Human stomach pathogen is attracted to bleach
- ScienceDaily
- 19/8/29 21:20
Researchers have uncovered a molecular mechanism by which the human stomach pathogen Helicobacter pylori is attracted to bleach. The study revealed that H. pylori uses a protein called TlpD to sense bleach and swim toward it. The researchers propose H. pylori uses the protein to sense sites of tissue inflammation, which could help colonize the stomach and perhaps locate damaged tissue and...
Crouching lion, hidden giraffe

The behavior of giraffe groups with calves is influenced more strongly by the risk of predators than is the behavior of all-adult groups, which is mostly determined by the availability of food.
First all-metamaterial optical gas sensor
- ScienceDaily
- 19/8/29 21:08
Researchers have developed the first fully-integrated, non-dispersive infrared (NDIR) gas sensor enabled by specially engineered synthetic materials known as metamaterials. The sensor has no moving parts, requires little energy to operate and is among the smallest NDIR sensors ever created.

- 19/8/29 21:08
A new method for permanently marking cells infected with chikungunya virus could reveal how the virus continues to cause joint pain for months to years after the initial infection, according to a study.
How visceral leishmaniasis spread through central-Southern Brazil
- ScienceDaily
- 19/8/29 21:08
The protozoan disease visceral leishmaniasis (VL) has recently expanded to places where it had not previously been reported and has expanded its geographic distribution within countries where it was already endemic. Now, researchers describe three dispersion routes that have moved Leishmania infantum into and through central-Southern Brazil, helping shed light on the overall mechanisms of VL...
Cracking the code of a brain cancer that keeps coming back
- ScienceDaily
- 19/8/29 21:08
Researchers used a powerful new computer-assisted technology called single-cell transcriptomics that measures thousands of individual cells simultaneously to map cell types and molecular cascades that drive the growth of SHH-medulloblastoma. The scientists report they discovered new treatment strategies for the disease that may help patients fight a recurrent cancer.
This protein is how creatures sense cold

Researchers have identified a receptor protein that can detect when winter is coming.
Gene therapy reduces obesity and reverses type 2 diabetes in mice
- ScienceDaily
- 19/8/29 21:07
The obesity epidemic affects nearly half a billion people worldwide, many of them children. Obesity-related diseases including heart disease, stroke, type 2 diabetes, and cancer are a leading cause of preventable death. Researchers have now developed a gene therapy that specifically reduces fat tissue and reverses obesity-related metabolic disease in obese mice.
Deep-sea sediments reveal solar system chaos: An advance in dating geologic archives
- ScienceDaily
- 19/8/29 21:07
Scientists used geologic records from deep-sea drill cores to extend the astronomical time scale beyond 50 million years, by about 8 million years. Using their new chronology, they provide a new age for the Paleocene-Eocene boundary (56.01 Ma) with a small margin of error (0.1%).
Synthesis of UV absorbers from cashew nut shell liquid
- ScienceDaily
- 19/8/29 21:07
Researchers succeeded in using cashew nut shell liquid (CNSL) as a substitute for petroleum in organic synthesis. Their aim was the development of a sustainable synthesis of soluble organic UV filters.
Entanglement sent over 50 km of optical fiber
- ScienceDaily
- 19/8/29 21:07
For the first time, a team has sent a light particle entangled with matter over 50 km of optical fiber. This paves the way for the practical use of quantum networks and sets a milestone for a future quantum internet.
Global warming may diminish plant genetic variety in Central Europe

Only a few individuals of a plant species may be prepared for increasing droughts.
Better chemistry through tiny antennae
- ScienceDaily
- 19/8/29 21:07
A research team has developed a new method for actively controlling the breaking of chemical bonds by shining infrared lasers on tiny antennae. This research may have applications in improving the yields of chemical reactions.
A protective factor against Alzheimer's disease?
- ScienceDaily

Researchers have found that a protein called TREM2 could positively influence the course of Alzheimer's disease.
Marathoners, take your marks...and fluid and salt!
- ScienceDaily
- 19/8/29 21:07
Legend states that after the Greek army defeated the invading Persian forces near the city of Marathon in 490 B.C.E., the courier Pheidippides ran to Athens to report the victory and then immediately dropped dead. The story -- and the distance Pheidippides covered -- inspired the modern marathon, a grueling 26.2-mile contest that attracts some 1.3 million runners annually to compete in the more...
Lack of oxygen doesn't kill infant brain cells
- ScienceDaily
- 19/8/29 21:07
Research raises new concerns about the vulnerability of the preterm brain to hypoxia. Results confirm that brain cells do not die as previously believed. Rather, hippocampal cells fail to mature normally, causing a reduction in long-term potentiation, or the cellular basis of how the brain learns.

- 19/8/29 21:07
As issues like climate change, global warming, and renewable energy dominate the national conversation, it's easy to assume these topics are exclusive to the modern world. But a huge collaborative study in Science reveals that early humans across the entire globe were changing and impacting their environments as far back as 10,000 years ago.

Every animal contains in their genome pieces of DNA called Hox genes. Architects of the body, these genes are keepers of the body's blueprints. Scientists have long searched for a key to decoding this body map. Now researchers have found one such key: a method that can systematically identify the role each Hox gene plays in a developing fruit fly. Their results offer a new path forward for...
