Future robots won't resemble humans – we're too inefficient

Humanoid robots are a vanity project: an attempt to create artificial life in our own image – essentially trying to play God. The problem is, we're not very good at it. Ask someone on the street to name a robot and you might hear "Terminator", "the Cybermen" or "that gold one from Star Wars". What you're not going to be given are names like Tesla Model X, Cassini or DJI Inspire 2. These are all robots, but they don't follow the sci-fi narrative of what robots should be like. The fact is, the robots of the near future won't be going about on two legs like the shuffling C3PO. And they'll be much more efficient than us bipeds.

Software vastly improves the ability of ships to reroute through unpredictable weather

Regulating asprosin levels might help control appetite and weight

Less than two years ago, researchers led by Dr. Atul Chopra, a medical geneticist at Baylor College of Medicine, discovered a new hormone called asprosin, that regulates blood-glucose levels. New studies on the hormone have now revealed that asprosin also acts on the brain, stimulating the hunger center in the hypothalamus to control appetite and body weight. This opens an intriguing possibility for developing novel treatments for overweight people, a population for whom no effective medical therapies currently exist. The study appears in the journal Nature Medicine.

Imaging may provide a new tool to track progression of calcific aortic-valve disease

Almost a half million Americans aged 65 to 74 suffer from a degenerative cardiovascular disease caused by calcium being deposited in heart tissue, and many will need valve replacement surgery to prevent heart failure.

How Helicobacter pylori causes gastric cancer

Gastric cancer is one of the five most fatal types of cancer. According to the statistics of the World Health Organization (WHO), about 750,000 patients die each year after developing the disease. The main cause is thought to be the bacterium Helicobacter pylori (H. pylori). At present, there are no effective therapies for gastric cancer and growing spread of antibiotic resistances is further complicating treatment of the infection. Researchers at FAU have now identified two mechanisms through which this bacterium can cause gastric cancer. Their findings could result in the development of new therapeutic approaches. The team has published its results in the leading journal Cell Host & Microbe.

Study shows nearly 70 percent of cannabidiol extracts sold online are mislabeled

In recent years, there has been an increased interest in the medicinal use of Cannabidiol (CBD), a chemical that naturally occurs the in cannabis plant (aka "marijuana"). There is interest in CBD as a medicine because there is some evidence that it has medical benefits, but it does not make people feel "high" and there is no indication that CBD, by itself, is abused. Recent research has shown potential therapeutic effects of CBD for young children with rare seizure disorders, and patients in states where cannabis or CBD have been legalized report using it for a variety of health conditions. Business experts estimate that the market for CBD products will grow to more than $2 billion in consumer sales within the next three years. While interest in this area continues to grow, little has been done to ensure regulation and oversight of the sale of products containing CBD. The primary reason for this is that CBD is currently classified as a Schedule I controlled dangerous substance by the DEA, despite having been legalized for medicinal use in many states. Thus, many people do not have access to stores that sell CBD products and instead rely on online retailers to purchase CBD products.

Clinical trial reveals low-fat diet is associated with reduced pancreatic cancer incidence in overweight women

Lending late neurons a helping hand

During the foetal stage, millions of neurons are born in the walls of the ventricles of the brain before migrating to their final location in the cerebral cortex. If this migration is disrupted, the new-born baby may suffer serious consequences, including intellectual impairment. What happens, however, if the migration takes place but is delayed? Researchers at the University of Geneva (UNIGE), Switzerland, have discovered that even a slight delay may lead to behavioural disorders that are similar to autistic characteristics in human. Furthermore, they found that these disorders are due to the abnormally low activity of the late neurons, which leads to permanent deficit of interneuronal connections. The Geneva neuroscientists succeeded in correcting the activity of the relevant neurons, thereby restoring the missing connections and preventing the appearance of behavioural disorders. The results, which are published in the journal Nature Communications, will open up new avenues for preventing neurodevelopmental disorders linked to the cerebral cortex.

How a 'flipped' gene helped butterflies evolve mimicry

Female swallowtail butterflies do something a lot of butterflies do to survive: they mimic wing patterns, shapes and colors of other species that are toxic to predators. Some - but not all - swallowtail species have evolved several different forms of this trait. But what kind of genetic changes led to these various disguises, and why would some species maintain an undisguised form when mimicry provides an obvious evolutionary advantage?

A little stress is good for cellular health and longevity

Northwestern University molecular bioscientists have discovered that a little stress can be good for cellular health. The findings will help researchers better understand the molecular mechanisms that drive aging and risk for age-associated degenerative diseases.

'Zombie ant' brains left intact by fungal parasite

A fungal parasite that infects ants and manipulates their behavior to benefit the fungus' reproduction accomplishes this feat without infecting the ants' brains, according to a study led by Penn State researchers.

Researchers identify defense mechanism of malaria parasite

Portuguese researchers at Instituto de Medicina Molecular (iMM) Lisboa have identified a defense mechanism by which the Plasmodium parasite can survive inside its host's liver cells, a crucial stage in which it acquires the capacity to infect red blood cells, causing the symptoms associated with malaria.

