Summary
A woman died from a direct lightning strike, which caused shrapnel injuries. Lightning hitting concrete created fragments, leading to this rare injury documented for the first time.
Area of Science:
- Forensic Pathology
- Environmental Medicine
Background:
- Lightning strikes are a significant cause of weather-related mortality globally.
- Direct strike injuries are the most common mechanism of lightning-related death.
- Secondary effects, such as ground current and side flash, can also cause injury.
Observation:
- A 48-year-old woman in Pretoria, South Africa, experienced a fatal direct lightning strike.
- Post-mortem examination revealed secondary missile (shrapnel) injuries on her legs.
- Embedded concrete fragments were found within the shrapnel wounds.
Findings:
- The shrapnel injuries were caused by concrete fragments propelled by the lightning strike impacting the pavement.
- This represents the first documented case of secondary missile formation (shrapnel injury) resulting from a lightning strike in scientific literature.
- The direct strike was the primary cause of death, with secondary missile injuries as a unique contributing factor.
Implications:
- Highlights the diverse and potentially severe injury mechanisms associated with lightning strikes.
- Underscores the importance of considering environmental factors and material interactions in forensic investigations of lightning fatalities.
- Suggests that protective measures against lightning should account for potential secondary projectile effects from surrounding materials.

Secondary Active Transport
137.4K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Secondary Healthcare System

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Secondary Distribution

Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
