New models may upend the origins of ocean animals
2dA study offers new context for a pivotal step in the evolution of life on Earth: the dramatic proliferation of animal life, hundreds of millions of years ago, in the ancient sea. The prevailing scientific theory has been that ancient waters were filled with nutrient-rich particulate matter, giving the oceans a soup-like consistency. In that scenario, early animal life—living on the seafloor and s

2dResearchers can now rapidly isolate and chemically characterize individual organelles within cells. The new technique tests the limits of analytical chemistry and rapidly reveals the chemical composition of organelles that control biological growth, development and disease.
Radiation makes heart cells young again to treat arrhythmia
•
2dRadiation Therapy Younger
Radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure, new research suggests. In that invasive procedure—catheter ablation—a catheter is threaded into the heart, and the tissue that triggers the life-threatening irregular heart rhythm—called
OVERBLIK Får vi flokimmunitet, og skal du have tredje stik? Sådan går det med vaccinerne

When will the COVID pandemic end?
2dThe worst of the pandemic may finally be over, according to new modeling results from a consortium of researchers advising the US Centers for Disease Control and Prevention. The team's COVID-19 Scenario Modeling Hub , which is co-coordinated by researchers at Penn State, projects that COVID-19 cases will decrease across the United States, barring the emergence of any new variants or major changes
Delayed global warming could reduce human exposure to cyclones
2dNature, Published online: 30 September 2021; doi:10.1038/d41586-021-02659-4 Rising temperatures are expected to increase the number of people exposed to tropical cyclones, but timing might prove crucial to the success of mitigation strategies.
New rules will make UK gene-edited crop research easier
2dNature, Published online: 30 September 2021; doi:10.1038/d41586-021-01572-0 The government's decision to ease requirements will lower the cost of field trials, but does not yet address the path to market.
Hi all! This research based video discusses what a sex addiction is- the controversy of the term, biological and psychological theories behind it. Hope you enjoy, references in the description 🙂

'Planet confusion' could slow Earth-like exoplanet exploration
2dA new study finds that next-generation telescopes used to see exoplanets could confuse Earth-like planets with other types of planets in the same solar system.

Fewer people used city parks during first COVID-19 summer
2dContrary to anecdotal reports of a spike in new users during the COVID-19 pandemic, fewer people used outdoor parks and trails in urban areas of North Carolina during two summer months of 2020, according to a new study. The study also found that that the drop-off in urban park access was more likely to affect minorities and people from lower-income backgrounds. "Visitation declined in urban and c
This Noise Cancelling App Uses AI To Eliminate Unwanted Sounds From Calls and Meetings
2dMore people are working from home now than ever, which means that more of us have become painfully aware just how noisy everybody's homes can be. Online work meetings can be convenient and safer than meeting in an office conference room but not anywhere near as quiet, unless of course the participants in that meeting are using Krisp , an incredible (and free to use) noise cancelling app that uses
Scientists create material that can both move and block heat
2dScientists have invented a new way to funnel heat around at the microscopic level: a thermal insulator made using an innovative technique. They stack ultra-thin layers of crystalline sheets on top of each other, but rotate each layer slightly, creating a material with atoms that are aligned in one direction but not in the other. The result is a material that is extremely good at both containing he
