Something is wrong with Einstein’s theory of gravity

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly … Read more

Undergrad publications theory on immune dysfunction in space

Frontiers in Cell and Developmental Biology (2022). DOI: 10.3389/fcell.2022.997365″ width=”782″ height=”530″/> Credit: Rocky An, Frontiers in Cell and Developmental Biology (2022). DOI: 10.3389/fcell.2022.997365 It’s been known for decades that though astronauts’ immune systems became suppressed in space, leaving them vulnerable to disease, the exact mechanisms of immune dysfunction have remained a mystery. Now a Cornell … Read more

Using game theory mathematics to resolve human conflicts

Game theory mathematics is being used to better understand and manage the social and environmental challenges of our times. Credit: © tulaidea, Shutterstock Game theory mathematics is used to predict outcomes in conflict situations.

New studies bolster theory coronavirus emerged from the wild

Residents line up to be tested for COVID-19 in Wuhan, central China’s Hubei province on Aug. 3, 2021. Two new studies provide more evidence that the coronavirus pandemic originated in a Wuhan, China market where live animals were sold – further bolstering the theory that the virus emerged in the wild rather than escaping from … Read more

A new theory of learning integrates cognitive psychology and systems biology

U and IC denote the US–US interval and the CS duration, respectively. In protocol 2, the US are presented at random with equal probabilities of occurring with or without the CS, and a CR does not develop. Protocols 3 and 4 are cue competition schemes involving multiple CSs. Protocol 3 has two phases: in the … Read more

Collapsing a leading theory for the quantum origin of consciousness

The Gran Sasso low radioactivity lab. Credit: Massimiliano De Deo, LNGS-INFN The origin of consciousness is one of the greatest mysteries of science. One proposed solution, first suggested by Nobel Laureate and Oxford mathematician Roger Penrose and anesthesiologist Stuart Hammeroff, at Arizona State University, in Tucson, attributes consciousness to quantum computations in the brain. This … Read more

Putting the theory of special relativity into practice, by counting galaxies

This image made from a composite of September 2003–January 2004 photos captured by the NASA/ESA Hubble Space Telescope shows nearly 10,000 galaxies in the deepest visible-light image of the cosmos, cutting across billions of light-years.
