The presence of water on Mars has been theorized for centuries. Early telescopes revealed ice caps, and early astronomers noted channels that were hypothesized to be natural rivers or creature-created canals. Over the past two decades, rovers Sojourner, Spirit, Opportunity, and Curiosity have sent back invaluable data to scientists who are trying to interpret the planet’s surface and uncover evidence of past or present water.

Since its landing on the “Red Planet” in August of 2012, Curiosity Rover has traveled about 20 kilometers within Gale Crater...

Phenylindanes in Brewed Coffee Inhibit Amyloid-Beta and Tau Aggregation. Frontiers in Neuroscience, 2018; 12 DOI: 10.3389/fnins.2018.00735

A new study out of the Krembil Brain Institute, part of the Krembil Research Institute, suggests there could be more to that morning jolt of goodness than a boost in energy and attention. Drinking coffee may also protect you against developing both Alzheimer’s and Parkinson’s disease. “Coffee consumption does seem to have some correlation to a decreased risk of developing Alzheimer’s disease and Parkinson’s disease,” says Dr. Donald Weaver, Co-director of the Krembil Brain Institute. “But we wanted to investigate why that is – which compounds are involved and how they may impact age-related cognitive decline.”

Dr. Weaver enlisted Dr...

A new high-tech bracelet, developed by scientists from the Netherlands detects 85% of all severe night-time epilepsy seizures. That is a much better score than any other technology currently available. The researchers involved think that this bracelet, called Nightwatch, can reduce the worldwide number of unexpected night-time fatalities in epilepsy patients. They published the results of a prospective trial in the scientific journal Neurology.

SUDEP, sudden unexpected death in epilepsy, is a major cause of mortality in epilepsy patients. People with an intellectual disability and severe therapy resistant epilepsy, may even have a 20% lifetime risk of dying from epilepsy...

The star, named 2MASS J18082002–5104378 B, is part of a two-star system orbiting around a common point.

Astronomers have found what could be one of the universe’s oldest stars, a body almost entirely made of materials spewed from the Big Bang. The discovery of this approximately 13.5 billion-year-old tiny star means more stars with very low mass and very low metal content are likely out there – perhaps even some of the universe’s very first stars.

The star is unusual because unlike other stars with very low metal content, it is part of the Milky Way’s “thin disk” – the part of the galaxy in which our own sun resides...
