Khabarovsk Krai, a territory occupying the coastline of the Sea of Okhotsk, is on fire. Dozens of red hotspots, accompanied by plumes of smoke mark active fires. The smoke, which appears mostly white or grey, blows to the east towards the Sea of Okhotsk.

Taiga and tundra are found in the north of this area, swampy forest inhabit the central depression, and deciduous forests are the natural vegetation in the south.

Gravitational waves are phenomena predicted by Einstein's theory of General Relativity but no one has ever observed them and their discovery would have profound implications for the study of the Universe.

Last March, the team behind the BICEP2 project made a ground-breaking announcement: the Antarctic observatory had detected a signal referable to gravitational waves. The study said they excluded possible contaminants - other sources that could have generated the same signal - and that the observation was valid.

Do kids of "tiger moms" - the term used by culture for demanding mothers in Asian families and   popularized due to the 2011 book "Battle Hymn of the Tiger Mother" by Amy Chua - have lower self-esteem?

Not if the halls of Caltech are any indication. And do we need more young people with high levels of self-esteem living with their parents in their 30s? Regardless, a new paper in 
the Journal of Family Issues finds that less supportive and punitive parenting techniques used by some Chinese parents might lead to the development of low self-esteem and school adjustment difficulties, leaving kids vulnerable to depression and problem behaviors.

In a global warming scenario, large areas of sea ice melt in the summer and when sea ice freezes over in the winter it is thinner and more reduced.

But warmer Arctic summers could lead to an acceleration of global warming, because reduced sea ice in the Arctic will remove less CO2 from the atmosphere, Danish scientists report.

"If our results are representative, then sea ice plays a greater role than expected, and we should take this into account in future global CO2 budgets", says Dorte Haubjerg Søgaard, PhD Fellow, Nordic Center for Earth Evolution, University of Southern Denmark and the Greenland Institute of Natural Resources, Nuuk.

Three weeks ago, well-known feminist gaming critic Anita Sarkeesian was forced to leave her San Francisco home due to an ongoing tirade of abuse and threats. Members of a vocal minority of online trolls had threatened to kill her parents, drink her blood, and rape her – all while publishing her personal details online.

Carbon dioxide emissions, the greenhouse gas that has been most strongly implicated in global warming, will reach a record high of 40 billion tons.

Physicists at the University of Geneva have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber.

The experiment shatters the previous record of 6 kilometers achieved 10 years ago by the same  team. Passing from light into matter, using teleportation of a photon to a crystal, shows that, in quantum physics, it is not the composition of a particle which is important, but rather its state, since this can exist and persist outside such extreme differences as those which distinguish light from matter.

The latest experiments have enabled verifying that the quantum state of a photon can be maintained whilst transporting it into a crystal without the two coming directly into contact.

Breast cancer experts around the world have issued a plea to researchers, academics, drug companies, funders and advocates to carry out high quality research and clinical trials for advanced breast cancer, a disease which is almost always fatal and for which there are many unanswered questions.

In the latest international consensus guidelines for the management of advanced breast cancer, published simultaneously in the leading cancer journals The Breast and Annals of Oncology [1] today (Friday), the experts say that further research and clinical trials are "urgently needed" to find the best treatments for:

• patients with breast cancer that has spread to the liver, or the space around the lungs (pleural cavity) or the skin;
