Scientist Spotlight: Henry Paulson, M.D., Ph.D.

Written by: Isha Verma, Ph.D.

Alzheimer’s disease (AD) is a neurodegenerative disease that causes the shrinkage of the brain and the death of the brain cells resulting in dementia, disorientation, mood swings, and other behavioral issues. These changes result in the loss of the person’s ability to function properly, ultimately resulting in death. About 6.5 million people in the United States age 65 and older live with AD. AD is associated with extracellular deposits of amyloid beta proteins (amyloid plaques), hyperphosphorylated Tau protein aggregates (neurofibrillary tangles), and loss of neuronal connections in the brain. Other risk factors include head injury, clinical depression, and high blood pressure.

Dr. Henry Paulson

In honor of Alzheimer’s and Brain Awareness Month (June), we talked to Dr. Henry Paulson, M.D., Ph.D., one of the leading AD researchers. Dr. Paulson is Lucile Groff Professor of Neurology at the University of Michigan and Director of Michigan Alzheimer’s Disease Center.

¿Cómo los bioplásticos pueden reducir nuestra dependencia de los plásticos en el laboratorio?

Nuevos artículos de investigación son publicados a diario, reportando avances en todos los campos de la ciencia. Sin embargo, la ciencia no puede ocurrir sin el equipamiento y materiales apropiados, muchos de los cuales están hechos de plástico. ¿Por qué? El plástico es usualmente el material disponible más barato y es más seguro que la cristalería, la cual tiene una mucha más alta probabilidad de romperse. Un estudio realizado en la Universidad de California – Santa Bárbara encontró que el 80% de los desechos plásticos de laboratorios en MIT consiste solamente de cajas de puntas de pipetas. Un laboratorio de microbiología en Edimburgo, Reino Unido, encontró que en el plazo de cuatro semanas, produjeron 97 kg (213.8 lbs) de desechos plásticos. Utilizar plástico no es inherentemente malo, especialmente debido a que existen muchos recursos disponibles y regulaciones (tanto locales como estatales) para el reciclaje y el reuso de desechos plásticos. Sin embargo, el volumen de los desechos plásticos que no se pueden reciclar generado en laboratorios alrededor del mundo es masivo, y pareciera un problema imposible de resolver. Es aquí donde entran los bioplásticos.

Scientist Spotlight: Dr. Eva Feldman

Amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease, is a neurological disease that causes the degeneration and death of the nerves controlling the muscles, called motor neurons. This results in gradual muscle wasting and loss of the ability to walk, talk, eat, and, eventually, breathe. The typical survival is 3 to 5 years from the onset of symptoms. ALS occurs in approximately 1 to 4 of every 100,000 individuals, and over 30,000 individuals in the United States are estimated to be living with ALS.

时值1633年，天文学家伽利略·伽利莱由于他的异端思想“地球围绕着太阳公转”而被软禁在家。虽然今天的伽利略被视为现代科学之父之一， 但在当时的罗马天主教会裁决中他被认为是“极其可疑的异端”（即认定其支持异端学说）。

The neuroscientific study of consciousness: How did we get here?

Written by: Rachel Wahlberg

Edited by: Olivia Pifer Alge, Austin Shannon, Andrés Rivera Ruiz, and Jennifer Baker 

Illustrated by: Hana Paz Harbman 

This blog post is part 1 of a multi-piece series on the neuroscientific study of consciousness. Stay tuned for parts 2 and 3 coming soon! 

If I were to walk up to you on the street and ask you if you were conscious, what would you say? My guess is you would answer with a “well, yes?” – and if you’re anything like me, with a nervous laugh added, wondering what sort of conversation you’ve just walked into.

The Pesticide Paradox: How Modern Agriculture is Both Feeding and Poisoning the World

Written and illustrated by: Nia Johnson

Edited by: Sophie Hill, Henry Ertl, Jessica Li, and Jennifer Baker

Have you ever wondered how we are able to feed nearly 8 billion people globally? Presently, agricultural lands make up the world’s largest biome, covering over 1/3 of the ice-free land area. According to the United Nations Food and Agriculture Organization, these 5 billion hectares of land produce around 550 billion tons of crops annually. This is equivalent in weight to 110,000 Empire State Buildings each year! Agriculture is not only a major source of income for 40% of the world’s population, but it also makes up 30% of GDP in low-income countries. While technological advances and agricultural expansion are projected to keep up with the rising pressures of human population growth (about 10 billion people by 2050), the unintended impacts of modern agriculture have advocacy groups and scientists alike concerned about the long-term consequences.

Joseph Wedekind: Redefining Riboswitches

You may recall learning in high school biology that ribosomes are the smallest organelle. Despite their miniscule size, these organelles are one of the most critical – that’s why they, unlike some organelles, are present in both eukaryotes and prokaryotes. The site of protein synthesis in the cell, ribosomes are responsible for building proteins that dictate our bodily metabolic activity, and ultimately, who we are.

Amy Gladfelter: Encoding temperature sensitivity in biomolecular condensates

The nucleus, the endoplasmic reticulum, and the mitochondria are organelles likely familiar to many of us from biology class. These structures are separated from the rest of the cell by membranes and are used by eukaryotic cells to compartmentalize and organize molecules that support specific cell functions. While these organelles are certainly important, Dr. Amy Gladfelter and her group are interested in a different kind of cellular organization: biomolecular condensates.

Geraldine Seydoux: Regulation of biomolecular condensates by interfacial protein clusters

Live blogger: Paul Dylag

Editor: Jennifer Baker

Biomolecular condensates are found throughout plant and animal cells in various organelles that lack membranes, such as the nucleolus and RNA granules. Normally, membraneless organelles would be an issue, as mixing their components with cytoplasm or extracellular fluid may result in mutations. However, there must be some chemical agents that prevent this, as otherwise life would not have evolved to such complex levels. Researchers are still investigating what prevents these issues from occurring, but one category of molecules called pickering agents have been determined to play a key role in this process.
