Security gaps identified in LTE mobile telephony standard

By abusing security weaknesses in the LTE mobile telephony standard, attackers are able to identify which web pages a user visits and to reroute him to a scam website. This is the result of a study carried out by security experts from Horst Görtz Institute at Ruhr-Universität Bochum. All devices using LTE, also referred to as 4G, are affected—i.e. almost all mobile phones and tablets, as well as certain household devices connected to the network. The weaknesses are impossible to close; and they are also still present in the upcoming mobile telephony standard 5G, the standardization of which is currently pending. Still, the problem may be stemmed with the aid of other security mechanisms in browsers or apps.

Supercomputers help design mutant enzyme that eats plastic bottles

A dump truck's worth of plastic empties into the ocean every minute. Worldwide, humankind produces over 300 million tons of plastic each year, much of which is predicted to last centuries to millennia and pollutes both aquatic and terrestrial environments. PET plastic, short for polyethylene terephthalate, is the fourth most-produced plastic and is used to make things like beverage bottles and carpets, the latter essentially not being recycled. Some scientists are hoping to change that, using supercomputers to engineer an enzyme that breaks down PET. They say it's a step on a long road toward recycling PET and other plastics into commercially valuable materials at industrial scale.

A DNA-level biomarker (MGMT promoter methylation) can be used to help predict survival outcomes in patients with high-risk, low-grade gliomas, according to a new study conducted through the NRG Oncology/RTOG collaborative clinical trials group and led by scientists at The Ohio State University Comprehensive Cancer Center—Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC—James).

'Music of speech' linked to brain area unique to humans

We humans are the only primates that can flexibly control the pitch of our voices. This melodic control is not just important for our singing abilities: Fluctuating pitch also conveys critical information during speech—including the speaker's mood, words of emphasis, or whether a sentence is a statement or a question. Some tonal languages, like Mandarin Chinese, even use pitch to give different meanings to otherwise identical words.

Novel drug therapy partially restores hearing in mice

For some bladder cancer patients, simple test could reduce over-treatment, ease high cost

Bladder cancer is relatively common and imposes the highest per patient cost on the U.S. health care system than the management of any other cancer type. Now, a new test could be key to reducing the cost of care while at the same time, relieving some patients of unneeded over-treatment, say investigators led by Georgetown Lombardi Comprehensive Cancer Center researchers.

Mutations in gene TRAF7 are associated with a multisystem disorder

A group of seven patients presenting with a similar disorder of unknown origin now know of a possible genetic root of their condition. A team of researchers sequenced all the protein-coding genes in the patients' genomes and identified four different mutations in the gene TRAF7. The researchers report in the American Journal of Human Genetics that in six individuals the mutations are de novo, meaning they are not present in the parents. Laboratory studies showed that the mutations resulted in a reduction of the normal activity of a cellular pathway called ERK1/2. Altogether, the results suggest that these mutations in TRAF7 are likely associated with the multisystem disorder presented by the patients.

Moving a cardiac regulatory protein to the right place

The largest known protein, titin, named for the Titan giants of Greek mythology, is a molecular spring found in cardiac muscle. It provides structural support and maintains tension during muscle stretching.

Certain antibodies in a patient's blood stream may enable life-threatening bacterial infections to spread instead of fighting them off, a University of Queensland study has found.

Study reveals secrets of "hot" and "cold" pancreatic cancer tumors

So-called "hot" tumors filled with T cells are often considered to be more sensitive to immunotherapy compared to "cold" tumors with fewer T cells, but a clear demonstration of why has eluded cancer biologists—until now. A team from Penn Medicine's Abramson Cancer Center (ACC) discovered that whether a tumor is hot or cold is determined by information embedded in the cancer cells themselves. In a new study published this week in Immunity, researchers probe the role of "tumor heterogeneity," a cancer cells' ability to move, replicate, metastasize, and respond to treatment. These new findings could help oncologists more precisely tailor treatments to a patient's unique tumor composition.

Proteins linked to scrub typhus infection are shown to inhibit immune response

High-protein formula increases the risk of excess body fat in children

Feeding infants with high-protein formula increases the risk of developing excess body fat by the age of 6. Moreover, in many such cases, Body Mass Index (BMI) does not reflect the true level of body fat, as LMU researchers have now shown.

Who wants to live to 100?

While the ageing of society has become one of the givens in today's world, less is made of the lived experience of the very elderly in society. And although there is some suggestion that the much trumpeted steady expansion of the human lifespan has begun to slow down, the numbers of very old people continue to grow. Despite this, debates about the resourcing of universal health and social care tend not to examine the costs associated with extreme ageing. Yet the problem of chronic conditions and multiple morbidity is greatest among octagenerians and nonagenarians.

Kidney disease patients' experience of care and illness can take a large emotional toll

For patients with advanced kidney disease, interactions with clinicians and with the wider health system, combined with patients' own struggle to understand their illness, can exact a large emotional toll.

Smoking associated with delayed shinbone healing

In adults, tibia (shinbone) fractures are usually fixed through the surgical implantation of a slender metal rod called an intramedullary nail in the hollow space within the bone. This treatment is generally effective for tibial fractures. However, in 10% to 15% of cases the bone fails to heal in a timely manner, resulting in a nonunion—or arrested healing.

CMS Policy to reduce hospital-acquired conditions had minimal impact

Hospitals may have avoided financial penalties by billing hospital-associated conditions (HAC) as present at the time of the patient's admission, supporting prior work that showed that a Medicare policy designed to monetarily penalize hospitals for preventable complications had an insignificant impact on reducing healthcare-associated infections. The new research was published today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. In addition, the targeted billing codes were rarely used by hospitals, far less than expected based on national estimates; and even when hospitals billed for HACs during a hospitalization, this infrequently affected the diagnosis-related group (DRG) assignment, impacting hospital reimbursement.

