Precipitation will be essential for plants to counteract global warming

A new study from Columbia University reveals that the balance between soil water and energy availability determines whether plant growth is limited by precipitation or temperature. This finding highlights the crucial role of precipitation in supporting plant photosynthesis, particularly during the late growing season.

Limitations on end-of-season photosynthesis

A study using satellite data and in-situ sensor observations found that the end date of plant photosynthesis is constrained by both temperature and water limits. As temperatures decrease, soil water demands increase to support continued vegetation growth, potentially leading to expansions of regions with limited photosynthesis.

New model finds countries should work together to control coronavirus, harmful species

A new model developed by Arizona State University researcher Adam Lampert suggests that countries should work together to control the spread of harmful species, including diseases like COVID-19. The model indicates that in some cases, a clear division of labor may be necessary, while in others collaboration is more effective.

Tailoring treatment for triple-negative breast cancer

A new study has identified a molecular pathway responsible for the progression and spread of triple-negative breast cancer (TNBC). By blocking the signaling pathway, researchers found that tumors grew and spread more slowly. The findings suggest that patients with low ELF5 protein levels should be given interferon-gamma signaling-block...

Future aerosol emission reductions will worsen atmospheric diffusion conditions in eastern China

Eastern China's air pollution has been a major concern, and new research suggests that future aerosol emission reductions could worsen atmospheric diffusion conditions conducive to extreme haze events. The study found that climate effects induced by aerosol reduction play a leading role in the anticyclone change in eastern China.

Hospitalizations down once power plants retired coal or installed better emission controls

After four Louisville, Kentucky, coal-fired power plants either retired coal or installed stricter emissions controls, local residents' asthma symptoms and related hospitalizations and ED visits dropped dramatically. The study found nearly 400 avoided hospitalizations and ED visits each year across Jefferson County.

Graphene heterostructures with black phosphorus, arsenic enable new infrared detectors

Researchers developed photodetectors using graphene layers with varying proportions of black phosphorus and arsenic, achieving lower dark currents and high photosensitivity. These sensors can enhance the performance of infrared telescopes and replace existing detectors, benefiting various scientific and technological applications.

Study finds remdesivir effective against a key enzyme of coronavirus that causes COVID-19

Scientists at the University of Alberta have shown that remdesivir is highly effective in stopping the replication mechanism of the coronavirus that causes COVID-19. The drug works by tricking the virus into incorporating itself as a building block, effectively preventing it from replicating.
