Study warns synthetic cannabis alternative ‘spice’ has worse withdrawals

The synthetic drug known as spice ("K2") is designed to mimic the effects of cannabis; it was presented as a legal alternative to the largely illegal substance, but things have changed. Many studies have found that spice often has many different and more dangerous effects compared to marijuana, which is now legal in many states. The latest study finds that it is also harder to kick a spice habit.

It turns out gophers glow when you shine a UV light on them

It turns out gophers glow when you shine a UV light on them

The rodent popularly known as a pocket gopher can glow, it turns out, but only if you shine a UV light on it. The discovery was detailed in a new study from the University of Georgia, which reports that these underground-dwelling rodents are, in fact, biofluorescent. How was the discovery made? Some curious researchers shined a UV light on various rodents to see which of them lit up.

Archaeologists discover ancient bone tools for leathermaking

Archaeologists discover ancient bone tools for leathermaking

Archaeologists have made an interesting discovery that sheds light on what types of clothing ancient humans wore. According to the researchers, between 90,000 and 120,000 years ago, humans commonly wore skins and furs from animals like sand foxes, golden jackals, and wildcats. The study's authors determined the types of skins and furs worn by ancient humans based on evidence gathered from 62 different bone tools found in a cave in Morocco.

Microneedle array delivers medication directly to a wound

Microneedle array delivers medication directly to a wound

An engineer from Purdue University has developed a new method of treating wounds for people who suffer from diabetic foot ulcers. Rahim Rahimi is an assistant professor in the School of Materials Engineering and has created a microneedle array on a flexible polymer composite. The array is designed specifically to treat chronic non-healing wounds by penetrating the physiochemical bacterial biofilm on the wound's surface, allowing it to be oxygenated and to deliver bactericidal treatments.

COVID-19 vaccine study has good news for people with multiple sclerosis

COVID-19 vaccine study has good news for people with multiple sclerosis

Researchers with the University of Pennsylvania have good news for people who have multiple sclerosis and are taking anti-CD20 treatment -- though their antibody response triggered by the vaccine may be low, their bodies are still able to produce "robust T-cell responses" against the SARS-CoV-2 virus. As a result, the researchers say MS patients receiving the anti-CD20 treatment should still get the COVID-19 vaccines.

Study warns COVID-19 is getting better at spreading through the air

Study warns COVID-19 is getting better at spreading through the air

Newly published research reveals that COVID-19 is getting better at spreading through the air as it evolves, putting more people at risk of contracting the virus. The study involved the Alpha, not Delta, variant due to its dominance when the research was conducted, but the scientists note that the now-dominant Delta variant is even more contagious than the Alpha variant they studied.

Stem cell breakthrough treats dog hip problems by regrowing cartilage

Stem cell breakthrough treats dog hip problems by regrowing cartilage

As a dog ages, it may develop arthritis -- and, depending on the breed, it may experience particularly severe issues with its hip joints, potentially requiring a resurfacing implant. In the future, this process may be far less invasive while offering better results than conventional treatments. Key to the newly detailed process are stem cells.

Researchers create strangely shaped liquids using electric fields

Researchers create strangely shaped liquids using electric fields

We've all seen drops of water and know that they tend to take on the same basic shape no matter what liquid the drop is made from. Researchers from Aalto University in Finland wanted to disrupt what's known as thermodynamic equilibrium to explore what happens and to determine if they could control what happened when equilibrium was disrupted.

Mysterious results in an experiment may be due to dark energy

Mysterious results in an experiment may be due to dark energy

One of the most mysterious subjects that scientists around the world are studying is called dark energy. Scientists believe dark energy is the mysterious force that leads to acceleration in the universe. A team of researchers from the University of Cambridge has published a study that suggests unexplained results obtained from an experiment conducted in Italy called XENON1T could have been caused by dark energy.

Organic molecules may be more widely distributed in the galaxy than previously believed

Organic molecules may be more widely distributed in the galaxy than previously believed

Researchers from the University of Leeds have been studying the galaxy, looking for organic molecules necessary to form life as we know it. The lead researcher for the study was Dr. John Ilee. He says that the basic chemical conditions that resulted in life on our planet may be more widely distributed across the galaxy than previously believed. During the study, scientists discovered fingerprints in light emitted from material surrounding young stars indicating there are reservoirs of large organic molecules around those stars necessary to form life.

NASA study warns smart car features may increase drowsy driving risk

NASA study warns smart car features may increase drowsy driving risk

NASA is looking into the factors behind fatigued driving and how new automation technologies may both help -- and exacerbate -- the problem. Drowsy driving is responsible for many vehicular accidents and deaths every year, according to the NHTSA, but partially automated vehicles equipped with smart features may make this issue worse, not better.

Homemade face masks work, but it depends on how they’re made

Homemade face masks work, but it depends on how they’re made

Though N95 and surgical face masks are the best options when it comes to reducing the spread of droplets, homemade face masks are also effective...assuming they're made correctly, according to researchers with the India Institute of Science. Homemade face masks may be used because they're more economical than buying boxes of surgical masks, or they may be used when commercial masks are in short supply.
