Researchers discovered that Zika virus can disrupt the growth of certain types of brain cells.

Zika virus can destroy neural progenitor cells

On March 19 the U.S. Center for Disease Control and Prevention (CDC) issued a Level 2 travel notice for those who plan to visit regions afflicted with Zika virus, encouraging travelers to practice enhanced precautions. These warnings about the Zika virus are growing alongside new evidence that causally links Zika virus to microcephaly, a condition that hinders brain development.

Roughly three million Americans are allergic to peanuts and tree nuts.

Peanut consumption may prevent allergy

A recent study published in the New England Journal of Medicine provides evidence that an early introduction of peanuts into the diets of infants will significantly reduce the risk of peanut allergy. More specifically, the study found that infants with a high risk of developing peanut allergy will be protected from having a peanut allergy at age five if they eat peanuts and peanut products frequently starting within the first 11 months of life.


Google’s AlphaGo defeats Go Master

Have you ever imagined a future where robots can play your favorite game with or against you? Now, imagine that you were a world champion at this game. If this were the case, you might think that no computer would be able to defeat you, which is exactly what the artificial intelligence (AI) community thought of the game Go.

The researchers who discovered this new, foldable material were inspired by the art of origami.

New material can fold into nearly any shape

A team of engineers recently found inspiration in the art of origami, creating a material that can fold itself into almost any imaginable shape. The material is able to change not only its shape, but its size and volume as well.

Previous seedlings planted in lunar soil simulant died after germination.

Researchers harvest crops from lunar soil

Recently, researchers at the Wageningen University and Research Center in the Netherlands found that they were able to grow 10 different crop species in soil samples designed to simulate Mars and the moon. The crops included common vegetables like tomatoes, peas, rye, garden rocket (arugula), radishes and garden cress.

Quantum dots glow different colors based on their size and shape.

Quantum dots shed light on viral infections

Within the past decade, research on quantum dots, particularly in the biomedical research field, has developed rapidly. New research focuses on combining the fields of nanomaterials and biomolecules to get nanoparticles to recognize and bind with biomolecular targets. Once combined with biomolecules, quantum dots can be used for specific cell labeling and imaging.


New material could serve as robotic skin

Technology does change quickly, sometimes in leaps and bounds, but in this well-connected age, you don’t have to be prescient to predict the advances that are pushing us into a new reality resembling science fiction.


Bacteria in your body can intercept viral RNA

A team of scientists from the University of Texas at Austin, the Stanford University School of Medicine and two other research institutions has unearthed bacteria’s ability to recognize and intercept viruses, utilizing a mechanism involving RNA.


A new discovery can help decimate tumors

Researchers have developed a means to specifically identify and target tumor cells using specialized immune cells called T-cells, as well as antigens, that flag the earliest mutations of tumor cells.

Coloring can be an enjoyable and relaxing activity for students who are stressed.

Coloring can be therapeutic for students

The next time you see a child coloring, take a moment and observe him or her. It may seem like this child is consumed with the experience and not showing any signs of stress or despair. Perhaps the child is even showing outward signs of enjoyment and relaxation. A recent movement suggests that coloring might have similar effects on adults as well.

 Computers can tell how engaged you are by reading and quantifying your body language.

New computers can gauge users’ boredom

Imagine that you have just gotten home after a long day of classes. It’s a Tuesday afternoon and you decide to plop down on your couch, log on to Facebook, browse the first six pages of Reddit and then open up some lecture notes. However, you soon wake up and realize you’ve been asleep for three hours. All of a sudden you remember that you have a midterm tomorrow and a paper due on Friday. This situation may soon be a thing of the past because new research could lead to the development of a computer screen that keeps you awake when you need to be.

Monkeys with BMIs were able to navigate a robotic wheelchair.

Monkeys control wheelchairs with thought

A recently developed brain-machine interface (BMI) allows monkeys to control and navigate a robotic wheelchair using only their thoughts. This project was conducted by a group of neuroscientists at Duke Health and published in the March 3 issue of Scientific Reports. It focuses specifically on hundreds of neurons in two regions of the brain that are involved in movement and sensation.


Scientists at Massachusetts Institute of Technology (MIT) have created the thinnest existing solar cell, which is light enough to sit on top of a soap bubble without popping it.

Scientists develop thinnest solar cells

Solar or photovoltaic cells convert the sun’s light to electricity. They are currently used in many different contexts from large-scale operations such as powering water treatment plants and lighting systems to smaller uses like powering watches and calculators. The industry standard involves manufacturing the cells using a silicon semiconductor in a metal frame covered by a protective covering of silicon rubber or butyryl plastic. High temperatures and powerful solvents are required in order to bind all of the components of the cell together. After they are constructed the solar cells must be covered in protective plastic or glass before they can be distributed and installed.


Repurposed skin cells can help treat cancer

A recent breakthrough from researchers at the University of North Carolina at Chapel Hill has shed more light on a potential mechanism of treating cancer. Cancer in its most basic sense is a disease that involves abnormal and uncontrollable cell growth, but its complex biology makes treatment difficult. This challenge has spurred thousands of scientists to explore the mechanisms of cancer and work on developing more effective cures for the disease.

Paroxetine can improve cognitive function in patients with HIV.

Paroxetine improves cognitive function

Researchers at the Johns Hopkins University School of Medicine have discovered that paroxetine, an antidepressant, is able to improve cognitive function in patients suffering from HIV-associated cognitive impairment.

 Researchers modified the gene expression of the gut cells of fruit flies to change the cells’ sex.

Organs may also have sexual identities

Currently, it is commonly thought that the cells in the non-reproductive organs of both sexes are relatively similar — and that any difference in lung or heart or liver function is due solely to the different hormones that circulate in males and females.

A recent study found that particulate air pollution is linked to obesity and other diseases.

Air pollution leads to weight gain in rats

China is second only to the U.S. in obesity rankings, with an overweight population that has reached 300 million people in the last three decades. Although the majority of obese individuals are adults, children and adolescents are also affected, and health risks caused by obesity include conditions such as diabetes, cardiovascular disease and various types of cancer.
