What gravitational waves can say about dark matter
Symmetry Magazine - 18 Apr 2019 17:02
Scientists think that, under some circumstances, dark matter could generate powerful enough gravitational waves for equipment like LIGO to detect. In 1916, Albert Einstein published his theory of general relativity, whic...
Scientists invent way to trap mysterious 'dark world' particle at Large Hadron Collider
Phys.org - 18 Apr 2019 14:19
Now that they've identified the Higgs boson, scientists at the Large Hadron Collider have set their sights on an even more elusive target.
How the hepatitis B virus establishes persistent infection
Science Daily - 18 Apr 2019 20:52
New research sheds light on how a hepatitis B viral protein stimulates the expansion of immune cells that impair antiviral responses. The findings potentially explain how the hepatitis B virus (HBV) establishes and maint...
Does time of day affect the body's response to exercise?
Science Daily - 18 Apr 2019 20:17
New research confirms that the circadian clock is an important factor in how the body responds to physical exertion. Based on this work alone, it's too early to say when the best time is for you to go for a jog. But at l...
Genetic variants that protect against obesity could aid new weight loss medicines
Science Daily - 18 Apr 2019 20:17
Around four million people in the UK carry genetic variants that protect them from obesity, type 2 diabetes and heart disease, suggests new research. The team say the discovery could lead to the development of new drugs ...
Certain strains of bacteria associated with diabetic wounds that do not heal
Science Daily - 18 Apr 2019 20:16
Whether a wound -- such as a diabetic foot ulcer -- heals or progresses to a worse outcome, including infection or even amputation, may depend on the microbiome within that wound.
Study shows promise in repairing damaged myelin
Science Daily - 18 Apr 2019 20:16
A new study shows that a synthetic molecule stimulates repair of the protective sheath that covers nerve cells in the brain and spinal cord. The study demonstrates in mice that a synthetic molecule called sobetirome effi...
New immune pathway involved in resistance to parasite worms found in undercooked pork
Science Daily - 18 Apr 2019 20:16
Scientists have discovered that immune responses originally found to prevent fungal infections are also important in eliminating Trichinella spiralis, a round worm and the causative agent of Trichinosis. People acquire t...
Infection biology: Gut microbe helps thwart Salmonella
Science Daily - 18 Apr 2019 20:16
Researchers have identified a bacterial species in the gut microbiome of the mouse which protects against infection by human-pathogenic Salmonella.
Scientists advance creation of 'artificial lymph node' to fight cancer, other diseases
Science Daily - 18 Apr 2019 20:15
In a proof-of-principle study in mice, scientists report the creation of a specialized gel that acts like a lymph node to successfully activate and multiply cancer-fighting immune system T-cells. The work puts scientists...
RNA sequencing used to discover novel genes and pathways in celiac disease
