Morris Animal Foundation-backed research illuminates path to sihek revival

Morris Animal Foundation-backed research illuminates path to sihek revival
2023-10-25
(Press-News.org) DENVER/Oct. 25, 2023 – A recently published paper in Animal Conservation provides crucial insights into the health of sihek, a species eradicated from its native habitat and that may now face threats in captivity. The latest data underscores a stark gender disparity, revealing that female sihek are at greater risk for death and disease than their male counterparts. 

As part of an ongoing Morris Animal Foundation-funded study, researchers at The Zoological Society of London are investigating the health of sihek, also known as the Guam kingfisher. Their work encompasses a range of issues including hatching failure, female health, mortality rates and genetic threats impacting the bird. 

“The sihek is a species on the very brink of being lost forever – and it is only due to the care and expertise of conservation zoos that these birds still exist, giving us a chance to return them to the wild,” said Dr. Amanda Trask, the study’s principal investigator. “Conservationists, zookeepers and scientists working to restore a wild population. They are working at the cutting edge of conservation, and we must continue to review and build upon existing knowledge of their care to ensure that the species has the best possible chance.”

Trask said the research team examined the causes of death in the birds and found differences between males and females. Females succumbed to reproductive diseases – a phenomenon not observed in males. The incidence of reproductive diseases among female sihek was also notably higher than in other avian species. While it’s still unclear why this is occurring, she added that the team’s upcoming research will delve into a potential correlation with increased egg production. Other causes of death, such as nutritional and metabolic diseases, were seen in both males and females, but females tended to succumb at younger ages than males.

Trask thanked the Foundation for supporting her work and looks forward to continuing her support of the international initiative involving Zoos from the Association of Zoos and Aquariums, federal and Guam agencies and non-governmental conservation organizations, to return sihek to the wild.

“The grant has also been essential to develop my career and research interests at the interface between wildlife health and conservation biology,” Trask said. “It has allowed me to continue producing research with direct application to threatened population management strategies and species recovery planning.”

Can insomnia treatment reduce cardiovascular disease risks? $3 million funds study to find out
2023-10-25
INDIANAPOLIS — It’s no secret that a good night’s rest can do wonders for one’s health, but those who struggle with insomnia have a nearly 50% increased risk of cardiovascular disease. One scientist in the School of Science at IUPUI will spend the next five years trying to figure out how those risks can be reduced. Jesse Stewart, a professor of psychology at the school, has received a five-year, $3 million grant from the National Institutes of Health’s National Heart, Lung and Blood Institute for a project named the Strengthening Hearts ...

Higher levels of triglycerides linked to lower risk of dementia

2023-10-25
EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, OCTOBER 25, 2023 MINNEAPOLIS – Older people who have higher levels of triglycerides, a type of fat, may have a lower risk of dementia and a slower cognitive decline over time compared to people who have lower levels, according to new research published in the October 25, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. While the study found a link, it does not prove that higher levels of triglycerides prevent dementia. Triglycerides are fatty acids and are the most common type of fat in the blood. Triglycerides contribute ...

Childhood trauma linked to headaches in adulthood

EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, OCTOBER 25, 2023 MINNEAPOLIS – People who have experienced traumatic events in childhood such as abuse, neglect or household dysfunction may be more likely to experience headache disorders as adults, according to a meta-analysis published in the October 25, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. This research does not prove that such experiences cause headaches; it only shows an association. “Traumatic events in childhood can have ...

New distractibility “d factor” may be linked with ADHD
2023-10-25
In a study of different types of distraction involving more than 1,000 participants, researchers statistically derived a novel measure—dubbed the “d factor”—that could represent a person’s general tendency towards distraction and may be linked with attention-deficit/hyperactivity disorder (ADHD). Han Zhang of the University of Michigan, Ann Arbor, and colleagues present these findings in the open-access journal PLOS ONE on October 25, 2023. Prior research has explored various types of distraction, such as external stimulations, repetitive ...

Deepfake videos during Russian invasion of Ukraine could undermine trust

Deepfake videos during Russian invasion of Ukraine could undermine trust
2023-10-25
A new study explores themes in Twitter discussions of deepfake videos related to the Russian invasion of Ukraine, highlighting the potential for real videos to be mistaken for deepfakes and for deepfakes to fuel conspiracy theories. John Twomey of University College Cork, Ireland, and colleagues present these findings in the open-access journal PLOS ONE on October 25, 2023. Created using artificial intelligence, deepfake videos typically feature a person saying and doing things they never actually did in real life. Deepfake technology has advanced considerably, sparking concerns about its potential harms. ...

In Prehispanic Cancun, immigrants were treated just like Maya locals

In Prehispanic Cancun, immigrants were treated just like Maya locals
2023-10-25
Ancient people immigrated to Cancun Island and were treated just like locals, according to a study published October 25, 2023 in the open-access journal PLOS ONE by Andrea Cucina of the Autonomous University of Yucatan, Mexico and colleagues. The Late Postclassic (AD 1200-1500) in the northern Maya lowlands was a period of major changes, including the development of many settlements along the east coast of the Yucatan Peninsula, influenced in part by expanded trade routes. Previous research has found that these settlements were home to many non-local individuals, but it remains unclear whether these people were treated as “foreigners” ...

Climate change likely impacted human populations in the Neolithic and Bronze Age
2023-10-25
Human populations in Neolithic Europe fluctuated with changing climates, according to a study published October 25, 2023 in the open-access journal PLOS ONE by Ralph Großmann of Kiel University, Germany and colleagues. The archaeological record is a valuable resource for exploring the relationship between humans and the environment, particularly how each is affected by the other. In this study, researchers examined Central European regions rich in archaeological remains and geologic sources of climate data, using these resources to identify correlations between human population trends and climate change. The ...

First ever study of wartime deepfakes reveals their impact on news media
2023-10-25
A first ever study of wartime deepfake videos reveals their impact on news media and outlines implications for social media companies, media organisations and governments.   Deepfakes are artificially manipulated audio-visual material. Most deepfake videos involve the production of a fake ‘face’ constructed by Artificial Intelligence, that is merged with an authentic video, in order to create a video of an event that never really took place. Although fake, they can look convincing and are often produced to imitate or mimic an individual.  Researchers at University ...

Anti-anxiety drug may improve brain cancer survival chances

Anti-anxiety drug may improve brain cancer survival chances
2023-10-25
A new research study shows that cerebrospinal fluid reduces current treatment efficacy in brain cancer and identifies new therapeutic opportunities. Cerebrospinal fluid, the clear colourless liquid that protects the brain, also may be a factor that makes brain cancers resistant to treatment, Australian researchers led by Associate Professor Cedric Bardy at the South Austraila Health and Medical Research Institute (SAHMRI) and Flinders University reveal in the journal Science Advances. Reporting how this occurs, the study in high-profile journal Science Advances shows that a decades-old anti-anxiety drug can improve the effectiveness of chemo-radiotherapy ...
