Buckyballs, largest known molecules in space, more common than thought
Observations made with NASA's Spitzer Space Telescope have revealed that buckminsterfullerenes, or 'buckyballs,' the largest known molecules in space, are more common than previously thought. ANI

Blood protein in lung cancer may help improve diagnosis, treatment
Scientists have discovered a protein in the blood of lung cancer patients that could be used in a test for the disease, which is difficult to diagnose in its earliest and most treatable stages, and to develop drugs that stop lung cancer from spreading. ANI

Potassium levels may explain racial disparity in Type 2 diabetes: Study
A new study suggests that lower potassium levels in the blood may help explain why African-Americans are twice as likely to be diagnosed with type 2 diabetes as whites. ANI

Retrovirus could be responsible for Lou Gherig's disease: Study
Johns Hopkins scientists say that a retrovirus, which inserted itself into the human genome thousands of years ago, may be responsible for some cases of the neurodegenerative disease amyotrophic lateral sclerosis (ALS), also known as Lou Gherig's disease. ANI

Flood-tolerant rice plants 'can also recover from drought'
Scientists at the University of California, Riverside have made a discovery that can greatly benefit rice growers and consumers everywhere. ANI

Good fungi might prove even better for the health of plants and humans
Scientists say they have come closer to understanding how a common fungus 'makes its living in the soil,' which could lead to its possible 'career change' as a therapeutic agent for plant and human health. ANI

Does fluoride really fight cavities?
Scientists are reporting that the protective shield fluoride forms on teeth is up to 100 times thinner than previously believed. ANI

How HIV affects brain function in its initial stages
Researchers have revealed that a new mouse model closely resembles how the human body reacts to early HIV infection and is shedding light on nerve cell damage related to the disease. ANI

New technology to make hair dyeing more natural, permanent
Experts predict that permanent hair dyeing will become longer lasting with more natural-looking dyes and gene therapy to reverse the gray.ost permanent hair colouring technology uses a 150-year-old approach that uses p-phenylenediamine (PPD), a chemical that produces darker, browner shades when exposed to air. ANI

How black holes can be used as models for superconductors
Physicists at the University of Illinois at Urbana-Champaign have shown how charged black holes can be used to model the behaviour of interacting electrons in unconventional superconductors. ANI

Study finds amplification of light pollution by clouds is large
A new study has found that clouds amplify ecological light pollution to a large extent. ANI

Global warming 'affecting food chain, carbon cycling in Arctic Ocean'
Over the past decade, the annual bloom of phytoplankton in the Arctic Ocean has been arriving earlier each year - a change that could hurt the marine food chain and carbon cycling in the region, according to a new research. ANI

2 new crustaceans found in Iberian Peninsula

Mystery over Sun's missing sunspots over 11-year cycle solved
Scientists have finally solved the mystery of the recent period of decreased solar activity during the Sun's 11-year cycle. ANI

Scientists use artificial, cell-like 'honey pots' to lure, trap deadly viruses
Scientists have found a novel way to trap a class of deadly human viruses - they have artificial "protocells" that can lure, entrap and inactivate them. ANI

NSAID use linked to increased risk of erectile dysfunction
Scientists have discovered that men who take non-steroidal anti-inflammatory drugs 3 times a day for more than three months are 2.4 times more likely to have erectile dysfunction compared to men who do not take those drugs regularly. ANI

Protein discovery could lead to better autoimmune disease, cancer drugs
The discovery that a single protein called FADD controls multiple cell death pathways could lead to better, more targeted autoimmune disease and cancer drugs. ANI

Depression after miscarriage can continue after healthy birth
A new study has found that women who experience depression and anxiety after a miscarriage can continue to experience these symptoms even if they subsequently go on to have a healthy child. ANI

Eating apples could extend lifespan by 10pc: Study
'An apple a day keeps the doctor away' is an old proverb. ANI
