Estimation of excess deaths from COVID-19 in the US

Researchers analyzed weekly changes in US deaths due to COVID-19 and found a significant increase, indicating an estimated 1.8 million excess deaths between March 2020 and May 30, 2020. The study used data from the Centers for Medicare and Medicaid Services and the National Vital Statistics System.

Brain activity prior to an action contributes to our sense of control over what we do

Scientists identified specific brain regions linked to humans' sense of agency, finding that brain activity involved in planning and motor monitoring is crucial. By altering this network with transcranial magnetic stimulation, researchers were able to reduce participants' sense of control over their actions.

GPS isn't just for road trips anymore

Researchers found that GPS-guided tractors can reduce overlap and gaps in field coverage by up to 6% and 16%, respectively, leading to increased crop production and environmental benefits. This technology has the potential to be adopted by small farms, which currently lag behind larger producers in terms of technology adoption.

Is not helping a bad person good or bad?

A recent study challenges previous theoretical predictions on justified defection, a mechanism that ensures benefits are returned to cooperative individuals. Researchers found that people have a neutral attitude toward justified defection, unlike cooperation with a bad person, which is viewed as good.

Laser takes pictures of electrons in crystals

Researchers have developed a new laser-based microscope that can resolve the distribution of electrons in crystal lattices with unprecedented resolution. The technique, known as Light Picoscopy, uses powerful laser pulses to drive electrons into fast motion, allowing them to emit radiation that reveals their position within the crystal.

A simpler way to make sensory hearing cells

Researchers have successfully reprogrammed three types of mouse cells into induced hair cell-like cells, offering a potential solution for identifying causes and treatments of hearing loss. The new cells possess characteristics similar to naturally occurring hair cells and are vulnerable to an antibiotic known to cause hearing loss.

Treatments tested for invasive pest on allium crops

A Cornell University-led team of researchers found that traditional chemical insecticides work best against the invasive Allium leafminer on allium crops. Synthetic insecticides like dinotefuran and cyantraniliprole reduced damage by up to 89% and eradicated the insect in some cases.

How does our brain fold? Study reveals new genetic insights

A new pre-clinical study identified genes linked with the development of brain folds in the grey matter of the brain. The research found differences in genetic expression and neuron shape during the folding process, which can lead to cognitive deficits and neurological conditions such as autism and schizophrenia.

Growing numbers of alcohol related hospital admissions linked to local spending cuts

A study found that local authorities' spending cuts on alcohol services are associated with increased hospital admissions. The research, published in The British Journal of Psychiatry, analyzed data from 2012 to 2019 and found a link between reduced funding for specialist treatment and higher rates of alcohol-related hospitalizations.

The Lancet Infectious Diseases: Individual decisions to reduce movement -- even before state-wide stay-at-home policies were introduced -- likely helped slow the spread of COVID-19 in the USA

Before state-level stay-at-home policies were implemented, individuals in the US reduced their movement, which was strongly correlated with a decline in COVID-19 case growth. This suggests that social distancing played a crucial role in controlling the spread of COVID-19.

First exposed planetary core discovered

Scientists have discovered an exoplanet with an exposed core, similar in size to Neptune, orbiting a star about 730 light years away. The researchers believe the planet may be a gas giant that lost its atmosphere or failed to form one due to special circumstances.
