The inside of a solid tumor has an environment distinct from the tissues around it. Rapid cell growth and proliferation outpaces blood-vessel development, leaving cells deep inside deprived of adequate oxygen and nutrients like glucose and amino acids.

Immunotherapies have revolutionized cancer treatment, offering hope to those whose malignancies have stubbornly survived other existing treatments. Yet solid tumor cancers are often resistant to these approaches.

People with hemophilia require regular infusions of clotting factor to prevent them from experiencing uncontrolled bleeding. But a significant fraction develop antibodies against the clotting factor, essentially experiencing an allergic reaction to the very treatment that can prolong their lives.

Applying to college can be a daunting task for any student. But for those who may be the first in their families to attend college, lack access to a trusted guidance counselor, or who worry about their family’s ability to pay for their education, the process can prove especially challenging.

Over the course of his three-decade-long career as a police K9 officer for Cheltenham Township, Bob Dougherty saw firsthand the benefits of having a well-trained police dog on the force.

Each spring for the last six years, the Philadelphia Science Festival has turned the city into one big classroom, with lively, entertaining, and hands-on lessons.

Invasive species are typically a bane to land managers, who often devote considerable time and expense to controlling or removing them. But a new study of coastal dunes at New Jersey’s Island Beach State Park finds that one invasive plant, Asiatic sand sedge (Carex kobomugi), which grows on beach dunes, has at least one redeeming quality.

The invasive species Carex kobomugi, or Asiatic sand sedge, was first found along the East Coast of the United States at New Jersey’s Island Beach State Park in 1929. The species is aggressive, outcompeting native vegetation and reducing local biodiversity. In many places, land managers have made great efforts to remove it.

Every time a hormone is released from a cell, every time a neurotransmitter leaps across a synapse to relay a message from one neuron to another, the cell must undergo exocytosis. This is the process responsible for transporting cellular contents via lipid-encapsulated vesicles to the cell surface membrane and then incorporating or secreting them through membrane fusion.
