Over one million acres of tribal land submerged by dams in the US 

Over one million acres of tribal land submerged by dams in the US 
2023-08-09
(Press-News.org) Dam constructions have flooded over 1.13 million acres of tribal land in the US contributing to the historic and ongoing struggle against land dispossession for Indigenous peoples in the United States. New research, published in Environmental Research Letters, has identified that a region of tribal land larger than the state of Rhode Island has been submerged by dams in the US. The findings raise concerns about the destruction of ecosystems, cultural heritage, and livelihoods. 



The new study shows that dams have significantly contributed to land loss of Native people, a factor that has not been fully quantified until now. Over the centuries, colonial settlers and the federal government have acquired over two billion acres from Native nations through various policies, including forced removal, allotment, and the reservation system. The study considers data from federal Indian reservations and Oklahoma Tribal Statistical Areas (OTSAs) alongside the locations of nearly 8000 dams across the United States and the size of their reservoirs. The research reveals that 424 dams have flooded 1.13 million acres of tribal land in the US. 



Heather Randell, Assistant Professor of Rural Sociology and Demography at Penn State University, says: “The consequences of dam-induced land loss are far-reaching. The disruption of aquatic and terrestrial ecosystems not only devastates natural resources but also destroys culturally significant sites. The impact on local communities' livelihoods and displacement from their ancestral lands is equally severe.” 



Recommendations proposed by the research team include the prioritization of dam removal wherever feasible, along with exploring alternatives such as tribal ownership or funding for dam repairs and improvements in cases where removal is not viable. 



"In the wake of recent federal legislation addressing aging infrastructure in the United States, it is important to prioritize removing dams that have flooded tribal land," Randell continues. "This is an opportunity to address historical land dispossession and to respect the sovereignty and rights of Indigenous communities."

Does access to assisted suicide affect trends of conventional suicide among patients with cancer?

2023-08-09
An analysis published in Cancer Medicine reveals the trends of self-initiated deaths—including assisted suicide (AS) and conventional suicide (CS)—in Switzerland over a 20-year period, focusing on people who suffered from cancer. Although supporters of assisted dying state that access to AS should lead to a reduction in violent CS, the study’s findings do not confirm this assumption. The situations and motivations for cancer-associated CS seem to be clearly different from those for cancer-related AS. In Switzerland, assisting in a suicide is not punishable as long as it does not serve selfish motives. ...

Researchers identify protein that may help protect against osteoporosis

2023-08-09
New research published in The FASEB Journal indicates that increasing the expression of a particular gene may help to prevent bone loss associated with postmenopausal osteoporosis. For the study, investigators examined which genes are involved in turning precursor cells called bone marrow–derived mesenchymal stem cells (BMSCs) into cells that play a crucial role in bone formation. The screen identified a gene that encodes high mobility group AT-hook 1 (Hmga1), a protein that controls the expression of a variety of other genes. In experiments conducted in rats, expression of Hmga1 increased during bone formation but decreased when rats’ ovaries were removed ...

Tool predicts a patient’s risk of developing psoriatic arthritis

2023-08-09
In research published in Arthritis & Rheumatology, investigators developed and validated a tool called PRESTO that identifies patients with psoriasis who face an elevated risk for developing psoriatic arthritis and may therefore benefit from preventive therapies. Among 635 patients with psoriasis followed in the University of Toronto psoriasis cohort, 51 and 71 developed psoriatic arthritis during 1-year and 5-year follow-up periods, respectively. The risk of developing psoriatic arthritis within 1 year was higher in patients with younger age; male sex; family history of psoriasis; back stiffness; nail pitting (dents, ...

Loss of a particular protein causes growth defects in mice and humans

2023-08-09
Through next-generation sequencing, investigators have identified a mutation in the TMCO3 gene in two sisters with short stature. The research, which is published in the Journal of Bone and Mineral Research, also revealed that the TMCO3 protein is expressed by chondrocytes, cells responsible for bone growth, and that it regulates expression of two other proteins known to control bone growth (parathyroid hormone-related protein and Indian hedgehog). TMCO3 appears to transport protons in exchange for potassium across a protein packaging organelle within cells. The scientists confirmed that the mutation in TMCO3 was responsible for the sisters’ ...

Huge tipping events dominated the evolution of the climate system

Huge tipping events dominated the evolution of the climate system
2023-08-09
An analysis of the hierarchy of tipping points suggests that during the last 66 million years two events set the scene for further climate tipping and for the evolution of the climate system in particular. If the anthropogenic climate change of today leads to complete deglaciation, the evolution of Earth's climate will be influenced on a geological time scale, the authors suggest. The work by Denis-Didier Rousseau, Université Montpellier, France, Witold Bagniewski, Ecole Normale Supérieure, Paris, France, and Valerio Lucarini, University of Reading, UK is published in Scientific Reports and is part of the European TiPES project on tipping points ...

Electrical signals between skin cells may influence melanoma initiation

2023-08-09
PHILADELPHIA – The transfer of a neurotransmitter from one type of skin cell to another (melanocytes to keratinocytes) altered electrical activity and promoted melanoma initiation in preclinical models, according to results published in Cancer Discovery, a journal of the American Association for Cancer Research. Melanoma is a deadly form of skin cancer that develops in melanin-containing skin cells known as melanocytes. An intrinsic feature of melanocytes is their ability to secrete melanin-containing vesicles to surrounding skin ...

The voices of indigenous peoples and local communities as an important part of the climate fight

The voices of indigenous peoples and local communities as an important part of the climate fight
2023-08-09
Coinciding with the International Day of Indigenous Peoples, an ICTA-UAB study calls for indigenous peoples' in-depth knowledge of climate change to be considered. Indigenous Peoples and local communities around the world have a rich and extensive general knowledge of climate change impacts and possible ways to adapt. This knowledge should be recognised by both science and climate policy. This is the main conclusion of an international study led by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) which has spent five years analysing and providing detailed data on how Indigenous Peoples and local communities ...

Having a bad hair day? Blame your genes!

Having a bad hair day? Blame your genes!
2023-08-09
Philadelphia, August 9, 2023 – The first gene mapping study on human scalp hair whorls not only shows that hair whorl direction has a genetic basis, but also that it is affected by multiple genes. Four associated genetic variants that are likely to influence hair whorl direction are identified, as reported in the Journal of Investigative Dermatology, published by Elsevier. A hair whorl is a patch of hair growing in a circular pattern around a point specified by hair follicle orientations. As an easily observed human trait, scalp hair whorl pattern is typically defined by the whorl number (single ...

New survey confirms need for more menopause education in residency programs

2023-08-09
CLEVELAND, Ohio (August 9, 2023)—Despite the fact that nearly 90 million women in the United States are projected to be postmenopausal by 2060, menopause remains low on the priority list of many residency programs. A new survey reveals the lack of a standardized menopause curriculum and limited access to menopause educational resources for residents. Results of the survey are published online today in Menopause, the journal of The Menopause Society.   Because women today are living longer, it is not surprising that there are a record number of postmenopausal women. And, that number is only expected ...

Booster shot being developed to avoid recapturing koalas to fight Chlamydia disease
2023-08-09
A booster vaccine using implant technology for koalas is being developed by QUT researchers in the fight against the deadly Chlamydia disease. The new technology is designed to avoid problems for wild koalas and wildlife handlers having to recapture or hold the animals for 30 days, to receive a second immunisation. Koala chlamydia is a bacterial infection and is one of the leading causes of death for Australian koalas. QUT researchers have been successfully testing a two-shot vaccine on an isolated wild koala colony ...
