Due to temperature inversions in winter, pollutants are trapped in the valleys to such an extent that soot and fine dust could reach alarming levels even in small villages, as they otherwise occur mainly in the centers of congested metropolises.

Researchers have created a heart-healthy, lower sodium version of traditional Chinese cuisine that was appetizing, affordable and significantly lowered blood pressure among adults diagnosed with hypertension. The heart-healthy Chinese diet reduced sodium intake in half, from nearly 6,000 mg daily to about 3,000 mg daily, and featured reduced fat, increased protein and carbohydrates, twice as much dietary fiber and increased potassium. People with high blood pressure may benefit from adopting a similar heart-healthy, lower sodium diet.

Friends enjoy being reached out to more than we think

People consistently underestimate how much others in their social circle might appreciate an unexpected phone call, text or email just to say hello, and the more surprising the connection, the greater the appreciation, according to new research.

Education system 'neglecting the importance of plants'

People are becoming 'disconnected from the botanical world' at a time when plants could help solve global environmental problems, warn a group of research scientists. They say the problem has been exacerbated by schools and universities reducing their teaching of basic plant science, including plant identification and ecology. They describe a self-accelerating cycle which risks '...the extinction of botanical education,' where biology is taught predominantly by people with research interests in animal science.

Molecules boosting plant immunity identified

Researchers have discovered natural cellular molecules that drive critical plant immune responses. These compounds have all the hallmarks of being small messengers tailored by plants to turn on key defense-control hubs. Harnessing these insights may allow scientists and plant breeders to design molecules that make plants, including many important crop species, more resistant to disease.

Functioning of antibodies in autoimmune encephalitis deciphered

Using a state-of-the-art method, researchers have succeeded for the first time at unraveling the effects of autoimmune antibodies, that are directed against the brain, in detail at the atomic level. To this end, they studied two antibodies that dock to so-called GABA-A receptors in one variant of autoimmune encephalitis. Their findings on the structural mechanisms are an important step towards the development of effective therapies -- and they also pave the way for further promising investigations using the new method.

Online art viewing can improve well-being

Viewing art while visiting galleries and museums can have powerful effects on an individual's mood, stress and well-being. But does the same hold true for viewing art in digital space? A new study investigated whether engaging with art online also has this effect. Their conclusion: a short three-minute visit to an online art or cultural exhibition also shows significant positive effects on subjective well-being.

A new giant dinosaur gives insight into why many prehistoric meat-eaters had such tiny arms

An international team has discovered a new big, meat-eating dinosaur, dubbed Meraxes gigas, that provides clues about the evolution and anatomy of predatory dinosaurs such as the Carcharodontosaurus and Tyrannosaurus rex. Meraxes measured around 36 feet from snout to tail tip and weighed approximately 9,000 pounds.

The beginning of life: The early embryo is in the driver's seat

One often thinks that the early embryo is fragile and needs support. However, at the earliest stages of development, it has the power to feed the future placenta and instructs the uterus so that it can nest. Using 'blastoids', in vitro embryo models formed with stem cells, scientists have shown that the earliest molecular signals that induce placental development and prepare the uterus come from the embryo itself.

Case solved: The biosynthesis of strychnine elucidated

A research team has disclosed the complete biosynthetic pathway for the formation of strychnine in the plant species Strychnos nux-vomica (poison nut). The researchers identified all genes involved in the biosynthesis of strychnine and other metabolites and expressed them in the model plant Nicotiana benthamiana. This enabled them to show that these extremely complex and pharmacologically important molecules can be synthesized using 'metabolic engineering' methods.
