Consuming higher amounts of Vitamin D -- mainly from dietary sources -- may help protect against developing young-onset colorectal cancer or precancerous colon polyps, according to a new study.
Multicellular algae discovered in an Early Cambrian formation
The Cambrian period, which occurred around 541–485 million years ago, is known for its explosive biological diversification. In warm oceans, the planet's earliest eukaryotes began to thrive and diversify. A major contributing factor to the acceleration of life and the development of early metazoans is thought to be an increasingly efficient food web, created largely by algae. These new...
Gender revolution in who holds the purse strings
New research has uncovered considerable class differences in the gender revolution of who holds the purse strings among British couples.
Orioles adapt the location of their wintering grounds to weather conditions
The ability to adjust to changing environmental conditions is an essential prerequisite for species to cope with climate change. Using stable isotope analysis, a team of scientists led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) now unraveled the link between wintering destinations of Eurasian Golden Oriole migrations and rainfall intensities in potential wintering grounds...
Co-production connects research and action for sustainability
Research on complex sustainability issues produces a great deal of knowledge and advice. But do these also connect to the real world? The answer may be found in co-production: don't put one researcher or computer at the helm, but rather collaboratively produce knowledge and action with a diversity of people pursuing change in the world. Scientists argue this in a new study that outlines six ways...
UK medical schools must teach about climate crisis, say students
Extreme weather events widen existing inequalities and traumatise victims while climate anxiety affects mental healthMedical students are demanding their schools include the climate crisis as a core component of the curriculum, as the intensifying climate emergency highlights the corresponding health crisis.Hannah Chase, a final year medical student at Oxford said the sense of urgency hit home...
Build your strategic defense against cybercriminals
With the rise of ransomware attacks and cybercrime in the headlines week after week, fighting cybercriminals takes a multi-faceted approach that’s not just the realm of the CTO, but of every business leader. There is no time to waste in ensuring that your organization’s cyber-resiliency strategy is on the right path. Join us at CyberSecure, MIT Technology...
Using military language might not be the best approach to COVID and public health
Governments around the world have enacted unprecedented responses to minimize the spread of COVID to preserve both individual health and health systems.
Forget massive seawalls—coastal wetlands offer the best storm protection money can buy
Coastal communities around the world are facing increasing threats from tropical cyclones. Climate change is causing rising sea levels and bigger, more frequent storms.
OO Dra is an Algol-type binary formed through an extremely helium-poor mass accretion
Using data from NASA's TESS satellite, Chinese astronomers have investigated a binary star known as OO Dra. The study found that this object is an Algol-type binary that was formed as a result of an extremely helium-poor mass accretion process. The findings are reported in a paper published August 6 on the arXiv pre-print repository.
Pompeii tomb offers new hints about cultural life in ancient city
Archaeologists in the ancient city of Pompeii have discovered a remarkably well-preserved skeleton during excavations of a tomb that also shed light on the cultural life of the city before it was destroyed by a volcanic eruption in AD...
Charging the true cost of driving to get New Zealanders out of their cars
In light of last week's Intergovernmental Panel on Climate Change report confirming human activity is "unequivocally" driving global warming, here's a striking statistic: in Auckland, road transport modes are responsible for 35% of the city's climate-altering emissions.
Students who are more adaptable do best in remote learning, and it can be taught
The speed and scale of the shift to remote online learning during the COVID-19 pandemic has really tested students' adaptability. Our study of more than 1,500 students at nine Australian high schools during 2020 found strong links between their level of adaptability and how they fared with online learning.
Study: Fire in wet area of the Amazon destroys 27% of trees in up to three years
Even in the wettest parts of the Amazon, the impact of forest fires, which spread through these areas only during extreme droughts, is sufficient to change the characteristics of the vegetation in the coming decades, although it is not as significant as in other parts of the biome.
Novel iron-based catalyst boosts conversion of CO2 to higher alcohols
Higher alcohols (C2+OH), important intermediates for fine chemicals, are mainly produced via petrochemical route, which is energy-intensive and environmentally unfriendly.
Ecosystem responses of grassland to drought
Grassland, as one of the important ecosystems and an ecological barrier in China, is the green production base of animal husbandry. It plays a vital role in maintaining national ecological security, food security and even global ecological balance. However, climate change is expected to lead to more frequent extreme droughts in grassland regions. Yet, the underlying mechanisms of ecosystem...
Cities are making mammals bigger
A new study shows urbanization is causing many mammal species to grow bigger, possibly because of readily available food in places packed with people.
Plant diversity in grasslands: Multi-species swards outperform even in drought conditions
Six-species swards outperformed perennial ryegrass monocultures and were considerably more resistant to drought, research has found.
New research provides clues to developing better intranasal vaccines for COVID-19 and flu

While gut microbiota play a critical role in the induction of adaptive immune responses to influenza virus infection, the role of nasal bacteria in the induction of virus-specific adaptive immunity is less clear. New research explores the role of nasal bacteria and provides clues to developing better intranasal vaccines for flu and COVID-19.
Mutated enzyme weakens connection between brain cells that help control movement
- ScienceDaily
- 21/8/17 14:46
In one type of a rare, inherited genetic disorder that affects control of body movement, scientists have found a mutation in an enzyme impairs communication between neurons and what should be the inherent ability to pick up our pace when we need to run, instead of walk, across the street.
Mechanisms of resistance to drug for triple-negative breast cancer identified
- ScienceDaily
- 21/8/17 14:46
Triple-negative breast cancer cells exposed to the antibody-drug conjugate sacituzumab govitecan may develop resistance to this powerful drug through alterations in both the target of the antibody and the target of the toxic payload. The findings illustrate how uncovering such mechanisms will critically inform strategies to overcome resistance to sacituzumab govitecan.

Scientists have created a new type of catalyst that will lead to new, sustainable ways of making and using molecules and protect the supply of precious metals.
Cracking a mystery of massive black holes and quasars with supercomputer simulations
At the center of galaxies, like our own Milky Way, lie massive black holes surrounded by spinning gas. Some shine brightly, with a continuous supply of fuel, while others go dormant for millions of years, only to reawaken with a serendipitous influx of gas. It remains largely a mystery how gas flows across the universe to feed these massive black holes.
Number of unemployed people across the EU during pandemic remained 'remarkably' stable
Labor markets in Southern Europe and the Baltic States were among those hit hardest last year by the pandemic, according to an Open Access study published in the peer-reviewed journal Applied Economics Letters.
