The APL’s device can improve the daily lives of people with prosthetics

APL tests a new Modular Prosthetic Limb

The Modular Prosthetic Limb, developed by the Johns Hopkins University Applied Physics Lab (APL), has achieved new levels of operability thanks to a pioneering surgical procedure that allows the prosthetic to be directly and biomechanically attached to the amputee’s bone.

Researchers think life could be found on the outskirts of the Milky Way rather than in far-off galaxies.

Globular clusters may harbor interstellar life

The search for life outside of planet Earth has captivated science fiction writers, astronomers and society at large. However, the likelihood of finding such life is continually restricted by the limitations of technology and the sheer size of the universe.

Increased oceanic carbon dioxide levels can be deadly for fish.

Carbon dioxide threatens metabolism of fish

Everyone knows that climate change caused by carbon emissions is harmful to the environment. It causes rising sea levels, loss of biodiversity, reduced agricultural yields, constrained water supply, unpredictable weather patterns and more. New research from the University of New South Wales (UNSW) in Australia indicates that there might be yet another consequence to worry about: drunken fish.

 A newly discovered foam can propel bone growth, and may one day make casts unnecessary.

Injectable foam potentially builds new bone

Osteoporosis, a disease that results from an imbalance between bone resorption and bone growth, affects millions of Americans each year. Patients who suffer from this disease have weakened bones that fracture easily under impact, causing pain and problems in mobility. The patient usually does not realize that he or she has osteoporosis until he or she experiences the onset of constant back pain or a sudden fracture. To lower the risk of osteoporosis, doctors recommend exercise and a healthy diet, but there remains no treatment for osteoporosis-related injuries once the patient has the disease.

The meltwater surrounding glaciers has a large amount of nutrients that can support productivity.

Giant icebergs may play a key role in carbon cycle

A recent study done by the University of Sheffield’s Department of Geography discovered that water from melted giant icebergs supports extremely high levels of phytoplankton growth. This melted water contains iron and other nutrients and contributes to an activity known as carbon sequestration.


Researchers discover new antidepressant

Neuroscientists at Johns Hopkins Medical School have found that compound CGP3466B successfully delivers antidepressant effects to mice within mere hours. This compound, which has previously been shown to block cocaine craving in mice, rapidly delivers antidepressant effects when compared to most drugs, which can take weeks or even months.













HIV screenings could prevent new infections

Advancements in antiretroviral therapy (ART) in recent years have enabled human immunodeficiency virus (HIV) patients to benefit from fewer side effects as well as less stringent dosing schedules.
