Levels of alcohol consumption currently considered safe by some countries are linked with development of heart failure, according to research presented at Heart Failure 2022, a scientific congress of the European Society of Cardiology (ESC). “This study adds to the body of evidence that a more cautious approach to alcohol consumption is needed,” said study author Dr. Bethany Wong of St. Vincent's University Hospital, Dublin, Ireland. “To minimise the risk of alcohol causing harm to the heart, if you don’t drink, don’t start. If you do drink, limit your weekly consumption to less than one bottle of wine or less than three-and-a-half 500 ml cans of 4.5% beer.”
Tactile sensation is an incredibly important part of how humans perceive their reality. Haptics or devices that can produce extremely specific vibrations that can mimic the sensation of touch are a way to bring that third sense to life. However, as far as haptics have come, humans are incredibly particular about whether or not something feels “right,” and virtual textures don’t always hit the mark. Now, researchers at the USC Viterbi School of Engineering have developed a new method for computers to achieve that true texture — with the help of human beings. Called a preference-driven model, the framework uses our ability to distinguish between the details of certain textures as a tool in order to give these virtual counterparts a tune-up.

MIT researchers determined exactly what happens as crystal grains in metals form during an extreme deformation process, at the tiniest scales, down to a few nanometers across. The findings could lead to better, more consistent properties in metals, such as hardness and toughness.

An insightful cross-disciplinary team of University of Hawai‘i at Mānoa researchers, working for over a decade, published a study recently revealing that a key number of hours of darkness during the lunar cycle triggers mature “Hawaiian box jellyfish” (Alatina alata) to swim to leeward O‘ahu shores to spawn.

Texas A&M University researchers Dr. Sam Noynaert and Fred Dupriest recently presented results from a geothermal project that drastically reduced well-completion times and drill bit changeouts to an audience of mostly petroleum drillers. The Department of Energy (DOE) funded the project, which improves geothermal drilling practices with physics-based instruction and oil and gas techniques to lower the high cost of drilling geothermal wells. The time and equipment saved suggests the oil industry should take note.

Rather than being fueled by animosity for the other side — negative partisanship — a new study by researchers at the University of Pennsylvania finds that Americans are at least as motivated by the passion they have for their own party.
