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.

The COVID-19 pandemic has strongly impacted our sleep and dream activity. In a recent study published in the Journal of Sleep Research, people had a higher number of awakenings, a harder time falling asleep, higher dream recall, and more lucid dreams during lockdown than after lockdown.

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.

New research published in the European Journal of Clinical Investigation identifies cardiovascular test results that might help to identify patients hospitalized with COVID-19 who face an especially high risk of dying.

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.

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.

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.

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.

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.

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.

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).

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.

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.

More than 1.5 million children around the world are estimated to have lost at least one parent, custodial grandparent, or grandparent who lived with them due to death related to COVID-19 during the first 14 months of the pandemic, according to a study published today in The Lancet.

An estimated 1.5 million children worldwide have experienced the death of a parent, custodial grandparent, or other relative who cared for them, as a result of COVID-19, according to a new study published in The Lancet.

New research published in Anaesthesia (a journal of the Association of Anaesthetists) by researchers from the University of Bristol can help to improve the efficiency of surgery and help tackle the growing backlog of surgery caused by the COVID-19 pandemic.

Research from Cornell University has revealed a new form of bargaining power among Chinese platform-based food delivery workers, who conduct invisible mini-strikes by logging out of apps and airing grievances over WeChat.

A new fiber, made by genetically engineered bacteria in the lab of Fuzhong Zhang, is stronger than steel and tougher than Kevlar.

The in-house development of a novel SARS-CoV-2 test, creation of the Molecular Diagnostics Lab at the Fralin Biomedical Research Institute, and their importance to public health are chronicled in a new article in Nature Communications.

Scientists from the IKBFU with colleagues obtained calcium chelidonate via a semisynthesis. This substance accelerates the transformation of stem cells into osteoblasts - its use is promising as a treatment for bone diseases. A plant, Saussurea controversa, used in medicine since ancient times, served as a source for synthesis.
