Black Hole Burps: Particle Absorption and Emission in Supermassive Black Holes

Black holes are fascinating objects to study because we can use them to learn more about about astronomy, cosmology, and gravity. Black holes are super-massive and super-dense objects in the universe. Because of these properties, they produce strong gravitational and electromagnetic forces that suck nearby objects in. After ‘eating’ all this extraneous matter, the black hole has energy to spare and then ‘burps’, emitting high-energy … Continue reading Black Hole Burps: Particle Absorption and Emission in Supermassive Black Holes

Arctic Apples: A fresh new take on genetic engineering

by Allison Baker figures by Lillian Horin The Arctic apple is the juiciest newcomer to produce aisles. It has the special ability to resist browning after being cut (Figure 1), which protects its flavor and nutritional value. Browning also contributes to food waste by causing unappealing bruising on perfectly edible apples. Food waste, especially for fruits and vegetables, is a major problem worldwide; nearly half … Continue reading Arctic Apples: A fresh new take on genetic engineering

Regeneration: What the axolotl can teach us about regrowing human limbs

by Garrett Dunlap figures by Rebecca Senft Limb loss affects nearly 2 million people in the United States alone. While many instances are related to traumatic events like car accidents, the majority of limb loss cases are caused by diseases that affect the body’s blood vessels. One such disease is diabetes, in which gradual declines in blood flow to a patient’s lower extremities can eventually … Continue reading Regeneration: What the axolotl can teach us about regrowing human limbs

Fighting the Opioid Addiction Crisis: Can scientists cure it?

by Mary May figures by Neal Akatsuka An estimated 59,000 to 65,000 Americans died due to drug overdoses last year, which is more than the number of deaths from HIV/AIDS at the peak of the epidemic in 1995 and more than the total number of American deaths in the Vietnam War. The over-prescription of pain-relieving opioid drugs like morphine and oxycodone has created another epidemic … Continue reading Fighting the Opioid Addiction Crisis: Can scientists cure it?

The Science behind Keeping your Resolutions

We all want to start the year right, but making a change is hard. Luckily, behavioral scientists have found ways to form new, healthy habits, so that maintaining a resolution is easier than ever. Is it better to start slowly or with a bang? Two economists offered 3 groups of 40 people monetary incentives to exercise for a month. The groups were characterized by how … Continue reading The Science behind Keeping your Resolutions

Viruses, not all are bad for you

When you think of viruses, the yearly flu or even the Ebola or Swine flu outbreaks may come to mind. However, not all viruses cause disease – some even provide cures! Adeno-associated virus (AAV) can infect humans, but is not known to cause disease. In other words, this virus is good at getting its genetic information (genes) into human cells. What if its genes were … Continue reading Viruses, not all are bad for you
