Research published in the British Journal of Developmental Psychology indicates that the COVID-19 pandemic and lockdown had largely positive impacts on gender identity development in trans and gender diverse youth. For the study, 295 transgender and gender diverse U.S. youth, ages 13–22 years, were asked the open-ended question “How has the COVID pandemic changed or affected your own understanding of your gender identity?” Responses revealed several themes. The most prevalent was “time for identity development,” ...

Older adults with multiple chronic conditions may face a high risk of kidney function decline, according to new research published in the Journal of the American Geriatrics Society. In the study, 3,094 older individuals from the Swedish National Study on Aging and Care in Kungsholmen were followed for 15 years. There was an independent dose-response relationship between the number of chronic conditions and kidney function decline, so that as the number of chronic conditions increased, kidney function decline became more likely and steeper. When considering the makeup of conditions rather than just ...

It aims to maintain the highest ethical standards for donors by upholding the principles of informed consent, oversight, and dignity. The report emphasizes the importance of ensuring potential donors and their families ...

Many infants in Sweden are given milk cereal drinks, ready-to-mix liquid drink complements to breast milk, after six months of age. New research in Acta Paediatrica found evidence that these products are linked to early rapid weight gain but not to higher anthropometric measures—such as body mass index or waist-to-height ratio—later in childhood. In the study of 1,333 children from three communities in Western Sweden, physical characteristics and food habits were collected in 2007–2008 family surveys. Follow-up data for 656 children were collected in 2013–2014. At baseline, 820 (62%) of the 658 boys and 675 girls consumed milk cereal drinks, and 229 (18%) had early ...

Some people can’t imagine a dog barking or a police siren. Songs can’t get stuck in their heads. They have no inner voices. ‘Anauralia’ was proposed in 2021 by scientists from Waipapa Taumata Rau, University of Auckland to describe the little-known condition of a silent mind. Now, as their investigations into the phenomenon continue, the University will host a global conference on sounds imagined in the mind, an event intended not just for scientists but also philosophers, musicians, poets and writers. ‘Mind’s ...

The increasing number of strokes and subsequent rehabilitation has highlighted the growing need for effective care strategies. Serious side effects, such as motor paralysis, can be challenging to mend, but the recent incorporation of robots into treatment has shown promise. Automated robots repeatedly provide the proper movements necessary to recover motor function. However, to ensure appropriate care tailored to the degree of motor paralysis, knowledge of robots and rehabilitation is needed. Osaka Metropolitan University Professor Takashi Takebayashi of the Graduate School of Rehabilitation Science led a team in collecting data from ...

CLEVELAND, Ohio (Dec 18, 2024)–A woman’s sex drive may diminish with age—partially because of problems with genitourinary symptoms during the menopause transition. Yet, some older women maintain very active sex lives. Why? A new study suggests that one difference could be sexual identity, with nonheterosexual women more likely to report better sexual functioning, despite menopause. Results of the study are published online today in Menopause, the journal of The Menopause Society. An estimated 25% to 85% of postmenopausal women report challenges ...

Researchers at the University of Hawai‘i at Mānoa recently discovered that a virus, FloV-SA2, encodes one of the proteins needed to make ribosomes, the central engines in all cells that translate genetic information into proteins, the building blocks of life. This is the first eukaryotic virus (a virus that infects eukaryotes, such as plants, animals, fungi) found to encode such a protein.  Viruses are packets of genetic material surrounded by a protein coating. They replicate by getting inside of a cell where they take over the cell’s replication machinery and direct it to make more viruses. ...

In higher plants and green algae, Photosystem II (PSII) usually combines with Light Harvesting Complex II (LHCII) to form the PSII-LHCII supercomplex. Under low-light conditions, the PSII-LHCII supercomplexes are organized laterally into higher-order PSII-LHCII megacomplexes and semi-crystalline arrays to optimize photosynthetic efficiency. A recent collaborative study has deciphered the cryo-EM structure of the spinach type I PSII-LHCII megacomplex, providing insights into the principles of higher-order ...

This system eliminates the need for complicated drug ‘carriers’, making it potentially more useful in a range of applications. The research has been published in Science Advances and was led by Melbourne Laureate Professor and NHMRC Leadership Fellow Frank Caruso, from the Department of ...