Detecting new proteins in active brains of mice

The complexity of living things is driven, in large part, by the huge diversity of cell types. Since all cells of an organism share the same genes, the diversity of cells must come from the particular proteins that are expressed. Cells in the brain are generally divided into neurons and glia. Within these two categories, however, lies a large diversity of cell types that we are only beginning to discover. The diversity of cell types in brain and other tissues has recently been expanded by new techniques, like RNA-sequencing, that identify and measure the mRNAs present in a cell, the so-called transcriptome. Although mRNAs are the template for proteins, the transcriptome is a poor proxy for proteins that a cell actually makes, the proteome. Scientists from the Max Planck Institute for Brain Research in Frankfurt now developed new methods to detect real-time changes in the proteome.

Bonobos help strangers without being asked

A passer-by drops something and you spring to pick it up. Or maybe you hold the door for someone behind you. Such acts of kindness to strangers were long thought to be unique to humans, but recent research on bonobos suggests our species is not as exceptional in this regard as we like to think.

How climate change may reshape subalpine wildflower communities

With climate change, Mount Rainier floral communities could 'reassemble' with new species relationships, interactions

Findings probe cell cooperation, 'en masse' migration

New research findings are revealing secrets about how living cells "cooperate" with each other, joining into groups that migrate collectively and alter tissue.

Is frozen cod just as good as fresh?

Is frozen cod just as good as fresh? Yes. As long as it is handled properly, new research reveals.

Why plants form sprouts in the dark

A signal from the cell wall decides that, in the dark, seeds grow into long yellow sprouts, instead of turning green and forming leaves. The signal that switches on the darkness programme in seedling development has not hitherto been identified. Earlier studies had shown that these processes involve photoreceptors inside plant cells. One vital signal outside the cells has now been described by the team of Prof Dr Ute Krämer and Dr Scott Sinclair at Ruhr-Universität Bochum, in collaboration with Prof Dr Dominik Begerow, likewise from Bochum, as well as colleagues from Australia, France, Switzerland, and from the Max Planck Institute of Plant Breeding Research in Cologne, in the journal Current Biology. The article was published online on November 2, 2017.

How far did you fall from the tree? Scientists estimate the mutation rate from chimpanzee parents to their offspring

Mutations generate genetic variation, and are a major driving force of evolution. Therefore, examining mutation rates and modes are essential to better understand the genetic basis for physiology and evolution.

Use of glow sticks in traps greatly increases amphibian captures in study

With amphibian populations declining around the world and funds to find the causes scarce, a team of Penn State researchers has shown that an unorthodox tactic will make it easier and therefore less expensive to capture adult salamanders and frogs.

Current cattle injections increase the risk of injury, research finds

Research by experts at The University of Nottingham suggests that current injection techniques in UK dairy cattle need to change to avoid the risk of nerve injury.

Researchers identify the yeast genes behind rose and honeyed flavors in beer and wine

A flavor compound called phenylethyl acetate imparts a hint of rose or honey to wherever it's found—a dab of perfume, a sip of wine, a slug of beer. Microbiologists in Belgium have used genetic mapping to identify, for the first time, specific yeast genes that produce higher levels of this aroma in alcoholic beverages. The new finding joins other recent work connecting genes to flavors in wines and beers, and may be used to grow yeasts that produce new flavors.

It takes a microclimate to raise a pinyon tree

With all the discussion about global climate change effects, new research shows that another kind of climate is an important factor in regional pinyon pine tree recovery after drought events - the microclimate.

Kenya male lions seen in intimate act; bonding, experts say

Recent photos taken in a Kenyan wildlife area show a rare sight: a male lion mounting another male lion in what resembles a sexual act but is possibly a way of showing dominance.

Monster fish of the deep

Do bugs gross you out? You haven't seen anything yet. To get some really weird creatures, you've got to look in the deep sea.

Book describes all 451 families of flowering plants, ferns, lycopods and gymnosperms

Humans are completely dependent on plants and their products. Without plants, there would be no food to eat, no air to breathe and no clean water to drink. Plants give us building materials and fibres for paper, clothes and ropes. Dyes and ornamental plants brighten up our lives. Many medicines and drugs are also still harvested directly from plants. Without being able to accurately identify plants, none of this would be possible.

The wild ass returns

On 24th October 2017, a first group of nine animals was released into an acclimatisation enclosure on the edge of the Altyn Dala protected area in central Kazakhstan. The animals had been transported 1200 km by helicopter from Altyn Emel National Park in the southeast of the country. They will be released in early spring. This is the first step in a multi-year project that aims to restore the full range of large herbivores to this unique area of steppe habitat.

Novel intermolecular surface force reveals actomyosin driving mechanism

The actin and myosin complex (actomyosin) generates contraction force of a muscle utilizing the adenosine triphosphate (ATP) hydrolysis reaction. Many attempts have thus been made to explain the molecular origin of the actomyosin motility.
