Boston, MA - Greater adherence to a variety of healthy eating patterns was associated with a lower risk of cardiovascular disease (CVD), according to new research led by Harvard T.H. Chan School of Public Health. The findings add support for the 2015-2020 Dietary Guidelines for Americans, which focus on healthy eating patterns rather than individual ingredients and nutrients to better account for diverse cultural and personal food traditions and preferences.
By analysing the different layers of bacterial gene expression during pathogen infection of a plant host, Kenichi Tsuda and colleagues from the Max Planck Institute for Plant Breeding Research in Cologne, Germany and Huazhong Agricultural University in Wuhan, China have revealed new insights into bacterial gene regulation as well as the strategies employed by plants to target key bacterial processes.
New research published in the journal Coral Reefs revealed unexpectedly high growth rates for deep water photosynthetic corals. The study, led by Samuel Kahng, affiliate graduate faculty in the University of Hawai'i at Mānoa School of Ocean and Earth Science and Technology (SOEST), alters the assumption that deep corals living on the brink of darkness grow extremely slowly.
Polarization, conspiracy theories, fake news: What people see on the Internet is largely determined by the opaque algorithms of just a few corporations. That's a worrying development for democratic societies. But online environments could be designed in ways that promote autonomy and transparency, thereby fostering the positive potential of the Internet.
Researchers discover what's behind nature's perhaps largest erection - which is not that big
PLANT BIOLOGY In the plant kingdom, the sexual organ of a male pollen grain grows up to a thousand times its own length as it sniffs its way forth to a female egg cell to deliver its two sperm cells. Now researchers at the University of Copenhagen have advanced the understanding of what makes pollen 'penises', called pollen tubes, grow. The newfound knowledge may prove valuable to understanding human nerve cells.

A donated heart can now be transported and preserved for longer than what has previously been possible. The new method, which consists of a specially designed heart box, was used for a transplant for the first time as early as the summer of 2017. Now it has been evaluated in a first clinical study, and the results are published in Nature Communications.
The results from the study show clear signs of improvement when the new method is used.
Low physical function and low muscle mass after hip fracture increased the risk for accelerated bone deterioration in older hip fracture patients. Acknowledgement of the risk factors is important for bone health and overall recovery.
"Substantial decrements in physical function, muscle and bone strength occur after hip fracture, which markedly increase the risk for a subsequent fracture," says Tuuli Suominen, a PhD student at the Gerontology Research Center, Faculty of Sport and Health Sciences at the University of Jyväskylä.
Researchers have used artificial intelligence to reduce the 'communication gap' for nonverbal people with motor disabilities who rely on computers to converse with others.
The team, from the University of Cambridge and the University of Dundee, developed a new context-aware method that reduces this communication gap by eliminating between 50% and 96% of the keystrokes the person has to type to communicate.
An international research team has used new X-ray techniques to describe how the architecture of healthy human bones is built up. The team has uncovered a hitherto unknown structure in healthy bones.
The human bone is a wonderful and fantastic biological material. Bone tissue is highly specialised, with a structure optimised for specific functions in the body. Healthy bones are strong, they have a high carrying capacity, and they are hard to break.
BOSTON (June 15, 2020)-- A new, multi-ethnic study found older adults with low vitamin K levels were more likely to die within 13 years compared to those whose vitamin K levels were adequate. The results suggest vitamin K, a nutrient found in leafy greens and vegetable oils, may have protective health benefits as we age, according to the researchers.
Programming quantum computers is becoming easier: computer scientists at ETH Zurich have designed the first programming language that can be used to program quantum computers as simply, reliably and safely as classical computers. "Programming quantum computers is still a challenge for researchers," says Martin Vechev, computer science professor in ETH's Secure, Reliable and Intelligent Systems Lab (SRI), "which is why I'm so excited that we can now continue ETH Zurich's tradition in the development of quantum computers and programming languages."
Transmission of COVID-19 from mother to baby during pregnancy is uncommon, and the rate of infection is no greater when the baby is born vaginally, breastfed or allowed contact with the mother, according to a new study.
The research also found that babies that did test positive for COVID-19, were mostly asymptomatic.
The findings are published in BJOG: An International Journal of Obstetrics and Gynaecology.
Berkeley -- In 2005, University of California, Berkeley, researchers made the surprising discovery that making conjoined twins out of young and old mice -- such that they share blood and organs -- can rejuvenate tissues and reverse the signs of aging in the old mice. The finding sparked a flurry of research into whether a youngster's blood might contain special proteins or molecules that could serve as a "fountain of youth" for mice and humans alike.
WASHINGTON, June 15--Black and female assistant principals are systematically delayed and denied promotion to principal, compared to their White or male counterparts, despite having equivalent qualifications and more experience on average, according to a new study. The findings were published in June in AERA Open, a peer-reviewed, open access journal of the American Educational Research Association.
PITTSBURGH (June 15, 2020) -- A cell's membrane acts as a natural shield, a fence around the cell that protects and contains it. It mediates processes that let nutrients through and let waste out, and it acts as a physical barrier to the entry of toxic substances and pathogens, like the viruses SARS-CoV-1 and SARS-CoV-2, the one that causes COVID-19.