Drinking a small or moderate amount of wine may lower the risk of serious cardiovascular disease in people at a higher risk who are following a Mediterranean diet, according to research published in the European Heart Journal [1] today (Wednesday).   Previous studies on the effects of wine on cardiovascular health have produced inconsistent results. This may be in part because research often relies on people reporting how much wine they drink. Instead, in the new study, researchers measured the amount of a chemical, called tartaric acid, in participants’ urine. Researchers say this is an “objective and reliable measure” of wine consumption.   The ...

Apes orphaned by the illegal trade in bushmeat and pets can overcome trauma and develop social abilities like those of their mother-reared peers. A new study led by Durham University, UK, looked at the effects of rehabilitation by the world’s only bonobo sanctuary on the social and emotional development of orphaned bonobo apes across a 10-year period. Bonobos are our closest living relatives, along with chimpanzees, and are only found in the Democratic Republic of Congo. The early life trauma of maternal loss and the deprivation from being captured by humans can have long lasting negative effects on bonobos’ social abilities. Researchers wanted to see what impact rehabilitation ...

A new material for high density data storage can be erased and recycled in a more efficient and sustainable way, providing a potential alternative to hard disk drives, solid-state drives and flash memory in future. The low-cost polymer stores data as ‘dents’, making a miniscule code in patterns, with the indents just nanometers in size – promising to store more data than typical hard disk drives. The new Flinders University Chalker Lab polymer, which can have the information in it wiped in seconds by short bursts of heat and be reused several times, is described in a major new ...

Another advance has been made by experts in nano-scale chemistry to propel further development of sustainable and efficient generation of hydrogen from water using solar power. In a new international collaborative study – led by Flinders University with collaborators in South Australia, the US and Germany – experts have identified a novel solar cell process to potentially use in future technologies for photocatalytic water splitting in green hydrogen production.  Combined with a catalyst – developed by US research led by Professor Paul Maggard – for water splitting, the study found the new class of kinetically stable ...

CORVALLIS, Ore. – Hiking by yourself deep in a forest and similar episodes of intense solitude are not as likely to restore energy and enhance social connectedness as less complete forms of solitude, such as reading in a café or listening to Spotify while commuting, research by Oregon State University suggests. The findings are important because of solitude’s role in building connectedness, a key factor in a person’s overall health picture. According to the U.S. Centers for Disease Control and Prevention, strong social ties are linked with a longer lifespan, better mental health and a lower risk of serious illness, including heart ...

AGU press contact:   Liza Lester, +1 (202) 777-7494, news@agu.org (UTC-5 hours)  Researcher contact:  Victoria Donovan, University of Florida, victoria.donovan@ufl.edu (UTC-5 hours) WASHINGTON — The eastern U.S. has more trees and shrubs than three decades ago. This growth, driven by processes such as tree and understory infilling in unmanaged forests, is helping fuel wildfires, contributing to changing fire regimes in the eastern half of the country, according to a new study. Some parts of the eastern and southeastern United States have experienced a tenfold increase ...

Isolated atoms in free space radiate energy at their own individual pace. However, atoms in an optical cavity interact with the photons bouncing back and forth from the cavity mirrors, and by doing so, they coordinate their photon emission and radiate collectively, all in sync. This enhanced light emission before all the atoms reach the ground state is known as superradiance. Interestingly, if an external laser is used to excite the atoms inside the cavity moderately, the absorption of light by the atoms and the collective emission can ...

Women opting for a medical abortion at home are often advised that the procedure is likely to be no more painful than period cramps, suggest the results of a survey, carried out by the British Pregnancy Advisory Service (BPAS), and published online in the journal BMJ Sexual & Reproductive Health.   This leaves many women unprepared for the intensity of the pain they experience, with some survey respondents saying they would have chosen a different option, had they known. More realistic and patient centred information needs to be provided to enable women to make ...

Cumulative exposure to air pollution over several years is linked to a heightened risk of admission to hospital for mental/behavioural and physical illness, finds Scottish research published in the open access journal BMJ Open.   Stricter environmental restrictions are needed to curb the impact on secondary care, conclude the researchers. Previously published research on the health effects of long term exposure to ambient air pollution has tended to emphasise deaths rather than hospital admissions, and physical, rather than mental, ill ...

In a groundbreaking study published this week in The Journal of Physiology, biologists at the Marine Mammal Research Program (MMRP) at the University of Hawaiʻi at Manoa Hawaiʻi Institute of Marine Biology (HIMB) used drone imagery to advance understanding of how lactating humpback whales and their calves fare as they traverse the Pacific Ocean. Recent declines in North Pacific humpback whale reproduction and survival of calves highlight an urgent need to understand how mother-calf pairs expend energy across their migratory ...
