Earth

The Earth's climate system is largely determined by the differences in temperature between the tropics and the poles. Global warming is likely to cause global atmospheric circulation to change and progressively revert to a situation similar to that of 5,000 to 10,000 years ago. This is the conclusion of a study undertaken by a research team led by Dr. Michael Deininger, the results of which have been published in Nature Communications.

They have shown that certain multi-sectoral mechanisms, such as marine protected areas, are the most effective in reconciling the ecological, economic and social dimensions of this SDG. These results were published in the journal Nature Sustainability on 14 December 2020, and will make it possible to improve operational guidelines for the preservation of the oceans.

Climate change is expected to make many grape-growing regions too hot and dry to produce high-quality wine from traditional varieties. But scientists at the University of California, Davis, have found that wine grape varieties from regions that are more prone to stress have traits that could help them cope with climate change.

The Fatty Acid Research Institute (FARI) has published a new research paper in conjunction with The Cooper Institute on the omega-3s EPA and DHA in fish oil and low density lipoprotein cholesterol (LDL-C).

New research from the University of California San Diego shows that since modern crop varieties were introduced in the developing world starting in 1961, they have substantially reduced infant mortality, especially for male babies and among poor households.

Researchers at the University of Illinois Chicago have published a study showing a promising approach to using drug repurposing to treat genetic diseases.

A team from the UIC Department of Ophthalmology and Visual Sciences published the article, "Gene dosage manipulation alleviates manifestations of hereditary PAX6 haploinsufficiency in mice" in the journal Science Translational Medicine.

The world is getting warmer and warmer - and many organisms native to lower latitudes or elevations are moving higher.

However, novel organisms moving into a new habitat could disturb the ecological balance which has been established over a long period. Plants and herbivores are characterised by long-term co-evolution, shaping both their geographic distribution and the characteristics that they display in their occupied sites.

With no dissolved oxygen to sustain animals or plants, ocean anoxic zones are areas where only microbes suited to the environment can live.

"You don't get big fish," said UC Santa Barbara biogeochemist Morgan Raven. "You don't even get charismatic zooplankton." But although anoxic oceans may seem alien to organisms like ourselves that breathe oxygen, they're full of life, she said.

Winter is coming in the northern hemisphere and public health officials are asking how the seasonal shift will impact the spread of SARS-CoV-2, the virus that causes COVID-19?

What The Study Did: Researchers used publicly available data to examine all-cause excess mortality (the gap between observed and expected deaths) and COVID-19-related mortality during the early period of the pandemic among adults ages 25 to 44.

Authors: Jeremy Samuel Faust, M.D., M.S., of Brigham and Women's Hospital in Boston, is the corresponding author.

It's known that the primary cause of the mass extinction of dinosaurs, about 66 million years ago, was a meteorite impact. But the exact mechanisms that linked the meteorite impact to mass extinction remain unclear, though climactic changes are thought to have played a part.

Reston, Virginia--A pair of copper radionuclides that target the somatostatin receptor overexpressed in neuroendocrine tumors has proven successful in identifying tumors and improving survival. According to new research published in the December issue of The Journal of Nuclear Medicine, the imaging agent 64Cu-CuSarTate produced high-quality positron emission tomography (PET) images in a mouse model of neuroendocrine tumors, while its therapeutic counterpart, 67Cu-CuSarTate, was highly effective in reducing tumor volume and extending lifespan.

Spend time in any of the world's great forests and you'll start seeing the trees as immense pillars holding the heavens aloft while firmly anchored in the earth. It's as much fact as sentiment. Trees really do link the ground to the sky by exchanging energy and matter between the soil and the atmosphere. Researchers believe that understanding this connection could provide both a wealth of scientific insight into ecosystems and practical applications that address challenges such as water resource conservation and management.

A new special issue of the journal Innovation in Aging, titled "Race and Mental Health Among Older Adults: Within- and Between-Group Comparisons," is expressly devoted to much-needed research on aging and mental health within racial and ethnic minority populations (e.g., African Americans, Latinx, and Asian Americans, as well as subgroups within these larger pan-ethnic categories).

A recent study by a team of University of Cincinnati researchers shows that suicide planning, attempts and completions were already on the rise pre-COVID-19. Add a pandemic to a holiday season, when depression and suicide are typically higher among both adolescents and adults, and the last couple of weeks of 2020 may be a time to be on even higher alert.

According to health data, nearly 1.5 million Americans attempt suicide each year.
