High-risk drinkers who substantially reduce their alcohol use can lower their risk of cardiovascular disease (CVD) despite not completely abstaining, according to study findings published in Alcoholism: Clinical and Experimental Research. CVD encompasses a range of conditions involving the heart or blood vessels, and is the leading cause of death in the US. It is also one of many negative health outcomes associated with heavy drinking and alcohol use disorder (AUD). Reductions in drinking can be defined using World Health Organization (WHO) ‘risk drinking levels’, which classify drinkers into ‘very high’, ‘high’, ‘moderate’ and ‘low’ risk categories based on their average daily alcohol consumption. Previous research has shown that a reduction of two or more levels (for example, from ‘very high’ to ‘moderate’) can lower the risk of multiple health issues, but did not assess the impact on CVD specifically. The latest study has examined associations between reductions in WHO risk drinking

Glass- and carbon- fiber reinforced composites, whose use in aerospace and other high-performance applications is soaring. Components made of these materials are often 3D printed. Their strength and flexibility depends on how each layer of fibers is deposited by the printer head, whose layer-by-layer orientation is determined by toolpath instricutions in a component's CAD file. A team of NYU Tandon researchers showed that that 3D printing toolpaths are easy to reproduce — and therefore steal — with machine learning. They demonstrated a method of reverse engineering of a 3D-printed glass fiber reinforced polymer filament that, when 3D-printed, has a dimensional accuracy within one-third of 1% of the original part.
At a time when the national conversation is focused on narrowing the gap of racial equity, two of Cleveland’s anchor institutions have been awarded grant funding that will help them turn words into action.

Research out today in the journal Cell shows that a specific change in the SARS-CoV-2 coronavirus virus genome, previously associated with increased viral transmission and the spread of COVID-19, is more infectious in cell culture.
Two variants of the novel coronavirus (SARS-CoV-2), called G614 and D614, were circulating in mid-March. A new study shows that the G version of the virus has come to dominate cases around the world. They report that this mutation does not make the virus more deadly, but it does help the virus copy itself, resulting in a higher viral load, or "titer," in patients.
A new research study provides possible explanations for COVID-19 patients who present with extremely low, otherwise life-threatening levels of oxygen, but no signs of dyspnea (difficulty breathing). This new understanding of the condition, known as silent hypoxemia or “happy hypoxia,” could prevent unnecessary intubation and ventilation in patients during the current and expected second wave of coronavirus.
Teleportation is most commonly the stuff of science fiction and, for many, would conjure up the immortal phrase "Beam me up Scotty".
