Pot can cause serious illness due to its gene altering effects.


Scientists from The University of Western Australia have identified how using cannabis can alter a person’s DNA structure, causing mutations which can expose them to serious illnesses, and be passed on to their children and several future generations.

Although the association between use and severe illnesses such as cancer has previously been documented, how this occurs and the implications for was not previously understood.

Associate Professor Stuart Reece and Professor Gary Hulse from UWA’s School of Psychiatry and Clinical Sciences completed an extensive analysis of literary and research material to understand the likely causes and uncovered alarming information.

“If we can replace cement, partially or totally, with some other materials that may be readily and amply available in nature, we can meet our objectives for sustainability,” MIT Professor Oral Buyukozturk says. Image: Christine Daniloff/MITResearchers at MIT are seeking to redesign concrete — the most widely used human-made material in the world — by following nature’s blueprints.

In a paper published online in the journal Construction and Building Materials, the team contrasts cement paste — concrete’s binding ingredient — with the structure and properties of natural materials such as bones, shells, and deep-sea sponges. As the researchers observed, these biological materials are exceptionally strong and durable, thanks in part to their precise assembly of structures at multiple length scales, from the molecular to the macro, or visible, level.

From their observations, the team, led by Oral Buyukozturk, a professor in MIT’s Department of Civil and Environmental Engineering (CEE), proposed a new bioinspired, “bottom-up” approach for designing cement paste.

Bad with money? Blame it on your hormones according to Richard Thaler.


Let’s face it: most of us suck at managing money.

According to a National Bureau of Economics working paper published this March, roughly three quarters of all American households carry some form of debt. 40% haven’t paid off their credit cards. Nearly half have no savings at all. And the US isn’t alone: Canada, the UK and Australia are in roughly the same debt-ridden neighborhood.

There’s no doubt that we’re bad with money. But according to Richard Thaler, an economist at the University Chicago, we’re not (entirely) to blame.

Interesting.


The research, published in Nature Structural and Molecular Biology, explains how the gene encourages the attachment of the protein, ubiquitin, to other proteins and plays a vital role in DNA repair. Should the results be confirmed by further studies, it is possible that patients with certain genetic changes in BRCA1 could be identified as being at higher risk of breast and ovarian cancer.

Great news for precision medicine.


European regulators have given the green light for a British drug firm to produce the world’s first gene therapy treatment for children.

GlaxoSmithKline was given approval by the European Commission to provide the treatment to children with a rare immune disorder — which can be fatal for those affected.

The treatment, called Strimvelis, is the first stem cell gene therapy to treat children with severe combined immunodeficiency — commonly referred to as ‘bubble boy’ syndrome.

New fundamental research by UT Dallas physicists may accelerate the drive toward more advanced electronics and more powerful computers.

The scientists are investigating materials called topological insulators, whose surface electrical properties are essentially the opposite of the properties inside.

“These materials are made of the same thing throughout, from the interior to the exterior,” said Dr. Fan Zhang, assistant professor of physics at UT Dallas. “But, the interior does not conduct electrons — it’s an insulator — while the electrons on the surface are free to move around. The surface is therefore a conductor, like a metal, but it is in fact more robust than a metal.”
