Preeclampsia is a mysterious condition that occurs in about one of 10 pregnancies without any early warning signs. After 20 weeks or more of normal blood pressure during the pregnancy, patients with preeclampsia will begin to experience elevated blood pressure and may also have increased levels of protein in their urine due to hypertension reducing the filtering power of the kidneys. Prolonged...

New research has revealed a previously unknown process through which pathogens are able to defeat a cell's defense mechanisms with physical force. The discovery represents a potential game-changer in the fight against intracellular pathogens, which cause infectious diseases such as tuberculosis, malaria and chlamydia.

A new study shows that dopamine release in the human brain plays a crucial role in encoding both reward and punishment prediction errors. This means that dopamine is involved in the process of learning from both positive and negative experiences, allowing the brain to adjust and adapt its behavior based on the outcomes of these experiences.

In a step toward more autonomous soft robots and wearable technologies, researchers have created a device that uses color to simultaneously sense multiple mechanical and temperature stimuli.

Some nonnative plants cultivated in public gardens or arboretums are escaping to become invasive in wild forests.

Societies and political structures, like the humans they serve, appear to become more fragile as they age, according to an analysis of hundreds of pre-modern societies. A new study, which holds implications for the modern world, provides the first quantitative support for the theory that the resilience of political states decreases over time. 

Scientists are testing a novel technology to treat endodontic diseases more effectively through tissue regeneration instead of root canal therapy. Because the technology promotes formation of the type of stem cells that can differentiate into dentin (tooth), bone, cartilage or fat, it has huge potential for the field of regenerative medicine beyond the tissues in the teeth. It could be used to...

How do you create strong, yet quick-release connections between living and non-living tissues? This is a question that continues to puzzle bioengineers who aim to create materials that bond together for advanced biomedical applications. Looking to nature for inspiration, this research zeroed in on the marine mussel byssus, a fibrous holdfast, which these bivalve mollusks use to anchor themselves...

Incorporating human tastes into artificial intelligence makes it easier for wine buyers thirsting for the right wine. Researchers have shown that AI can accurately predict individual wine preferences. The researchers expect that nourishing machines with human sensory experiences will continue to grow.   

A simple-to-apply, needle-free vaccine patch is being developed to protect people from the potentially deadly mosquito-borne Zika virus.

Researchers give medieval Cambridge residents the 'Richard III treatment' to reveal hard-knock lives of those in the city during its famous university's early years. Study of over 400 remains from a hospital cemetery shows spectrum of medieval poverty, and suggests that some of Cambridge University's earliest scholars ended up in penury.   

An international multidisciplinary team consisting of solar physicists, geophysicists, and historians from nine countries analysed observations of an extreme solar-terrestrial storm reported in historical records from February 1872. Their findings confirm that a moderate sunspot group triggered one of the largest magnetic storms ever recorded, almost covering the entire night sky with colourful...

A team of scientists has emphasized that -- surprisingly -- there is currently no formally agreed way of defining the current level of global warming relevant to the Paris Agreement.

A new semiconductor architecture integrates traditional electronics with photonic, or light, components could have application in advanced radar, satellites, wireless networks and 6G telecommunications. And it provides a pathway for a local semiconductor industry.
