Ben-Gurion U. studies show promise using drones to elicit emotional responses
"There is a lack of research on how drones are perceived and understood by humans, which is vastly different than ground robots." says Prof. Jessica Cauchard together with Viviane Herdel of Ben-Gurion University of the Negev Magic Lab, in the Department of Industrial Engineering & Management. "For the first time, we showed that people can recognize different emotions and discriminate between different emotion intensities."

Researchers explore ways to detect 'deep fakes' in geography
It may only be a matter of time until the growing problem of "deep fakes" converges with geographical information science (GIS). A research team including faculty at Binghamton University are doing what they can to get ahead of the problem.

Aortic condition more deadly in women than in men
Women who experience acute aortic dissection--a spontaneous and catastrophic tear in one of the body's main arteries--not only are older and have more advanced disease than men when they seek medical care, but they also are more likely to die.

A 'jolt' for ocean carbon sequestration
Global oceans absorb about 25% of the carbon dioxide released into the atmosphere when fossil fuels are burned. Electricity-eating bacteria known as photoferrotrophs could provide a boost to this essential process, according to new research from Washington University in St. Louis.

Magnesium ions injected directly into compromised bone accelerate bone regeneration
Orthopedic patients are typically given oral magnesium (Mg) supplements to aid bone regeneration. In this study, researchers tried replacing that supplement with an injection -- directly into the impacted bone -- of custom-made, polymer microspheres that control the release of magnesium ions. They found that the injections accelerated bone formation in vivo.

Converting scar tissue to heart muscle after a heart attack
Researchers from the University of Tsukuba showed that cardiac scar tissue (fibroblasts) can be directly reprogrammed to heart muscle cells (cardiomyocytes) in mice. By treating mice post-heart attack with a virus carrying cardiac transcription factors, they found that new cardiomyocytes were formed by fibroblasts converting into cardiomyocytes as opposed to fibroblasts fusing with existing cardiomyocytes. This study demonstrates the potential of direct reprograming as a strategy for cardiac regeneration after myocardial infarction.

Newly identified atmospheric circulation enhances heatwaves and wildfires around the Arctic
Scientists have uncovered a summertime climate pattern in and around the Arctic that could drive co-occurrences of European heatwaves and large-scale wildfires with air pollution over Siberia and subpolar North America.

How an elephant's trunk manipulates air to eat and drink
New research from Georgia Tech finds that elephants dilate their nostrils in order to create more space in their trunks, allowing them to store up to nine liters of water. They can also suck up three liters per second -- a speed 50 times faster than a human sneeze. The findings could inspire different ways to building robots that manipulate air to move or hold things.

Analysis reveals global 'hot spots' where new coronaviruses may emerge
Global land-use changes -- including forest fragmentation, agricultural expansion and concentrated livestock production -- are creating "hot spots" favorable for bats that carry coronaviruses and where conditions are ripe for the diseases to jump from bats to humans, finds an analysis published this week by researchers at the University of California, Berkeley, the Politecnico di Milano (Polytechnic University of Milan) and Massey University of New Zealand.

Time-dependent viral interference between influenza virus and coronavirus in the infection of differ
A new study carried out in pig cells suggests previous infection with swine influenza virus (SIV) can protect against the development of porcine respiratory coronavirus (PRCoV) if there is a zero- or three-day interval between infections.

Forged books of seventeenth-century music discovered in Venetian library
In 1916 and 1917, a musician and book dealer named Giovanni Concina sold three ornately decorated seventeenth-century songbooks to a library in Venice, Italy. Now, more than 100 years later, a musicologist at Penn State has discovered that the manuscripts are fakes, meticulously crafted to appear old but actually fabricated just prior to their sale to the library. The manuscripts are rare among music forgeries in that the songs are authentic, but the books are counterfeit.

New method to improve durability of nano-electronic components, further semiconductor manufacturing
Researchers at the University of South Florida have developed a novel approach to mitigating electromigration in nanoscale electronic interconnects that are ubiquitous in state-of-the-art integrated circuits. This was achieved by coating copper metal interconnects with hexagonal boron nitride (hBN), an atomically-thin insulating two-dimensional (2D) material that shares a similar structure as the "wonder material" graphene.

New evidence may change timeline for when people first arrived in North America
An unexpected discovery by an Iowa State University researcher suggests that the first humans may have arrived in North America more than 30,000 years ago - nearly 20,000 years earlier than originally thought.

Scientists develop novel therapy for crimean-congo hemorrhagic fever virus
Army scientists working as part of an international consortium have developed and tested an antibody-based therapy to treat Crimean-Congo hemorrhagic fever virus (CCHFV), which is carried by ticks and kills up to 60 percent of those infected. Their results are published online today in the journal Cell.

Sloan Kettering Institute scientists learn what fuels the 'natural killers' of the immune system
Sloan Kettering Institute scientists are understanding more about natural killer (NK) cells, which are your allies when it comes to fighting infections and cancer. "There's a lot of interest right now in NK cells as a potential target of immunotherapy."
