Number of premature deaths worldwide caused by consumption in G20 nations

Number of premature deaths worldwide caused by consumption in G20 nations
The haze that blurs a blue sky or a beautiful skyline is caused by particulate matter, often made from pollution, less than 2.5 microns wide. Despite their microscopic size, PM2.5 are responsible for more than 4 million premature deaths every year. A new study shows that the pollution caused by consumption in the world's biggest economies leads to half of those deaths.

The silent build-up to a super-eruption

The silent build-up to a super-eruption
It is estimated that about 5-10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake Toba in Sumatra and has caused two super-eruptions in the last one million years. But when will the next one be? Will there be any warning signs? To answer these questions, an international team of geologists developed an analysis of the levels of uranium and lead in zircons -- a mineral typically found in explosive volcanic eruptions -- to determine how long it took the volcano to prepare for its super-eruptions.

Study shows how 1.5°C temperature rise can cause significant changes in coastal species

Study shows how 1.5°C temperature rise can cause significant changes in coastal species
As COP26 leaders gather in the UK, new research shows a temperature increase of around 1.5°C -- just under the maximum target agreed at the COP23 Paris meeting in 2017 -- can have a marked impact on algae and animal species living on our coastlines.

What’s down there? WHOI study shows environmental DNA is a reliable way to learn about migration from the ocean twilight zone

What’s down there? WHOI study shows environmental DNA is a reliable way to learn about migration from the ocean twilight zone
The mid-ocean 'twilight zone' holds the key to several tantalizing questions about the marine food web and carbon-sequestering capacity of the ocean. But studying this vast and remote area is extremely difficult. Many inhabitants of the twilight zone are easily destroyed during sampling -- or are quick to avoid any disturbance -- so it's difficult to sample them with traditional nets. Advances in acoustics have enabled more accurate estimates of biomass, but questions about the diversity and distribution of species within that biomass remain unanswered.

New type of nerve cell discovered in the retina

New type of nerve cell discovered in the retina
Scientists have discovered a new type of nerve cell, or neuron, in the retina. In the central nervous system a complex circuitry of neurons communicate with each other to relay sensory and motor information; so-called interneurons serve as intermediaries in the chain of communication.

The 5:2 diet: A good choice for gestational diabetes

The 5:2 diet: A good choice for gestational diabetes
Weight loss after gestational diabetes can prevent the onset of type 2 diabetes. Yet finding the most effective way to lose weight and keep it off can be a challenge, especially for mothers with a new baby. Now, new research suggests that the popular 5:2 or intermittent fasting diet is just as effective as a conventional energy-restricting diet, enabling women greater choice and flexibility when it comes to weight loss.

Trapping spins with sound

Trapping spins with sound
Color centers are lattice defects in crystals that can capture one or more additional electrons. The spin of these electrons is very sensitive to external electric and magnetic fields -- and to sound. Researchers are now reporting the selective manipulation of electron spins in both their ground and excited states with sound. Their approach opens the path to new methods for processing quantum information inaccessible so far.

Noninvasive imaging strategy detects dangerous blood clots in the body

Noninvasive imaging strategy detects dangerous blood clots in the body
Investigators have developed and tested a targeted contrast agent that can detect blood clots in the hearts of patients with atrial fibrillation, or an irregular heartbeat. The strategy could be used to find clots in other parts of the body as well, such as in vessels that, when blocked, can lead to stroke.
