The most massive organism on Earth is shrinking

By ALLISON CHEN | October 31, 2018

The most massive organism on earth is not, as one might expect, a blue whale or a giant sequoia but a forest of quaking aspens. Pando, consisting of around 47,000 individual trunks spread across 106 acres, is a clonal colony whose source is a single male tree. The trunks are genetically identical and share a massive underground root system.

 PUBLIC DOMAIN Pando, a colony of aspens with one massive underground root system, has been shrinking.

Scientists discover traces of world’s oldest sponge

By JAEMIE BENNETT | October 31, 2018

From a cloud of dust came a planet, and on that planet came life. Life leaves its mark on Earth in the form of traditional fossils and trace fossils such as organic material, allowing scientists to study organisms that have been extinct for millions of years. A recent study has found evidence of multicellular life thriving on Earth up to 660 million years ago, 60 million years before what scientists previously believed.

PUBLIC DOMAIN Sponges are one of the simplest multicellular organisms found on Earth.

United Nations releases climate change report

By CHRIS REINHARDT | October 25, 2018

The discussions surrounding climate change have been heating up, so to speak. A recent report from United Nations (UN) scientists predicts that current efforts to curb global warming are not enough to prevent climate change from reaching dangerous levels. Only drastic action might be able to prevent a global crisis that may occur as early as 2040. 

CRISPR technology can be used to relocalize DNA

By SHIRLEY MARINO | October 25, 2018

At first sight, a cell’s DNA may look like a jumbled piece of string; however, it is actually highly organized. Through the use of clustered regularly interspaced short palindromic repeats (CRISPR), a gene-editing tool, researchers have discovered that the location of DNA is as vital as the sequence of base pairs in regards to how parts of the genome work.

Genetic ancestry sites may help solve crimes

By LAURA WADSTEN | October 25, 2018

Your Ancestry.com DNA report could help put your delinquent brother behind bars. The ability to utilize data in genetic ancestry databases to determine the identities of criminals is no longer something of science fiction. Investigators recently used DNA from a free online ancestry database to track down the infamous Golden State Killer, the man who killed 12 people and raped 45 women across California between 1976 and 1986.

Professor uses Tetris to study human vision

By ELIZABETH IM | October 25, 2018

There is an old saying in Korea: If your body is worth a thousand, your eyes are worth nine hundred.  As this phrase implies, visual perception is a very important part of our daily lives, even more than we may know. Vision dominates how we perceive the world, taking up more parts of our brain than any other human function. Chaz Firestone, an assistant professor in the Department of Psychological and Brain Sciences at Hopkins, studies vision in the Perception and Mind Lab.

Orca whales may hunt the same way mosasaurs did

By JAEMIE BENNETT | October 25, 2018

Until Jurassic World brought the mosasaur back to life on the big screen, the gigantic sea predator had been extinct for 65 million years, since the Cretaceous period. Mosasaurs were once the apex predators of the sea, and a recent study shows they may have hunted like the modern-day apex predator, the orca whale.

PUBLIC DOMAIN Mosasaurs lived in the same time period as tyranosaurus.

Evolutionary chemists win Nobel Prize

By ELAINE CHIAO | October 18, 2018

Darwin’s theory of evolution has been around for nearly 200 years, but its influence does not appear to subside with time. Not only is the topic of evolution a required biology curriculum in schools across the world, but it has also been cited in numerous research studies and papers. Today, it is still driving the forefront of molecular research. In fact, research conducted on the basis of Darwin’s theory of natural selection has recently led scientists to claim the 2018 Nobel Chemistry Prize.
