Although loggerhead sea turtles return to the same beach where they hatched to lay their eggs, a new study by a USF professor finds individual females lay numerous clutches of eggs in locations miles apart from each other to increase the chance that some of their offspring will survive.
A study published in the journal "Scientific Reports" found that some females lay as many as six clutches as far as six miles apart during the same breeding season.
Maybe space is tight in your home and you share a remote office with your spouse.
Or your partner asks you to step away from work to watch the children because they have an important call to jump on. Then you may wonder, 'Well, what makes his/her job more important than mine!'
There have been no shortage of conflicts arising from the era of COVID-19, and that includes the challenges at home between married couples.
Washington and Chicago, January 28, 2021--The American Educational Research Association (AERA) and the Spencer Foundation have released a report, Voices from the Field: The Impact of COVID-19 on Early Career Scholars and Doctoral Students, that shares findings from focus groups conducted in spring 2020. The report, available on the AERA and Spencer websites, is part of an ongoing initiative by the two organizations to assess the pressing needs facing scholars and doctoral students during the pandemic and ways to address these needs.
After analyzing the genomes of more than one-quarter of a million military veterans, a team of scientists, led by researchers at University of California San Diego, Veterans Affairs San Diego Healthcare System (VASDHS), Yale University and West Haven VA, have identified 18 specific, fixed positions on chromosomes (known as loci) that appear associated with post-traumatic stress disorder (PTSD).
HOUSTON - (Jan. 28, 2021) - Like a wrench that gums up the gears, a common anesthetic keeps the motor proteins in your cells from making their rounds.
This is not necessarily a bad thing, but how it works has been a mystery until now.
Researchers at Rice's Center for Theoretical Biological Physics (CTBP) detail the mechanism that allows propofol -- the general anesthetic injected to knock you out before surgery -- to halt the movement of kinesin proteins that deliver cargoes along microtubules to the far reaches of cells.
WACO, Texas (Jan. 28, 2021) - An organization that projects an ethical face but whose managers fail to respond to internal ethical situations sends mixed messages to its employees, which can lead to a lack of employees' moral courage and an increase in unethical behavior, according to a study led by a Baylor University researcher.
The emergence of SARS-CoV-2 virus variants that are adding twists in the battle against COVID-19 highlight the need for better genomic monitoring of the virus, says Katia Koelle, associate professor of biology at Emory University.
Housing instability and homelessness are widely understood to have an impact on health, and certain housing problems have been linked to specific childhood health conditions, such as mold with asthma. But it has not been clear how overall housing quality may affect children--especially those who are at risk from other social determinants of health such as food insecurity or poverty.
As states and municipalities begin to roll out mass vaccination campaigns, some people have dared to ask: When will it be safe to resume "normal" activities again? For those in most parts of the United States, the risk of COVID-19 infection remains extremely high.
A University of Otago study explored factors which influence Americans' levels of concern over climate change, providing discussion on how those factors could impact mitigation efforts.
A key thread of the research examined the ability of people to visualize the future. Results showed that while 74 per cent of respondents were concerned about climate change, only 29 per cent discussed lower carbon options when asked to describe travel in the year 2050.
Scientists are opening new windows into understanding more about the constantly shifting evolutionary arms race between viruses and the hosts they seek to infect. Host organisms and pathogens are in a perennial chess match to exploit each other's weaknesses.
Such research holds tantalizing clues for human health since the immune system is on constant alert to deploy counter measures against new viral attacks. But unleashing too much of a defensive response can lead to self-inflicted tissue damage and disease.
Scientists have created a new way to detect the proteins that make up the pandemic coronavirus, as well as antibodies against it. They designed protein-based biosensors that glow when mixed with components of the virus or specific COVID-19 antibodies. This breakthrough could enable faster and more widespread testing in the near future. The research appears in Nature.
New research from the University of Sheffield has found being overweight is an additional burden on brain health and it may exacerbate Alzheimer's disease.
The pioneering multimodal neuroimaging study revealed obesity may contribute toward neural tissue vulnerability, whilst maintaining a healthy weight in mild Alzheimer's disease dementia could help to preserve brain structure.
The findings, published in The Journal of Alzheimer's Disease Reports, also highlight the impact being overweight in mid-life could have on brain health in older age.
An interdisciplinary team of the Institut national de la recherche scientifique (INRS) used an innovative imaging technique for a better understanding of motor deficits in Amyotrophic Lateral Sclerosis (ALS). The researchers were able to follow the escape behaviour of normal and disease zebrafish models, in 3D. Their results have recently been published in Optica, the flagship journal of the Optical Society (OSA).
Air pollution is a key risk factor for cardiovascular disease, and a major contributor to the global burden of disease. Long-term exposure to air pollution has also been linked to an increased risk of death from COVID-19. This dangerous "triple threat" of air pollution, COVID-19 and cardiovascular disease should be taken seriously, warn major health authorities.
