Researchers have discovered about 80 young galaxies in the early universe about 1.2 billion years after the Big Bang. They made detailed analyses of imaging data by the Hubble Space Telescope. Among them, 8 galaxies show double-component structures and the remaining 46 seem to have elongated structures. These results strongly suggest that galactic clumps in the young universe grow to become large galaxies through mergers.
People with leukemia could be helped by new research that sheds light on how the body produces its blood supply. Enabling scientists to grow the stem cells artificially from pluripotent stem cells could also lead to the development of personalized blood therapies, researchers say.
Remembering robots from film portrayals may help ease some of the anxiety that older adults have about using a robot, according to Penn State researchers.
Scientists have pieced together an early human habitat for the first time, and life was no picnic in Tanzania in East Africa 1.8 million years ago.
Someday soon, you may be able to log into your smartphone with sweeping gestures or doodling, using one or more fingers. Researchers have performed the first study of free-form gesture passwords for smartphones in the field. Such passwords allow people to draw a password of any shape with any number of fingers. Gesture, or doodling, passwords are very suitable for touchscreens, faster to use, easy to remember and hard to guess.
A new study suggests that cells construct protein 'clumps' to protect against neurodegenerative diseases such as amyotrophic lateral sclerosis, a.k.a. ALS or Lou Gehrig's disease.
Some patients with breast cancer, lung cancer and leukemia seem to fare poorly after treatment because of the effects of a particular gene, a new study finds. The gene, called CYP3A7, is normally only active in infancy, but in some people it continues to be switched on into adulthood, and over-activates their metabolism.
Mobility estimates may be more than 10 times too high. Overlooked source of electrical resistance implicated as the root of inaccuracies that can inflate estimates of organic semiconductor performance.
Hispanic women who identify as Black or another race have worse functional health than their counterparts who identify as White, according to new research.
Although breast cancer is somewhat more aggressive in South Asian and Black women than in White women, this is largely due to age differences between ethnic groups in the UK, according to new research. The findings suggest that inherent differences in tumor biology between the ethnic groups are unlikely to play a role.
Attention-deficit hyperactivity disorder (ADHD) is typically diagnosed in childhood and manifests as an inability to sustain attention and control activity levels and impulse control. Some reports have indicated a prevalence of up to 15 percent in Western countries. Although the causes of ADHD are still unknown, a new study found that a child's age at school entry may have an effect on the diagnosis of ADHD.
Undesirable associations with sex can be unlearned, but return if the circumstances change. They must therefore be unlearned in different situations, say researchers, noting that the drug D-cycloserine may help here.
Sequencing and comparative analysis of the genome of the Western Orchard predatory mite has revealed intriguingly-extreme genomic evolutionary dynamics through an international research effort. In a new study, the researchers detail the initial insights into several remarkable features of the genome of this agriculturally important mite that is widely employed to control plant pests, with thousands shipped to fruit growers every day.
The issue of global food security is a problem for us now, and for future generations. Perhaps the most visible issue is malnutrition, which affects millions in the developing world and poses a risk to many vulnerable people in the developed world. But the issue of global food security is much broader than the supply of food – it also refers to the challenges of our dependence on globally imported food, rising food prices, food waste and the provision of a nutritious, balanced diet.
Scientists investigated the levels of radioactive strontium and cesium in the coast off Japan in September 2013. Radioactive levels in seawater were 10 to 100 times higher than before the nuclear accident, particularly near the facility, suggesting that water containing strontium and cesium isotopes was still leaking into the Pacific Ocean.
Researchers have boosted the efficiency of water electrolysis. They applied a layer of copper atoms in a conventional platinum electrode. Thus, reaction intermediates could desorb a bit more easily from the catalyst surface. The modified system generated twice the amount of hydrogen than a platinum electrode without a copper layer.
An exceptional collection of bronze weapons dating from the Iron Age II (900-600 BC) has been uncovered near Adam, in the Sultanate of Oman. The remains were discovered scattered on the ground in a building belonging to what is thought to be a religious complex, during excavations carried out by the French archaeological mission in central Oman. In particular, they include two complete quivers and weapons made of metal, including two bows, objects that are for the most part non-functional and hitherto unknown in the Arabian Peninsula.
New research that sheds unprecedented light on the behavior of blasts produced by landmines and Improvised Explosive Devices (IEDs) could aid the development of enhanced protection for UK soldiers on military, peace-keeping and humanitarian missions.
Nights have been warming much faster than the days, observations from the last fifty years have shown. Analysis of the causes of this more rapid warming at night shows that this is likely to continue in the coming decades.
A new species of narrow-mouthed frog has been discovered in the laterite rock formations of India’s coastal plains. The frog, which is the size of a thumbnail, was named Microhyla laterite after its natural habitat.
