Professor Stephen Hawking’s final theory on the origin of the universe, which he worked on in collaboration with Professor Thomas Hertog from KU Leuven, has been published in the Journal of High Energy Physics. The theory, which was submitted for publication before Hawking’s death earlier this year, is based on string theory and predicts the universe is finite and far simpler than many current theories about the big bang say...

Slight morphologic differences between terrestrial and Martian comparisons may be attributed to the great differences in age. Scale bar is 60 km long.

The climate of early Mars is a subject of debate. A recent study suggests that the early Martian surface may not have been dominated by ice, but instead it may have been modestly warm and prone to rain, with only small patches of ice...

New research published in Cancer Immunology Research by Drs. Esteban Celis and Hussein Sultan of the Georgia Cancer Center at Augusta University could serve as the stepping-stone in constructing vaccines with a greater likelihood of finding and attacking tumors in the human body. According to Celis and Sultan, the key in this vaccine strategy is increasing the amount of time a cytokine called interleukin 2 (IL2) stays in the body. IL2 is a molecule in the immune system responsible for regulating the activity of some white blood cells known as killer T cells.

“After administering peptide-based vaccines in mouse models of cancer, we ...

Calibrated Severity Scores (CSS), part of the Autism Diagnostic Observation Schedule (ADOS), measure ASD symptom severity based on clinical assessment.

Early diagnosis by ‘digital biomarkers’ may allow early intervention, better outcomes. Autism is challenging to diagnose, especially early in life. A new study in the journal Scientific Reports shows that inexpensive EEGs, which measure brain electrical activity, accurately predict or rule out autism spectrum disorder (ASD) in infants, even in some as young as 3 months.

“EEGs are low-cost, non-invasive and relatively easy to incorporate into well-baby checkups,” says C...
