Motor behaviour—understanding the jerks that lurk in smooth movements

Apparently smooth continuous movements to trace moving objects harbour jerks. These jerks are absent when there is no object to be traced and so are thought to stem from changes in motor instructions anticipated and fed forward by the brain to compensate for sensorimotor time lags. However so far there is no conclusive evidence that this is the case. Now Yasuyuki Inoue and Yutaka Sakaguchi at the University of Electro-communications have demonstrated a method for analysing apparently smooth movements that may help to understand their jerky components.

From brain, to fat, to weight loss

Weight is controlled by the hormone leptin, which acts in the brain to regulate food intake and metabolism. However, it was largely unknown until now, how the brain signals back to the fat tissue to induce fat breakdown. Now, a breakthrough study led by Ana Domingos at Instituto Gulbenkian de Ciência (IGC; Portugal), in collaboration with Jeffrey Friedman's group at Rockefeller University (USA), has shown that fat tissue is innervated and that direct stimulation of neurons in fat is sufficient to induce fat breakdown. These results, published in the latest issue of the prestigious journal Cell, set up the stage for developing novel anti-obesity therapies.

New treatment may help overcome common pregnancy-related complication

Preeclampsia, when a pregnant woman develops high blood pressure and protein in the urine, is one of the most common medical complications of pregnancy, and the consequences for both mother and baby can be devastating.

The molecular interactions between the worm, mosquito and human are dynamic and delicately balanced, meaning that disrupting these interactions might be an avenue for the development new therapeutic treatments.

Gene expression studies reveal drug combination effective against schistosomiasis

Schistosomiasis is a neglected tropical disease caused by parasitic worms endemic in parts of Africa, Southeast Asia and Central and South America. It is currently treated by the drug praziquantel which, while both effective and cost efficient, does not prevent reinfection after the disease has cleared. Praziquantel is the only current treatment, and while no resistance has been observed in humans, animal models predict that repeated rounds of treatment may lead to the evolution of drug resistance. It is therefore important to explore both alternative treatments and synergistic therapies to expand the lifetime and effectiveness of the praziquantel treatment.

Negative spiritual beliefs associated with more pain and worse physical, mental health

Arteries better than veins for liquid biopsy

As the field of liquid biopsies for tracking disease progression and therapeutic response heats up, many doctors are looking for ways to apply this approach to their patients. Currently, assays for circulating tumor cells (CTCs) - one type of liquid biopsy - have been approved for diagnostic purposes in metastatic breast, colorectal, or prostate cancer. In these diseases, the presence of CTCs in the peripheral blood is associated with decreased progression-free survival and decreased overall survival. The major challenge for this technology is that CTCs are not always found in the blood of patients with aggressive disease who would be expected to have high numbers. Now, researchers at Thomas Jefferson University investigating uveal melanoma, a type of melanoma that originates in the eye, have shown that the low numbers could simply be explained by where the blood is drawn - whether from a vein or an artery.

Rapidly assessing the next influenza pandemic

In the dark polar winter, the animals aren't sleeping

You might expect that little happens in the Arctic Ocean during the cold and dark winter. But that just isn't so, according to researchers who have sampled the activities of many different species during three consecutive winters in Kongsfjorden, Svalbard. Their findings are published in the Cell Press journal Current Biology on September 24.

The life and times of domesticated cheese-making fungi

People sure love their cheeses, but scientists have a lot to learn about the fungi responsible for a blue cheese like Roquefort or a soft Camembert. Now researchers reporting in the Cell Press journal Current Biology on September 24 have pieced together the story of those Penicillium fungi, based on the genomes of 14 fungal species. The findings reveal an important role for the horizontal transfer of genes from one species to another in the fungi's ability to trade their freedom in for the domesticated life.

Researchers uncover genetic basis for kin recognition in mice

Researchers from the University of Liverpool have identified the genetic basis of how mice can recognise close relatives, even if they have never encountered them before.

Wine's darkest secret revealed - it's all in the fungi

Being a winemaker is a specialised calling, requiring intimate knowledge of soil composition, seasons and weather, chemistry, flavour, even marketing and sales.

Newly discovered metabolism certifies evolutionary advantage for yeast

Duplicate copies of genes safeguard survival of the biotech yeast Pichia pastoris in environments where only methanol is present as feed. A recently elucidated metabolism is similar to that used by plants for the utilization of carbon dioxide.

Key genes in epidermal cell differentiation are essential for survival of plants

The bodies of plants consist of only three tissue systems: the outermost epidermal tissue, the inner tissue, and the vascular tissue. The epidermis plays an important role in protecting the body of a plant from external stresses, preventing organ fusions, and determining final organ shapes.

After 100 years in captivity, a look at the world's last truly wild horses

In the 1870s, the world's last truly wild horses, known as Przewalski's horses, lived in the Asian steppes of Mongolia and China. But by the 1960s, those wild horses were no longer free. Only one captive population remained, descended from about a dozen wild-caught individuals and perhaps four domesticated horses. Thanks to major conservation efforts, the current population of Przewalski's horses numbers over 2,000 individuals, with about a quarter living in reintroduction reserves.

Using flies to understand how pregnancy drives food cravings
