New Zealand takes a stand on gun control

Ever since the shooting at Marjory Stoneman Douglas High School in Parkland, Fla. last year, gun control has been at the center of political debate. Though millions have marched for their lives, countless town halls have been held, and thousands more lives have been lost to gun violence in the U.S. since Feb. 14, 2018, minimal steps have been taken to address this issue.

Can sustainable investment fight climate change?

The Johns Hopkins Advanced Academic Programs and the National Academy of Sciences will host a Climate Change Symposium on May 3 called Changing by Degrees: Multidisciplinary Approaches to Climate Change. In light of this, students and faculty are identifying different methods of achieving sustainability.

Scientists develop a way to visualize black holes

Lately there has been a buzz in the field of astronomy. On April 10, a network of telescopes all across the globe was used to produce the first image of a supermassive black hole and its shadow located in the Messier 87 galaxy.

Mutations FAAH-OUT and FAAH can make someone unable to feel pain.

Two gene mutations can mute sensation of pain

From happily munching on chili peppers and feeling little to no pain during childbirth to accidentally ironing over her arms and being unaware of painful joint degeneration, Jo Cameron has lived a life of little pain, fear or anxiety.

Hopkins professor uses virtual reality goggles to study Mars

Kevin Lewis’ most recent project was to use gravity to “weigh a mountain” on Mars. In introductory physics classes, gravity is taught to be a constant equal to 9.8 meters per second. In reality, it varies from place to place depending on what is beneath you. If you stand on an iron ore, the pull of gravity will be a bit stronger. This quality makes gravity a useful geological tool to interrogate the subsurface of a planet. If gravity measurements do not match previously established expectations, then scientists can discern the density of the rocks underneath the surface.

Playing team sports as a kid was shown to reduce depressive symptoms.

Playing team sports could lower risk for depression

A new study from the Washington University in St. Louis revealed that involvement in sports is associated with changes in young children’s brains. The study was published last February in the journal Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

Scientists could “turn off” alcohol cravings

It’s nearing midnight and you’ve spent a productive day in Brody. You’ve had dinner, but you’re feeling a bit hungry after all the time working on that assignment for that class you have. All of a sudden, you get a craving — French fries. Cravings are a common occurrence, but have you ever wondered exactly what it is that drives them?


Humans may be able to sense magnetic fields

It’s a process that allows pigeons, honey bees and whales to navigate the world through the Earth’s magnetic field. Magnetoreception, a so-called sixth, geomagnetic sense, is found in bacteria, arthropods and multiple vertebrate species. It was thought to be completely beyond the perception of beings humans.

A study at the University of California, Santa Cruz showed that solitude could have benefits.

Study shows solitude can be good for mental health

In this day and age, depression amongst college students is a growing issue: According to the National Alliance on Mental Illness (NAMI), more than 10 percent of all college students have been diagnosed with depression. While many may believe that a telltale sign of depression can be social withdrawal and isolation, new studies conducted at the University of California, Santa Cruz (UC Santa Cruz) show that this may not always be the case; in fact, young adults who spend time alone can gain many benefits from this chosen solitude.

Scientists came up with a new genetic method to revert blindness.

Gene insertion helps blind mice regain eyesight

First evolved in animals 550 million years ago, the ability to see is essential to life. It helps animals navigate the world around them. Researchers at the University of California, Berkeley (UC Berkeley), may have found a way to reverse blindness caused by retinal degeneration and give people back the ability to fully experience the world.
