As a student of zoology, I will always advocate for critical thinking of how basic processes are expressed and utilized across organisms, and recommend excursions and adventures that bring to life the incredible science that makes up life on Earth!" - Trinity Garcia, senior at Texas A&M ...
Some marine protozoans (single-celled organisms), called foraminifera, have shells that tell the temperature of the water where the animal lived. By studying the chemical make-up of these tiny fossils, the temperatures of prehistoric seas can be found, and changes in the ocean temperature can ...

several neurodegenerative diseases, including Alzheimer's, Parkinson's and Huntington's disease. The proteins that connect and bridge the ER and mitochondria are well-studied in yeast, but the connections between these organelles in multicellular organisms like mammals are more complex and less ...
“An economic community supported by a foundation of interacting organizations and individuals – the organisms of the business world. The economic community produces goods and services of value to customers, who are themselves members of the ecosystem. The member organisms also include suppliers, lead...
The question is “what came first, the Universe or Life?” A chicken and egg problem, to be sure, but easily resolved. Since Universe could not have developed *at random*, without some plan and intelligent direction, we must assume that Life came first. We might say that Universe IS Lif...

Having travelled from the outer reaches of our Solar System, this organic matter ended its journey in the oceans of primitive Earth. Now we need to know what the environmental parameters were which allowed this matter to keep reassembling until it formed living organisms.这些有机物从太阳系的外围...
