Australian scientists have for the first time revealed how malaria parasites cause an inflammatory reaction that sabotages our body's ability to protect itself against the disease.
The bacterium B. cereus had so far been considered to be exclusively endospore-forming. In response to harsh conditions, the bacteria form protective endospores enabling them to remain dormant for extended periods. When conditions are more favourable, the endospores reactivate to become fully functioning bacteria.
Study calls for targeted efforts to address excess costs faced by those with a history of cancer.
According to a newly released report by the CDC, the birth of twins reached an all-time record number in 2014. 2014 saw 33.9 sets of twins per 1,000 births, versus 33.7 in 2013. It is believed that the increase is due to the increase in birth rates for older women. Scientist believe older women are actually more likely to have twins. They are also more likely to use IVF fertilization to conceive.

The back of a tiger could have been a blank canvas. Instead, nature painted the big cat with parallel stripes, evenly spaced and perpendicular to the spine. Scientists don't know exactly how stripes develop, but since the 1950s, mathematicians have been modeling possible scenarios. In Cell Systems on December 23, Harvard researchers assemble a range of these models into a single equation to identify what variables control stripe formation in living things.
New study offers recommendations for creating landscapes with year-round visual appeal.
Captivating with their bright, vivid and brilliantly metallic bodies, the cuckoo wasps are also fascinating with their curious lifestyle, which has given them this common name. However, in terms of their taxonomic grouping, they have been quite problematic due to similarities between species and a wide range of variations within them.
"Will you exercise this year?" That simple question can be a game-changing technique for people who want to influence their own or others' behavior, according to a recent study spanning 40 years of research.
A liver hormone works via the brain’s reward pathway to reduce cravings for sweets and alcohol in mammals, UT Southwestern Medical Center researchers have found.
Largest study ever of pulmonary hypertension could lead to easier treatment of the heart disease that most often affects young women. The oral medication Selexipag significantly reduced hospitalizations and worsening symptoms.
Reconstructing the magnitude of past volcanic eruptions is important in informing predictions about future eruptions and hazards. This is difficult to accomplish from records on land -- old eruptions are often eroded away, buried beneath later eruptions, or obscured by vegetation and soil. Most volcanoes are close to the oceans, so much of the erupted material falls into seawater and accumulates on the seafloor.
Geologists investigating an unusual landform in the Wabash River Valley in southern Illinois expected to find seismic origins, but instead found the aftermath of rushing floodwaters from melting Midwestern glaciers after the last ice age. The finding could give clues to how floodwaters may behave as glacier melt increases today in places like Greenland and Iceland.
A team of physicists from ITMO University, Ioffe Physical-Technical Institute and Australian National University have researched the phenomenon of phase transition between photonic crystals and metamaterials - two types of periodic structures capable of manipulating light in intricate ways. The study helps to gain an insight into the fundamental properties of periodic structures and opens new possibilities for the design and creation of new electromagnetic materials. The results of the study were published in Nature Communications.

Seen from the air, the peninsula that is home to the mid-Norway town of Ørland and the nation’s Main Air Station, looks like the head of a seahorse with its nose pointed south. It didn’t always look this way, though.
Fathers are able to adjust to increasing temperatures within their own lifetime and do transmit this information to their offspring. This has now been shown for the first time in a wild animal. The findings were the result of a project within the Joint Initiative for Research and Innovation and have been published in the scientific journal “Molecular Ecology.”
Sex-changing snails switch sooner when together.
A study led by Ángel Rubio, the UPV/EHU-University of the Basque Country professor and head of the Max Planck Institute in Hamburg, shows that it is possible to predict the effects of photons on materials.
Some reptiles such as crocodilians and some turtles are known to display temperature-dependent sex determination (TSD), where the ambient temperature of the developing eggs determines the individual's sex. For example in the American alligator's eggs, incubation at 33 ºC produces mostly males, while incubation at 30 ºC produces mostly females. An international joint research team between Japan and the US have determined that the thermosensor protein TRPV4 is associated with TSD in the American alligator. The research has been published in Scientific Reports.
