Dead galaxies in Coma Cluster may be packed with dark matter, according to simulation

Galaxies in a cluster roughly 300 million light years from Earth could contain as much as 100 times more dark matter than visible matter, according to an Australian study. The research used computer simulations to study galaxies that have fallen into the Coma Cluster, one of the largest structures in the Universe in which thousands of galaxies are bound together by gravity.

Coryphopterus curasub: A fish too deep for science

Drs. Carole Baldwin and Ross Robertson from the Smithsonian Institution discovered a new small goby fish that differs from its relatives not only in its size and colors, but also in the depth of its habitat (70-80 m) in the southern Caribbean. Their finding comes as a part of the institution's Deep Reef Observation Project (DROP). This is why the scientists gave it the name Coryphopterus curasub in recognition of the Curasub submersible that was used in their deep-reef exploration.

Metal foams capable of shielding X-rays, gamma rays, neutron radiation

Metal foams capable of shielding X-rays, gamma rays, neutron radiation

Research from North Carolina State University shows that lightweight composite metal foams are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions. The finding means the metal foams hold promise for use in nuclear safety, space exploration and medical technology applications.

People are finally standing up to Gawker's gutter journalism

People are finally standing up to Gawker's gutter journalism

Over the past 24 hours, Gawker, the controversial gossip blog owned by Gawker Media, has earned some extraordinary and entirely justified opprobrium. It brought this on itself by posting a prurient and cruel story about the alleged sexual conduct of a finance executive employed by rival media company Condé Nast.

How to stop revenge porn - overhaul mainstream porn

The Press Association recently obtained new figures under Freedom of Information (FoI) laws, which show that police are dealing with their largest ever volume of revenge pornography cases. In the six months from October 2014 to April 2015, a total of 139 revenge porn allegations were made, on behalf of victims ranging from 11 years old, to over 60.

Nonmagnetic elements form unique magnet

Nonmagnetic elements form unique magnet

Titanium and gold are usually not magnetic and cannot be magnets – unless you combine them just so. Scientists at Rice University did so and discovered what is a first of its kind: an itinerant antiferromagnetic metal -- TiAu -- made from nonmagnetic constituent elements.

Diarrhea in cats

Barbara Hinney and her colleagues from the Institute for Parasitology at the University of Veterinary Medicine, Vienna, screened 298 faecal samples taken from cats across Austria for single-cell intestinal parasites, so called enteric protozoa. The samples came from private households, catteries and animal shelters. Of the 298 cats sampled, 56 tested positive with at least one intestinal parasite.

Multi-cat households often affected

A possible reason for drug resistance in breast tumors

HER2 membrane proteins play a special role in certain types of breast cancer: amplified levels of HER2 drive unrestricted cell growth. HER2-tailored antibody-based therapeutics aim to prevent cancer cell growth. However, two-thirds of HER2 positive breast cancer patients develop resistance against HER2-targeting drugs. The reason for this is not yet understood. Researchers now found out, that HER2 dimers appeared to be absent from a small sub-population of resting SKBR3 breast cancer cells.

Stem Cells Might Heal Damaged Lungs

Collectively, diseases of the airways such as emphysema, bronchitis, asthma, and cystic fibrosis are the second leading cause of death worldwide. More than 35 million Americans alone suffer from chronic respiratory disease. Weizmann Institute of Science researchers have now proposed a new direction that could, in the future, lead to the development of a method for alleviating some of the suffering of these patients. The study’s findings, which recently appeared in Nature Medicine, show how it might be possible to use embryonic stem cells to repair damaged lung tissue.

Dairy products boost effectiveness of probiotics

The success of probiotics for boosting human health may depend partly upon the food, beverage, or other material carrying the probiotics, according to research published on July 10th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
