Nicotinamide riboside supplements may lower blood pressure in elderly.

Low-fat and low-carb diets equally beneficial

Obesity is a leading issue in American culture. More than one in three adults in the United States are considered obese, according to the National Institute of Diabetes and Digestive and Kidney Diseases. Low-fat diets and low-carbohydrate diets are two popular strategies for weight loss.

Nicotinamide riboside supplements may lower blood pressure in the elderly.

Dietary supplement may delay physiological aging

A study conducted by researchers at the University of Colorado Boulder (CU Boulder) indicates that nicotinamide riboside (NR), a dietary supplement, may provide the same health benefits as restricting calories. The findings were reported in a paper published on March 29 in Nature Communications. 


Prosthetic implant in brain improves memory

Prosthetics is a focus area in biomedical engineering that has been constantly expanding. Recently, scientists came up with a novel way of incorporating a person’s prosthetic memory system into regulatory brain processes such as encoding and retrieving memories.


Social media created our political climate

Perhaps, though, what is most unique about the political environment we find ourselves in now, is the role the internet and social media play in shaping it. The internet has connected us in ways never before imaginable, but with that newfound connection comes new challenges. 


Researchers discover new organ: the interstitium

A scientific discovery hidden in plain sight is a rare occurrence in the research world. Yet, endoscopists at Beth Israel Medical Center, David Carr-Locke and Petros Benias, and New York University Professor Neil Theise have accomplished just that with their discovery of a new organ, the interstitium. 


The use of iron lungs as treatment for polio

In 1928, the first patient to use the iron lung was an eight-year-old girl, suffering from respiratory paralysis as a result of poliomyelitis, or polio. Though she later died from cardiac failure, the device, an artificial respirator, had kept her breathing — and alive — for over five days. 


The origin of life may be colder than we thought

The origin of life is perhaps the most tantalizing question in science. Was it catalyzed by a high-energy lightning strike to the right amalgam of molecules? Did it travel from deep space on an asteroid, only landing on our planet by an improbable collision?

The newly engineered Soft Robitic Fish (SoFi) has many motor advances. 

Researchers create robot fish to study marine life

Researchers from the Computer Science and Artificial Intelligence Lab at the Massachusetts Institute of Technology (MIT) conceptualized a biomimetic fish that could swim alongside marine life. The robotic fish is classified as an autonomous underwater vehicle (AUV) capable of observation, motion and communication.

The fetus or newborn Ata skeleton was disovered in the Atacama Desert in Chile in 2003. 

Child fossil shows molecular complexity of bone disease

In 2003, a skeleton was discovered in the Atacama Desert in Chile. This skeleton, which has since been named “Ata” was tiny, about six inches long, with strange and dramatic deformities: a long skull pointed at the top, deep angular eye sockets and fewer ribs than normal. Some observers thought it looked alien.

Researchers used soy plants as inspiration for tissue regeneration ideas.

New methods for tissue regeneration discovered

Researchers at the Harvard School of Engineering and Applied Sciences have recently found two new techniques for tissue regeneration. One technique draws inspiration from naturally occurring proteins found in fetuses, while the other draws inspiration from soy plants.

The Quest to find the “Female Orgasm”

A recent study conducted by a team of world-class psychologists and gynecologists at the School of Medicine have determined that previous research severely overestimated the prevalence of the female orgasm.


Genetics lab creates human/blue jay hybrid to increase school spirit

Plans for a new blue jay/human hybrid created by the University’s Recombinant Genetics Lab (RGL) were recently leaked online. The hybrid is intended to replace Jay the Blue Jay as the University’s official mascot. According to the leaked documents, it will be unveiled at this season’s homecoming lacrosse game and is projected to increase school spirit by 23 percent. The hybrid does not yet have a name and is referred to in the documents only as “Blue Jay Man.”

Researchers recently developed a drug that can protect the cochlear cell line.

New drug could stop human hearing loss

According to the World Health Organization, over 446 million people suffer from hearing loss worldwide. Cisplatin is a widely used chemotherapeutic agent used to treat patients with cancer, but one of the major side effects is irreversible hearing loss in up to 70 percent of patients who take the drug.

The cold weather that extends to late March is actually a warning sign of global warming in the Arctic region.

Arctic warming contributed to our colder winter

For the millions who live in the eastern half of the country, this winter has been especially extreme. While multiple blizzards over the past few months have led some to claim that these frequent storms provide counterevidence for global warming, ironically, new research has shown otherwise. A new study from Rutgers University has linked this extreme winter in the U.S. with warm conditions in the Arctic.

Early childhood experiences can affect DNA state in the brain.

Brain DNA can be altered by childhood experiences

There is often the notion that DNA is a set of permanently stable biological sequences, but in reality, the genetic code is far more complex than most people think. DNA is under the constant influence of environmental factors and randomly arising mutations. Most recently, researchers at the Salk Institute discovered that DNA can also be directly modified by early life experiences.

Hörst’s research sought to understand the effect haze has on a planet’s habitat conditions.

Hopkins scientist observes exoplanet gas conditions

In spring 2019, the James Webb Space Telescope will be launched into space from French Guiana to seek other sources of life outside the solar system. A group of scientists lead by Sarah Hörst, assistant professor of Earth and Planetary Sciences at Hopkins, has recently published its results on haze formation in simulated environments.
