Study finds 1.7 million New Yorkers have been infected with SARS-Cov-2 and virus was in NYC earlier than reported

A retrospective surveillance study of over 10,000 plasma samples found that more than 1.7 million New Yorkers have been infected with SARS-CoV-2, indicating the virus was present in the city before the first confirmed case. The infection fatality rate is close to 1 percent, ten times deadlier than the flu.

How to fix the movement for fossil fuel divestment

The fossil fuel divestment movement has failed to reverse the trend of capital flowing into carbon-intensive industries due to its binary distinction between fossil and non-fossil companies. A more nuanced campaign focusing on low-carbon (re-)investment, modeled after credit ratings for climate change, is proposed as a solution.

Earwax sampling could measure stress hormone

Researchers at UCL and King's College London developed a novel earwax sampling technique to measure cortisol levels, which appear more stable than traditional methods. The new device can be used at home without clinical supervision, facilitating medical check-ups while maintaining social distancing.

Supersonic winds, rocky rains forecasted on lava planet

The study predicts extreme weather conditions on K2-141b, including supersonic winds and rocky rains, which can be detected from hundreds of light years away with next-generation telescopes. The team also found that two-thirds of the exoplanet faces perpetual daylight, leading to frigid temperatures on the night side.

Buffalo fly faces Dengue nemesis

Researchers are exploring three approaches using the Wolbachia bacterium to control the buffalo fly population and prevent its spread southwards. The methods include artificially infecting adult flies or pupae, releasing sterile males into overwintering areas, and blocking transmission of nematodes closely related to Stephanofilaria.

Your favorite music can send your brain into a pleasure overload

Researchers used EEG to study how music affects the brain's reward system, finding increased activity in regions involved in emotional processing, movement control, and auditory processing. Chills induced by favorite songs release dopamine, triggering a physiological response that indicates greater cortical connectivity.

Association between African American race, clinical outcomes in men treated for low-risk prostate cancer with active surveillance

African American men with low-risk prostate cancer treated under active surveillance have a higher risk of disease progression and mortality compared to non-African American patients. The study's findings suggest that racial disparities exist in the clinical outcomes of prostate cancer treatment with active surveillance.

Model of multicellular evolution overturns classic theory

A new study overturns the classic theory that single-celled organisms can only evolve to become multicellular life forms if doing so increases their overall productivity. The model suggests that cell specialization can be favored even if it reduces group productivity, contradicting the prevailing view.

Oncotarget: Heterogeneity of CEACAM5 in breast cancer

Researchers assessed CEACAM5 expression in breast cancer subtypes using immunohistochemistry, finding a high correlation between primary tumor and lymph node status. Expression of CEACAM5 also predicted different clinical outcomes depending on molecular subtypes, suggesting its potential role as a clinically relevant marker.