Biology news

What makes dogs man's best friend?

From pugs to labradoodles to huskies, dogs are our faithful companions. They live with us, play with us and even sleep with us. But how did a once nocturnal, fearsome wolf-like animal evolve over tens of thousands of years to become beloved members of our family? And what can dogs tell us about human health? Through the power of genomics, scientists have been comparing dog and wolf DNA to try and identify the genes involved in domestication.

How the flu virus builds a better mousetrap

For the first time, scientists have directly visualized in real-time structural changes in the surface protein of the influenza virus that may help the virus to fuse with and enter target cells before hijacking their functions. Researchers at Tufts University School of Medicine found that single molecules of the protein hemagglutinin (HA) that reside on the surface of the virus unfold to stretch toward target cells, then refold and try again 5 to 10 times per second. The discovery shows the flu virus to be more dynamic than previously thought and may help efforts to develop more effective vaccines and better understand other viruses such as Ebola, HIV, and SARS. The research appears in the journal Cell online June 28 and in print August 9.

I am human, hear me roar: Judging formidability from human vocalizations

Many animals—including sea lions, red deer, and dogs—use vocalizations to judge one another's size and physical formidability when in competition for mates or other resources. Now, researchers reporting in the journal iScience on June 28 have found that humans can use nonverbal vocal cues, including aggressive roars, in a similar way. The new evidence is the first to show that, from a vocalization alone, human listeners can estimate whether another person is stronger or weaker or taller or shorter than they are with a high degree of accuracy.

Ancient Moroccan dental remains elucidate history of long-lost African fauna

Long before rhinoceros, giraffes, hippos, and antelopes roamed the African savannah, a group of large and highly specialized mammals known as embrithopods inhabited the continent. The most well known is Arsinoitherium, an animal that looked much like a rhinoceros but was in fact more closely related to elephants, sea cows, and hyraxes. Now, researchers reporting in Current Biology on June 28 offer a glimpse into this ancient past with the discovery of the earliest and most ancient embrithopod yet described.

What's giant panda conservation worth? Billions every year, study shows

In China, the giant panda is clearly a cultural icon. And yet panda conservation, and the panda itself, is often criticized because of the associated cost. But an analysis reported in Current Biology on June 28 shows that panda conservation has great value that extends far beyond protection of pandas themselves.

Cheating on cheaters—exploring bacterial social interactions to manipulate bacterial pathogens

A new study, to be published in Current Biology on 28 June, proposes new strategies to induce the collapse of bacterial populations by manipulating social interactions in the human pathogen Pseudomonas aeruginosa, a bacterium that causes chronic lung infections.

Molecular vestiges resolve the controversial evolution of the testicular position in mammals

The loss of anatomical features is a frequent evolutionary event. For example, humans and other great apes have lost their tails and whales have lost their legs. The most convincing evidence comes from the presence of vestiges in fossils. Unfortunately, the fossil record mostly preserves vestiges of hard structures such as bones or teeth. Consequently, resolving the evolution of soft-tissue structures such as muscle or brain tissue requires analytical methods. A team of researchers from the Max Planck Institute of Molecular Cell Biology and Genetics, the Max Planck Institute for the Physics of Complex Systems, the Senckenberg Natural History Collections Dresden and the Natural History Museum Frankfurt now provides a new approach to resolve the evolution of soft-tissue structures, focusing on the evolution of testes in mammals.

Could electricity-producing bacteria help power future space missions?

Humans aren't the only ones who have harnessed the power of electricity. Some bacteria do this, too, by producing structures that extend from their surface like wires to transfer electrons over distances. Now, scientists at NASA's Ames Research Center in California's Silicon Valley are exploring this phenomenon to see if they can make use of these special microbes to perform essential functions on future space missions—from generating electricity to treating wastewater or producing medicines. With an experiment launching to the International Space Station, researchers will see whether the microbes work the same in space as they do on Earth.

Chimpanzees start using a new tool-use gesture during an alpha male take over

Similar to humans, non-human primates combine gestures, facial expressions, and vocalizations in various ways to communicate effectively. Researchers of the Max Planck Institute for Evolutionary Anthropology investigated one such signal, the 'leaf clip' gesture, which re-emerged in a wild chimpanzee group during an alpha takeover. Importantly, the gesture was produced only by adult male chimpanzees, immediately preceded their pant hoot vocalizations and was associated with acoustic changes in those calls.

Organizing a cell's genetic material from the sidelines

A tremendous amount of genetic material must be packed into the nucleus of every cell—a tiny compartment. One of the biggest challenges in biology is to understand how certain regions of this highly packaged DNA can be called upon so that the genes encoded in them can be "turned on" or expressed and used to manufacture RNA and proteins.

Crows 'reverse engineer' tools from memory: study

Molecular brake on human cell division prevents cancer

Researchers at Karolinska Institutet, Sweden, and the University of Sussex, England, have discovered that the process of copying DNA generates a brake signal that stalls cell division. This molecular brake ensures that the cell has two complete copies of DNA before it divides and thus prevents DNA damage and cancer development. The study is published in the scientific journal Molecular Cell.

Study finds benefits and tradeoffs in feeding rice bran to pigs

Rice is the third most widely grown cereal grain worldwide, and the bran left over from milling white rice is available in large quantities for livestock feed. Rice bran is high in unsaturated fatty acids, but limited information is available about effects of rice bran on growth performance of growing-finishing pigs and impacts on meat and carcass quality. A new study from the University of Illinois provides this information for the first time.
