A process called ‘dark gulping’ may solve the mystery of the how supermassive black holes were able to form when the Universe was less than a billion years old.

Dr Curtis Saxton will be presenting the study at the European Week of Astronomy and Space Science at the University of Hertfordshire in Hatfield.

Researchers writing in Nature magazine say the fossil skeleton of a newly discovered carnivorous animal, Puijila darwini, is a "missing link" in the evolution of the group that today includes seals, sea lions, and the walrus. 

Modern seals, sea lions, and walruses all have flippers—limb adaptations for swimming in water. These adaptations evolved over time, as some terrestrial animals moved to a semi-aquatic lifestyle. Until now, the morphological evidence for this transition from land to water was weak.

Using information from a suite of telescopes, astronomers have discovered a mysterious, giant object that existed at a time when the universe was only about 800 million years old. Objects such as this one are dubbed extended Lyman-Alpha blobs; they are huge bodies of gas that may be precursors to galaxies. This blob was named Himiko for a legendary, mysterious Japanese queen. It stretches for 55 thousand light years, a record for that early point in time. That length is comparable to the radius of the Milky Way's disk. 

An international team of astronomers has used the world's biggest radio telescope to look deep into the brightest galaxies that NASA's Fermi Gamma-ray Space Telescope can see. The study solidifies the link between an active galaxy's gamma-ray emissions and its powerful radio-emitting jets. 

"Now we know for sure that the fastest, most compact, and brightest jets we see with radio telescopes are the ones that are able to kick light up to the highest energies," said Yuri Kovalev, a team member at the Max Planck Institute for Radio Astronomy in Bonn, Germany.

Take that, Taliban.   Western decadence, in the form of caring about beauty and nature, has infested your fundamentalist madness and it's here to stay.

We are talking about Band-i-Amir national park in Afghanistan, which opens today.

The United States Agency for International Development (USAID) provided key funding that led to the park's creation, including support of the Wildlife Conservation Society (WCS) to conduct preliminary wildlife surveys, identify and delineate the park's boundaries, and work with local communities and the provincial government. WCS also developed the park's management plan, helped the government hire and train local rangers, and provided assistance to the Afghan Government to design the laws enabling the park to be created. 

Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. The insight ultimately could lead to a cost-effective and energy-efficient strategy for turning biomass into alternative fuels.

In separate papers published today in Biophysical Journal and recently in an issue of Biomacromolecules, Los Alamos researchers identify potential weaknesses among sheets of cellulose molecules comprising lignocellulosic biomass, the inedible fibrous material derived from plant cell walls. The material is a potentially abundant source of sugar that can be used to brew batches of methanol or butanol, which show potential as biofuels.
