The new target that enables ransomware hackers to paralyze dozens of towns and businesses at once

Posted by in categories: biotech/medical, business, cybercrime/malcode

Cybercriminals are zeroing in on the managed service providers that handle computer systems for local governments and medical clinics.

On July 3, employees at Arbor Dental in Longview, Washington, noticed glitches in their computers and couldn’t view X-rays. Arbor was one of dozens of dental clinics in Oregon and Washington stymied by a ransomware attack that disrupted their business and blocked access to patients’ records.

But the hackers didn’t target the clinics directly. Instead, they infiltrated them by exploiting vulnerable cybersecurity at Portland-based PM Consultants Inc., which handled the dentists’ software updates, firewalls and data backups. Arbor’s frantic calls to PM went to voicemail, said Whitney Joy, the clinic’s office coordinator.

New Wearable Device Could Accurately Detect Cancer

Posted by in categories: biotech/medical, wearables

cancer

Biopsies are currently the best way to detect cancer, but they’re invasive, uncomfortable, and can take a while to come back. Researchers have long been trying to find ways to eliminate the need for biopsies, and a team from the University of Michigan may have found one. Their new device, which is currently being tested, may be able to detect cancer cells that are circulating in a patient’s blood.

The University of Michigan team calls their new device “the epitome of precision medicine.” Dr. Daniel Hayes, Professor of Breast Cancer Research at the University of Michigan Rogel Cancer center, believes that getting cancer cells from a patient’s blood could help researchers to learn more about the makeup of the tumor. He and his team created a wearable device that looks through the blood to filter out cancerous cells. If the device is found to be successful, it may eventually replace liquid biopsies (blood or urine samples) that pick up cancer markers.

Dietary supplement may help with schizophrenia

Posted by in categories: biotech/medical, evolution, neuroscience

A dietary supplement, sarcosine, may help with schizophrenia as part of a holistic approach complementing antipsychotic medication, according to a UCL researcher.

In an editorial published in the British Journal of Psychiatry, Professor David Curtis (UCL Genetics, Evolution & Environment and QMUL Centre for Psychiatry) suggests the readily available product could easily be incorporated into treatment plans, while calling for clinical trials to clarify the benefit and inform guidelines.

“Sarcosine represents a very logical treatment and the small number of so far do seem to show that it can be helpful. It certainly seems to be safe and some patients report feeling better on it,” he said.

Students make neutrons dance beneath UC Berkeley campus

Posted by in categories: biotech/medical, nuclear energy

In an underground vault enclosed by six-foot concrete walls and accessed by a rolling, 25-ton concrete-and-steel door, University of California, Berkeley, students are making neutrons dance to a new tune: one better suited to producing isotopes required for geological dating, police forensics, hospital diagnosis and treatment.

Dating and forensics rely on a spray of neutrons to convert atoms to radioactive isotopes, which betray the chemical composition of a substance, helping to trace a gun or reveal the age of a rock, for example. Hospitals use isotopes produced by neutron irradiation to kill tumors or pinpoint diseases like cancer in the body.

For these applications, however, only nuclear reactors can produce a strong enough spray of neutrons, and there are only two such reactors west of the Mississippi.

A smart artificial hand for amputees merges user and robotic control

Posted by in categories: biotech/medical, cyborgs, engineering, robotics/AI

EPFL scientists are developing new approaches for improved control of robotic hands—in particular for amputees—that combines individual finger control and automation for improved grasping and manipulation. This interdisciplinary proof of concept between neuroengineering and robotics was successfully tested on three amputees and seven healthy subjects. The results are published in today’s issue of Nature Machine Intelligence.

The technology merges two concepts from two different fields. Implementing them both together had never been done before for robotic hand control, and contributes to the emerging field of shared control in neuroprosthetics.

Chinese Scientists Try to Cure One Man’s HIV With Crispr

Posted by in categories: biotech/medical, genetics

In July of 2017, doctors in Beijing blasted the patient with chemicals and radiation to wipe out his bone marrow, making space for millions of stem cells they then pumped into his body through an IV. These new stem cells, donated by a healthy fellow countryman, would replace the patient’s unhealthy ones, hopefully resolving his cancer. But unlike any other routine bone marrow transplant, this time researchers edited those stem cells with Crispr to cripple a gene called CCR5, without which HIV can’t infiltrate immune cells.


For the first time, a patient got treated for HIV and cancer at the same time, with an infusion of gene-edited stem cells. The results? Mixed.

How Bullying May Shape Adolescent Brains

Posted by in categories: biotech/medical, health, neuroscience

In recent years, a steadily increasing volume of data has demonstrated that peer victimization — the clinical term for bullying — impacts hundreds of millions of children and adolescents, with the effects sometimes lasting years and, possibly, decades. The problem is even recognized as a global health challenge by the World Health Organization and the United Nations. And yet, researchers maintain there is still a limited understanding of how the behavior may physically shape the developing brain.

New metamaterial morphs into new shapes, taking on new properties

Posted by in categories: biotech/medical, engineering, nanotechnology

A newly developed type of architected metamaterial has the ability to change shape in a tunable fashion.

While most reconfigurable materials can toggle between two distinct states, the way a switch toggles on or off, the new material’s shape can be finely tuned, adjusting its as desired. The material, which has potential applications in next-generation energy storage and bio-implantable micro-devices, was developed by a joint Caltech-Georgia Tech-ETH Zurich team in the lab of Julia R. Greer.

Greer, the Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering in Caltech’s Division of Engineering and Applied Science, creates materials out of micro- and nanoscale building blocks that are arranged into sophisticated architectures that can be periodic, like a lattice, or non-periodic in a tailor-made fashion, giving them unusual physical properties.
