A team of researchers has published a major list of celestial X-ray sources, which features over 150,000 high-energy stars and galaxies.

Using the X-ray telescope on board the US/UK/Italian Swift satellite, the team analyzed eight years’ worth of data to make the first Swift X-ray Point Source catalogue.

Researchers have suggested that the latest climate modelling suggests that the length of time carbon remains in vegetation during the global carbon cycle is the key “uncertainty” to predict how Earth’s terrestrial plant life – and consequently almost all life – will respond to higher CO2 levels and global warming.

When viewed with the human eye giant asteroid Vesta, looks quite unspectacular color-wise. However, when scientists at Max Planck Institute for Solar System Research in Katlenburg-Lindau, Germany re-analyzed the images of this giant asteroid obtained by Dawn’s framing camera, they assigned colors to different wavelengths of light and, in the process, revealed in unprecedented detail not only geological structures that are invisible to the naked eye, but also landscapes of incomparable beauty.

Two astronomers have proposed a new path for the formation of a newly discovered class of millisecond pulsars with similar orbital periods and eccentricities.

In the scenario of Paulo Freire and Thomas Tauris, a massive white dwarf star accretes matter and angular momentum from a normal companion star and grows beyond the critical Chandrasekhar mass limit.

However, it does not collapse immediately into a neutron star because it is rotating very fast and is thus sustained by centrifugal forces.

Researchers have developed a new robotic trolley system for providing patients, who are recovering from a stroke, spinal cord or brain injury, and orthopaedic injuries, added security to overcome the fear of falling, thereby maximizing benefit from therapy.

The risk and fear of falling often affects patients who are recovering from a stroke, spinal cord or brain injury, and orthopaedic injuries, and that fear may inhibit their progress in rehabilitation.

Researchers have found a way to create artificial replacement tissue that mimics both the strength and suppleness of native cartilage.

Articular cartilage is the tissue on the ends of bones where they meet at joints in the body – including in the knees, shoulders and hips. It can erode over time or be damaged by injury or overuse, causing pain and lack of mobility.

A new study has found that the lung lesions in an individual infected with tuberculosis (TB) are surprisingly variable and independent of each other, despite whether the patient has clinically active or latent disease.

The research could point the way to new vaccines to prevent the hard-to-treat infection.

Researchers have said insights into how the parasites, which cause the sleeping sickness, are able to communicate with one another could help limit the spread of the infection.

The findings suggest that new drugs could be designed to disrupt the flow of messages sent between these infectious microorganisms.

Sleeping sickness – so named because it disrupts sleep patterns – is transmitted by the bite of the tsetse fly. Untreated, it can damage the nervous system, leading to coma, organ failure and death.

Scientists have claimed that seawater could be used fuel up US Navy’s ships after they vowed to cut their petroleum use in half by 2015, and produce at least half of its jet fuel using alternative sources by 2020. According to Mashable, analytical chemist Heather Willauer is leading a study at the Naval Research Laboratory to develop the necessary technology that sucks up the gases to produce synthetic jet fuel for ships right out of the seawater they tread.

Is there any in-built self-control device for people who don’t know when and where to stop while talking to a colleague or chatting with a friend on social media? Well, there is – in your brain.

Neuroscientists at the University of Texas Health Science Centre at Houston (UTHealth) and the University of California, San Diego, have successfully demonstrated a technique to enhance a form of self-control through a novel form of brain stimulation.

Researchers have said that climate change is causing the location of North Pole location to drift.

Jianli Chen of the University of Texas at Austin and his team showed that melting of glaciers and ice sheets because of greenhouse-gas emissions is making its own contribution to the shift.

The wobble in Earth’s axis of rotation is a combination of two major components: Chandler wobble, thought to arise as Earth is not rigid, and another is the annual wobble, related to Earth’s orbit around the sun.

Scientists have long believed that DNA tells the cells how to make proteins. But the discovery of a new, second DNA code Thursday suggests the body speaks two different languages.

The findings in the journal Science may have big implications for how medical experts use the genomes of patients to interpret and diagnose diseases, researchers said.

The newfound genetic code within deoxyribonucleic acid, the hereditary material that exists in nearly every cell of the body, was written right on top of the DNA code scientists had already cracked.
