The expansion of wind energy in the German Bight and the Baltic Sea has accelerated enormously in recent years. The first systems went into operation in 2008. Today, wind turbines with an output of around 8,000 megawatts rotate in German waters, which corresponds to around eight nuclear power plants. But space is limited. For this reason, wind farms are sometimes built very close to one another. A team led by Dr. Naveed Akhtar from Helmholtz Zentrum Hereon has found that wind speeds at the downstream windfarm are significantly slowed down.
MADISON, Wis. -- For birds and other wildlife, winter is a time of resource scarcity. Extreme winter weather events such as a polar vortex can push some species to the edge of survival. Yet winter tends to get short shrift in climate change research, according to UW-Madison forest and wildlife ecology Professor Ben Zuckerberg.
The experimental drug TEMPOL may be a promising oral antiviral treatment for COVID-19, suggests a study of cell cultures by researchers at the National Institutes of Health. TEMPOL can limit SARS-CoV-2 infection by impairing the activity of a viral enzyme called RNA replicase. The work was led by researchers at NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). The study appears in Science.
Sickle cell disease (SCD) is the most common deadly genetic disorder, affecting more than 300,000 newborns worldwide each year. It leads to chronic pain, organ failure, and early death in patients. A team led by researchers at the Broad Institute of MIT and Harvard and St. Jude Children's Research Hospital has now demonstrated a base editing approach that efficiently corrects the mutation underlying SCD in patient blood stem cells and in mice. This gene editing treatment rescued the disease symptoms in animal models, enabling the long-lasting production of healthy blood cells.
Humans regularly exert a powerful influence on the survival and persistence of species, yet social-science information is used only sporadically in conservation decisions.
Researchers at Colorado State University and The Ohio State University have created an index depicting the mix of social values among people across all 50 states, providing data that can be useful for wildlife conservation policy and management.
NEW YORK CITY, June 2, 2021 -- New research from Memorial Sloan Kettering Cancer Center (MSK) medical oncologist Dean Bajorin, MD, and colleagues found that patients who received nivolumab (Opdivo®) after bladder cancer surgery reduced their overall risk for high-grade bladder cancer recurrence. This research was published in the New England Journal of Medicine.
SAN FRANCISCO, CA (June 3, 2021) -- Since arriving to the northern Atlantic Ocean less than 30 years ago, lionfish have quickly become one of the most widespread and voracious invasive species, negatively impacting marine ecosystems--particularly coral reefs--from the northeast coast of the United States to the Caribbean Islands.

Experts at the Alfred Wegener Institute have, for the first time, experimentally measured the release of iron from the fecal pellets of krill and salps under natural conditions and tested its bioavailability using a natural community of microalgae in the Southern Ocean. In comparison to the fecal pellets of krill, Antarctic phytoplankton can more easily take up the micronutrient iron from those produced by salps. Observations made over the past 20 years show that, as a result of climate change, Antarctic krill are increasingly being supplanted by salps in the Southern Ocean.
A facial expression or the sound of a voice can say a lot about a person's emotional state; and how much they reveal depends on the intensity of the feeling. But is it really true that the stronger an emotion, the more intelligible it is? An international research team comprised of scientists from the Max Planck Institute for Empirical Aesthetics, New York University, and the Max Planck NYU Center for Language, Music, and Emotion (CLaME) has now discovered a paradoxical relationship between the intensity of emotional expressions and how they are perceived.
Researchers from Bochum and Osnabrück have gained new insights into the structure of the Ras protein, which acts as a molecular switch for cell growth and is involved in the development of cancer. With the help of fluorescence markings, they have demonstrated that the protein is deposited in a pair at the cell membrane, and with the very structure that they predicted in theory back in 2012. The team from the Bochum Center for Protein Diagnostics (PRODI) hopes that these findings will open up a new approach for the development of cancer medications.
A team of researchers led by diabetes specialists and biomedical engineers at Washington University School of Medicine in St. Louis and Cornell University has demonstrated that, using a miniscule device, they can implant insulin-secreting cells into diabetic mice. Once implanted, the cells secrete insulin in response to blood sugar, reversing diabetes without requiring drugs to suppress the immune system.
The findings are published June 2 in the journal Science Translational Medicine.

Protein disguise could be new target for cancer immunotherapy
Researchers at the Francis Crick Institute have identified a protein that helps tumours evade the immune system and, in certain types of cancers, is linked to a poorer chance of survival. The protein could become a target for future cancer treatments.
Amsterdam, June 2, 2021 - On the eve of the 50th anniversary of the 1972 Stockholm conference that created the United Nations Environmental Programme, it is clear that the global environmental situation has only deteriorated.
Aging published "Cdkn1a transcript variant 2 is a marker of aging and cellular senescence" which reported that cellular senescence is a cell fate response characterized by a permanent cell cycle arrest driven primarily the by cell cycle inhibitor and tumor suppressor proteins p16Ink4a and p21Cip1/Waf1.
