Nanotechnology makes it possible for mice to see in infrared

February 28, 2019

Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a new study. A single injection of nanoparticles in the mice’s eyes bestowed infrared vision for up to 10 weeks with minimal side effects, allowing them to see infrared light even during the day and with enough […]

Crater counts on Pluto, Charon show small Kuiper Belt objects surprisingly rare

February 28, 2019

Using New Horizons data from the Pluto-Charon flyby in 2015, scientists have indirectly discovered a distinct and surprising lack of very small objects in the Kuiper Belt. The evidence for the paucity of small Kuiper Belt objects (KBOs) comes from New Horizons imaging that revealed a dearth of small craters on Pluto’s largest satellite, Charon, […]

Bungee jumping for science

February 28, 2019

Immediately before a person decides to launch themselves off a bridge for a bungee jump, there is a measurable increase in their brain activity. This can be recorded nearly one second before the person makes the conscious decision to jump. Researchers have, for the first time, succeeded in measuring this ‘Bereitschaftspotential’ (readiness potential) outside a […]

Ant societies’ arms race: Gene activity in defenders depends on invading slavemaking ants

February 28, 2019

Temnothorax americanus is a slavemaking ant found in northeastern America. In a new study, biologists examined the special relationship between the parasites and their host and made an exciting discovery: The ability of the host ants to defend themselves depends crucially on whether the raiding slavemakers come from an area with a successful or less […]

Hiding black hole found

February 28, 2019

Astronomers have detected a stealthy black hole from its effects on an interstellar gas cloud. This intermediate mass black hole is one of over 100 million quiet black holes expected to be lurking in our Galaxy. These results provide a new method to search for other hidden black holes and help us understand the growth […]

New species of ‘golden death’ bacterium digests parasitic worms from the inside out

February 28, 2019

A new species of bacterium, Chryseobacterium nematophagum, has been found to digest its hosts — roundworm parasites — from the inside out. The findings suggest that the bacteria may potentially be used in future, to control roundworm infections in animals, plants, and, potentially, humans. Read More
