Protein pileup affects social behaviors through altered brain signaling

Scientists at the RIKEN Center for Brain Science (CBS) have discovered that when a normal cellular cleanup process is disrupted, mice start behaving in ways that resemble human symptoms of autism spectrum disorder (ASD) and schizophrenia. They found that loss of normal autophagy, the process that recycles damaged cellular components such as proteins, influences how brain cells react to inhibitory signals from each other and contributes to the behavioral changes. This intricate signaling pathway could be a new therapeutic target for neurodevelopmental and neuropsychiatric disorders.

The protein p38-gamma identified as a new therapeutic target in liver cancer

An enzyme involved in cell stress responses could become a new pharmacological target in the treatment of liver cancer, a disease that currently has few available treatment options. The research team at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) led by Guadalupe Sabio has discovered that the protein p38γ, one of the four types of p38 kinase, is essential for the initiation of cell division in liver cells. This indicates that "p38γ could be a useful therapeutic target for liver cancer," says Sabio, adding, "We are now developing inhibitors of this protein to test in this cancer." The study has been published today in Nature.

Genetic defects without consequences

Many diseases are caused by genetic defects. However, their severity can vary among individual patients, so that even mild forms can occur. Scientists at the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now decrypted a molecular mechanism responsible for this phenomenon. Accordingly, the mRNA of the defective gene ensures that related genes are activated thereby compensating the defect. The researchers hope to make use of this mechanism for therapeutic approaches.

A dust-up: Microbes interact with harmful chemicals in dust

The dust that settles throughout our homes and offices almost always contains bits of chemicals that can cause problems for the human endocrine system, scientists say.

A new role for genetics in cancer therapy-induced cardiomyopathy

Recent advances in the development of cancer therapies have increased long-term survival and prognosis. However, the increased burden and prevalence of harmful side effects, including cardiomyopathy, have emerged alongside those therapeutic benefits. In particular, there have been increases in cancer therapy-induced cardiomyopathy (CCM)—a heart condition which may compromise a patient's quality of life and long-term prognosis after the cancer has been treated. And while certain clinical risk factors for CCM are known, the factors that contribute to an individual's susceptibility remain a mystery. A team of investigators from Brigham and Women's Hospital and Harvard Medical School finds that genetics may be at play and elucidates rare genetic variants which may influence risk for developing CCM. Results are published in Circulation.

Higher lead in topsoil boosts probability of cognitive difficulties in five-year-old boys

Soil contamination has long been recognized as a contributor to lead exposure in people and is now a health concern worldwide. In a new study, researchers sought to estimate the causal effects of exposure to lead in topsoil on the cognitive ability of 5-year-olds in the United States. The study found that higher lead in topsoil significantly increases the probability that 5-year-old boys will have cognitive difficulties but does not seem to affect 5-year-old girls. The researchers found the adverse effects in boys even in U.S. counties where the government considers the levels of lead concentration in the soil to be low.

Caregiving not as bad for your health as once thought, study says

For decades, articles in research journals and the popular press alike have reported that being a family caregiver takes a toll on a person's health, boosting levels of inflammation and weakening the function of the immune system. Now, after analyzing 30 papers on the levels of immune and inflammatory molecules in caregivers, Johns Hopkins researchers say the link has been overstated and the association is extremely small. Caregiver stress explains less than 1 percent of the variability in immune and inflammation biomarkers, they report. Their new meta-analysis was published March 10 in The Gerontologist.

Wildlife detectives aiming to protect endangered species have long been hobbled by the near impossibility of collecting DNA samples from rare and elusive animals. Now, researchers at Stanford and the National Centre for Biological Sciences at India's Tata Institute of Fundamental Research have developed a method for extracting genetic clues quickly and cheaply from degraded and left-behind materials, such as feces, skin or saliva, and from food products suspected of containing endangered animals.

Showy male primates have smaller testicles

Male primates equipped with all the bells and whistles to attract a female mate tend to have smaller gonads, according to a study by researchers at The University of Western Australia and University of Zurich.

Dolphins who help fishermen found to also hang out together between meals

A team of researchers with members from Brazil, South Africa and the U.S. has found an example of homophily among dolphins who work together with fishermen in Brazil for the mutual benefit of both. In their paper published in the journal Biology Letters, the group describes their study of the dolphins and what they found.

