New sequencing reveals genetic history of tomatoes

16-10-2014

An international team of researchers, led by the Chinese Academy of Agricultural Sciences in Beijing, published in the journal Nature Genetics a brief genomic history of tomato breeding, based on sequencing of 360 varieties of the tomato plant. The C.M. Rick Tomato Genetics Resource Center at UC ...

New blood test determines whether you have or are likely to get cancer

New research suggests that white blood cells exposed to UVA light in agar, to induce DNA damage, can predict if one has or is at risk for cancer

02-10-2014

A new research report published in the October 2014 issue of The FASEB Journal may make the early detection of cancer as easy as a simple blood test. This test, called the "lymphocyte genome sensitivity" (LGS) test, could not only detect some cancers earlier than ever before, but it may eliminate ...

Graphene imperfections key to creating hypersensitive 'electronic nose'

24-09-2014

Researchers have discovered a way to create a highly sensitive chemical sensor based on the crystalline flaws in graphene sheets. The imperfections have unique electronic properties that the researchers were able to exploit to increase sensitivity to absorbed gas molecules by 300 times. The study ...

Large study reveals new genetic variants that raise risk for prostate cancer

22-09-2014

In an analysis of genetic information among more than 87,000 men, a global team of scientists says it has found 23 new genetic variants – common differences in the genetic code -- that increase a man's risk for prostate cancer. The so-called "meta-analysis," believed to be the largest of its ...

Advanced light source sets microscopy record

Berkeley Lab researchers achieve highest resolution ever with X-ray microscopy

15-09-2014

A record-setting X-ray microscopy experiment may have ushered in a new era for nanoscale imaging. Working at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab), a collaboration of researchers used low energy or "soft" X-rays to image structures only five ...

Faster, cheaper tests for sickle cell

Newly developed test can identify sickle cell disease in minutes and could be used in rural clinics around the globe

03-09-2014

Within minutes after birth, every child in the U.S. undergoes a battery of tests designed to diagnose a host of conditions, including sickle cell disease. Thousands of children born in the developing world, however, aren't so lucky, meaning many suffer and die from the disease each year. A.J. ...

Genomic sequencing reveals mutations, insights into 2014 Ebola outbreak

Broad researchers and colleagues find clues about origin, transmission of deadly virus

01-09-2014

In response to an ongoing, unprecedented outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, in collaboration with the Sierra Leone Ministry of Health and Sanitation and researchers across institutions and continents, has ...

New analytical technology reveals 'nanomechanical' surface traits

01-09-2014

A new research platform uses a laser to measure the "nanomechanical" properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries. This new technique, called nanomechanical Raman spectroscopy, reveals ...

No excess baggage: Antarctic insect's genome, newly sequenced, is smallest to date

Researchers suggest bare-bones genome is adaptation to deep freeze

14-08-2014

Scientists who sequenced the genome of the Antarctic midge suspect the genome's small size – the smallest in insects described to date – can probably be explained by the midge's adaptation to its extreme living environment. The midge is a small, wingless fly that spends most of its two-year ...
