NASA’s MarCO mission was designed to find out if briefcase-sized spacecraft called CubeSats could survive the journey to deep space. Now, MarCO – which stands for Mars Cube One – has Mars in sight. One of the twin MarCO CubeSats snapped this image of Mars on Oct. 3 – the first image of the Red Planet ever produced by this class of tiny, low-cost spacecraft. The two CubeSats are officially called MarCO-A and MarCO-B but nicknamed “EVE” and “Wall-E” by their engineering team.

A wide-angle camera on top of MarCO-B produced the image as a test of exposure settings...

Black holes colliding, gravitational waves riding through space-time – and a huge instrument that allows scientists to investigate the fabric of the universe. This could soon become reality when the Laser Interferometer Space Antenna (LISA) takes up operations. Researchers have now found that LISA could also shed light on the elusive dark matter particle.

The Laser Interferometer Space Antenna (LISA) will enable astrophysicists to observe gravitational waves emitted by black holes as they collide with or capture other black holes. LISA will consist of three spacecraft orbiting the sun in a constant triangle formation...

Ames Laboratory has developed a method to measure magnetic properties of superconducting and magnetic materials that exhibit unusual quantum behavior at very low temperatures in high magnetic fields, by placing a tunnel diode resonator, an instrument that makes precise radio-frequency measurements of magnetic properties, in a dilution refrigerator, a cryogenic device that is able to cool samples down to milli-Kelvin temperature range.

Decades of research show a striking correlation between Alzheimer’s disease risk and infection with Herpes Simplex Virus 1 (HSV1) in people carrying a specific gene. Now, newly-available epidemiological data provide a causal link between HSV1 infection and senile dementia – raising the tantalizing prospect of a simple, effective preventive treatment for one of humanity’s costliest disorders.

Professor Ruth Itzhaki. Her latest paper presents a lifetime of research evidence that the herpes virus responsible for cold sores can also cause Alzheimer’s – and new data which show antiviral drugs drastically reduce risk of senile dementia in patients with severe herpes infections...
