Unequal neutron-star mergers create unique "bang" in simulations

A team of researchers found that unequal neutron-star mergers can create an electromagnetic signal, which could be detected using gravitational-wave detectors like LIGO. The simulations revealed that the larger star tears apart its partner, creating a slower merger and allowing an 'electromagnetic bang' to escape.

Researchers identify evolutionary origins of SARS-CoV-2

A team of international scientists reconstructed the evolutionary history of SARS-CoV-2 and found that the lineage has been circulating in bats for decades. The study suggests that preventing future pandemics requires better sampling within wild bats and real-time human disease surveillance systems.

Enhanced water repellent surfaces discovered in nature

Researchers at Penn State have discovered a previously unidentified nanostructure on insect surfaces that can be used to engineer stronger, more resilient water repellent coatings. These high-solid fraction textures may imbue additional water repelling benefits and could be applied to personal protective equipment (PPE) to better resis...

Over $10 million awarded to Penn State for energy center

The US Department of Energy has awarded Penn State over $10 million to develop new ferroelectric memory materials that can be stacked in the third dimension above processor chips. This breakthrough technology aims to mitigate the von Neumann bottleneck, allowing for seamless communication between memory and computation.

What determines a warbler's colors?

A new study has narrowed down the region of the genome that drives the black color in warblers by studying hybrid offspring. The hybrids have a mix of coloration from the parent species, allowing researchers to identify which regions of the genome are associated with which color patterns.

About nine family members to suffer grief from every COVID-19 fatality

A study by Penn State researchers found that every COVID-19 death will impact around nine surviving close family members, including grandparents, parents, siblings, spouses, and children. The multiplier effect may help raise awareness about the disease's ripple effects and inform policies on family leave and paid leave.

New insights into van der Waals materials found

The study observed a rare phenomenon known as the dynamic breaking of Friedel's Law in layered van der Waals materials, where the pairs of Bragg peaks show opposite oscillating patterns. This unique behavior is attributed to the lattice structure of the material and its effect on electron diffraction.

Knowledge of severe storm patterns may improve tornado warnings

Researchers found a statistically significant difference in storm structure between those producing tornadoes and non-tornadic supercells, which could lead to more accurate warnings. The study suggests using polarimetric radar data to identify the orientation of raindrop shapes, potentially improving tornado warning times.

Sunnier but riskier

Research confirms that breeding areas with more open canopies do provide opportunities for timber rattlesnakes to reach required body temperatures, but also increase risk of hawks and bobcats. Forest managers should balance canopy cover and predation risk during future conservation efforts.

Keeping water and energy secure

Researchers investigate vulnerability of smart city water and energy systems to cyber attacks, which can cause blackouts and damage. The study aims to develop detection methodologies to counteract such criminal acts using mathematical attack models and big data analytics-based methods.

Larger streams are critical for wild brook trout conservation

A genetic analysis of brook trout in Loyalsock Creek drainage reveals that fish are moving between tributaries, using the mainstem as a seasonal corridor. This finding contradicts previous research and suggests that conservation efforts should focus on larger streams and rivers to protect critical movement corridors.
