Addiction care barriers fell due to COVID-19; experts see challenges in keeping them down

Recent COVID-19 policy shifts have made it possible for more people to access addiction care via telemedicine, specifically video chats and telephone calls. Key treatments like medications, psychotherapy, and peer group support can now be delivered remotely, but sustaining this approach will require continued changes.

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.

New drug reduces stroke damage in mice

Researchers at the University of Pittsburgh Brain Institute identified a novel drug that can protect the brain during and after a stroke. The study shows that injured neurons can remain viable if prevented from following biochemical pathways leading to cell death.
