Tropical Cyclone Hudhud formed on Oct. 8th and began moving from east to west across the Bay of Bengal in the Northern Indian Ocean. 
NASA's Aqua satellite flew over Hudhud today and took a picture of the storm that showed it was still somewhat elongated, but more organized than the previous day. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Aqua satellite provided the hint of a developing eye.
Warnings for winds, rain and surf are already in effect for the northern Andhra Pradesh coast and south Odisha coastline of eastern India as Hudhud approaches.

No matter what type of chemotherapy you attack a tumor with, many cancer cells resort to the same survival tactic: They start eating themselves. This autophagy process happens when two proteins pair up and switch it on this process, according to a new paper.
"This gives us a therapeutic avenue to target autophagy in tumors," says Brigham Young University chemistry professor Josh Andersen. "The idea would be to make tumors more chemo-sensitive. You could target these proteins and the mechanism of this switch to block autophagy, which would allow for lower doses of chemotherapy while hopefully improving patient outcomes."

The evolution of new traits with novel functions has long been studied by evolutionary biology and a new study of the color markings of cichlid fish has shed some new light on it.
Swiss scientists writing in Nature Communications show what triggered these evolutionary innovations, namely: a mobile genetic element in the regulatory region of a color gene.  

Sometimes organic food kills and there is nothing more natural than locally-hunted wild meat bought at a local market. 
Now it turns out that ebola, as with many emerging infections, may have arisen due to the practice of eating wild meat known as 'bushmeat', say a team of researchers led by the University of Cambridge and the Zoological Society of London. They surveyed almost 600 people across southern Ghana about their bat bushmeat consumption – and how people perceive the risks associated with the practice.

Elephants are among the most intelligent non-humans, arguably on par with chimpanzees, and both African and Asian elephants are endangered. 
In 1995, 16-month old Kumari, the first Asian elephant born at the National Zoo in Washington, DC, died of a mysterious illness. In 1999, Gary Hayward of Johns Hopkins University and collaborators published their results identifying a novel herpesvirus, EEHV1 as the cause of Kumari's sudden death. They now show that severe cases like this one are caused by viruses that normally infect the species, rather than by viruses that have jumped from African elephants, which was their original hypothesis.  

A once-in-a-century supernova, dubbed SN2014J, in a the nearby galaxy Messier 82 - the Cigar Galaxy - 12 million light-years away has been spotted; a pulsating dead star beaming with the energy of about 10 million suns. The object, previously thought to be a black hole because it is so powerful, is in fact a pulsar - the incredibly dense rotating remains of a star. 
Dom Walton, a postdoctoral scholar at Caltech who works with NuSTAR data, says that with its extreme energy, this first ultraluminous pulsar takes the top prize in the weirdness category. Pulsars are typically between one and two times the mass of the sun. This new pulsar presumably falls in that same range but shines about 100 times brighter than theory suggests something of its mass should be able to.

Despite the publicity of high-profile celebrities having their iPhones hacked and private pictures distributed across the Internet, a new paper confirms that substantial numbers of teens are sexting – sending and receiving explicit sexual images via cellphone. Though the behavior is widely studied, the potentially serious consequences of the practice led the researchers to more accurately measure how frequently teens are choosing to put themselves at risk in this fashion.

The NASA satellites, Tropical Rainfall Measuring Mission (TRMM) and Terra, have provided data on clouds, rainfall and the diameter of the eye of Super Typhoon Vongfong as it turned north in the Northwestern Pacific Ocean.
Typhoon Vongfong formed on October 2nd, 2014 in the southeast of Guam. Typhoon Phanfone, that recently pummeled Japan, formed near the same area in the western Pacific Ocean.

What could the natural diversity and beauty of plant leaves have in common with the violin, one of mankind's greatest musical inventions? More than you think.

Dan Chitwood, Ph.D., assistant member, Donald Danforth Plant Science Center in St. Louis, Missouri
spends most of his time exploring genetic and molecular mechanisms underlying diversity in plant morphology - how leaf shapes are formed and what that means for a plant to grow and thrive. He also studies how leaf shapes change as plant species evolve to adapt in different environments. Research into why a desert-adapted tomato species can survive with little water, for example, sheds light on how leaf architecture affects the efficiency of plant water use. 

Gamma rays are the highest-energy form of radioactive waves known in the universe but how they're made and where they come from have been something of a mystery. 
Using highly detailed radio telescope images, a team of astronomers have pinpointed the location where an explosion on the surface of a star, known as a nova, emitted gamma rays.  A nova occurs in a star that is part of a binary system – two stars orbiting one another. One star, known as a dense white dwarf, steals matter from the other and the interaction triggers a thermonuclear explosion that flings debris into space.

It was from this explosion from a system known as V959 Mon, located some 5,000 light years from Earth, that the researchers think the gamma rays were emitted.

"Keeping up with the Joneses" is a colloquialism for developing world desire to have the same or better status in society than peers. If someone gets a new car, you get a new car.
In some people, status is so important they suffer psychological distress if they lack status.
But it isn't just for the middle class in Western nations, say anthropologists at U.C. Santa Barbara, who found that the same need exists among the Tsimane, an egalitarian society of forager-farmers in the Bolivian Amazon. 

Adolescence is often a turbulent time for both genders, marked by biological changes and substantially increased rates of depressive symptoms.
But girls seem to take it a lot harder and a new paper in Clinical Psychological Science believes this gender difference may be the result of girls' greater exposure to stressful interpersonal events, making them more likely to ruminate, and contributing to their risk of depression.
