How do wind turbines impact Golden Eagles?
Results from a study published in Ibis show that how close Golden Eagles will fly to wind turbines depends on habitat suitability inside and outside of a wind farm. Also, the largest impact of wind farms was a loss of Golden Eagle habitat, which could be mitigated by including the study's findings in wind farm planning.

Innovative program entertains and teaches children about fish migration
It's important to communicate about hard-to-see and complex environmental topics and issues with young people. In an article published in People and Nature, an international team reflects on the group's creation of the Shout Trout Workout, a lyric poem, comic, and music video for children aged 8-14 years old designed to entertain, engage, and enrich learning about migratory fishes and aquatic environments.

How readily does COVID-19 spread on school buses?
Although in-school transmission of COVID-19 among K-12 students is low when safeguards are in place, the risk of acquiring COVID-19 during school bus transportation is unclear. A study published in the Journal of School Health reports on the bus transport experience of an independent school in Virginia.

The frequency of misattributed paternity in Sweden
The frequency of misattributed paternity, where the assumed father is not the biological father, is low and decreasing in Sweden, according to an analysis published in the Journal of Internal Medicine of 1.95 million family units with children born mainly between 1950 and 1990.

Scientists identify protein markers related to the most common form of leukemia
Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world. New research published in the Journal of Leukocyte Biology reveals that certain protein markers may indicate which patients have stable forms of CLL and which have more aggressive types.

Hundreds of chemicals, many in consumer products, could increase breast cancer risk
a new study shows that several hundred common chemicals, including pesticides, ingredients in consumer products, food additives, and drinking water contaminants, could increase the risk of breast cancer by causing cells in breast tissue to produce more of the hormones estrogen or progesterone.

Urgent need for anti-smoking campaigns to continue after pregnancy
Curtin University research has found quit support for smoking mothers should continue even after their first babies are born, given that many of those women will become pregnant again, and that quitting can substantially reduce the risk of future preterm births.

More exercise and fewer hours watching TV cuts sleep apnoea risk
Being more physically active and spending fewer hours per day sitting watching TV is linked to a substantially lower risk of developing obstructive sleep apnoea (OSA), according to new research published in the European Respiratory Journal. The study of more than 138,000 US men and women is the first to simultaneously evaluate physical activity and sedentary behaviour in relation to OSA risk.

New 3D images of shark intestines show they function like Nikola Tesla's valve
For more than a century, researchers have relied on flat sketches of sharks' digestive systems to discern how they function -- and how what they eat and excrete impacts other species in the ocean. Now, researchers have produced a series of high-resolution, 3D scans of intestines from nearly three dozen shark species that will advance the understanding of how sharks eat and digest their food.

Thinking about getting pregnant? First check your risks for heart disease
A new study of more than 18 million pregnancies found a woman's heart health before she becomes pregnant is strongly related to her likelihood of experiencing a complication during her pregnancy or labor. The study examined the presence of four cardiovascular risk factors in women before they became pregnant: smoking, unhealthy body weight, hypertension and diabetes. Adverse pregnancy outcomes include maternal intensive care unit (ICU) admission, preterm birth, low birthweight and fetal death.

SuperBIT: A low-cost balloon-borne telescope to rival Hubble
Durham, Toronto and Princeton Universities have teamed up with NASA and the Canadian Space Agency to build a new kind of astronomical telescope. SuperBIT flies above 99.5% of the Earth's atmosphere, carried by a helium balloon the size of a football stadium. The telescope will make its operational debut next April and when deployed should obtain high-resolution images rivalling those of the Hubble Space Telescope.

Planetary shields will buckle under stellar winds from their dying stars
Any life identified on planets orbiting white dwarf stars almost certainly evolved after the star's death, says a new study led by the University of Warwick that reveals the consequences of the intense and furious stellar winds that will batter a planet as its star is dying. The research is published in Monthly Notices of the Royal Astronomical Society, and lead author Dr Dimitri Veras will present it today (21 July) at the online National Astronomy Meeting (NAM 2021).

Women's heart health is strongly related to pregnancy outcomes
A study of more than 18 million pregnancies has shown a strong and graded relationship between women's heart health and pregnancy outcomes. The research is published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC). The researchers examined the presence of four risk factors for cardiovascular disease in women prior to pregnancy: unhealthy body weight, smoking, hypertension and diabetes.

DNA from 93-year-old butterfly confirms the first US case of human-led insect extinction
The Xerces blue butterfly is generally accepted as the first American insect species destroyed by urban development, but there are lingering questions about whether it was really a species to begin with, or just a sub-population of another common butterfly. In a new study, researchers analyzed the DNA of a 93-year-old Xerces blue specimen in museum collections, and confirmed that it was a unique species.