New imaging reveals previously unseen vulnerabilities of HIV

Imagine that HIV is a sealed tin can: if you opened it, what would you find inside? An international team led by researchers at the University of Montreal Hospital Research Centre (CRCHUM), Tufts University School of Medicine, and the University of Melbourne think they know. For the first time, they have visualized what the "open can" of the human immunodeficiency virus looks like, revealing a previously unknown virus shape and a very detailed image of the vulnerabilities of the virus.

Scientists invent time-saving technique to show how cells differentiate

Researchers with the Institute for Molecular Engineering at the University of Chicago have developed a new "lab-on-a-chip" that can examine thousands of individual live cells over a weeklong period, performing experiments that would take more than 1 million steps in a laboratory.

Ultrasound aligns living cells in bioprinted tissues

North Carolina State University researchers have developed a technique to improve the characteristics of engineered tissues by using ultrasound to align living cells during the biofabrication process.

Tiny traces of neonicotinoid pesticides impair insects' ability to spot predators

Traces of neonicotinoid pesticides can impair a flying insect's ability to spot predators and avoid collisions with objects in their path, new research by the University of Saskatchewan (USask) shows.

Evolution from water to land led to better parenting

The evolution of aquatic creatures to start living on land made them into more attentive parents, says new research on frogs led by the Milner Centre for Evolution at the University of Bath.

Long-lived bats could hold secrets to mammal longevity

University of Maryland researchers analyzed an evolutionary tree reconstructed from the DNA of a majority of known bat species and found four bat lineages that exhibit extreme longevity. They also identified, for the first time, two life history features that predict extended life spans in bats.

Pesticide cocktail can harm honey bees

A recently approved pesticide growing in popularity around the world was developed as a "bee safe" product, designed to kill a broad spectrum of insect pests but not harm pollinators.

Giant Antarctic sea spiders weather warming by getting holey

Scientists have wondered for decades why marine animals that live in the polar oceans and the deep sea can reach giant sizes there, but nowhere else. University of Hawai'i at Manoa zoology Ph.D. student Caitlin Shishido, with UH researcher Amy Moran and colleagues at the University of Montana, went to Antarctica to test the prevailing theory-the 'oxygen-temperature hypothesis'-that animals living in extreme cold can grow to giant sizes because their metabolisms are very slow. The animals they studied were sea spiders, marine relatives of land spiders that breathe through their legs.

The best place for a bird's voice box is low in the airway, researchers find

All air-breathing vertebrates have a larynx—a structure of muscles and folds that protects the trachea and, in many animals, vibrates and modulates to produce a stunning array of sounds.

New electron microscopy technique limits membrane destruction

Membrane proteins play an important role in many biological processes. Studies suggest they're targeted by more than 50% of all modern medicinal drugs. Unfortunately for researchers, determining their structures has been a longstanding challenge because it's difficult to track the protein without damaging the cellular membrane using current techniques. Not anymore.

Researchers explain signals of CpG 'traffic lights' in DNA

A research team featuring bioinformaticians from the Moscow Institute of Physics and Technology (MIPT) has identified reliable markers of gene activity. The discovery has potential for future applications in clinical practice. The findings are reported in BMC Genomics.

Empathy is the secret ingredient that makes cooperation – and civilization – possible

Human societies are so prosperous mostly because of how altruistic we are. Unlike other animals, people cooperate even with complete strangers. We share knowledge on Wikipedia, we show up to vote, and we work together to responsibly manage natural resources.

Cuba's worker bees boost thriving honey business

In the floral valleys of Cuba's Matanzas province, old fashioned farming means bees can swarm without the threat of pesticides that have decimated populations across the world.

Record Singapore bust puts scrutiny on overlooked pangolin (Update)

Singapore has seized more than 28 tons of pangolin scales belonging to around 38,000 of the endangered mammals over the past week, a global record that spurred calls for more protection for pangolins, which are used in traditional medicine.

New dimension to coral research

For the first time, international researchers have mapped the network of bacteria on coral reefs. They write about it in Nature Communications (9 April). Professor by special appointment Nicole de Voogd (Naturalis Biodiversity Center & Institute of Environmental Sciences) and two of her Ph.D. students co-authored the publication.

Too many pets are packing on too many pounds

Pets make us healthier. They can raise our spirits, extend our lives, lower our blood pressure and make us more active, research shows.
