Bee body mass, pathogens and local climate influence heat tolerance      (via sciencedaily.com)     Original source 

How well bees tolerate temperature extremes could determine their ability to persist in a changing climate. But heat tolerance varies between and within populations, so entomologists examined bee physical traits to understand how these traits interact with environmental conditions, pathogens and other factors.

Hubble views a galaxy with a voracious black hole      (via sciencedaily.com)     Original source 

Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).

Protecting endangered monkeys from poachers, habitat loss      (via sciencedaily.com)     Original source 

The 17 species of red colobus monkey living across Africa, including in the Tai Project field station region, have been singled out by scientists as a priority conservation target. Protection of these monkeys, they assert, can be expected to produce benefits throughout tropical African forests where hunting and climate change have led to dramatic wildlife and habitat loss.

Eruption of mega-magnetic star lights up nearby galaxy      (via sciencedaily.com)     Original source 

While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.
