It is a genus of about 130 species of flowering plants and unique because of the size of its composite inflorescence
The first large-scale study of the risks that countries face from dependence on water, energy and land resources has found that globalisation may be decreasing, rather than increasing, the security of global supply chains.
Adults with severe obesity (BMI >35) and a prior heart attack who undergo weight-reduction surgery may lower their risk of a second heart attack, major cardiovascular event, heart failure and death. The effect weight-reduction surgery had on the patients' weight, blood pressure, cholesterol and A1C (a Type 2 diabetes marker) seems to play a role in decreasing the risk of heart attack and death.
Over-activity in a single brain region called the subgenual anterior cingulate cortex (sgACC) underlies several key symptoms of mood and anxiety disorders, but an antidepressant only successfully treats some of the symptoms. A new study suggests that sgACC is a crucial region in depression and anxiety, and targeted treatment based on a patient's symptoms could lead to better outcomes.
Nearly 30% of U.S. adults younger than 45 don't know all five of the most common stroke symptoms, according to a recent survey. Hispanic adults, people not born in the U.S. and less educated young adults were among the most likely to be unaware of stroke symptoms. Stroke incidence and hospitalizations are rising among young adults in the U.S.
A new study using biomimetic fish-like robots shows that swimming closely together offers fish hydrodynamic benefits.
What do you have on your 2020 Bingo Card? Wildfire, heat wave, global pandemic, or flooding? If it's flooding, then it's a good bet it will happen in many places in the U.S. sometime during the year.
The COVID-19 pandemic started earlier than previously thought in New York City and Long Island by dozens of people infected mostly with strains from Europe. A new analysis also shows that most of the spread was within the community, as opposed to coming from people who had traveled.
Through an effort to characterize the color receptors in the eyes of the fruit fly Drosophila melanogaster, researchers discovered the spectrum of light it can see deviates significantly from what was previously recorded.
Why is fish smell unpleasant for some people?Researchers have found that some people carry a mutation in a particular gene that makes fish odour less

Here is some of the most interesting research to have appeared in top science journals last week
Because of the sudden turn of events, scientists won’t know how much the sample capsule holds until it’s back on Earth.
Two days after touching down on asteroid Bennu, NASA's OSIRIS-REx mission team received on Thursday, Oct. 22, images that confirm the spacecraft has collected more than enough material to meet one of its main mission requirements -- acquiring at least 2 ounces (60 grams) of the asteroid's surface material.
Scientists have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules that help shield HIV from the immune system. Mapping these shields will give researchers a more complete understanding of why antibodies react to some spots on the virus but not others, and may shape the design of new vaccines that target the most vulnerable sites on viruses.
Through intricate experiments designed to account for sex-specific differences, scientists have zeroed-in on certain changes in the brain that may be responsible for driving alcohol abuse among people with PTSD. In studies with rodents, researchers found that males and females exhibit their own distinct symptoms and brain features of PTSD and alcohol use disorder. Such differences are not typically accounted for in laboratory-based studies yet could lead to more successful clinical treatments.
Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a research team. The researchers believe these metals could change the ocean ecosystem, though it's unclear whether it would be for better or worse.
