This image was taken at 3:38 a.m. EST on Feb. 9, 2017, when the spacecraft was 75 million miles from Earth and 419 million miles from Jupiter. With an exposure time of two seconds, the image renders Jupiter overexposed, but allows for enhanced detection of stars in the background. Credit: NASA/Goddard/University of Arizona

This magnified, cropped image showing Jupiter and 3 of its moons was taken by NASA’s OSIRIS-REx spacecraft’s MapCam instrument during optical navigation testing for the mission’s Earth-Trojan Asteroid Search. The image shows Jupiter in the center, the moon Callisto to the left and the moons Io and Europa to the right. Ganymede, Jupiter’s fourth moon, is also present in the image, but is not visible as it is crossing in front of the planet.

High-protein paternal diet confers an advantage to sons in sperm competition. Biology Letters, 2017; 13 (2): 20160914 DOI: 10.1098/rsbl.2016.0914

New research involving Monash University biologists has debunked the view that males just pass on genetic material and not much else to their offspring. Instead, it found a father’s diet can affect their son’s ability to out-compete a rival’s sperm after mating. The study sought to understand if the nutritional history of fathers had an effect on their sons. Experiments were carried out in the fruit fly, which shares many similar pathways and characteristics with human genes.

Dr Susanne Zajitschek from the School of Biological Sciences, said the study highlighted the importance of the paternal environment on future generations, even a long time b...

African Acacia Vachellia drepanolobium tree houses Tetraponera ant colonies inside hollow domatia. Formicamycins, antibacterial polyketides produced by Streptomyces formicae isolated from the plant-ants can combat MRSA

A new antibiotic, produced by bacteria found on a species of African ant, is very potent against antibiotic-resistant ‘superbugs’ like MRSA. Researchers at the University of East Anglia (UEA) and t

he John Innes Centre (JIC) discovered a new member of the Streptomyces bacteria family, isolated from the African fungus-growing plant-ant Tetraponera penzigi. They have named the new species Streptomyces formicae and the antibiotics formicamycins, after the Latin formica, meaning ant.

Lab tests have shown these new antibiotics are effective against methicillin resistant Staphyloc...

A new bilayer material, with each layer measuring less than one nanometer in thickness, someday could lead to more efficient and versatile light emission, such as bendy LED screens. Credit: Matthew Bellus

A new bilayer material, with each layer measuring < 1nm in thickness could lead to more efficient and versatile light emission. Researchers working at the Ultrafast Laser Lab at the University of Kansas successfully created the material by combining atomically thin layers of molybdenum disulfide and rhenium disulfide. “Both absorb light very well as semiconductors, and they’re both very flexible can be stretched or compressed,” said Hui Zhao, associate professor of physics and astronomy at KU...
