Published Harnessing power of immune system may lessen reliance on antibiotics for infections like TB
(via sciencedaily.com) 
Researchers have found that the body's process of removing old and damaged cell parts, is also an essential part of tackling infections that take hold within our cells, like TB. If this natural process can be harnessed with new treatments, it could present an alternative to, or improve use of antibiotics, especially where bacteria have become resistant to existing drugs.
Published Newly discovered cell in fruit flies is essential for touch sensation
(via sciencedaily.com) 
Researchers have uncovered a key role for a new type of cell in touch detection in the skin of the fruit fly.
Published Researchers discover a way to fight the aging process and cancer development
(via sciencedaily.com) 
Damage in the human genome can be repaired. But this works better in germ cells, sperm and eggs, than in normal body cells. Responsible for this is the DREAM protein complex, which prevents the activation of all available repair mechanisms. A research team has now shown that normal body cells can also be repaired better once this complex has been deactivated. In the long run, the scientists hope to develop better therapies to prevent cancer and aging-associated diseases.
Published Pressure-based control enables tunable singlet fission materials for efficient photoconversion
(via sciencedaily.com) 
Applying hydrostatic pressure as an external stimulus, researchers demonstrate a new way to regulate singlet fission (SF), a process in which two electrons are generated from a single photon, in chromophores, opening doors to the design of SF-based materials with enhanced (photo)energy conversion. Their method overrides the strict requirements that limit the molecular design of such materials by realizing an alternative control strategy.
Published Without this, plants cannot respond to temperature
(via sciencedaily.com) 
Scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair.
Published Genome of a drought-tolerant plant: Many genes are involved in 'resurrection'
(via sciencedaily.com) 
Some plants can survive months without water, only to turn green again after a brief downpour. A recent study shows that this is not due to a 'miracle gene.' Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.
Published Robotic system offers hidden window into collective bee behavior
(via sciencedaily.com) 
Researchers have developed a temperature-modulating robotic system that can be seamlessly integrated into notoriously sensitive honeybee hives, providing both a never-before-seen view of honeybee behavior and a means to influence it.
Published Geoscientists shed a light on life's evolution 800 million years ago
(via sciencedaily.com) 
Is nitrate responsible for algae, flowers, and even your neighbors? A team of geoscientists have unearthed evidence that may indicate yes.
Published Memory B cell marker predicts long-lived antibody response to flu vaccine
(via sciencedaily.com) 
Memory B cells play a critical role to provide long-term immunity after a vaccination or infection. Researchers have now described a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans. These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later.
Published Babies or beauty? Ancient origin of how female butterflies invest
(via sciencedaily.com) 
When resources are scarce, most animals have to choose. A new study reveals an ancient origin to how female butterflies invest.
Published Towards reducing biodiversity loss in fragmented habitats
(via sciencedaily.com) 
By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.
Published Researchers create artificial enzyme for fast detection of disease-related hormone in sweat
(via sciencedaily.com) 
Researchers have developed a handheld sensor that tests perspiration for cortisol and provides results in eight minutes, a key advance in monitoring a hormone whose levels are a marker for many illnesses including various cancers.
Published Sea otters killed by unusual parasite strain
(via sciencedaily.com) 
An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.
Published Sweets change our brain
(via sciencedaily.com) 
Chocolate bars, chips and fries - why can't we just ignore them in the supermarket? Researchers have now shown that foods with a high fat and sugar content change our brain: If we regularly eat even small amounts of them, the brain learns to consume precisely these foods in the future.
Published Photosynthesis 'hack' could lead to new ways of generating renewable energy
(via sciencedaily.com) 
Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
Published New mosquito species reported in Florida
(via sciencedaily.com) 
A mosquito known only by its scientific name, Culex lactator, is the latest to establish in the Sunshine State, according to a new study.
Published Novel drug makes mice skinny even on sugary, fatty diet
(via sciencedaily.com) 
Deleting a gene that promotes magnesium transport into mitochondria (which are cells' power plants) resulted in more efficient metabolism of sugar and fat in the energy centers. The result: skinny, healthy mice. Now the research team, has developed a small-molecule drug that accomplishes the same effect in mice.
Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated
(via sciencedaily.com) 
Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published To ward off aging, stem cells must take out the trash
(via sciencedaily.com) 
Researchers find stem cells use a surprising system for discarding misfolded proteins. This unique pathway could be the key to maintaining long-term health and preventing age-related blood and immune disorders.
Published How the 'marsupial sabertooth' thylacosmilus saw its world
(via sciencedaily.com) 
A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow or a horse. The skulls of carnivores typically have forward-facing eye sockets, or orbits, which helps enable stereoscopic (3D) vision, a useful adaptation for judging the position of prey before pouncing. Scientists studied whether the 'marsupial sabertooth' Thylacosmilus atrox could see in 3D at all.
