitis C virus with the potential of improving pathological liver conditions. Using model mice, they confirmed that when a certain enzyme is inhibited, HCV particle production is reduced leading to an improvement of pathological liver conditions. Show More Summary

How do pesticides protect crops?

New research could lead to the fine-tuning of pesticide formulations to further increase crop yield. The findings also show a way to develop advanced performance formulations which will interact reversibly with plant surfaces and will leave their protective cuticles unharmed.

Toxins in e-cig vapor increase with heat and device use

Electronic cigarettes, or e-cigs, have grown in popularity as an alternative to traditional cigarette smoking. But health experts and consumer advocates have raised concerns over their safety. Now scientists report new measurements of potentially toxic compounds in e-cigarette vapor and factors that affect these levels.

Torn-apart galaxy may be exacting revenge on the Milky Way

The satellite Sagittarius dwarf galaxy may have been massive enough to warp the disc of our galaxy – payback for the fact the Milky Way is ripping it apart

Old planets always get too hot or cold for life in the end

Searching for alien life on planets orbiting older stars may be fruitless - they nearly always lose their liquid water with time

Archaeologists Make Surprise Find Under Mayan Temple

When researchers grew concerned about underground anomalies detected near the Mayan ruins of Palenque in Mexico, they began a dig to figure out whether the pyramid was in danger of collapse. This week, researchers announced that what they found was no anomaly but rather a small canal system, reports the...

Did the LIGO gravitational waves originate from primordial black holes?

Binary black holes recently discovered by the LIGO-Virgo collaboration could be primordial entities that formed just after the Big Bang, report Japanese astrophysicists. If further data support this observation, it could mark the first confirmed finding of a primordial black hole, guiding theories about the beginnings of the universe.

New Zealand wren DNA analysis reshapes geological theory

A DNA analysis of living and extinct species of mysterious New Zealand wrens may change theories around the country's geological and evolutionary past.

Vitamin D levels predict risk of brain decline in Chinese elderly

Low vitamin D levels has been associated with increased subsequent risk of cognitive decline and impairment in the Chinese elderly, a new study shows.

World first demo of labyrinth magnetic-domain-optical Q-switched laser

Researchers have fabricated the first magneto-optical (MO) Q-switched laser. Unlike electro-optic (EO) and acousto-optic (AO) effects, MO effects had not previously been used in Q-switched lasers, even though they are also very well-known phenomena. The fabricated MO Q-switched laser contributes to the development of compact high-power lasers.

Two neonicotinoid insecticides may have inadvertent contraceptive effects on male honey bees

Male honey bees, called drones, can be affected by two neonicotinoid insecticides by reducing male honey bee lifespan and number of living sperm. Both insecticides are currently partially banned in Europe. Now researchers are calling for more thorough environmental risk assessments of these neonicotinoids.

Online intervention helps sustain weight loss

Obesity is a common problem that can result in a number of health problems including type 2 diabetes, heart disease, joint problems and stroke. Aside from changes to diet and increased levels of physical activity, behavioral counseling...Show More Summary

Low physical capacity second only to smoking as highest death risk

A 45 year study in middle-aged men has shown that the impact of low physical capacity on risk of death is second only to smoking. The study was designed to investigate risk factors for cardiovascular disease and mortality.

Astronomers uncover hidden stellar birthplace

Astronomers have uncovered a hidden stellar birthplace in a nearby spiral galaxy, using a telescope in Chile. The results show that the speed of star formation in the center of the galaxy - and other galaxies like it - may be much higher than previously thought.

Gene therapy developed for muscle wasting

A discovery could save millions of people suffering from muscle wasting disease.

The hot attraction of gold

Gold had long been considered a non-magnetic metal. But researchers recently discovered that gold can in fact be magnetized by applying heat.

The eyes are the window into the brain

Insight into how neurons in the cerebellum respond to rapid eye movements may provide clues for modern medical technology.

Murusraptor barrosaensis: a new megaraptorid Theropod From Cretaceous Argentina

A new species of megaraptorid dinosaur discovered in Patagonia may help discern the evolutionary origins of the megaraptorid clade, according to a study published July 20, 2016 in the open-access journal PLOS ONE by Rodolfo Coria from...Show More Summary
